    ASLI CAROME, APPELLANT/CROSS-APPELLEE,
    v.
    PATRICK CAROME, APPELLEE/CROSS-APPELLANT.
    Appeals from the Superior Court
    of the District of Columbia
    (2018-DRB-001768)
    (Hon. William W. Nooter, Trial Judge)
    (Argued February 8, 2023                                    Decided May 11, 2023)
    Ayesha N. Khan for appellant/cross-appellee.
    Steven P. Lehotsky for appellee/cross-appellant.
    Before BECKWITH and MCLEESE, Associate Judges, and GLICKMAN, Senior
    Judge.
    MCLEESE, Associate Judge: Appellant/cross-appellee Asli Carome and
    appellee/cross-appellant Patrick Carome challenge several rulings by the trial court
    relating to the interpretation of a premarital agreement. We affirm in part, reverse
    in part, and remand the case for further proceedings.
    2
    I. Background
    The following facts appear to be undisputed for current purposes. The parties
    were married in 2010. They each entered the marriage with significant assets. Ms.
    Carome initially took care of the parties’ children from prior marriages, but she
    obtained a position as an attorney with the federal government in 2012. Mr. Carome
    was a partner at a private law firm throughout the marriage, earning over one million
    dollars a year.
    The parties entered into a premarital agreement to govern the treatment of
    their assets before, during, and after the marriage. With specified exceptions, the
    agreement requires the parties to pay their earnings during the marriage into a joint
    marital account. The parties contributed to a joint account pursuant to the agreement
    until September 2013, when Mr. Carome closed the account.
    The parties formally separated in November 2017. Ms. Carome subsequently
    filed a petition for divorce, and Mr. Carome filed a counter-petition. The trial court
    issued a divorce decree and resolved numerous contested issues. The present
    appeals focus entirely on claims relating to the premarital agreement.
    3
    After a bench trial, the trial court concluded that Mr. Carome had breached
    the premarital agreement by failing to deposit earnings into the joint account
    between 2013 and the parties’ separation in 2017. Both parties introduced expert
    testimony regarding the amount of the underpayment by Mr. Carome. The trial court
    ultimately awarded Ms. Carome more than $440,000 in damages.
    II. Earnings “During the Marriage”
    As previously noted, the premarital agreement generally requires the parties
    to contribute their earnings to a joint account “during the marriage.” Agreement
    §§ 1.5, 1.7. Specifically, § 1.7(A) of the agreement provides, in relevant part:
    Each party agrees that he or she shall transfer to a Marital
    Account the entire portion (if any) of his or her earnings
    acquired during the marriage which is not applied towards
    or otherwise set aside to satisfy the obligations and
    arrangements described in items (i) through (vii) of this
    Paragraph A.
    The parties dispute the meaning of the phrase “during the marriage” in that
    provision. Ms. Carome argues that the phrase should be interpreted to mean until
    the date of divorce, so that Mr. Carome was obliged to make contributions to the
    4
    joint account until the divorce. Mr. Carome argues that the phrase should be
    interpreted to mean until the date of separation.
    Noting that neither party had sought consideration of extrinsic evidence, the
    trial court ruled as a matter of law that “during the marriage” under § 1.7(A) does
    not include the period after the parties’ separation.
    We review de novo the trial court’s interpretation of the phrase “during the
    marriage” in § 1.7(A). See, e.g., Abdelrhman v. Ackerman, 
    76 A.3d 883
    , 887-88
    (D.C. 2013) (Where extrinsic evidence is not at issue, “[t]he proper interpretation of
    a contract . . . is a legal question, which this court reviews de novo.”) (italics and
    internal quotation marks omitted). Our task is to “determine what a reasonable
    person in the position of the parties would have thought the disputed language
    meant.” Dyer v. Bilaal, 
    983 A.2d 349
    , 355 (D.C. 2009) (internal quotation marks
    omitted). We “look[] to the entire language of the agreement, not merely a portion
    thereof,” and we consider “the customary, ordinary and accepted meaning of the
    language used.” James G. Davis Constr. Corp. v. HRGM Corp., 
    147 A.3d 332
    , 340
    (D.C. 2016) (internal quotation marks omitted).
    5
    Although the agreement is not entirely clear on the point, we agree with the
    trial court that the agreement is better read to establish the date of separation as the
    end point of the parties’ obligation to contribute earnings to the joint account.
    We acknowledge that a number of considerations support Ms. Carome’s
    contrary interpretation. First, in ordinary language, marriage is understood to end at
    the moment of divorce, not at the moment of separation. Compare, e.g., Divorce,
    Webster’s Third New Int’l Dictionary 664 (2002) (“1: a legal dissolution in whole
    or in part of a marriage relation . . .”), with, e.g., Separation, id. at 2070 (“4a(1):
    cessation of cohabitation between husband and wife by mutual agreement”).
    Second, the ordinary legal understanding is the same. See Divorce, Black’s Law
    Dictionary 582 (10th ed. 2014) (“The legal ending of a marriage . . . .”); Separation,
    id. at 1572 (“1. An arrangement whereby a husband and wife live apart from each
    other while remaining married . . . .”); see also 
    D.C. Code § 16-920
     (final decree of
    divorce dissolves bonds of matrimony); Powell v. Powell, 
    457 A.2d 391
    , 393 (D.C.
    1983) (approving trial court’s treatment of property acquired after separation and
    before divorce as property acquired “during the marriage”). Third, several other
    provisions of the agreement seem to indicate that marriage under the agreement
    continued after separation. See, e.g., Agreement § 3.2(A) (requiring parties to
    6
    designate each other as survivor beneficiary of portions of retirement plans derived
    from contributions made “during the marriage and before separation”).
    In our view, however, those considerations are outweighed by strong
    indications to the contrary that the obligation to contribute to the joint account ends
    at the point of separation. First, Recital H to the agreement refers to separation as a
    form of “dissolution of the[] marriage.” Agreement Recital H. The agreement
    expressly incorporates the recitals, which therefore are an operative part of the
    agreement. See Agreement § 12.16 (“The Recitals set forth above are hereby
    incorporated by reference as part of this Agreement.”); Goldman v. Lustig, 
    237 So. 3d 381
    , 384 n.2 (Fla. Dist. Ct. App. 2018) (recitals incorporated into agreement are
    binding); First Bank & Tr. Co. of Ill. v. Vill. of Orland Hills, 
    787 N.E.2d 300
    , 308
    (Ill. App. Ct. 2003) (“[P]reliminary recitals in [an] agreement of themselves are not
    binding unless referred to in [the] operative portion of [the] agreement [so] as to
    show a design that they should form a part of it[.]”) (brackets and internal quotation
    marks omitted); cf. Trilon Plaza, Inc. v. Comptroller of N.Y., 
    788 A.2d 146
    , 151
    (D.C. 2001) (rejecting argument that recital “can never be treated as an operative
    part of a contract”) (internal quotation marks omitted). Recital H clearly treats
    separation as the end of the marriage.
    7
    Second, Recital F to the agreement describes the parties as “self-supporting”
    and states that the parties “desire to waive any rights or claims to support from the
    other in the event of a separation or divorce.” Agreement Recital F. That provision
    undermines the theory that the parties would be obliged to continue contributing to
    a joint account during a period of separation.
    Third, various other provisions in the agreement appear to indicate that
    marriage for purposes of the agreement ended at the moment of separation. See,
    e.g., Agreement § 2.4(E) (successor home may be sold during marriage or “disposed
    of upon a separation or divorce”).
    Fourth, the agreement in a number of places draws the line between marital
    property and separate property by focusing on the date of separation rather than the
    date of the divorce. See, e.g., Agreement § 1.5(iv)-(v) (certain retirement benefits
    attributable to contributions from date of marriage until separation are marital
    property); id. § 1.6(ii) (retirement benefits earned after separation are separate
    property). Those provisions support the view that money earned after separation
    should not be viewed as marital property to be contributed to a joint account.
    8
    Finally, the agreement provides that separation triggers the obligation to
    divide marital property, and the value of the marital property is to be assessed as of
    the date of separation. See Agreement § 5.2(A) (“In the event of the parties’
    separation, the parties’ marital property shall be disposed of . . . ,” and “[e]ach party
    shall receive one-half of the net value of all marital property owned by the parties as
    of the date of separation.”). That provision strongly undermines the idea that the
    parties would continue creating substantial amounts of new marital property after
    the date of separation, particularly given that the agreement contains no direction
    about how to divide such post-separation marital property.
    The foregoing considerations on both sides lead us to the following
    conclusions. The agreement is not carefully drafted, and it is internally inconsistent
    on the general question whether the marriage should be understood to end at the
    moment of separation or at the moment of divorce. The answer to that question
    under the agreement might well vary depending on the specific provisions at issue.
    Focusing on the provisions most directly at issue here, however, we agree with the
    trial court that the agreement is better understood to establish separation as the end
    point of the obligation to contribute to the joint account.
    9
    We are not persuaded by Ms. Carome’s additional arguments to the contrary.
    First, Ms. Carome refers in passing to extrinsic evidence concerning the
    interpretation of the agreement. The trial court ruled, however, that neither party
    had asked the court to consider extrinsic evidence in interpreting the contract. Ms.
    Carome has not challenged that ruling in this court. We therefore decline to consider
    extrinsic evidence.
    Second, Ms. Carome argues that the phrase “during the marriage” must be
    given the meaning that phrase is given in District of Columbia statutes and the
    decisions of this court. We disagree. It is true that the agreement provides that the
    “interpretation of th[e] [a]greement shall be determined and governed by the laws of
    the District of Columbia.” Agreement § 12.13. The law of the District of Columbia,
    however, is that terms in a contract ordinarily should be interpreted based on the
    wording of the contract and applicable principles of contract interpretation, not
    simply by relying on definitions that can be found in a statute or a decision of this
    court. See generally, e.g., Convit v. Wilson, 
    980 A.2d 1104
    , 1114-15 (D.C. 2009)
    (when interpreting contract, court follows “established rules of contract
    interpretation,” looking first to language of contract) (internal quotation marks
    omitted). To be clear, we agree with Ms. Carome that definitions of the phrase
    “during the marriage” in statutes and the decisions of this court are relevant. See,
    10
    e.g., Parker v. U.S. Tr. Co., 
    30 A.3d 147
    , 152 (D.C. 2011) (stating that where
    contract provided that it would be interpreted in accordance with laws of District of
    Columbia, argument that contractual term should be given statutory definition has
    “some force and is, at a minimum, reasonable”); Morgenstern v. Nationwide
    Agribusiness Ins. Co., 
    78 F. App’x 485
    , 491 (6th Cir. 2003) (“[S]tatutory definitions
    can be relevant in construing a contract . . . .”). We do not, however, view such
    definitions as necessarily dispositive, at least in the absence of contractual language
    explicitly adopting a particular definition taken from statute or case law. Cf., e.g.,
    Ins. Co. of N. Am. v. Godwin, 
    361 N.Y.S.2d 461
    , 464 (App. Div. 1974) (“[W]e are
    here interpreting a policy of insurance, and [the insured] is entitled to have it
    construed as a contract and not necessarily according to the statutory definition.”).
    For the reasons we have stated, we do not find the definition of “during the marriage”
    in statute and case law to be dispositive in this case.
    Finally, Ms. Carome argues that ambiguities in the agreement should “be
    construed strongly against the drafter,” who was Mr. Carome. Intercounty Constr.
    Co. v. District of Columbia, 
    443 A.2d 29
    , 32 (D.C. 1982) (internal quotation marks
    omitted).   That consideration favors Ms. Carome, but we do not view the
    consideration as determinative. The rule disfavoring the drafter of an agreement
    comes into play only if other principles of contract interpretation leave the court
    11
    unable to give the contractual language at issue a definite meaning.               See 
    id.
    (explaining that if, after court attempts to determine what reasonable person would
    have thought contract meant, “a contract and its terms are still not subject to one
    definite meaning, the ambiguities remaining in the contract will be construed
    strongly against the drafter”) (citation and internal quotation marks omitted); see
    also Am. Bldg. Maint. Co. v. L’Enfant Plaza Props., Inc., 
    655 A.2d 858
    , 863 (D.C.
    1995) (canon of construction disfavoring drafter of agreement “is a secondary
    standard of interpretation . . . inferior to . . . other authority revealing [the parties’]
    understanding”) (internal quotation marks omitted).          For the reasons we have
    explained, we conclude that the agreement, read as a whole, can be given a definite
    interpretation.
    In sum, we affirm the trial court’s ruling that Mr. Carome was not required by
    the agreement to contribute to the joint account after the parties separated in
    November 2017.
    III. Payments to Defined-Benefit Retirement Plan
    As previously mentioned, the agreement provides for exceptions to the
    parties’ obligation to contribute their earnings to the joint account. Agreement
    12
    § 1.7(A). One of those exceptions is for “contributions to retirement plans or
    accounts.” Id. § 1.7(A)(iii). That exception is limited, however, by § 1.7(D), which
    caps such deductions for a given year to a percentage of the amount that the party
    contributed to the joint account that year. Id. § 1.7(D) (“During the marriage, the
    total amount of current earnings that either party may contribute in any calendar year
    to retirement plans or accounts shall not exceed . . . one-half (50%) of the total
    amount that he or she contributes from current earnings to Marital Accounts during
    the same calendar year.”).
    Relying on those provisions, Ms. Carome argues that Mr. Carome could not
    properly deduct any amounts relating to retirement contributions in years in which
    Mr. Carome did not pay any earnings into the joint account. To put the point
    mathematically, Ms. Carome argues that 50% of $0 = $0.
    Mr. Carome does not dispute that argument with respect to some retirement
    payments, such as payments to his 401(k) retirement plan. Mr. Carome does dispute
    that argument, however, with respect to payments into his law-firm defined-benefit
    retirement plan. Mr. Carome makes two principal points. First, he argues that his
    defined-benefit plan is separate property under the agreement. See Agreement
    § 1.6(iii) (Mr. Carome’s defined-benefit plan and certain other retirement plans are
    13
    separate property, “notwithstanding that [Mr. Carome] may make contributions to
    such plans or accounts during the marriage from his earnings”). Second, he argues
    that he did not make contributions to the defined-benefit plan, but rather his law firm
    did. The trial court ruled for Mr. Carome on this issue. We review that ruling de
    novo, Abdelrhman, 
    76 A.3d at 887-88
    , and we come to a contrary conclusion.
    It is true that Mr. Carome’s defined-benefit plan is separate property under the
    agreement. Agreement § 1.6(iii). That is an entirely separate question, however,
    from the question whether Mr. Carome was entitled under the agreement to a
    deduction from his earnings for payments made into the defined-benefit plan. The
    latter question is governed by § 1.7(D) of the agreement, which places a cap on the
    amount that can be deducted from earnings for “contributions to retirement plans.”
    Id. § 1.7(D). Nothing in the language of that provision suggests that the cap is
    limited to retirement-plan payments that are marital property rather than separate
    property. Cf. id. § 1.7(A)(iii) (acknowledging that parties may use earnings to
    satisfy separate obligations, including, “except as limited in Section 1.7(D),
    contributions to retirement plans”) (emphasis added). To the contrary, as Mr.
    Carome acknowledges, the obvious purpose of the cap is to limit the amount of
    income a party can shelter in a given year from the obligation to make contributions
    to the joint marital account. That purpose applies equally to all retirement payments,
    14
    whether those payments went to retirement accounts that would be marital property
    or to retirement accounts that would be separate property.
    Mr. Carome does not dispute that the payments into the defined-benefit plan
    came from his earnings. Thus, the sole remaining issue is whether those payments
    were “contributions” within the meaning of § 1.7(D) of the agreement. We conclude
    that the payments were contributions. Section 1.6(iii) of the agreement implies as
    much, stating that Mr. Carome “may make contributions to such plans or accounts
    [including the defined-benefit plan] during the marriage from his earnings.”
    Agreement § 1.6(iii). Section 3.2(A) of the agreement is clearer on the point,
    providing that during the marriage Mr. Carome was obliged to name Ms. Carome as
    the survivor beneficiary of all portions of the defined-benefit plan “derived from
    contributions of earnings that [Mr. Carome] made during the marriage and before
    separation.” Id. § 3.2(A). Those provisions of the agreement in our view make clear
    that payments to the defined-benefit plan were understood to be contributions.
    We are not persuaded by Mr. Carome’s arguments to the contrary. Mr.
    Carome argues that the defined-benefit payments were mandatory, but nothing in
    the language or logic of § 1.7(D) turns on whether Mr. Carome could unilaterally
    determine the amount of the payment at issue. Mr. Carome also argues that
    15
    payments to the defined-benefit plan were directly implemented by his law firm,
    rather than through transactions that Mr. Carome himself made.            We are
    unconvinced by that distinction. It is undisputed that the payments were from Mr.
    Carome’s earnings and went to his defined-benefit plan. We do not see why it is
    relevant that the law firm automatically conducted those transactions on Mr.
    Carome’s behalf.
    Accordingly, we reverse the trial court’s ruling permitting Mr. Carome to
    deduct payments to the defined-benefit plan during the years when Mr. Carome
    failed to make required payments into the joint account. We remand for further
    proceedings to revise the damages award accordingly.
    IV. 2017 Partnership Compensation
    The parties separated in November 2017. They dispute whether, under the
    agreement, Mr. Carome’s earnings during the marriage should include a prorated
    amount of the compensation Mr. Carome received from his law firm for that year.
    Mr. Carome argues that his law firm’s profits were “speculative and contingent”
    until after the end of 2017, and thus Mr. Carome did not earn anything “concrete[]”
    between January and November 2017, except for the right to a share of the firm’s
    16
    profits paid out after the end of 2017, by which time the parties had separated. Mr.
    Carome therefore contends that all of his 2017 compensation should be treated as
    separate property under the agreement.
    The trial court concluded that Mr. Carome’s earnings from his law firm from
    January to November 2017, even if not known in their exact amount at the time of
    separation, were marital property under § 1.3 of the agreement, which includes
    “accrued but unpaid compensation” in the definition of “earnings.” Agreement
    § 1.3; see also id. § 1.7(A) (requiring parties to transfer earnings to marital account,
    subject to exceptions). In support of that ruling, the trial court pointed out that the
    agreement treats a prorated estimate of Mr. Carome’s 2010 law-firm compensation
    as having accrued in July 2010 and thus as being a premarital asset rather than a
    marital asset. See Agreement, Exh. B, at 2-3 n.16 (treating “[v]ery rough estimate”
    of prorated 2010 law-firm compensation as “pre-marital asset”). We review the trial
    court’s ruling de novo, Abdelrhman, 
    76 A.3d at 887-88
    , and we affirm.
    Whatever meaning might reasonably be given to the words “accrued but
    unpaid compensation” in a different agreement, this agreement treats a prorated
    portion of Mr. Carome’s compensation in 2010 as an asset of Mr. Carome’s in July
    2010, even though the amount of Mr. Carome’s 2010 compensation would not be
    17
    precisely known until 2011. We see no justification under the agreement for treating
    Mr. Carome’s 2017 compensation differently. We therefore agree with the trial
    court that a prorated amount of Mr. Carome’s 2017 law-firm compensation should
    be treated as “accrued but unpaid compensation.”
    V. Mr. Rollinger’s Expert Report
    Ms. Carome argues that the trial court erred by permitting an expert, Eric
    Rollinger, to testify on Mr. Carome’s behalf at trial, even though Mr. Carome did
    not provide Ms. Carome with an adequate written report from the expert, as required
    by Super. Ct. Dom. Rel. R. 26(a)(2)(B). We agree. We conclude, however, that the
    error was harmless.
    A. Factual and Procedural Background
    Mr. Rollinger testified for Mr. Carome as an expert concerning the calculation
    of damages, if any, owed based on Mr. Carome’s failure to make payments into the
    joint account. Under Super. Ct. Dom. Rel. R. 26(a)(2)(B), Mr. Carome was required
    to provide Ms. Carome with a written report from Mr. Rollinger before trial. Such
    reports must contain “a complete statement of all opinions the witness will express
    18
    and the basis and reasons for them” and “the facts or data considered by the witness
    in forming them.” Super. Ct. Dom. Rel. R. 26(a)(2)(B)(i)-(ii).
    Mr. Carome provided a written report from Mr. Rollinger, apparently first in
    February 2019 and then in revised form in March 2019. The report does not contain
    a single complete sentence. Rather, the first page of the report is a chart reflecting
    Mr. Rollinger’s overall conclusions as to how much Mr. Carome earned during the
    marriage; what amounts were appropriately subtracted from those earnings under
    various provisions of the premarital agreement; the amounts of Mr. Carome’s
    “Contributions to the Marriage” in various categories, such as “[Mr. Carome] Direct
    Contribution”; and the amounts of Mr. Carome’s payments of “Other Necessary
    Expenses” in various categories, such as “Business Expense.” The chart concludes
    that Mr. Carome “over-contributed” to the marriage by more than $350,000.
    The second page of the report is a graph depicting Mr. Carome’s cumulative
    contributions to the marriage on a monthly basis. The third page of the report is a
    slightly expanded version of the first page, adding a list of the amounts of various
    “Non-Counted Items,” such as “Other Living Expenses.” The report then contains
    month-by-month breakdowns of the chart on the first page of the report.
    19
    Finally, the report contains a spreadsheet of approximately 300 pages. That
    spreadsheet reflects over 20,000 individual transactions, identified by date, account,
    and amount. The spreadsheet also has boxes labeled “Description,” “Memo,”
    “Category,” and “Tag.” For many transactions, one or more of those boxes are not
    filled in. Examples of the comments in the “Memo” box include “Non-joint portion
    of 11/02/10 Invoice,” “Transfer – all joint,” and “Misuse of credit card by [Ms.
    Carome].” The “Category” box often either is empty or says “Misc.” The “Tag”
    box is empty for many transactions. Some of the entries in that box (such as “[Mr.
    Carome] Contribution”) do indicate how Mr. Rollinger viewed the transaction for
    purposes of the damages calculation, although the entries do not explain why Mr.
    Rollinger reached his conclusions. Other of the entries in that box (such as “[Ms.
    Carome] to Explain”) are not clear. For each transaction, there is also a box labeled
    “Classification,” indicating how Mr. Rollinger categorized the transaction on his
    chart. In some instances, the box refers to a provision of the premarital agreement,
    suggesting without further explanation that the provision was the basis for the
    categorization. In other instances (such as “Payments for Credit Cards” and “Not
    Included in Calculation to Avoid Double Counting”), the rationale for the
    categorization is not specified.
    20
    At no place does the report explain the criteria used to define the various
    categories reflected in the report. The report also does not state what methods or
    sources of information Mr. Rollinger used in preparing the report.
    In the joint pretrial statement, which was filed in May 2019, Ms. Carome
    formally objected to Mr. Rollinger’s report, arguing that the report did not comply
    with Super. Ct. Dom. Rel. R. 26(a)(2)(B). Specifically, Ms. Carome argued that the
    report did not indicate what documents Mr. Rollinger was relying on and did not
    explain Mr. Rollinger’s opinions and his reasons for those opinions. Ms. Carome
    asked that the report be excluded from evidence and that Mr. Rollinger be precluded
    from testifying at trial. In the alternative, Ms. Carome asked the court (1) to require
    Mr. Rollinger to supplement his report with the information required by Super. Ct.
    Dom. Rel. R. 26(a)(2)(B); and (2) to permit Ms. Carome to designate a rebuttal
    expert and submit a rebuttal expert report.
    In the joint pretrial statement, Mr. Carome responded by arguing that Ms.
    Carome’s objection to Mr. Rollinger’s report was belated, the report was adequate,
    and any deficiency in the report did not prejudice Ms. Carome.
    21
    On the first day of trial, Ms. Carome renewed her objection to Mr. Rollinger’s
    report. The trial court overruled Ms. Carome’s objection without explanation.
    Mr. Rollinger testified at length at trial. His expert report was also admitted
    into evidence. During the first three days of his testimony, Mr. Rollinger explained
    (1) the materials he relied on in reaching his conclusions (which included various
    documents, oral conversations with Mr. Carome, and notes kept by Mr. Carome);
    (2) the meaning of various of the terms used in the report (such as “Non-Counted
    Items”); and (3) the methods and reasoning used in reaching the conclusions
    reflected in the report. Ms. Carome cross-examined Mr. Rollinger extensively at
    that point on the bases for his opinions.
    There was a two-month break in the trial, and Ms. Carome then resumed her
    cross-examination of Mr. Rollinger, which extended for parts of two additional days.
    Ms. Carome presented two reports from her own expert, who also testified at
    trial. Ms. Carome’s expert concluded that Ms. Carome was entitled to over $2.6
    million in damages.
    22
    In returning its verdict, the trial court largely accepted the legal framework
    advocated by Mr. Carome, assessing damages by calculating Mr. Carome’s earnings
    between 2013 and November 2017 and then subtracting “authorized subtractions”—
    those falling within the exceptions enumerated in § 1.7(A) of the agreement—as
    well as other amounts that were “necessary expenses” paid by Mr. Carome for the
    benefit of Ms. Carome. The trial court accepted some of Mr. Rollinger’s factual
    conclusions but also made substantial adjustments to Mr. Rollinger’s calculations,
    for a variety of reasons, including that Mr. Rollinger had a “quite flimsy” basis for
    categorizing certain expenses as having been for Ms. Carome’s benefit. The trial
    court ultimately found damages of approximately $440,000 due to Mr. Carome’s
    breach of his obligation to make payments into the joint account.
    On appeal, this court sua sponte remanded the record for the trial court to
    explain its decision to overrule Ms. Carome’s objection to Mr. Rollinger’s report.
    On remand, the trial court concluded that the report complied with the requirements
    of Rule 26(a)(2)(B). Specifically, the trial court stated that the report “sets forth a
    very detailed and comprehensive statement of Mr. Rollinger’s conclusions and sets
    forth minutely specific bases for the opinions.” In the alternative, the trial court
    ruled that any deficiencies in the report were substantially justified and harmless.
    23
    B. Compliance with Super. Ct. Dom. Rel. R. 26(a)(2)(B)
    We review the trial court’s ruling that Mr. Rollinger’s report met the
    requirements of Super. Ct. Dom. Rel. R. 26(a)(2)(B) deferentially, to determine
    whether the trial court acted within the scope of its discretion. See generally, e.g.,
    Weakley v. Burnham Corp., 
    871 A.2d 1167
    , 1179 (D.C. 2005) (“We review
    discovery orders for abuse of discretion.”). See also, e.g., Harmon v. Ga. Gulf Lake
    Charles L.L.C., 
    476 F. App’x 31
    , 36 (5th Cir. 2012) (trial court rulings under Fed.
    R. Civ. P. 26(a)(2)(B) are reviewed for abuse of discretion). Super. Ct. Dom. Rel.
    R. 26(a)(2)(B) is identical to Fed. R. Civ. P. 26(a)(2)(B), so we give weight to cases
    interpreting the federal rule. See generally, e.g., Segreti v. DeIuliis, 
    263 A.3d 441
    ,
    444 (D.C. 2021) (when interpreting Superior Court rule, court looks for guidance to
    federal cases interpreting “substantially identical” federal rule) (internal quotation
    marks omitted).
    As previously noted, Super. Ct. Dom. Rel. R. 26(a)(2)(B) generally requires
    expert reports to include, among other things: “(i) a complete statement of all
    opinions the [expert] will express and the basis and reasons for them; [and] (ii) the
    facts or data considered by the [expert] in forming them.” This court does not appear
    24
    to have issued any opinions interpreting either that language or identical language in
    Super. Ct. Civ. R. 26(a)(2)(B). We therefore consider pertinent federal authority.
    “When interpreting a Superior Court rule, we frequently find guidance in the
    advisory committee’s notes to the corresponding federal rule.” C.R. Calderon
    Constr., Inc. v. Grunley Constr. Co., 
    257 A.3d 1046
    , 1059 (D.C. 2021) (internal
    quotation marks omitted). The language at issue was added to Fed. R. Civ. P.
    26(a)(2) in 1993. See Fed. R. Civ. P. 26(a)(2) advisory committee’s note to 1993
    amendment. The advisory committee explained that the amended rule “imposes an
    additional duty to disclose information regarding expert testimony sufficiently in
    advance of trial that opposing parties have a reasonable opportunity to prepare for
    effective cross examination and perhaps arrange for expert testimony from other
    witnesses.” 
    Id.
     The advisory committee stated that disclosure under the prior rule
    had often been “sketchy and vague.” 
    Id.
     The new rule, in contrast, required “a
    detailed and complete report, stating the testimony the witness is expected to present
    during direct examination, together with the reasons therefor.” 
    Id.
     In other words,
    the report should “set forth the substance of the direct examination.” 
    Id.
    In our view, Mr. Rollinger’s report fell well short of the requirements of
    Super. Ct. Dom. Rel. R. 26(a)(2)(B). The report has no complete sentences, says
    25
    nothing explicit about the sources of information Mr. Rollinger relied upon, does not
    explain the methods Mr. Rollinger used in making calculations, and contains a
    number of unexplained or cryptic terms and categories. Mr. Carome cites no case
    holding that a comparable report was adequate, and we are aware of no such case.
    To the contrary, comparable reports appear to have consistently been found
    inadequate. See, e.g., Martinez v. Sw. Cheese Co., No. CV 12-0660, 
    2013 WL 12180705
    , at *2 (D.N.M. Mar. 4, 2013) (finding expert report inadequate because
    report contained “several pages of charts and calculations without any context” and
    failed to “fully explain[] [the charts’] relevance, their calculations, or their sources”);
    Great White Bear, LLC v. Mervyns, LLC, No. 06 CV 13358, 
    2008 WL 2220662
    , at
    *3 (S.D.N.Y. May 27, 2008) (“A damage figure in an expert report cannot satisfy
    [federal] Rule 26(a)(2)(B) simply by stating a conclusory figure and then attaching
    documents that purportedly support that figure. Rather, the report must supply actual
    calculations with detailed and complete information elucidating how the expert
    arrived at the damage figure.”). See generally, e.g., R.C. Olmstead, Inc. v. CU
    Interface, LLC, 
    606 F.3d 262
    , 271 (6th Cir. 2010) (upholding exclusion of expert
    report that failed to adequately explain expert’s “line of reasoning”; “[e]xpert reports
    must include how and why the expert reached a particular result, not merely the
    expert’s conclusory opinions”) (internal quotation marks omitted).
    26
    In sum, we conclude that the trial court acted outside its discretion in
    concluding that Mr. Rollinger’s report met the requirements of Super. Ct. Dom. Rel.
    R. 26(a)(2)(B).
    C. Harmlessness
    Mr. Carome’s failure to comply with Super. Ct. Dom. Rel. R. 26(a)(2)(B) is
    not a basis for relief if that failure was harmless. Super. Ct. Dom. Rel. R. 37(c)(1)
    (failure to comply with Super. Ct. Dom. Rel. R. 26(a) precludes admission of
    testimony of witness unless failure was “substantially justified or harmless”). See
    generally Super. Ct. Dom. Rel. R. 61 (“Unless justice requires otherwise, no error
    in admitting . . . evidence . . . is ground for granting a new trial, or for vacating,
    modifying or otherwise disturbing a judgment or order. At every stage of the
    proceeding, the court must disregard all errors and defects that do not affect any
    party’s substantial rights.”); Wagner v. Georgetown Univ. Med. Ctr., 
    768 A.2d 546
    ,
    567 (D.C. 2001) (error does not affect substantial rights if court can “say[] with fair
    assurance” that “judgment was not substantially swayed by the error”) (quoting
    Kotteakos v. United States, 
    328 U.S. 750
    , 765 (1946)). The burden of establishing
    harmlessness is on the party who failed to comply with the rule. See, e.g., Wilson v.
    Bradlees of New England, Inc., 
    250 F.3d 10
    , 21 (1st Cir. 2001) (“[I]t is the obligation
    27
    of the party facing sanctions for belated disclosure to show that its failure to comply
    with [Fed. R. Civ. P. 26(a)] was either justified or harmless . . . .”); Hinton v. United
    States, 
    979 A.2d 663
    , 686 (D.C. 2009) (en banc) (under Kotteakos test for
    harmlessness, burden of showing harmlessness “is on the beneficiary of an error”).
    As noted, the trial court ruled on remand that any deficiencies in Mr.
    Rollinger’s report were harmless. It is not entirely clear whether our review of that
    ruling is de novo or deferential. Compare Davis v. United States, 
    564 A.2d 31
    , 42
    (D.C. 1989) (en banc) (in context of constitutional error, court concludes that
    appellate court “owe[s] no deference to the trial court’s views concerning
    harmlessness”), with Prisco v. Stroup, 
    947 A.2d 455
    , 462 (D.C. 2008) (court of
    appeals reviews for abuse of discretion trial court’s determination whether to impose
    sanction under Super. Ct. Dom. Rel. R. 37(c)), and Bresler v. Wilmington Tr. Co.,
    
    855 F.3d 178
    , 190 (4th Cir. 2017) (explaining that, under Fed. R. Civ. P. 37(c)(1),
    “[d]istrict courts are accorded broad discretion in determining whether a party’s
    nondisclosure or untimely disclosure of evidence is substantially justified or
    harmless”) (internal quotation marks omitted). The parties do not explicitly address
    that question, and we need not decide it. Rather, even assuming favorably to Ms.
    Carome that our review is de novo, we conclude that the trial court’s error was
    harmless.
    28
    Our reasoning differs from that of the trial court. In our view, the critical
    points are that Ms. Carome had a full opportunity to cross-examine Mr. Rollinger,
    the trial recessed for approximately two months, and Ms. Carome then had another
    full opportunity to cross-examine Mr. Rollinger. Granting a continuance can be an
    appropriate response to a party’s failure to provide required pretrial discovery. See,
    e.g., Weiner v. Kneller, 
    557 A.2d 1306
    , 1310 n.5 (D.C. 1989) (“Exclusion of
    evidence is a severe sanction. Under [Super. Ct. Civ. R.] 37 the Superior Court may
    avail itself of a lesser sanction, such as a continuance, to allow the surprised party to
    examine the record, possibly resume discovery, and prepare some response to the
    unexpected testimony.”) (citation omitted); cf. Workman v. United States, 
    255 A.3d 971
    , 976 (D.C. 2021) (under Super. Ct. Crim. R. 16, “remedies for [a] discovery
    violation include [the] granting of [a] continuance”). In arguing that she was
    prejudiced by the inadequacies of Mr. Rollinger’s report, Ms. Carome lists various
    actions she could have taken if the report had been adequate, including possibly
    moving to exclude Mr. Rollinger’s report and testimony as unreliable, trying to track
    down original documentation of transactions, and presenting evidence of
    contributions she made to the marriage. Ms. Carome did ultimately move to strike
    Mr. Rollinger’s report and testimony as “subjective, unreliable[,] and riddled with
    errors.” Ms. Carome has not, however, renewed that challenge in this court, instead
    focusing solely on her discovery claim. We see no prejudice to Ms. Carome’s ability
    29
    to challenge the substance of Mr. Rollinger’s testimony and report. As to Ms.
    Carome’s two other assertions of prejudice, the two-month break in the trial was
    seemingly ample to permit Ms. Carome to take whatever steps she wished to take to
    further investigate and respond to Mr. Rollinger’s report and testimony. Cf. Weiner,
    
    557 A.2d at
    1310 n.5 (explaining that continuance can be sufficient remedy to
    address discovery violation).
    We therefore conclude that the trial court’s error was not unfairly prejudicial
    to Ms. Carome, because in the circumstances of this case Ms. Carome had a full
    opportunity to address Mr. Rollinger’s report and testimony.
    VI. Proof of Actual Damages
    Mr. Carome argues that Ms. Carome failed to prove that she suffered actual
    damages as a result of Mr. Carome’s breach of the premarital agreement. We are
    unpersuaded by that argument.
    To remedy a breach of contract, the trial court generally may award the non-
    breaching party expectation damages: the amount that would place the non-
    breaching party in the position the non-breaching party would have had if the
    30
    breaching party had fulfilled its obligations under the contract.         Caesar v.
    Westchester Corp., 
    280 A.3d 176
    , 191 (D.C. 2022). Under the premarital agreement
    in this case, Ms. Carome was entitled to half of the assets contained in the joint
    account upon separation. Agreement § 5.2(A). The trial court thus arguably could
    have awarded Ms. Carome damages in an amount equal to half of the amount that
    Mr. Carome should have contributed to the joint account. The trial court did not
    take that approach, however, instead decreasing the amount of Ms. Carome’s
    damages to reflect payments that the trial court determined Mr. Carome had made
    toward “necessary joint expenses and for Ms. Carome’s benefit.” Ms. Carome has
    not challenged that ruling in this court, and we therefore have no reason to consider
    whether Ms. Carome actually was entitled to more extensive damages than she was
    awarded.
    For his part, Mr. Carome does not present a specific challenge to the trial
    court’s calculation of the amount of the offset to reflect payments Mr. Carome made
    for Ms. Carome’s benefit. Instead, Mr. Carome argues that Ms. Carome should have
    been required to prove specific additional concrete injuries she suffered as a result
    of Mr. Carome’s breach. We see no basis for that argument. See, e.g., Caesar, 280
    A.3d at 191 (actual costs suffered by non-breaching party “of no consequence”
    where non-breaching party was properly awarded expectation damages).
    31
    In sum, (1) we affirm the trial court’s ruling that Mr. Carome’s obligation to
    contribute to the joint account ended on the date of separation; (2) we reverse the
    trial court’s ruling that Mr. Carome was entitled to deduct payments made to the
    defined-benefit plan in years when Mr. Carome did not contribute to the joint
    account; (3) we affirm the trial court’s ruling that Mr. Carome’s earnings under the
    agreement included a prorated share of Mr. Carome’s 2017 law-firm compensation;
    (4) we hold that the trial court acted outside its discretion in concluding that Mr.
    Rollinger’s report complied with the requirements of Super. Ct. Dom. Rel. R.
    26(a)(2)(B); (5) we hold that that error was harmless; and (6) we uphold the trial
    court’s ruling that Ms. Carome was not required to prove actual costs she suffered
    as a result of Mr. Carome’s breach of the agreement, beyond the loss of the financial
    contributions Mr. Carome was required to make under the agreement. We therefore
    vacate the judgment and remand the case to the trial court for further proceedings.
    So ordered.
