Subpart A—General

   top

§ 36.1   General.

   top

   (a)  This  part  contains  an  outline  of  separations procedures for
   telecommunications  companies  on  the station-to-station basis. These
   procedures are applicable either to property costs, revenues, expenses,
   taxes, and reserves as recorded on the books of the company or to estimated
   amounts.

   (1) Where a value basis is used instead of book costs, the “costs” referred
   to are the “values” of the property derived from the valuation.

   (b) The separations procedures set forth in this part are designed primarily
   for the allocation of property costs, revenues, expenses, taxes and reserves
   between state and interstate jurisdictions. For separations, where required,
   of  the  state portion between exchange and toll or for separations of
   individual exchanges or special services, further analyses and studies may
   be required to adapt the procedures to such additional separations.

   (c)  The fundamental basis on which separations are made is the use of
   telecommunications plant in each of the operations. The first step is the
   assignment of the cost of the plant to categories. The basis for making this
   assignment is the identification of the plant assignable to each category
   and the determination of the cost of the plant so identified. The second
   step is the apportionment of the cost of the plant in each category among
   the operations by direct assignment where possible, and all remaining costs
   are assigned by the application of appropriate use factors.

   (d) In assigning book costs to categories, the costs used for certain plant
   classes  are  average  unit  costs which equate to all book costs of a
   particular account or subaccount; for other plant classes, the costs used
   are those which either directly approximate book cost levels or which are
   equated to match total book costs at a given location.

   (e) The procedures outlined herein reflect “short-cuts” where practicable
   and where their application produces substantially the same separations
   results as would be obtained by the use of more detailed procedures, and
   they assume the use of records generally maintained by Telecommunications
   Companies.

   (f) The classification to accounts of telecommunications property, revenues,
   expenses, etc., set forth in this manual is that prescribed by the Federal
   Communications   Commission's   Uniform   System   of   Accounts   for
   Telecommunications Companies.

   (g)  In  the  assignment  of  property  costs to categories and in the
   apportionment of such costs among the operations, each amount so assigned
   and apportioned is identified as to the account classification in which the
   property is included. Thus, the separated results are identified by property
   accounts and apportionment bases are provided for those expenses which are
   separated on the basis of the apportionment of property costs. Similarly,
   amounts  of  revenues and expenses assigned each of the operations are
   identified as to account classification.

   (h)  The  separations  procedures described in this part are not to be
   interpreted as indicating what property, revenues, expenses and taxes, or
   what items carried in the income, reserve and retained earnings accounts,
   should or should not be considered in any investigation or rate proceeding.

§ 36.2   Fundamental principles underlying procedures.

   top

   (a) The following general principles underlie the procedures outlined in
   this part:

   (1)  Separations  are  intended to apportion costs among categories or
   jurisdictions by actual use or by direct assignment.

   (2)  Separations  are  made  on  the  “actual  use” basis, which gives
   consideration to relative occupancy and relative time measurements.

   (3) In the development of “actual use” measurements, measurements of use are
   (i)  determined  for telecommunications plant or for work performed by
   operating forces on a unit basis (e.g., conversation-minute-kilometers per
   message, weighted standard work seconds per call) in studies of traffic
   handled or work performed during a representative period for all traffic and
   (ii) applied to overall traffic volumes, i.e., 24-hour rather than busy-hour
   volumes.

   (b) Underlying the procedures included in this manual for the separation of
   plant costs is an over-all concept which may be described as follows:

   (1) Telecommunications plant, in general, is segregable into two broad
   classifications,  namely, (i) interexchange plant, which is plant used
   primarily to furnish toll services, and (ii) exchange plant, which is plant
   used primarily to furnish local services.

   (2) Within the interexchange classification, there are three broad types of
   plant, i.e., operator systems, switching plant, and trunk transmission
   equipment. Within the exchange classification there are four board types of
   plant,  i.e.,  operator  systems, switching plant, truck equipment and
   subscriber plant. Subscriber plant comprises lines to the subscriber.

   (3) In general, the basis for apportioning telecommunications plant used
   jointly for state and interstate operations are:

   (i) Operator work time expressed in weighted standard work seconds is the
   basis for measuring the use of operator systems.

   (ii) Holding-time-minutes is the basis for measuring the use of local and
   toll switching plant.

   (iii) Conversation-minute-kilometers or conversation minutes is the basis
   for  measuring the use of interexchange circuit plant and holding-time
   minutes is the basis for measuring the use of exchange trunk plant. While
   the  use  of  holding-time-minute-kilometers  is the basic fundamental
   allocation factor for interexchange circuit plant and exchange trunk plant,
   the use of conversation-minute-kilometers or conversation-minutes for the
   allocation of interexchange circuit plant and holding-time minutes for the
   allocation of exchange trunk plant are considered practical approximations
   for separations between state and interstate operations when related to the
   broad types of plant classifications used herein.

   (iv) Message telecommunications subscriber plant shall be apportioned on the
   basis  of a Gross Allocator which assigns 25 percent to the interstate
   jurisdiction and 75 percent to the state jurisdiction.

   (c) Property rented to affiliates, if not substantial in amount, is included
   as used property of the owning company with the associated revenues and
   expenses treated consistently: Also such property rented from affiliates is
   not included with the used property of the company making the separations;
   the rent paid is included in its expenses. If substantial in amount, the
   following treatment is applied:

   (1) In the case of property rented to affiliates, the property and related
   expenses and rent revenues are excluded from the telephone operations of the
   owning company, and

   (2) In the case of property rented from affiliates, the property and related
   expenses are included with, and the rent expenses are excluded from, the
   telephone operations of the company making the separation.

   (d) Property rented to or from non-affiliates is usually to be included as
   used  property  of the owning company with the associated revenues and
   expenses treated consistently. In the event the amount is substantial, the
   property involved and the revenues and expenses associated therewith may be
   excluded  from or included in the telecommunications operations of the
   company.  When  required,  the  cost  of  property  rented  to or from
   non-affiliates is determined using procedures that are consistent with the
   procedures for the allocation of costs among the operations.

   (e) Costs associated with services or plant billed to another company which
   have once been separated under procedures consistent with general principles
   set forth in this part, and are thus identifiable as entirely interstate or
   State in nature, shall be directly assigned to the appropriate operation and
   jurisdiction.

   [ 52 FR 17229 , May 6, 1987, as amended at  58 FR 44905 , Aug. 25, 1993;  71 FR 65745 , Nov. 9, 2006]

§ 36.3   Freezing of jurisdictional separations category relationships and/or
allocation factors.

   top

   (a)  Effective July 1, 2001, through June 30, 2006, all local exchange
   carriers subject to part 36 rules shall apportion costs to the jurisdictions
   using their study area and/or exchange specific jurisdictional allocation
   factors calculated during the twelve month period ending December 31, 2000,
   for  each of the categories/sub-categories as specified herein. Direct
   assignment of private line service costs between jurisdictions shall be
   updated annually. Other direct assignment of investment, expenses, revenues
   or taxes between jurisdictions shall be updated annually. Local exchange
   carriers that invest in telecommunications plant categories during the
   period July 1, 2001, through June 30, 2006, for which it had no separations
   allocation factors for the twelve month period ending December 31, 2000,
   shall apportion that investment among the jurisdictions in accordance with
   the  separations  procedures in effect as of December 31, 2000 for the
   duration of the freeze.

   (b) Effective July 1, 2001, through June 30, 2006, local exchange carriers
   subject to price cap regulation, pursuant to §61.41, shall assign costs from
   the  part 32 accounts to the separations categories/sub-categories, as
   specified  herein,  based  on  the  percentage  relationships  of  the
   categorized/sub-categorized costs to their associated part 32 accounts for
   the twelve month period ending December 31, 2000. If a part 32 account for
   separations  purposes  is categorized into more than one category, the
   percentage relationship among the categories shall be utilized as well.
   Local exchange carriers that invest in types of telecommunications plant
   during the period July 1, 2001, through June 30, 2006, for which it had no
   separations category investment for the twelve month period ending December
   31,  2000,  shall  assign such investment to separations categories in
   accordance with the separations procedures in effect as of December 31,
   2000. Local exchange carriers not subject to price cap regulation, pursuant
   to §61.41 of this chapter, may elect to be subject to the provisions of
   §36.3(b). Such election must be made prior to July 1, 2001. Local exchange
   carriers electing to become subject to §36.3(b) shall not be eligible to
   withdraw from such regulation for the duration of the freeze. Local exchange
   carriers participating in Association tariffs, pursuant to §69.601 of this
   chapter et seq., shall notify the Association prior to July 1, 2001, of such
   intent to be subject to the provisions of §36.3(b). Local exchange carriers
   not participating in Association tariffs shall notify the Commission prior
   to July 1, 2001, of such intent to be subject to the provisions of §36.3(b).

   (c)  Effective July 1, 2001, through June 30, 2006, any local exchange
   carrier that sells or otherwise transfers exchanges, or parts thereof, to
   another carrier's study area shall continue to utilize the factors and, if
   applicable, category relationships as specified in §§36.3(a) and (b).

   (d)  Effective July 1, 2001, through June 30, 2006, any local exchange
   carrier that buys or otherwise acquires exchanges or part thereof, shall
   calculate new, composite factors and, if applicable, category relationships
   based on a weighted average of both the seller's and purchaser's factors and
   category relationships calculated pursuant to §§36.3(a) and 36.3(b). This
   weighted average should be based on the number of access lines currently
   being served by the acquiring carrier and the number of access lines in the
   acquired exchanges.

   (1) To compute the composite allocation factors and, if applicable, the
   composite category percentage relationships of the acquiring company, the
   acquiring carrier shall first sum its existing (pre-purchase) access lines
   (A) with the total access lines acquired from selling company (B). Then,
   multiply its factors and category relationship percentages by (A/(A+B)) and
   those of the selling company by (B/(A+B)) and sum the results.

   (2)  For  carriers  subject to a freeze of category relationships, the
   acquiring  carrier should remove all categories of investment from the
   selling  carrier's list of frozen category relationships where no such
   category  investment  exists within the sold exchange(s). The seller's
   remaining category relationships must then be increased proportionately to
   total 100 percent. Then, the adjusted seller's category relationships must
   be combined with those of the acquiring carrier as specified in §36.3(d)(1)
   to  determine  the  category relationships for the acquiring carrier's
   post-transfer study area.

   (e) Any local exchange carrier study area converting from average schedule
   company status, as defined in §69.605(c) of this chapter, to cost company
   status during the period July 1, 2001, through June 30, 2006, shall, for the

Central Office Equipment

   top

§ 36.121   General.

   top

   (a) The costs of central office equipment are carried in the following
   accounts:
   Central Office Switching     Account 2210.
   Non-digital Switching        Account 2211.
   Digital Electronic Switching Account 2212.
   Operator Systems             Account 2220.
   Central Office—Transmission  Account 2230.
   Radio Systems                Account 2231.
   Circuit Equipment            Account 2232.

   (b) Records of the cost of central office equipment are usually maintained
   for each study area separately by accounts. However, each account frequently
   includes equipment having more than one use. Also, equipment in one account
   frequently is associated closely with equipment in the same building in
   another account. Therefore, the separations procedures for central office
   equipment have been designed to deal with categories of plant rather than
   with equipment in an account.

   (c) In the separation of the cost of central office equipment among the
   operations, the first step is the assignment of the equipment in each study
   area  to categories. The basic method of making this assignment is the
   identification  of  the equipment assignable to each category, and the
   determination  of  the cost of the identified equipment by analysis of
   accounting, engineering and other records.

   (1) The cost of common equipment not assigned to a specific category, e.g.,
   common power equipment, including emergency power equipment, aisle lighting
   and framework, including distributing frames, is distributed among the
   categories  in  proportion  to the cost of equipment, (excluding power
   equipment not dependent upon common power equipment) directly assigned to
   categories.

   (i) The cost of power equipment used by one category is assigned directly to
   that category, e.g., 130 volt power supply provided for circuit equipment.
   The cost of emergency power equipment protecting only power equipment used
   by one category is also assigned directly to that category.

   (ii) Where appropriate, a weighting factor is applied to the cost of circuit
   equipment in distributing the power plant costs not directly assigned, in
   order to reflect the generally greater power use per dollar of cost of this
   equipment.

   (d) The second step is the apportionment of the cost of the equipment in
   each category among the operations through the application of appropriate
   use factors or by direct assignment.

§ 36.122   Categories and apportionment procedures.

   top

   (a) The following categories of central office equipment and apportionment
   procedures therefore are set forth in §§36.123 through 36.126.
   Operator Systems Equipment Category 1.
   Tandem Switching Equipment Category 2.
   Local Switching Equipment  Category 3.
   Circuit Equipment          Category 4.

§ 36.123   Operator systems equipment—Category 1.

   top

   (a) Operator systems equipment is contained in Account 2220. It includes all
   types of manual telephone switchboards except tandem switchboards and those
   used solely for recording of calling telephone numbers in connection with
   customer dialed charge traffic. It includes all face equipment, terminating
   relay circuits of trunk and toll line circuits, cord circuits, cable turning
   sections,  subscriber line equipment, associated toll connecting trunk
   equipment,  number  checking  facilities, ticket distributing systems,
   calculagraphs, chief operator and other desks, operator chairs, and other
   such equipment.

   (1)  Operator  systems  equipment is generally classified according to
   operating arrangements of which the following are typical:

   (i) Separate toll boards

   (ii) Separate local manual boards

   (iii) Combined local manual and toll boards

   (iv) Combined toll and DSA boards

   (v) Separate DSA and DSB boards

   (vi) Service observing boards

   (vii) Auxiliary service boards

   (viii) Traffic service positions

   (2) If switchboards as set forth in §36.123(a) are of the key pulsing type,
   the cost of the key pulsing senders, link and trunk finder equipment is
   included with the switchboards.

   (3) DSB boards include the associated DSB dial equipment, such as link and
   sender equipment.

   (4) Traffic service position systems include the common control and trunk
   equipment  in  addition to the associated groups of positions wherever
   located.

   (5) Effective July 1, 2001, through June 30, 2006, study areas subject to
   price cap regulation, pursuant to §61.41 of this chapter, shall assign the
   average   balance   of   Account   2220,   Operator  Systems,  to  the
   categories/subcategories,  as specified in §36.123(a)(1), based on the
   relative percentage assignment of the average balance of Account 2220 to
   these  categories/subcategories  during the twelve month period ending
   December 31, 2000.

   (6) Effective July 1, 2001 through June 30, 2006, all study areas shall
   apportion the costs assigned to the categories/subcategories, as specified
   in  §36.123(a)(1),  among  the  jurisdictions  using  the relative use
   measurements for the twelve month period ending December 31, 2000 for each
   of the categories/subcategories specified in §§36.123 (b) through 36.123(e).

   (b) The cost of the following operator systems equipment is apportioned
   among  the  operations on the basis of the relative number of weighted
   standard work seconds handled at the switchboards under consideration.

   (1)  The following types of switchboards at toll centers are generally
   apportioned individually:

   (i) Separate toll boards. These usually include outward, through and inward
   positions in separate lines and associated inward toll switchboard positions
   in line.

   (ii) Switchboards handling both local and toll, either combined or having
   segregated local and toll positions in the same line.

   (iii) Switchboards handling both toll and DSA, either combined or having
   segregated toll and DSA positions in the same line.

   (iv) Traffic service positions, including separately located groups of these
   positions when associated with a common basic control unit.

   (2) The following types of switchboards at toll centers are apportioned
   individually, or by groups of comparable types of boards for each exchange:

   (i) Separate local manual boards. This includes the local positions of
   manual boards where inward toll positions are in the same line.

   (ii) Separate DSA boards.

   (iii) Separate DSB boards.

   (3) Tributary boards may be treated individually if warranted or they may be
   treated on a group basis.

   (c) Auxiliary service boards generally handle rate and route, information,
   and intercept service at individual or joint positions. The cost of these
   boards is apportioned as follows:

   (1) The cost of separate directory assistance boards is apportioned among
   the operations on the basis of the relative number of weighted standard work
   seconds handled at the boards under consideration. Directory assistance
   weighted standard work seconds are apportioned among the operations on the
   basis of the classification of these weighted standard work seconds as
   follows:

   (i) Directory assistance weighted standard work seconds first are classified
   between calls received over toll directory assistance trunks from operators
   or customers and all other directory assistance calls.

   (ii) The directory assistance weighted standard work seconds of each type
   further are classified separately among the operations on the basis of an
   analysis of a representative sample of directory assistance calls of each
   type with reference to the locations of the calling and called stations for
   each call.

   (2) The cost of separate intercept boards and automated intercept systems in
   the study area is appportioned among the operations on the basis of the
   relative number of subscriber line minutes of use.

   (3) The cost of separate rate and route boards is generally included with
   the cost of the toll boards served and is apportioned with those boards.

   (4) Where more than one auxiliary service is handled at an auxiliary board,
   the cost of the board is apportioned among the auxiliary services on the
   basis of the relative number of weighted standard work seconds for each
   service. The cost of that part of the board allocated to each auxiliary
   service is apportioned among the operations in the same manner as for a
   separate auxiliary board.

   (d) The cost of joint exchange and toll service observing boards is first
   apportioned between exchange and toll use on the basis of the relative
   number of exchange and toll service observing units at these boards. The
   cost of separate toll service observing boards and the toll portion of joint
   service  observing  boards is apportioned between state and interstate
   operations  on the basis of the relative number of toll minutes of use
   associated with the toll messages originating in the offices observed.

   (e) Traffic Service Position System (TSPS) investments are apportioned as
   follows:

   (1)  Operator position investments are apportioned on the basis of the
   relative weighted standard work seconds for the entire TSPS complex.

   (2) Remote trunk arrangement (RTA) investments are apportioned on the basis
   of the relative processor real time (i.e., actual seconds) required to
   process TSPS traffic originating from the end offices served by each RTA.

   (3) The remaining investments at the central control location, such as the
   stored  program control and memory, is apportioned on the basis of the
   relative processor real time (i.e., actual seconds) for the entire TSPS
   complex.

§ 36.124   Tandem switching equipment—Category 2.

   top

   (a) Tandem switching equipment is contained in Accounts 2210, 2211, and
   2212.  It includes all switching equipment in a tandem central office,
   including any associated tandem switchboard positions and any intertoll
   switching  equipment. Intertoll switching equipment includes switching
   equipment used for the interconnection of message toll telephone circuits
   with each other or with local or tandem telephone central office trunks,
   intertoll dial selector equipment, or intertoll trunk equipment in No. 5
   type  electronic  offices.  Equipment, including switchboards used for
   recording of calling telephone numbers and other billing information in
   connection  with customer dialed charge traffic is included with Local
   Switching Equipment—Category 3.

   (1) At toll center toll offices, intertoll switching equipment comprises
   equipment in the toll office used in the interconnection of: Toll center to
   toll  center circuits; toll center to tributary circuits; tributary to
   tributary circuits; toll center to tandem circuits or in the interconnection
   of the aforementioned types of circuits with trunks to local offices in the
   toll center city, i.e., interconnection with toll switching trunks, operator
   trunks, information trunks, testing trunks, etc. Equipment associated with
   the  local  office end of such trunks is included with local switching
   equipment or switchboard categories as appropriate.

   (2)  At  tributary offices, this category includes intertoll switching
   equipment similar to that at toll center toll offices if it is used in the
   interconnection  of:  Tributary  to  tributary  circuits; tributary to
   subtributary circuits; subtributary to subtributary circuits; toll center to
   subtributary circuits; or if it is used jointly in the interconnection of
   any of the aforementioned types of circuits and in the interconnection of
   such  toll  circuits  with  trunk circuits for the handling of traffic
   terminating in the tributary office. Where comparable equipment has no joint
   use  but  is  used only for the handling of traffic terminating in the
   tributary office, it is included in the local switching equipment category.

   (3) At all switching entities, this category includes intertoll switching
   equipment similar to that at toll center toll offices if it is used in the
   interconnection of switched private line trunks or TWX switching plant
   trunks  when  these functions are in addition to the message telephone
   switching function. Switching entities wholly dedicated to switching of
   special services are assigned to Category 3—Local Switching Equipment.

   (b) The costs of central office equipment items assigned this category are
   to  be  directly assigned when possible. When direct assignment is not
   possible the costs shall be apportioned among the operations on the basis of
   the relative number of study area minutes of use of this equipment.

   (c) Effective July 1, 2001, through June 30, 2006, study areas subject to
   price cap regulation, pursuant to §61.41 of this chapter, shall assign the
   average balances of Accounts 2210, 2211, and 2212 to Category 2, Tandem
   Switching Equipment based on the relative percentage assignment of the
   average balances of Account 2210, 2211, 2212, and 2215 to Category 2, Tandem
   Switching Equipment during the twelve month period ending December 31, 2000.

   (d) Effective July 1, 2001, through June 30, 2006, all study areas shall
   apportion  costs  in Category 2, Tandem Switching Equipment, among the
   jurisdictions using the relative number of study area minutes of use, as
   specified in §36.124(b), for the twelve month period ending December 31,
   2000. Direct assignment of any subcategory of Category 2 Tandem Switching
   Equipment between jurisdictions shall be updated annually.

§ 36.125   Local switching equipment—Category 3.

   top

   (a) Local switching equipment is included in accounts 2210, 2211, and 2212.
   It comprises all central office switching equipment not assigned other
   categories. Examples of local switching equipment are basic switching train,
   toll  connecting  trunk  equipment,  interlocal trunks, tandem trunks,
   terminating senders used for toll completion, toll completing train, call
   reverting  equipment,  weather  and time of day service equipment, and
   switching equipment at electronic analog or digital remote line locations.
   Equipment used for the identification, recording and timing of customer
   dialed charge traffic, or switched private line traffic ( e.g. transmitters,
   recorders,  call identity indexers, perforators, ticketers, detectors,
   mastertimes) switchboards used solely for recording of calling telephone
   numbers in connection with customer dialed charge traffic, or switched
   private line traffic (or both) is included in this local switching category.
   Equipment provided and used primarily for operator dialed toll or customer
   dialed charge traffic except such equipment included in Category 2 Tandem
   Switching Equipment is also included in this local switching category. This
   includes such items as directors translators, sender registers, out trunk
   selectors and facilities for toll intercepting and digit absorption. Special
   services switching equipment which primarily performs the switching function
   for special services ( e.g. switching equipment, TWX concentrators and
   switchboards) is also included in this local switching category.

   (1) Local office, as used in §36.125, comprises one or more local switching
   entities of the same equipment type (e.g., step-by-step, No. 5 Crossbar) in
   an  individual location. A local switching entity comprises that local
   central office equipment of the same type which has a common intermediate
   distributing frame, market group or other separately identifiable switching
   unit serving one or more prefixes (NNX codes).

   (2) A host/remote local switching complex is composed of an electronic
   analog or digital host office and all of its remote locations. A host/remote
   local  switching  complex  is treated as one local office. The current
   jurisdictional definition of an exchange will apply.

   (3) Dial equipment minutes of use (DEM) is defined as the minutes of holding
   time of the originating and terminating local switching equipment. Holding
   time is defined in the Glossary.

   (4) The interstate allocation factor is the percentage of local switching
   investment apportioned to the interstate jurisdiction.

   (5) The interstate DEM factor is the ratio of the interstate DEM to the
   total DEM. A weighted interstate DEM factor is the product of multiplying a
   weighting  factor, as defined in paragraph (f) of this section, to the
   interstate DEM factor. The state DEM factor is the ratio of the state DEM to
   the total DEM.

   (b) Beginning January 1, 1993, Category 3 investment for study areas with
   50,000 or more access lines is apportioned to the interstate jurisdiction on
   the basis of the interstate DEM factor. Category 3 investment for study
   areas  with  50,000  or  more access lines is apportioned to the state
   jurisdiction on the basis of the state DEM factor.

   (c)–(e) [Reserved]

   (f) Beginning January 1, 1998, for study areas with fewer than 50,000 access
   lines, Category 3 investment is apportioned to the interstate jurisdiction
   by the application of an interstate allocation factor that is the lesser of
   either .85 or the sum of the interstate DEM factor specified in paragraph
   (a)(5) of this section, and the difference between the 1996 interstate DEM
   factor and the 1996 interstate DEM factor multiplied by a weighting factor
   as determined by the table below. The Category 3 investment that is not
   assigned  to the interstate jurisdiction pursuant to this paragraph is
   assigned to the state jurisdiction.
   Number of access lines in service in study area Weighting
   factor
   0–10,000 3.0
   10,001–20,000 2.5
   20,001–50,000 2.0
   50,001–or above 1.0

   (g) For purposes of this section, an access line is a line that does not
   include WATS access lines, special access lines or private lines.

   (h) Effective July 1, 2001, through June 30, 2006, study areas subject to
   price cap regulation, pursuant to §61.41 of this chapter, shall assign the
   average balances of Accounts 2210, 2211, and 2212 to Category 3, Local
   Switching Equipment, based on the relative percentage assignment of the
   average balances of Account 2210, 2211, 2212, and 2215 to Category 3, during
   the twelve month period ending December 31, 2000.

   (i) Effective July 1, 2001, through June 30, 2006, all study areas shall
   apportion  costs  in  Category 3, Local Switching Equipment, among the
   jurisdictions using relative dial equipment minutes of use for the twelve
   month period ending December 31, 2000.

   (j) If during the period from January 1, 1997, through June 30, 2006, the
   number of a study area's access lines increased or will increase such that,
   under §36.125(f) the weighting factor would be reduced, that lower weighting
   factor shall be applied to the study area's 1996 unweighted interstate DEM
   factor to derive a new local switching support factor. The study area will
   restate its Category 3, Local Switching Equipment factor under §36.125(f)
   and use that factor for the duration of the freeze period.

   the purpose of identifying and separating property associated with special
   services, circuit equipment included in Categories 4.12 (other than wideband
   equipment) 4.13 and 4.23 is identified as either basic circuit equipment,
   i.e., equipment that performs functions necessary to provide and operate
   channels suitable for voice transmission (telephone grade channels), or
   special circuit equipment, i.e., equipment that is peculiar to special
   service  circuits.  Carrier  telephone terminals and carrier telephone
   repeaters are examples of basic circuit equipment is general use, while
   audio program transmission amplifiers, bridges, monitoring devices and
   volume indicators, telegraph carrier terminals and telegraph repeaters are
   examples of special circuit equipment in general use. Cost of exchange
   circuit equipment included in Categories 4.12 and 4.13 and the interexchange
   circuit equipment in Categories 4.21, 4.22 and 4.23 are segregated between
   basic  circuit  equipment  and special circuit equipment only at those
   locations  where amounts of interexchange and exchange special circuit
   equipment are significant. Where such segregation is not made, the total
   costs in these categories are classified as basic circuit equipment.

   (5) Effective July 1, 2001, through June 30, 2006, study areas subject to
   price cap regulation, pursuant to §61.41, shall assign the average balances
   of Accounts 2230 through 2232 to the categories/subcategories as specified

Cable and Wire Facilities

   top

§ 36.151   General.

   top

   (a) Cable and Wire Facilities, Account 2410, includes the following types of
   communications plant in service: Poles and antenna supporting structures,
   aerial cable, underground cable, buried cable, submarine cable, deep sea
   cable, intrabuilding network cable, aerial wire and conduit systems.

   (b) For separations purposes, it is necessary to analyze the cable and wire
   facilities classified in subordinate records in order to determine their
   assignment to the categories listed in the following paragraphs.

   (c) In the separation of the cost of cable and wire facilities among the
   operations, the first step is the assignment of the facilities to certain
   categories. The basic method of making this assignment is the identification
   of the facilities assignable to each category and the determination of the
   cost of the facilities so identified. Because of variations among companies
   in the character of the facilities and operating conditions, and in the
   accounting  and  engineering  records maintained, the detailed methods
   followed,  of  necessity,  will  vary among the companies. The general
   principles to be followed, however, will be the same for all companies.

   (d) The second step is the apportionment of the cost of the facilities in
   each category among the operations through the application of appropriate
   factors or by direct assignment.

§ 36.152   Categories of Cable and Wire Facilities (C&WF).

   top

   (a) C&WF are basically divided between exchange and interexchange. Exchange
   C&WF consists of the following categories:

   (1) Exchange Line C&WF Excluding Wideband —Category 1—This category includes
   C&W facilities between local central offices and subscriber premises used
   for  message telephone, private line, local channels, and for circuits
   between control terminals and radio stations providing very high frequency
   maritime service or urban or highway mobile service.

   (2) Wideband and Exchange Trunk C&WF—Category 2—This category includes all
   wideband, including Exchange Line Wideband and C&WF between local central
   offices and Wideband facilities. It also includes C&WF between central
   offices or other switching points used by any common carrier for interlocal
   trunks wholly within an exchange or metropolitan service area, interlocal
   trunks  with one or both terminals outside a metropolitan service area
   carrying  some exchange traffic, toll connecting trunks, tandem trunks
   principally carrying exchange traffic, the exchange trunk portion of WATS
   access lines, the exchange trunk portion of private line local channels, and
   the exchange trunk portion of circuits between control terminals and radio
   stations providing very high frequency maritime service or urban or highway
   mobile service.

   (3) The procedures for apportioning the cost of exchange cable and wire
   facilites among the operations are set forth in §§36.154 and 36.155.

   (b) Interexchange C&WF—Category 3—This category includes the C&WF used for
   message toll and toll private line services. It includes cable and wire
   facilities   carrying  intertoll  circuits,  tributary  circuits,  the
   interexchange channel portion of special service circuits, circuits between
   control terminals and radio stations used for overseas or coastal harbor
   service, interlocal trunks between offices in the different exchange or
   metropolitan service areas carrying only message toll traffic and certain
   tandem trunks which carry principally message toll traffic.

   (1) The procedures for apportioning the cost of interexchange cable and wire
   facilities among the operations are set forth in §36.156.

   (c) Host/Remote Message C&WF—Category 4—This category includes the cost of
   message host/remote location C&WF for which a message circuit switching
   function is performed at the host central office. It applies to C&WF between
   host offices and all remote locations. The procedures for apportioning the
   cost of these facilities among the operations are set forth in §36.157.

   (d) Effective July 1, 2001, through June 30, 2006, study areas subject to
   price cap regulation, pursuant to §61.41, shall assign the average balance
   of Account 2410 to the categories/subcategories, as specified in §§36.152(a)
   through (c), based on the relative percentage assignment of the average
   balance of Account 2410 to these categories/subcategories during the twelve
   month period ending December 31, 2000.

§ 36.153   Assignment of Cable and Wire Facilities (C&WF) to categories.

   top

   (a)  Cable consists of: Aerial cable, underground cable, buried cable,
   submarine cable, deep sea cable and intrabuilding network cable. Where an
   entire cable or aerial wire is assignable to one category, its cost and
   quantity are, where practicable, directly assigned.

   (1) Cable. (i) There are two basic methods for assigning the cost of cable
   to the various categories. Both of them are on the basis of conductor cross
   section. The methods are as follows:

   (A)  By  section  of  cable,  uniform as to makeup and relative use by
   categories. From an analysis of cable engineering and assignment records,
   determine  in  terms of equivalent gauge the number of pairs in use or
   reserved,  for each category. The corresponding percentages of use, or
   reservation, are applied to the cost of the section of cable, i.e., sheath
   meters times unit cost per meter, to obtain the cost assignable to each
   category.

   (B) By using equivalent pair kilometers, i.e., pair kilometers expressed in
   terms  of  equivalent gauge. From an analysis of cable engineering and
   assignment records, determine the equivalent pair kilometers in use for each
   category by type of facility, e.g., quadded, paired. The equivalent pair
   kilometers are then divided by a cable fill factor to obtain the equivalent
   pair kilometers in plant. The total equivalent pair kilometers in plant
   assigned to each category is summarized by type of facility, e.g., quadded
   and paired, and priced at appropriate average unit costs per equivalent pair
   kilometer in plant. If desired, this study may be made in terms of circuit
   kilometers rather than physical pair kilometers, with average cost and fill
   data consistent with the basis of the facilities kilometer count.

   (ii) In the assignment of the cost of cable under the two basic methods
   described in §36.153(a)(1)(i) consideration is given to the following:

   (A) Method (A) described in §36.153(a)(1)(i)(A) will probably be found more
   desirable where there is a relatively small amount of cable of variable
   make-up  and  use  by  categories. Conversely, method (B) described in
   §36.153(a)(1)(i)(B) will probably be more desirable where there is a large
   amount of cable of variable make-up and use by categories. However, in some
   cases a combination of both methods may be desirable.

   (B) It will be desirable in some cases to determine the amount assignable to
   a particular category by deducting from the total the sum of the amounts
   assigned to all other categories.

   (C) For use in the assignment of poles to categories, the equivalent sheath
   kilometers of aerial cable assigned to each category are determined. For
   convenience, these quantities are determined in connection with assignment
   of cable costs.

   (D) Where an entire cable is assignable to one category, its costs and
   quantity are, where practicable, directly assigned.

   (iii) For cables especially arranged for high-frequency transmission such as
   shielded, disc-insulated and coaxial, recognition is given to the additional
   costs which are charged to the high-frequency complement.

   (2) Cable Loading. (i) Methods for assigning the cost of loading coils,
   cases, etc., to categories are comparable with those used in assigning the
   associated cable to categories. Loading associated with cable which is
   directly  assigned  to a given category is also directly assigned. The
   remaining loading is assigned to categories in either of the following
   bases:

   (A) By an analysis of the use made of the loading facilities where a loading
   coil case includes coils assignable to more than one category, e.g., in the
   case of a single gauge uniformly loaded section, the percentage used in the
   related cable assignment are applicable, or

   (B) By pricing out each category by determining the pair meters of loaded
   pairs assigned to each category and multiplying by the unit cost per pair
   meter of loading by type.

   (3) Other Cable Plant. (i) In view of the small amounts involved, the cost
   of all protected terminals and gas pressure contactor terminals in the toll
   cable subaccounts is assigned to the appropriate Interexchange Cable & Wire
   Facilities categories. The cost of all other terminals in the exchange and
   toll cable subaccounts is assigned to Exchange Cable and Wire Facilities.

   (b) Aerial Wire. (1) The cost of wire accounted for as exchange is assigned
   to the appropriate Exchange Cable & Wire Facilities categories. The cost of
   wire accounted for as toll, which is used for exchange, is also assigned to
   the appropriate Exchange Cable & Wire Facilities categories. The cost of the
   remaining  wire  accounted  for as toll is assigned to the appropriate
   Interexchange Cable & Wire Facilities categories as described in §36.156.
   For companies not maintaining exchange and toll subaccounts, it is necessary
   to review the plant records and identify wire plant by use. The cost of wire
   used for providing circuits directly assignable to a category is assigned to
   that  category. The cost of wire used for providing circuit facilities
   jointly used for exchange and interexchange lines is assigned to categories
   on the basis of the relative number of circuit kilometers involved.

   (c) Poles and Antenna Supporting Structures. (1) In the assignment of these
   costs,  anchors,  guys,  crossarms,  antenna supporting structure, and
   right-of-way are included with the poles.

   (2) Poles. (i) The cost of poles is assigned to categories based on the
   ratio of the cost of poles to the total cost of aerial wire and aerial
   cable.

   (d)  Conduit  Systems.  (1) The cost of conduit systems is assigned to
   categories on the basis of the assignment of the cost of underground cable.

   (a) Exchange Line C&WF—Category 1. The first step in apportioning the cost
   of exchange line cable and wire facilities among the operations is the
   determination of an average cost per working loop. This average cost per
   working loop is determined by dividing the total cost of exchange line cable
   and  wire Category 1 in the study area by the sum of the working loops
   described in subcategories listed below. The subcategories are:

   Subcategory 1.1—State Private Lines and State WATS Lines. This subcategory
   shall include all private lines and WATS lines carrying exclusively state
   traffic as well as private lines and WATS lines carrying both state and
   interstate  traffic  if  the  interstate  traffic on the line involved
   constitutes ten percent or less of the total traffic on the line.

   Subcategory 1.2—Interstate private lines and interstate WATS lines. This
   subcategory  shall include all private lines and WATS lines that carry
   exclusively interstate traffic as well as private lines and WATS lines
   carrying both state and interstate traffic if the interstate traffic on the
   line involved constitutes more than ten percent of the total traffic on the
   line.

   Subcategory 1.3—Subscriber or common lines that are jointly used for local
   exchange service and exchange access for state and interstate interexchange
   services.

   into two groups as follows: (1) Operating Federal, State and local income
   taxes and (2) all other operating taxes.

   (b) Operating Federal, State and local income taxes are apportioned among
   the operations on the basis of the approximate net taxable income (positive
   or negative) applicable to each of the operations. The approximate net
   taxable income from each of the operations is the summation of the following
   amounts apportioned to each operation by means of the procedures set forth
   in this Manual:

   (1) Operating revenues,

   (2) Less operating expenses,

   (3) Less operating taxes except the net income tax being apportioned and
   except any other tax not treated as a deductible item in the determination
   of taxable net income for this purpose.

   (4) Less operating fixed charges.

   (i) The amount of fixed charges attributable to the operations is obtained
   by subtracting the tax component (positive or negative) attributable to
   other than the operating fixed charges, i.e., fixed charges on non-operating
   investments are that proportion of total fixed charges which non-operating
   net investments are of total operating and non-operating net investments.

   (ii) Operating fixed charges including interest on Rural Telephone Bank
   Stock are apportioned among the operations on the basis of the separation of
   the cost of telephone plant less appropriate reserves.

   (c) Other operating taxes should be directly assigned to the appropriate
   jurisdiction where possible, e.g., Local Gross Receipts may be directly
   identified as applicable to one jurisdiction. Where direct assignment is not
   feasible, these expenses should be apportioned among the operations on the
   basis  of  the  separation  of the cost of Telecommunications Plant in
   Service—Account 2001.

Equal Access Expenses

§ 36.421   Equal access expenses.

   top

   (a) Equal access expenses include only initial incremental pre-subscription
   costs and other initial incremental expenditures related directly to the
   provision  of  equal access, that would not be required to upgrade the
   capabilities of the office involved absent the provision of equal access.
   Equal  access expenses are limited to such expenditures for converting
   central offices that serve competitive interexchange carriers or where there
   has been a bona fide request for conversion to equal access.

   (b) Equal access expenses are apportioned between the jurisdictions by first
   segregating them from all other expenses in the primary accounts and then
   allocating them on the same basis as equal access investment.

§ 36.601   General.

   top

   (a) The term Universal Service Fund in this subpart refers only to the
   support for loop-related costs included in §36.621. The term Universal
   Service in part 54 of this chapter refers to the comprehensive discussion of
   the Commission's rules implementing section 254 of the Communications Act of
   1934, as amended, 47 U.S.C. 254, which addresses universal service support
   for rural, insular, and high cost areas, low-income consumers, schools and
   libraries, and heath care providers. The expense adjustment calculated
   pursuant  to  this subpart F shall be added to interstate expenses and
   deducted from state expenses after expenses and taxes have been apportioned
   pursuant to subpart D of this part. Beginning January 1, 1998, the expense
   adjustment calculated pursuant to this subpart will be administered and
   funded through the new universal service system discussed in part 54 of this
   chapter.

   (b) The expense adjustment will be computed on the basis of data for a
   preceding calendar year which may be updated at the option of the carrier
   pursuant to §36.612(a).

   (c) Until June 30, 2001, the annual amount of the total nationwide expense
   adjustment shall consist of the amounts calculated pursuant to §54.309 of
   this chapter and the amounts calculated pursuant to this subpart F. The
   annual  amount  of  the  total nationwide loop cost expense adjustment
   calculated pursuant to this subpart F shall not exceed the amount of the
   total loop cost expense adjustment for the immediately preceding calendar
   year, increased by a rate equal to the rate of increase in the total number
   of working loops during the calendar year preceding the July 31st filing.
   The  total loop cost expense adjustment shall consist of the loop cost
   expense adjustments, including amounts calculated pursuant to §36.612(a) and
   §36.631. The rate of increase in total working loops shall be based upon the
   difference between the number of total working loops on December 31 of the
   calendar year preceding the July 31st filing and the number of total working
   loops on December 31 of the second calendar year preceding that filing, both
   determined by the company's submissions pursuant to §36.611. Beginning
   January 1, 2000, non-rural incumbent local exchange carriers and, eligible
   telecommunications carriers serving lines in the service area of non-rural
   incumbent local exchange carriers, shall only receive support pursuant to
   this subpart F to the extent that they qualify pursuant to §54.311 of this
   chapter  for interim hold-harmless support. Support amounts calculated
   pursuant to this subpart F but not received due to the phase down of interim
   hold-harmless support or the receipt of forward-looking support pursuant to
   §54.311 of this chapter shall not be redistributed to other carriers.

   (a) Effective July 1, 2001, the rural incumbent local exchange carrier
   portion  of the annual nationwide loop cost expense adjustment will be
   recomputed  by the fund administrator as if the indexed cap calculated
   pursuant to §36.601(c) and the corporate operations expense limitation
   calculated pursuant to §36.621 had not been in effect for the calendar year
   2000. For the period July 1, 2001, to December 31, 2001, the annualized
   amount  of  the  rural incumbent local exchange carrier portion of the
   nationwide loop cost expense adjustment calculated pursuant to this subpart
   F shall not exceed the non-capped amount of the total rural incumbent local
   exchange carrier loop cost expense adjustment for the calendar year 2000,

   nationwide loop cost expense adjustment calculated pursuant to this subpart
   F shall not exceed the non-capped amount of the total rural incumbent local
   exchange  carrier loop cost expense adjustment for calendar year 2000,
   multiplied times one plus the Rural Growth Factor for 2001, which then shall
   be multiplied times one plus the Rural Growth Factor for 2002. Beginning
   January 1, 2003, the annual amount of the rural incumbent local exchange
   carrier portion of the nationwide loop cost expense adjustment calculated
   pursuant to this subpart F shall not exceed the amount of the total rural
   incumbent  local exchange carrier loop cost expense adjustment for the
   immediately preceding calendar year, multiplied times one plus the Rural
   Growth Factor calculated pursuant to §36.604.

   (b)  The  annual rural incumbent local exchange carrier portion of the

§ 36.605   Calculation of safety net additive.

   top

   (a) “Safety net additive support.” A rural incumbent local exchange carrier
   shall receive safety net additive support if it satisfies the conditions set
   forth in paragraph (c) of this section. Safety net additive support is
   support available to rural telephone companies, as conditioned in paragraph
   (c) of this section, in addition to support calculated pursuant to §36.631.
   Safety  net additive support shall not be available to rural telephone
   companies for exchange(s) that are subject to §54.305 of this chapter.

   (b) Calculation of safety net additive support: Safety net additive support
   is equal to the amount of capped support calculated pursuant to this subpart
   F in the qualifying year minus the amount of support in the year prior to
   qualifying for support subtracted from the difference between the uncapped
   expense adjustment for the study area in the qualifying year minus the
   uncapped expense adjustment in the year prior to qualifying for support as
   shown in the following equation: Safety net additive support = (Uncapped
   support in the qualifying year−Uncapped support in the base year)−(Capped
   support in the qualifying year−Amount of support received in the base year).

   (c) Operation of safety net additive support: (1) In any year in which the
   total carrier loop cost expense adjustment is limited by the provisions of
   §36.603 a rural incumbent local exchange carrier shall receive safety net
   additive support as calculated in paragraph (b) of this section, if in any
   study area, the rural incumbent local exchange carrier realizes growth in
   end of period Telecommunications Plant in Service (TPIS), as prescribed in
   §32.2001 of this chapter, on a per loop basis, of at least 14 percent more
   than the study area's TPIS per loop investment at the end of the prior
   period.

   (2) If paragraph (c)(1) of this section is met, the rural incumbent local
   exchange carrier must notify the Administrator; failure to properly notify
   the Administrator of eligibility shall result in disqualification of that
   study area for safety net additive, requiring the rural incumbent local
   exchange carrier to again meet the eligibility requirements in paragraph
   (c)(1) of this section for that study area in a subsequent period.

   (3) Upon completion of verification by the Administrator that the study area
   meets the stated criterion in paragraphs (a), (b), (c) of this section, the
   Administrator shall:

   (i) Pay to any qualifying rural telephone company, safety net additive
   support for the qualifying study area in accordance with the calculation set
   forth in paragraph (b) of this section; and

   (ii)  Continue  to  pay safety net additive support in any of the four
   succeeding years in which the total carrier loop expense adjustment is
   limited by the provisions of §36.603. Safety net additive support in the
   succeeding four years shall be the lesser of:

   (A) The sum of capped support and the safety net additive support received
   in the qualifying year; or

   (B) The rural telephone company's uncapped support.

   (a) For the purpose of calculating the expense adjustment, the study area
   total unseparated loop cost equals the sum of the following:

   (1) Return component for net unseparated Exchange Line C&WF subcategory 1.3
   investment and Exchange Line CO Circuit Equipment Category 4.13 investment.
   This amount is calculated by deducting the accumulated depreciation and
   noncurrent deferred Federal income taxes attributable to C&WF subcategory
   1.3 investment and Exchange Line Category 4.13 circuit investment reported
   pursuant to §36.611(b) from the gross investment in Exchange Line C&WF
   subcategory 1.3 and CO Category 4.13 reported pursuant to §36.611(a) to
   obtain the net unseparated C&WF subcategory 1.3 investment, and CO Category
   4.13 investment. The net unseparated C&WF subcategory 1.3 investment and CO
   Category  4.13 investment is multiplied by the study area's authorized
   interstate rate of return.

   (2) Depreciation expense attributable to C&WF subcategory 1.3 investment,
   and CO Category 4.13 investment as reported in §36.611(c).

   (3) Maintenance expense attributable to C&WF subcategory 1.3 investment, and
   CO Category 4.13 investment as reported in §36.611(d).

   (4) Corporate Operations Expenses, Operating Taxes and the benefits and rent
   portions of operating expenses, as reported in §36.611(e) attributable to
   investment  in C&WF Category 1.3 and COE Category 4.13. This amount is
   calculated by multiplying the total amount of these expenses and taxes by
   the  ratio  of the unseparated gross exchange plant investment in C&WF
   Category  1.3 and COE Category 4.13, as reported in §36.611(a), to the
   unseparated  gross telecommunications plant investment, as reported in
   §36.611(f). Total Corporate Operations Expense, for purposes of calculating
   universal service support payments beginning July 1, 2001, shall be limited

   (a)(4)(ii)(A), (a)(4)(ii)(B), (a)(4)(ii)(C), and (a)(4)(ii)(D) of this
   section. To the extent that some carriers' corporate operations expenses are
   disallowed pursuant to these limitations, the national average unseparated
   cost per loop shall be adjusted accordingly.

   (A) For study areas with 6,000 or fewer working loops the amount monthly per
   working loop shall be $33.30853−(.00246 × the number of working loops), or,
   $50,000 ÷ the number of working loops, whichever is greater;

   (B) For study areas with more than 6,000 but fewer than 18,006 working
   loops, the monthly amount per working loop shall be $3.83195 + (88,429.20 ÷
   the number of working loops); and

   (C) For study areas with 18,006 or more working loops, the monthly amount
   per working loop shall be $8.74472.

   §36.621(a) divided by the sum of the working loops reported in §36.611(h)
   for each study area in the country. The national average unseparated loop
   cost per working loop shall be calculated by the National Exchange Carrier
   Association. Effective July 1, 2001, the national average unseparated loop
   cost for purposes of calculating expense adjustments for rural incumbent
   local exchange carriers, as that term is defined in §54.5 of this chapter,
   is frozen at $240.00.

   (1) The National Average Unseparated Loop Cost per Working Loop shall be
   recalculated by the National Exchange Carrier Association to reflect the
   September, December, and March update filings.

   (2) Each new nationwide average shall be used in determining the additional
   interstate expense allocation for companies which made filings by the most
   recent filing date.

   (3) The calculation of a new national average to reflect the update filings
   shall not affect the amount of the additional interstate expense allocation
   for companies which did not make an update filing by the most recent filing
   date.

   (b) Study Area Average Unseparated Loop Cost per Working Loop. This is equal
   to the unseparated loop costs for the study area as calculated pursuant to
   §36.621(a) divided by the number of working loops reported in §36.611(h) for
   the study area.

   (1) If a company elects to, or is required to, update the data which it has
   filed  with  the  National Exchange Carrier Association as provided in
   §36.612(a), the study area average unseparated loop cost per working loop
   and the amount of its additional interstate expense allocation shall be
   recalculated to reflect the updated data.

   (2) [Reserved]

   (c) The National Average Unseparated Loop Cost per Working Loop shall be the
   greater of:

   (1) The amount calculated pursuant to the method described in paragraph (a)
   of this section; or

   (2) Until June 30, 2001, an amount calculated to produce the maximum total
   Universal Service Fund allowable pursuant to §36.601(c). Effective July 1,
   2001, for non-rural carriers, an amount calculated to produce the maximum
   non-rural  carrier  portion of nationwide loop cost expense adjustment
   allowable pursuant to §36.602. Effective July 1, 2001, for rural carriers,

   working loop as calculated pursuant to §36.622(b) in excess of 250 percent
   of the national average for this cost as calculated pursuant to §36.622(a)
   multiplied by the number of working loops reported in §36.611(h) for the
   study area.

   (e) Beginning April 1, 1989, the expense adjustment calculated pursuant to
   §36.631 (c) and (d) shall be adjusted each year to reflect changes in the
   size of the Universal Service Fund resulting from adjustments calculated
   pursuant to §36.612(a) made during the previous year. If the resulting
   amount exceeds the previous year's fund size, the difference will be added
   to the amount calculated pursuant to §36.631 (c) and (d) for the following
   year. If the adjustments made during the previous year result in a decrease
   in the size of the funding requirement, the difference will be subtracted
   from the amount calculated pursuant to §36.631 (c) and (d) for the following
   year.
