(1)

Depreciation—

(A)

In general—

(i)

Property other than certain personal property— Except as provided in clause (ii), the depreciation deduction allowable under section 167 with respect to any tangible property placed in service after December 31, 1986, shall be determined under the alternative system of section 168(g). In the case of property placed in service after December 31, 1998, the preceding sentence shall not apply but clause (ii) shall continue to apply.

(ii)

150-percent declining balance method for certain property— The method of depreciation used shall be—

(I)

the 150 percent declining balance method,

(II)

switching to the straight line method for the 1st taxable year for which using the straight line method with respect to the adjusted basis as of the beginning of the year will yield a higher allowance.

The preceding sentence shall not apply to any section 1250 property (as defined in section 1250(c)) (and the straight line method shall be used for such section 1250 property) or to any other property if the depreciation deduction determined under section 168 with respect to such other property for purposes of the regular tax is determined by using the straight line method.

(B)

Exception for certain property— This paragraph shall not apply to property described in paragraph (1), (2), (3), or (4) of section 168(f), or in section 168(e)(3)(C)(iv).

(C)

Coordination with transitional rules—

(i)

In general— This paragraph shall not apply to property placed in service after December 31, 1986, to which the amendments made by section 201 of the Tax Reform Act of 1986 do not apply by reason of section 203, 204, or 251(d) of such Act.

(ii)

Treatment of certain property placed in service before 1987— This paragraph shall apply to any property to which the amendments made by section 201 of the Tax Reform Act of 1986 apply by reason of an election under section 203(a)(1)(B) of such Act without regard to the requirement of subparagraph (A) that the property be placed in service after December 31, 1986.

(D)

Normalization rules— With respect to public utility property described in section 168(i)(10), the Secretary shall prescribe the requirements of a normalization method of accounting for this section.

(B)

Loss allowed— If a loss is sustained with respect to any property described in subparagraph (A), a deduction shall be allowed for the expenditures described in subparagraph (A) for the taxable year in which such loss is sustained in an amount equal to the lesser of—

In the case of such a facility placed in service after December 31, 1998, such deduction shall be determined under section 168 using the straight line method.

(6)

Adjusted basis— The adjusted basis of any property to which paragraph (1) or (5) applies (or with respect to which there are any expenditures to which paragraph (2) or subsection (b)(2) applies) shall be determined on the basis of the treatment prescribed in paragraph (1), (2), or (5), or subsection (b)(2), whichever applies.

(7)

Section 87 not applicable— Section 87 (relating to alcohol fuel credit) shall not apply.

(b)
