Sec. 35.24  Tax normalization for public utilities.

    (a) Applicability. (1) Except as provided in subparagraph (2) of 
this paragraph, this section applies, with respect to rate schedules 
filed under Sec. Sec. 35.12 and 35.13 of this part, to the ratemaking 
treatment of the tax effects of all transactions for which there are 
timing differences.
    (2) This section does not apply to the following timing differences:
    (i) Differences that result from the use of accelerated 
depreciation;
    (ii) Differences that result from the use of Class Life Asset 
Depreciation Range (ADR) provisions of the Internal Revenue Code;
    (iii) Differences that result from the use of accelerated 
amortization provisions on certified defense and pollution control 
facilities;
    (iv) Differences that arise from recognition of extraordinary 
property losses as a current expense for tax purposes but as a deferred 
and amortized expense for book purposes;
    (v) Differences that arise from recognition of research, 
development, and demonstration expenditures as a current expense for tax 
purposes but as a deferred and amortized expense for book purposes;
    (vi) Differences that result from different tax and book reporting 
of deferred gains or losses from disposition of utility plant;
    (vii) Differences that result from the use of the Asset Guideline 
Class ``Repair Allowance'' provision of the Internal Revenue Code;
    (viii) Differences that result from recognition of purchased gas 
costs as a current expense for tax purposes but as a deferred expense 
for book purposes.

(See Order 13, issued October 18, 1978; Order 203, issued May 29, 1958; 
Order 204, issued May 29, 1958; Order 404, issued May 15, 1970; Order 
408, issued August 26, 1970; Order 432, issued April 23, 1971; Order

Order 566, issued June 3, 1977; Opinion 578, issued June 3, 1970; and 
Opinion 801, issued May 31, 1977.)

    (b) General rules--(1) Tax normalization required. (i) A public 
utility must compute the income tax component of its cost of service by 
using tax normalization for all transactions to which this section 
applies.
    (ii) Except as provided in paragraph (c) of this section, 
application of tax normalization by a public utility under this section 
to compute the income tax component will not be subject to case-by-case 
adjudication.
    (2) Reduction of, and addition to, rate base. (i) The rate base of a 
public utility using tax normalization under this section must be 
reduced by the balances that are properly recordable in Account 281, 
``Accumulated deferred income taxes-accelerated amortization property;'' 
Account 282, ``Accumulated deferred income taxes--other property;'' and 
Account 283, ``Accumulated deferred income taxes--other.'' Balances that 
are properly recordable in Account 190, ``Accumulated deferred income 
taxes,'' must be treated as an addition to rate base.
    (ii) Such rate base reductions or additions must be limited to 
deferred taxes related to rate base, construction or other 
jurisdictional activities.
    (iii) If a public utility uses an approved purchased gas adjustment 
clause or a research, development and demonstration tracking clause, the 
rate base reductions or additions required under this subparagraph must 
apply only to the extent that the balances in Account 190 and Accounts 
281 through 283 are not used, for purposes of calculating carrying 
charges, as an offset to balances properly recordable in Account 188, 
``Research development and demonstration expenditures,'' or Account 191, 
``Unrecovered purchased gas costs.''
    (c) Special rules. (1) This paragraph applies:
    (i) If the public utility has not provided deferred taxes in the 
same amount that would have accrued had tax normalization been applied 
for the tax effects of timing difference transactions originating at any 
time prior to the test period; or
    (ii) If, as a result of changes in tax rates, the accumulated 
provision for deferred taxes becomes deficient in or in excess of 
amounts necessary to meet future tax liabilities as determined by 
application of the current tax rate to all timing difference 
transactions originating in the test period and prior to the test 
period.
    (2) The public utility must compute the income tax component in its 
cost of service by making provision for any excess or deficiency in 
deferred taxes described in subparagraphs (1)(i) or (1)(ii) of this 
paragraph.
    (3) The public utility must apply a Commission-approved ratemaking 
method made specifically applicable to the public utility for 
determining the cost of service provision described in subparagraph (2) 
of this paragraph. If no Commission-approved ratemaking method has been 
made specifically applicable to the public utility, then the public 
utility must use some ratemaking method for making such provision, and 
the appropriateness of this method will be subject to case-by-case 
determination.
    (d) Definitions. For purposes of this section, the term:
    (1) Tax normalization means computing the income tax component as if 
the amounts of timing difference transactions recognized in each period 
for ratemaking purposes were also recognized in the same amount in each 
such period for income tax purposes.
    (2) Timing differences means differences between amounts of expenses 
or revenues recognized for income tax purposes and amounts of expenses 
or revenues recognized for ratemaking purposes, which differences arise 
in one time period and reverse in one or more other time periods so that 
the total amounts of expenses or revenues recognized for income tax 
purposes and for ratemaking purposes are equal.
    (3) Commission-approved ratemaking method means a ratemaking method 
approved by the Commission in a final decision including approval of a 
settlement agreement containing a ratemaking method only if such 
settlement

[[Page 282]]

agreement applies that method beyond the effective term of the 
settlement agreement.
    (4) Income tax purposes means for the purpose of computing income 
tax under the provisions of the Internal Revenue Code or the income tax 
provisions of the laws of a State or political subdivision of a State 
(including franchise taxes).
    (5) Income tax component means that part of the cost of service that 
covers income tax expenses allowable by the Commission.
    (6) Ratemaking purposes means for the purpose of fixing, modifying, 
approving, disapproving or rejecting rates under the Federal Power Act 
or the Natural Gas Act.
    (7) Tax effect means the tax reduction or addition associated with a 
specific expense or revenue transaction.
    (8) Transaction means an activity or event that gives rise to an 
accounting entry that is used in determining revenues or expenses.
