OPINION ON PETITION FOR REHEARING

This court issued an unpublished opinion in this case affirming the district court’s decision, with a dissent. The appellant Florida Progress Corporation has petitioned for rehearing,’ asking in part that this court publish its opinion in order to provide guidance on the second issue Florida Progress raises — the immediate deduc-tibility of trenching costs. The petition is GRANTED to that extent we vacate our unpublished opinion and substitute the following opinion, for publication. The petition is otherwise DENIED.

Florida Progress Corporation, which the parties refer to as Florida Power, appeals following summary judgment against it in its suit for recovery of taxes paid for the tax years 1982 through 1985. Florida Power presents two issues: first, whether under 26 U.S.C. § 118(b) (which was repealed in 1986), it was entitled to exclude from income certain fees paid by customers to cover the marginal costs of burying electric lines serving the customers’ premises, rather than stringing the lines overhead; and second, whether trenching costs (roughly speaking, the marginal costs of burying the lines rather than running them overhead) were properly expensed under 26 U.S.C. § 162(a) rather than capitalized and depreciated as contemplated by 26 U.S.C. § 263. Having reviewed the authorities the parties cite and considered the parties’ arguments, we agree with the district court’s analysis of these issues and affirm for the reasons stated in its thorough and well-reasoned opinion, which is published at 156 F.Supp.2d 1265 (2001).

AFFIRMED.

concurring in part and dissenting in part:

I agree with majority’s decision to affirm on the first issue concerning 26 *1314U.S.C. § 118(b). I respectfully disagree, however, with the majority’s decision on the second issue. I would reverse the district court insofar as it held that Appellant’s trenching costs could not be deducted per 26 U.S.C. § 162(a), but rather had to be capitalized per 26 U.S.C. § 263. It is true that the Internal Revenue Code bars a deduction for “[a]ny amount paid out ... for permanent improvements or better-ments”, but this bar applies only to improvements or betterments that are “made to increase the value of any property or estate.” 26 U.S.C. § 263(a)(1) (emphasis added). Due to the regulations and mandated accounting procedures of the Florida Public Service Commission (FPSC), it is legally impossible for Appellant’s trenching costs to ever result in an increase in the value of Appellant’s property or estate. The district court failed to give sufficient weight to this regulatory aspect of Appellant’s business. See Comm’r of Internal Revenue v. Idaho Power Co., 418 U.S. 1, 94 S.Ct. 2757, 2765, 41 L.Ed.2d 535 (1974) (holding that “[although agency-imposed compulsory accounting practices do not necessarily dictate tax consequences, they are not irrelevant and may be accorded some significance” (citation omitted)).1 For that reason, I respectfully dissent from the majority’s decision to affirm the district court’s grant of summary judgment for Appellee with regard to the de-ductibility of Appellant’s' trenching costs.
