    OPINION
    ¶1           In these consolidated appeals, petitioners, the State of Illinois, ex rel. Lisa
    Madigan, Attorney General of the State of Illinois (People), and the Citizens Utility
    Board (CUB) (collectively petitioners), appeal from an order of the Illinois Commerce
    Commission (Commission) determining that respondent, Commonwealth Edison
    (ComEd), was entitled to calculate interest on the full amount of under collected revenues
    pursuant to the annual reconciliation provisions of the Energy Infrastructure
    Modernization Act (220 ILCS 5/16-108.5(d)(1) (Act) (West 2012)). Petitioners contend
    1
    This matter was recently assigned to Justice Mason.
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    that the Commission erred in not requiring that the interest calculation be net of
    Accumulated Deferred Income Taxes (ADIT) attributable to the under-collected
    revenues. Finding no error in the Commission's order, we affirm.
    ¶2                                      BACKGROUND
    ¶3                       A. Energy Infrastructure Modernization Act
    ¶4           In Commonwealth Edison Co. v. Illinois Commerce Comm'n, 
    2014 IL App (1st) 130302
    , we recently addressed the history and purpose of the Act:
    "In 2011, the legislature enacted the Energy Infrastructure Modernization
    Act, which is section 16-108.5 of the Public Utilities Act (220 ILCS 5/16-108.5
    (West 2012)), to stimulate new investments by utilities in the State's energy
    infrastructure. The Act provides for guaranteed payment of utilities' costs and a
    rate of return for its investments in infrastructure. 'A public utility is entitled both
    to recover in its rates certain operating costs and to earn a return on its rate base
    (i.e., the amount of its invested capital).' [Citation.]
    In exchange for this legislative guarantee of payment, the utility must
    commit to making very substantial investments in updating and improving its
    facilities, and in hiring new employees. 220 ILCS 5/16-108.5(b) (West 2012). A
    public utility's participation in the Act is voluntary. 220 ILCS 5/16-108.5(b)
    (West 2012). ComEd is a participating utility and committed to invest an
    estimated $2.6 billion in infrastructure on top of its normal annual capital
    investment program over the next ten years. 220 ILCS 5/16-108.5(b)(2) (West
    2012). Under the Act the formula to establish rates enables ComEd to make
    planned substantial investment increases in its capital commitment by providing it
    -2-
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    with greater certainty of timely cost recovery than it would have received under
    previous [ratemaking procedures]." 
    Id. ¶¶ 4-5.
    ¶5           The "performance-based" formula rate is designed to operate in a standardized
    manner and is "updated annually with transparent information that reflects the utility's
    actual costs to be recovered during the applicable rate year." 220 ILCS 5/16-108.5(c)
    (West 2012).    The Act generally requires that the formula rate approved by the
    Commission "[p]rovide for the recovery of the utility's actual costs of delivery services
    that are prudently incurred and reasonable in amount consistent with Commission
    practice and law." 220 ILCS 5/16-108.5(c)(1) (West 2012). In order to place the issue
    raised here in context, we describe the ratemaking process envisioned by the Act.
    ¶6           Public utilities like ComEd are subject to both federal and state regulation. The
    Commission sets rates for power distributed in Illinois, while the Federal Energy
    Regulatory Commission (FERC) regulates interstate transmission of energy. See 220
    ILCS 5/16-101A(d) (West 2012); 16 U.S.C. § 824(a), (b)(1) (2012). Under federal law,
    ComEd is required to file annually a FERC Form 1, which sets out comprehensive
    financial and operating data for the previous year. Commonwealth Edison, 2014 IL App
    (1st) 130302, ¶ 15. Under the Act, the Commission sets rates for any given rate year on a
    preliminary basis using cost data for the prior year reflected in ComEd's most recently
    filed FERC Form 1, plus projected plant additions and updated depreciation and expense
    corresponding to those expected additions, resulting in ComEd's anticipated reasonable
    and prudent costs of service during the upcoming rate year. 220 ILCS 5/16-108.5(c)
    (West 2012). Following the calendar year for which rates were projected and once actual
    figures for that rate year are known, the Act contemplates that ComEd will compare its
    -3-
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    anticipated and actual revenue requirement and calculate the difference, which, if the
    projection underestimated actual costs of service, ComEd will recover from ratepayers or,
    if the projection exceeded actual costs of service, ComEd will refund to its customers.
    220 ILCS 5/16-108.5(d)(1) (West 2012).          We refer to the difference—positive or
    negative—as the reconciliation balance.
    ¶7           Thus, for example, ComEd's 2014 projected rate requirement was based, in part,
    on cost data from its 2013 FERC Form 1. In 2015, once ComEd's actual costs of service
    for 2014 were known, ComEd calculated the reconciliation balance and will either collect
    or refund that amount in 2016. This process repeats each year.
    ¶8           The Act recites the purpose of the reconciliation:
    "Notwithstanding anything that may be to the contrary, the intent of the
    reconciliation is to ultimately reconcile the revenue requirement reflected in rates
    for each calendar year *** with what the revenue requirement would have been
    had the actual cost information for the applicable calendar year been available at
    the filing date." 
    Id. ¶9 At
    the time of the rate proceedings at issue here, subsection 16-108.5(d)(1)
    provided:
    "Any over-collection or under-collection indicated by such reconciliation shall be
    reflected as a credit against, or recovered as an additional charge to, respectively,
    with interest, the charges for the applicable rate year." 
    Id. This provision
    was amended in 2013 to specify that interest should be "calculated at a
    rate equal to the utility's weighted average cost of capital approved by the Commission
    for the prior rate year." 220 ILCS 5/16-108.5(d)(1) (West Supp. 2013). We discuss
    -4-
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    below the circumstances and significance of this amendment.
    ¶ 10           The issue here focuses on whether interest should be calculated on the entire
    reconciliation balance or whether ADIT should be deducted from the balance prior to the
    calculation of interest. ADIT reflects the temporary timing difference between when an
    expense (or revenue) item is recognized on the company's books versus when the
    company recognizes that expense (or revenue) on its tax return. As we observed in
    Ameren Illinois Co. v. Illinois Commerce Comm'n, 
    2013 IL App (4th) 121008
    , ¶ 34,
    ADIT "quantifies the income taxes that are deferred when the tax law provides for
    deductions with respect to an item in a year other than the year that the item is treated as
    an expense for financial reporting purposes." (Internal quotation marks omitted.) As
    applied here, the timing difference means that although ComEd can recognize or "book"
    the reconciliation balance (and the associated ADIT liability) in 2015 because, due to the
    Act's provisions, it is probable that ComEd will realize that revenue in 2016, ComEd's
    obligation to pay income tax on that revenue is postponed until it is actually received in
    2016.
    ¶ 11           Finally, the Act imposes limits on ComEd's calculated return on equity. To the
    extent that collecting or refunding the reconciliation balance produces a higher or lower
    rate of return than the limits specified in the Act, the rate of return is adjusted to keep the
    prior rate year's actual return within statutory limits. 220 ILCS 5/16-108.5(c)(5) (West
    2012). These limits are commonly referred to as the Return on Equity (ROE) Collar.
    ¶ 12                                   B. Procedural History
    ¶ 13           Following the 2013 amendments to the Act, on May 13, 2013, ComEd filed
    proposed tariff pages and revised revenue requirements to implement the amendments.
    -5-
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    On June 5, 2013, the Commission approved ComEd's revised revenue requirements after
    finding that the proposed tariff changes complied with the amendments.
    ¶ 14          On September 4, 2013, the People filed a complaint with the Commission alleging
    that certain changes approved by the Commission produced excessive, unjust,
    unreasonable and unlawful rates in violation of the Act. Ultimately, the Commission
    initiated its own investigation into the matter and identified three issues to be addressed:
    whether ComEd's May 30 tariff filing correctly calculated (1) interest on the
    reconciliation balance by "grossing up" the weighted average cost of capital to account
    for the income tax effect of the portion of interest attributable to equity financing (2) the
    ROE Collar and (3) interest on the full reconciliation balance as opposed to the
    reconciliation balance net of ADIT. The order initiating the investigation designated
    ComEd as the respondent. In addition to the People and CUB, the City of Chicago and
    the Illinois Industrial Energy Consumers appeared or intervened as parties.
    ¶ 15          After discovery and exchange of information, the Commission conducted an
    evidentiary hearing on October 24, 2013. Written testimony of various experts and
    exhibits were admitted into evidence. We further discuss below the substance of the
    expert testimony. Following the hearing, the parties submitted briefs.
    ¶ 16          As relevant to the issue on appeal, petitioners argued that ComEd realized a cash
    benefit from its deferred obligation to pay income tax on the reconciliation balance and
    that allowing ComEd to calculate interest on the full reconciliation balance, without
    deducting ADIT, allowed the recovery of excessive rates.           ComEd challenged this
    assertion contending that to the extent in any given rate year, the revenues it received
    were less than its actual revenue requirement, it incurred a carrying cost for the entire
    -6-
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    shortfall and that netting ADIT from the interest calculation on the reconciliation balance
    would under compensate ComEd for this expense.
    ¶ 17          On November 13, 2013, the administrative law judge (ALJ) issued a proposed
    order for the Commission's review. After considering exceptions to the ALJ's proposed
    findings, the Commission entered its order on November 26, 2013.
    ¶ 18          As it relates to this appeal, the Commission found that the interest provision in
    subsection (d)(1) of the Act was ambiguous given that it did not specify one way or the
    other whether interest should be calculated on the entire reconciliation balance or on the
    net balance after deduction of ADIT. Resorting to principles of statutory construction,
    the Commission concluded that ComEd was entitled to calculate interest on the full
    reconciliation balance utilizing a rate equal to ComEd's weighted average cost of capital
    for the prior year. The Commission first reasoned that because the legislature had
    specified in one section of the Act that certain calculations be made on a "net" basis and
    had also referred in another provision to a calculation "adjusted for taxes," an
    interpretation that required ADIT to be deducted from the reconciliation balance prior to
    the calculation of interest under subsection (d)(1) would read into the Act "exceptions,
    limitations, or conditions the legislature did not express." The Commission also noted
    that issues regarding subsection (d)(1)'s clarity, including the method of computing
    interest on reconciliation balances, had been raised in a prior proceeding. Although the
    legislature later amended the subsection to legislatively overrule the result reached by the
    Commission on another issue, it did not change or clarify the method of computing
    interest on the reconciliation balance. Given that the legislature had an opportunity to
    clarify the issue, the Commission viewed its failure to do so as supporting the
    -7-
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    interpretation the Commission adopted here. The Commission concluded its findings on
    this issue with the observation that if, "[i]n the future, [ ] further arguments from the
    parties are presented or clarity from the legislature is provided on this topic, the
    Commission will revisit the issue."
    ¶ 19          The Commission further ruled against ComEd on the first issue of whether the
    weighted average cost of capital rate used to calculate interest on the reconciliation
    balance was appropriately "grossed up" for the income tax effect of that portion of the
    rate attributable to equity financing. The Commission found, as it did in connection with
    the ADIT issue, that the legislature had specified a rate of return in the Act and that
    ComEd's position would impose conditions on that calculation not expressed in the Act.
    Finally, the Commission rejected petitioners' proposal that an average rate base, as
    opposed to a year-end rate base, be used for purposes of calculating the ROE Collar.
    ¶ 20          The People, CUB and ComEd each sought rehearing before the Commission.
    Those applications were denied on January 15, 2014. The People, CUB and ComEd then
    timely initiated this action for administrative review pursuant to Illinois Supreme Court
    Rule 335 (eff. Feb. 1, 1994) and section 10-201 of the Public Utilities Act (220 ILCS
    5/10-201 (West 2012)). The parties' respective appeals were consolidated. On June 9,
    2014, ComEd voluntarily dismissed its appeal (No. 1-14-0114), leaving the appeals filed
    by the People (No. 1-14-0275) and CUB (No. 1-14-0403), both of which concern only
    the third issue addressed by the Commission.
    ¶ 21                                         ANALYSIS
    ¶ 22          The scope of review of a Commission order is set out in section 10-201 of the
    Public Utilities Act. 
    Id. Under this
    provision, Commission orders are deemed prima
    -8-
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    facie reasonable and the burden is on the party appealing the order to overcome that
    presumption. 220 ILCS 5/10-201(d) (West 2012); People ex rel. Madigan v. Illinois
    Commerce Comm'n, 
    2011 IL App (1st) 101776
    , ¶ 6 (quoting Commonwealth Edison Co.
    v. Illinois Commerce Comm'n, 
    398 Ill. App. 3d 510
    , 514 (2009)). Commission orders are
    subject to reversal when the Commission's findings are not supported by substantial
    evidence. 220 ILCS 5/10-201(e)(iv)(A) (West 2012). Notwithstanding the statute's
    reference to "substantial evidence," our supreme court has held that the Commission's
    factual findings must be upheld unless they are contrary to the manifest weight of the
    evidence. People ex rel. Hartigan v. Illinois Commerce Comm'n, 
    148 Ill. 2d 348
    , 367
    (1992); see also Commonwealth Edison Co. v. Illinois Commerce Comm'n, 2014 IL App
    (1st) 122860, ¶ 58 (applying manifest weight standard). Findings of fact are deemed
    contrary to the manifest weight of the evidence only when an opposite conclusion is
    clearly evident from the record. Continental Mobile Telephone Co. v. Illinois Commerce
    Comm'n, 
    269 Ill. App. 3d 161
    , 171 (1994). As the parties challenging the Commission's
    order, petitioners must affirmatively demonstrate that the conclusion opposite to that
    adopted by the Commission is clearly evident. 
    Id. ¶ 23
             We accord deference to decisions of the Commission in light of its expertise and
    experience in the complex field of utility regulation. Archer-Daniels-Midland Co. v.
    Illinois Commerce Comm'n, 
    184 Ill. 2d 391
    , 397 (1998); Commonwealth Edison Co. v.
    Illinois Commerce Comm'n, 
    398 Ill. App. 3d 510
    , 514 (2009). Where the Commission's
    decision involves construction of a statute, the extent of that deference depends on
    whether the statute is ambiguous.
    -9-
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    ¶ 24           When the Commission construes an unambiguous statute, the agency's
    interpretation is not binding on the court (People ex rel. Madigan, 
    2011 IL App (1st) 101776
    , ¶ 6) and the court need not defer to the agency's interpretation. But although
    agency interpretations of ambiguous statutory provisions are likewise not binding, we
    give "substantial weight and deference to an interpretation of an ambiguous statute by the
    agency charged with the administration and enforcement of the statute."             (Internal
    quotation marks omitted.) 
    Id. This is
    particularly true when the interpretation draws on
    the agency's expertise and experience and we will not substitute our own construction of
    an ambiguous statute for a reasonable interpretation adopted by the agency charged with
    its administration. Quality Saw & Seal, Inc. v. Illinois Commerce Comm'n, 
    374 Ill. App. 3d
    776, 781 (2007) ("if reasonable readers of a statute could differ over the extent of the
    regulatory authority it confers, we defer to the agency's interpretation if the interpretation
    is defensible").
    ¶ 25           As in any other case involving the construction of a statute, our review is de novo.
    Ameren, 
    2013 IL App (4th) 121008
    , ¶ 18.               We will not reverse a Commission
    interpretation of law unless it is erroneous.        Illinois Bell Telephone Co. v. Illinois
    Commerce Comm'n, 
    282 Ill. App. 3d 672
    , 676 (1996).
    ¶ 26           Although ComEd argues that subsection (d)(1) is not ambiguous, we conclude the
    Commission correctly determined that the provision was open to more than one
    reasonable interpretation and was thus ambiguous.             As the Commission noted, this
    provision fails to address the method of computing interest on the reconciliation balance
    and so it is only by resort to interpretative aids other than the language of the provision
    itself that the intent of the legislature can be discerned.
    - 10 -
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    ¶ 27          Normally, the language of a statute is the best indicator of its meaning. Solon v.
    Midwest Medical Records Ass'n, 
    236 Ill. 2d 433
    , 440 (2010) (citing Blum v. Koster, 
    235 Ill. 2d 21
    , 29 (2009)). But when statutory language is ambiguous and susceptible to more
    than one interpretation, both of which are reasonable, it is appropriate to resort to other
    aids to construction to determine legislative intent. 
    Id. (citing Landis
    v. Marc Realty,
    L.L.C., 
    235 Ill. 2d 1
    , 11 (2009)).
    ¶ 28          The Commission further found, and we agree, that there is support for both
    interpretations advocated by the parties. 2 Experts for petitioners opined that allowing
    interest to be calculated on the full reconciliation balance fails to take into account the
    cash benefit realized by ComEd as a result of its delayed obligation to pay income tax on
    the revenue shortfall. Because, during the current rate year, ComEd records revenue
    expected to be received in the following year, it likewise records a deferred income tax
    expense related to that revenue. According to petitioners' experts, the net impact is that
    ComEd records higher earnings due to the reconciliation revenue, but delays payment of
    the income tax associated with those higher earnings until the revenue is actually
    received from customers, a result they assert provides a cash benefit to the utility.
    Consequently, they reason that the out-of-pocket cost to ComEd as a result of the
    reconciliation balance is the after-tax amount of the balance and that interest should be
    calculated only on that amount.
    ¶ 29          Petitioners' experts further observed that netting ADIT from interest calculations
    was consistent with generally accepted accounting principles (GAAP) and standard
    2
    Indeed, before the Commission, CUB took the position that because subsection
    (d)(1) did not specifically address the issue, the proper interpretation was up to the
    Commission.
    - 11 -
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    regulatory practice that matches ADIT to the associated assets included in rate base, thus
    recognizing the cash benefit to the utility of the accounting treatment.
    ¶ 30           ComEd counters that petitioners' experts failed to take into account the carrying
    costs incurred by the utility on the revenue shortfall, which ComEd must finance for two
    years prior to its recovery. Thus, although ComEd is able to defer payment of income tax
    associated with the reconciliation balance, it must finance the entire shortfall, including
    the deferred tax amount, and a formula rate that computes interest only on the balance net
    of ADIT would not allow ComEd to recover the full cost associated with the
    reconciliation balance.
    ¶ 31           ComEd's expert, Christine Brinkman, further articulated why ADIT in the context
    of rate base and ADIT in the context of a reconciliation balance are different. ADIT is
    deducted from rate base (comprised of investor funds on which the utility is allowed to
    earn a return) to recognize the cash benefit realized from the excess of tax over book
    depreciation. Brinkman explained that assets may, for book purposes, depreciate over 30
    years, but for income tax purposes, those same assets depreciate over 5 years. Given the
    larger depreciation deduction for tax purposes, ComEd's taxes payable are reduced in the
    current rate year, resulting in cash available (from ratepayers) to fund rate base
    investments. In contrast, the reconciliation balance provides no cash to ComEd until it is
    collected. Thus, in this context, ADIT provides no benefit to the utility in the current rate
    year and the entirety of the shortfall must be financed by ComEd through investor
    supplied funds until it is collected.

    ¶ 32          A simple hypothetical illustrates the difference in outcomes. If we assume an
    under-collection of revenues of $100,000, a 10% interest rate and an effective tax rate of
    40%, the two approaches produce the following results:
    Calculation of Interest before ADIT              Calculation of Interest after ADIT
    Undercollection:               $100,000          Undercollection:             $100,000
    Plus Interest at 10%:           +10,000          Less ADIT:                   - 40,000
    Less ADIT on balance:           - 44,000         Plus Interest at 10%:        + 6,000
    Tax on Balance ($106,000):      42,000
    Net of tax recovery:            $ 66,000         Net of tax recovery:          $ 64,000
    Hypothesizing an over recovery of revenues in the same amount, requiring a refund of
    the reconciliation balance plus interest to ratepayers, produces the same result, i.e.,
    calculating interest without netting ADIT results in a greater net of tax recovery to
    ComEd's customers.
    ¶ 33          As noted, the Commission did not expressly address the question from an
    accounting standpoint or determine, as a factual matter, whether ComEd realized a cash
    benefit from ADIT on the reconciliation balance. Rather, the Commission determined
    legislative intent regarding the alternative approaches by examining other provisions of
    the Act as well as legislative action following a previous rate proceeding, which involved
    the application of subsection (d)(1). Both of these approaches are acceptable aids to
    statutory construction in the case of an ambiguous statute. See State Bank of Cherry v.
    CGB Enterprises, Inc., 
    2013 IL 113836
    , ¶ 56 (" '[w]hen the legislature uses certain
    language in one part of a statute and different language in another, we may assume
    different meanings were intended' " (quoting People v. Hudson, 
    228 Ill. 2d 181
    , 193

    Nos. 1-14-0275 & 1-14-0403 (cons.)

    language of ambiguous statute in isolation, but will consider other relevant provisions of
    the statute (citing People v. Beachem,

    O'Neill, 
    138 Ill. 2d 487

    , 483
    (1983))); Stevens v. Lou's Lemon Tree, Ltd., 
    187 Ill. App. 3d 458
    , 464 (1989)
    ("Amendments to a statute *** are assumed to be enacted with the legislature's
    knowledge of judicial construction of the law."). We cannot say that the Commission's
    approach was unreasonable or that the resulting interpretation was erroneous.
    ¶ 34          The Commission first identified other provisions of the Act in which the
    legislature specifically directed adjustments to an amount or a balance. Specifically,
    section 108.5(c) of the Act (220 ILCS 5/16-108.5(c) (West 2012)) directs that amounts
    related to projected plant additions are included in rate base on a net basis considering
    "updated depreciation reserve and expense." Also, the Act's formula for the ROE Collar
    calculation in section 108.5(c)(5) expressly requires that the calculation be "adjusted for
    taxes." 220 ILCS 5/16-108.5(c)(5) (West 2012). The Commission reasoned that because
    in other provisions of the Act, the legislature imposed "exceptions, limitations or
    conditions" on required calculations, its failure to likewise condition or otherwise limit
    the calculation of interest on the reconciliation balance meant that the entire balance
    should bear interest, not the "net" balance or the balance "adjusted for" ADIT.
    ¶ 35          Although petitioners fault the Commission's reasoning on this point, we find it
    persuasive. The legislature easily could have defined the manner in which "interest"
    - 14 -
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    should be calculated on the "balance," but unlike other provisions of the Act, chose not
    to. We view this as a reliable indicator that no further limitations were intended. See
    Davis v. Toshiba Machine Co., America, 
    186 Ill. 2d 181
    , 186 (1999) (had legislature
    intended to restrict application of statute of repose in product liability cases to latent
    injuries, "it would have inserted that limitation").
    ¶ 36           The Commission also found it significant that the legislature failed to amend the
    language regarding the interest calculation following the Commission's decision in a prior
    proceeding before the Commission to consider the Act's interest provision. In ICC
    Docket No. 11-0721, the first proceeding following the Act's effective date, the
    Commission addressed issues regarding the rate to be used in calculating interest on the
    reconciliation balance under subsection (d)(1). Commonwealth Edison Co., Ill. Com.
    Comm'n No. 11-0721, at 33-36 (Order on Rehearing Oct. 3, 2012). Specifically, ComEd
    contended that the rate should be equal to its weighted average cost of capital.
    Commission staff advocated utilizing a rate equal to an AAA-rated bond for two years
    (the period of time during which the balance—positive or negative—is carried by
    ComEd). The Commission ultimately adopted a hybrid approach that calculated the rate
    taking into account ComEd's cost of capital, the nature of the obligation and the
    applicable borrowing period, resulting in a lower rate than ComEd's weighted average
    cost of capital.
    ¶ 37           In the course of the prior proceedings, although it did not resolve the issue, the
    Commission also addressed the People's contention—identical to the argument advanced
    here—that interest should be calculated on the reconciliation balance after the deduction
    of ADIT to assure that consumers receive the benefit of income tax deferrals. ComEd
    - 15 -
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    contended that the deferred income tax liability provided no source of cash to offset the
    revenue shortfall. The Commission "declined to adopt" the People's position, stating:
    "ComEd contends that this recommendation does not provide ComEd with
    cash.   [The People] provide little information establishing that this
    procedure is within generally accepted accounting procedures or that it
    would of benefit to ComEd or to ratepayers." Commonwealth Edison Co.,
    Ill. Com. Comm'n No. 11-0721, at 167 (Final Order, May 29, 2012).
    ¶ 38          As noted above, following the Commission's decision, the legislature amended
    subsection (d)(1) to overrule the Commission's determination as to the appropriate rate of
    interest, specifically directing that the rate to be used in calculating interest on the
    reconciliation balance is the utility's weighted average cost of capital. At the same time,
    although the legislature was undoubtedly aware of the People's contention that the same
    subsection should be interpreted to require the deduction of ADIT prior to the calculation
    of interest, the legislature neither adopted that position via amendment nor did it
    otherwise clarify subsection (d)(1).
    ¶ 39          Petitioners discount the significance of the legislature's failure to further define
    the "balance" on which interest is calculated. They argue that since the Commission did
    not actually decide the issue in the prior proceedings, but rather declined to address it for
    lack of evidence, the legislature's inaction should not be interpreted as approving
    ComEd's position. While we agree that the Commission's act in declining to adopt the
    People's position for lack of evidence is not the functional equivalent of a decision on the
    merits, the salient point is that when it amended subsection (d)(1), the legislature would
    have been aware of the dispute. Since it was amending this very subsection, it would
    - 16 -
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    have been logical, therefore, to clarify the issue if, in fact, the legislature agreed that
    interest should be calculated on the "net" reconciliation balance or the balance "adjusted
    for taxes." Consequently, we believe the Commission's properly found the legislature's
    failure to act to be indicative of the legislature's view that the "balance, with interest"
    means the whole balance and not some derivative thereof.
    ¶ 40             Petitioners contend that the Commission acknowledged that petitioners' position
    on this issue had "merit" in that it was consistent with GAAP and standard regulatory
    practice, but declined to adopt it because the Commission believed it lacked authority to
    do so. We disagree, as does the Commission, with this explanation for the Commission's
    ruling.
    ¶ 41             First, the Commission points out, it has not been "standard regulatory practice" to
    deduct ADIT from reconciliation balances for purposes of calculating interest. While
    longstanding practice has been to deduct ADIT from rate base, there is no similar history
    with respect to reconciliation balances given the Act's recent vintage. And we find
    persuasive Brinkman's explanation of the difference that context makes in assessing
    whether ADIT results in a cash benefit to the utility given that, in the reconciliation
    balance context, both the revenue and the corresponding tax liability will be received and
    paid, respectively, in the future.      Thus, petitioner's emphasis on the Commission's
    reference to standard regulatory practice is misplaced.
    ¶ 42             For the same reason, Ameren, 
    2013 IL App (4th) 121008
    , is inapposite. Ameren
    dealt with the "standard regulatory practice" of deducting ADIT from rate base, a concept
    with which ComEd does not disagree. Because, as explained above, ADIT resulting from
    the difference between book and tax depreciation provides a source of cash to the utility,
    - 17 -
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    Ameren determined that failing to net ADIT from rate base would "allow [the utility]
    what amounts to an interest -free loan at ratepayers' expense." 
    Id. ¶ 39.
    Here, in contrast,
    ComEd presented credible arguments that ADIT associated with a reconciliation balance
    provides no cash benefit to a utility given that the revenues associated with the deferred
    tax liability will not be realized until future rate years. Thus, unlike ADIT in the context
    of rate base, ADIT associated with a reconciliation balance does not reduce the utility's
    current tax liability nor does it afford the utility a source of funds at its customers'
    expense.
    ¶ 43          Further, while GAAP dictates the methodology for recording revenue and
    expense items for accounting purposes, it does not purport to predict whether the
    accounting treatment results in a "cash benefit" to the business, which was the focus of
    the parties' arguments before the Commission.         For this reason, the Commission's
    comment that the "concept" of netting ADIT against the reconciliation balance is
    consistent with GAAP is not the same as a finding that ADIT must be deducted under the
    language of the statute or that the failure to deduct ADIT prior to calculating interest on
    the balance is inconsistent with GAAP.
    ¶ 44          Petitioners contend that the tentative nature of the Commission's ruling evidenced
    by its stated willingness to revisit the issue should circumstances warrant indicates that
    the Commission is intimidated by recent legislative overrides of its rulings and has thus
    abdicated its statutory directive to establish rates, "which it shall find to be just and
    reasonable."   220 ILCS 5/9-201(c) (West 2012).            We disagree.     We view the
    Commission's statement in this regard as an acknowledgement that this is the first
    definitive resolution of this issue. As noted, although the People raised this issue in a
    - 18 -
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    prior proceeding, the Commission did not address the issue on its merits, instead
    declining to adopt the People's position for lack of supporting evidence.               The
    Commission has now considered additional evidence and arguments advanced by all
    parties and has reaffirmed its prior decision not to adopt the People's proposal. We view
    the Commission's further statement of its willingness to consider this issue in future
    proceedings as nothing more than a recognition that the legislature may opt to consider
    further amendments to the Act.
    ¶ 45          As the Commission notes, its observation that there "may be merit" to petitioners'
    proposal is not an indication that ComEd's position lacks merit or that the Commission
    believes petitioners' interpretation of subsection (d)(1) is the correct one. Indeed, for the
    reasons we have articulated above, the Commission found, we believe correctly, that the
    interpretation advocated by ComEd was consistent with legislative intent.              Once
    legislative intent is determined, the Commission is not free to make findings inconsistent
    with that intent, even if the Commission might have ruled otherwise had the matter been
    committed to its discretion.     See Illinois Bell Telephone Co. v. Illinois Commerce
    Comm'n, 
    283 Ill. App. 3d 188
    , 207 (1996) ("It is impermissible for the Commission to
    substitute its reasonableness standard for the legislature's absolute standard."). Certainly
    petitioners have not sustained their burden to identify anything in the language of
    subsection (d)(1) or its legislative history that compels a finding that ADIT must be
    deducted from a reconciliation balance prior to the calculation of interest. Thus, we
    cannot say that the conclusion opposite to the one reached by the Commission is "clearly
    evident." Continental Mobile Telephone 
    Co., 269 Ill. App. 3d at 171
    .
    - 19 -
    Nos. 1-14-0275 & 1-14-0403 (cons.)
    ¶ 46            Finally, contrary to petitioners' contention, nothing in the record before the
    Commission leads us to conclude that the adoption of ComEd's position results in the
    recovery of unjust or unreasonable rates. Fundamentally, this argument overlooks the
    fact that the benefit flowing from the higher interest calculation inures to the utility in
    some years and ratepayers in others.       Specifically, in years where ComEd recovers
    revenues in excess of its actual revenue needs and must refund the excess to its
    customers, the method of calculating interest on the reconciliation balance adopted by the
    Commission results in a higher refund to ratepayers. Under these circumstances, it
    cannot be said that the interest rate calculation approved by the Commission produces
    rates that unjust and unreasonable.
    ¶ 47                                     CONCLUSION
    ¶ 48            The Commission had the power to interpret the provisions of the Act relating to
    the calculation of interest on the reconciliation balance, which it exercised in accordance
    with well-established principles of statutory construction. Nothing in the Act or its
    legislative history compels the finding that the only possible interpretation of the interest
    provision is that advocated by petitioners and we therefore we affirm the Commission's
    order.
    ¶ 49            Affirmed.
