    ``(j) Deduction Adjustment To Allow Equivalent of Expensing For 
Certain Property Placed in Service in Taxable Years Beginning After

            ``(1) In general.--In the case of tangible property placed 
        in service in a taxable year beginning after December 31, 1992, 
        the deduction allowable under this section with respect to such 
        property for any taxable year (after the taxable year during 
        which the property is placed in service) shall be--
                    ``(A) the amount so allowable for such taxable year 
                without regard to this subsection, multiplied by
                    ``(B) the applicable neutral cost recovery ratio 
                for such taxable year.
        For purposes of subparagraph (A), paragraphs (1) and (2) of 
        section 168(b) shall be applied by substituting `150 percent' 
        for `200 percent'.
            ``(2) Applicable neutral cost recovery ratio.--For purposes 
        of paragraph (1), the applicable neutral cost recovery ratio 
        for any taxable year is the number determined by--
                    ``(A) dividing--
                            ``(i) the gross national product deflator 
                        for the calendar quarter ending in such taxable 
                        year which corresponds to the calendar quarter 
                        during which the property was placed in service 
                        by the taxpayer, by
                            ``(ii) the gross national product deflator 
                        for the calendar quarter during which the 
                        property was placed in service by the taxpayer, 
                        and
                    ``(B) then multiplying the number determined under 
                subparagraph (A) by the number equal to 1.035 to the 
                nth power where `n' is the number of full years in the 
                period beginning on the 1st day of the calendar quarter 
                during which the property was placed in service by the 
                taxpayer and ending on the day before the beginning of 
                the corresponding calendar quarter ending during such 
                taxable year.
        The applicable neutral cost recovery ratio shall not be taken 
        into account unless it is greater than 1. The applicable 
        neutral cost recovery ratio shall be rounded to the nearest 
        one-tenth of 1 percent.
            ``(3) Gross national product deflator.--For purposes of 
        paragraph (2), the gross national product deflator for any 
        calendar quarter is the implicit price deflator for the gross 
        national product for such quarter (as shown in the first 
        revision thereof).
            ``(4) Election not to have subsection apply.--This 
        subsection shall not apply to any property if the taxpayer 
        elects not to have this subsection apply to such property. Such 
        an election, once made, shall be irrevocable.''
    (b) Minimum Tax Treatment.--Paragraph (1) of section 56(a) of such 
Code is amended by adding at the end thereof the following new 
subparagraph:
                    ``(E) Use of Neutral Cost Recovery Ratio.--In the 
                case of tangible property placed in service in a 
                taxable year beginning after December 31, 1992, the 
                deduction allowable under this paragraph with respect 
                to such property for any taxable year (after the 
                taxable year during which the property is placed in 
                service) shall be--
                            ``(i) the amount so allowable for such 
                        taxable year without regard to this 
                        subparagraph, multiplied by
                            ``(ii) the applicable neutral cost recovery 
                        ratio for such taxable year (as determined 
                        under section 168(j)).
                This subparagraph shall not apply to any property with

                        shall be the same as the depreciation deduction 
                        allowable in computing alternative minimum 
                        taxable income for such taxable year.

                        the beginning of the taxpayer's first taxable
