(b) A detailed description of the unit of property under the taxpayer’s present and proposed methods of accounting for determining when the property is disposed of by the taxpayer for depreciation purposes (when depreciation ends);
(c) A detailed description of how the taxpayer determined the unit of property under its present method of accounting for determining when the property is disposed of by the taxpayer for depreciation purposes and will determine the unit of property under its proposed method of accounting for determining when the property is disposed of by the taxpayer for depreciation purposes. If this proposed unit of property is not determined using only the functional interdependence standard ( see, e.g., Armstrong World Industries, Inc. v. Commissioner, T.C. Memo. 1991–326, aff’d, 974 F.2d 422 (3 rd Cir. 1992); Hawai- ian Independent Refinery, Inc. v. United States, 697 F.2d 1063, 1069 (Fed.

(d) A statement as to whether the taxpayer’s proposed unit of property for determining when the property is disposed of by the taxpayer for depreciation purposes is the same as the taxpayer’s present unit of property for determining when the property is placed in service by the tax
payer (when depreciation begins). If not, also provide the unit of property for determining when the property is placed in service by the taxpayer and explain why the taxpayer is using a different unit of property for determining when the property is placed in service; and
(e) if any item of property is public utility property within the meaning of § 168(i)(10) or former § 167(l)(3)(A), as applicable, a statement providing that the taxpayer agrees to the following additional terms and conditions:
(i) a normalization method of accounting (within the meaning of former § 167(l)(3)(G), former § 168(e)(3)(B), or § 168(i)(9), as applicable) will be used for the public utility property subject to the application;
(ii) as of the beginning of the year of change, the taxpayer will adjust its deferred tax reserve account or similar reserve account in the taxpayer’s regulatory books of account by the amount of the deferral of federal income tax liability associated with the § 481(a) adjustment applicable to the public utility property subject to the application; and
(iii) within 30 calendar days of filing the federal income tax return for the year of change, the taxpayer will provide a copy of the completed application to any regulatory body having jurisdiction over the public utility property subject to the application.
(3) No ruling on unit of property . The consent granted under this revenue procedure for this change is not a determination by the Commissioner that the taxpayer is using the appropriate unit of property for determining when the property is placed in service or disposed of by the taxpayer for depreciation purposes and does not create any presumption that the proposed unit of property is permissible for depreciation purposes. The director will ascertain whether the taxpayer’s determination of its unit of property for depreciation purposes is correct.
