Each utility, at the time it files a tariff or application for initial rates or changes in rates shall present the proposed tariff, schedules and exhibits upon which it intends to rely in support of its application or filing. Such tariff schedules and exhibits shall include, but not necessarily be limited to, the minimum requirements outlined in Statements A to G, inclusive.

Deletion of any required schedule as outlined in this rule may cause the Commission to dismiss the tariff filing. 20.1.1.a. Provided, this rule may be waived for good cause where the proposed tariff provision has a de minimis financial impact, change in practices, a rate reduction, or removal of an obsolete rate or provision. Requests for waiver for good cause in these categories shall be accompanied by explanatory information including the reasons for die proposed change; the class or classes of customers affected; the net financial effect of the proposed change; and a verification of such information by an appropriate company official.20.1.1.b.

The public service district shall provide an additional page or pages to this Schedule showing historical nominal capital expenditures for construction, funds provided by debt, grants or other contributions in aid of construction, over die past five years. The net expenditures funded from internal cash flow should be adjusted to a real basis into the first year new rates will be in effect using a reasonable and fully explained inflation factor. The annual average of the inflation adjusted net capital expenditures will be the basis for determining revenue requirements unless adjustments are proposed and supported by any party to die case. If die public service district represents that it has additional capital requirements above the historical levels, the district shall also provide quantification and justification for additional capital expenditures above die historical, inflation adjusted average.20.1.5. Utilities that are political subdivisions of the state must maintain a minimum cash working capital reserve that is no less than one-eighth of its actual annual Operation and Maintenance Expenses. Any utility that is a political subdivision of the state and that is subject to the initial ratemaking jurisdiction of the Commission or may be subject to a Commission review of rates established by its governing bodies, shall, at the time it files its tariff application for initial rates or change in rates, or, in the case of a locally rate regulated utility, at die time it files information supporting a rate change approved by its governing bodies, clearly set out die increment, if any, included in its proposed rates that will be used to fund its statutory minimum cash working capital reserve in compliance with W. Va. Code § 24-1-l(k), and the derivation of that rate increment. The utility may propose any method of achieving and maintaining no less than die required minimum cash working capital reserve that may include but is not limited to, a combination of a loan or loans, a grant or grants, and funding the reserve through an initial or continuing rate increment.20.2. Test Period; Actual audited or finally closed experience for die most recent 12 month period ending on a calendar quarter available shall be used in preparing Statements A to G, inclusive. All adjustments for known and measurable changes in revenues and costs shall be clearly and fully explained.

Consideration of items treated differently for ratemaking purposes than for bookkeeping purposes should also be reflected as going-level adjustments.20.3.1.d. Pro forma adjustments should be used only to reflect the effect of the proposed rates on revenues and any related expense changes.20.3.2. Statement A - Schedule 1.

Any utility which participates in a consolidated state or federal income tax return must disclose such participation on this schedule.

When a consolidated and/or multi-jurisdictional state tax return is applicable, the calculation of the tax liability must be included on the face of die statement or as a separate schedule.20.3.6.b. If (because of "normalization" of timing differences between book and tax deductions, deferral of tax credits or any other reason) die provision for state or federal income tax calculated at going-level and/or proforma is different than a "flow through" calculation the effect of the difference must be fully disclosed and clearly explained on this schedule.20.3.6.c.

The bill analysis must be prepared in such manner as to provide ready calculations of revenues derived under rates in effect during the test year as well as revenue to be derived under proposed rates.20.6.2.

Statement E - Apportionment of Cost of Service - Statement E must be filed by all multi-jurisdictional utilities whose operations require an apportionment of cost of service between jurisdictions.

The functional categories used, and bases for distributing cost components between two or more functional categories must be clearly shown and fully explained. This statement must be presented in such form as to clearly indicate which cost components are directly assignable to a particular jurisdiction, class or group and which cost components require allocation. Where allocations are required, all allocation factors should be separately shown and explained with sufficient detail given to verify die computation of the factor. In the case of allocation between jurisdictions, allocation factors should be presented in a form that fully discloses each jurisdiction served and the relationship between allocations to each jurisdiction. If any volumes, demands, numbers, line mileage or other allocation factor determinants are either excluded in development of allocation factors or are included with another jurisdiction, class or group (rather than being shown separately) such treatment must be fully and clearly explained and justified.20.7.2. For each utility, cost apportionment procedures last approved by this Commission shall be the guide for procedures used in this Statement. Departure from the cost apportionment procedures last approved by this Commission shall be unacceptable; however, such departures may be shown in supplemental exhibits which must be filed in a separate addendum to the data prescribed by this rule. Any such exhibits should include a complete description of the proposed departures from cost apportionment procedures last approved by this Commission and a clear explanation of the underlying reasons indicating justification for such departures.20.7.3.

This schedule shall be filed to show annual cash flows from the income statement income accounts, less expenditures reflected in expense and tax accounts, less debt service expenditures and reserve funding.20.9. Statement G - Detail of Adjustments - All adjustments must be referenced to the explanations contained on this Statement. Adjustments should be sequentially numbered and grouped under the three adjustment headings used; Accounting, Going-Level and Proforma. 20.9.1 Grouping of two or more adjustments into a single net adjustment will not be permitted, provided that adjustments to expense categories that are spread across multiple accounts (such as payroll expense) may be shown as a single undistributed adjustment if the basis for die adjustment is a single across-the-board percentage multiplier. For single adjustments or undistributed adjustments the detail of adjustments must include the account number(s) and the book amount(s) to which the proposed adjustments relate.20.9.2. Where adjustments are based on calculations shown on other statements of supporting schedules provided for herein such basis for the adjustment should be indicated on this Statement. All calculations of adjustments not shown elsewhere should be shown with the explanation; however, should the calculation be so extraordinarily voluminous as to unduly lengthen and complicate this Statement, it may be omitted. In the case of omission of the detailed calculation of an adjustment the basis for the adjustment must be fully explained on this Statement and the detail of the calculation must be separately filed.20.9.3. The statements filed under this rule should not contain any adjustments that do not reflect known and quantifiable changes. Should a company desire to present other adjustments for the Commission's consideration they should be shown on supplemental sheets to the statements and schedules provided for herein and reflected in a separate going-level column added to the original statements and schedules. All such supplemental sheets should be grouped together as an addendum to the basic financial data prescribed by this rule.W. Va. Code R. § 150-2-20
