        166(a) shall be a net operating loss carryback to each of the
        10 taxable years preceding the taxable year of the loss and a
        net operating loss carryover to each of the 5 taxable years
        following the taxable year of such loss.

            Subparagraph (A)(i) shall be applied by substituting ''3
          taxable years'' for ''2 taxable years'' (FOOTNOTE 1) with
          respect to the portion of the net operating loss for the
          taxable year which is an eligible loss with respect to the
           taxpayer.
       (FOOTNOTE 1) So in original.  Probably should be '' '3 taxable
        years' for '2 taxable years' ''.
          (ii) Eligible loss
            For purposes of clause (i), the term ''eligible loss''
          means -
              (I) in the case of an individual, losses of property

              (III) in the case of a taxpayer engaged in the trade or
            business of farming (as defined in section 263A(e)(4)), net
            operating losses attributable to such Presidentially
            declared disasters.

          subsection (i)).
          (iii) Small business
            For purposes of this subparagraph, the term ''small
          business'' means a corporation or partnership which meets the
          gross receipts test of section 448(c) for the taxable year in
          which the loss arose (or, in the case of a sole
          proprietorship, which would meet such test if such
          proprietorship were a corporation).
          (iv) Coordination with paragraph (2)
            For purposes of applying paragraph (2), an eligible loss
          for any taxable year shall be treated in a manner similar to
          the manner in which a specified liability loss is treated.
        (G) Farming losses
          In the case of a taxpayer which has a farming loss (as
        defined in subsection (i)) for a taxable year, such farming
        loss shall be a net operating loss carryback to each of the 5
        taxable years preceding the taxable year of such loss.
        (H) In the case of a net 
         operating loss for any taxable year ending during 2001 
         or 2002, subparagraph (A)(i) shall be applied by

                      loss carryback to each of the 5 taxable years 
                      preceding the taxable year of such loss to the 
                      extent that such loss does not exceed 20 percent

                                to the taxable year in which such net 
                                operating loss arises or results in a 
                                net operating loss carryback shall be

          (v) DEFINITIONS- For purposes of this subparagraph--
             (I) ELECTRIC TRANSMISSION PROPERTY CAPITAL EXPENDITURES- The 
              term `electric transmission property capital expenditures' 
              means any expenditure, chargeable to capital account, made by 
              the taxpayer which is attributable to electric transmission 
              property used by the taxpayer in the transmission at 69 or 
              more kilovolts of electricity for sale. Such term shall not 
              include any expenditure which may be refunded or the purpose 
              of which may be modified at the option of the taxpayer so as 
              to cease to be treated as an expenditure within the meaning 
              of such term.
             (II) POLLUTION CONTROL FACILITY CAPITAL EXPENDITURES- The term 
              `pollution control facility capital expenditures' means any 
              expenditure, chargeable to capital account, made by an 
              electric utility company (as defined in section 2(3) of the 
              Public Utility Holding Company Act (15 U.S.C. 79b(3)), as in 
              effect on the day before the date of the enactment of the 
              Energy Tax Incentives Act of 2005) which is attributable to a 
              facility which will qualify as a certified pollution control 
              facility as determined under section 169(d)(1) by striking  
              `before January 1, 1976,' and by substituting `an 
              identifiable' for `a new identifiable'. Such term shall not 
              include any expenditure which may be refunded or the purpose 
              of which may be modified at the option of the taxpayer so as 
              to cease to be treated as an expenditure within the meaning 
              of such term.

      (2) Amount of carrybacks and carryovers
        The entire amount of the net operating loss for any taxable
      year (hereinafter in this section referred to as the ''loss
      year'') shall be carried to the earliest of the taxable years to
      which (by reason of paragraph (1)) such loss may be carried.  The
      portion of such loss which shall be carried to each of the other
      taxable years shall be the excess, if any, of the amount of such
      loss over the sum of the taxable income for each of the prior
      taxable years to which such loss may be carried.  For purposes of
      the preceding sentence, the taxable income for any such prior
      taxable year shall be computed -
          (A) with the modifications specified in subsection (d) other
        than paragraphs (1), (4), and (5) thereof, and
          (B) by determining the amount of the net operating loss
        deduction without regard to the net operating loss for the loss
        year or for any taxable year thereafter,
      and the taxable income so computed shall not be considered to be
      less than zero.
      (3) Election to waive carryback
        Any taxpayer entitled to a carryback period under paragraph (1)
      may elect to relinquish the entire carryback period with respect
      to a net operating loss for any taxable year.  Such election
      shall be made in such manner as may be prescribed by the
      Secretary, and shall be made by the due date (including
      extensions of time) for filing the taxpayer's return for the
      taxable year of the net operating loss for which the election is
      to be in effect.  Such election, once made for any taxable year,
      shall be irrevocable for such taxable year.
    (c) Net operating loss defined
      For purposes of this section, the term ''net operating loss''
    means the excess of the deductions allowed by this chapter over the
    gross income.  Such excess shall be computed with the modifications
    specified in subsection (d).
    (d) Modifications
      The modifications referred to in this section are as follows:
      (1) Net operating loss deduction
        No net operating loss deduction shall be allowed.

        allowed.
      (3) Deduction for personal exemptions
        No deduction shall be allowed under section 151 (relating to
      personal exemptions).  No deduction in lieu of any such deduction
      shall be allowed.
      (4) Nonbusiness deductions of taxpayers other than corporations
        In the case of a taxpayer other than a corporation, the
      deductions allowable by this chapter which are not attributable
      to a taxpayer's trade or business shall be allowed only to the
      extent of the amount of the gross income not derived from such
      trade or business.  For purposes of the preceding sentence -
          (A) any gain or loss from the sale or other disposition of -
            (i) property, used in the trade or business, of a character
          which is subject to the allowance for depreciation provided
          in section 167, or
            (ii) real property used in the trade or business,
        shall be treated as attributable to the trade or business;
          (B) the modifications specified in paragraphs (1), (2)(B),
        and (3) shall be taken into account;
          (C) any deduction for casualty or theft losses allowable

        as attributable to the trade or business; and

        attributable to contributions which are made on behalf of an
        individual who is an employee within the meaning of section
        401(c)(1) shall not be treated as attributable to the trade or
        business of such individual.
      (5) Computation of deduction for dividends received, etc.
        The deductions allowed by sections 243 (relating to dividends
      received by corporations), 244 (relating to dividends received on
      certain preferred stock of public utilities), and 245 (relating
      to dividends received from certain foreign corporations) shall be
      computed without regard to section 246(b) (relating to limitation
      on aggregate amount of deductions); and the deduction allowed by
      section 247 (relating to dividends paid on certain preferred
      stock of public utilities) shall be computed without regard to
      subsection (a)(1)(B) of such section.
      (6) Modifications related to real estate investment trusts
        In the case of any taxable year for which part II of subchapter
      M (relating to real estate investment trusts) applies to the
      taxpayer -
          (A) the net operating loss for such taxable year shall be
        computed by taking into account the adjustments described in
        section 857(b)(2) (other than the deduction for dividends paid
        described in section 857(b)(2)(B)); and
          (B) where such taxable year is a ''prior taxable year''
        referred to in paragraph (2) of subsection (b), the term
        ''taxable income'' in such paragraph shall mean ''real estate
        investment trust taxable income'' (as defined in section
        857(b)(2)).
      (7) Manufacturing deduction.--The deduction under section 
          199 shall not be allowed.
    (e) Law applicable to computations
      In determining the amount of any net operating loss carryback or
    carryover to any taxable year, the necessary computations involving
    any other taxable year shall be made under the law applicable to
    such other taxable year.
    (f) Rules relating to specified liability loss
      For purposes of this section -
      (1) In general
        The term ''specified liability loss'' means the sum of the
      following amounts to the extent taken into account in computing
      the net operating loss for the taxable year:
          (A) Any amount allowable as a deduction under section 162 or
        165 which is attributable to -
            (i) product liability, or
            (ii) expenses incurred in the investigation or settlement
          of, or opposition to, claims against the taxpayer on account
          of product liability.
          (B)(i) Any amount allowable as a deduction under this chapter
        (other than section 468(a)(1) or 468A(a)) which is in
        satisfaction of a liability under a Federal or State law
        requiring -
            (I) the reclamation of land,
            (II) the decommissioning of a nuclear power plant (or any
          unit thereof),
            (III) the dismantlement of a drilling platform,
            (IV) the remediation of environmental contamination, or
            (V) a payment under any workers compensation act (within
          the meaning of section 461(h)(2)(C)(i)).
          (ii) A liability shall be taken into account under this
        subparagraph only if -
            (I) the act (or failure to act) giving rise to such
          liability occurs at least 3 years before the beginning of the
          taxable year, and
            (II) the taxpayer used an accrual method of accounting
          throughout the period or periods during which such act (or
          failure to act) occurred.
      (2) Limitation
        The amount of the specified liability loss for any taxable year
      shall not exceed the amount of the net operating loss for such
      taxable year.
      (3) Special rule for nuclear powerplants
        Except as provided in regulations prescribed by the Secretary,
      that portion of a specified liability loss which is attributable

      (b)(1)(C), be carried back to each of the taxable years during
      the period -
          (A) beginning with the taxable year in which such plant (or

          (B) such injury, harm, or damage arises after the taxpayer
        has completed or terminated operations with respect to, and has
        relinquished possession of, such product.
      (5) Coordination with subsection (b)(2)
        For purposes of applying subsection (b)(2), a specified
      liability loss for any taxable year shall be treated as a
      separate net operating loss for such taxable year to be taken

      loss for such taxable year.
      (6) Election
        Any taxpayer entitled to a 10-year carryback under subsection
