OPINION

CHEN, District Judge:

I. INTRODUCTION

This bankruptcy appeal concerns confirmation of a Chapter 13 plan of reorganization. The debtors, Cesar and Ana Flores, proposed a three-year plan. Rod Danielson, the Chapter 13 Trustee ("Trustee"), objected and argued that a five-year plan was required. The relevant legal question is whether, under 11 U.S.C. § 1325(b), a debtor with no "projected disposable income" may confirm a plan that is shorter in duration than the "applicable commitment period" found in § 1325(b).

Current Ninth Circuit precedent plainly allows debtors to confirm a shorter plan (e.g., a three-year plan) under the facts of this case. See Maney v. Kagenveama (In re Kagenveama), 541 F.3d 868, 872 (9th Cir.2008). However, Trustee argued, and the bankruptcy judge agreed, that the Supreme Court's intervening decision in Hamilton v. Lanning, ___ U.S. ___, 130 S.Ct. 2464, 177 L.Ed.2d 23 (2010), is irreconcilable with and thus implicitly overruled Kagenveama's construction of "applicable commitment period," which permits shorter Chapter 13 plans. The question before this court is whether the bankruptcy judge erred when it declined to follow this court's otherwise controlling holding in Kagenveama because the bankruptcy judge deemed Kagenveama irreconcilable with Lanning. We disagree and hold that Lanning is not clearly irreconcilable with Kagenveama's construction of "applicable commitment period." Accordingly, we reverse and remand to the bankruptcy court for further proceedings consistent with this opinion.

II. FACTUAL AND PROCEDURAL BACKGROUND

Cesar and Ana Flores ("Debtors") filed a petition for relief under Chapter 13 of the Bankruptcy Code. Debtors proposed a plan of reorganization with a duration of 36 months, calling for a monthly payment of $122. Trustee objected to the plan, arguing that the Bankruptcy Code requires a minimum plan duration of 60 months and that Ninth Circuit precedent to the contrary had been implicitly overruled by an intervening Supreme Court decision. The Bankruptcy Court sustained the objection and confirmed a 60-month plan calling for a monthly payment of $148.1

Debtors timely appealed to the Bankruptcy Appellate Panel ("BAP"). The bankruptcy court then certified the plan duration issue for direct appeal to this court, pursuant to 28 U.S.C. § 158(d)(2).2

The relevant facts are not disputed: Debtors' "current monthly income," as that term is defined in the Bankruptcy Code, is above the median income for their locality. Debtors' monthly "disposable income," as that term is defined in the Bankruptcy Code, is negative. Debtors have unsecured debts. Debtors' proposed plan would pay 1% of allowed, unsecured, non-priority claims.

III. STANDARD OF REVIEW

Questions of "statutory interpretation and Ninth Circuit precedent" are questions of law, which this court reviews de novo. Lyon v. Chase Bank USA, N.A., 656 F.3d 877, 883 (9th Cir.2011); see also Baker v. Delta Air Lines, Inc., 6 F.3d 632, 637 (9th Cir.1993) ("Whether stare decisis applies ... [is an] issue[] of law, reviewable de novo.").

IV. DISCUSSION

We begin with a review of the statutory framework at issue in this case, as well as a discussion of this court's prior ruling in Kagenveama and the Supreme Court's intervening decision in Lanning.

A. Statutory Framework

The Bankruptcy Code imposes a number of conditions on confirmability of a plan of reorganization under Chapter 13. Among those conditions is the requirement that debtors pay any "projected disposable income" to unsecured creditors. See 11 U.S.C. § 1325(b)(1)(B). The statute establishing such a requirement reads in relevant part as follows:

Id. § 1325(b)(1) (emphasis added). Thus, for a given debtor, this subsection involves two threshold determinations: (1) the debtor's "projected disposable income," and (2) the debtor's "applicable commitment period."

In order to apply the above requirements, a court must first classify the debtor as either "above-median" or "belowmedian." See, e.g., In re Mattson, 456 B.R. 75, 82 (Bankr.W.D.Wash.2011) (using the quoted terminology for the purposes of determining the "applicable commitment period"); In re Diaz, 459 B.R. 86, 91 & n. 6 (Bankr.C.D.Cal.2011) (using the quoted terminology for the purposes of "projected disposable income"). As discussed in more detail below, the calculation of "disposable income" depends on whether a debtor has above-median or below-median income. § 1325(b)(3).3 The "applicable commitment periods" in which a debtor must pay her "projected disposable income" also differ for above-median versus below-median debtors. § 1325(b)(4). In this case, Debtors are above-median. We therefore focus on the requirements for above-median debtors.

1. Disposable Income and Projected Disposable Income

"The [Bankruptcy] Code [does] not define the term `projected disposable income....'" Lanning, 130 S.Ct. at 2469. However, the Code does define "disposable income." Section 1325(b)(2) provides, in relevant part:

(Emphases added.) For an above-median debtor such as the Debtors in this case, § 1325(b)(3) provides:

Section 707(b)(2), in turn, sets forth a "formula... known as the `means test' and is reflected in a schedule (Form 22C) that a Chapter 13 debtor must file." Lanning, 130 S.Ct. at 2470 n. 2. Thus, the statute prescribes a formula to calculate an above-median debtor's disposable income. From that formula, a debtor's "projected disposable income" is then projected into the future to determine what monthly payment the debtor owes to unsecured creditors. § 1325(b)(1)(B). As we discuss infra, the exact method by which one calculates "projected disposable income" — a term undefined in the statute — from "disposable income" has been a topic of vigorous debate among courts until the Supreme Court's recent decision in Lanning.

Because the "means test" imposed by the Bankruptcy Abuse Prevention and Consumer Protection Act ("BAPCPA") of 2005, Pub.L. No. 109-8, 119 Stat. 23, calculates expenses using formulaic categories keyed to local data rather than the actual expenses of an individual debtor, sometimes, as in this case, an above-median debtor who is capable of pledging a monthly sum to repayment for the benefit of creditors has negative disposable income. See 8 Collier on Bankruptcy ¶ 1325.11[4][c][I] (Alan N. Resnick & Henry J. Sommer eds., 16th ed.2010); cf. In re Alexander, 344 B.R. 742, 750 (Bankr. E.D.N.C.2006) ("Because the pre-BAPCPA definition of `disposable income' calculated a real number rather than a statutory artifact, ... a debtor with no positive number simply had no means to fund the added costs of a Chapter 13 plan."). Negative disposable income under BAPCPA can in turn result in a negative "projected disposable income," under the statute. In the instant case, it is undisputed that Debtors have negative projected disposable income.

2. Applicable Commitment Period

Unlike "projected disposable income," for which the meaning must be deduced from "disposable income," the Bankruptcy Code provides a precise definition for "applicable commitment period." Section 1325(b)(4) provides in relevant part:

(Emphasis added.)

Because the Debtors will not make payment in full to unsecured creditors and they are above-median, "the applicable commitment period" under § 1325(b)(4) is five years. While the applicable commitment period is clear, its role in defining the duration of the Debtor plan of reorganization is not.

B. Pre-Lanning Interpretations of 11 U.S.C. § 1325(b)

Prior to the Supreme Court's decision in Lanning, courts diverged in their interpretation of the elements of § 1325. We summarize these disagreements below by way of background to this Circuit's law and Lanning's potential impact on this case.

1. Projected Disposable Income

First, pre-Lanning, courts differed as to how they interpreted the undefined term "projected disposable income" in relation to the defined term "disposable income." Two competing interpretations have been termed the "mechanical" approach and the "forward-looking" approach. See Lanning, 130 S.Ct. at 2471; Kagenveama, 541 F.3d at 871-72; Nowlin v. Peake (In re Nowlin), 576 F.3d 258, 262-63 (5th Cir. 2009).

Under the mechanical approach, "`projected disposable income' means `disposable income,' as defined by § 1325(b)(2), projected over the `applicable commitment period'" by means of simple, or mechanical, multiplication. Kagenveama, 541 F.3d at 871-72; see also Lanning, 130 S.Ct. at 2471. For example, if a debtor's disposable income, according to the statutory formula, is $100 per month, and if the debtor's applicable commitment period is five years (or 60 months), the debtor's total projected disposable income is $6,000.

The forward-looking approach, by contrast, uses the "disposable income" calculation only as a "starting point," Kagenveama, 541 F.3d at 872, "determinative in most cases," Lanning, 130 S.Ct. at 2471, but subject to modification upon a demonstration of "substantial changes to the debtor's income or expenses that have occurred before confirmation or will occur within the plan's period," Nowlin, 576 F.3d at 263. Thus, if the debtor's income during the six months prior to filing her bankruptcy petition — the baseline used to calculate disposable income — is somehow demonstrably different from the debtor's current or future income, such changed circumstances could factor into the "projected disposable income" calculation under the forward-looking approach. For example, a debtor who lost her job after filing the petition could have a much lower monthly "projected disposable income" than her "disposable income," which was based on her previous job's paycheck. See id. at 263-64 (describing potential changes such as "a promotion at work, the loss of a job, the acquiring of a second job, or increased medical expenses" (internal quotation mark omitted)).

As discussed further below, this debate was settled by the Supreme Court in Lanning, in favor of the forward-looking approach.

2. Applicable Commitment Period

A second debate among courts concerns whether § 1325(b)'s "applicable commitment period" sets forth a "temporal" requirement or a "monetary" requirement. The latter approach is also sometimes referred to as the "multiplier" approach. Baud v. Carroll, 634 F.3d 327, 336-37 & n. 7 (6th Cir.2011), cert. denied, ___ U.S. ___, 132 S.Ct. 997, 181 L.Ed.2d 732 (2012). Under the temporal approach, the "applicable commitment period" establishes the minimum duration of the plan.4 Id. at 336-37 (collecting cases); see, e.g., Whaley v. Tennyson (In re Tennyson), 611 F.3d 873, 877-78 (11th Cir.2010) ("The plain reading of § 1325(b)(4) indicates that an above median income debtor, such as Tennyson, is obligated to form a bankruptcy plan with an `applicable commitment period' of no less than five years, unless his unsecured debts are paid in full.").

By contrast, under the monetary approach, the "applicable commitment period" is used to define not the duration of the plan but the total sum to be paid by the debtor under the plan. It is used as a multiplier in calculating the total "projected disposable income" to be paid to unsecured creditors over the life of the plan. As the court in Baud explained, the monetary approach

634 F.3d at 337 (collecting cases adopting this approach). Once calculated, the debtor can pay that total sum over a shorter period of time. See, e.g., In re Swan, 368 B.R. 12, 26 (Bankr.N.D.Cal.2007) ("`[W]here the debtor's projected disposable income is consistent with the calculations on Form B22C, it makes little sense to hold the debtor hostage for 60 months where the debtor can satisfy the requirements of § 1325(b)(1)(B) in a shorter period.'" (quoting In re Fuger, 347 B.R. 94, 101 (Bankr.D.Utah 2006))).

Other courts, including this court in Kagenveama, have adopted a hybrid5 variation in which the "applicable commitment period" sets the minimum temporal duration of a plan, but it is "inapplicable to a plan submitted ... by a debtor with no `projected disposable income.'" Kagenveama, 541 F.3d at 875; see, e.g., Alexander, 344 B.R. at 751 ("Because applicable commitment period is a term the statute makes relevant only with regard to the required payment of projected disposable income to unsecured creditors and not to any other plan payments or requirements, it simply does not come into play where no projected disposable income must be taken into account."). See generally Baud, 634 F.3d at 337 (collecting additional cases).

In addition to the split among the lower courts, leading commentators are divided on its answer. Id. at 338 (citing 8 Collier on Bankruptcy ¶ 1325.08[4][d]; and 6 Keith M. Lundin, Chapter 13 Bankruptcy, § 500.1 (3d ed. 2000 & Supp.2006)). The proper interpretation of the meaning and function of the "applicable commitment period" has not been directly addressed by the Supreme Court.

C. Kagenveama

In 2008, this court addressed both of the questions out-lined above, deciding in favor of the mechanical approach in defining "projected disposable income" and the hybrid approach in interpreting the "applicable commitment period." Kagenveama, 541 F.3d 868.

In support of the mechanical approach to determining "projected disposable income," Kagenveama first relied on textual analysis:

Id. at 872-73. Kagenveama also relied on pre-BAPCPA practice, which it read to support the mechanical approach. Id. at 873-74 & n. 2. It rejected the forward-looking approach, stating that nothing in the Bankruptcy Code supports the reading of "disposable income" as merely a presumptive starting point, subject to modification. Id. at 874-75. Finally, the court rejected the contention that the mechanical approach led to absurd results. Id. at 875.

In adopting the hybrid approach to the "applicable commitment period," Kagenveama stated:

Id. (emphasis added). The court reasoned that any payments made by such a debtor must derive from sources other than "projected disposable income," and so the "applicable commitment period," which is tied to that term, would be irrelevant. Id. at 876. The court's analysis relied on the text of the statute, and explicitly rejected policy arguments to the contrary:

Id. at 876-77 (citations and footnote omitted) (4th ellipsis added).

The court also noted that its interpretation was not inconsistent with pre-BAPCPA practice, which similarly provided for a temporal period (in that case, a period of "three years"). However, the court found that when a debtor had no disposable (or projected disposable) income, there was no "applicable commitment period" to apply. Id. at 875-76. Such a scenario — a debtor with no projected disposable income who could nonetheless make payments to unsecured creditors — did not exist pre-BAPCPA because BAPCPA replaced a debtor's actual ability to pay (based on real numbers) with a formula for calculating disposable income. See Alexander, 344 B.R. at 750. Thus, there was no applicable pre-BAPCPA practice with respect to debtors with no disposable income, as such debtors could not propose confirmable plans prior to the Act. See id. ("[A] debtor under the new `disposable income' test may show a zero or negative number, yet may be able to make the required showing that she actually has enough income to fund a confirmable plan.").

D. The Supreme Court's Decision in Lanning

Lanning involved a debtor whose "current monthly income" — the pre-petition baseline from which one calculates "disposable income" under § 1325(b)(2) — was inflated well beyond her actual post-petition income because of a one-time aberration. 130 S.Ct. at 2470 (explaining that the debtor had received a one-time buyout from her former employer prior to filing for bankruptcy, and that these one-time payments had "greatly inflated" her disposable income). In such a scenario, applying the mechanical approach to calculating her "projected disposable income" would have resulted in monetary payments that would substantially exceed her ability to pay. Id. The Supreme Court rejected the mechanical approach and adopted the forward-looking approach, overruling the portion of Kagenveama that addressed "projected disposable income." Id. at 2469.

In so doing, the Lanning Court relied primarily on a textual analysis that distinguished "projected disposable income" from "disposable income." The Court reasoned that "the ordinary meaning of the term `projected' .... takes past events into account, [but allows] adjustments ... based on other factors that may affect the final outcome." Id. at 2471-72; see also id. at 2471 ("[I]n ordinary usage future occurrences are not `projected' based on the assumption that the past will necessarily repeat itself."). It rejected Kagenveama's argument that the forward-looking approach renders the definition of "disposable income" superfluous:

Id. at 2475. The Court also looked to the meaning of "projected" in other federal statutes, which used "projected" to mean not just "simple multiplication," but estimates adjusted for changed conditions and trends. Id. at 2472.

The Court further supported its conclusion by reference to pre-BAPCPA practices, which it evaluated differently than did the Ninth Circuit. See id. at 2472-74. Specifically, the Court noted that pre-BAPCPA courts used the mechanical approach as a starting point, but "also had discretion to account for known or virtually certain changes in the debtors' income." Id. at 2473-74. The Court concluded that "[i]n light of this historical practice," and because "Congress did not amend the term `projected disposable income' in 2005," "we would expect that, had Congress intended for `projected' to carry a specialized — and indeed, unusual — meaning in Chapter 13, Congress would have said so expressly." Id.

Finally, the Court considered the senseless consequences that could result from the mechanical approach:

Id. at 2475-76.

Lanning did not address the meaning of "applicable commitment period." Its holding only concerned the interpretation of "projected disposable income."

E. Lanning's Impact on Kagenveama and This Case

In the instant case, we confront the question of Kagenveama's continued vitality in light of Lanning. Lanning necessarily overruled the first part of Kagenveama. See In re Henderson, 455 B.R. 203, 208 (Bankr.D.Idaho 2011) ("Because the Supreme Court adopted the forward-looking approach, as opposed to the Kagenveama-favored mechanical approach, Kagenveama's instructions to bankruptcy courts for calculating debtors' projected disposable income were effectively overruled."). What remains unsettled is whether Lanning's reasoning, which did not address the "applicable commitment period" question, is clearly irreconcilable with and thus effectively overruled Kagenveama's second holding interpreting "applicable commitment period."

In Miller v. Gammie, we explained that "issues decided by the higher court need not be identical in order to be controlling. Rather, the relevant court of last resort must have undercut the theory or reasoning underlying the prior circuit precedent in such a way that the cases are clearly irreconcilable." 335 F.3d 889, 900 (9th Cir.2003) (en banc) (emphasis added).

Importantly, this inquiry does not ask how the panel would interpret the "applicable commitment period" provision if we were to consider the issue as a matter of first impression. Rather, we are bound by our prior precedent if it can be reasonably harmonized with the intervening authority. See, e.g., Avagyan v. Holder, 646 F.3d 672, 677 (9th Cir.2011) ("A three-judge panel cannot reconsider or overrule circuit precedent unless an intervening Supreme Court decision undermines an existing precedent of the Ninth Circuit, and both cases are closely on point." (internal citations and quotation marks omitted)).

In this case, we find that the Supreme Court's decision in Lanning is not "clearly irreconcilable" with Kagenveama's interpretation of "applicable commitment period." We so conclude for two reasons. First, the overall analytical framework of Lanning, which (1) employed a textual analysis of statutory language at issue, (2) reviewed pre-BAPCPA practice, and (3) examined policy consequences of a contrary interpretation, is consistent with our overall analytical approach in Kagenveama. Second, the application of Lanning's three-factor analysis in construing "projected disposable income" does not mandate any particular interpretation of the different term "applicable commitment period."

1. Analytical Framework

The overarching analytical framework employed by the Supreme Court in Lanning is similar to and consistent with the analytical framework used by this court in Kagenveama. Lanning analyzed three factors. First, Lanning employed a textual analysis to determine the meaning of "projected disposable income" used in § 1325(b)(1) as it relates to "disposable income" defined in (b)(2) and (b)(3). Second, Lanning examined pre-BAPCPA practice, adopting the pre-BAPCPA approach to determining "projected disposable income" in the absence of any indication that Congress, in enacting BAPCPA, intended to change that practice. Third, it tested for possible senseless results that could arise under alternative interpretations of "projected disposable income."

Kagenveama employed the same general framework in its interpretation of "applicable commitment period." Like Lanning, the court considered the text and structure of § 1325(b) (as well as the relationship to § 1322(d)) to determine the meaning of "applicable commitment period" as it is defined in (b)(4) and used in (b)(1). Kagenveama also briefly considered pre-BAPCPA practice as it relates to the meaning of "period," although the precise scenario the court addressed did not have a pre-BAPCPA analog. Finally, it considered possible senseless results according to the statute's purpose, and concluded that nothing in BAPCPA's text or purpose mandated a minimum term length or "applicable commitment period" for debtors who had no "projected disposable income."

2. Application of the Three-Factor Framework

In addition to the fact that both Kagenveama and Lanning employed the same general analytical framework, there is nothing in Lanning's specific application of the three-factor framework in interpreting "projected disposable income" ("PDI") that is clearly inconsistent with Kagenveama's application of that similar framework in interpreting "applicable commitment period" ("ACP").

a. Text and Structure of § 1325(b)

First, Lanning's textual analysis of "projected disposable income" is sui generis to the issue at hand therein. "Lanning [did not] directly address[] the applicable commitment period concept at issue in Kagenveama." Henderson, 455 B.R. at 209; see also In re Reed, 454 B.R. 790, 801 (Bankr.D.Or.2011) (noting that the Supreme Court has not "dealt with the interpretation of the applicable commitment period for above-median debtors who have no projected disposable income"). In Lanning, the Court was singularly focused on the term "projected" as that term modified "disposable income."7 "At its base, Kagenveama relied on the plain meaning of the statutory terms and their context and relationship to each other. The Supreme Court neither rejected that approach nor the conclusion that the circuit reached with regard to `applicable commitment period.'" Reed, 454 B.R. at 803; see Henderson, 455 B.R. at 209 ("An extended discussion of Kagenveama's analysis of the Code's text and context in light of Lanning ... would serve little purpose because [both] decisions focused on different portions of the Code").

Second, Lanning acknowledged the necessary relationship between the term "disposable income" defined in § 1325(b)(2) and (b)(3) and the undefined term "projected disposable income" used in (b)(1); the calculation of disposable income under (b)(2) and (b)(3) obviously informs the determination of projected disposable income. In contrast, the relationship between the term "applicable commitment period" as it is defined in (b)(4) and its use in (b)(1) is not so plain. Nothing in Lanning addresses how the ACP defined in (b)(4) should be applied to (b)(1).

Third, the definition of "projected" as used in defining "projected disposable income" is functionally independent of the determination of how the applicable commitment period affects the debtor's obligation under § 1325(b)(1). The terms "projected" and "applicable commitment period" are independent variables. The only things Lanning changed were the potential "inputs" for determining a debtor's projected disposable income. Kagenveama's essential conclusion remains untouched; namely, one who has no projected disposable income, however calculated under Lanning, is not subject to an applicable commitment period. Kagenveama, 541 F.3d at 877; Reed, 454 B.R. at 802.

We recognize that the Eleventh Circuit, considering the meaning of "applicable commitment period" as a matter of first impression, has held that "applicable commitment period" is a "temporal term that prescribes the minimum duration of a debtor's Chapter 13 bankruptcy plan" and in so holding, cited Lanning as supporting its conclusion:

Tennyson, 611 F.3d at 878-79.

While we need not determine whether we would reach the same conclusion were the question a matter of first impression, Tennyson does not demonstrate that our decision in Kagenveama is clearly irreconcilable with Lanning. Lanning does not, as Tennyson suggests, render "applicable commitment period" an "indeterminate term." Rather, under Kagenveama, once PDI has been calculated according to Lanning, "applicable commitment period" remains a fixed term of either three years or five years under (b)(4); it simply does not go into effect for debtors who have no projected disposable income.

Indeed, in Baud, the Sixth Circuit considered the opinions in both Kagenveama and Tennyson and acknowledged that "the plain-language arguments supporting each approach are nearly in equipoise." 634 F.3d at 351. Considering as a matter of first impression whether the applicable commitment period applies when a debtor has no projected disposable income, Baud simply found "the interpretation of § 1325(b) that applies the applicable commitment period to debtors with zero or negative projected disposable income to be more persuasive than the competing interpretation." Id. Significantly, Baud did not even cite to Lanning in the portion of its opinion that considered the textual meaning of "applicable commitment period." Id. at 350-51. Instead, because its textual analysis was inconclusive, "[f]or assistance in interpreting the statute, ... [it] turn[ed]... to the guideposts provided by the Supreme Court in Lanning and Ransom." Id. at 351. In that regard, Baud recognized the limited utility of Lanning as two of Lanning's interpretive guideposts — the lack of explicit multiplier language and pre-BAPCPA practice — were inapposite with respect to the meaning of "applicable commitment period" for debtors with no projected disposable income. Id. The only Lanning "guidepost" Baud found useful was its mandate to avoid "senseless results." Id. at 352. On this question, Baud "conclude[d] that applying the applicable commitment period to debtors with zero or negative projected disposable income would best serve BAPCPA's goal of ensuring that debtors repay creditors the maximum amount they can afford." Id. at 356-57. However, even on this point, Baud acknowledged a substantial difference of opinion among courts as to which interpretation was preferable. See id. at 354-56. While the court concluded that its interpretation best comported with Lanning's instruction to interpret BAPCPA so as to "maximiz[e] creditor recoveries," it did not hold that its was the only reasonable interpretation of the statute, nor did it hold that Lanning explicitly mandated a certain construction. Id. at 340. In short, Baud does not suggest that Lanning precludes a different conclusion, such as that reached in Kagenveama.8

b. Pre-Bankruptcy Abuse Prevention and Consumer Protection Act ("BAPCPA") Practice

Second, Kagenveama does not run afoul of Lanning's reliance upon pre-BAPCPA practice, Lanning, 130 S.Ct. at 2467, because as the Sixth Circuit observed in Baud, the question presented had never arisen pre-BAPCPA, 634 F.3d at 351. The precise scenario Kagenveama faced — the meaning of ACP for a debtor with no PDI — is one with no pre-BAPCPA analog. Such a scenario was a new question courts faced after BAPCPA, because the concept of a debtor with negative PDI did not previously exist. As one bankruptcy court has explained, "the pre-BAPCPA definition of `disposable income' calculated a real number rather than a statutory" formula; therefore, "a debtor with no positive number simply had no means to fund the added costs of a Chapter 13 plan." Alexander, 344 B.R. at 750; see also Baud, 634 F.3d at 351-52 ("[P]re-BAPCPA practice sheds no light here because `[t]o veterans of Chapter 13 practice, it runs afoul of basic principles to suggest that a debtor with no disposable income can nonetheless propose a confirmable plan[,] [y]et BAPCPA permits precisely that.'" (alterations in original) (quoting Alexander, 344 B.R. at 750)). BAPCPA's standardized formula created a new scenario in which "a debtor under the new `disposable income' test may show a zero or negative number, yet may be able to make the required showing that she actually has enough income to fund a confirmable plan." Alexander, 344 B.R. at 750. Thus, as Baud acknowledged, pre-BAPCPA practices offer no clear guidance as to whether any minimum plan length applies to debtors with negative projected disposable income.9

c. Avoiding Absurd or Senseless Results

Finally, under the third factor of Lanning's analytical framework, Lanning noted that the purpose of BAPCPA was to ensure that plans did not "deny creditors payments that the debtor could easily make." Lanning, 130 S.Ct. at 2476; see also Ransom v. FIA Card Servs., N.A., ___ U.S. ___, 131 S.Ct. 716, 729, 178 L.Ed.2d 603 (2011) (describing "BAPCPA's core purpose [as] ensuring that debtors devote their full disposable income to repaying creditors"); Baud, 634 F.3d at 356 (Lanning requires courts to "apply the interpretation that has the best chance of fulfilling BAPCPA's purpose of maximizing creditor recoveries"); H.R.Rep. No. 109-31(I), at 2 (2005), reprinted in 2005 U.S.C.C.A.N. 88, 89 (describing "[t]he heart of the bill's consumer bankruptcy reforms" as designed to "ensure that debtors repay creditors the maximum they can afford").10 Construction of the statute should not yield senseless results as measured against BAPCPA's purpose.

The bankruptcy court concluded that Kagenveama created absurd results that diverged from this purpose, as debtors could propose short plans that would deprive creditors of the opportunity to receive further payments if the debtors' financial circumstances improved within the five years after confirmation. However, Kagenveama's construction of "applicable commitment period" does not necessarily lead to senseless results in contravention of Congress's purpose. As Kagenveama found, the only circumstance in which a debtor can avoid the applicable commitment period is if she has no projected disposable income. At that point, the court has already determined that there are no such "payments that the debtor could easily make" as defined by the Bankruptcy Code. Lanning, 130 S.Ct. at 2476. As the bankruptcy court in Henderson explained, "the majority in Kagenveama noted that requiring a plan to remain open for a specific duration where there is no projected disposable income would do nothing to further § 1325(b)(1)'s stated purpose of verifying that debtors' `disposable income will be paid to unsecured creditors' because, under the workings of the Code, those debtors have no disposable income with which to make such payments." Henderson, 455 B.R. at 211 (quoting Kagenveama, 541 F.3d at 876).

Indeed, the fact that "projected disposable income" is to be determined under the more flexible forward-looking approach under Lanning adds assurance that able debtors will not escape their obligations even under Kagenveama's definition of "applicable commitment period." See Lanning, 130 S.Ct. at 2476 (highlighting the need to ensure that projected disposable income calculations give creditors all "payments that the debtor could easily make," but not to require more than they are capable of paying so as to "deny the protection of Chapter 13 to debtors who meet the chapter's main eligibility requirements").

The dissent highlights one potential gap in the statute's protections for creditors — certain future increases in a debtor's income may not be sufficiently "certain" to be included in the debtor's projected disposable income under Lanning. However, this risk is minimal and mitigated by the fact that the applicable commitment period is not the only weapon in creditors' arsenal to ensure that Chapter 13 plans provide for the maximum payments debtors can afford. For example, debtors are required to propose plans in good faith according to § 1325(a)(3), which, although subject to some dispute post-BAPCPA, has generally been applied using a totality of the circumstances test to determine if debtors have "`unfairly manipulated the Bankruptcy Code, or otherwise proposed their [C]hapter 13 plan in an inequitable manner.'" In re Briscoe, 374 B.R. 1, 22 (Bankr.D.D.C. 2007) (brackets removed) (quoting Goeb v. Heid (In re Goeb), 675 F.2d 1386, 1390 (9th Cir.1982)); see In re Marti, 393 B.R. 697, 700 (Bankr.D.Neb.2008) (finding lack of good faith under § 1325(a)(3) and (a)(7) where the debtor "went from no income prior to filing to substantial income immediately after filing" and could therefore afford to pay his creditors despite his lack of disposable income according to the statutory test).11 "Other confirmation requirements would include the best-interests test set forth in § 1325(a)(4)." Baud, 634 F.3d at 352 n. 19 (citing 11 U.S.C. § 1325(a)(4) (providing that, in order for a Chapter 13 plan to be confirmable, "the value, as of the effective date of the plan, of property to be distributed under the plan on account of each allowed unsecured claim is not less than the amount that would be paid on such claim if the estate of the debtor were liquidated under [C]hapter 7 of this title on such date")).

In addition, courts have used the "absurd results" rationale to justify conclusions on both sides of this debate. See, e.g., In re Williams, 394 B.R. 550, 570 (Bankr.D.Colo.2008) (adopting a monetary approach to the applicable commitment period because it "allows the possibility that a debtor will pay off his unsecured creditors more quickly," increases the present value of the payments, and "reduces the chances of a default on plan payments"). Some courts have rejected a strict temporal approach to the applicable commitment period for debtors without projected disposable income, reasoning that such debtors

In re Mathis, 367 B.R. 629, 634 (Bankr. N.D.Ill.2007).

Arguably, there are potentially perverse results for creditors when debtors who have no obligation to propose any payments to unsecured creditors because they have no projected disposable income, are nonetheless forced to propose only 60-month plans in which to pay priority and administrative claims. As the bankruptcy court in In re Burrell explained:

In re Burrell, No. 08-71716, 2009 WL 1851104, at *4-5 (Bankr.C.D.Ill. June 29, 2009).

In sum, there is no singular view as to which interpretation of the ACP would best fulfill BAPCPA's purpose. We cannot say that Kagenveama's interpretation of the ACP and its effect under § 1325(b)(1) will lead to senseless results in contravention of Congress's purpose in enacting the BAPCPA. In this regard, Kagenveama is not inconsistent with Lanning.

V. CONCLUSION

As one court has noted, "many jurists and commentators have written ... ably on this issue" and "cogent arguments, both of statutory construction and of bankruptcy policy, have certainly been made" on all sides. In re Moose, 419 B.R. 632, 635 (Bankr.E.D.Va.2009). Were we writing on a clean slate, the contrary conclusion reached by the Sixth and Eleventh Circuits on this question would deserve consideration. The Trustee raises legitimate policy considerations as to why a mandated plan length might be desirable even when debtors have no projected disposable income. The dissent highlights some of these legitimate policy concerns. However, we do not write on a clean slate. Instead, our analysis is constrained by our own prior authority, which we are bound to follow unless it is clearly irreconcilable with Lanning. We are not convinced that Lanning has "undercut the theory or reasoning underlying [Kagenveama] in such a way that the cases are clearly irreconcilable." Gammie, 335 F.3d at 900 (emphasis added). Thus, only the Supreme Court or an en banc panel of this court may revisit Kagenveama's holding regarding the applicable commitment period.

Accordingly, we conclude that the bankruptcy court erred in disregarding Kagenveama.

REVERSED AND REMANDED.

GRABER, Circuit Judge, dissenting:

I respectfully dissent. In my view, we are not compelled to follow Maney v. Kagenveama (In re Kagenveama), 541 F.3d 868 (9th Cir.2008), because it is "clearly irreconcilable" with Hamilton v. Lanning, ___ U.S. ___, 130 S.Ct. 2464, 177 L.Ed.2d 23 (2010). See Miller v. Gammie, 335 F.3d 889, 900 (9th Cir.2003) (en banc) (stating principle that a three-judge panel is not bound by a prior circuit precedent in this circumstance).

Kagenveama created a rule under which our circuit set no minimum duration on plans confirmable by certain debtors, such as the ones in this case. See 541 F.3d at 877 (holding that, when a debtor's projected disposable income was negative, the applicable commitment period "did not apply" and offering no substitute durational requirement).1 That aspect of Kagenveama is clearly irreconcilable with Lanning, which interprets 11 U.S.C. § 1325(b) (the "disposable income test") as a vehicle for achieving the congressional intent of making debtors pay as much as they can, but no more, over a fixed period, while allowing discretion to adjust the payout up or down as required by the debtor's evolving financial situation. In Lanning, the Court rejected the practical consequences resulting from a "mechanical" calculation of projected disposable income, reasoning:

130 S.Ct. at 2475-76 (emphases added).

Lanning involved pre-confirmation adjustments to plan payments, "to account for known or virtually certain changes" in a debtor's income. Id. at 2475. But, to avoid "deny[ing] creditors payments that the debtor could easily make," Lanning's logic must also require a mechanism for post-confirmation adjustments for unforeseen increases in a debtor's income.2 That mechanism is the plan modification procedure of 11 U.S.C. § 1329. See Kagenveama, 541 F.3d at 877 ("If [the debtor's] income changes in the future before completion of the plan, the Trustee or the holder of an unallowed secured claim may seek modification of the plan under § 1329."). That mechanism would be illusory unless a plan has some minimum duration.3 See id. at 879 (Bea, J., dissenting in part) ("The five-year requirement of § 1325 ... is a necessary component of plan modification. If the plan is not continued for a five-year period (post-confirmation), an unsecured creditor who discovers the debtor's finances have dramatically improved will find that there is no extant plan to modify.").4 Accordingly, Lanning precludes any reading, such as Kagenveama's, that imposes no minimum duration on a Chapter 13 plan.

The majority suggests that my interpretation ignores the "`plain language of the Bankruptcy Code'" and does so merely for reasons of policy. Maj. op. at 1033-34 n. 8 (quoting Kagenveama, 541 F.3d at 877). Not so. My approach is motivated not by policy concerns, but by fidelity to Lanning's view of congressional intent. See United States v. Ron Pair Enters., 489 U.S. 235, 242, 109 S.Ct. 1026, 103 L.Ed.2d 290 (1989) ("The plain meaning of legislation should be conclusive, except in the rare cases in which the literal application of a statute will produce a result demonstrably at odds with the intentions of its drafters. In such cases, the intention of the drafters, rather than the strict language, controls." (emphasis added) (citation, internal quotation marks, and brackets omitted)).

The need for a minimum plan duration, then, leads to the conclusion that Kagenveama cannot be reconciled with Lanning and leaves it to this court to decide what that duration should be in the case of a debtor with negative disposable income. In my view, we should answer that question by looking to the statutory provision that comes closest to setting a minimum plan duration — the "applicable commitment period" definition. That is, so long as some minimum duration is necessary, it makes sense to derive that duration from the definition of "applicable commitment period," as the Sixth and Eleventh Circuits have done. Baud, 634 F.3d 327; Whaley v. Tennyson (In re Tennyson), 611 F.3d 873 (11th Cir.2010). Furthermore, the legislative history of the disposable income test supports that approach:

H.R.Rep. No. 109-31(I), § 318, at 79 (2005), reprinted in 2005 U.S.C.C.A.N. 88, 146 (emphasis added). The quoted section is confusingly worded, but the title suggests that above-median debtors are to be held to a five-year minimum plan duration without regard to their expenses or disposable income, unless they pay unsecured claims in full over a shorter period.

The majority admits that, as between the two competing statutory interpretations at the heart of this case, neither is necessarily more correct than the other. Maj. op. at 1033, 1038. The majority also concedes that, were it "writing on a clean slate, the contrary conclusion reached by the Sixth and Eleventh Circuits on this question would deserve consideration." Id. at 1038. Because our circuit's rule is clearly irreconcilable with later Supreme Court precedent, we are writing on a clean slate. In so doing, we should consider most strongly the intent of Congress (to require debtors to pay creditors what they can readily afford) and the need for national uniformity in the application of the federal bankruptcy laws. Those two factors compel the conclusion that Kagenveama no longer is good law. I would therefore adopt the holdings of our sister circuits and affirm the bankruptcy court's decision.
