§ 1.168(i)-3 Treatment of excess deferred income tax reserve upon disposition of deregulated public utility property.

This section provides rules for the application of section 203(e) of the Tax Reform Act of 1986, Public Law 99-514 (100 Stat. 2146) to a taxpayer with respect to public utility property (within the meaning of section 168(i)(10)) that ceases, whether by disposition, deregulation, or otherwise, to be public utility property with respect to the taxpayer and that is not described in paragraph (a)(2) of this section (deregulated public utility property). (2) Exceptions. This section does not apply to the following property: (i) Property that ceases to be public utility property with respect to the taxpayer on account of an ordinary retirement within the meaning of § 1.167(a)-11(d)(3)(ii). (ii) Property transferred by the taxpayer if after the transfer the property is public utility property of the transferee and the taxpayer's excess tax reserve with respect to the property (within the meaning of section 203(e) of the Tax Reform Act of 1986) is treated as an excess tax reserve of the transferee with respect to the property. (b) Amount of reduction. If public utility property of a taxpayer becomes deregulated public utility property to which this section applies, the reduction in the taxpayer's excess tax reserve permitted under section 203(e) of the Tax Reform Act of 1986 is equal to the amount by which the reserve could be reduced under that provision if all such property had remained public utility property of the taxpayer and the taxpayer had continued use of its normalization method of accounting with respect to such property.
