    SUMMARY **
    ERISA
    The panel reversed the district court’s dismissal, on the
    ground of equitable estoppel, of an ERISA action in which
    David Wong, Trustee of the Anaplex Corporation Employee
    Stock Ownership Plan, sought equitable and declaratory
    relief against Danette K. Flynn-Kerper, the holder of a
    promissory note from Anaplex.
    Bernard Kerper, former trustee of the ESOP and late
    husband of Flynn-Kerper, acquired the promissory note in
    exchange for shares of Anaplex stock he sold to the ESOP.
    Alleging that the ESOP had paid greater than “adequate
    consideration” for the shares, Wong sought an adjustment to
    the purchase price and a declaration that the ESOP had
    overpaid. Flynn-Kerper moved to dismiss, arguing that
    Wong was equitably estopped from asserting his claims
    against her, based on an agreement between them that she
    alleged settled a prior lawsuit in which she had alleged
    Anaplex’s failure to repay promissory notes, including a
    note that Anaplex issued in connection with the challenged
    stock sale. The district court granted the motion to dismiss,
    concluding that ERISA did not bar promissory or equitable
    estoppel because Flynn-Kerper was not making a claim
    pursuant to the ERISA agreement, but instead was seeking
    to rebuff Wong’s claim for reformation of the promissory
    note.

    WONG V. FLYNN-KERPER                       3
    Reviewing under a summary judgment standard, the
    panel held that Flynn-Kerper could not equitably estop
    Wong, the ERISA Trustee, because doing so would
    contradict the clear terms of the ESOP. The panel held that,
    in addition to satisfying the traditional equitable estoppel
    requirements, a party bringing a federal equitable estoppel
    claim in the ERISA context must also allege:
    (1) extraordinary circumstances; (2) that the provisions of
    the plan at issue were ambiguous such that reasonable
    persons could disagree as to their meaning or effect; and
    (3) that the representations made about the plan were an
    interpretation of the plan, not an amendment or modification
    of the plan. The panel held that a party cannot maintain a
    federal equitable estoppel claim against a trust fund where
    recovery on the claim would contradict written plan
    provisions. Here, if Wong were correct that the Anaplex
    shares were overvalued during an appraisal, applying
    equitable estoppel would require Wong to pay Flynn-Kerper
    greater than the fair market value of the shares on the date of
    purchase. This would contravene Section 6(d) of the ESOP,
    which required that the shares be purchased at fair market
    value on the date of purchase. Joining the Fourth Circuit, the
    panel held that the defensive use of equitable estoppel is
    barred when estopping the plaintiff would contradict an
    ERISA plan’s express terms. The panel therefore reversed
    the district court’s judgment and remanded.

    Defendant-Appellee.
    OPINION
    BENNETT, Circuit Judge:
    In this ERISA case, Defendant Danette Flynn-Kerper
    succeeded in equitably estopping ERISA Trustee Plaintiff
    David Wong in his suit seeking equitable and declaratory
    relief, even though her equitable estoppel claim contradicted
    the written provisions of the ERISA plan. But “a party
    cannot maintain a federal equitable estoppel claim against a
    trust fund where recovery on the claim would contradict
    written [ERISA] plan provisions,” Greany v. W. Farm
    Bureau Life Ins., 
    973 F.2d 812
    , 821 (9th Cir. 1992), or where
    it “would, as a practical matter, result in an amendment or
    modification of a plan,” Gabriel v. Alaska Elec. Pension
    Fund, 
    773 F.3d 945
    , 956 (9th Cir. 2014).
    Flynn-Kerper tries to reframe the issue as whether a
    defendant can equitably estop a plaintiff contrary to the
    terms of an ERISA plan. This is a distinction without a
    difference. “The actuarial soundness of pension funds is,
    absent extraordinary circumstances, too important to permit
    trustees to obligate the fund to pay pensions to persons not
    entitled to them under the express terms of the pension plan,”
    
    id.
     (citation omitted), whether those “persons” be plaintiffs
    or defendants. Flynn-Kerper cannot equitably estop the
    ERISA Trustee from affirmatively enforcing the terms of the
    ERISA plan. For this and other reasons, we reverse.
    WONG V. FLYNN-KERPER                              5
    I. FACTS
    Wong, in his capacity as Trustee of the Anaplex
    Corporation Employee Stock Ownership Plan (ESOP), is
    suing Flynn-Kerper, in her individual capacity as the present
    holder of a $1,000,654.20 promissory note from Anaplex.
    Bernard Kerper, the former trustee of the ESOP and the
    late husband of Flynn-Kerper, originally acquired that
    promissory note in April 2015, in exchange for shares of
    Anaplex stock he sold to the ESOP. Kerper—negotiating
    the purchase price for both himself and the ESOP—based
    the purchase price for this conflicted transaction on a
    valuation conducted by independent appraiser Brian Turner.
    Turner determined the fair market value of the Anaplex
    shares, in seeming compliance with the ESOP’s
    requirements. In particular, consistent with the ERISA
    requirements for transactions between an ERISA trust and
    its trustee, 1 Section 6(d) of the ESOP provides:
    Purchases of Company Stock by the Trust
    will be made at a price which . . . does not
    exceed the fair market value of such
    Company Stock . . . . [I]f the purchase of
    Company Stock is from a “disqualified
    1
    Section 406(a)(1)(A) of ERISA defines the “sale . . . of any
    property between the plan and a party in interest” as a prohibited
    transaction. 
    29 U.S.C. § 1106
    (a)(1)(A). Yet § 408(b)(17)(A) makes an
    exception for such a transaction where “the plan receives no less, nor
    pays no more, than adequate consideration.” Id. § 1108(b)(17)(A). And
    § 408(e)(1) makes an exception for the “acquisition . . . by a plan of
    [company shares] . . . if such acquisition . . . is for adequate
    consideration.” Id. § 1108(e)(1). Section 3(18) defines “adequate
    consideration” as “the fair market value of the asset as determined in
    good faith by the trustee or named fiduciary pursuant to the terms of the
    plan.” Id. § 1002(18).
    6                   WONG V. FLYNN-KERPER
    person” as defined in Code Section
    4975(e)(2), the fair market value shall be
    determined as of the date of purchase. 2
    To ensure a proper determination of fair market value, the
    ESOP also provides that “[t]he determination of fair market
    value . . . shall be made by an independent appraiser.”
    Although Kerper seemed to follow these requirements
    by hiring Turner to conduct an independent valuation of the
    shares, Wong alleges that the ESOP paid more than fair
    market value for Kerper’s shares. First, Wong claims that
    Turner was unaware of an omission in Anaplex’s accounting
    records caused by Kerper. Kerper had written checks to
    himself—or instructed employees to issue checks to or make
    payments for him—out of Anaplex’s general checking
    account. This resulted in Kerper owing Anaplex more than
    $1,000,000, a debt that was carried on Anaplex’s books as
    an asset. Wong alleges that at the time Anaplex hired Turner
    to value the shares, Kerper knew that even though the debt
    was carried on the books as a real asset of Anaplex, the debt
    was in default and would be uncollectible by the time of the
    April 2015 transaction. Wong also alleges that Kerper knew
    that no one had informed Turner of that fact. Thus,
    according to Wong, Kerper knew that Turner’s appraisal
    necessarily overvalued the company by more than
    $1,000,000, the difference between a debt that was fully
    collectible and one that was in default and uncollectible.
    Wong contends that when Kerper died, four months after the
    2
    The parties do not dispute that Kerper was a “disqualified person”
    and therefore fair market value should have been determined as of the
    date of purchase.
    WONG V. FLYNN-KERPER                     7
    April 2015 sale, the uncollectible amount he owed Anaplex
    was $1,085,876.29 plus interest.
    Second, Wong alleges that Kerper failed to disclose to
    Turner that Anaplex was being investigated by the U.S.
    Environmental Protection Agency (EPA) and was thus
    incurring hundreds of thousands of dollars in legal fees and
    facing hundreds of thousands of additional dollars in
    potential fines and penalties at the time of the valuation,
    further contributing to Turner’s overvaluing the shares.
    Wong alleges that without this information, Turner’s
    valuation was “materially flawed” and resulted in a purchase
    price in excess of the fair market value—contrary to the
    ESOP’s terms. In his declaration, attached to Wong’s
    opposition to the motion to dismiss, Turner stated that when
    he prepared the valuation, he did not know that the loans—
    which he treated as assets of Anaplex—were in default and
    would become legally uncollectible prior to the April 2015
    sale. He also stated he did not know of the EPA
    investigation. He explained that both pieces of information
    would have been material to his valuation and would have
    resulted in a valuation reflecting a reduced value of the
    shares, which were probably “worth significantly less than
    the $93.87 purchase price used by Mr. Kerper.”
    Wong thus brought this action in May 2018. He sought
    equitable relief pursuant to 
    29 U.S.C. § 1132
    (a)(3)—ERISA
    § 502(a)(3)—because the ESOP had paid greater than
    “adequate consideration” for the shares. Wong sought an
    adjustment to the purchase price and a declaration that the
    ESOP had overpaid.
    Flynn-Kerper moved to dismiss for failure to state a
    claim. She argued that Wong was equitably estopped from
    asserting his claims against her, based on an agreement
    8                WONG V. FLYNN-KERPER
    between them that she alleged settled a prior lawsuit. Flynn-
    Kerper had sued Anaplex in state court in 2016, alleging
    Anaplex’s failure to repay various promissory notes,
    including the April 2015 note that Anaplex issued in
    connection with the challenged stock sale. Wong and
    Anaplex then entered into a Note Repayment Agreement
    (NRA) with Flynn-Kerper, (1) establishing a new repayment
    schedule for the April 2015 promissory note and
    (2) requiring Flynn-Kerper to dismiss her first four causes of
    action (but not her claim for overdue payments on the April
    2015 note). In October 2017, Flynn-Kerper dismissed all her
    claims. Though the NRA does not specify whether the
    required dismissals were to be with or without prejudice,
    Flynn-Kerper dismissed without prejudice, including the
    claim for overdue payments on the April 2015 note.
    Flynn-Kerper and Wong do not agree on four facts
    relating to the NRA. First, regarding Wong’s intent in
    entering the NRA, Flynn-Kerper argues that Wong entered
    the agreement to “confirm” the amount owed and the
    ESOP’s obligation to pay it. Wong argues that the “NRA
    did nothing more than acknowledge the original obligation
    of the ESOP under the Promissory Note” and “in no way . . .
    ‘confirmed[]’ . . . that the Purchase Price represented no
    more than adequate consideration for the Shares as of the
    Transaction date.”
    Second, regarding Wong’s knowledge when entering the
    agreement, Flynn-Kerper argues that “Wong was on notice
    of the unenforceability of the debt given the State Action was
    actively litigating the propriety and enforceability of that
    alleged debt,” and that the “same can be said of Wong’s
    knowledge of the EPA investigation, fines, and litigations.”
    Wong responds that it was his “honest belief . . . at the time
    he entered into the NRA that the Debt would be recovered,”
    WONG V. FLYNN-KERPER                                 9
    and that “although [he] was aware of the existence of the
    EPA investigation” prior to entering the NRA, he was
    unaware of Kerper’s failure to report that investigation to
    Turner, the pertinent fact for purposes of this litigation, until
    later.
    Third, regarding Flynn-Kerper’s knowledge when
    entering the agreement, Flynn-Kerper asserts (though not in
    a declaration) that she “never would have signed the NRA if
    she were aware [Wong] intended not to pay her yet continue
    to litigate the value of the Note owed to her.” Wong counters
    that it “was known to [Flynn-Kerper] at the time she
    dismissed the State Case . . . that the ESOP would most
    likely be bringing a federal claim challenging the Purchase
    Price of the Shares,” citing language in the NRA that he
    believes “expressly retained . . . the right to later bring
    claims.” 3
    Finally, regarding Flynn-Kerper’s reliance on the NRA
    in dismissing her claims in the state action, she argues she
    did so “[a]s a result of and in reliance upon the NRA and
    negotiations.” Wong responds that “it cannot reasonably be
    argued that [Flynn-Kerper] reasonably and foreseeably
    relied on, or was enticed by, the NRA when she voluntarily
    chose to dismiss claims in the State Case.” He bases this
    assertion on (1) Flynn-Kerper’s five-month delay between
    entering the NRA and filing the request for dismissal
    3
    Wong points to language in the NRA stating that “[t]he Parties
    hereby acknowledge and agree that [the NRA] does not fully settle all
    outstanding claims existing between the Executor, the ESOP, and
    Anaplex Corporation.” He also points to language stating that
    “payments shall continue to be made to [Flynn-Kerper] until further . . .
    order of the Court” and that “[n]o modification, amendment or waiver of
    any of the [NRA] provisions . . . shall be binding . . . unless . . . ordered
    by the Court.”
    10                  WONG V. FLYNN-KERPER
    (despite that the NRA required her to dismiss the first four
    causes of action in five days); (2) the fact that the NRA did
    not require her to dismiss the cause of action involving the
    April 2015 note; (3) the fact that Flynn-Kerper dismissed all
    the claims without prejudice in the state action, including the
    cause of action involving the April 2015 note; 4 and (4) her
    willingness to dismiss the case even after receiving an email
    from Wong’s counsel one day prior stating, “the amount due
    on the note is not being warrantied that it is not subject to
    change to the extent the [ESOP] over-paid.” 5
    Other than the argument that Flynn-Kerper did not rely
    on the NRA in dismissing her claims, Wong raised these
    factual disputes in his opposition to the motion to dismiss,
    which he supported with his declaration, as well as
    declarations from Turner and the president of Anaplex.
    Wong also requested that the district court take judicial
    notice of the state court decision finding Kerper’s debt to
    Anaplex legally uncollectible after the parties entered the
    NRA.
    The district court granted Flynn-Kerper’s motion to
    dismiss without leave to amend, acknowledging the factual
    disagreements between Wong and Flynn-Kerper but finding
    4
    At argument, we asked Flynn-Kerper’s counsel whether the NRA
    required dismissal with or without prejudice. However, she was unable
    to answer, even though it is obvious that whether the NRA’s dismissal
    clause required permanent or temporary dismissal of claims is relevant
    to whether the NRA settled the ESOP’s note repayment obligations.
    5
    Furthermore, the evidence of Flynn-Kerper’s knowledge that
    Wong might later bring a lawsuit relating to the April 2015 promissory
    note is also relevant to whether she relied on the NRA when she
    dismissed her claims in the state action.
    WONG V. FLYNN-KERPER                            11
    Wong’s arguments “unconvincing.” 6 The district court thus
    concluded:
    [T]here is no question that [Wong] made a
    clear and unambiguous promise to pay
    [Flynn-Kerper the outstanding balance on the
    April 28, 2015 note, plus interest. Flynn-
    Kerper] reasonably and foreseeably relied on
    this promise when she voluntarily dismissed
    her various claims in state court. Permitting
    [Wong] to now renege on this agreement and
    reform the promissory note would punish
    [Flynn-Kerper] for her reliance on [Wong’s]
    representation. This is an impermissible
    outcome.
    Wong then filed a motion for reconsideration, raising
    many of the same arguments as in his opposition to the
    motion to dismiss, along with several new ones: (1) that a
    trust may not be equitably estopped if doing so contradicts
    written ERISA plan provisions; and (2) that Flynn-Kerper
    did not rely on the NRA in dismissing all of her state court
    claims (for the reasons already discussed).
    The district court addressed each of these arguments on
    the merits, including those raised for the first time in the
    motion for reconsideration, and it denied the motion.
    Regarding the issue of ERISA preemption, the district court
    adopted Flynn-Kerper’s position that ERISA “does not bar
    6
    The district court left almost all of Wong’s arguments unaddressed,
    including that the NRA did “not fully settle all outstanding claims
    existing between” him and Flynn-Kerper, and that the NRA did not
    require Flynn-Kerper to dismiss the claim pertaining to the April 2015
    promissory note.
    12                WONG V. FLYNN-KERPER
    promissory or equitable estoppel in this context,” where
    “Defendant is not making a claim pursuant to the [ERISA]
    agreement, but is instead seeking to rebuff Plaintiff’s own
    claim for reformation of a promissory note.” According to
    the district court, “estoppel [has] no effect whatsoever on the
    plan’s written provisions” in such a scenario.
    Wong now appeals to this court, where we review the
    Rule 12(b)(6) dismissal de novo. Ariz. Students’ Ass’n v.
    Ariz. Bd. of Regents, 
    824 F.3d 858
    , 864 (9th Cir. 2016).
    II. DISCUSSION
    When “matters outside the pleadings are presented to and
    not excluded by the court” on a Rule 12(b)(6) motion, “the
    motion must be treated as one for summary judgment under
    Rule 56.” Fed. R. Civ. P. 12(d). Thus, because both parties
    submitted exhibits, and because Wong submitted
    declarations, we look at the findings of the district court
    under a summary judgment standard. Under that standard, a
    district court may dismiss a case only if there is “no genuine
    dispute as to any material fact,” Fed. R. Civ. P. 56(a),
    viewing the evidence “in the light most favorable to the
    opposing party,” Adickes v. S.H. Kress & Co., 
    398 U.S. 144
    ,
    157 (1970).
    Equitable estoppel applies if the party to be estopped
    knew the facts and intended for his conduct to be acted on,
    and if the party asserting estoppel was ignorant of the true
    facts and relied on the other party’s conduct to her injury.
    Ellenburg v. Brockway, Inc., 
    763 F.2d 1091
    , 1096 (9th Cir.
    1985), abrogated on other grounds as recognized by
    Watkins v. Westinghouse Hanford Co., 
    12 F.3d 1517
     (9th
    Cir. 1993). Thus, applying equitable estoppel to Wong’s
    claim would raise questions about Wong’s knowledge and
    intent when entering the NRA, and Flynn-Kerper’s
    WONG V. FLYNN-KERPER                              13
    knowledge when entering the NRA and reliance on the NRA
    in dismissing her claims in the state action. All of these are
    factual issues. See Simmons v. United States, 
    805 F.2d 1363
    ,
    1368 (9th Cir. 1986) (knowledge is an issue of fact); Nat’l
    Union Fire Ins. v. Argonaut Ins., 
    701 F.2d 95
    , 97 (9th Cir.
    1983) (contractual intent is an issue of fact); Atkins, Kroll
    (Guam), Ltd. v. Cabrera, 
    295 F.2d 21
    , 23 (9th Cir. 1961)
    (reliance is an issue of fact). And all are subject to genuine
    dispute. Under the appropriate Rule 56 standard, then, even
    assuming estoppel principles were available in the ERISA
    context presented here, the district court could not equitably
    estop Wong’s claims at this stage of the proceedings merely
    because it found Wong’s position “unconvincing.” 7
    7
    The same holds true for Flynn-Kerper’s arguments that we can
    affirm on grounds not addressed by the district court. For example,
    Flynn-Kerper argues that we can dismiss this case under the doctrine of
    judicial estoppel, which bars inconsistent positions by the same party in
    different court proceedings. But the parties have a factual disagreement
    about whether the NRA reflects a prior inconsistent position on Wong’s
    part. See New Hampshire v. Maine, 
    532 U.S. 742
    , 750 (2001) (naming
    clear inconsistency in a party’s earlier and later positions before a court
    as one of “several factors typically inform[ing] the decision whether to
    apply [judicial estoppel] in a particular case”). This factual dispute
    cannot be resolved at this stage of the proceedings.
    Flynn-Kerper also argues that Wong should be barred from seeking
    equitable relief because he has “unclean hands” and acted in “bad faith,”
    characterizing Wong’s lawsuit as “nothing more than the ESOP’s
    devious attempt to completely avoid its contractual obligation to pay for
    stock that it purchased from [Kerper].” But whether Wong has “unclean
    hands” or acted in bad faith turns on his intent in entering the NRA, as
    well as his knowledge before doing so. See Fuddruckers, Inc. v. Doc’s
    B.R. Others, Inc., 
    826 F.2d 837
    , 847 (9th Cir. 1987) (“To prevail [on a
    defense of unclean hands], the defendant must demonstrate that the
    plaintiff’s conduct is inequitable . . . .”).
    14                   WONG V. FLYNN-KERPER
    But more fundamentally, the district court also erred in
    its ERISA analysis. Flynn-Kerper cannot equitably estop
    Wong, the ERISA Trustee, because doing so would
    contradict the clear terms of the ESOP. “[F]ederal equitable
    estoppel principles can, in certain circumstances, apply to
    some claims arising under ERISA.” 8 Greany, 
    973 F.2d at 821
     (emphasis added). However, in addition to satisfying
    the traditional equitable estoppel requirements, a party
    bringing a federal equitable estoppel claim in the ERISA
    context must also allege: “(1) extraordinary circumstances;
    (2) that the provisions of the plan at issue were ambiguous
    such that reasonable persons could disagree as to their
    meaning or effect; and (3) that the representations made
    about the plan were an interpretation of the plan, not an
    Finally, Flynn-Kerper argues that Wong’s claims are barred by the
    statute of limitations, which she believes expired on April 28, 2018, at
    the latest. But again, whether the statute of limitations has run on
    Wong’s claim likely turns, at least in part, on when Wong acquired the
    knowledge that Turner’s valuation was too low and whether Kerper
    concealed information, which are both disputed facts. See 
    29 U.S.C. § 1113
     (“No action may be commenced under this subchapter . . . after
    . . . three years after the earliest date on which the plaintiff had actual
    knowledge of the breach or violation; except that in the case of . . .
    concealment, such action may be commenced not later than six years
    after the date of discovery of such breach or violation.”).

    In contrast, promissory estoppel never applies in the ERISA
    context. See DeVoll v. Burdick Painting, Inc., 
    35 F.3d 408
    , 412 (9th Cir.
    1994). Wong contends that the district court committed reversible legal
    error by applying promissory estoppel, rather than equitable estoppel. It
    is unclear from the district court’s decision whether it intended to apply
    equitable estoppel but used the wrong terminology, or whether it
    intended to apply the related doctrine of promissory estoppel, which
    would have been an error. We assume, therefore, that the reference to
    promissory estoppel was a mistake in terminology. But for the reasons
    explained below, applying equitable estoppel in this context was
    likewise error.

    amendment or modification of the plan.” Gabriel, 773 F.3d
    at 957 (quotation marks and citation omitted). “[A] party
    cannot maintain a federal equitable estoppel claim against a
    trust fund where recovery on the claim would contradict
    written plan provisions.” Greany, 
    973 F.2d at 821
    .
    The policy concerns motivating these requirements are
    straightforward. “The actuarial soundness of pension funds
    is, absent extraordinary circumstances, too important to
    permit trustees to obligate the fund to pay pensions to
    persons not entitled to them under the express terms of the
    pension plan.” Gabriel, 773 F.3d at 956 (citation omitted).
    “If the effective terms of the plan may be altered by
    transactions between officers of the plan and individual plan
    participants . . . , the rights and legitimate expectations of
    third parties to retirement income may be prejudiced.”
    Bloemker v. Laborers’ Loc. 265 Pension Fund, 
    605 F.3d 436
    , 440 (6th Cir. 2010) (citation omitted). Even if the use
    of equitable principles might foster the fair treatment of one
    litigant, we will not use those principles to modify the plan
    and thereby unfairly treat the other plan participants. Cf.
    Kramer v. Toyota Motor Corp., 
    705 F.3d 1122
    , 1133 (9th
    Cir. 2013) (“The ‘linchpin’ for equitable estoppel is
    fairness.”).
    Here, allowing Flynn-Kerper to assert her equitable
    estoppel claim against Wong would contradict the clear
    terms of the ESOP. If Wong is correct that Turner
    overvalued the Anaplex shares during his appraisal, applying
    equitable estoppel would require Wong to pay Flynn-Kerper
    greater than the fair market value of the shares on their date
    of purchase. This would contravene Section 6(d) of the
    ESOP, which requires that the shares be purchased at fair
    market value on the date of purchase.
    16                   WONG V. FLYNN-KERPER
    Flynn-Kerper contends that the “defense of estoppel is
    never addressed by the body of case law Wong cites to.” She
    tries to distinguish her use of equitable estoppel against
    Wong by emphasizing that she is using it as “a shield to
    protect against a claim asserted by the ESOP,” rather than
    “an offensive tool to extract benefits from the plan.” While
    our circuit has yet to decide whether a defense of equitable
    estoppel is barred in an ERISA case brought by the ERISA
    plan, the same reasons for prohibiting equitable estoppel
    apply to both the affirmative use and the “defensive” use.
    Regardless of whether it is a plaintiff or a defendant who
    seeks to estop a trustee from enforcing an ESOP’s terms,
    such estoppel would come at the expense of plan
    participants, who have relied on the plan terms and who are
    not responsible for the conduct that gave rise to the claimed
    estoppel. 9 See Bloemker, 
    605 F.3d at 440
    .
    Furthermore, were it relevant, the distinction Flynn-
    Kerper draws between the use of equitable estoppel as an
    “offensive tool” and equitable estoppel as a “shield” would
    be inapplicable here. Wong is acting preemptively in
    advance of Flynn-Kerper’s attempt to collect on the note. If
    Wong had done nothing and refused to pay on the note,
    Flynn-Kerper would have had to sue again to collect. Wong
    would have interposed the ESOP terms as a defense, and
    Flynn-Kerper would have argued that Wong was equitably
    estopped. That Wong acted first does not change the
    analysis. A party, whether a plaintiff or a defendant, cannot

    “[E]stoppel requires reasonable or justifiable reliance by the party
    asserting the estoppel.” Sprague v. Gen. Motors Corp., 
    133 F.3d 388
    ,
    404 (6th Cir. 1998) (en banc). A “party’s reliance can seldom, if ever,
    be reasonable or justifiable if it is inconsistent with the clear and
    unambiguous terms of plan documents available to or furnished to the
    party.”

    use equitable estoppel to contradict the express terms of an
    ERISA plan in litigation with the plan. 10
    In so holding, we join the Fourth Circuit, which bars the
    defensive use of equitable estoppel when estopping the
    plaintiff would contradict an ERISA plan’s express terms.
    See Ret. Comm. of DAK Ams. LLC v. Brewer, 
    867 F.3d 471
    ,
    485 (4th Cir. 2017). And we defer to “ERISA’s focus on
    what a plan provides,” consistent with Supreme Court
    precedent. US Airways, Inc. v. McCutchen, 
    569 U.S. 88
    , 100
    (2013) (declining to apply “equitable defenses alleging
    unjust enrichment,” 
    id. at 95
    , when doing so would
    contradict “the plan’s clear terms,” 
    id. at 98
    , and noting that
    this holding “fits lock and key with ERISA’s focus on what
    a plan provides,” 
    id. at 100
    ). Equitable estoppel has no place
    10
    Flynn-Kerper cites two cases for the proposition that ERISA plans
    should not bar equitable claims by third parties. See The Meadows v.
    Emps. Health Ins., 
    47 F.3d 1006
    , 1009 (9th Cir. 1995); Cath. Healthcare
    West-Bay Area v. Seafarers Health & Benefits Plan, 321 F. App’x 563,
    564 (9th Cir. 2008). But Flynn-Kerper is not a “third party” here. As
    discussed above, her husband was the former trustee of the ESOP and
    allegedly withheld information that would have materially affected the
    valuation of his shares. “The key to distinguishing between what ERISA
    preempts and what it does not lies . . . in recognizing that the statute
    comprehensively regulates certain relationships: for instance, the
    relationship between plan and plan member, between plan and employer,
    between employer and employee . . . , and between plan and trustee.”
    Gen. Am. Life Ins. v. Castonguay, 
    984 F.2d 1518
    , 1521 (9th Cir. 1993)
    (second emphasis added). Thus, ERISA supersedes laws and equitable
    principles that would otherwise interfere with a trustee’s relationship to
    the trust, given that “ERISA already regulates the trust-trustee
    relationship.” 
    Id. at 1522
    . That Flynn-Kerper is a successor in interest
    to a prior trustee—her late husband—who is alleged to have improperly
    benefited from an overvaluation of the shares, rather than the original
    trustee, does not alter the conclusion that she is a non–third party whose
    relationship to the ESOP is governed by the ESOP’s terms.

    at any stage in this litigation, and the district court erred in
    dismissing the case based on it. 11
    REVERSED AND REMANDED. 12
    11
    Flynn-Kerper does not argue that Wong waived this issue by
    failing to raise it until his motion for reconsideration. Flynn-Kerper thus
    waived the defense of waiver. See Gallardo v. United States, 
    755 F.3d 860
    , 865 (9th Cir. 2014) (“Because the [appellee] failed to argue waiver
    in its answering brief, its waiver argument is itself waived.”). Even were
    that not the case, “we may exercise discretion to consider a waived issue
    in certain cases, one such case being when the issue presented is a pure
    question of law.” Self-Realization Fellowship Church v. Ananda Church
    of Self-Realization, 
    59 F.3d 902
    , 912 (9th Cir. 1995). Because ERISA
    preemption is a question of law, we may exercise our discretion to
    consider the issue on appeal—especially given that the district court had
    the opportunity to consider and did address the issue on its merits in the
    order denying the motion for reconsideration. See PFS Distrib. Co. v.
    Raduechel, 
    574 F.3d 580
    , 598 (8th Cir. 2009).
    12
    Wong also challenges the district court’s denial of his motion for
    leave to amend. In light of our reversal of the dismissal of Wong’s
    complaint, we need not decide whether the district court abused its
    discretion by denying Wong’s motion. But we note that district courts
    should apply Rule 15(a) liberally, particularly when no answer has been
    filed, as was the case here. See Schreiber Distrib. Co. v. Serv-Well
    Furniture Co., 
    806 F.2d 1393
    , 1401 (9th Cir. 1986) (“[L]eave to amend
    should be granted unless the court determines that the allegation of other
    facts consistent with the challenged pleading could not possibly cure the
    deficiency.”).
