A carrier that files for rates pursuant to § 342.2(a) or § 342.4(a) of this chapter, or a carrier described in § 342.0(b) that files to establish or change rates by filing cost, revenue, and throughput data supporting such rates, other than pursuant to a Commission-approved settlement, must file the following statements, schedules, and supporting workpapers. The statement, schedules, and workpapers must be based upon an appropriate test period.
(a) Base and test periods defined. (1) For a carrier which has been in operation for at least 12 months:
(i) A base period must consist of 12 consecutive months of actual experience. The 12 months of experience must be adjusted to eliminate nonrecurring items (except minor accounts). The filing carrier may include appropriate normalizing adjustments in lieu of nonrecurring items.
(ii) A test period must consist of a base period adjusted for changes in revenues and costs which are known and are measurable with reasonable accuracy at the time of filing and which will become effective within nine months after the last month of available actual experience utilized in the filing. For good cause shown, the Commission may allow reasonable deviation from the prescribed test period.
(2) For a carrier which has less than 12 months' experience, the test period may consist of 12 consecutive months ending not more than one year from the filing date. For good cause shown, the Commission may allow reasonable deviation from the prescribed test period.
(3) For a carrier which is establishing rates for new service, the test period will be based on a 12-month projection of costs and revenues.
(b) Cost-of-service summary schedule. This schedule must contain the following information:
(1) Total carrier cost of service for the test period.
(2) Throughput for the test period in both barrels and barrel-miles.
(3) For filings pursuant to § 342.4(a) of this chapter, the schedule must include the proposed rates, the rates which would be permitted under § 342.3 of this chapter, and the revenues to be realized from both sets of rates.

This statement must set forth the rate base for return purposes from Statement E in paragraph (c)(5) of this section and must also state the claimed rate of return and the application of the claimed rate of return to the overall rate base. The claimed rate of return must consist of a weighted cost of capital, combining the rate of return on debt capital and the real rate of return on equity capital. Items used in the computations or derived on this statement must include deferred earnings, equity ratio, debt ratio, weighted cost of capital, and costs of debt and equity.
(4) Statement D—income taxes. This statement must set forth the income tax computation. Items used in the computations or derived on this statement must show: return allowance, interest expense, equity return, annual amortization of deferred earnings, depreciation on equity AFUDC, underfunded or overfunded ADIT amortization amount, taxable income, tax factor, and income tax allowance.
(5) Statement E—rate base. This statement must set forth the return rate base. Items used in the computations or derived on this statement must include beginning balances of the rate base at December 31, 1983, working capital (including materials and supplies, prepayments, and oil inventory), accrued depreciation on carrier plant, accrued depreciation on rights of way, and accumulated deferred income taxes; and adjustments and end balances for original cost of retirements, interest during construction, AFUDC adjustments, original cost of net additions and retirements from land, original cost of net additions and retirements from rights of way, original cost of plant additions, original cost accruals for depreciation, AFUDC accrued depreciation adjustment, original cost depreciation accruals added to rights of way, net charge for retirements from accrued depreciation, accumulated deferred income taxes, changes in working capital (including materials and supplies, prepayments, and oil inventory), accrued deferred earnings, annual amortization of accrued deferred earnings, and amortization of starting rate base write-up.

This statement must set forth the computation of allowances for funds used during construction (AFUDC) including the AFUDC for each year commencing in 1984 and a summary of AFUDC and AFUDC depreciation for the years 1984 through the test year.
(7) Statement G—revenues. This statement must set forth the gross revenues for the actual 12 months of experience as computed under both the presently effective rates and the proposed rates. If the presently effective rates are not at the maximum ceiling rate established under § 342.3 of this chapter, then gross revenues must also be computed and set forth as if the ceiling rates were effective for the 12 month period.
