    PER CURIAM:
    This case arose in the aftermath of the catastrophic
    collapse of a bridge crane used by Kinder Morgan Bulk Terminals
    Inc. (“Appellant”) to unload coke used to fuel a steel mill
    located near Baltimore, Maryland.             Ownership of the steel mill
    and   the   bridge   crane   changed    hands    several     times   in   recent
    history.    The appellee in this case, RG Steel Sparrows Point LLC
    (“RG Steel”), 1 acquired the company that owned the steel mill and
    the bridge crane through a stock purchase on March 31, 2011.
    Following the bridge crane collapse, Appellee sued Appellant for
    negligence.    Appellee also claimed its right to indemnification
    for losses pursuant to a lease and service contract governing
    Appellant’s use of the bridge crane (“Lease”).
    Appellant   maintained     that     it   was   not   negligent   and
    that it had no duty to indemnify Appellee.                 It argued that the
    limitation-of-liability provision of a purchase order that was
    in force at the time of the crane accident applied instead of
    the Lease’s indemnity clause.          After a bench trial, the district
    court entered judgment in Appellee’s favor.                The district court
    found that the parties renewed the Lease by an implied-in-fact
    contract and concluded that the purchase order did not supersede
    1
    For ease of reference, we refer to RG Steel and the
    companies that previously owned the steel mill and the bridge
    crane collectively as “Appellee.”
    3
    the    Lease’s       indemnity          clause          under    Maryland       law       because      the
    Lease       defined       the    parties’          relationship          with    respect         to    the
    crane       and     the    purchase           order         governed     a    different         subject
    matter.       The district court held Appellant liable for over $15.5
    million,          awarding           compensatory            damages     for        destruction         of
    Appellee’s         property           and    consequential            damages       for    Appellee’s
    resulting business losses.
    In the instant action, Appellant does not challenge
    the district court’s award of compensatory damages, nor does it
    dispute      the     court’s          finding       that       the    parties       were    generally
    operating         under         an     implied-in-fact               renewal     of       the    Lease.
    Instead,       it     argues          the     district          court    erred       in    concluding
    Appellant was liable for consequential damages pursuant to the
    Lease’s indemnity clause.                         Appellant claims the district court
    should have applied the limitation-of-liability provision of a
    purchase order agreement that was in force at the time the crane
    collapsed -- a provision that Appellant contends superseded the
    Lease’s       indemnity              clause       and       foreclosed        any     consequential
    damages award.             In the alternative, Appellant avers that, even
    if    the    district       court           was   correct        to    hold    Appellant         to    the
    Lease’s       indemnity          clause,          the       district    court       erred       when    it
    qualified Appellee’s damages expert to testify and relied on the
    expert’s      calculation             in     ordering         its     award    for    consequential
    damages.
    4
    We       affirm    the     district           court’s    rulings      in    their
    entirety, albeit on different grounds.                         See Hutto v. S.C. Ret.
    Sys., 
    773 F.3d 536
    , 549-50 (4th Cir. 2014) (affirming “for a
    reason supported by the record but not relied on by the district
    court”).         Appellant is liable for consequential damages even
    under the express terms of the purchase order it wishes us to
    apply.      Furthermore,          the    district          court     did   not     abuse      its
    discretion by permitting Appellee’s damages expert to testify,
    and   it    did       not    clearly     err    in     determining         the    amount      of
    Appellee’s damages award.
    I.
    A.
    The Lease at issue originated in 1992, although both
    parties      acquired          their      interests            in     this       contractual
    relationship at a much later date.                          Under the Lease, Appellee
    leased     the    bridge       crane    to     companies       providing         stevedoring 2
    services     for       the     steel    mill’s        “A     Yard.”        The    stevedores
    undertook        to   keep     the     bridge       crane    in     good   repair       and    to
    maintain an insurance policy on it.
    The Lease contained an indemnity provision, which read
    as follows:
    2
    Stevedores load and unload cargo from ships.                          See Black’s
    Law Dictionary 1549 (9th ed. 2009).
    5
    [The stevedores] shall . . . indemnify and
    save harmless [Appellee] from and against
    all loss or liability for or on account of
    any injury (including death) or damages
    received or sustained by any person or
    persons   (including     [Appellee]    and   any
    employee, agent, or invitee thereof) by
    reason of any act or omission, whether
    negligent or otherwise, on the part of [the
    stevedores]     or   any     employee,    agent,
    subcontractor, representative, invitee, or
    business    visitor   of    [the    stevedores],
    including any breach or alleged breach of
    any statutory duty which is to be performed
    by [the stevedores] hereunder but which is
    or may be the duty of [Appellee] under
    applicable provisions of law.
    J.A. 692-93 (emphasis supplied). 3             The stevedores also “assume[d]
    the entire risk of loss, theft, or destruction of the [bridge
    crane]    resulting     from    any    cause    whatsoever.”        Id.   at   690.
    During the life of the Lease, Appellee entered into purchase
    order    contracts    with     the    stevedores      to   unload   coke-carrying
    vessels in the port.
    In December 2002, Appellant, a company that provides
    stevedoring    services,       purchased      its   predecessor’s     rights   and
    liabilities under the Lease.                 Although the Lease was set to
    terminate    at   the   end    of     July    2003,   Appellant     and   Appellee
    entered into a separate short-term interim agreement to extend
    the Lease.    Initially, this interim agreement was set to expire
    3
    Citations to the “J.A.” refer to the Joint Appendix filed
    by the parties in this appeal.
    6
    when    Appellee     and    Appellant      executed   a    long-term     agreement
    governing the use of the bridge crane or on December 31, 2003,
    whichever   occurred        sooner.        However,   Appellant    and    Appellee
    extended the interim period several times.                 When they ultimately
    were unable to reach a long-term agreement, the Lease finally
    expired at the end of 2005.
    Although Appellant never expressly renewed the Lease
    after   2005,   it    continued       to   conduct    business    with    Appellee
    “largely in the same manner as [it] had under the Lease.”                       J.A.
    600.    For example, Appellant “repeatedly referenced the Lease”
    in its communications with Appellee and it “maintain[ed] the
    [b]ridge [c]rane at its own expense,” in accord with the terms
    of the Lease.        Id. at 600–01.         Appellant also continued to use
    the bridge crane to unload ships pursuant to various purchase
    order contracts.
    B.
    1.
    On June 4, 2008, the National Weather Service issued a
    tornado watch for the central Maryland area.                  By 3:35 p.m. that
    day, wind speeds measured over 90 miles per hour.                   Despite its
    own     procedures         and    federal       regulations      which     require
    preventative       measures      during    high   winds,    Appellant     did    not
    deploy hurricane tie downs, and the bridge crane’s automatic
    7
    rail clamps had been removed at some point in the mid-1990s. 4
    Without the benefit of these safety measures, the wind toppled
    one the bridge crane’s A-frame legs, and the crane fell.
    2.
    As an immediate result of the crane collapse, Appellee
    closed   the    A     Yard   and   paid       for   emergency   repairs    to    its
    facilities.         Appellee also suffered other consequential losses
    arising from delays and increased handling charges attributable
    to the loss of the crane.            Without a crane to unload coke for
    the steel mill’s blast furnace, cargo ships carrying coke were
    required to unload their cargo at another terminal farther away
    from the blast furnace: the New Ore Pier.                  Because the New Ore
    Pier already serviced a number of ships on a regular basis, it
    struggled      to    accommodate    the    additional     traffic.        To    make
    matters worse, in order to keep the blast furnace lit, Appellee
    was required to schedule the coke-carrying ships before other
    non-coke-carrying vessels also waiting to unload at the New Ore
    Pier.    This rescheduling, coupled with port congestion caused by
    4
    Appellant does not dispute the fact that its own standard
    operating procedures “instructed [Appellant] to employ hurricane
    tie downs [on the crane to secure it] in the event of strong
    winds.” J.A. 603. Additionally, Occupational Safety and Health
    Administration regulations require bridge cranes to be equipped
    with automatic rail clamps “that prevent cranes from moving
    during high wind events.”    Id. at 614-15; see also 
    29 C.F.R. § 1910.179
    (b)(4).
    8
    re-routing the coke-carrying ship traffic to the New Ore Pier,
    resulted      in   transit    delays.        As    a     result,       Appellee    paid
    demurrage 5 fees pursuant to its contracts with these ships.
    When the A Yard reopened in the latter half of 2008,
    Appellant     used    floating   cranes      to   unload       coke     ships   and    it
    placed the coke in piles near the mill.                      Because the floating
    cranes unloaded cargo at a rate significantly slower than the
    bridge crane, Appellee faced the possibility of future demurrage
    fees.       To     mitigate    its   losses,      Appellee          renegotiated      its
    contracts with cargo ships and agreed to pay increased fees to
    offset the delays.          Appellee also needed to restore and modify a
    conveyor in order to move the coke from piles in the A Yard to
    the   blast      furnace.     Mill   operations        did    not    normalize     until
    approximately three years later, in August 2011, when Appellant
    purchased and installed its own crane at the A Yard.
    3.
    At the time of the bridge crane’s collapse on June 4,
    2008, Appellee and Appellant were bound by a February 21, 2008
    purchase      order   (“Purchase     Order”)      that       required    Appellee      to
    “unload[] up to 500,000 [tons] of coke from ships with bridge
    5
    In maritime law, the term “demurrage” applies to
    “[l]iquidated damages owned by a charterer to a shipowner for
    the charterer’s failure to load or unload cargo by the agreed
    time.” Black’s Law Dictionary 498 (9th ed. 2009).
    9
    crane [sic].”      J.A. 992.     The Purchase Order also incorporated
    the terms of another document entitled “AMUSA-100.”             See 
    id.
    The    AMUSA-100    defined     the     parties’     rights   and
    liabilities with respect to the Purchase Order.              Section 7.6 of
    the    AMUSA-100   contained    the    following    limitation-of-liability
    provision:
    In no event shall either party be liable to
    the    other    under    this    order   for
    consequential, indirect or special damages,
    including without limitation lost profits,
    revenues, production or business . . . .
    J.A. at 1000.      However, per section 1.4 of the AMUSA-100, other
    “specific     terms    agreed     in     writing”     that     “contradict[]”
    “corresponding” terms in the AMUSA-100 “shall prevail.”               Id. at
    997.
    C.
    Appellee filed suit against Appellant in the District
    Court for the District of Maryland on June 24, 2009.                  In its
    amended complaint, Appellee claimed that Appellant was negligent
    for failing to secure the bridge crane from the impending storm,
    and that it was liable in contract for breaching the Lease by
    refusing to indemnify Appellee for losses arising from the crane
    collapse.
    The parties fought this dispute at a seven-day bench
    trial in November and December 2013.          At trial, Appellee offered
    the testimony of its Corporate Controller, Jeffrey Gennuso, who
    10
    testified   about   the   general    effect   of       the    crane    collapse     on
    steel mill operations and Appellee’s contractual relationships.
    Jeffrey Cohen, an economist, provided expert testimony about the
    calculation of consequential damages Appellee suffered.
    The   district   court   reached       a    verdict       in    favor   of
    Appellee on both its negligence and breach of contract claims.
    The district court awarded a total of $15,555,884 6 to Appellee,
    which covered the following categories of damages:
    •   compensatory damages        for      loss    of     the
    bridge crane;
    •   compensatory    damages   for emergency
    repairs to Appellee’s facilities and
    for restoration and modification of the
    conveyor,    all   of   which Appellant
    conceded at trial; and
    •   consequential   damages   for demurrage
    fees, changes in commercial terms, and
    increased handling costs. 7
    Appellant does not appeal any part of the district
    court’s award of compensatory damages.              Instead, it argues only
    6
    The court’s original damages award was approximately $13
    million, but it increased this amount after correcting a
    clerical error.    This adjustment only affected the district
    court’s calculation of Appellee’s compensatory damages for loss
    of the bridge crane. See Order Granting Motion to Amend/Correct
    Clerical Error, Severstal Sparrows Point, LLC v. Kinder Morgan
    Bulk Terminals, Inc., No. 1:09-cv-01668 (D. Md. Jun. 24, 2009;
    filed May 6, 2014), ECF No. 183.
    7
    At trial, Appellant conceded it was liable for damages due
    to Appellee’s increased handling costs.

    for demurrage fees and changes in commercial terms.
    II.
    A.
    Contract Interpretation
    1.
    The threshold question is whether the district court
    correctly       concluded      that        Appellant    should       be    required    to
    indemnify Appellee, or whether an agreement between the parties
    prohibits such an award.
    Interpretation         of     a     contract      renders      a     legal
    conclusion, and we review the district court’s legal conclusions
    de novo.        See FTC v. Ross, 
    743 F.3d 886
    , 894 (4th Cir. 2014);
    Perini/Tompkins Joint Venture v. Ace Am. Ins. Co., 
    738 F.3d 95
    ,
    101 (4th Cir. 2013).           We apply substantive state law to resolve
    appeals    of    district      court       rulings     that   rest    on    state     law,
    including those involving interpretation of private contracts.
    See James v. Circuit City Stores, Inc., 
    370 F.3d 417
    , 421-22
    (4th Cir. 2004).
    The district court found that the parties renewed the
    Lease     by    an     implied-in-fact           agreement    and     therefore       “the
    Lease . . . [and] its terms and conditions were in effect” at
    the time of the crane collapse.                     J.A. 612.        In essence, the
    district       court   found   that        this    implied-in-fact        contract     was
    12
    nothing more than an agreement to renew the Lease and to amend
    its duration term.           But Appellant argued that, even if the Lease
    was     renewed      by     an    implied-in-fact          contract,       Maryland       law
    required      that    the    later-in-time          written      Purchase    Order       took
    precedence over the Lease.                Cf. Cnty. Comm’rs of Caroline Cnty.
    v. J. Roland Dashiell & Sons Inc., 
    747 A.2d 600
    , 607 (Md. 2000)
    (holding      that    a    contract       implied    in    law    cannot    supplant       an
    express contract governing the same subject).                           It argued that
    under the AMUSA-100, which was incorporated into the Purchase
    Order, Appellant was not required to indemnify Appellee.                                  The
    district court         rejected         Appellant’s    argument,      concluding         that
    the   Purchase       did    not    govern    the     same     subject     and     that    the
    Lease’s indemnity clause therefore applied.
    Appellant does not appeal the district court’s finding
    that it renewed the Lease through an implied-in-fact contract.
    Nor   does    it     dispute      the    district    court’s      conclusion       that    it
    would    be    liable       for    consequential          damages    if     the    Lease’s
    indemnity      provision         applied.      Instead,       Appellant      renews       its
    argument that the Lease did not apply and that Appellant should
    prevail by virtue of the AMUSA-100.                       We disagree, and conclude
    that Appellant would be liable pursuant to the AMUSA-100’s plain
    terms in any event.
    13
    2.
    Appellant argues that the district court erred because
    it permitted an implied-in-fact agreement to renew the Lease to
    supersede an express contract on the same subject matter -- the
    Purchase Order -- in contravention of Maryland law.                        Although
    the    Lease    and    the    Purchase    Order    address   the    same      subject
    matter, Appellant’s argument is nonetheless flawed.                        For one,
    the Maryland courts have not adopted the rule Appellant pushes;
    they   have     only   held    that   a   contract    implied      in   law   cannot
    supplant an express contract governing the same subject.                         See
    Cnty. Comm’rs of Caroline Cnty., 747 A.2d at 607.                          And even
    assuming Appellant’s interpretation of Maryland law is correct,
    the    AMUSA-100’s      plain    text     and     Appellant’s   implied-in-fact
    agreement to renew the Lease compel us to reach the same result
    as the district court: Appellant is liable to indemnify Appellee
    for consequential damages.
    3.
    When a contract is unambiguous, Maryland courts give
    full effect to the plain meaning of its terms.                      See Wells v.
    Chevy Chase Bank, F.S.B., 
    768 A.2d 620
    , 630 (Md. 2001).                          Per
    section 1.4 of the AMUSA-100, “specific terms agreed in writing”
    by the parties that contradict “corresponding . . . provisions”
    of the AMUSA-100 “shall prevail.”               J.A. 997.    The effect of this
    safety valve provision is unambiguous: the AMUSA-100 bows to
    14
    similar, yet contradicting, terms of a written agreement between
    the parties.
    There is no question that the Lease’s indemnity clause
    is a “specific term[] in writing” that “correspond[s]” to the
    AMUSA-100’s     limitation-of-liability                provision.           J.A.    997.
    Appellant instead argues that the implied-in-fact renewal of the
    Lease is not a term agreed to in writing and section 1.4 “does
    not prevent the Purchase Order from trumping any prior implied-
    in-fact   agreement.”         Appellant’s        Reply     Br.    13.     Although    an
    implied-in-fact      agreement      is   necessarily        not    in    writing,    the
    implied-in-fact agreement in this case only amended the Lease
    term   and   does    not   “contradict[]”            the   limitation-of-liability
    provision of the AMUSA-100.              J.A. 997.          The AMUSA-100 has no
    “corresponding”       temporal      limitation.            The    Lease’s    indemnity
    clause,   on   the    other      hand,   is    an    agreement     in    writing    that
    conflicts      with        the      AMUSA-100’s            limitation-of-liability
    provision.     Therefore, the AMUSA-100 unambiguously requires that
    Appellant be held to the Lease.                The Lease states that the crane
    operator “assumes the entire risk of loss of the . . . [b]ridge
    [c]rane resulting from any cause whatsoever.”                     Id. at 690.
    Therefore, we affirm the district court’s conclusion
    that   Appellant       was       required       to     indemnify        Appellee     for
    consequential damages it incurred as a result of the crane’s
    collapse.
    15
    B.
    Damages
    We now turn to whether the district court’s awards for
    demurrage    and   changes    in   commercial        terms   have    evidentiary
    support.     The evidence upon which the district court principally
    relied when ordering these awards was the calculation provided
    by Cohen; Appellant asserts Cohen was unqualified to testify as
    an expert on such matters.          Accordingly, Appellant claims the
    district court lacked sufficient evidence to order damages for
    demurrage and changes in commercial terms.
    1.
    Admissibility of Expert Testimony
    A district court’s decision to qualify and admit the
    testimony of an expert witness is one that we review for abuse
    of discretion.     “A court abuses its discretion if its decision
    is guided by erroneous legal principles or rests upon a clearly
    erroneous factual finding.”         United States v. Garcia, 
    752 F.3d 382
    , 390 (4th Cir. 2014) (internal quotation marks omitted).
    Appellant claims that the district court abused its
    discretion by qualifying Cohen as an expert to testify about
    Appellee’s    damages   for    demurrage       and    changes   in   commercial
    terms.      Appellant   concentrates      on    Cohen’s      admitted   lack   of
    experience with maritime contracts.
    16
    Rule    702    of   the    Federal    Rules     of    Evidence      permits
    expert witnesses to testify if their “scientific, technical, or
    other    special      knowledge         will    help   the       trier    of    fact    to
    understand the evidence or to determine a fact in issue,” such
    as the amount of damages due.                  Fed. R. Evid. 702.          The question
    of whether a witness is qualified to testify is context-driven
    and “can only be determined by the nature of the opinion he
    offers.”       Gladhill v. Gen. Motors Corp., 
    743 F.2d 1049
    , 1052
    (4th Cir. 1984).             Because our general preference is to admit
    evidence that will aid the trier of fact, the expert need only
    have    “sufficient         specialized        knowledge    to     assist      jurors   in
    deciding the particular issues in the case.”                             Belk, Inc. v.
    Meyer Corp., U.S., 
    679 F.3d 146
    , 162 (4th Cir. 2012) (internal
    quotation marks omitted); see Westberry v. Gislaved Gummi AB,
    
    178 F.3d 257
    , 261 (4th Cir. 1999) (“Rule 702 was intended to
    liberalize      the    introduction        of     relevant    expert       evidence.”);
    Thomas J. Kline, Inc. v. Lorillard, Inc., 
    878 F.2d 791
    , 799 (4th
    Cir. 1989) (“Generally, the test for exclusion is a strict one,
    and     the    purported       expert      must     have     neither       satisfactory
    knowledge,      skill,      experience,        training    nor     education      on    the
    issue for which the opinion is offered.”).                    In order to offer an
    opinion,      “one . . . need       not    be     precisely      informed      about    all
    details of the issues raised” or even have prior experience with
    the particular subject the testimony concerns.                           Lorillard, 878
    17
    F.3d at 799; see Fed. R. Evid. 703 (providing that “[a]n expert
    may base an opinion on facts or data in the case that the expert
    has been made aware of [at trial] or personally observed”).
    In    this   case,    Appellant     “reads     this    [qualification]
    requirement far too narrowly.”                  Belk, 679 F.3d at 162.               Although
    Cohen       had    no     prior    experience       with    maritime     contracts,         his
    opinion did not call for such expertise.                         Rather, his function
    was    to    calculate         Appellee’s      damages. 8      Cohen     has    an    MBA    in
    economics.             He created mathematical formulas for this case after
    reviewing          information         that    he     obtained        before    trial        by
    personally interviewing Appellee’s employees and reading their
    deposition         testimony.          Cohen   then    formed    his     opinion      on    the
    extent of Appellee’s losses by applying his formulas.
    The fact that Cohen had not previously analyzed issues
    that       are    specific        to   maritime     contracts     does    not     mean      the
    district court abused its discretion in admitting Cohen’s expert
    testimony.             Here, similar to the appellant in Belk, Inc. v.
    Meyer       Corp.,       U.S.,    Appellant     “provide[d]      no     support      for    its
    argument” that the economics of maritime contracts and steel
    mill operations “is so sui generis such that an expert’s lack of
    8
    Cohen testified at trial as to his limited role: “I mean,
    as an economist, looking at the data, the best I can do is make
    a comparison between two conditions and the result of that
    analysis attributes only the incremental effect to that
    condition.” J.A. 325.
    18
    expertise              in . . . these       specific       [areas]       necessarily
    disqualifies him from giving an expert opinion.”                      Belk, 679 F.3d
    at 162.           Background issues that required special knowledge of
    steel       mills      and     maritime    commerce     were   addressed      by    other
    witnesses at trial, including Gennuso. 9                 Although Cohen relied on
    information provided by other witnesses at trial to devise his
    formula, the Federal Rules of Evidence specifically authorized
    him to do so.           See Fed. R. Evid. 703.
    Thus,      we    conclude    that   the   district     court    did    not
    abuse       its     discretion       by   permitting     Cohen   to    offer       expert
    testimony         as    to     his   calculation   of    Appellee’s     damages       for
    demurrage and changes in commercial terms.
    9
    Gennuso’s testimony drew a relationship between lower
    discharge rates and the higher prices Appellee paid on coke
    contracts after the accident:
    So when we entered into new coke
    contracts, that portion that determined the
    delivery cost of the material required a
    discharge rate in order for them to properly
    calculate the freight.
    The discharge rate of 5,000 tons a day
    [using   the   floating  cranes,   which   is
    approximately 3,000 tons per day slower than
    rates achieved using the bridge crane] was
    provided to us from Kinder Morgan. . . .
    . . . So we used the 5,000 tons per day
    [discharge    rate    in   the   renegotiated
    contracts], which again was provided by
    Kinder Morgan . . . .
    J.A. 485.

    2.
    Sufficiency of Evidence for Damages Award
    a.
    When considering an appeal after a bench trial, we
    review the district court’s factual findings for clear error and
    its legal conclusions de novo.                See Universal Furniture Int’l,
    Inc. v. Collezione Europa USA, Inc., 
    618 F.3d 417
    , 427 (4th Cir.
    2010).   “A court’s calculation of damages is a finding of fact
    and is therefore reviewable only for clear error . . . .”                       
    Id.
    (internal       quotation   marks    omitted).        Furthermore,      when     “a
    district court’s factual findings turn on . . . the weighing of
    conflicting evidence during a bench trial, such findings are
    entitled to even greater deference.”                 Ross, 743 F.3d at 894
    (internal quotation marks omitted); see also F.C. Wheat Mar.
    Corp. v. United States, 
    663 F.3d 714
    , 723 (4th Cir. 2011).
    A    court   sitting    in   diversity    must   apply    state     law
    governing the threshold of proof necessary for a damages award
    and the amount of that award.            See Defender Indus., Inc. v. Nw.
    Mut. Life Ins. Co., 
    938 F.2d 502
    , 504-05 (4th Cir. 1991) (en
    banc).    According to Maryland law, “if the fact of damage is
    proven with certainty, the extent of amount thereof may be left
    to   reasonable     inference.”      David      Sloane,   Inc.   v.   Stanley   G.
    House & Assocs. Inc., 
    532 A.2d 694
    , 696 (Md. 1987) (internal
    quotation marks omitted).
    20
    b.
    Our task is to determine whether the district court
    had sufficient evidence to conclude that Appellee proved, to a
    reasonable certainty, that it suffered damages for demurrage and
    change in commercial conditions.                   We must also decide if the
    amount the district court awarded was supported by a reasonable
    inference from the record.
    During     trial,      Cohen      presented       his   calculation     of
    damages     and      concluded        that        Appellant     was       liable    for
    approximately      $2.7     million    in    demurrage     fees     and    about   $1.5
    million    in     damages    for   changes        in    commercial    terms.       The
    district court agreed with Cohen on his demurrage calculations
    and   awarded     damages     to   Appellee        accordingly.       However,     the
    district court disagreed, in part, with Cohen’s calculation of
    Appellee’s damages for changes in commercial terms.                        Therefore,
    the court awarded $1.06 million for these damages according to
    its own calculation.
    Appellant claims the district court clearly erred in
    ordering damages awards for demurrage and changes in commercial
    terms.     Regarding demurrage, Appellant concedes that Appellee
    suffered    demurrage       damages,        but    it   disagrees     with     Cohen’s
    21
    conclusions regarding the amount of such damages. 10                  Relating to
    changes in commercial terms, Appellant argues that the evidence
    failed    to   establish    the   extent      of    Appellee’s   losses       to    a
    reasonable     certainty,   and   thus     no      damages   should    have    been
    awarded in this category.
    i.
    Demurrage
    Because Appellant only challenges the amount of the
    district court’s award for demurrage, our inquiry focuses on
    whether the district court had substantial evidence to find that
    Cohen’s    demurrage   calculation       --     which    the   district       court
    accepted -- was a reasonable inference from the record.                            See
    Universal Furniture Int’l, Inc., 618 F.3d at 427; David Sloane,
    Inc., 532 A.2d at 696.       Appellant has failed to demonstrate that
    the district court’s award for demurrage was not supported by
    reasonable inferences from the record.
    Cohen’s $2.7 million figure represented the amount in
    demurrage fees that Appellee paid to ships bringing materials to
    the steel mill as a result of the crane collapse, regardless of
    whether their cargo was coke.            To arrive at this number, Cohen
    found a “baseline” demurrage figure by averaging the amounts of
    10
    Appellant concedes it is liable for only approximately
    $400,000 in demurrage damages, as opposed to the $2.7 million
    the district court awarded.
    22
    demurrage Appellee paid, per ton of cargo, for several months
    before the crane collapse.            To determine the incremental amount
    Appellee   paid    in     demurrage    due   to    the   accident,      Cohen      then
    considered the difference between the baseline figure and the
    average demurrage amount that Appellee paid over the two months
    following the accident.
    Cohen    asked     Appellee’s      accounting        personnel     if   any
    factors other than the crane collapse (e.g., changes in labor
    relations,     commercial       terms,       prices,      interest       rates      or
    inflationary      components)       could    have    caused       the    pronounced
    increase in its payment of demurrage fees.                 After reviewing the
    evidence and discussing the subject with Appellee’s accountants,
    Cohen concluded that these other factors were not responsible
    for the increase in demurrage.           He “was satisfied that one could
    safely   attribute      the   [incremental        demurrage]      to    the   bridge
    collapse.”         J.A.     327.        As   the     district       court     noted,
    “no . . . [other] data quantifying the [demurrage] loss directly
    attributable to the [b]ridge [c]rane [loss] was available.”                        Id.
    at 627-28.        The district court also had access to Gennuso’s
    testimony that one of Appellee’s employees worked with a member
    of   Appellant’s     staff     to     “determine[]       that    [the    increased]
    demurrage charges were directly a result of not being able to
    unload those ships at the A Pier.”            Id. at 217.
    23
    Nonetheless, Appellant assails Cohen’s methodology for
    failing “to account for factors that could have affected his
    demurrage    computation”         and     faults    him     for     not   investigating
    other    causes    of     the    incremental       demurrage        unrelated      to    the
    bridge     crane     accident,      such     as     “problems        with       shore-side
    equipment,       delays     in    tugs,    problems        with    the    ships,     labor
    shortages, scheduling issues, etc.”                  Appellant’s Br. 55-56, 58.
    Yet Appellant offered no evidence to support its speculative
    claim     that      other        potential       factors          that    “could        have
    significantly affected the amount of demurrage charges” actually
    had such an effect.         Id. at 56.
    In light of the considerable deference we afford to
    district     court      findings     during        bench    trials,       the     record’s
    surplus of support for the court’s factual findings, and the
    wholly speculative nature of Appellant’s argument, we conclude
    the     district     court’s       damages       award     for      demurrage      was     a
    reasonable inference from the record.
    ii.
    Changes in Commercial Terms
    After losing the bridge crane, Appellee renegotiated
    several of its contracts with coke-carrying vessels to account
    for the increased unload time and to avoid further demurrage.
    Gennuso testified that unloading delays increased transportation
    costs and, in turn, drove up the price Appellee paid for coke.
    24
    Cohen   relied   on    this     assumption     to    calculate      an   approximate
    damages amount for changes in commercial terms.
    The district court did not take issue with Cohen’s
    method, but it found that his calculation of the discharge rate
    in   the    post-collapse     period     was   not       entirely   reliable.      It
    concluded     that     Cohen’s    analysis       failed      to     recognize   that
    Appellant built a new crane in the A Yard in the second half of
    2011, which dramatically increased discharge rates above those
    measured soon after the bridge crane collapsed.                          Accordingly,
    the district court awarded Appellee approximately $1.06 million
    for changes in commercial terms, which was substantially less
    than the approximately $1.5 million Appellee sought.
    But Appellant argues that the district court should
    not have awarded damages for changes in commercial terms at all.
    In   this    regard,    Appellant       argues      that     the    district    court
    committed     three    errors    in    relying      on   Cohen’s    calculation    of
    damages for changes in commercial terms: (1) Cohen only reviewed
    two shipping contracts in assessing the incremental discharge
    rate, which was an unreliably small sample size; (2) Cohen did
    not examine certain other potential causes for the change in
    contract terms, such as market fluctuations in the price of coke
    and Appellee’s credit history; and (3) Cohen lacked a basis to
    assume a positive correlation between a decreased discharge rate
    and the price of coke.                Appellant claims that these alleged
    25
    deficiencies              rendered       Cohen’s         calculation             of      damages
    unreasonably             uncertain;    therefore,        the       district      court     lacked
    sufficient          evidence    to     conclude      Appellee        proved       damages       for
    changes       in    commercial        terms.      Each     of      these      arguments       lacks
    merit.
    First,       Appellant’s        attack    on     Cohen’s        methodology       --
    that     it        was     fatally     uncertain        because          it    relied     on    an
    impermissibly small sample size for calculating the incremental
    discharge rate -- is plainly inconsistent with the evidence.
    Cohen viewed the two charter contracts merely to confirm that
    the pre- and post-accident discharge rates were accurate.                                        As
    the district court noted, “Mr. Cohen testified that he did not
    rely on the contracts to glean the prices charged for coke, but
    instead sought verification of the discharge rates.”                                  J.A. 633.
    In any event, as we discussed with respect to the demurrage
    award, Cohen bolstered his conclusion by ruling out other causes
    for the delays that precipitated Appellee’s renegotiation of the
    coke shipping contracts.
    We likewise reject Appellant’s two remaining arguments
    because       Appellant        failed     to     support        these         challenges       with
    evidence.            The    district     court’s        decision         to    credit    Cohen’s
    testimony was not clearly erroneous.                          No evidence suggests the
    district       court’s        conclusion       was   not       a    “legally       justifiable
    inference”          from     Cohen’s     testimony       and       the     entirety      of    the
    26
    record.     Miller v. Mercy Hosp., Inc., 
    720 F.2d 356
    , 365 (4th
    Cir. 1983).
    Appellant       offered      no      evidence    indicating         that   the
    possible      alternative            causes       actually         impacted       Cohen’s
    calculations.        In fact, Appellant argued to the district court
    “that coke prices did not appreciably change from prices before
    the   [b]ridge      [c]rane    collapse.”            J.A.   632.        Furthermore,     a
    district court’s decision on how much weight to give testimony
    at a bench trial is one that we afford great deference.                                See
    Ross, 743 F.3d at 894.              This principle applies to the district
    court’s determination of whether Cohen sufficiently ruled out
    possible alternative causes for the increase in the contract
    prices     Appellee    paid     for      coke      after     the    accident.          See
    Westberry, 
    178 F.3d at 265
     (providing that, unless a plaintiff’s
    expert provides “no explanation” for why a defendant’s suggested
    alternative causes are not plausible, these alternative causes
    “affect    the   weight       that    the     jury    should     give     the    expert’s
    testimony     and     not     the     admissibility         of     that    testimony”).
    Without question, Gennuso logically linked the crane accident to
    actual changes in the contract price for coke.                            Here, whether
    Cohen sufficiently ruled out other causes is only a question of
    how much weight to give Cohen’s opinion, and so we defer to the
    district court’s conclusion.
    27
    Further,       although     Appellant      argues    Cohen       improperly
    assumed a positive correlation between decreased discharge rates
    and the price of coke, Appellant again failed to point to any
    evidence     in    the      record   showing      that    the     district      court’s
    decision to credit this assumption was clear error.                             Cohen’s
    reasoning      that    discharge       rates    affect     transportation        costs,
    which   then      impact    the   cost   of     coke,    was    built    on   Gennuso’s
    testimony that Appellee renegotiated coke shipping contracts at
    a higher rate to account for slower discharge rates caused by
    the crane collapse.
    Mindful that district court findings in a bench trial
    should be given the “highest degree of appellate deference,” we
    find    no   reason    to    upset   the   district       court’s       determination.
    F.C. Wheat Mar. Corp., 
    663 F.3d at 723
     (internal quotation marks
    omitted).      The district court had a sufficient basis to conclude
    that Cohen proved Appellee’s damages for changes in commercial
    terms to a reasonable certainty.
    III.
    For      the    foregoing     reasons,       the    judgment       of   the
    district court is
    AFFIRMED.
    28
    DIAZ, Circuit Judge, concurring:
    Although I share the majority’s view of the outcome of this
    case, I diverge slightly in my understanding of the nature of
    the relationship between the parties after the expiration of the
    Interim Agreement in 2005.               I would find that Kinder Morgan was
    bound by the Lease terms as a holdover tenant, and that the
    later purchase orders do not supersede the Lease terms in this
    case because they cover a different subject matter.
    The record before the court does not support the conclusion
    that Kinder Morgan objectively intended to be bound by the terms
    of the 1992 Lease after the expiration of the final Interim
    Agreement in 2005.                To the contrary, the undisputed evidence
    suggests       that    Kinder     Morgan   specifically          did    not   wish    to    be
    bound by the original lease terms because it wanted to negotiate
    a     new    long-term       agreement     in       order   to    invest      in     capital
    improvements          to    the   “A”    Pier.        In    fact,      when   RG     Steel’s
    predecessor proposed a new contract that would have extended the
    interim period through March 2006, Kinder Morgan refused to sign
    it.         Kinder    Morgan’s       occasional      post-2005      references       to    the
    expired Lease do not alter this conclusion, and indeed, some of
    the    references          support    Kinder    Morgan’s     assertion        that    it    no
    longer considered itself bound by the Lease.                            See, e.g., J.A.
    888 (in which Kinder Morgan references “the previous contractual
    relationship” under the Lease) (emphasis added).
    29
    Nonetheless,           Kinder     Morgan’s           actions          are         entirely
    consistent with a holdover tenancy.                         Importantly, a holdover
    tenancy under Maryland law is not based on objective assent or
    intent to be bound by a lease.                  Rather, it exists automatically
    when a lessee overstays the term of a leasehold.                                  See 
    Md. Code Ann., Real Prop. § 8-402
    (c)          (West        2015)    (“Unless         stated
    otherwise in the written lease . . . when a landlord consents to
    a holdover tenant remaining on the premises, the holdover tenant
    becomes . . . a periodic month-to-month tenant . . . .”).                                      When
    a tenant holds over, the tenancy remains “on all the terms and
    conditions of the original lease.”                   Straley v. Osborne, 
    278 A.2d 64
    , 68 (Md. 1971).
    Despite    demonstrating         an    intent       not     to   be     bound      by     the
    terms    of     the    Lease     in     its     negotiations            with       RG     Steel’s
    predecessors,         Kinder    Morgan       undoubtedly          remained        at    Sparrows
    Point    after     the    final       Interim       Agreement       expired.              As    the
    district      court      observed,       it    also        continued         to     pay        rent,
    utilities, and wharfage fees to the owners of the property, and
    it continued to operate and maintain the Bridge Crane.                                     Kinder
    Morgan also failed to take any of the actions that would have
    been    required       upon    the     expiration          of    the    Lease,          including
    surrendering the property and conducting a final inspection of
    the Bridge Crane.             Based on Kinder Morgan’s behavior, I agree
    with the district court’s conclusion that the purchase orders
    30
    alone could not possibly be construed to govern the parties’
    relationship.        And   although    Kinder    Morgan     did   not   consider
    itself bound by any agreement with RG Steel’s predecessors, its
    continued presence at the site and “good faith” adherence to the
    terms of the Lease is consistent with a holdover tenancy.
    Due to the holdover tenancy, the Lease terms remained in
    force beginning on January 1, 2006, to the extent the parties
    did not replace those terms with express, written agreements.
    Among the Lease terms was an entire section dedicated to the
    Bridge Crane wherein Kinder Morgan and its predecessors agreed
    to assume “the entire risk of loss, theft, or destruction of the
    No. 4 Bridge Crane resulting from any cause whatsoever.”                      J.A.
    690.     The Lease’s indemnity provision further clarified Kinder
    Morgan’s liability, stating that it would “indemnify and save
    harmless” the crane’s owner from any loss or liability resulting
    from any damages sustained by the owner as a result of any act
    or omission of Kinder Morgan, “whether negligent or otherwise.”
    J.A. 692.      Undoubtedly, the terms of the Lease directly covered
    the subject matter of Kinder Morgan’s liability in the event of
    damage    to   the   Bridge   Crane,    and     did   not   provide     for   any
    limitation on consequential damages.
    In February 2008, the parties entered into a purchase order
    under which Kinder Morgan agreed to unload “up to 500,000 nton
    of coke from ships with Bridge Crane.”                J.A. 992.    Delivery of
    31
    the coke was promised approximately four months later, and the
    purchase order provided for a delivery location, a unit price,
    and a total price.              The purchase order also made reference to
    the buyer’s terms and conditions, contained in a document called
    the    AMUSA-100       “General     Purchasing       Conditions      for    Purchase     of
    Goods or Services.”             The first sentence of the AMUSA-100 clearly
    states its scope: “These General Purchasing Conditions (“GPC”)
    shall     apply        to     the   purchase      of      any     materials,      items,
    products . . . and            any   related     services     (“Goods”)       offered    or
    provided by suppliers (‘Seller’).”                     J.A. 997 (emphasis added).
    The     terms    of     the     AMUSA-100     thus     explicitly        apply   to     the
    procurement       of    specific     goods    and      services,     addressing        such
    topics     as     price       adjustments,       delivery,        inspection     of    the
    product, and warranties on the goods exchanged.
    Although the “Warranty – Liability” portion of the terms
    states    that        neither    party   will     be     liable    for     consequential
    damages “under this order,” that language is preceded by five
    sections referring to the nature of the goods delivered under
    the purchase order, including their quality, performance, and
    timely delivery.             The limitation on liability under the purchase
    order is narrow in scope: it only covers liability resulting
    directly from Kinder Morgan’s delivery of goods and services to
    RG    Steel     and    its    predecessors.        The    purchase       order   and    its
    accompanying terms do not address Kinder Morgan’s liability in
    32
    the event that it fails to maintain and protect the Bridge Crane
    itself, despite the fact that Kinder Morgan was unloading coke
    at    the   time    of   the    accident.       I    would   therefore       find    that
    because the terms of the Lease were the only manifestation of
    the parties’ intent with respect to the damages caused by the
    accident, those terms apply and there is no limitation on Kinder
    Morgan’s liability. *
    Ultimately, I agree with the majority’s view that the terms
    of    the   Lease    remained     in   force    and      continued    to    govern   the
    parties’ relationship at the time of the accident.                         Although the
    parties subsequently entered into written purchase orders, those
    orders (and their accompanying terms and conditions) addressed a
    subject matter distinct from the events of this case and thus do
    not    supersede      the      Lease   terms.        I    therefore    join     in   the
    majority’s         conclusion      that     Kinder       Morgan   is       liable    for
    consequential damages, and that the district court did not err
    in relying on Appellee’s expert in calculating those damages.
    *
    The majority applies the Lease terms indirectly through
    the AMUSA-100’s “safety valve provision.” But because I do not
    agree that the limitation on liability in the purchase order and
    the      indemnity     clause      in      the     Lease     are
    “corresponding . . . provisions” “in contradiction with” each
    other, J.A. 997, I conclude that Kinder Morgan’s liability for
    the accident is governed only by the Lease.
