    Law & Justice, Inc. (Appleseed) and Group Hospitalization and Medical Services,
    Inc. (GHMSI) seek review of orders of respondent, the District of Columbia
    Department of Insurance, Securities and Banking (DISB), determining that
    GHMSI’s 2011 surplus was excessive, that the excess surplus attributable to the
    District was approximately $50 million, and that GHMSI was required to distribute
    its excess surplus in the form of rebates to eligible subscribers of GHMSI. We
    remand for further proceedings.
    I. Factual and Procedural History
    This matter has previously been before this court. D.C. Appleseed Ctr. for
    Law & Justice, Inc. v. District of Columbia Dep’t of Ins., Sec., & Banking (Appleseed
    I), 
    54 A.3d 1188
    (D.C. 2012). The following background material is taken in
    significant part from our prior opinion, supplemented and revised as necessary to
    reflect subsequent developments.
    3
    A. GHMSI
    GHMSI is the successor to Group Hospitalization, Inc., a nonprofit
    organization created in 1939 by congressional charter to provide health-care services
    and medical insurance. Pub. L. No. 76-395, §§ 3, 8, 53 Stat. 1412, 1413-14 (1939);
    Pub. L. No. 98-493, § 1, 98 Stat. 2272 (1984). Organized as a “charitable and
    benevolent institution,” GHMSI “shall be conducted for the benefit of [its] certificate
    holders.” Pub. L. No. 76-395, §§ 3, 8, 53 Stat. 1413-14. GHMSI conducts business
    in the District, Maryland, and Virginia.
    Although GHMSI initially was not subject to the statutes regulating the
    business of insurance in the District, Congress amended GHMSI’s charter in 1993
    to domicile GHMSI in the District and place GHMSI under the District’s regulatory
    authority. Pub. L. No. 103-127, § 138, 107 Stat. 1336, 1349 (1993). Such regulatory
    authority includes review and approval of GHMSI’s proposed health-insurance
    premium rates. D.C. Code § 31-3311.01 et seq. (2012 Repl.). D.C. law also requires
    GHMSI to maintain certain risk-based capital levels and to report those levels on an
    annual basis to the DISB Commissioner. D.C. Code § 31-3451.01 et seq. (2019
    Supp.).
    4
    In 1998, GHMSI affiliated with CareFirst of Maryland, Inc. GHMSI and
    CareFirst of Maryland jointly own CareFirst BlueChoice, Inc. GHMSI is a licensee
    of the Blue Cross Blue Shield Association (BCBSA).
    B. The Medical Insurance Empowerment Amendment Act
    In 2009, the Council of the District of Columbia enacted the Medical
    Insurance Empowerment Amendment Act (MIEAA). D.C. Law 17-369, 56 D.C.
    Reg. 1346 (Feb. 13, 2009) (codified as amended at D.C. Code § 31-3501 et seq.
    (2012 Repl. & 2019 Supp.)). The MIEAA authorizes the Commissioner of DISB to
    determine whether a medical-services corporation’s surplus is “excessive” and to
    order that any excess surplus be reinvested in “community health.” D.C. Code
    § 31-3506(e), (g)(1) (2019 Supp.).       Specifically, the MIEAA and subsequent
    amendments added a new subsection to D.C. Code § 31-3506, which now states in
    relevant part:
    The Commissioner may, on an annual basis, and shall, on
    a basis no less frequently than every 3 years, review the
    portion of the surplus of the corporation that is attributable
    to the District and may issue a determination as to whether
    the surplus is excessive. Any such review shall be
    undertaken in coordination with the other jurisdictions in
    which the corporation conducts business. The surplus may
    be considered excessive only if:
    5
    (1) The surplus is greater than the appropriate risk-based
    capital requirements as determined by the Commissioner
    for the immediately preceding calendar year; and
    (2) After a hearing, the Commissioner determines that the
    surplus is unreasonably large and inconsistent with the
    corporation’s obligation under § 31-3505.01.
    D.C. Code § 31-3506(e); see also D.C. Law 18-104, 56 D.C. Reg. 9182 (Dec. 4,
    2009); D.C. Law 19-171, 59 D.C. Reg. 6190 (June 1, 2012).
    D.C. Code § 31-3505.01 requires GHMSI and similar entities to “engage in
    community health reinvestment to the maximum feasible extent consistent with
    financial soundness and efficiency.” The MIEAA also provides that “[i]n
    implementing the provisions of the [MIEAA], the Commissioner shall consider the
    interests and needs of the jurisdictions in the corporation’s service area.” D.C. Code
    § 31-3506.01(b) (2012 Repl.).
    C. Surplus Requirements and Excess Surplus Determination
    GHMSI is required to maintain a surplus of capital to cover its projected risk,
    development costs, and growth. D.C. Code § 31-3451.01 et seq. The National
    Association of Insurance Commissioners (NAIC) has developed widely accepted
    risk-based capital (RBC) formulae to determine the minimum amount of capital an
    6
    insurer should hold to support its business operations. The baseline figure in the
    RBC formula is the authorized control level (ACL), which is a reference value that
    accounts for the insurer’s size, structure, and volume of risk. The District of
    Columbia has adopted statutory minimum requirements for insurance companies’
    surplus levels, expressed as an RBC-ACL ratio. D.C. Code §§ 31-2001 to -2013
    (2012 Repl. & 2019 Supp.).
    If a health insurer’s RBC-ACL ratio falls under certain statutory levels,
    company or regulatory action is authorized or required. D.C. Code §§ 31-3451.01
    to .06. For example, if an insurer’s surplus falls below 200% RBC-ACL, the insurer
    must submit a plan to the Commissioner identifying the conditions that led to that
    event and proposing corrective actions to bring the surplus up to a safer level. D.C.
    Code §§ 31-3451.01(6), .03. If an insurer’s surplus falls to lower RBC-ACL levels,
    the Commissioner is authorized or obligated take increasingly corrective actions.
    D.C. Code §§ 31-3451.04 to .06. Additionally, as a licensee of BCBSA, GHMSI is
    subject to contractual RBC-ACL standards set by BCBSA. Specifically, early-
    warning monitoring is triggered if a BCBSA licensee’s surplus falls below 375%
    RBC-ACL, and the licensee must take certain corrective actions. The Commissioner
    is required to consider NAIC’s RBC requirements and BCBSA’s capital
    7
    requirements in determining whether a medical-services corporation’s surplus is
    excessive. 26A DCMR § 4601.4 (2019).
    Regulations promulgated by DISB in 2009 establish further procedures for the
    Commissioner’s review of medical-services corporations’ surplus. 26A DCMR
    § 4600 et seq. (2019). The regulations require medical-services corporations such
    as GHMSI to file an annual financial report with DISB detailing “the company’s
    surplus and examin[ing] whether the company’s surplus is considered excessive
    under the [MIEAA].” 26A DCMR § 4601.1. If the Commissioner preliminarily
    determines that the company’s surplus is excessive, the regulations require a public
    hearing “to determine whether the company’s surplus is excessive and unreasonably
    large.” 26A DCMR § 4601.5. If the Commissioner makes a final determination that
    a company’s surplus that is attributable to the District is excessive, the
    Commissioner must order the company to submit a plan for dedication of the excess
    surplus to community-health reinvestment.       D.C. Code § 31-3506(g)(1); 26A
    DCMR § 4603.1.
    8
    D. DISB’s 2008 Surplus Determination and Appleseed I Decision
    In 2010, the Commissioner concluded that GHMSI’s 2008 year-end surplus
    was neither unreasonably large nor excessive. Appleseed, which is a consumer of
    health insurance, a subscriber of GHMSI, and an organization with goals including
    improving access to healthcare in the District, challenged the Commissioner’s
    ruling. Appleseed 
    I, 54 A.3d at 1201
    , 1210. On review, this court held, in pertinent
    part, that the Commissioner’s analysis of GHMSI’s 2008 surplus was incomplete,
    because that analysis considered whether GHMSI’s surplus was unreasonably large
    without considering whether the surplus was inconsistent with GHMSI’s statutory
    obligation to engage in community-health reinvestment. 
    Id. at 1212-15.
    We
    emphasized that the Commissioner, when deciding whether an insurer’s surplus is
    excessive, must keep in mind both statutory goals: (A) the insurer’s financial
    soundness and (B) maximization of community-health reinvestment. 
    Id. We also
    concluded that the Commissioner’s order did not adequately explain the
    Commissioner’s findings and conclusions. 
    Id. at 1218-19.
    We remanded the case
    for further proceedings, including a redetermination as to whether GHMSI’s surplus
    was excessive, with more complete explanation of the Commissioner’s reasoning.
    
    Id. at 1220-21.
                                              9
    E. Subsequent DISB Orders and Procedural History
    On remand, the Commissioner determined that further review of the 2008
    surplus would be moot and began the review process for GHMSI’s 2011 year-end
    surplus, the most recent year for which surplus information was available at the time.
    DISB retained an actuarial firm and a financial-analysis firm to assist in the surplus
    review. GHMSI and Appleseed also retained actuarial consultants. As part of the
    review process, Appleseed, GHMSI, and their consultants met with DISB’s
    consultants and submitted written reports and briefs on whether GHMSI’s 2011
    surplus was excessive and what portion of any excess surplus was attributable to the
    District.   In June 2014, DISB held a public hearing.        After the hearing, the
    Commissioner received statements from the Maryland Insurance Commissioner and
    the Virginia State Corporation Commission’s Bureau of Insurance.
    In December 2014, the Commissioner issued a decision and order with respect
    to GHMSI’s 2011 surplus. The order concluded that (1) GHMSI’s appropriate level
    of surplus as of the end of 2011 was 721% RBC-ACL (approximately $695.9
    million); (2) GHMSI’s actual surplus at the end of 2011 was 998% RBC-ACL
    (approximately $963.6 million), meaning that GHMSI’s excess surplus was
    approximately $267.7 million; and (3) 21% of GHMSI’s excess surplus was
    10
    attributable to the District. GHMSI took the position that it had no excess surplus
    attributable to the District and had already undertaken community-health
    reinvestment beyond what the Commissioner’s order required. GHMSI therefore
    did not submit a plan for additional distribution of excess surplus.              The
    Commissioner disagreed and directed GHMSI to disburse the excess surplus
    attributable to the District (approximately $50 million) by issuing rebates to eligible
    subscribers.
    II. Analysis
    The parties raise numerous challenges to the Commissioner’s ruling. Because
    we find some of those challenges persuasive, we remand for further proceedings.
    A. Standard of Review
    On questions of statutory interpretation, we first look to see whether the
    statutory language at issue is “plain and admits of no more than one meaning.”
    Peoples Drug Stores, Inc. v. District of Columbia, 
    470 A.2d 751
    , 753 (D.C. 1983)
    (en banc) (internal quotation marks omitted). We will give effect to the plain
    meaning of a statute “when the language is unambiguous and does not produce an
    11
    absurd result.” McNeely v. United States, 
    874 A.2d 371
    , 387 (D.C. 2005) (internal
    quotation marks omitted). “We may also look to the legislative history to ensure
    that our interpretation is consistent with legislative intent.” Thomas v. Buckley, 
    176 A.3d 1277
    , 1281 (D.C. 2017) (internal quotation marks omitted). If a statute is
    ambiguous, “we will defer to an agency’s reasonable interpretation of the statute it
    administers.” Appleseed 
    I, 54 A.3d at 1211
    .
    Under the D.C. Administrative Procedure Act, this court will uphold an
    agency’s decision unless the decision is arbitrary, capricious, an abuse of discretion,
    or otherwise not in accordance with the law. D.C. Code § 2-510(a)(3)(A) (2016
    Repl.). “The Commissioner must make factual findings on all material contested
    issues, the findings must be supported by substantial evidence on the record, and the
    conclusions must flow rationally from the findings.” Appleseed 
    I, 54 A.3d at 1216
    .
    The Commissioner’s order must also state the basis of its ruling in sufficient detail
    and be fully and clearly explained, so as to allow “for meaningful judicial review of
    and deference to the agency’s decision.” 
    Id. Although agency
    determinations based
    upon highly complex and technical matters are entitled to great deference, “[t]he
    more technical and complex the subject matter, the more explanation the agency
    ought to provide for its decision.” 
    Id. at 1217.
                                             
    12 Barb. 2015
    Congressional Amendments
    In 2015, Congress amended GHMSI’s charter to provide that GHMSI “shall
    not divide, attribute, distribute, or reduce its surplus pursuant to any statute,
    regulation, or order of any jurisdiction without the express agreement of the District
    of Columbia, Maryland, and Virginia—(1) that the entire surplus of the corporation
    is excessive; and (2) to any plan for reduction or distribution of surplus.” Pub. L.
    No. 114-113, § 747(a), 129 Stat. 2242, 2486 (2015). Relying on that amendment,
    Virginia appears to argue that the Commissioner was flatly precluded from requiring
    GHMSI to distribute or reduce its surplus without the express agreement of
    Maryland and Virginia. By its plain language, however, the 2015 amendment does
    not apply to the present dispute about GHMSI’s 2011 surplus. The 2015 amendment
    “shall apply with respect to the surplus of [GHMSI] for any year after 2011.”
    § 747(b), 129 Stat. at 2486 (emphasis added). It is true that requiring GHMSI to
    provide a rebate relating to its 2011 surplus would likely have an impact on the size
    of GHMSI’s surplus in years after 2011. But Congress was no doubt aware of that
    fact and nevertheless made the 2015 amendments inapplicable to distribution of the
    2011 surplus. We have no basis to look behind Congress’s clearly expressed
    decision. See CareFirst, Inc. v. Taylor, 
    235 F. Supp. 3d 724
    , 744-45 (D. Md. 2017)
    13
    (plain language of 2015 amendment required conclusion that 2015 congressional
    amendment did not apply to determination of GHMSI’s 2011 surplus).
    C. Coordination
    As previously noted, D.C. Code § 31-3506(e) authorizes the Commissioner to
    “review the portion of the surplus of [GHMSI] that is attributable to the District and
    [to] issue a determination as to whether the surplus is excessive.” Section 31-
    3506(e) further requires that this review “be undertaken in coordination with the
    other jurisdictions in which [GHMSI] conducts business.” GHMSI and Virginia
    argue that the Commissioner failed to adequately coordinate the review of GHMSI’s
    surplus with Virginia and Maryland. We agree. We conclude, however, that in some
    respects this issue was not properly presented to the Commissioner, which affects
    the scope of relief we grant.
    1. Procedural background
    The Commissioner’s review of GHMSI’s 2011 surplus began in 2012. During
    the period up to the June 2014 hearing, the Commissioner and DISB staff apparently
    communicated with Maryland and Virginia insurance commissioners and their staff,
    14
    including advising them of the surplus-review hearing and soliciting their
    participation. As far as we have been able to determine, at no point during that
    period did either Virginia or Maryland object that the Commissioner was failing to
    adequately coordinate with them. After the hearing, both Virginia and Maryland
    filed brief statements that raised no objection about lack of coordination and that
    thanked DISB for the opportunity to comment.
    During the period up to the June 2014 hearing, GHMSI did encourage DISB
    in general terms to coordinate with Maryland and Virginia to help ensure that
    GHMSI would not be subject to conflicting obligations. GHMSI did not, however,
    raise any specific objection to the manner in which DISB was coordinating with
    Virginia and Maryland.       At the hearing, a witness for GHMSI advocated
    coordination through “direct communication” but did not assert that such
    communication had been lacking.
    It appears that the first concrete objection on the ground of inadequate
    coordination was not raised until after the December 2014 order, over two years after
    the proceeding began. Specifically, GHMSI for the first time argued that the
    Commissioner should reopen the proceedings and invite Maryland and Virginia to
    participate in a consolidated proceeding. Even after December 2014, the Virginia
    15
    Bureau of Insurance did not object to a lack of coordination, instead issuing a report
    stating that it recommended that Virginia take a more active role in future
    proceedings.
    2. Analysis
    We hold that any objection to the Commissioner’s failure to adequately
    coordinate with Virginia and Maryland before the December 2014 order was not
    properly presented. “In the absence of exceptional circumstances, a reviewing court
    will refuse to consider contentions not presented before the administrative agency at
    the appropriate time.” District of Columbia Hous. Auth. v. District of Columbia
    Office of Human Rights, 
    881 A.2d 600
    , 611 (D.C. 2005) (internal quotation marks
    omitted). “One principal reason for the rule that procedural objections must be
    timely made is to give the tribunal and opposing parties the opportunity to correct or
    controvert the purported defect when it is still possible to do so.” 
    Id. We see
    no
    justification for requiring the Commissioner to begin this proceeding anew based on
    an objection that was not raised until over two years into the proceeding and that
    could have been raised far earlier. Cf., e.g., District of Columbia Gen. Hosp. v.
    District of Columbia Office of Emp. Appeals, 
    548 A.2d 70
    , 75 (D.C. 1988) (refusing
    to permit party to belatedly challenge substitution of hearing examiner; “A contrary
    16
    rule . . . would only countenance and encourage unacceptable inefficiency in the
    administrative process.”) (internal quotation marks omitted).
    On the other hand, GHMSI did eventually object on the ground of inadequate
    coordination, and that objection sufficed to preserve the issue with respect to
    subsequent proceedings. Moreover, because we are remanding on other issues, the
    obligation to coordinate is relevant to proceedings on remand. We therefore must
    address on the merits the nature of the Commissioner’s obligation to coordinate.
    As previously noted, § 31-3506(e) requires that the Commissioner’s review
    of GHMSI’s surplus “be undertaken in coordination with the other jurisdictions in
    which [GHMSI] conducts business.” The purposes of that provision seem obvious
    and do not appear to be disputed: (1) to ensure that the Commissioner gets the
    benefit of the knowledge and experience of the other jurisdictions that are regulating
    GHMSI; (2) to ensure that the Commissioner takes into account the needs and
    interests of subscribers and regulators in the other jurisdictions; and (3) to try to
    reduce the extent to which GHMSI is subjected to conflicting regulations in different
    jurisdictions.   For several reasons, we agree with GHMSI and Virginia that
    coordination requires more than simply soliciting and considering input from
    Virginia and Maryland.
    17
    First, we place substantial weight on the dictionary definitions of
    “coordination” and the corresponding verb “coordinate.”           Cf. generally, e.g.,
    O’Rourke v. District of Columbia Police & Firefighters’ Ret. & Relief Bd., 
    46 A.3d 378
    , 383 (D.C. 2012) (“The first step in construing a statute is to read the language
    of the statute and construe its words according to their ordinary sense and plain
    meaning.”) (internal quotation marks omitted).       Those definitions consistently
    contemplate more than mere consultation.          See, e.g., Webster’s Third New
    International Dictionary 501 (2012) (defining “coordinate,” inter alia, as to
    “regulate and combine in harmonious action”); Oxford Dictionary of English 384
    (3d ed. 2010) (defining “coordinate” as to “bring the different elements of (a
    complex activity or organization) into a harmonious or efficient relationship” or to
    “negotiate with others in order to work together effectively”).
    Second, other courts construing the terms “coordinate” and “coordination”
    have understood them to mean more than consultation. See Cal. Native Plant Soc’y
    v. City of Rancho Cordova, 
    91 Cal. Rptr. 3d 571
    , 602 (Ct. App. 2009)
    (“‘[C]oordination’ implies some measure of cooperation that is not achieved by
    merely asking for and considering input or trying to work together.”); In re Water
    Use Permit Applications, 
    9 P.3d 409
    , 501 (Haw. 2000) (requirement of
    18
    “coordination” “is a call for cooperation and mutual accommodation”; “The
    objectives of the Commission and the counties will not always converge. To the
    extent that their respective functions and duties permit, however, the Commission
    and counties should be seeking common ground.”). We are aware of one decision
    that points in the opposite direction, but that decision does so without analysis and
    we do not find that decision persuasive, particularly given the other considerations
    present in the context of the MIEAA. Bienz v. City of Dayton, 
    566 P.2d 904
    , 916-
    917 (Or. Ct. App. 1977) (city complied with coordination requirement “by actively
    seeking and considering comments and recommendations from various affected
    state and local agencies”).
    Third, the coordination requirement was added to the MIEAA in a 2009
    amendment. D.C. Law 18-104, § 2(c)(1), 56 D.C. Reg. 9182, 9184 (Dec. 4, 2009).
    At the time of that amendment, the MIEAA already required that, “[i]n
    implementing the provisions of the [MIEAA], the Commissioner shall consider the
    interests and needs of the jurisdictions in the corporation’s service area.” D.C. Code
    § 31-3506.01(b) (2009 Repl.). The coordination requirement thus would ordinarily
    be read to impose obligations that run beyond mere consideration of interests. See
    generally, e.g., Stevens v. District of Columbia Dep’t of Health, 
    150 A.3d 307
    , 315-
    16 (D.C. 2016) (“One of the most basic interpretive canons is that a statute should
    19
    be construed so that effect is given to all its provisions, so that no part will be
    inoperative or superfluous, void or insignificant.”) (brackets and internal quotation
    marks omitted).
    Fourth, as noted, the coordination requirement is obviously intended to serve
    the purpose of minimizing the extent to which GHMSI and similar entities are
    subjected to conflicting regulation in different jurisdictions. The importance of
    avoiding such conflicting regulation if possible is widely recognized. See, e.g., CTS
    Corp. v. Dynamics Corp. of Am., 
    481 U.S. 69
    , 88-89 (1987) (noting adverse effects
    that may arise from subjecting activities to inconsistent regulation). Any reasonable
    interpretation of the coordination requirement must give appropriate weight to that
    consideration.
    We acknowledge our obligation to defer to the Commissioner’s reasonable
    interpretations of statutory provisions that the Commissioner administers.
    Appleseed 
    I, 54 A.3d at 1211
    . For the foregoing reasons, however, we conclude that
    the coordination requirement cannot reasonably be understood to require mere
    consultation. See Cal. Native Plant 
    Soc’y, 91 Cal. Rptr. 3d at 602-03
    (rejecting as
    unreasonable interpretation of “coordination” to mean “consultation”). It remains,
    though, to determine what more is required.
    20
    GHMSI and Virginia initially appeared to contend that the coordination
    requirement should be construed to preclude the Commissioner from acting without
    the agreement of both Virginia and Maryland. Both GHMSI and Virginia disavowed
    that position at oral argument, however. We agree that coordination does not require
    unanimous agreement. See Cal. Native Plant 
    Soc’y, 91 Cal. Rptr. 3d at 603
    (“[W]e
    do not read this ‘coordination’ requirement as requiring the City to subordinate itself
    to state and federal agencies by implementing their comments and taking their
    direction.”) (brackets and internal quotation marks omitted).
    DISB argues that the Commissioner’s obligation is to coordinate only with
    respect to the process of review, not with respect to any of the actual determinations
    as to whether GHMSI’s surplus is excessive or what portion of the excess surplus is
    attributable to the District. We disagree. As a textual matter, it seems strained at
    best to treat the Commissioner’s determinations as distinct from, rather than the
    culmination of, the Commissioner’s review. As a practical matter, reading the
    Commissioner’s coordination obligation so narrowly would frustrate the obvious
    purpose of requiring coordination. See generally, e.g., Rouse v. United States, 
    391 A.2d 790
    , 791 (D.C. 1978) (“As between an interpretation that will effectuate the
    21
    obvious intent of our statute and one that will largely frustrate that intent, we
    unhesitating[ly] adopt the former.”) (brackets and internal quotation marks omitted).
    On a related topic, DISB argues that the Commissioner’s obligation to
    “consider the interests and needs of the jurisdictions in [GHMSI]’s service area”
    applies only to determining how to reinvest excess surplus. The plain language of
    the applicable provision makes clear, however, that this requirement applies to all of
    the Commissioner’s decisions “[i]n implementing the provisions of the [MIEAA].”
    D.C. Code § 31-3506.01(b).
    We turn to what the coordination requirement more concretely demands in the
    current setting. In our view, the coordination requirement obliges the Commissioner
    to try to work together with Maryland and Virginia with an eye towards agreement
    if that is feasible and permissible under applicable law. That may include, but is not
    necessarily limited to: (a) inviting the corresponding regulators in Maryland and
    Virginia to participate in a joint proceeding; (b) soliciting on-the-record input from
    the corresponding regulators, including where appropriate by directing specific
    questions to them; (c) giving appropriate weight to the important interest in, to the
    extent reasonably possible, avoiding inconsistent regulation of GHMSI; and (d) if
    the Commissioner reaches conclusions that differ from those reached by
    22
    corresponding regulators, explaining why (i) principles of District law require that
    result or (ii) other important considerations outweigh the interest in uniform
    regulation.
    We note, however, that it takes at least two to coordinate. Neither Virginia
    nor Maryland imposes a statutory obligation on its regulators to coordinate (or even
    consult) with the District in the regulation of GHMSI. To the contrary, Virginia and
    Maryland have each enacted a statute prohibiting GHMSI from complying with
    DISB orders requiring reduction or distribution of its surplus without the respective
    approval of Virginia or Maryland. Va. Code Ann. § 38.2-4229.2(D) (West 2019);
    Md. Code Ann., Ins. § 14-124(a)(6) (West 2019). Each also issued an administrative
    order to the same effect. Relatedly, with respect to GHMSI’s stated interest in
    avoiding inconsistent regulation, we note that GHMSI specifically asked Virginia
    and Maryland to issue those administrative orders, which directly conflict with the
    Commissioner’s orders.       The Commissioner may appropriately take these
    circumstances into account in determining the weight to be given to the interest in
    uniform regulation of GHMSI.
    We flag a remaining issue for the Commissioner to consider on remand. DISB
    suggests in its briefs and suggested at oral argument that some of the
    23
    Commissioner’s consultations with Maryland and Virginia were not placed on the
    record. In general, formal agency adjudications such as this must be based on
    matters of record. See, e.g., Fair Care Found. v. District of Columbia Dep’t of Ins.
    & Sec. Regulation, 
    716 A.2d 987
    , 996 (D.C. 1998) (“An agency is required to
    maintain an official record in every contested case, and is prohibited from issuing
    any decision or order in such a case except upon consideration of such exclusive
    record.”) (footnote and internal quotation marks omitted).        On remand, the
    Commissioner should consider this principle in determining the manner of its
    coordination with Maryland and Virginia.
    D. Commerce Clause
    Virginia briefly argues that the Commissioner’s order violates the Commerce
    Clause, because the order reduces GHMSI’s overall surplus, thereby burdening
    GHMSI subscribers in Virginia and Maryland. Framed at that level of generality,
    Virginia’s argument is unpersuasive, particularly given that Congress domiciled
    GHMSI in the District and provided the District with regulatory authority over
    GHMSI’s activities. Pub. L. No. 103-127, § 138, 107 Stat. 1349; cf. generally, e.g.,
    Sprint Commc’ns Co. v. Kelly, 
    642 A.2d 106
    , 114 (D.C. 1994) (whether one state’s
    tax on company doing business in multiple states violates Commerce Clause
    24
    depends on whether tax “(1) applies to an activity with a substantial nexus to the
    taxing state; (2) is fairly apportioned; (3) discriminates against interstate commerce;
    and (4) is fairly related to services or benefits provided by the states”).
    Virginia has not in this case presented a more specific challenge to the
    Commissioner’s orders, based on a concrete analysis of those orders and other
    particular circumstances that might be relevant to whether the orders impermissibly
    discriminate against residents of Maryland or Virginia or otherwise are
    impermissible under the Commerce Clause. We therefore do not address that issue.
    See, e.g., Graham v. United States, 
    12 A.3d 1159
    , 1167 n.10 (D.C. 2011) (“Where a
    party generally raises an issue on appeal without supporting argument, we deem [the
    issue] abandoned.”). We do note, however, that GHMSI has raised a Commerce
    Clause claim in a pending federal case that GHMSI brought against DISB and the
    corresponding Virginia and Maryland regulators. CareFirst, Inc. v. Taylor, No.
    1:16-cv-02656 (D. Md. filed July 22, 2016).
    E. Confidence Level
    In determining whether GHMSI’s 2011 surplus was excessive, the
    Commissioner tried to assess the future risks that GHMSI faced. The Commissioner
    25
    analyzed those risks in terms of a specific benchmark: the likelihood that GHMSI
    would fall below 200% of RBC-ACL in the next three years. The Commissioner
    tried to determine what level of surplus would provide a sufficient assurance that
    GHMSI would not fall below that benchmark. The parties do not dispute that general
    approach. The parties do disagree about the appropriate level of assurance, also
    called a confidence level.     Appleseed argues that the appropriate three-year
    confidence level is not higher than 90%, i.e., that GHMSI’s 2011 surplus needed to
    be no larger than would create a 90% probability that GHMSI would remain above
    the 200% RBC-ACL benchmark in the following three years. GHMSI argues that
    the appropriate three-year confidence level is 98%.            DISB defends the
    Commissioner’s choice of a 95% three-year confidence level. We uphold the
    Commissioner’s choice of a 95% confidence level.
    In selecting a 95% confidence level, the Commissioner emphasized the
    adverse consequences of falling below the 200% benchmark. Specifically, the
    Commissioner found that dropping below that benchmark:             (1) is generally
    understood as a sign of serious financial problems; (2) would permit the Blue Cross
    Blue Shield Association to revoke GHMSI’s licensing agreement, causing some
    GHMSI subscribers to be reassigned to other providers and all GHMSI subscribers
    to lose the benefits of full access to the Blue Cross Blue Shield network; (3) would
    26
    likely cause significant concerns among GHMSI subscribers and policyholders,
    possibly leading subscribers to leave GHMSI; and (4) given GHMSI’s dominance
    in the District’s market, would cause extreme distress in the District’s health-
    insurance market. The Commissioner also found, with adequate support in the
    record, that it would be difficult for GHMSI to rebuild its surplus.
    The Commissioner concluded, however, that a 95% confidence level was high
    enough to be “consistent with financial soundness and efficiency.”              The
    Commissioner explained that falling below the 200% benchmark would not itself
    cause GHMSI to be insolvent and would trigger regulatory oversight and other
    ameliorative responses by GHMSI. The Commissioner further reasoned that picking
    a confidence level higher than 95% would not give effect to the statutory obligation
    to maximize community-health reinvestment, because a higher confidence level
    would cause GHMSI to “accumulate surplus at a level that [would be] inefficient or
    unnecessary for financial soundness.” Conversely, the Commissioner concluded
    that picking a confidence level as low as 90%, the figure Appleseed advocated,
    “could jeopardize [GHMSI’s] financial soundness.”
    In Appleseed I, we explained that “a proper surplus determination under the
    MIEAA requires simultaneous consideration of the requirement to engage in
    27
    community reinvestment to the maximum feasible extent consistent with financial
    soundness and 
    efficiency.” 54 A.3d at 1218-19
    (internal quotation marks omitted).
    We further explained that, “[a]s to the specification of how surplus and community
    reinvestment are to be calculated and balanced, we defer to the agency’s reasonable
    discretion in light of its expertise in this subject matter.” 
    Id. at 1215.
    We conclude
    that the Commissioner’s selection of a 95% confidence level in this case reasonably
    balanced the competing considerations of financial soundness and community-
    health reinvestment. We also conclude that the Commissioner adequately explained
    his decision. We are not persuaded by the arguments to the contrary.
    First, GHMSI argues that a 95% confidence level was not supported by the
    evidence. To the contrary, there was evidence in the record that supported use of a
    95% confidence level. In any event, under Appleseed I, the determination of a
    confidence level is not a purely factual decision to be based exclusively on actuarial
    opinions or evidence of industry practice, though such information is certainly
    relevant. Rather, determination of a confidence level requires a policy judgment,
    based on a balancing of the pertinent risks and benefits.
    Second, Appleseed argues that 2% or 5% risks are necessarily too attenuated
    to justify GHMSI’s holding of surplus. We do not agree. A relatively small risk can
    28
    reasonably be viewed as substantial if the gravity of the harm is sufficiently great.
    See, e.g., Onishea v. Hopper, 
    171 F.3d 1289
    , 1297 (11th Cir. 1999) (“[W]hen the
    adverse event is the contraction of a fatal disease, the risk of transmission can be
    significant even if the probability of transmission is low: death itself makes the risk
    significant.”) (internal quotation marks omitted). We thus see no categorical bar to
    adopting a confidence level of 95%.
    Third, the parties dispute the proper mathematical calculation of the long-term
    risks associated with picking a particular three-year confidence level. An expert
    retained by DISB stated that under a 90% three-year confidence level GHMSI’s
    surplus falling below the 200% benchmark “would be expected, statistically, to
    occur once every 10 years.” According to Appleseed’s expert, making certain
    simplifying assumptions, a 90% three-year confidence level would mean that
    GHMSI’s surplus would be expected to fall below the 200% benchmark once every
    thirty years. We need not resolve that dispute. The Commissioner’s December 2014
    order does not explicitly adopt either expert’s view, stating only that a 90%
    confidence level would mean “a one-in-ten chance of surplus falling below 200%
    RBC-ACL.” That statement is indisputably accurate as it relates to the single three-
    year period directly at issue.
    29
    F. Range v. Fixed Number
    The Commissioner concluded that, in order to ensure that GHMSI’s surplus
    would not fall below the 200% benchmark at a 95% three-year confidence level,
    GHMSI needed a 2011 surplus of 721% RBC-ACL, i.e., approximately $700
    million. The Commissioner thus determined that surplus above that amount was
    excessive. GHMSI argues that the Commissioner erred in picking a fixed number
    rather than a range, because a range is necessary to account for the “imprecision of
    surplus analysis and the variability of surplus.” GHMSI also argues that the
    Commissioner did not adequately explain the reasoning behind its decision to pick
    a fixed number rather than a range. We uphold the Commissioner’s ruling on this
    point.
    As we have explained, the Commissioner is charged under the MIEAA with
    determining whether GHMSI held excess surplus in 2011 that should be reinvested
    in community health. The Commissioner acted reasonably in using a fixed number
    rather than a range in determining the amount of surplus that was appropriate for
    GHMSI in 2011. Like other decisionmakers, administrative agencies are often
    required to make specific decisions in complicated contexts based on predictions or
    other estimates. Cf., e.g., Florida v. Georgia, 
    138 S. Ct. 2502
    , 2514 (2018)
    30
    (“Reliance on reasonable predictions of future conditions is necessary.”) (internal
    quotation marks omitted). Although agencies may in some circumstances respond
    to such uncertainty by picking a range rather than a fixed number, the predominant
    approach is “the traditional ‘pick-a-point’ methodology.” Ill. Bell Tel. Co. v. Ill.
    Commerce Comm’n, 
    561 N.E.2d 426
    , 433 (Ill. App. Ct. 1990). We see no error in
    the Commissioner’s decision to apply the traditional approach in the current setting.
    We are also satisfied with the Commissioner’s explanation that if the Commissioner
    established a range rather than a target, GHMSI might end up holding excess surplus.
    GHMSI argues, however, that given the uncertainties involved it is
    unreasonable to treat GHMSI as having “violat[ed] the MIEAA” simply because its
    2011 surplus was above the fixed number calculated by the Commissioner. We
    disagree. The Commissioner’s determination that GHMSI held excessive surplus
    did not trigger any punitive consequences. Rather, it simply provided a basis for the
    Commissioner’s later order requiring that GHMSI reinvest the excess surplus
    attributable to the District in community health. We see no unfairness in imposing
    such a consequence as a result of such a determination.
    31
    G. Equity Portfolio
    GHMSI’s earnings from its portfolio of equity investments constitute a
    significant part of GHMSI’s overall revenue, and gains and losses on those
    investments could substantially affect GHMSI’s future financial situation.
    Accordingly, the actuaries attempted to predict the range of possible future gains and
    losses on those investments and to assess the impact of such possible gains and losses
    on GHMSI’s overall financial condition. Before the Commissioner, Appleseed
    repeatedly argued that the experts retained by DISB and GHMSI were committing
    an error in their calculations on that issue, which had the effect of exaggerating the
    effect of potential equity-portfolio losses on GHMSI’s overall revenue. GHMSI’s
    expert denied that such an error had been committed. The Commissioner adopted
    the approach taken by DISB’s expert without mentioning Appleseed’s objection.
    We therefore remand this issue for the Commissioner to specifically address
    Appleseed’s objection. See Appleseed 
    I, 54 A.3d at 1219
    (“[T]he technical nature
    of the actuarial reports requires a far more detailed discussion of a decision in which
    even a small variance can implicate millions of dollars.”).
    32
    H. Premium Growth Rate
    Another important consideration in projecting GHMSI’s financial future is
    estimating how many new subscribers GHMSI might have in the future and what
    premiums those subscribers might pay. The Commissioner projected a most likely
    premium growth rate of 8% with respect to GHMSI’s non-Federal Employee Plan
    subscribers. Appleseed argues that the Commissioner failed to adequately explain
    the reasoning behind this decision. We conclude otherwise. The Commissioner
    specifically discussed a number of considerations in explaining that decision,
    including the possible impact of the Affordable Care Act, rising health-care costs,
    the possibility that subscribers might choose plans with fewer benefits and lower
    premiums, and differences between Federal Employee Plan subscribers and non-
    Federal Employee subscribers.       We view the Commissioner’s explanation as
    sufficient.
    I. Real-World Data & Risks
    Appleseed argues that the Commissioner erred by not testing the reliability
    and plausibility of actuarial-model results against the historical record, evidence of
    actual real-world risks, and other facts outside the model. We disagree. The
    33
    actuarial models and the Commissioner’s analysis reflect reasonable efforts to make
    future predictions based in appropriate part on past information. Cf., e.g., Am. Pub.
    Gas Ass’n v. Fed. Power Comm’n, 
    567 F.2d 1016
    , 1037 (D.C. Cir. 1977) (“Reasoned
    decisionmaking can use an economic model to provide useful information about
    economic realities, provided there is a conscientious effort to take into account what
    is known as to past experience and what is reasonably predictable about the future.”).
    We agree with GHMSI, moreover, that “[h]olding surplus to guard against the
    potential that one or more costly events that have not previously occurred may occur
    in the future is how health insurance companies must be responsibly operated.”
    The Commissioner was reviewing in 2013 and 2014 what amount of surplus
    would have been appropriate for GHMSI to hold at the end of 2011, based on
    predictions about GHMSI’s financial situation in the period from 2012 to 2014. This
    meant that the actuarial models used to attempt to predict GHMSI’s future financial
    health had been outpaced at least in part by what actually happened. Ultimately, the
    Commissioner decided to rely on the actuarial models and approach the process as
    if calculations were being done at the end of 2011 with the information available at
    that time. To the extent that Appleseed contends that this decision was unreasonable,
    we conclude otherwise. Appleseed cites nothing in the MIEAA, or from any other
    authority, supporting the theory that the reasonableness of GHMSI’s 2011 surplus
    34
    must be assessed in hindsight, based on what actually happened in subsequent years.
    The Commissioner did not act unreasonably in instead assessing the reasonableness
    of the 2011 surplus based on what would reasonably have been predicted at that
    time. In many other contexts, it is well settled that reasonableness of an action
    should be determined based on the situation at the time of the action rather than
    based on hindsight. See, e.g., Kingsley v. Hendrickson, 
    135 S. Ct. 2466
    , 2473 (2015)
    (reasonableness of use of force should be assessed based on what “officer knew at
    the time, not with the 20/20 vision of hindsight”).
    J. Attribution of Excess Surplus to the District
    After determining that GHMSI’s overall surplus was excessive, the
    Commissioner turned to determining the extent to which the excess surplus was
    “attributable to the District.” D.C. Code § 31-3506(e). The MIEAA does not
    provide guidance about how to allocate excess surplus to the District. The pertinent
    regulation directs the Commissioner to
    allocate the portion of the surplus of a hospital and medical
    services corporation that is derived from the company’s
    operations in the District of Columbia based on the
    following factors:
    (a) The number of policies by geographic area;
    35
    (b) The number of health care providers under contract
    with the company by geographic area; and
    (c) Any other factor that the Commissioner deems to be
    relevant based on the record of a public hearing held
    pursuant to [26A DMCR] section 4602.
    26A DCMR § 4699.2 (2019).
    The Commissioner attributed 21% of GHMSI’s excess surplus to the District.
    In brief, the Commissioner’s reasoning was as follows: (1) the most relevant
    consideration is the geographic location of GHMSI’s health-insurance contracts, “as
    measured by the premiums reported and number of policies issued in each
    jurisdiction”; (2) the 2011 annual reports of GHMSI and one of its affiliates
    indicated that the District accounted for 18% of the premiums from Federal
    Employee Program (FEP) policies and 22% of the premiums for non-FEP policies;
    (3) because “FEP business is less risky,” greater weight should be given to non-FEP
    business than to FEP business, resulting in a weighted premium percentage for the
    District of 21%; (4) also using 2011 data, 19% of GHMSI’s policies were held by
    D.C. policyholders; (5) again using 2011 data, 15% of GHMSI’s network providers
    were located in the District; (6) policyholder data and provider location should be
    given less weight than premium data; and (7) weighting these three variables
    appropriately resulted in an allocation of 21% of the excess surplus to the District.
    36
    GHMSI has repeatedly challenged the reasonableness of allocating a portion
    of its surplus, which is unitary, to the District as one of the three jurisdictions in
    which GHMSI operates. The MIEAA, however, requires the Commissioner to
    undertake such an analysis. D.C. Code § 31-3506(e). We do not understand GHMSI
    to be arguing that this requirement of the MIEAA is invalid, and the Commissioner
    thus appropriately undertook to allocate a portion of the excess surplus to the
    District. GHMSI also at times appears to argue that, in allocating the excess surplus,
    the Commissioner was required to create a hypothetical smaller version of GHMSI
    that reflected only GHMSI’s activities in the District, and then to conduct the
    remainder of the analysis based on that hypothetical entity. We conclude that the
    Commissioner reasonably rejected that approach. GHMSI in fact is a bigger
    company, and (as GHMSI acknowledges) all of its surplus is available to protect
    against future financial problems. Moreover, D.C. Code § 31-3506(f) requires the
    Commissioner to consider all of GHMSI’s financial obligations in determining
    whether GHMSI’s surplus is excessive. It follows naturally that the full scope of
    GHMSI’s activities can appropriately be considered when the Commissioner
    determines whether GHMSI’s surplus is excessive and how much of any excess
    should be allocated to the District.
    37
    GHMSI and Appleseed raise numerous other objections to the
    Commissioner’s attribution methods and conclusions. We agree that a remand is
    necessary for the Commissioner to more fully address the issues raised by the parties.
    One conceivable approach to analyzing what portion of GHMSI’s excess
    surplus (if any) should be attributed to the District would be as follows: (1) decide
    what parts of GHMSI’s activity should be viewed as attributable to the District; (2)
    for any given year, determine the extent to which such D.C. activity added to or
    subtracted from the surplus, which in turn might turn on an assessment of (i) how
    much profit or loss resulted from the D.C. activity and (ii) to what extent the D.C.
    activity required greater or lesser surplus because of differential risk among the
    jurisdictions; and (3) because any excess surplus might be built up over years, make
    the same determination for other relevant years, rather than simply looking at
    information relating to a single year. Actually implementing such an approach
    would be extremely daunting from a practical point of view. There may a number
    of reasonable approaches to allocating excess surplus among jurisdictions. We
    would be inclined to give the Commissioner substantial latitude in determining how
    best to approach that issue.      We agree with the parties, however, that the
    Commissioner in this case has in a number of important respects not adequately
    explained the approach the Commissioner took to apportioning surplus.
    38
    Specifically, the Commissioner has in our view not provided adequate
    explanations in the following respects: (1) why the focus was on a snapshot of 2011
    rather than an effort to analyze GHMSI’s surplus history and to determine the
    District’s contributions to that surplus over time; (2) why the Commissioner
    addressed only to a very limited degree alleged differences among the District,
    Virginia, and Maryland with respect to the riskiness and profitability of GHMSI’s
    activities; and (3) why, in determining what activity should be attributed to the
    District, the Commissioner took as dispositive how GHMSI reported its activity,
    even though (a) GHMSI’s manner of reporting its activity has varied over time and
    (b) relying on GHMSI’s manner of reporting led the Commissioner to treat FEP
    policies differently from non-FEP policies without providing a sufficient rationale
    for such differential treatment. We therefore remand for further consideration of
    these issues. See generally, e.g., Appleseed 
    I, 54 A.3d at 1216
    (“Explanation in
    sufficient detail . . . is required for meaningful judicial review and for there to be a
    basis for judicial deference to agency determinations.”) (internal quotation marks
    omitted).
    39
    K. Actuarial Fees & Prejudgment Interest
    Citing a letter that it asserts can be found on DISB’s website, Appleseed states
    that it asked DISB to reimburse Appleseed’s actuarial fees. Without citation to the
    record, Appleseed also states that it asked DISB to award prejudgment interest.
    Appleseed further argues that the Commissioner did not address either request.
    DISB does not address either issue in its briefs in this court. GHMSI does not dispute
    that both requests were made to DISB and that the Commissioner did not address
    either request. Rather, GHMSI argues only that both requests should properly be
    denied on the merits. In general, however, “an administrative agency’s decision can
    be sustained on review only on the grounds on which the agency actually relied.”
    Black v. District of Columbia Dep’t of Human Servs., 
    188 A.3d 840
    , 850 (D.C.
    2018). “When a party asks us to affirm an agency’s decision for a reason not relied
    on by the agency, we thus ordinarily remand the case for the agency’s consideration
    in the first instance of the reason advanced by the party seeking affirmance.” 
    Id. at 851.
    We follow that course in the present case. On remand, the Commissioner
    should therefore address Appleseed’s requests for reimbursement of actuarial fees
    and for prejudgment interest, to the extent those requests remain at issue.

    L. Type of Community-Health Reinvestment
    The parties have extensively debated the Commissioner’s decision to order a
    rebate rather than some other type of community-health reinvestment. We are
    remanding the case for further proceedings, however, and therefore it is not at
    present clear whether the Commissioner will ultimately determine that it is
    appropriate to order community-health reinvestment and if so in what form. We
    therefore do not address at this time the disputes about the appropriate type of such
    reinvestment. See generally, e.g., Jackson v. Condor Mgmt. Grp., Inc., 
    587 A.2d 222
    , 224 (D.C. 1991) (declining to reach issues that “may or may not arise again on
    remand”).
    For the foregoing reasons, we affirm the Commissioner’s orders in part,
    vacate in part, remand for further proceedings.
    So ordered.
