PLR 201050010: IRS approved a revised nuclear decommissioning reserve funding schedule

Plain-English summary

The IRS reviewed a utility's proposed revised schedule of annual amounts to fund a nuclear power plant decommissioning reserve after the plant's operating license was extended. The taxpayer represented that it was the plant's indirect sole owner and had calculated the schedule using industry-based assumptions about investment returns, decommissioning costs, and the plant's useful life. The IRS concluded that the taxpayer was eligible, that the proposed schedule used reasonable assumptions, and that the schedule satisfied section 468A and its regulations. The approval was conditioned on the facts remaining unchanged and required future review if specified events occurred.

Dear ------------:

This letter responds to your request, dated ---------------------, for a mandatory review of a revised schedule of ruling amounts pursuant to § 468A(d) of the Internal Revenue Code and § 1.468A-3T(f)(1)(iv) of the temporary Income Tax Regulations with regard to a qualified nuclear decommissioning reserve fund that Taxpayer has established for the Plant and associated facilities. Taxpayer was previously granted schedules of ruling amounts, most recently on Date 1. This request is prompted by the fact that Commission X has issued an extension of the Plant’s nuclear operating license.

Taxpayer represents the facts and information relating to its request for a revised schedule of ruling amounts as follows:

Taxpayer is the indirect sole owner of the Plant, which is situated in Location.
Taxpayer files a consolidated federal income tax return with its affiliated companies and is under the audit jurisdiction of the Industry Director. The method of decommissioning the Plant is Method.

On Date 2, Commission X issued Order in which it extended the operating license of Plant from Date 3 to Date 4.

Based upon an Independent Study prepared based on the assumption that the license extension would be granted, it is estimated that Fund assets will earn an after- tax rate of return of a percent. The total cost of decommissioning the Plant is estimated to be $b (in Year 1 dollars). This base cost of decommissioning Plant is escalated at a c percent yearly rate, resulting in a total future cost of decommissioning the Plant of $d (in Year 2 through Year 3 dollars). Under ratemaking assumptions used during the first proceeding before applicable public utility commissions, the Plant would no longer be included in rate base in Year 1. As a result of the extension of the Plant’s operating license to Year 2, the estimated useful life of the Plant, as well as the funding period for the Plant ends in Year 2. The estimated taxable year in which substantial completion of decommissioning the Plant will occur is Year 3.

Section 468A(a), as amended by the Energy Tax Incentives Act of 2005 (the Act), Pub. L. 109-58, 119 Stat. 594, allows an electing taxpayer to deduct payments made to a nuclear decommissioning reserve fund. Section 468A(b) limits the amount that may be paid into the nuclear decommissioning fund in any year to the ruling amount applicable to that year.

Section 468A(d)(1) provides that no deduction shall be allowed for any payment to the nuclear decommissioning fund unless the taxpayer requests and receives from the Secretary a schedule of ruling amounts. The “ruling amount” for any tax year is defined under § 468A(d)(2) as the amount which the Secretary determines to be necessary to fund the total nuclear decommissioning cost of that nuclear power plant over the estimated useful life of the plant. This term is further defined to include the amount necessary to prevent excessive funding of nuclear decommissioning costs or funding of these costs at a rate more rapid than level funding, taking into account such

PLR-111656-10

discount rates as the Secretary deems appropriate.

Section 468A(h) provides that a taxpayer shall be deemed to have made a payment to the nuclear decommissioning fund on the last day of a taxable year if the payment is made on account of such taxable year and is made within 2½ months after the close of the tax year. This section applies to payments made pursuant to either a schedule of ruling amounts or a schedule of deduction amounts.

Section 1.468A-1T(a) provides that an eligible taxpayer may elect to deduct nuclear decommissioning costs under section 468A of the Code. An “eligible taxpayer,” as defined under § 1.468A-1T(b)(1) of the regulations, is a taxpayer that has a “qualifying interest” in any portion of a nuclear power plant. A qualifying interest is, among other things, a direct ownership interest.

Section 1.468A-2T(b)(1) provides that the maximum amount of cash payments made (or deemed made) to a nuclear decommissioning fund during any tax year shall not exceed the ruling amount applicable to the nuclear decommissioning fund for such taxable year. The limitation on the amount of cash payments for purposes of § 1.468A-2T(b)(1) does not apply to any “special transfer” permitted under § 1.468A-8T.

Section 1.468A-3T(a)(1) provides that, in general, a schedule of ruling amounts for a nuclear decommissioning fund is a ruling specifying annual payments that, over the tax years remaining in the “funding period” as of the date the schedule first applies, will result in a projected balance of the nuclear decommissioning fund as of the last day of the funding period equal to (and in no event more than) the “amount of decommissioning costs allocable to the fund”.

Section 1.468A-3T(a)(2) provides that, to the extent consistent with the principles and provisions of this section, each schedule of ruling amounts shall be based on reasonable assumptions concerning the after-tax rate of return to be earned by the amounts collected for decommissioning, the total estimated cost of decommissioning the nuclear plant, and the frequency of contributions to a nuclear decommissioning fund for a taxable year. Under § 1.468A-3T(a)(3), the Internal Revenue Service shall provide a schedule of ruling amounts identical to the schedule proposed by the taxpayer, but no such schedule shall be provided by the Service unless the taxpayer's proposed schedule is consistent with the principles and provisions of that section.

Section 1.468A-3T(a)(4) provides that the taxpayer bears the burden of demonstrating that the proposed schedule of ruling amounts is consistent with the principles of the regulations and that it is based on reasonable assumptions. That section also provides additional guidance regarding how the Service will determine whether a proposed schedule of ruling amounts is based on reasonable assumptions. For example, if a public utility commission established or approved the currently applicable rates for the furnishing or sale by the taxpayer of electricity from the plant,

PLR-111656-10
4

the taxpayer can generally satisfy this burden of proof by demonstrating that the schedule of ruling amounts is calculated using the assumptions used by the public utility commission in its most recent order. In addition, a taxpayer that owns an interest in a deregulated nuclear plant may submit assumptions used by a public utility commission that formerly had regulatory jurisdiction over the plant as support for the assumptions used in calculating the taxpayer's proposed schedule of ruling amounts, with the understanding that the assumptions used by the public utility commission may be given less weight if they are out of date or were developed in a proceeding for a different taxpayer. The use of other industry standards, such as the assumptions underlying the taxpayer's most recent financial assurance filing with the -------, are described by the temporary regulations as an alternative means of demonstrating that the taxpayer has calculated its proposed schedule of ruling amounts on a reasonable basis. Section 1.468A-3T(a)(4) further provides that consistency with financial accounting statements is not sufficient, in the absence of other supporting evidence, to meet the taxpayer's burden of proof.

Section 1.468A-3T(b)(1) provides that, in general, the ruling amount for any tax year in the funding period shall not be less than the ruling amount for any earlier tax year. Under § 1.468A-3T(c)(1), the funding period begins on the first day of the first tax year for which a deductible payment is made to the nuclear decommissioning fund and ends on the last day of the taxable year that includes the last day of the estimated useful life of the nuclear power plant to which the fund relates.

Section 1.468A-3T(c)(2) provides rules for determining the estimated useful life of a nuclear plant for purposes of § 468A. In general, under § 1.468A-3T(c)(2)(i)(A), if the plant was included in rate base for ratemaking purposes for a period prior to January 1, 2006, the date used in the first such ratemaking proceeding as the estimated date on which the nuclear plant will no longer be included in the taxpayer's rate base is the end of the estimated useful life of the nuclear plant. Section 1.468A-3T(c)(2)(i)(B) provides that, if the nuclear plant is not described in § 1.468A-3T(c)(2)(i)(A), the last day of the estimated useful life of the nuclear plant is determined as of the date the plant is placed in service. Under § 1.468A-3T(c)(2)(i)(C), any reasonable method may be used in determining the estimated useful life of a nuclear power plant that is not described in § 1.468A-3T(c)(2)(i)(A).

Section 1.468A-3T(d)(1) provides that the amount of decommissioning costs allocable to a nuclear decommissioning fund is the taxpayer's share of the total estimated cost of decommissioning the nuclear power plant. Section 1.468A-3T(d)(3) provides that a taxpayer's share of the total estimated cost of decommissioning a nuclear power plant equals the total estimated cost of decommissioning such plant multiplied by the taxpayer's qualifying interest in the plant.

Section 1.468A-3T(e)(2) enumerates the information required to be contained in a request for a schedule of ruling amounts filed by a taxpayer in order to receive a ruling

PLR-111656-10

amount for any taxable year.

Section 1.468A-3T(f)(1) requires a taxpayer that has obtained a schedule of ruling amounts pursuant to § 1.468A-3T(e) to file a request for a revised schedule of ruling amounts on or before the deemed payment deadline date for the 10th taxable year that begins after the taxable year in which the most recent schedule of ruling amounts was received. If the taxpayer calculated its most recent schedule of ruling amounts on any basis other than an order issued by a public utility commission, the taxpayer must file a request for a revised schedule of ruling amounts on or before the deemed payment deadline date for the 5th taxable year that begins after the taxable year in which the most recent schedule of ruling amounts was received.

Section 1.468A-3T(f)(2) provides that any taxpayer that has previously obtained a schedule of ruling amounts can request a revised schedule of ruling amounts. Such a request must be made in accordance with the rules of § 1.468A-3T(e). The Internal Revenue Service shall not provide a revised schedule of ruling amounts applicable to a taxable year in response to a request for a schedule of ruling amounts that is filed after the deemed payment deadline date for such taxable year.

We have examined the representations and information submitted by the Taxpayer in relation to the requirements set forth in § 468A and the regulations thereunder. Based solely upon these representations of the facts, we reach the following conclusions:

1. Taxpayer has a qualifying interest in the Plant and is, therefore, an eligible
   taxpayer under § 1.468A-1T(b)(1) of the regulations.

2. Taxpayer, as sole owner of the Plant, has calculated its share of the total
   decommissioning costs under § 1.468A-3T(d)(3) of the regulations.

3. The proposed schedule of ruling amounts was derived by following the
   assumptions contained in the Independent Commissioning Study that Taxpayer has represented is a standard type study used in the industry. Based on that representation, Taxpayer has demonstrated, pursuant to § 1.468A-3T(a)(4), that the proposed schedule of ruling amounts is based on reasonable assumptions and is consistent with the principles of § 468A and the regulations thereunder.

4. The maximum amount of cash payments made (or deemed made) to the Fund
   during any tax year is restricted to the ruling amount applicable to the Fund, as set forth under § 1.468A-2T(b)(1) of the regulations.

Based solely on the determinations above, we conclude that Taxpayer's proposed schedule of ruling amounts satisfies the requirements of § 468A of the Code.

----------------------------------------
-------

Approval of the schedule of ruling amounts is contingent on there being no change in the facts and circumstances, known or assumed, at the time the current ruling is issued. If any of the events described in § 1.468A-3T(f)(1) occur in future years, the taxpayer must request a review and revision of the schedule of ruling amounts. Generally, the taxpayer is required to file such a request on or before the deemed payment deadline date for the first taxable year in which the rates reflecting such action became effective. When no such event occurs, the taxpayer must file a request for a revised schedule of ruling amounts on or before the deemed payment deadline of the tenth taxable year following the close of the tax year in which the most recent schedule of ruling amounts was received.

Except as specifically determined above, no opinion is expressed or implied concerning the Federal income tax consequences of the transaction described above.

This ruling is directed only to the taxpayer who requested it. Section 6110(k)(3) of the Code provides it may not be used or cited as precedent. In accordance with the power of attorney on file with this office a copy of this letter is being sent to the Director. Pursuant to § 1.468A-7T(a), a copy of this letter must be attached (with the required Election Statement) to the taxpayer's federal income tax return for each tax year in which the taxpayer claims a deduction for payments made to the Fund.

Sincerely,
