    Opinion by Judge Milan D. Smith, Jr.
    SUMMARY *
    Employee Retirement Income Security Act
    On remand from the Supreme Court, the en banc court
    vacated the district court’s judgment in favor of an employer
    and its benefits plan administrator on claims of breach of
    fiduciary duty in the selection and retention of certain mutual
    funds for a benefit plan governed by ERISA.
    The court of appeals had previously affirmed the district
    court’s holding that the plan beneficiaries’ claims regarding
    the selection of mutual funds in 1999 were time-barred under
    the six-year limit of 29 U.S.C. § 1113(1). The Supreme
    *
    This summary constitutes no part of the opinion of the court. It
    has been prepared by court staff for the convenience of the reader.
    4            TIBBLE V. EDISON INTERNATIONAL
    Court vacated the court of appeals’ decision, observing that
    federal law imposes on fiduciaries an ongoing duty to
    monitor investments even absent a change in circumstances.
    Rejecting defendants’ contention that the beneficiaries
    waived the ongoing-duty-to-monitor argument, the en banc
    court held that the beneficiaries did not forfeit the argument
    either in the district court or on appeal. Rather, defendants
    themselves failed to raise the waiver argument in their initial
    appeal, and thus forfeited this argument.
    The en banc court distinguished Phillips v. Alaska Hotel
    & Rest. Emps. Pension Fund, 
    944 F.2d 509
    (9th Cir. 1991),
    which held that when a fiduciary violated a continuing duty
    over time, the three-year limitations period set forth in 29
    U.S.C. § 1113(2) began when the plaintiff had actual
    knowledge of a breach in a series of discrete but related
    breaches. The panel held that Phillips did not apply to the
    continuing duty claims at issue under § 1113(1). Thus, only
    a “breach or violation,” such as a fiduciary’s failure to
    conduct its regular review of plan investments, need occur
    within the six-year statutory period of § 1113(1); the initial
    investment need not be made within the statutory period.
    Looking to the law of trusts to determine the scope of
    defendants’ fiduciary duty to monitor investments, the en
    banc court held that the duty of prudence required
    defendants to reevaluate investments periodically and to take
    into account their power to obtain favorable investment
    products, particularly when those products were
    substantially identical—other than their lower cost—to
    products they had already selected.
    The en banc court vacated the district court’s decisions
    concerning the funds added to the ERISA plan before 2001
    and remanded on an open record for trial on the claim that,
    TIBBLE V. EDISON INTERNATIONAL                  5
    regardless of whether there was a significant change in
    circumstances, defendants should have switched from retail-
    class fund shares to institutional-class fund shares to fulfill
    their continuing duty to monitor the appropriateness of the
    trust investments. The en banc court also directed the district
    court to reevaluate its award of costs and attorneys’ fees in
    light of the Supreme Court’s decision and the en banc court’s
    decision.

    OPINION
    M. SMITH, Circuit Judge:
    FACTS AND PRIOR PROCEEDINGS
    Edison sponsors a defined-contribution 401(k) Savings
    Plan (Plan), wherein “participants’ retirement benefits are
    limited to the value of their own individual investment
    accounts, which is determined by the market performance of
    employee and employer contributions, less expenses.”
    Tibble v. Edison Int’l, 
    135 S. Ct. 1823
    , 1826 (2015) (Tibble
    IV). “Expenses, such as management or administrative fees,
    can sometimes significantly reduce the value of an account
    in a defined-contribution plan.” 
    Id. In 2007,
    plaintiffs-appellants (beneficiaries) brought this
    action against Edison and the other defendants (collectively,
    Edison). The district court denied the beneficiaries’ motion
    for partial summary judgment, and partially granted
    Edison’s summary judgment motion. Tibble v. Edison Int’l,
    
    639 F. Supp. 2d 1074
    , 1080 (C.D. Cal. 2009) (Tibble I). This
    appeal concerns a claim that survived summary judgment;
    namely, that Edison breached its fiduciary duties by offering
    “higher priced retail-class mutual funds as Plan investments
    when materially identical lower priced institutional-class
    TIBBLE V. EDISON INTERNATIONAL                    7
    mutual funds were available (the lower price reflects lower
    administrative costs).” Tibble 
    IV, 135 S. Ct. at 1826
    .
    The Plan is governed by the Employee Retirement
    Income Security Act (ERISA), 29 U.S.C. §§ 1001–1461.
    The relevant ERISA statute of limitations is six years,
    29 U.S.C. § 1113(1), and at least three of the disputed funds
    were added more than six years before the complaint was
    filed. Tibble 
    IV, 135 S. Ct. at 1826
    . The district court
    allowed the beneficiaries to present evidence that their
    claims concerning those funds were timely because Edison,
    within the six-year limitations period, “fail[ed] to convert the
    retail shares to institutional shares upon the occurrence of
    certain ‘triggering events’” that should have prompted a full
    due-diligence review. Tibble v. Edison Int’l, No. CV 07-
    5359 SVW (AGRx), 
    2010 U.S. Dist. LEXIS 69119
    , at *99
    (C.D. Cal. July 8, 2010) (Tibble II).
    After a bench trial, the district court ruled for the
    beneficiaries on the retail-class funds selected within the six-
    year period, because Edison did “not offer[] any credible
    explanation for why the retail share classes were selected
    instead of the institutional share classes,” and “a prudent
    fiduciary acting in a like capacity would have invested in the
    institutional share classes.” 
    Id. at *98.
    Indeed, the court held
    that there was “no evidence that [Edison] even considered or
    evaluated the different share classes” when the funds were
    added. 
    Id. at *81
    (emphasis in original).
    As to the funds initially selected before the statute of
    limitations, the district court held that the “triggering events”
    proffered by the beneficiaries for two of the funds—a name
    change because of a partial change in ownership of a sub-
    advisor, and a name change related to a years-old ownership
    change—were insufficient to trigger a full diligence review,
    and that a change in strategy in a third fund—from small-cap
    8            TIBBLE V. EDISON INTERNATIONAL
    to mid-cap—triggered a review to which Edison responded
    adequately by adding another small-cap option. 
    Id. at *102–
    07.
    On appeal to our court, the beneficiaries argued that the
    district court should have allowed them to prove their claims
    concerning funds selected before the relevant six-year
    period. Tibble v. Edison Int’l, 
    729 F.3d 1110
    , 1119 (9th Cir.
    2013) (Tibble III), vacated, 
    135 S. Ct. 1823
    , 1829 (2015). In
    response, Edison acknowledged that it had a duty to monitor
    the funds for changed circumstances that would make the
    investment no longer prudent, but argued that the
    beneficiaries did not show sufficiently changed
    circumstances. Our vacated decision accepted Edison’s
    contention, and noted that “the district court was entirely
    correct to have entertained” the possibility of changed
    circumstances, and correct to have found the circumstances
    insufficient to trigger a response by Edison. 
    Id. at 1120.
    We
    thus concluded that any theory of a duty absent changed
    circumstances amounted to a continuing violation theory
    that we declined to read into the ERISA statute of
    limitations. 
    Id. at 1119–20.
    Plaintiffs successfully petitioned for certiorari, and the
    Supreme Court reversed our decision concerning the statute
    of limitations, holding that regardless of when an investment
    was initially selected, “a fiduciary’s allegedly imprudent
    retention of an investment” is an event that triggers a new
    statute of limitations period. Tibble 
    IV, 135 S. Ct. at 1826
    ,
    1828–29. The Court specifically rejected “the conclusion
    that only a significant change in circumstances could
    engender a new breach of a fiduciary duty.” 
    Id. at 1827.
    We
    were cautioned against “applying a statutory bar to a claim
    of a ‘breach or violation’ of a fiduciary duty without
    considering the nature of the fiduciary duty,” and told to
    TIBBLE V. EDISON INTERNATIONAL                 9
    “recognize that under trust law a fiduciary is required to
    conduct a regular review of its investment with the nature
    and timing of the review contingent on the circumstances.”
    
    Id. at 1827–28.
    The Court instructed us to decide “the scope
    of [Edison’s] fiduciary duty” to monitor investments. 
    Id. at 1829.
    The Court also left to us on remand “any questions of
    forfeiture,” acknowledging Edison’s contention that the
    beneficiaries “did not raise the claim below that [Edison]
    committed new breaches of the duty of prudence by failing
    to monitor their investments and remove imprudent ones
    absent a significant change in circumstances.” 
    Id. A panel
    of our court in Tibble v. Edison International,
    
    820 F.3d 1041
    , 1048 (9th Cir. 2016) (Tibble V), concluded
    that the issue was forfeited. We then ordered that the case
    be reheard en banc, so the panel’s decision in Tibble V is
    vacated. Tibble v. Edison Int’l, 
    831 F.3d 1262
    (9th Cir.
    2016).
    For the reasons discussed below, we vacate the district
    court’s decisions concerning the funds added to the Plan
    before 2001, and remand for trial on an open record on the
    claim that, regardless of whether there was a significant
    change in circumstances, Edison should have switched from
    retail-class fund shares to institutional-class fund shares to
    fulfill its continuing duty to monitor the appropriateness of
    the trust investments. We also encourage the district court
    to reevaluate its fee determination in light of the Supreme
    Court’s decision, and our decision en banc.

    JURISDICTION AND STANDARD OF REVIEW
    We have jurisdiction pursuant to 28 U.S.C. § 1291. We
    review summary judgment determinations de novo. Szajer
    v. City of Los Angeles, 
    632 F.3d 607
    , 610 (9th Cir. 2011).
    ANALYSIS
    I. Applicable Law
    The applicable statute of limitations in this case is the
    six-year limit of 29 U.S.C. § 1113(1)(A), which states that
    “[n]o action may be commenced . . . with respect to a
    fiduciary’s breach of any responsibility, duty, or obligation
    . . . six years after [] the date of the last action which
    constituted a part of the breach or violation.” As the
    Supreme Court noted in Tibble IV, under this statute only a
    “breach or violation,” not an original investment decision,
    need occur to start the six-year statutory 
    period. 135 S. Ct. at 1827
    .
    Generally, we do not “entertain[] arguments on appeal
    that were not presented or developed before the district
    court.” Visendi v. Bank of Am., N.A., 
    733 F.3d 863
    , 869 (9th
    Cir. 2013). “Although no bright line rule exists to determine
    whether a matter [h]as been properly raised below, an issue
    will generally be deemed waived on appeal if the argument
    was not raised sufficiently for the trial court to rule on it.” In
    re Mercury Interactive Corp. Sec. Litig., 
    618 F.3d 988
    , 992
    (9th Cir. 2010) (internal quotation marks omitted).
    II. Forfeiture
    Before addressing the statute of limitations and ERISA-
    trust law issues remanded to us by the Supreme Court, we
    address Edison’s claims that the issues presently on appeal
    TIBBLE V. EDISON INTERNATIONAL                           11
    have been forfeited by the beneficiaries. We conclude that
    the beneficiaries did not forfeit their failure-to-monitor
    argument in either the district court or on appeal. Instead,
    we conclude that Edison itself forfeited the forfeiture
    argument in its initial appeal.
    A. There Was No Forfeiture by the Beneficiaries on
    Appeal
    We begin with the appeal. The beneficiaries argued in
    their opening brief that:
    Defendants had a continuing duty to ensure
    that each of the Plans’ investment options
    was and remained prudent and had
    reasonable expenses. Merely because they
    allowed an imprudent fund into the Plan at
    one point does not mean Defendants could
    just leave it in the Plan forever. Within six
    years prior to the commencement of this
    action, Defendants could have switched the
    Plan out of the retail shares and into the
    institutional shares of three excluded mutual
    funds and saved the Plan millions in
    unnecessary fees. 1
    1
    Edison attempts to obscure this clear statement with irrelevant
    specificity, noting that “Plaintiffs’ appellate briefs also did not raise the
    argument . . . that the district court’s summary judgment orders
    improperly barred plaintiffs from challenging Edison’s monitoring of the
    pre-2001 mutual funds during the repose period, unless plaintiffs
    established that the funds underwent significant changes.” But, having
    lost at trial on the merits of the “significant changes” issue, the
    beneficiaries argued simply that the district court should have allowed a
    claim that “‘the last action which constituted a part of the breach’—using
    12             TIBBLE V. EDISON INTERNATIONAL
    Similarly, the beneficiaries argued:
    At any time in that six-year period
    Defendants could have switched from retail
    to institutional class shares. Their failure to
    do so caused the Plan to pay unnecessary,
    retail fees in each of those six years.
    Therefore, the “last action which constituted
    a part of the breach”—using retail class
    shares—occurred within six years and the
    “latest date on which the fiduciary could have
    cured the breach”—replacing retail with
    institutional shares—also occurred within six
    years.
    And, the beneficiaries argued that “[f]und fiduciaries . . .
    were under a continuing obligation to advise the Fund to
    divest itself of unlawful or imprudent investments.” (Citing
    Buccino v. Cont’l Assurance Co., 
    578 F. Supp. 1518
    , 1521
    (S.D.N.Y. 1983)).
    Thus, the beneficiaries argued on appeal for an ongoing
    duty to monitor investments and to remove imprudent
    investments—a duty that was not limited to “changed
    circumstances.” The theory was simply that: “[i]n light of
    the continuing duty of prudence imposed on plan fiduciaries
    by ERISA, each failure to exercise prudence constitutes a
    new breach of duty, that is to say, a new claim”—squarely
    embracing the theory accepted by the Supreme Court. See
    retail class shares—occurred within six years.” That the beneficiaries’
    later phrasing articulated both what the district court allowed (a
    significant changes theory) and what the district court rejected (a pure
    continuing duty to prudently monitor) does not show forfeiture of the
    latter argument. Indeed, it was specifically raised in the beneficiaries’
    opening brief.
    TIBBLE V. EDISON INTERNATIONAL                  13
    Tibble 
    IV, 135 S. Ct. at 1829
    . In response, Edison argued for
    a duty that was limited to changed circumstances: “Plan
    fiduciaries do have a continuing duty under ERISA to
    monitor investment options for changed circumstances
    rendering a once-prudent investment now imprudent, but
    plaintiffs here allege no changed circumstances.” The
    Tibble III panel accepted Edison’s limiting theory, but the
    Supreme Court rejected it. The claim was not forfeited on
    appeal.
    B. There Was No Forfeiture by the Beneficiaries in
    the District Court
    Nor did the beneficiaries forfeit their claim in the district
    court. Edison’s post-trial briefing stated:
    The Court expressly held in its first summary
    judgment ruling that plaintiffs could not
    revisit the prudence of selecting mutual funds
    that became part of the Plan’s investment
    lineup more than six years prior to the filing
    of the Complaint. By challenging the
    prudence of maintaining retail share classes
    of the three “name change” funds, plaintiffs
    have done what the Court has forbidden, by
    attempting to resurrect claims that were
    properly held barred by the six-year statute of
    limitations.
    (Emphasis added and citation omitted).           Given this
    contemporaneous statement that any claim challenging the
    prudence of maintaining retail share classes first selected
    before the limitations period had been rejected on summary
    judgment, it is hard to see how Edison can now argue that
    the beneficiaries forfeited the argument by not presenting
    “any evidence establishing that a prudent fiduciary would
    14           TIBBLE V. EDISON INTERNATIONAL
    have identified the alleged share-class issue during regular,
    periodic reviews.”
    Simply put, the district court held at summary judgment
    that because “the initial decision to add retail mutual funds”
    was made outside of the six-year limitations period, “the
    prudence claims arising out of these decisions are barred by
    the statute of limitations.” Tibble 
    I, 639 F. Supp. 2d at 1120
    .
    And, the district court stated in its trial decision: “three
    funds were added to the Plan before the statute of limitations
    period; thus, Plaintiffs challenged the failure to switch to an
    institutional share class upon the occurrence of certain
    significant events within the limitations period.” Tibble II,
    
    2010 U.S. Dist. LEXIS 69119
    at *7 (emphasis added). The
    district court used the causal “thus” to describe why
    Plaintiffs relied on a “significant changes theory”: because
    prudence claims arising out of the initial selection were
    outside the statute of limitations, and barred by the summary
    judgment order (absent changed circumstances).
    Edison also pointed to the district court’s questioning of
    the beneficiaries’ expert, Dr. Steven Pomerantz, who
    attempted to identify changed circumstances that would
    have triggered a duty to switch the share class, such that the
    claim would not be barred by the district court’s statute of
    limitations ruling. In conversation with Pomerantz, the
    district court said that it did not understand the connection
    between a name change of a fund and whether Edison should
    have switched to institutional class shares, and asked
    whether Edison should have removed the funds even without
    a name change. The court asked: “[w]ould you contend . . .
    that during the relevant time period due diligence would
    have required the plan to nevertheless buy an institutional
    share class, all things being equal, assuming the institutional
    share class had a lower fee?” Pomerantz mostly stuck to his
    TIBBLE V. EDISON INTERNATIONAL                    15
    significant changes theory in response. Edison argued that
    this exchange showed that the district court did not forbid a
    duty-to-monitor claim; indeed, according to Edison, the
    district court “invited Pomerantz to make [a duty-to-monitor
    claim] . . . , but he refused to agree,” sticking to the
    significant changes theory.
    It is certainly possible that the district court had forgotten
    a portion of its voluminous summary judgment ruling, and
    was at that time open to a theory imposing a continuing duty
    in the absence of “changed circumstances.” Or it could be,
    as the beneficiaries suggest, that the district court was
    checking to see whether the theory Pomerantz was
    articulating was in substance the same as the theory the
    district court had excluded. It does not matter which
    interpretation is correct, because neither shows forfeiture.
    Whatever the intent behind the district court’s hypothetical
    questions to an expert, they did not constitute a change in its
    earlier ruling sufficient to put the beneficiaries on notice that
    they could then, contrary to the court’s earlier ruling, put on
    evidence to prove their preferred continuing duty theory.
    Finally, Edison emphasizes that the district court
    allowed the beneficiaries to put on a continuing duty case
    concerning a different investment, the Money Market Fund.
    See Tibble II, 
    2010 U.S. Dist. LEXIS 69119
    at *108–21. It
    is true that the claims have much in common, and it is not
    clear why the district court provided a distinct treatment of
    the Money Market Fund. Perhaps it was because Edison
    continued to negotiate the rate for the fund throughout the
    period at issue, while Edison employed a “set it and forget
    it” approach with the mutual funds. Whatever the reason,
    that the district court allowed a similar claim as to the Money
    Market Fund simply does not show that, contrary to both
    sides’ understanding, the beneficiaries were allowed to put
    16           TIBBLE V. EDISON INTERNATIONAL
    on a monitor-and-remove-absent-significant-changed-
    circumstances theory concerning the mutual funds.
    Because the beneficiaries—and Edison—reasonably
    believed that the district court’s summary judgment order
    precluded the duty to monitor claim, and because the
    beneficiaries preserved the claim on appeal, it has not been
    forfeited.
    C. Edison’s Own Forfeiture
    The beneficiaries argue that Edison forfeited its
    forfeiture argument by failing to raise it in the initial appeal.
    Edison did not argue forfeiture in the initial appeal consistent
    with its understanding, as expressed in its post-trial motion,
    that the district court’s summary judgment ruling barred
    claims relating to the funds first selected before 2001.
    Edison argues that it did not raise forfeiture because the
    beneficiaries did not articulate their continuing duty theory
    before they submitted their Supreme Court briefing.
    However, as discussed above, the beneficiaries raised the
    continuing duty argument in their opening brief on appeal.
    Edison therefore forfeited any potential forfeiture response
    to that argument. And, even at the Supreme Court, where
    the beneficiaries clearly presented their continuing duty
    argument in their petition for certiorari, Edison responded
    not that the beneficiaries had forfeited that claim, but
    instead, that a fiduciary only has a “duty to monitor for
    material changes in circumstances.” (Emphasis omitted).
    III. Phillips Does Not Bar the Beneficiaries’ Claim
    In Phillips v. Alaska Hotel and Restaurant Employees
    Pension Fund, 
    944 F.2d 509
    , 520–21 (9th Cir. 1991), we
    held that the limitations period under a different subsection
    TIBBLE V. EDISON INTERNATIONAL                         17
    of the ERISA statute of limitations, 29 U.S.C. § 1113(2),
    begins when a plaintiff has actual knowledge of a breach.
    When there is “a series of discrete but related breaches”
    because a fiduciary violated a continuing duty over time, the
    § 1113(2) limitations period does not begin anew with each
    related breach. 
    Id. Phillips followed
    the plain language of the statute:
    § 1113(2) provides that the plaintiff’s “actual knowledge of
    the breach” is measured from “three years after the earliest
    date” of such knowledge. “Once a plaintiff knew of one
    breach, an awareness of later breaches [of the same
    character] would impart nothing materially new,” and
    applying a “continuing violation theory [would] essentially
    read[] the ‘actual knowledge’ standard out of [§ 1113(2)].”
    
    Phillips, 944 F.2d at 520
    . Thus, we held that “[t]he earliest
    date on which a plaintiff became aware of any breach . . .
    start[s] the limitation period of § 1113[](2) 2 running.” 
    Id. The district
    court in Tibble I misunderstood Phillips to
    stand for the broad proposition that “[t]here is no ‘continuing
    violation’ theory to claims subject to ERISA’s statute of
    limitations.” Tibble 
    I, 639 F. Supp. 2d at 1086
    . However,
    Phillips did not reject a continuing violation theory for the
    ERISA statute of limitations generally; it merely held that,
    for claims subject to § 1113(2), the earliest date of actual
    knowledge of a breach begins the limitations period, even if
    the breach continues. When a plaintiff has actual knowledge
    of a breach, § 1113(2) operates to keep her from sitting on
    her rights and allowing the series of related breaches to
    2
    Our opinion identified the statute as § 1113(a)(2), but quoted from
    and discussed § 1113(2). Because there is no subsection (a)(2) in § 1113,
    the reference appears to have been in error, and Phillips’ holding applies
    to § 1113(2).
    18             TIBBLE V. EDISON INTERNATIONAL
    continue. However, when a plaintiff does not have actual
    knowledge of a breach of a continuing duty and § 1113(1)
    applies, the rationale for Phillips’ continuing duty limit on
    § 1113(2) is no longer relevant. Thus, we hold that Phillips
    is inapplicable to the continuing duty claims at issue here,
    namely to 29 U.S.C. § 1113(1). 3
    The Supreme Court held that the fiduciary duty
    identified in this case is continuing in nature, and that each
    new breach begins a six-year limitations period under
    § 1113(1).     The Court recognized the breach as “a
    fiduciary’s allegedly imprudent retention of an investment”
    which results in a series of related breaches as the investment
    is retained over time. Tibble 
    IV, 135 S. Ct. at 1826
    , 1828–
    29 (emphasis added). As the Court made clear, only a
    “breach or violation,” such as a fiduciary’s failure to conduct
    its required regular review of Plan investments, need occur
    within the six-year statutory period; the initial investment
    need not be made within the statutory period. 
    Id. at 1827–
    28.
    IV. ERISA and Analogous Trust Law
    The Supreme Court tasked us with resolving “the scope
    of [Edison’s] fiduciary duty” to monitor investments, while
    3
    The district court held that the beneficiaries’ claims were governed
    by § 1113(1) because Edison did not produce undisputed evidence of the
    beneficiaries’ actual knowledge of the alleged breaches, making
    § 1113(2) inapplicable. Tibble 
    I, 639 F. Supp. 2d at 1086
    . We affirmed,
    holding that, “because the[] beneficiaries’ trial claims hinged on
    infirmities in the selection process for investments,” Edison’s contention
    that “mere notification that retail funds were in the Plan menu” was
    insufficient to satisfy the “actual knowledge” standard. Tibble 
    III, 729 F.3d at 1121
    . The Supreme Court also applied § 1113(1). Tibble
    
    IV, 135 S. Ct. at 1827
    .
    TIBBLE V. EDISON INTERNATIONAL                  19
    “recognizing the importance of analogous trust law.” 
    Id. at 1829.
    Edison’s fiduciary duty arises from ERISA, “a
    comprehensive statute designed to promote the interests of
    employees and their beneficiaries in employee benefit
    plans.” Shaw v. Delta Air Lines, Inc., 
    463 U.S. 85
    , 90
    (1983).     “An ERISA fiduciary must discharge his
    responsibility ‘with the care, skill, prudence, and diligence’
    that a prudent person ‘acting in a like capacity and familiar
    with such matters’ would use.” Tibble 
    IV, 135 S. Ct. at 1828
    (quoting 29 U.S.C. § 1104(a)(1)). “These duties are the
    highest known to the law.” Howard v. Shay, 
    100 F.3d 1484
    ,
    1488 (9th Cir. 1996) (internal quotation marks omitted). “To
    enforce them, the court focuses not only on the merits of the
    transaction, but also on the thoroughness of the investigation
    into the merits of the transaction.” 
    Id. ERISA fiduciary
    duties are derived from the common
    law of trusts, so “courts often must look to the law of trusts”
    to “determin[e] the contours of an ERISA fiduciary’s duty.”
    Tibble 
    IV, 135 S. Ct. at 1828
    . “Under trust law, a trustee has
    a continuing duty to monitor trust investments and remove
    imprudent ones . . . separate and apart from the trustee’s duty
    to exercise prudence in selecting investments at the outset.”
    
    Id. “[A] trustee
    cannot assume that if investments are legal
    and proper for retention at the beginning of the trust, or when
    purchased, they will remain so indefinitely.” 
    Id. (quoting A.
    HESS, G. BOGERT & G. BOGERT, LAW OF TRUSTS AND
    TRUSTEES § 684, 145–46 (3d ed. 2009) [hereinafter Bogert
    3d]). “Rather, the trustee must ‘systematic[ally] conside[r]
    all the investments of the trust at regular intervals’ to ensure
    that they are appropriate.” 
    Id. (quoting Bogert
    3d § 684, at
    147–48). In fulfilling his duties, a trustee is held to “the
    prudent investor rule,” which requires that he “invest and
    manage trust assets as a prudent investor would”; that is, by
    “exercis[ing] reasonable care, skill, and caution,” and by
    20            TIBBLE V. EDISON INTERNATIONAL
    “reevaluat[ing] the trust’s investments periodically as
    conditions change.” Bogert 3d § 684.
    Additionally, pursuant to the Restatement (Third) of
    Trusts, a trustee is to “incur only costs that are reasonable in
    amount and appropriate to the investment responsibilities of
    the trusteeship.”       RESTATEMENT (THIRD) OF TRUSTS
    § 90(c)(3); see also 
    id. § 88.
    The Restatement further
    instructs that “cost-conscious management is fundamental to
    prudence in the investment function,” and should be applied
    “not only in making investments but also in monitoring and
    reviewing investments.” 
    Id. § 90,
    cmt. b; see also 
    id. § 88,
    cmt. a (“Implicit in a trustee’s fiduciary duties is a duty to be
    cost-conscious.”); Donahue v. Donahue, 
    182 Cal. App. 4th 259
    , 273 (2010) (reversing and remanding an award for
    attorneys’ fees incurred by a trustee because the trial court
    did not consider whether the trustee fulfilled his duty to be
    cost-conscious in incurring the fees). As the Uniform
    Prudent Investor Act observes: “Wasting beneficiaries’
    money is imprudent. In devising and implementing
    strategies for the investment and management of trust assets,
    trustees are obliged to minimize costs.” Unif. Prudent
    Investor Act § 7.
    It is beyond dispute that the higher the fees charged to a
    beneficiary, the more the beneficiary’s investment shrinks.
    As a simple example, if a beneficiary invested $10,000, the
    investment grew at a rate of 7% a year for 40 years, and the
    fund charged 1% in fees each year, 4 at the end of the 40-year
    period the beneficiary’s investment would be worth
    4
    The funds Edison offered beneficiaries had expense ratios ranging
    from 0.03% to 2%. Tibble 
    I, 639 F. Supp. 2d at 1117
    .
    TIBBLE V. EDISON INTERNATIONAL                           21
    $100,175. If the fees were raised to 1.18%, or 1.4%, 5 the
    value of the investment at the end of the 40-year period
    would decrease to $93,142 and $85,198, respectively.
    Beneficiaries subject to higher fees for materially identical
    funds lose not only the money spent on higher fees, but also
    “lost investment opportunity”; that is, the money that the
    portion of their investment spent on unnecessary fees would
    have earned over time. Tibble II, 
    2010 U.S. Dist. LEXIS 69119
    , at *124–25. Pursuant to the aforementioned trust law
    principles, a trustee cannot ignore the power the trust wields
    to obtain favorable investment products, particularly when
    those products are substantially identical—other than their
    lower cost—to products the trustee has already selected.
    The beneficiaries request “a new trial on the issue of
    whether [Edison] breached [its] fiduciary duties by
    providing as Plan investments during the limitations period
    mutual funds in a share class that was more expensive than
    other share classes that were available to the Plan.” (Citing
    Lam v. Univ. Of Haw., 
    40 F.3d 1551
    , 1554–55, 1566–67 (9th
    Cir. 1994) (remanding for trial after reversal of summary
    judgment)). The beneficiaries wrote that “[b]ecause [they]
    were precluded from presenting [the continuing-duty-
    absent-changed-circumstances] claims by the district court’s
    erroneous interpretation of the limitations statute, there is no
    record on which the Court can resolve this claim on appeal.”
    We agree that the record does not establish exactly what
    would have resulted from the application of the correct legal
    standard, and accordingly remand on an open record for the
    5
    The district court found that, for Edison’s six retail class funds that
    had institutional class funds available, each retail fund’s fees were 0.18%
    to 0.4% higher than the corresponding institutional funds’ fees over the
    2001–2009 period. Tibble II, 
    2010 U.S. Dist. LEXIS 69119
    , at *26–41.
    22           TIBBLE V. EDISON INTERNATIONAL
    district court to consider these issues in light of the principles
    explicated by the Supreme Court and this opinion.
    V. Attorneys’ Fees and Costs
    The beneficiaries also requested that we direct the
    district court “to reconsider an award of costs and attorney
    fees in light of the results of the trial on remand.” The
    beneficiaries had originally sought nearly $2.5 million in
    attorneys’ fees and nontaxable costs, and in response to the
    court’s order, sought a reduced amount of $407,277.30 in
    fees and $3,731.92 in costs. The district court held that even
    if the attorneys’ fees request was appropriate, it would be
    offset by the costs due to Edison as the prevailing party on
    the majority of claims originally filed.
    In determining that the beneficiaries’ original fee request
    should be drastically reduced, the district court expressed its
    skepticism concerning the importance of the beneficiaries’
    partial victory. Considering the Supreme Court decision that
    followed, and our en banc decision in this case, we believe
    that this case has far greater importance than the district
    court believed it did at the time of its earlier fee
    determinations. Accordingly, we direct the district court to
    reconsider the fee issue in light of the significant amount of
    work that has been required to vindicate an important ERISA
    principle in our court and the Supreme Court.
    CONCLUSION
    We VACATE the district court’s decisions concerning
    the funds added to the Plan before 2001, and REMAND on
    an open record for trial on the claim that, regardless of
    whether there was a significant change in circumstances,
    Edison should have switched from retail-class fund shares to
    institutional-class fund shares to fulfill its continuing duty to
    TIBBLE V. EDISON INTERNATIONAL             23
    monitor the appropriateness of the trust investments. The
    district court is also directed to reevaluate its fee
    determination in light of the Supreme Court’s decision and
    this court’s en banc decision.
