Application of Normalization Accounting Rules to Balances of Excess Deferred Income Taxes and Accumulated Deferred Investment Tax Credits of Public Utilities Whose Assets Cease To Be Public Utility Property

This document contains final regulations that provide guidance on the normalization requirements applicable to public utilities that benefit (or have benefited) from accelerated depreciation methods or from the investment tax credit permitted under pre-1991 law. These regulations permit a utility whose assets cease, whether by disposition, deregulation, or otherwise, to be public utility property with respect to the utility (deregulated public utility property) to return to its ratepayers the normalization reserve for excess deferred income taxes (EDFIT) with respect to those assets and, in certain circumstances, also permit the return of part or all of the reserve for accumulated deferred investment tax credits (ADITC) with respect to those assets.
