    SUMMARY **
    Multiemployer Pension Plan Amendments Act
    The panel affirmed in part and vacated in part the district court’s order affirming,
    except for a typographical error, an arbitrator’s award regarding the withdrawal
    liability, under the Multiemployer Pension Plan Amendments Act of 1980, of MNG
    Enterprises, following MNG’s complete withdrawal from GCIU-Employer
    Retirement Fund, a multiemployer pension plan.
    GCIU’s actuary calculated MNG’s withdrawal liability using an interest rate
    published by the Pension Benefit Guaranty Corporation (PBGC). The actuary also
    accounted for the contribution histories of two newspapers that MNG had acquired
    several years before its complete withdrawal. On MNG’s challenge, the arbitrator
    found (1) that MNG could not be assessed partial withdrawal liability following a
    complete withdrawal, (2) that it had shown the interest rate used was not the best
    estimate of the plan’s experience, and (3) that GCIU properly considered the
    newspapers’ contribution histories because MNG was a successor to them.
    Under the MPPAA, withdrawal liability covers the employer’s proportionate
    share of the plan’s unfunded vested benefits, calculated as the difference between
    the present value of the vested benefits and the current value of the plan’s
    assets. When an employer sells its assets and withdraws from the pension plan, it
    ordinarily incurs liability for a complete withdrawal. The obligation to pay that
    liability usually remains with the selling employer, but courts have equitable
    discretion to hold the purchaser responsible. If a dispute arises as to the amount of
    withdrawal liability, arbitration is required.
    MNG included two smaller controlled groups, MediaNews Group and California
    Newspaper Partnership Controlled Group. In 2013, California Newspaper
    completely withdrew from GCIU. In 2014, MediaNews did the same, ending
    MNG’s contributions to GCIU. In 2018, GCIU assessed against MediaNews a 2014
    complete withdrawal and two subsequent partial withdrawals for 2014 and 2015. In
    2006 and 2007, MediaNews and California Newspaper had acquired the assets of

    two newspapers, the Torrance Daily Breeze and the Santa Cruz Sentinel, which had
    participated in GCIU but stopped contributing before MNG acquired them. Nothing
    in the record suggested that GCIU assessed withdrawal liability against the
    newspapers when they withdrew.
    Affirming in part, the panel held that, under the unambiguous text of the MPPAA,
    a partial withdrawal cannot occur after a complete withdrawal when the employer
    has not otherwise resumed operations or contributions. Thus, GCIU could not assess
    MNG for two partial withdrawals following its complete withdrawal.
    The panel held that the MPPAA directs the plan actuary to determine withdrawal
    liability based on “actuarial assumptions and methods which, in the aggregate, are
    reasonable (taking into account the experience of the plan and reasonable
    expectations) and which, in combination, offer the actuary’s best estimate of
    anticipated experience under the plan.” The panel held that the GCIU actuary’s use
    of the PBGC rate, without considering the “experience of the plan and reasonable
    expectations,” did not satisfy the “best estimate” standard.
    Vacating in part as to the inclusion of the newspapers’ contribution histories, the
    panel held that if a purchaser is a successor and has notice of the withdrawal liability,
    then a court may use its equitable discretion to hold the purchaser liable. The district
    court concluded that MediaNews and California Newspaper were successors to the
    Daily Breeze and the Sentinel and that both had notice of the potential liability. The
    panel held that the district court abused its discretion by not considering MNG’s
    possible successor liability as of the asset sale dates in 2006 and 2007. The panel
    vacated and remanded for the district court to determine in the first instance whether
    MNG had successor liability and if GCIU correctly applied the newspapers’
    contribution histories at the time of the asset sales.

    R. NELSON, Circuit Judge:
    The Multiemployer Pension Plan Amendments Act of 1980 imposes liability
    on employers who withdraw—partially or completely—from multiemployer
    pension funds. That liability assessment is based on “the actuary’s best estimate of
    anticipated experience under the plan.” 
    29 U.S.C. § 1393
    (a)(1). After a complete
    withdrawal, GCIU-Employer Retirement Fund’s (GCIU) actuary calculated MNG
    Enterprise’s (MNG) withdrawal liability using an interest rate published by the
    Pension Benefit Guaranty Corporation.          The actuary also accounted for the
    contribution histories of two newspapers that MNG had acquired several years
    before its complete withdrawal.
    On MNG’s challenge, an arbitrator found (1) that MNG could not be assessed
    partial withdrawal liability following a complete withdrawal, (2) that it had shown
    the interest rate used was not the best estimate of the plan’s experience, and (3) that
    GCIU properly included the newspapers’ contribution histories. The district court
    affirmed the arbitrator’s award, vacating and correcting only a typographical error
    on the interest rate. We partially affirm, partially vacate, and remand for the district
    court to decide whether successor liability would apply to MNG at the time of the
    asset sales.

    I
    A
    Congress enacted the Employee Retirement Income Security Act of 1974
    (ERISA) to ensure that pensions maintain sufficient funding to pay pensioners’
    benefits. 
    29 U.S.C. § 1001
    (a). ERISA’s minimum funding standards require
    employers to contribute enough assets to pension plans to cover future liabilities.
    See 
    26 U.S.C. § 412
    (a). ERISA also provides for withdrawal liability. See 
    29 U.S.C. § 1364
    . Under the old rules, that liability did not kick in until the plan became
    insolvent—once it was insolvent, ERISA imposed liability on “any employer who
    had withdrawn from the plan during the previous five years” for their “fair share of
    the plan’s underfunding.” Milwaukee Brewery Workers’ Pension Plan v. Joseph
    Schlitz Brewing Co., 
    513 U.S. 414
    , 416 (1995).
    Before the Multiemployer Pension Plan Amendments Act of 1980 (MPPAA),
    multiemployer pension plans faced special problems. For instance, employers
    participating in a multiemployer plan could withdraw without triggering the liability
    provisions. See United Mine Workers of Am. 1974 Pension Plan v. Energy W.
    Mining Co., 
    39 F.4th 730
    , 734 (D.C. Cir. 2022). As employers withdrew, the fund’s
    assets shrank; in turn, the remaining employers had to contribute more to meet the
    minimum funding standards. 
    Id.
     at 734–35. This created a vicious cycle: as soon as
    a plan was at risk for underfunding, employers would withdraw and risk the
    2
    possibility of later liability rather than take on the certainty of increased
    contributions in the meantime. Milwaukee Brewery, 
    513 U.S. at
    416–17.
    The MPPAA aimed to solve these problems by imposing withdrawal liability
    on employers when they withdrew from the plan rather than up to five years down
    the road. 
    29 U.S.C. § 1381
    (a). And that liability would cover “the employer’s
    proportionate share of the plan’s ‘unfunded vested benefits,’ calculated as the
    difference between the present value of the vested benefits and the current value of
    the plan’s assets.” Connolly v. Pension Benefit Guar. Corp., 
    475 U.S. 211
    , 217
    (1986); see also 
    29 U.S.C. §§ 1381
    (b), 1391. Both complete and partial withdrawals
    trigger withdrawal liability. See 
    29 U.S.C. § 1381
    (a), 1383, 1385.
    Pension plans now have rules explaining “how to determine a plan’s total
    underfunding” and “how to determine an employer’s fair share” of that
    underfunding. Milwaukee Brewery, 
    513 U.S. at
    417–18. The MPPAA gives the
    plan sponsor initial responsibility to determine an employer’s withdrawal liability.
    
    29 U.S.C. § 1382
    (1). The plan actuary must use “actuarial assumptions and methods
    which, in the aggregate, are reasonable (taking into account the experience of the
    plan and reasonable expectations) and which, in combination, offer the actuary’s
    best estimate of anticipated experience under the plan.”      § 1393(a)(1).   After
    determining the amount of liability, the plan must notify the employer “[a]s soon as
    practicable” and then collect the amount. §§ 1382(2)–(3), 1399(b)(1).
    3
    When an employer sells its assets and withdraws from the pension plan, it
    ordinarily incurs liability for a complete withdrawal. See §§ 1381(a), 1383(a),
    1384(a). The obligation to pay that liability usually remains with the selling
    employer. Heavenly Hana LLC v. Hotel Union & Hotel Indus. of Haw. Pension
    Plan, 
    891 F.3d 839
    , 842 (9th Cir. 2018). Under common law, courts have equitable
    discretion to hold the purchaser responsible for that liability. See Resilient Floor
    Covering Pension Tr. Fund Bd. of Trs. v. Michael’s Floor Covering, Inc., 
    801 F.3d 1079
    , 1084 (9th Cir. 2015). The common-law rule creating successor liability
    applies when the purchaser is (1) a successor and (2) has notice of the liability.
    Heavenly Hana, 891 F.3d at 843 (citation omitted). Even so, as “the origins of
    successor liability are equitable,” courts apply successor liability only “when it is
    fair to do so[.]” Id. at 847 (internal quotation marks omitted) (quoting Resilient
    Floor, 
    801 F.3d at 1091
    ).
    If a dispute arises as to the amount of withdrawal liability, ERISA and the
    MPPAA mandate arbitration. 
    29 U.S.C. § 1401
    (a). Any party may then appeal the
    arbitrator’s award to the proper United States district court. § 1401(b)(2).
    B
    MNG, the named party in this appeal, includes two smaller controlled groups,
    MediaNews Group and California Newspaper Partnership Controlled Group. In
    2013, California Newspaper completely withdrew from GCIU.                      In 2014,
    4
    MediaNews did the same, ending MNG’s contributions to GCIU. In 2018, GCIU
    assessed against MediaNews a 2014 complete withdrawal and two subsequent
    partial withdrawals for 2014 and 2015.1 The 2014 partial withdrawal liability totaled
    $8,650,737 and the 2015 partial withdrawal, $4,229,840.
    Previously in 2006, MediaNews acquired the assets of the Torrance Daily
    Breeze. Meanwhile, in 2007, California Newspaper acquired the assets of the Santa
    Cruz Sentinel. Both newspapers previously participated in GCIU and stopped
    contributing before MNG acquired them. Nothing in the record suggests that GCIU
    assessed withdrawal liability against the Daily Breeze or the Sentinel when they
    withdrew.
    In calculating MNG’s withdrawal liability, the plan actuary used the Pension
    Benefit Guaranty Corporation’s (PBGC) published rate, which was around 4%. The
    actuary testified that the PBGC rate is based on a settlement-type obligation and does
    not account for the future experience of the plan. Generally, using the PBGC rate
    results in a higher amount of withdrawal liability because it assumes a lower rate of
    growth. The actuary also included the contribution histories of the Daily Breeze and
    the Sentinel in calculating liability.
    MNG contested the 2014 and 2015 partial withdrawals, the use of the PBGC
    1
    GCIU also assessed partial withdrawal liability against MediaNews for 2012 and
    2013, but those withdrawals are not in dispute.
    5
    interest rate, and the inclusion of the newspapers’ contribution histories. The parties
    proceeded to arbitration.
    The arbitrator first found that MNG could not be liable for the partial
    withdrawals that occurred after it completely withdrew from GCIU. He reasoned
    that no partial withdrawals could occur following a complete withdrawal and that
    MNG had completely withdrawn by the reported dates of the partial withdrawals.
    Next, the arbitrator found that MNG had shown that the actuary relied on
    unreasonable assumptions in deciding the interest rate for the withdrawal liability
    because the PBGC rate disregarded the experience of the plan and the expected
    returns on assets. He instead directed GCIU to recalculate liability with a 7% interest
    rate. Finally, the arbitrator held that GCIU properly included the contribution
    histories of the newspapers acquired by MNG because MNG was a successor that
    had notice of the liabilities.
    Both parties sought judicial review. The district court affirmed the award,
    except with respect to the interest rate. Instead of the arbitrator’s 7% interest rate,
    the district court ordered an 8% interest rate because it believed the arbitrator made
    a typographical error. On appeal, GCIU contends that the district court erred in
    affirming the arbitrator’s award as to partial-withdrawal liability and the PBGC
    interest rate. MNG would have us affirm the district court on those issues but asks
    us to reverse the inclusion of the newspapers’ contribution histories.

    II
    Title 29, section 1401(b)(2) authorizes judicial review to “enforce, vacate, or
    modify the arbitrator’s award” in an MPPAA dispute. See Trs. of Amalgamated Ins.
    Fund v. Geltman Indus., Inc., 
    784 F.2d 926
    , 928 (9th Cir. 1986). We presume that
    “findings of fact made by the arbitrator were correct,” unless rebutted “by a clear
    preponderance of the evidence.” § 1401(c). We review conclusions of law de novo,
    Geltman Indus., 784 F.2d at 928–29, and applications of equitable relief for abuse
    of discretion, Metal Jeans, Inc. v. Metal Sport, Inc., 
    987 F.3d 1242
    , 1244 (9th Cir.
    2021). The standard of review for MPPAA arbitrations is notably less deferential
    than under the Federal Arbitration Act. See Bd. of Trs. of the W. States Off. & Pro.
    Emps. Pension Fund v. Welfare & Pension Admin. Serv., Inc., 
    24 F.4th 1278
    , 1283
    n.4 (9th Cir. 2022); Cent. States, Se. & Sw. Areas Pension Fund v. Nitehawk Exp.,
    Inc., 
    223 F.3d 483
    , 488 n.2 (7th Cir. 2000).
    III
    A
    The MPPAA defines two types of withdrawals, complete and partial. A
    complete withdrawal occurs when an employer “permanently ceases to have an
    obligation to contribute under the plan,” § 1383(a)(1), or when the employer
    “permanently ceases all covered operations under the plan,” § 1383(a)(2). A partial
    withdrawal occurs when there is “a 70-percent contribution decline” or “a partial
    7
    cessation of the employer’s contribution obligation.” § 1385(a). Section 1385 also
    specifies that a partial withdrawal will be treated as occurring “on the last day of a
    plan year.” Id. The MPPAA provides a formula for calculating the 70-percent
    contribution decline that depends on the employer’s contributions in the past 8 years.
    See § 1385(b)(1).
    MNG contends that a partial withdrawal cannot occur after a complete
    withdrawal. We agree.
    When interpreting statutes, the court “give[s] effect to the unambiguous words
    Congress actually used.” GCIU-Emp. Ret. Fund v. Quad/Graphics, Inc., 
    909 F.3d 1214
    , 1218 (9th Cir. 2018) (quotation omitted). Whether the language is plain
    depends on context and the overall statutory scheme. King v. Burwell, 
    576 U.S. 473
    ,
    486 (2015).
    As with all statutory interpretation questions, “[w]e begin with the statutory
    text, and end there as well if the text is unambiguous.” Connell v. Lima Corp., 
    988 F.3d 1089
    , 1097 (9th Cir. 2021) (cleaned up). The MPPAA is unambiguous that
    neither of the two forms of partial withdrawal could follow a complete withdrawal.
    First, a “70-percent contribution decline” would always follow a complete
    withdrawal, rendering the distinction between complete and partial withdrawal
    meaningless. And we presume that Congress did not intend any part of the statute
    to be “superfluous, void, or insignificant.” TRW Inc. v. Andrews, 
    534 U.S. 19
    , 31
    8
    (2001) (quoting Duncan v. Walker, 
    533 U.S. 167
    , 174 (2001)) (cleaned up).
    Specifying two types of withdrawal would hardly make sense if a partial withdrawal
    always followed a complete one.
    So too for the second form of partial withdrawal. There cannot be “a partial
    cessation of the employer’s contribution obligation” following a complete
    withdrawal. § 1385(a)(2). This is because the statute defines a complete withdrawal
    as a “permanent[ ]” cessation (1) of any obligation to contribute or (2) of all covered
    operations under the plan. § 1383(a). One cannot partially cease something after
    completely ceasing it. See Cent. States, Se. & Sw. Areas Pension Fund v. Robinson
    Cartage Co., 
    55 F.3d 1318
    , 1321 n.1 (7th Cir. 1995) (“Partial withdrawal occurs
    when a contributing employer has not completely withdrawn from the Fund but has
    undergone a long term reduction in its contribution base.”).
    Moreover, dictionary definitions highlight the difference between “partial”
    and “complete.” Black’s Law Dictionary contrasts “partial” with complete: it
    defines “partial” as “[n]ot complete; of, relating to, or involving only a part rather
    than the whole.” Partial, Black’s Law Dictionary (11th ed. 2019). It follows then
    that a partial withdrawal cannot follow a complete one as nothing is left to be
    withdrawn after the whole is removed.
    Neighboring provisions also bolster our interpretation. Section 1386 provides
    that if an employer incurs partial withdrawal liability in one year, “any withdrawal
    9
    liability of that employer for a partial or complete withdrawal from that plan in a
    subsequent plan year shall be reduced by the amount of any partial withdrawal
    liability” from the previous year. 
    29 U.S.C. § 1386
    (b)(1). This contemplates a
    partial withdrawal followed by either a partial or complete withdrawal. Turning to
    § 1387, which provides for reduction of complete withdrawal liability, the two
    subsections cover only the scenario in which an employer completely withdraws and
    then “subsequently resumes covered operations” or “renews an obligation to
    contribute[.]” 
    29 U.S.C. § 1387
    . Unlike § 1386, § 1387 does not provide that partial
    withdrawal liability following a complete withdrawal would be reduced by the
    earlier complete withdrawal. That partial withdrawals cannot follow a complete
    withdrawal explains the difference between these sections.
    The statutory text and context support our plain textual reading that a partial
    withdrawal cannot follow a complete withdrawal when the employer has not
    otherwise resumed operations or contributions. Thus, GCIU could not assess MNG
    for two partial withdrawals following its complete withdrawal.
    B
    The parties also dispute the actuary’s interest rate assumption. The MPPAA
    directs the plan actuary to determine withdrawal liability based on “actuarial
    assumptions and methods which, in the aggregate, are reasonable (taking into
    account the experience of the plan and reasonable expectations) and which, in
    10
    combination, offer the actuary’s best estimate of anticipated experience under the
    plan.” § 1393(a)(1).2 These actuarial assumptions approximate factors such as the
    “mortality of covered employees, likelihood of benefits vesting, and importantly
    future interest rates.” Concrete Pipe & Prods. of Cal., Inc. v. Constr. Laborers
    Pension Tr. for S. Cal., 
    508 U.S. 602
    , 610 (1993). The plan’s actuary uses these
    assumptions to compare the projected future payouts with the expected performance
    and determine the unfunded benefits. 
    Id.
    Within this calculation, the interest rate assumption is “arguably the most
    important.” 
    Id. at 633
    ; see also United Mine Workers, 39 F.4th at 738–39. A higher
    interest rate yields a higher projected growth, meaning “the fund will not need as
    many assets today to pay liabilities in the future.” Sofco Erectors, Inc. v. Trs. of
    Ohio Operating Eng’rs Pension Fund, 
    15 F.4th 407
    , 419 (6th Cir. 2021). On the
    2
    Section 1393(a)(2) permits the actuary to use “actuarial assumptions and methods
    set forth in the corporation’s regulations,” but neither party argues that the PBGC
    (i.e., “the corporation”) had any applicable regulations in place when this dispute
    arose. GCIU does, however, argue that the court should consider a recently proposed
    PBGC regulation as persuasive authority. See Actuarial Assumptions for
    Determining an Employer’s Withdrawal Liability, 
    87 Fed. Reg. 62316
     (Oct. 14,
    2022) (to be codified at 29 C.F.R. pt. 4213). That proposed regulation does not help
    GCIU here. While the regulation, if enacted, would permit plans to use the PBGC
    rate when calculating withdrawal liability, the regulation expressly invokes the
    PBGC’s authority under subsection (a)(2) of § 1393 when doing so. Here, by
    contrast, GCIU must justify its actuary’s assumptions under subsection (a)(1)—
    which, as indicated by the disjunctive “or” in that provision, is a separate path with
    separate requirements. The PBGC’s proposed regulation, therefore, has no bearing
    on the question presented here; nor do we express any view on the validity of the
    proposed regulation.
    11
    other hand, a lower interest rate requires more assets to pay off future liabilities,
    which in turn increases the underfunding amount and the withdrawal liability. Id.
    GCIU’s actuary used the PBGC interest rate to determine MNG’s withdrawal
    liability.   He testified that GCIU did not “take into consideration the future
    experience of the GCIU fund” or its “expected returns on the plan’s funds as
    currently invested.” The arbitrator concluded that the use of the PBGC rate did not
    comply with ERISA’s requirements, and the district court agreed. We follow our
    sister circuits and interpret the statute to require that the actuary’s assumptions and
    methods reflect the plan’s characteristics. United Mine Workers, 39 F.4th at 738;
    Sofco Erectors, 15 F.4th at 422–23.
    Though the statute appears to build in some leeway—using the term,
    “reasonable”—it specifies that these assumptions and methods must “tak[e] into
    account the experience of the plan and reasonable expectations” and “in
    combination, offer the actuary’s best estimate of anticipated experience under the
    plan.” § 1393(a)(1). The “best estimate” language means that “the actuary must
    make assumptions based on the plan’s particular characteristics when calculating
    withdrawal liability.” United Mine Workers, 39 F.4th at 738. By ignoring the
    expected returns of the plan’s assets and experience, the actuary’s estimate fell short
    of the statutory “best estimate” standard because it was not tailored to the features
    of the plan. See Sofco Erectors, 15 F.4th at 421 (“While the actuary’s true ‘best
    12
    estimate’ deserves deference, it must be his ‘best estimate of anticipated experience
    under the plan.’”).
    GCIU would have us hold that the district court erred in not considering the
    interest rate combined with other factors. In its view, the statute only requires the
    actuary’s assumptions to be reasonable “in the aggregate” and to offer the best
    estimate “in combination” with other assumptions. So GCIU contends that the
    interest rate does not need to individually account for the plan’s unique
    characteristics so long as the combination of assumptions and methods produces the
    best estimate of the plan’s anticipated experience.
    But we cannot ignore the statutory language directing the actuary to offer “the
    best estimate of anticipated experience under the plan.” § 1393(a)(1) (emphasis
    added). While actuaries may reasonably disagree as to the exact interest rate that
    best accounts for the plan’s experience and anticipated returns, “the discount rate
    assumption cannot be divorced from the plan’s anticipated investment returns.”
    United Mine Workers, 39 F.4th at 740. GCIU’s actuary testified that the PBGC rate
    ignores the expected returns on the plan’s assets. Because that rate overlooks the
    plan’s expected returns, it does not satisfy the “best estimate” standard.
    Again, the statutory context supports our interpretation. When calculations
    need not account for plan experience, ERISA is clear. The minimum funding
    provision, for example, states that the interest rate “shall be . . . determined without
    13
    taking into account the experience of the plan.” 
    29 U.S.C. § 1084
    (c)(6)(E)(iii)(I).
    This bolsters our interpretation that the “best estimate” language requires a more
    tailored interest rate. See United Mine Workers, 39 F.4th at 738 (presumption of
    meaningful variation).
    Our decision accords with Citrus Valley Estates, Inc. v. Commissioner, 
    49 F.3d 1410
    , 1414 (9th Cir. 1995). There, the Commissioner of Internal Revenue
    appealed a Tax Court judgment holding that the actuary may conservatively estimate
    actuarial assumptions in hopes of increasing initial plan funding. 
    Id. at 1413
    . In the
    Commissioner’s view, “best estimate” required a neutral assessment and the
    actuary’s use of a conservative estimate was not neutral. 
    Id. at 1414
    . We disagreed
    with the Commissioner and explained that “[t]he ‘best estimate’ language is
    ‘principally designed to ensure that the chosen assumptions actually represent the
    actuary’s own judgment rather than the dictates of plan administrators or sponsors.’”
    
    Id.
     (citation omitted). But we did not reach whether a “best estimate” had to account
    for the specific characteristics of a plan because that issue was not presented. Indeed,
    the Citrus Valley actuary arguably did account for the plan’s particular features in
    his calculations. See 
    id. at 1413
     (Tax Court noted that the plans were new and
    “lack[ed]   credible     experience,”   rendering    conservative    estimates    more
    14
    appropriate). 3
    We accordingly hold that the actuary’s use of the PBGC rate—without
    considering the “experience of the plan and reasonable expectations”—did not
    satisfy the “best estimate” standard.4

    Finally, the parties dispute whether the newspapers’ contribution histories
    should be included. When a participating employer sells its assets, any of its
    liabilities, including for withdrawals, generally remain with the employer. See
    Heavenly Hana, 891 F.3d at 842. If, however, the purchaser is (1) a successor and
    (2) has notice of the withdrawal liability, then a court may use its equitable discretion
    to hold the purchaser liable. Resilient Floor Covering, 
    801 F.3d at 1084
    . A district
    court abuses its discretion in awarding equitable relief where it “base[s] its ruling on
    an erroneous view of the law” or “on a factual finding that was ‘illogical,
    implausible, or without support in inferences that may be drawn from the record.’”
    Teutscher v. Woodson, 
    835 F.3d 936
    , 942 (9th Cir. 2016) (quoting United States v.
    3
    In its reply, GCIU argues for the first time that the district court erred in fixing the
    typographical error increasing the interest rate from 7% to 8%. “The court ‘will not
    ordinarily consider matters on appeal that are not specifically and distinctly argued
    in appellant’s opening brief.’” Clark v. Time Warner Cable, 
    523 F.3d 1110
    , 1116
    (9th Cir. 2008) (quoting Kim v. Kang, 
    154 F.3d 996
    , 1000 (9th Cir. 1998)). Because
    GCIU failed to raise this argument earlier, we do not consider it.
    4
    We express no view on an actuary’s use of the PBGC rate as a starting point or a
    component in a blended rate.
    15
    Hinkson, 
    585 F.3d 1247
    , 1262–63 (9th Cir. 2009) (en banc)).
    MNG argues that the contribution histories of the Daily Breeze and the
    Sentinel should not have been included in calculating its withdrawal liability. GCIU
    assessed liability in 2018 for MNG’s own withdrawals from the fund in 2013 and
    2014. MNG acquired these newspapers more than a decade earlier in 2006 and 2007.
    The district court concluded MediaNews and California Newspaper were successors
    to the Daily Breeze and the Sentinel, respectively, and that both had notice of the
    potential liability.
    We hold that the district court abused its discretion by not considering
    successor liability as of the asset sale dates in 2006 and 2007 and whether “it is fair”
    to impose this liability as of 2018. Heavenly Hana, 891 F.3d at 847. The record
    does not reflect whether GCIU determined MNG’s liability with respect to the
    newspapers based on the total contribution as of MNG’s complete withdrawal in
    2014 or if GCIU determined that portion of liability based on the status of the asset
    sale dates in 2006 and 2007. Any withdrawal liability that the Daily Breeze or the
    Sentinel incurred would have existed at the time of the withdrawals, which occurred
    in 2006 and 2007. See id. at 843 (“The existence of unfunded vested benefit
    liabilities on the day of [employer’s] withdrawal resulted in withdrawal liability for
    [employer] under the Act.”). The date of those asset sales in 2006 and 2007, rather
    than 2014 when MNG completely withdrew, is the relevant date to determine
    16
    whether MNG was a successor and whether the contribution histories should be
    equitably included. The district court must also consider whether “fairness could
    militate against imposing successor liability” because this doctrine sounds in equity.
    Resilient Floor, 
    801 F.3d at 1091
    .
    In reaching this conclusion, we express no opinion on whether successor
    liability should apply. We hold only that the asset sale dates in 2006 and 2007 are
    the relevant time periods to determine any liability and whether to include the
    contribution histories. We thus vacate and remand for the district court to determine
    in the first instance whether MNG has successor liability and if GCIU correctly
    applied the newspapers’ contribution histories at the time of the asset sales.
    IV
    The district court correctly held that GCIU improperly assessed liability for
    partial withdrawals after MNG completely withdrew and that GCIU erred in using
    the PBGC rate. But the district court should have considered the applicability of
    successor liability, including contribution histories, at the time of the asset sales. We
    vacate and remand for consideration of that question.
    AFFIRMED IN PART; VACATED IN PART; AND REMANDED.
