EXECUTIVE SUMMARY 1. On April 2, 1993, local exchange companies (LECs) filed their 1993 annual access tariffs, with an effective date of July 1, 1993. The Common Carrier Bureau (Bureau) suspended in part the 1993 annual access rates for one day, imposed an accounting order, and initiated an investigation of the tariffs to resolve a number of issues. On April 2, 1994, the LECs filed their 1994 annual access tariffs, with an effective date of July 1, 1994, and on May 9, 1995, their 1995 annual access tariffs, with an effective date of August 1, 1995. On April 2, 1996, the LECs filed their 1996 annual access tariffs, with an effective date of July 1, 1996. The Bureau suspended in part the tariff revisions for the 1994 through 1996 tariffs filings and made them subject to the 1993 tariff investigation and the accounting order instituted in CC Docket No. 93-193. 2. This Order resolves the Bureau's investigation with respect to most of the issues designated for investigation in the 1993 Annual Access Order in CC Docket No. 93-193 and several of the issues raised by the 1994, 1995, and 1996 annual access filings that were made subject to that investigation. This Order also denies an application for review filed by AT&T that claims that the Bureau, in the 1994 Annual Access Orders, erred by failing to suspend and investigate the LECs' 1994 annual access tariff filings because the LECs did not reduce their price cap indices (PCIs) to reflect the full amortization of their equal access expenses as an exogenous cost change. Finally, this Order grants in part and dismisses in part a petition filed by Southwestern of the First 1994 Annual Access Order requesting that the Commission"clarify or reconsider that part of its [Order] that implies that local exchange carriers (LECs) subject to price cap regulation and wishing to treat the new [Commission] regulatory fees as exogenous costs should petition for a waiver of the Commission's rules" and "clarify that [Southwestern's] proposed $6.04 fixed mileage charge for DS1 services with zero miles of interoffice transport is not subject to the expanded interconnection investigation." 3. In the 1993 Annual Access Order, the Bureau designated the following issues for investigation: (1) whether US West's method of calculating its exogenous cost adjustment associated with a change in the prescribed method of allocating local switching equipment costs complies with Section 61.45(d) of the Commission's rules; (2) whether Bell Atlantic and SNET correctly calculated the growth factor ("g" factor) used to establish the PCI for the common line basket; (3) whether Bell Atlantic should be permitted to exclude end user charge revenues from the common line basket for purposes of allocating its sharing obligations; (4) whether the LECs have properly reallocated general support facility (GSF) costs in accordance with the GSF Order; (5) whether LECs have assigned to the proper category or categories the line information data base (LIDB) per query charges; and (6) whether Roseville, a rate-of-return regulated company, has justified its cash working capital requirement and underlying study in support of its annual access rates. On July 27, 1993, the LECs filed their direct cases in response to the 1993 Annual Access Order and, on August 24, 1993, filed their comments. 4. While the 1993 access tariff investigation was open, the LECs filed their 1994, 1995, and 1996 annual access tariffs which generally followed the same costing and ratesetting methodologies used in the 1993 access tariff filings set for investigation. In the First 1994 Annual Access Order, the Price Cap Carriers' 1995 Annual Access Order, and the 1996 Annual Access Order, the Bureau suspended for one day Bell Atlantic's tariff revisions regarding the calculation of the "g" factor and made those tariff revisions subject to the investigation of Bell Atlantic's "g" factor calculation in CC Docket No. 93-193. In the 1994 Annual Access Orders, the Price Cap Carriers' 1995 Annual Access Order, and the 1996 Annual Access Order, the Bureau suspended for one day Bell Atlantic's and Pacific Bell's tariff revisions that reflected the exclusion of end user charge revenues from the common line basket for purposes of allocating their sharing obligations and made those tariff revisions subject to the investigation of those issues in the 1993 access tariff investigation. In addition, the 1994 Annual Access Orders rejected proposals advanced by AT&T and MCI to treat the expiration of equal access cost amortization exogenously. Further, the 1994 Annual Access Orders held that certain carriers' proposals to treat Commission regulatory fees as exogenous costs in their tariff filings violated the price cap rules and stated that, absent a rulemaking, the only way to obtain exogenous treatment for these fees is through a waiver of the Commission's rules. Finally, in the First 1994 Annual Access Order, the Bureau held that Southwestern's proposed fixed mileage charge for DS1 services with zero miles of interoffice transport raised sufficient risk of double recovery to warrant an investigation and incorporated this issue into the Commission's ongoing expanded interconnection investigation. 5. In this Order, we reach the following conclusions with respect to issues designated for investigation in CC Docket No. 93-193. First, we conclude that, in its 1993 annual access tariff filing, US West's method of calculating the exogenous cost change associated with the change in the method of allocating local switching equipment costs is incorrect. Second, we find that Bell Atlantic, in its 1993, 1994, 1995, and 1996 annual access filings, and SNET, in its 1993 annual access filings, have incorrectly calculated the "g" factor used to establish the common line PCI. Third, we find that Bell Atlantic and Pacific Bell incorrectly excluded end user charge revenues for purposes of allocating sharing obligations among price cap baskets. Fourth, we find the GSF tariff filings of most carriers to be consistent with the GSF Order but conclude that there may have been a double recovery of a portion of GSF costs by carriers that participated in NECA's common line tariff but filed individual tariffs for traffic sensitive rates pursuant to Section 61.39. Fifth, we determine that the LIDB per query charge should be assigned to the data base access services category within the traffic sensitive basket. Sixth, we find that Roseville has not adequately justified its cash working capital calculations. 6. In this Order, we also deny AT&T's application for review and affirm the Bureau's decision that the completion of the eight-year amortization of equal access costs may not be treated as an exogenous cost event. In addition, we dismiss in part and grant in part Southwestern's petition for clarification or reconsideration of the Bureau's decisions in the First 1994 Annual Access Order regarding exogenous treatment of regulatory fees and Southwestern's DS1 zero mileage charge. 7. In this Order, we direct the price cap LECs whose annual access tariff filings are in violation of the Commission's rules and determinations herein to recalculate their PCIs, pricing bands and maximum carrier common line rates. We decide how these recalculations should be done and what remedies should apply for violation of our rules. In addition, we require Roseville, a rate-of-return regulated company, to refund the amount attributable to the miscalculation of its cash working capital allowance and to submit its calculations of this refund amount and a refund plan to the Bureau. We also require the carriers that participated in NECA's common line pool and filed individual tariffs for traffic sensitive rates pursuant to Section 61.39 to provide explanations of their GSF allocations and revisions to traffic sensitive rates and if necessary, to submit a plan for any corrective action to eliminate any double recovery of GSF costs. II. INVESTIGATION ISSUES A. Background 8. In its price cap decisions, the Commission replaced rate-of-return regulation with an incentives-based system of regulation that rewards companies that become more productive and efficient, while ensuring that they share productivity and efficiency gains with their ratepayers. The theory of price caps is to harness the profit-making incentives common to all businesses to produce a set of outcomes that advance the public interest goals of just, reasonable, and nondiscriminatory rates, as well as a nation-wide communications system that offers innovative, high quality services. 9. Under the LEC price cap plan, a carrier's interstate services are grouped into baskets. Under the Commission's initial price cap plan, the four services baskets were the common line, traffic sensitive, special access, and interexchange services baskets. For each basket, a PCI limits the prices carriers charge for services in that basket. The PCI is adjusted each year based on a formula that includes a measure of inflation which is offset by a "productivity" factor or "X-Factor." The X-Factor reflects the fact that changes in telephone companies' costs per unit of output (unit costs) have historically been below that of the economy as a whole due to greater productivity gains and lower input price changes enjoyed by the telecommunications sector. Carriers that are able to generate productivity gains in excess of the X-Factor they elect are allowed to keep at least a portion of earnings higher than those experienced under rate-of-return regulation. Carriers also benefit because price cap regulation gives them increased flexibility in setting rates and is simpler to administer. Ratepayers benefit because the price cap rules encourage greater efficiency and reduced rates by requiring LECs to out-perform historical trends. Generally, changes in costs are not relevant to price cap regulation and carriers must control their costs if they are to remain profitable. Through these incentives, ratepayers receive the benefits of improved efficiency and reduced rates. 10. Although changes in a carrier's costs are not generally relevant for rate making under the price cap system, the Commission determined in the LEC Price Cap Order that certain costs incurred by LECs caused by administrative, legislative, or judicial requirements beyond their control should result in an adjustment to their PCIs. The Commission found that not recognizing these costs in the PCIs would either unjustly punish or reward the carrier by attributing these uncontrollable changes to the carrier's efficiency. The Commission designated those changes in costs for which an adjustment in the PCI would be allowed as "exogenous." The Commission, however, determined that not all changes that lie beyond the carrier's control warrant exogenous treatment. For example, the Commission noted that, although a change in tax rates applicable to all companies is beyond the carrier's control, that change will be captured in the general inflation component of the price cap formula. Exogenous treatment of this kind of tax change would "double count" its impact, once in the inflation measure, and again as an exogenous cost change. The Commission decided that only those tax changes that "uniquely or disproportionately" affect the LECs would be eligible for exogenous treatment. Similarly, although a carrier cannot control changes in generally accepted accounting principles (GAAP), the Commission stated that "[i]f a GAAP change is universal enough to be reflected in the inflation measure, exogenous cost treatment would result in double counting within the context of the PCI." Therefore, we decided to accord exogenous treatment to costs associated with GAAP changes that have been adopted by the Financial Accounting Standards Board, have become effective, and are shown not to be reflected already in changes to the GNP-PI. 11. Exogenous cost changes specified in our rules include cost changes that result from: (1) completing the amortization of depreciation reserve deficiencies; (2) amendments to the Uniform System of Accounts (USOA) as the Commission shall permit or require; (3) changes in the Separations Manual; (4) reallocation of regulated investment to nonregulated activities; (5) changes in transitional and long term support; (6) inside wire amortizations; and (7) tax law changes and other "extraordinary" changes to the extent we may permit or require. The Commission has declined to extend or has explicitly rejected exogenous treatment for other cost categories, including depreciation rate changes and amortization of equal access costs. 12. Within certain price cap baskets, services are grouped into service categories and subcategories and rate changes within the categories and subcategories are limited by upper and lower pricing bands. Before the Commission adopted the LEC Performance Review, the pricing band limits for most of the service categories and subcategories were set at 5 percent above and below a subindex of the prices for each category or subcategory (called the Service Band Index (SBI)), as adjusted by the change in the PCI for the basket. A presumption of lawfulness and a relatively short tariff filing notice period apply to rate changes that conform to the limits set by a LEC's PCIs and pricing bands. Substantial cost justification and longer tariff filing notice periods are required if rates exceed the price cap for a basket or are above or below the applicable pricing bands for a service category or subcategory. B. US West Exogenous Impact of Dial Equipment Minutes Transition 1. Background 13. Part 36 of the Commission's jurisdictional separations rules allocates investment costs of local switching equipment between the interstate and intrastate jurisdictions by the use of Dial Equipment Minutes (DEM). Dial equipment minutes are the minutes of holding time of the originating and terminating local dial switching equipment (i.e., the time local switching equipment is in actual use either by a customer or an operator), and the DEM factor for allocating local switching equipment costs to interstate service is the ratio (expressed as a percentage) of interstate minutes of use to the total minutes of use. 14. Before 1988, local switching equipment costs were allocated between the state and federal jurisdictions through a two-step process. First, switch costs were categorized as traffic sensitive or non-traffic sensitive. How costs were categorized depended upon the type of switch (digital or analog). Non-traffic sensitive costs were allocated to the interstate jurisdiction based on the interstate subscriber plant factor (SPF); traffic sensitive portions were allocated based on the DEM factor. The Commission then changed this rule to require that the DEM factor alone be used to divide all local switching equipment costs between the two jurisdictions. The Commission decided that the change to exclusive use of the DEM allocation factor should be phased in over a five-year period from 1988 to 1992. Each year during the transition period, the allocation factor for assigning costs to the interstate jurisdiction was calculated by assigning decreasing weight to the 1987 allocator (called the "composite" allocator) and increasing weight to the DEM allocator, and then summing the two weighted amounts. The transition was complete at the end of 1992, and the DEM allocator alone is now used to allocate local switching equipment costs between jurisdictions. 15. The Commission's price cap rules required LECs to include as an exogenous cost change the dollar effect attributable to the change in the interstate allocation formula each year. In this case, this means that LECs were required to treat as an exogenous cost change the dollar effect of using the allocation formulas in effect for the current tariff period (e.g., 1993-94) as compared to the prior period (e.g., 1992-93), "measured at the base period level of operations." Because the LECs are to use "base period level of operations" when measuring the cost change attributable to the change in the interstate allocation formula, the LECs are required to calculate the DEM factor for purposes of the 1992-93 and 1993-94 interstate allocation formulas based upon 1992 minutes of use. 16. To determine the exogenous cost change attributable to the change in the interstate allocation formulas for purposes of the 1993-94 annual access tariff year, US West calculated its interstate allocation formula for the current tariff year (i.e., 1993-94) using projected minutes of use, while using 1992 minutes of use to calculate its interstate allocation formula for the prior tariff year (i.e., 1992-93). In contrast, all the other price cap LECs used 1992 minutes of use in calculating their interstate allocation formulas for both the prior and the current tariff periods. 17. In the 1993 Annual Access Order, the Bureau determined that US West's method of calculating its exogenous adjustment due to the DEM transition differed from the practice of other LECs. The Bureau also found that this difference had a significant effect on US West's proposed access rates and apparently violated the Commission's rules. The Bureau therefore suspended US West's rates for one day and designated the issue of its DEM calculations as part of this investigation. 2. Positions of the Parties 18. US West asserts that, even if its DEM methodology differs from that of other LECs, it has fully complied with all Commission rules governing the exogenous treatment of DEM. US West maintains that its DEM methodology has produced a rate reduction of $5.6 million more than would have been expected if exogenous treatment had not been ordered for the transitional change amounts. 19. US West further asserts that the Commission's rules do not define the allocator for the transition years, beyond requiring that carriers should complete the transition to DEM by January 1, 1993. US West argues that DEM is not a constant number, but changes continually as the relative number of interstate and intrastate minutes changes. Thus, US West contends, every LEC is moving toward a different allocation factor. 20. In response, AT&T and MCI assert that nothing in US West's direct case refutes the Bureau's determination in the 1993 Annual Access Order that US West's method of calculating its exogenous amount was different from that used by other LECs and that its method did not appear to comply with the Commission's rules. AT&T asserts that "US West used 1992/93 measured DEM to calculate the 1992/93 DEM allocator and then shifted position and relied on 1993/94 data to calculate the 1993/94 DEM allocator." This miscalculation, AT&T asserts, resulted in the understatement of the exogenous decrease to be reported by US West for the DEM transition. AT&T and MCI assert that US West has understated its reduction in exogenous costs associated with the DEM transition by approximately $5.5 million. 3. Discussion 21. The Commission's rules require a LEC to recognize exogenous cost changes attributable to the transition to using the DEM factor alone as the method of allocating local switching equipment costs between interstate and intrastate jurisdictions. As discussed above, during each transition year, the interstate allocation factor was computed as the weighted average of two elements. The first element was the percentage of switching costs allocated to the interstate jurisdiction as of December 31, 1987, weighted by a factor that decreased each year of the transition. The second element was the interstate DEM allocator, weighted by a factor that increased each year of the transition. Beginning with tariff year 1993-94, the transition to total reliance on DEM to allocate costs was complete. 22. As discussed above, the DEM allocator is the ratio of interstate minutes of holding time of the originating and terminating local switching equipment to total minutes of such holding time. The exogenous separations event is the change in the interstate allocation formula. The exogenous event is not, as US West suggests, the change in the DEM factor attributable to a change in the relative number of interstate and intrastate minutes of holding time. If there were no transition, there would be no exogenous event simply because US West's DEM factor changed. To capture the dollar effect of the change in the allocations method, it is necessary to isolate the change in costs allocated to the interstate jurisdiction attributable to our modification of the allocation formula, from the change in such costs attributable to a change in the ratio of interstate to intrastate holding time for US West. 23. Our rules required US West to hold the DEM factor constant at the base year level. Thus, the LEC should have used the 1992 minutes of use as reported in its ARMIS 43-04, March 1993 report to compute its interstate allocation factors for both the 1992-93 base tariff period and the tariff period under investigation. US West's methodology incorrectly treated the change in the DEM allocator itself as exogenous by using forecasted minutes of use to derive a 1993 allocation factor for purposes of its 1993-94 annual access tariff filing. This led to an understatement of the cost changes attributable to the change in the different separations formulas applied in the 1992-93 and 1993-94 tariff years. We therefore direct US West to recalculate its exogenous cost change by substituting 1992 minutes of use for the forecasted minutes of use, and to revise its price cap indices, upper limits on the service band indices in the service categories and subcategories, and maximum carrier common line rates, and to implement refunds in accordance with the directions in Section V of this Order. C. Calculation of the "g" Factor by Bell Atlantic and SNET 1. Background 24. The LECs' common lines are loops linking the end user's premises to the LEC's central office. The actual costs of these loops are non-traffic sensitive; that is, the cost of a loop does not depend on how much it is used. Although common line costs are non-traffic sensitive, these costs are nonetheless recovered in part through per minute charges. Specifically, the LECs recover a portion of common line costs through carrier common line charges assessed on interexchange carriers and other access customers using switched, interstate access services based on minutes of use. The LECs recover the remainder of common line costs through flat rates charged to end users. The rules governing how a LEC must compute interstate rates to recover common line costs appear in Part 69 of our rules. Price cap regulation treats these elements collectively in the common line basket. 25. The price cap formula for the common line basket is slightly different from the formula used to cap the other baskets. This difference stems from the fact that, although actual common line costs are non-traffic sensitive, a portion of those costs is recovered through the per minute carrier common line charge. In fashioning the price cap plan, the Commission sought to devise a formula for the carrier common line rates that would pass a portion of the benefits of the growth in minutes per line for the common line element to the interstate ratepayers, while allowing a LEC to continue to recover a reasonable level of common line costs and providing incentives for increased LEC productivity. The carrier common line formula therefore includes a surrogate growth factor based on the LECs' historical common line demand growth (i.e., growth in minutes per line) to protect ratepayers from paying common line charges that are unreasonably high in light of demand growth. Changes in common line demand growth are measured by a factor known as the "g" factor. The price cap rules define the "g" factor as "the ratio of minutes of use per access line during the base period, to minutes of use per access line during the previous base period, minus 1." The Commission's rules define the "base period" for price cap LECs as "the 12-month period ending six months prior to the effective date of annual price cap tariffs . . . ." The higher the "g" factor, the lower the common line PCI will be. 26. In their "g" factor calculations for the 1993 annual access filings, Bell Atlantic annualized its fourth quarter 1992 line count and SNET annualized its December 1992 line count instead of using the actual line count for the full calendar year 1992 base period. The "g" factor calculations of Bell Atlantic and SNET were therefore designated for investigation. 27. In its "g" factor calculations for the 1994, 1995, and 1996 annual access filings, Bell Atlantic again annualized its prior year fourth quarter (1993, 1994, and 1995, respectively) line count. The Bureau suspended Bell Atlantic's calculation of the "g" factor for purposes of its 1994, 1995, and 1996 filings for one day and incorporated them into the 1993 investigation. The Bureau also ordered that Bell Atlantic's 1994, 1995, and 1996 transmittals be subject to the 1993 accounting order. 2. Positions of the Parties 28. Bell Atlantic asserts that it correctly calculated the "g" factor in its annual price cap tariff filings. Bell Atlantic states that it has consistently used the end-of-year number of access lines. Bell Atlantic and SNET argue that the basis for determining minutes and lines must be consistent from year to year to avoid distortions in the PCI. Bell Atlantic contends that since all of the individual factors underlying the "g" calculations represent annualized amounts, there is no distortion in the calculation. Applied consistently over time, Bell Atlantic argues, its method leads to reasonable rates. SNET asserts that there is no material difference in its "g" factor whether using a December comparison, or a comparison based on annual figures. This conclusion notwithstanding, SNET expresses a willingness to use the full year methodology if the Commission so requires. 29. AT&T responds that the Commission should not permit SNET and Bell Atlantic to perpetuate an erroneous practice merely for the sake of preserving historical consistency for those carriers. AT&T argues that the carriers' reliance on a partial year's line count data to develop their "g" factors has resulted in substantial overstatements of their common line basket PCIs. According to AT&T, Bell Atlantic's PCI was overstated by $5.45 million, while SNET's price cap for that basket was overstated by $104,000. AT&T argues that relying on partial year data could impede administration and enforcement of the LEC price cap plan because it is impossible to validate the accuracy of Bell Atlantic's and SNET's "g" factor computations from the full annual line count data reported in tariff review plans (TRPs) for these tariff filings. 3. Discussion 30. We find that SNET (in its 1993 annual access filing) and Bell Atlantic (in its 1993, 1994, 1995, and 1996 annual access filings) incorrectly calculated the "g" factor. Section 61.45(c) of the rules, as previously stated, defines "g" as "the ratio of minutes of use per access line during the base period, to minutes of use per access line during the previous base period, minus 1." Revenues included in the PCI calculation are based on an entire year period. The various factors in the PCI formula should therefore be defined using similar periods to avoid distortions based on seasonal variations. Thus, a count of access lines in the appropriate year should reflect the average line count "during the base period" year instead of the line count during some portion of the year. Use of partial year data creates the risk that seasonal fluctuations in demand occurring during the year will skew the PCI calculations. Full year data are required to avoid this risk. We note that a full year's average should be used in both the base year and the prior base year to avoid the inaccuracy that would occur if data from different periods were used to calculate average line counts in the two years. We therefore direct Bell Atlantic and SNET to correct their "g" calculations, and to revise their price cap indices, upper limits on the service band indices in the service categories and subcategories, and maximum carrier common line rates, and to implement refunds in accordance with the directions in Section V of this Order. D. Bell Atlantic's and Pacific Bell's Omission of End User Revenues from the Common Line Basket for Sharing Purposes 1. Background 31. Under the rules in effect at the time of the 1993 and 1994 annual access filings, price cap LECs electing the 3.3 percent productivity factor were permitted to retain all of their earnings up to 12.25 percent, but were required to share 50 percent of their earnings between 12.25 percent and 16.25 percent, and 100 percent of their earnings in excess of 16.25 percent. LECs selecting the 4.3 percent productivity factor were permitted to retain all of their earnings up to 13.25 percent, but were required to share with their customers 50 percent of their earnings between 13.25 percent and 17.25 percent, and 100 percent of their earnings in excess of 17.25 percent. Under the LEC price cap sharing mechanism, the customer's share plus interest is effectuated through a one-time reduction in the PCI for the next rate period, calculated in the same manner as other exogenous changes in the formula. On the other hand, the low-end adjustment mechanism entitled carriers whose earnings dropped below 10.25 percent to retarget rates to that level in the following tariff year. Together, these adjustments were safeguards against possible errors the Commission may have made in setting the productivity factor. Section 61.45(d)(4) of the Commission's rules requires carriers to allocate exogenous cost changes, such as sharing adjustments, among price cap baskets on a "cost-causative" basis. 32. In its 1993 annual access tariff filing, Bell Atlantic subtracted end user revenues (also known as subscriber line revenues) from total common line basket revenues for purposes of allocating sharing amounts among the four price cap baskets. In the 1993 Annual Access Order, the Bureau designated the issue of whether this action by Bell Atlantic was correct. In its direct case filed in response to the 1993 Annual Access Order, Pacific stated that Pacific Bell (but not Nevada Bell) also omitted end user revenues from the common line basket for purposes of allocating sharing amounts among price cap baskets. 33. In their 1994, 1995, and 1996 annual access tariff filings, Bell Atlantic and Pacific Bell again subtracted end user revenues from total common line basket revenues for purposes of allocating sharing amounts among the four price cap baskets. In the 1994 Annual Access Orders, the Price Cap Carriers' 1995 Annual Access Order, and the 1996 Annual Access Order, the Bureau found that the exclusion of subscriber line revenues from the computation that allocates the sharing obligation among different baskets was one of the issues designated for investigation in CC Docket No. 93-193, suspended Bell Atlantic's and Pacific Bell's 1994, 1995, and 1996 tariffs for one day, and incorporated them into the tariff investigation in CC Docket No. 93-193. The Bureau also ordered that Bell Atlantic's and Pacific Bell's 1994, 1995, and 1996 transmittals be subject to the accounting order in CC Docket 93-193. 2. Positions of the Parties 34. In its direct case, Bell Atlantic argues that sharing was incorporated in the price cap rules for two purposes: (1) to function as a safety mechanism, if the Commission's productivity factor was set incorrectly; and (2) to share with customers the benefits of interstate earnings above designated levels. Bell Atlantic asserts that end user rates are based on forecasted costs and demand and, unlike other rates, "are not affected by the Price Cap indices, including the productivity factor." Bell Atlantic maintains that, because sharing amounts are based on productivity gains, "allocating sharing amounts on revenues that are not affected by productivity is not a cost-causative approach." 35. Pacific states that the Commission's price cap rules and its decisions do not specify in detail how sharing is to be allocated because the sole criterion is that sharing must be allocated on a cost-causative basis. Pacific maintains that to allocate sharing based on all interstate revenues, including end user subscriber line revenues, would assign 63 percent of the total sharing amount to common line, which, excluding the end user revenues, generates only 16 percent of the total interstate revenues. This result, according to Pacific, violates the Commission's rules that amounts be allocated on a cost-causative basis. 36. AT&T and Allnet argue that the Bureau's 1992 Annual Access Order rejected a similar attempt by Bell Atlantic and others to target their sharing allocations to particular access services that the LECs claimed had contributed most to productivity gains. AT&T asserts that the Commission should conclude that Bell Atlantic's and Pacific's PCIs based upon the exclusion of end user revenues from their sharing allocation are unreasonable, and require carriers to recompute those indices following correct assessment of cost causation. 3. Discussion 37. Bell Atlantic and Pacific Bell maintain that end-user revenues should be removed from the common line basket before a carrier calculates the basket revenue allocators (each basket's revenue as a percent of the total revenue) used to allocate sharing among the baskets. Bell Atlantic and Pacific argue that end-user charges are designed to earn the LEC a net return of 11.25 percent, the prescribed rate, and thus a sharing obligation is irrelevant because sharing is based on earnings in excess of 12.25 percent. Their basket-by-basket approach to sharing has been rejected by the Commission in the LEC Price Cap Order and LEC Price Cap Reconsideration Order. The sharing mechanism was created as a backstop to the price cap plan as a whole and is based on overall interstate earnings rather than individual rates or basket earnings. This unitary approach to sharing is consistent with the unitary productivity X-factor, that is based on the overall performance of the interstate access market. 38. Section 61.45(d)(4) of the Commission's rules provides that exogenous cost changes, such as sharing adjustments, shall be allocated among the price cap baskets on a cost-causative basis. Basket revenues in appropriate circumstances can be used as a proxy for costs. To exclude EUCL revenues from the common line basket distorts the use of revenues as a proxy for costs because total revenues would not used. Therefore, we reject Pacific and Bell Atlantic's contention that EUCL revenues may be excluded for purposes of allocating sharing amounts. 39. For these reasons, we conclude that Bell Atlantic in its 1993, 1994, 1995, and 1996 annual access tariff filings, and Pacific, in its 1994, 1995, and 1996 annual access tariff filings, by excluding end user revenues from their calculations, have incorrectly allocated their sharing obligations among the various service baskets. We therefore direct Bell Atlantic and Pacific Bell to correct how they allocate their sharing adjustments among baskets, and to revise their price cap indices, upper limits on the service band indices in the service categories and subcategories, and maximum carrier common line rates, and to implement refunds in accordance with the directions in Section V of this Order. 40. Although the issue was not designated for investigation, we also find unlawful Pacific's method of allocating its sharing obligations in its 1993 annual access filing, in the facts of this particular case, because it is the same method used by Pacific Bell in its 1994, 1995, and 1996 annual access filings, and by Bell Atlantic in its 1993, 1994, 1995, and 1996 annual access filings. We do not direct Pacific to make a refund for incorrectly allocating its sharing obligations in its 1993 annual access tariff filing because under Section 204(a)(1), the rates must be suspended before refunds can be ordered and the Commission did not suspend Pacific's rates with respect to this issue in its 1993 annual filing for its sharing adjustments. 41. In the Second 1994 Annual Access Order, the Bureau stated that, after the termination of the 1993 investigation and prior to the termination of the 1994 investigation, we would permit Pacific to present any legal argument or factual circumstances that might lead us to conclude that the decisions reached in CC Docket No. 93-193 on sharing allocation issues should not control our treatment of Pacific Bell's 1994 access transmittals. As noted above, the issue raised by Pacific's 1994 annual access tariff filing (i.e., whether our price cap rules permit the exclusion of subscriber line revenues from the computation of revenues used to allocate the sharing obligation among baskets) is the same issue raised by Bell Atlantic's 1993 (and 1994, 1995, and 1996) annual access tariff filings and designated for investigation in CC Docket No. 93-193. Pacific filed comments and replies in CC Docket No. 93-193 addressing this issue in response to the 1993 Annual Access Order. 42. We find that Pacific has had sufficient opportunity to present evidence and argument on this issue and, in fact, has done so. As discussed above, Pacific has failed to persuade us that the LECs should be permitted to exclude end user revenues from the common line basket for the allocation of sharing adjustments. For these reasons, and because the issue presented is precisely the same for each year, we believe it is unnecessary to provide Pacific further opportunity to comment, and we resolve our investigation of this issue for purposes of Pacific Bell's 1994, 1995, and 1996 annual access filings. E. General Support Facility Costs 1. Background 43. On May 19, 1993, the Commission released an order adopting rules correcting the misallocation of GSF investment and related expenses among the access categories in Part 69. GSF investment includes items such as land, buildings, computers, motor vehicles, and furniture that support the operations of the carrier. Prior to the GSF Order, the Commission required LECs to exclude GSF investment from the common line category, which increased the GSF allocation to the other Part 69 categories. The GSF Order modified the Commission's rules to require that GSF investment also be allocated to the common line category. The Commission held that the exclusion of the common line category from the formula for allocating GSF investment resulted in an under- allocation of GSF investment to the common line category and an over-allocation of such investment to other access categories. The Commission also concluded that price cap LECs should be allowed to treat as exogenous the reallocation of GSF costs and that these LECs should adjust their PCIs to reflect the reallocation. The GSF Order directed the LECs to file tariff revisions reflecting the effect of the changed allocation process on fourteen days' notice, to become effective July 1, 1993, the same date their 1993 annual access tariff filings were to go into effect. The LECs filed their transmittals reflecting the tariff revisions on June 17, 1993. During its review of the LECs' annual access tariff filings, the Bureau considered the GSF tariff filings. The Bureau noted that petitions to suspend or reject the GSF filings were due at virtually the same time that the Bureau was to release the 1993 Annual Access Order. Because it had only limited time to review the GSF filings, the Bureau concluded that it should initiate an investigation to permit a more thorough review to determine whether these filings comply with the Commission's GSF Order. The Bureau therefore suspended tariffs filed pursuant to the GSF Order for one day and imposed an accounting order. 2. Positions of the Parties 44. The LECs that refiled their 1993 access rates based on the GSF reallocation assert that they reallocated their GSF costs properly and that the resulting rates are just and reasonable. Sugar Land Telephone Company (Sugar Land), a LEC that participates in NECA's common line pool but files its own traffic sensitive tariff pursuant to Section 61.39, states that its GSF costs were properly reallocated and that the revised rates were developed for the biennial period from July 1, 1993 to June 30, 1995 as required by the GSF Order. Moreover, Sugar Land states that the impact of the reallocated GSF costs resulted in a decrease in its traffic sensitive switched and special access rates consistent with the GSF Order. Bay Springs et al., also assert that their rates were properly adjusted by applying the GSF costs reallocations to their actual historical costs pursuant to the GSF Order. 45. AT&T asserts that the 26 companies that participate in the NECA common line pool, but file their own traffic sensitive rates based on historical costs pursuant to Section 61.39, received the benefits of the increase in the NECA common line charge due to the requirements of the GSF Order, but did not simultaneously reduce their traffic sensitive rates as also required by the GSF Order. AT&T maintains that these 26 companies are receiving an unwarranted double recovery of approximately $3.4 million because of this failure. AT&T argues that although NECA may have no authority to compel these 26 companies to file tariffs that reflect the appropriate traffic sensitive reductions, NECA must still make reasonable efforts to ensure that all LECs in the NECA pool comply with the Commission's rules. Finally, AT&T argues that if LEC data submitted to NECA do not comply with the Commission's rules, NECA must correct the data in its revenue requirement computations. AT&T claims that NECA is obligated by Commission order to adjust the common line revenue requirement to eliminate the $3.4 million double recovery. 46. NECA contends that AT&T would have the Commission contradict its own rules regarding the allocation of GSF related costs to the common line category. Further, although NECA states that it does not dispute AT&T's claim that it has the responsibility to ensure that the Commission's rules are followed as they relate to the revenue requirement and revenue distribution processes of its tariff participants, NECA claims that its filing does reflect the accurate common line revenue requirement data. NECA argues, however, that it does not have the authority to withhold common line payments to LECs that have provided accurate common line revenue requirements in accordance with Commission rules. 47. Among the LECs identified by AT&T that allegedly double recovered GSF costs, Coastal et al. (Coastal), the LECs represented by GVNW, Inc./Management (GVNW), and the City of Brookings Municipal Telephone filed rebuttals. Coastal and GVNW argue that the small LECs that participate in NECA's common line pool but file their own traffic sensitive tariffs, were not required to retroactively apply the changes in the GSF reallocation which became effective on July 1, 1993, subsequent to the historic period ending December 31, 1992, upon which their 1993 traffic sensitive rates were based. GVNW asserts that the GSF changes would be reflected in the 1995 tariff filing based upon 1993 historical data. The City of Brookings Municipal Telephone which participates in NECA's common line pool but elected to file its own traffic sensitive tariff for the first time in 1993, asserts that it correctly based its traffic sensitive rates on NECA's average schedule pool settlement method pursuant to Section 61.39 (b)(2). 3. Discussion 48. We have reviewed each carrier's GSF tariff transmittal and all associated pleadings and conclude that most carriers' costs and rates properly reflect the GSF allocation in the 1993 annual filings. We conclude that there may have been a double recovery of a portion of GSF costs by carriers that participated in NECA's common line tariff but filed individual tariffs for the traffic sensitive rates, pursuant to Section 61.39 of the Commission's rules. These overcharges would have occurred from July 1, 1993 through June 30, 1995; for these carriers the GSF reallocation may have been first reflected in traffic sensitive rates effective on July 1, 1995. These carriers fully recovered their GSF expense through their traffic sensitive rates, because their traffic sensitive rates were based on 1992 costs before the GSF reallocation on June 17, 1993. At the same time, NECA's rates which became effective on July 1, 1993 reflected the reallocation of GSF cost to the common line category, pursuant to Section 61.38 of the Commission's Rules. Therefore, there was a double recovery for these Section 61.39 companies that recovered their full GSF expense through their traffic sensitive rates and again through the NECA common line pool, unless they adjusted their individual traffic sensitive rates. 49. Coastal and GVNW are correct that the GSF reallocation occurred after the 1992 calendar year upon which the traffic sensitive rates were based. The rates in question, however, were unreasonable to the extent carriers were recovering the same cost through both the carrier common line (CCL) rates and traffic sensitive rates and should have eliminated this double recovery in light of the Commission's determination in the GSF Order that it was necessary to correct for the misallocation of GSF costs because the exclusion of the common line category from the formula for allocating GSF investment allocated too little GSF investment to the common line category and too much GSF investment to other access categories. 50. The record is not clear that each of these LECs did not correct their individually filed traffic sensitive rates. We direct the carriers that participated in NECA's common line pool and filed individual tariffs for traffic sensitive rates pursuant to Section 61.39 to provide a complete explanation of any rate adjustments they made to prevent the double recovery described above. This shall include explanations detailing the allocation of GSF costs and revisions to traffic sensitive rates and tariffs previously filed to eliminate any double recovery. We further direct these LECs to submit a plan for any corrective action that may be necessary to eliminate the double recovery of GSF costs. Carriers may be required to make refunds, depending on the facts submitted. We require this information to be submitted by May 1, 1997. We will delegate to the Chief, Common Carrier Bureau authority to review the LECs' explanations of GSF allocations, rate adjustments, and any plans for corrective action that may be necessary to correct for double recovery of GSF costs, as well as to take any further actions that may be necessary to ensure compliance with our requirements. F. Category Assignment for Line Information Data Base Query Charge 1. Background 51. When setting up calls, interexchange carriers pay LECs for access to the Line Information Data Base (LIDB) to validate LEC-issued calling cards through the LEC data bases. In the 1993 annual access filings, the LECs incorporated LIDB service for the first time into the price cap baskets and placed that service in the traffic sensitive basket. With the exception of one LEC, they included the per query charges (LIDB query and LIDB transport) in the local transport service category within that basket. The LIDB query charge is the charge for making a data base inquiry to validate a customer's calling card number. The LIDB transport charge, for connection between the switching transfer point port and a LIDB data base, is also charged on a per query basis. United is the only carrier that placed the per query elements in the local switching category of the traffic sensitive basket. 52. On January 29, 1993, the Commission created a new, separate service category within the traffic sensitive basket for data base access services, effective March 1, 1993. As noted previously, the LECs filed their 1993 annual access tariffs on April 2, 1993. In the 1993 Annual Access Order, we concluded that we should investigate the proposed tariff changes of those price cap companies that incorporated LIDB charges into the price cap baskets. 2. Positions of the Parties 53. United and Allnet assert that transporting a LIDB query from the interexchange carrier (IXC) to the LEC switching transfer point requires the use of transport facilities, while transporting the query among the facilities of the LEC and determining where to route the underlying call requires only the use of switching facilities. United and Allnet maintain that switching facilities are used to route calls to their destination or to determine whether calls should be completed at all. According to these parties, the LIDB similarly makes logical decisions concerning call routing. Thus, they reason, LIDB should be included in the local switching category of the traffic sensitive basket. 54. Many of the LECs, however, argue that the LIDB per query charges should be assigned to the transport category in the traffic sensitive basket. Ameritech asserts that, because LIDB includes a charge for call transport, both the LIDB per query charges should be placed in the local transport service category within the traffic sensitive basket. Southwestern argues that LIDB validates billing information; it does not provide call routing and delivery information. The fact that the query is associated with a call is not enough to justify placing LIDB in the local switching category, according to Southwestern. Several LECs assert that because LIDB validation service is dependent on network interconnection, and because network interconnection costs and revenues are included in the transport category, LIDB validation service costs and revenues should also be placed in the transport category. 55. A number of LECs also argue that the LIDB rates are properly placed in the local transport category because this placement corresponds to how LIDB investment is assigned. They maintain that under Part 32 of the Commission's rules, LIDB investment is recorded in Account 2212 - Digital Electronic Switching. These LECs state that the investment is then categorized as central office equipment (COE) Category 2 - Tandem Switching in Part 36 of the rules. Under Part 69, Tandem Switching Investment is assigned to the local transport category. Therefore, in order to maintain consistency between the assignment of investment and revenues, these carriers argue, LIDB rates are properly placed in the local transport category. 56. AT&T argues that a new service category, with five percent upper and lower band limits, should be established within the traffic sensitive basket for the LIDB per query charges because there is no competition for LIDB and, therefore, there is the danger that the LECs will raise the LIDB per query charges in order to lower the prices for other more competitive services. 57. The LECs generally oppose establishing a new service category for the LIDB query element, arguing that a new category is unnecessary and would conflict with the Commission's price cap goal of simplifying regulation. They assert that the practical effect of establishing a new service category for the LIDB query charge would be to create rate element level banding, which the Commission rejected during the price cap proceeding. 58. GTE asserts that, while it believes that the most appropriate category for the LIDB query charge is the local transport category in the traffic sensitive basket, as an alternative, the charge could be included in the 800 data base category, the category established by the 800 Data Base Access Order. This alternative, GTE argues, should resolve AT&T's concern that the LECs might increase the rate for this element in order to reduce other rate elements in the local transport basket. 3. Discussion 59. As discussed above, the Commission in the 800 Data Base Order created a separate service category within the traffic sensitive basket for data base service. Interexchange carriers pay LECs' LIDB rates to verify LEC-issued calling cards through the LECs' data bases. Thus, LIDB service is actually a data base service and, therefore, is most appropriately placed in the data base service category within the traffic sensitive basket. 60. Including the LIDB charges in the data base service category, along with services such as 800 data base services, is consistent with the price cap principle that calls for grouping similar services together to limit the LECs' ability to shift costs among services in a potentially anti- competitive manner. Specifically, grouping services with common characteristics, such as similar functionalities and levels of competition, within the same category is intended to give the LECs pricing flexibility with respect to comparable services and to restrict the ability of LECs to offset increases for some services with rate decreases for dissimilar services. LIDB service and 800 data base services are not only functionally similar (in that they both provide access to data base information), but they share similar competitive circumstances (i.e., neither service is subject to competitive pressures). 61. The fact that the LIDB service involves switching functions (i.e., call routing and completion functions) does not persuade us that the LIDB charge should be included in the former local switching category of the traffic sensitive basket, as United proposes. Further, because transport services face increasing competition as a result of the Commission's expanded interconnection policies, while the LECs have a virtual monopoly over the information contained in the line information data base, placing the LIDB query charges in the transport category would be inconsistent with the Commission's price cap principle of grouping services with similar demand elasticities. 62. We conclude that the data base service category within the traffic sensitive basket is the appropriate category in which to place the LIDB query charges. We therefore direct the LECs referenced in Appendix B to place the LIDB query charges in the data base service category within the traffic sensitive basket and to revise their price cap indices, upper limits on the service band indices in the service categories and subcategories, and maximum carrier common line rates, and to implement refunds for the 1993 annual access tariff in accordance with the directions in Section V of this Order. 63. Although the issue of the proper service category placement for LIDB query charges was not designated for investigation in the 1994, 1995, and 1996 annual access filings, we also find the LECs' placement of the LIDB query charges in service categories other than data base service category in these years to be unlawful for the reasons discussed, supra. We do not direct the LECs, referenced in Appendix B, to make a refund for placing the LIDB query charges in the incorrect service category for the 1994, 1995, and 1996 annual access filings because under Section 204(a)(1), the rates must be suspended before refunds can be ordered and the Commission did not suspend the 1994 through 1996 annual access rates of these LECs with respect to their placement of LIDB query charges in service categories other than the data base service category. G. Roseville Cash Working Capital 1. Background 64. Cash working capital is an estimate of the average amount of investor-supplied capital needed to fund a carrier's day-to-day operations. This amount is one element of the investment component of a rate-of-return carrier's revenue requirement used to compute rates. In order to determine the working capital requirements for day-to-day operations, lead-lag studies measure the patterns of cash inflows and outflows relative to the time when service associated with those costs and revenues is rendered. "Lead" describes those revenues and expense items that are received or paid before a service is rendered. "Lag" describes those revenue and expense items that are received or paid after service is rendered. The Commission's rules permit carriers to compute their cash working capital by using either a full lead-lag study, the "Simplified Formula Method," or the "Standard Allowance Method." Because the computation by Roseville, a rate-of-return carrier, of its cash working capital was inconsistent with those of other LECs, the Common Carrier Bureau suspended its filing for one day, issued an accounting order and included it in this investigation. 2. Positions of the Parties 65. Roseville admits that, in amending Part 65, the Commission concluded that "properly developed lead-lag studies are the most appropriate method for determining interstate cash working capital." Nonetheless, Roseville contends that nothing in those orders precluded a carrier from using a lead-lag study based on individual company circumstances. 66. Roseville contends that its cash working capital allowance was based on a properly performed lead-lag study. According to Roseville, evaluating the reasonableness of its cash working capital allowance by comparing it with those of carriers using the Standard Allowance Method is improper because Roseville's result is more accurate. Therefore, Roseville maintains, its calculation of its cash working capital allowance results in just and reasonable rates. No oppositions or rebuttal were filed addressing this issue. 3. Discussion 67. We have reviewed Roseville's lead-lag study and have determined that this study contains several flaws. First, the lead-lag study is outdated because it used 1989 data and there is no way for us to determine if these data are representative of Roseville's 1993 operations covered by the tariff under review. 68. Second, the months studied for individual revenue categories were not consistent. For example, Roseville used September-December 1989 to calculate the Carrier Access Billing revenue lag, but used April-June 1989 to calculate the Other Common Carrier Revenue lag. 69. Third, Roseville included in its lead-lag study adjustments to prior period data that, although permitted under NECA's internal procedures, lead to unreasonable results when computing cash working capital requirements. NECA's procedures allow for adjustments to prior period data for up to 24 months after rates based on the data became effective. NECA's retroactive adjustment mechanism allows carriers to adjust their previously submitted data to account for such events as erroneous separations studies, clerical errors, rule changes, and extraordinary accounting adjustments. For its lead-lag study, Roseville chose a 12-month period that included a substantial retroactive adjustment (i.e., an adjustment that resulted in Roseville's receiving a large late payment from the NECA settlement process) that significantly increased Roseville's revenue lag. Because there is little, if any, correlation between retroactive adjustments and current expenses, we conclude that the former are not a reasonable indicator of the cash working capital needed by Roseville to finance its day-to-day operations. We note also that LECs have not previously included these types of retroactive adjustments from NECA in their lead-lag studies and we believe that the inclusion of such adjustments by Roseville distorted its lead-lag results. 70. Finally, Roseville's computation of its income tax lag is flawed because it includes delays in the receipt of tax refunds for overpayment of estimated taxes. We find it is inappropriate to permit Roseville to include tax overpayments as part of its lead lag study used to support its 1993 cash working capital allowance. Ratepayers should not bear the cost of management's decision to overpay the company's estimated taxes. The overpayment of taxes is not a day-to-day cost of doing business and thus, it does not warrant inclusion in a carrier's working capital allowance. Collectively, these observations lead us to conclude that Roseville's lead-lag study cannot be used to compute its cash working capital allowance because the study produces an inaccurate estimate of its revenue requirement. We therefore require Roseville to utilize the standard 15-day allowance method to calculate its cash working capital, and to implement refunds in accordance with the directions in Section V.D. of this Order. To determine the carrier's working capital allowance under the standard 15-day allowance method, the carrier's total annual cash operating expenses are divided by 365 days to determine the average daily cash operating expenses. A carrier's average daily cash operating expenses are then multiplied by the standard cash working capital allowance of 15 days to derive its cash working capital determination. III. AT&T'S APPLICATION FOR REVIEW 1. Background 71. In a companion order to the Modification of Final Judgment (MFJ), the U.S. District Court required AT&T to guarantee the Bell Operating Companies' (BOCs') recovery of the costs of providing equal access to IXCs. The District Court also directed AT&T and the BOCs to develop a procedure to account for equal access and network reconfiguration (EANR) costs. In 1985, AT&T and the BOCs petitioned the Commission to approve an accounting plan for EANR costs. AT&T and the BOCs estimated that total equal access expenditures would exceed $2.6 billion and would be incurred over a short time. 72. In response, the Commission in the EANR Order identified only certain costs that would be treated as equal access costs, including: (1) initial additional costs for hardware and software related directly to the provision of equal access, and not otherwise required; (2) costs of connecting offices that serve competitive IXCs; and (3) costs that have been incurred as a result of bona fiderequests for conversion to equal access. The Commission required the BOCs to amortize equal access costs over an eight-year period that would expire on December 31, 1993. The Commission concluded that the establishment of a fixed amortization period with a definite termination point of December 31, 1993, would avoid substantial irregular fluctuations in rates and reduce the administrative burdens of tracking equal access costs. 73. In the LEC Price Cap Order, the Commission decided to treat all equal access costs endogenously because the mandatory price cap LECs had converted most of their end offices to equal access and most of these equal access costs were embedded in their initial price cap rates. The Commission thus found that it was unnecessary to further promote equal access conversion among price cap carriers by treating those costs as exogenous. The Commission also noted the potential difficulties associated with assessing future equal access exogenous cost claims by LECs, and the corresponding risk that carriers "could willfully or inadvertently shift switched access costs into the equal access category. . . ." 74. In the LEC Price Cap Reconsideration Order, the Commission affirmed its decision to treat equal access costs endogenously. In addition, the Commission rejected a proposal that would have required a downward exogenous cost adjustment to the BOCs' PCIs upon the termination of the equal access cost amortization. In reaching its decision, the Commission found that endogenous cost treatment for the elimination of equal access costs is consistent with its treatment for changes in depreciation levels. The Commission determined that nothing in the "meager factual record" persuaded the Commission "to depart from our practice of not adjusting PCI levels to reflect levels of cost recovery" so as to require a downward exogenous cost adjustment in 1994 to eliminate all equal access costs. 75. In the 1994 Annual Access Orders, the Bureau denied AT&T's and MCI's petition to suspend and investigate the 1994 annual LEC access tariff filings on the grounds that the price cap carriers had failed to make adjustments to their price cap indices to reflect the full amortization of equal access costs. The Bureau stated that, in the LEC Price Cap Reconsideration Order, the Commission had rejected a proposal that would "require a downward adjustment in PCI levels in 1994 to eliminate all equal access costs." The Bureau found that, even if the equal access cost amortization did warrant exogenous treatment, such treatment would require a substantive rule change because Section 61.45(d) does not provide for exogenous treatment of the equal access cost amortization and no LEC has otherwise petitioned for, and been granted, a waiver of that rule. AT&T filed an application for review of that decision. MCI filed comments in support of AT&T's application for review. Bell Atlantic, BellSouth, NYNEX, Pacific, Southwestern, and US West filed oppositions. 2. Positions of the Parties 76. AT&T alleges that the Bureau erred in "deny[ing] exogenous treatment of [the expiration of] equal access cost amortizations for . . . LECs subject to price cap regulation." AT&T contends that, because equal access costs were fully amortized on December 31, 1993, the LECs should be required to treat the expiration of the equal access cost amortization as an exogenous adjustment. AT&T asserts that, contrary to the Bureau's finding in the 1994 Annual Access Orders, the Commission's decision in the LEC Price Cap Order to accord endogenous treatment to the ongoing costs of equal access conversion "did not preclude exogenous treatment of the LECs' equal access cost amortization." AT&T claims that the Commission in the LEC Price Cap Order "addressed the appropriate treatment of the LECs' ongoing costs of converting to equal access, rather than the amortization of non-capitalized equal access costs previously incurred by those carriers under rate of return regulation." AT&T contends that the Commission's decision in the LEC Price Cap Order "to treat ongoing equal access costs endogenously" was based on the difficulty of assessing equal access costs and to prevent deliberate or inadvertent cost shifting. AT&T claims that these considerations are inapplicable to the "amortization of previously incurred equal access conversion expenses because those amounts had already been reflected in the carriers' books well prior to the adoption of incentive regulation, thereby obviating the likelihood of deliberate or unintentional misallocation of switched access costs." 77. AT&T contends that the LEC Price Cap Reconsideration Order similarly does not preclude exogenous treatment of the termination of equal access cost amortization. AT&T asserts that the LEC Price Cap Reconsideration Order declined to treat the expiration of the amortization as exogenous based on the "meager factual record" that was then available. AT&T argues that "[n]o such concerns are present . . . because all of the BOCs have made filings with the Decree Court affirming that they have fully recovered their equal access and network reconfiguration expenses." AT&T also states that none of the other LECs subject to the equal access cost amortization submitted any showing in their 1994 annual access tariff filings that they have not also fully recovered those costs. AT&T argues that the Bureau incorrectly determined in the 1994 Annual Access Ordersthat allowing exogenous cost treatment of the LECs' equal access expense amortization requires a rulemaking or a successful LEC waiver request because Section 61.45(d)(1)(vi) provides exogenous cost treatment for "such . . . other extraordinary exogenous costs changes as the Commission shall permit or require . . . ." 78. MCI urges the Commission to grant AT&T's application for review. MCI maintains that the BOCs "will experience [a] . . . cost change in 1994 that stems from factors beyond their control" because "there is a reduction in the LECs' costs which results from the completion of a Commission-mandated amortization, and not from productivity-enhancing efforts undertaken by the LECs." 79. Bell Atlantic, BellSouth, Pacific, Southwestern, NYNEX, and US West contend that the Commission has repeatedly rejected arguments that the ongoing costs of converting to equal access, as well as the completion of the amortization of such costs, should be accorded exogenous cost treatment. They assert that the Commission has consistently held that all equal access costs are to be treated endogenously. Bell Atlantic and NYNEX claim that there has been no relevant change in the law or the facts since the Commission first decided this issue that would warrant a change in the treatment of these costs. Bell Atlantic, BellSouth, NYNEX, and Pacific argue that the Bureau would violate the Commission's rules if it were to provide for exogenous treatment for the expiration of equal access costs. NYNEX asserts that a change in the classification of equal access costs would require a rulemaking proceeding or a grant of a LEC petition to waive the rule. NYNEX argues that the "meager factual record" noted by the Commission in the LEC Price Cap Reconsideration Order concerned the issue of control over equal access costs. NYNEX asserts that AT&T has failed to present any new facts that were not before the Commission in the original price cap orders to warrant a change in the treatment of equal access costs. 80. Southwestern asserts that AT&T's claim that the BOCs have made filings with the Decree Court affirming that they have all fully recovered their equal access and network reconfiguration expenses is incorrect. For example, Southwestern states that it is currently making equal access conversion by means of alternate technology to 73 Oklahoma central offices, and is upgrading 11 other Oklahoma central offices to equal access by full switch replacement. 3. Discussion 81. In the LEC Price Cap Order and in the LEC Price Cap Reconsideration Order, we determined that the amortization of equal access costs, as well as the expiration of the amortization of such costs, should be treated endogenously under the LEC price cap plan. Section 61.45(d) restricts the categories of cost changes that price cap LECs are allowed to treat exogenously to those specifically listed in that rule and those that the Commission may subsequently designate as exogenous. That section does not include equal access costs among those eligible for exogenous cost treatment. Therefore, a plain reading of Section 61.45(d) precludes exogenous treatment of equal access costs. In addition, even if the completion of the equal access cost amortization does warrant exogenous treatment, such treatment would require a substantive rule change or a waiver of Section 61.45(d) of the Commission's rules. 82. Because exogenous treatment of amortized equal access expenses would require a rulemaking, a waiver application, or an application for declaratory ruling, we deny AT&T's application for review of the 1994 Annual Access Orders. We have invited comment in the access charge reform rulemaking proceeding on whether to amend our rules to require incumbent LECs to make an exogenous decrease to one or more of their PCIs to account for the completion of the equal access expense amortization on December 31, 1993. We will address this issue in that rulemaking proceeding. IV. SOUTHWESTERN'S PETITION FOR CLARIFICATION OR RECONSIDERATION 1. Background 83. Southwestern's petition addresses two issues raised by the 1994 investigations. First, in the 1994 Annual Access Orders, the Bureau concluded that certain carriers' proposals to treat Commission regulatory fees as exogenous costs in their tariff filings violated the price cap rules. The Bureau reasoned that Section 61.45(d) limits the categories of exogenous costs to those listed in the rule and those designated as such by Commission order and that Commission regulatory fees are neither listed as exogenous in the rule nor have they been designated as such by Commission order. The Bureau stated that, absent a rulemaking, the only means available to obtain exogenous treatment for the regulatory fees is to secure a waiver of Section 61.45(d). Southwestern, although it was not one of the carriers that included Commission regulatory fees as exogenous costs in its tariff filings, requested that the Commission "clarify or reconsider that part of . . . [the First 1994 Annual Access Order] that implies that local exchange carriers (LECs) subject to price cap regulation that wish to treat the new regulatory fees as exogenous costs should petition for a waiver of the Commission's rules." 84. The second issue raised in Southwestern's petition concerns its $6.04 fixed mileage charge for DS1 services with zero miles of interoffice transport, applicable to the link between the distribution (DSX) bay and the switch. In the First 1994 Annual Access Order, the Bureau found that Southwestern's DS1 zero mileage rate element was below the applicable PCIs and within the governing service bands. The Bureau also found that Southwestern had sufficiently responded to a petition filed by MFS Communications Company concerning this charge. Nonetheless the Bureau, concerned about the potential for double recovery through the DS1 direct-trunked transport charge (DTT) for transmission between the DSX bay and the switch and again through the residual interconnection charges (RICs), suspended the tariff revisions that increased the fixed mileage charge for DS1 services with zero miles of interoffice transport and made them subject to the Commission's on-going expanded interconnection investigation in CC Docket No. 93-162 and the accounting order in that proceeding. In its current petition, Southwestern has requested that the Commission "clarify that. . . [Southwestern's] proposed $6.04 fixed mileage charge for DS1 services with zero miles of interoffice transport is not subject to the expanded interconnection investigation." 85. As previously stated, in its 1994 annual access filing, Southwestern had proposed the $6.04 DS1 zero-mileage charge in the switched transport portion of its tariff under Transmittal No. 2344. Then in response to an informal request from Commission staff, Southwestern also provided for the $6.04 charge in the expanded interconnection portion of its tariff under Transmittal No. 2364. Prior to these two transmittals, Southwestern filed Transmittal No. 2330, which clarified that the $6.04 DS1 charge for a given link would be paid by either the expanded interconnection customer using the link or the switched transport customer using the link but not by both. The Bureau's Order made both Transmittal Nos. 2344 and 2364 subject to the expanded interconnection investigation. The Bureau did not designate the matter of these transmittals for investigation in any subsequent supplemental designation orders that would have established a notice and comment filing cycle. 2. Position of the Parties 86. With respect to the treatment for ratemaking purposes of Commission regulatory fees paid by price cap LECs, Southwestern claims that LECs have not always been required to file petitions for waiver to obtain exogenous cost treatment of items not included under Section 61.45(d)(1)(vi) of the Commission's rules, and that absent a rule change, a petition for waiver should not be required. With respect to the carrier's fixed mileage charge for DS1 services with zero miles of interoffice transport, Southwestern notes that the Bureau found in the First 1994 Annual Access Order that the charge was below the applicable price cap indices and within the applicable service bands. Southwestern maintains that in light of that determination, the $6.04 charge for the DS1 zero-mileage rate element should have been allowed to take effect without further investigation. 87. BellSouth, filing comments in support of Southwestern's petition concerning exogenous costs, stated that the Bureau misinterpreted the Commission's rules when it claimed that Section 61.45(d) limited the categories of costs eligible for exogenous treatment to those listed in the rule and that carriers must file waiver requests to obtain exogenous treatment for unlisted costs. BellSouth argues that Section 61.45(d) does not present an exhaustive list of exogenous cost changes, but also includes any other cost changes that the Commission shall permit. BellSouth also argues that the Commission has in the past permitted, without a waiver request, exogenous treatment of cost changes that were neither specifically listed in Section 61.45(d) nor designated as permitted exogenous cost changes by Commission order. 88. MCI filed comments urging the Commission to reject Southwestern's petition concerning exogenous costs. MCI points to the Commission's United Depreciation Order in which the Commission ruled that, "since general depreciation rate changes are treated endogenously under price caps, United used the correct procedural device by seeking waiver of the Commission's rules when it sought exogenous treatment for plant-related expenses." MCI claims that there is no basis for distinguishing between costs previously denied exogenous treatment and costs not specifically granted exogenous treatment. MCI argues that the Bureau was correct to reject exogenous claims until a cost is declared to be exogenous in some forum other than the tariff review process. MCI claims that this requirement would confer the fullest due process on all affected parties. 89. In its reply, Southwestern argues that the tariff process does allow parties to comment on exogenous cost issues to the extent that they affect rates. Southwestern claims that the tariff process thus adequately protects the due process rights of all parties and that the waiver process is thus unnecessary for evaluating exogenous cost issues. Southwestern also challenges MCI's claim that there is no difference between costs previously denied exogenous treatment and costs not specifically granted exogenous treatment until the Commission deems otherwise through a rulemaking or a waiver. Southwestern argues that a waiver is only necessary when there is a request to deviate from an established rule. Southwestern claims that under Section 61.45(d)(1)(vi), there is no need to request a waiver to allow a price cap carrier to file for exogenous cost treatment for a cost for which the propriety of such treatment has not been specifically addressed in the past. 3. Discussion 90. In the Regulatory Fees Order, the Bureau on its own motion, granted common carriers subject to price cap regulation a waiver of the rules to permit them to treat as exogenous costs regulatory fees and changes to those fees imposed by Section 9 of the Communications Act of 1934, as amended. In light of the Bureau's decision, the issue raised by Southwestern is now moot. We thus dismiss as moot Southwestern's petition for clarification or reconsideration of this issue. 91. As for the second issue raised in Southwestern's petition, we find upon reconsideration that Southwestern's $6.04 DS1 zero-mileage charge does not warrant an investigation at this time. We note that the Bureau found that the $6.04 switched transport charge was below the applicable PCIs and within the governing service bands. The price cap rules grant pricing flexibility for rate elements within an individual basket as long as the average price of all the rate elements within that basket falls below the applicable PCI and the rate elements are within the governing service bands. Therefore, Southwestern Bell's $6.04 charge is a presumptively reasonable rate under price caps because it falls below the applicable PCIs and within the governing service bands. We note further that no party has filed an opposition to Southwestern's petition on this issue. We therefore grant Southwestern's petition for reconsideration of this issue. 92. We conclude further that Southwestern Bell's $6.04 DS1 charge is a switched access rate element which under price cap regulation is in the trunking basket because it is not a rate element that an interconnector would have to obtain in order to achieve interconnection to Southwestern's facilities. It is, however, a rate element that a switched access customer, either directly or through an interconnector, would have to obtain in order to connect a high capacity circuit to the switch. To avoid any customer confusion, and more importantly, to ensure that an interconnector is not assessed this charge to obtain interconnection, we instruct Southwestern to eliminate the $6.04 charge for the DS1 zero-mileage rate element from the expanded interconnection portion of its tariff as filed under Transmittal No. 2364 and to eliminate the language filed under Transmittal No. 2330 stating that either the switched transport customer or the expanded interconnection customer would be assessed the $6.04 rate element but not both. V. REMEDIAL ACTIONS A. Overview 93. We direct the LECs found by this Order to have violated the Commission's rules and decisions, to apply the remedial actions in this Section V. In Subsection B, we describe the method for price cap LECs to lower on a going-forward basis the price cap indices and other pricing limits to the pricing limits that would have been in place had they been set consistent with the Commission's rules and decisions. These new PCIs will become effective on June 30, 1997, and will be used to calculate annual PCI adjustments on July 1, 1997. 94. In Subsection C, we direct each LEC to lower the PCIs for one year from July 1, 1997 through an exogenous cost change, as a refund of overcharges that may have occurred during the course of this investigation. The LECs' 1997 tariff review plans (TRPs) were filed on April 2, 1997. We direct these LECs to document the development of the PCI changes in Subsections B and C in amended TRPs to be filed on May 1, 1997, in support of their annual PCI adjustments. The effects on rates from these PCI changes must be reflected in the annual access tariff filings to become effective on July 1, 1997. 95. In Subsection D, we direct Roseville, a rate-of-return carrier, to implement a refund for its overstated cash working capital allowance by using the standard 15-day allowance method discussed in Section II.G.3., supra. Roseville is directed to submit its refund plan and supporting documentation on May 1, 1997, and is required to implement refunds by lowering its tariff rates over a one-year period from July 1, 1997 through June 30, 1998. 96. These remedial actions are applicable to: 1) U.S. West's incorrect method of calculating exogenous costs associated with a change in the method of allocating local switching equipment costs between state and interstate jurisdictions in its 1993 annual access tariff; 2) Bell Atlantic and SNET's incorrect calculation of growth in minutes of use per line and, consequently, the maximum carrier common line rates in their 1993, 1994, 1995, 1996 annual access tariffs and 1993 annual access tariff, respectively; 3) Bell Atlantic's and Pacific Bell's improper exclusion of end-user revenues from the common line basket, which led to an incorrect allocation of sharing obligations among the price cap baskets in their 1993, 1994, 1995, and 1996 annual access tariffs and 1994, 1995, and 1996 annual access tariffs, respectively; 4) price cap LECs' incorrect placement of LIDB charges in service categories other than the data base service category within the traffic sensitive basket in their 1993 annual access tariffs; and 5) Roseville's use of an overstated allowance for cash working capital, which resulted in an unjustifiably high increase in the revenue requirement in its 1993 annual access tariff. We will delegate to the Chief, Common Carrier Bureau authority to review the remedial actions discussed in this Section V and to take any action necessary to ensure compliance with these remedial actions. B. PCI and Pricing Band Recalculations to Correct for Violations of the Rules 97. In this Subsection B, we provide instructions for the price cap LECs needing to correct their PCIs and other pricing limits on a going-forward basis so that those PCIs are what would have been in place had they been calculated consistent with the Commissions rules and decisions. Recalculations are to be made for the price cap index in each basket, the SBI upper limit in each service category and subcategory, and the maximum CCL rates in the common line basket, from the date the tariffs subject to this investigation took effect through the date the PCIs, SBI upper limits, and maximum CCL rate changes pursuant to this Order take effect on June 30, 1997. Our method accounts for the intertemporal nature of the LEC price cap system -- i.e., each tariff year's PCIs, SBI upper limits, and maximum CCL rates depend upon the prior year's values. Accordingly, LECs must recalculate their PCIs, SBI upper limits, and maximum CCL rates as required by the decisions in this Order, starting with the PCIs, SBI upper limits, and maximum CCL rates in effect during the 1993 tariff year. The LECs must then recalculate their PCIs, SBI upper limits, and the maximum CCL rates in effect during the 1994 tariff year as required by the decisions in this Order, using the recalculated 1993 PCIs, SBI upper limits, and maximum CCL rates. This process is to be repeated to recalculate the PCIs, SBI upper limits, and maximum CCL rates for the 1995 and 1996 tariff years. 98. The tariff year begins on July 1st and ends on June 30th; e.g., the 1993 tariff year is the period from July 1, 1993 through June 30, 1994. Even though the LECs revise the PCIs, SBI upper limits, and maximum CCL rates at the start of each tariff year, the LECs sometimes adjust those PCIs, SBI upper limits, and maximum CCL rates as the tariff year progresses. Because it would be burdensome to recalculate each and every change to PCI, SBI upper limit, and maximum CCL rate as it occurred throughout each year, we will only require recalculations at the beginning and middle of each tariff year. This procedure will reasonably approximate the changes that occurred throughout the tariff year, because the preponderance of those changes became effective at the beginning and middle of the tariff year and, thus, the benefit from recalculating at more frequent intervals is insignificant. Therefore, in addition to recalculating the PCIs, SBI upper limits, and maximum CCL rates in effect on July 1st of each year, the LECs must recalculate the PCIs, SBI upper limits, and maximum CCL rates in effect on January 1st of each year. In the 1995 tariff year, the LECs must substitute the PCIs, SBI upper limits, and maximum CCL rates in effect on August 1, 1995 for those in effect on July 1, 1995 because of the one-month deferral in the 1995 annual filings. Thus, the price cap LECs are to apply the following four steps to recalculate their PCIs, SBI upper limits, and maximum CCL rates to become effective on June 30, 1997. 99. Step 1: Recalculate the PCI for each basket as required by the decisions in this Order, for the PCIs in effect on July 1, 1993. The LECs must then recalculate the PCIs in effect on January 1, 1994, as required by the decisions in this Order, using the recalculated July 1, 1993 PCIs. This recalculation process must be repeated with respect to the PCIs for the remaining half-year periods in the 1994, 1995 and 1996 tariff years except that for tariff year 1995, the half-year periods would fall on August 1, 1995 and January 1, 1996, as explained above. Step 2: Recalculate the SBI upper limits in each service category and subcategory in effect on July 1, 1993, using the recalculated July 1, 1993 PCIs -- e.g., if a basket is composed of four service categories, each containing two subcategories, the LECs must reduce a total of twelve SBI upper limits: the limits in the four service categories and the limits in the eight service subcategories. 100. If any service subcategory SBI in effect on July 1, 1993 exceeds its recalculated upper limit then lower that subcategory SBI to its recalculated upper limit. This procedure will produce the subcategory SBI that should have been in effect. There is no change to a service subcategory SBI, if the SBI in effect is at or below the recalculated upper limit. This part of Step 2 may be omitted if there are no service subcategories within the service category. 101. For any service subcategory SBI exceeding its recalculated upper limit, adjust the service category SBI to which the subcategory belongs, since a service category SBI is a weighted average of its subcategory SBIs. If any service category SBI in effect on July 1, 1993, as adjusted, exceeds its recalculated upper limit then lower that service category SBI to its recalculated upper limit. This procedure will produce the category SBI that should have been in effect. Adjust the basket API in effect on July 1, 1993, since an API is a weighted average of its service category SBIs. In addition, the LECs are directed to recalculate the maximum CCL rate in effect on July 1, 1993, using the recalculated PCI in Step 1. 102. Step 3: Lower the subcategory SBIs on January 1, 1994 to flow through any adjustments to the previous period's SBI as calculated in Step 2. Lower the service category SBI to reflect these adjusted subcategory SBIs on January 1, 1994. If any service category SBI in effect on January 1, 1994, as adjusted, exceeds its recalculated upper limit then lower that service category SBI to its recalculated upper limit. Adjust the API to reflect these adjustments to the service category SBIs on January 1, 1994. In addition, the LECs are directed to recalculate the maximum CCL rate in effect on January 1, 1994 to flow through any adjustment to the maximum CCL rate as calculated in Step 2. 103. Step 4: Return to Step 2 to recalculate upper SBI limits for the service categories and subcategories, and the maximum CCL rate on January 1, 1994. The LECs are directed to apply the PCIs adjusted in Step 1, the maximum CCL rate and the service category and subcategory SBIs adjusted in Step 3 for January 1, 1994. The LECs must repeat this procedure for the remaining half- year intervals in the 1994, 1995, and 1996 tariff years. The PCIs, SBI upper limits, and maximum CCL rate recalculated for June 30, 1997 are the ones to be adjusted in the tariff filings making the annual adjustments to the PCIs on July 1, 1997, as adjusted for other index revisions that may occur beforehand. The amended TRPs to be filed May 1, 1997, showing the PCIs to become effective on July 1, 1997, must include documentation demonstrating that those indexes will comply with the decisions in this Order. Any rate effects from lowering the PCIs, SBI upper limits, and maximum CCL rates pursuant to this Subsection B must be reflected in each LEC's 1997 annual access tariff filing. The LECs not subject to remedial action are not required to file such documentation. C. PCI and Pricing Band Recalculations to Effectuate Refund Liability 104. In this Subsection C, we set forth the refund mechanism for price cap LECs that based on the findings of this investigation must compensate customers for overcharges incurred during the course of this investigation. The LECs, specified in paragraph 96, supra, tariff filings of which were suspended, set for investigation, and made subject to accounting orders must refund to their customers all amounts, plus interest, collected as a result of overcharges. The refunds will be implemented through a one-year exogenous cost adjustment to the PCIs incorporated in the annual access tariff filings to become effective on July 1, 1997. We conclude the LECs overcharged customers to the extent that: 1) any API, adjusted in Step 2 or 3 of Subsection B to incorporate changes to its service category SBIs, exceeds its PCI as recalculated in Step 1 of Subsection B; 2) any service category SBI, adjusted in Step 2 or 3 of Subsection B to incorporate changes to its subcategory SBIs, exceeds its SBI upper limit as recalculated in Step 2 of Subsection B; 3) any subcategory SBI in effect exceeds its upper limit as recalculated in Step 2 of Subsection B; and 4) any CCL rate in effect exceeds the maximum CCL rate as recalculated in Step 2 in Subsection B. 105. We direct the price cap LECs to apply the following six steps in order to calculate the exogenous cost change to implement refunds: 1) calculate the percent by which any API exceeds its PCI, or any SBI exceeds its SBI upper limit, or any CCL rate exceeds the maximum CCL rate in the four instances set forth in the preceding paragraph, at the beginning and middle of each tariff year from 1993 through 1996, from July 1, 1993 through June 30, 1997, except that LECs should substitute August 1, 1995 for July 1, 1995 as a result of the one month deferral in the 1995 annual filings; 2) multiply the relevant basket, or service category or subcategory revenue by the above percentages, using the base year revenue in effect for the tariff year; 3) multiply each amount calculated in Step 2 by the relevant basket, service category or subcategory ratio of revenue in 1993, the last year of this investigation, to the base year revenue to reflect the change in index value over time; 4) convert the amounts calculated in Step 3 from an annual basis to a half year basis by multiplying each amount by the ratio of number of days in the half-year interval to number of days in the tariff year; 5) add interest to each amount calculated in Step 4, using the lowest of the overpayment interest rates of the US Internal Revenue Service in effect at the midpoint of this investigation, July 1, 1995, and compound the interest at the end of each half-year refund interval until June 30, 1997; and 6) sum the amounts calculated in Step 5 by service basket. These are the exogenous cost changes to the corresponding basket's PCI. 106. These exogenous cost changes will become effective on July 1, 1997, and the LECs may remove these PCI adjustments on July 1, 1998. The amended TRPs to be filed on May 1, 1997, showing the PCIs that will become effective on July 1, 1997, must include documentation demonstrating compliance with the decisions in this Order. Any rate effects from lowering the PCIs, SBI upper limits, and maximum CCL rates pursuant to this Subsection C must be reflected in each LEC's annual access tariff filing to become effective on July 1, 1997. The LECs not subject to remedial action are not required to file such documentation. D. Roseville 107. With respect to Roseville, we conclude that the refund plus interest should reflect the amount by which Roseville's calculations for cash working capital allowance exceeded the permissible allowance in the 1993 tariff year, to be recalculated using the standard 15-day allowance method as discussed in Section II.G.3., supra. Interest shall be added to the refund amount, using the lowest of the overpayment interest rates of the US Internal Revenue Service in effect at the midpoint of this investigation, July 1, 1995, and compounded at six month intervals from January 1, 1995 through June 30, 1997. Roseville is directed to submit its refund plan and supporting documentation on May 1, 1997, and is required to implement refunds by lowering its tariff rates over a one-year period from July 1, 1997 through June 30, 1998.
