# Limitation in case of certain regulated companies.
**AGENCY:**
Internal Revenue Service (IRS), Treasury.
**ACTION:**
Correcting amendment.
**SUMMARY:**
This document contains a correction to final regulations (TD 9387) that were published in the *Federal Register* on Thursday, March 20, 2008 (73 FR 14934), providing 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.
**DATES:**
This correction is effective April 7, 2008.
