    In 2010, Congress passed the Patient Protection and Affordable Care Act
    (“ACA”) to “increase the number of Americans covered by health insurance and
    decrease the cost of health care.” Nat’l Fed’n of Indep. Bus. v. Sebelius, 
    567 U.S. 519
    , 538 (2012); see ACA, Pub. L. No. 111-148, 124 Stat. 119 (2010) (codified
    primarily in title 42 of U.S.C.). Among its reforms, the ACA required private health
    insurers to provide coverage for individuals regardless of their gender or health
    status, including preexisting conditions. See 42 U.S.C. §§ 300gg-3, 300gg-4. It also
    2
    established “[h]ealth [b]enefit [e]xchanges” where individuals and small groups can
    purchase health insurance. 
    Id. § 18031(b)(1).
    1
    Congress anticipated these reforms might hamper the ability of insurers to
    predict health care costs and to price health insurance premiums as more individuals
    sought health insurance. See Standards Related to Reinsurance, Risk Corridors and
    Risk Adjustment, 77 Fed. Reg. 17,220, 17,221 (Mar. 23, 2012) (codified at 45 C.F.R.
    pt. 153) (“Stabilization Rule”). It also anticipated insurers might refuse to provide
    insurance plans on the exchanges if they could not reasonably estimate their potential
    costs. See 
    id. 2 To
    spread the risk of enrolling people who might need more health care than
    others, Congress established a risk adjustment program for the individual and small
    group health insurance markets. See 42 U.S.C. § 18063. 3 The program transfers

    Health benefit exchanges “make available qualified health plans to qualified
    individuals and qualified employers” in a state. 42 U.S.C. § 18031(d)(2)(A).

    Health insurance plans are “a defined set of benefits” offered by a health
    insurer to individuals seeking coverage of health care expenses. U.S. Dep’t of Health
    & Human Servs., Glossary of Terms (Nov. 18, 2019), https://perma.cc/GZ4D-DLHR.
    An insurer can offer multiple plans.

    The “‘individual market’ means the market for health insurance coverage
    offered to individuals other than in connection with a group health plan.” 42 U.S.C.
    § 18024(a)(2). The “small group market” means “the health insurance market under
    which individuals obtain health insurance coverage . . . through . . . a small
    employer.” 
    Id. § 18024(a)(3).
    3
    funds from plans with healthier enrollees to plans with sicker enrollees. A goal of
    the program is to discourage insurers from avoiding enrollment of sicker enrollees. 4
    Congress tasked the Department of Health and Human Services (“HHS”) with
    designing and implementing this risk adjustment program with the states. 
    Id. § 18063(b).
    HHS developed a formula to calculate how much each insurer would be charged or paid
    in each state. The formula relied on the “statewide average premium”—the average of all
    applicable premiums insureds pay to health insurers in a state—to calculate charges and
    payments.
    Plaintiff-Appellee New Mexico Health Connections (“NMHC”), an insurer that
    was required to pay charges under the program, sued the HHS Defendants-Appellants 5
    under the Administrative Procedure Act (“APA”). NMHC alleged that HHS’s use of the
    4
    In addition to the permanent risk adjustment program, the ACA established
    two other stabilization programs—risk corridors and reinsurance—which ran from
    2014 to 2016. See 42 U.S.C. §§ 18061, 18062. “These [three] programs [were]
    designed to provide consumers with affordable health insurance coverage, to reduce
    incentives for health insurance issuers to avoid enrolling sicker people, and to
    stabilize premiums. . . .” Ctrs. for Medicare & Medicaid Servs., Premium
    Stabilization Programs (Nov. 18, 2019), https://perma.cc/U7S9-8PRU. Only the risk
    adjustment program is at issue here.
    5
    NMHC sued HHS; Centers for Medicare and Medicaid Services (“CMS”);
    Alex M. Azar II, Secretary of HHS; and Seema Verma, Administrator of CMS. CMS
    is a part of HHS and administers the risk adjustment program. We refer to these
    Defendants-Appellants collectively as “HHS.”
    4
    statewide average premium to calculate charges and payments in New Mexico from 2014
    through 2018 was arbitrary and capricious. 6
    The district court granted summary judgment to NMHC, holding that HHS
    violated the APA by failing to explain why the agency chose to use the statewide average
    premium in its program. See N.M. Health Connections v. U.S. Dep’t of Health & Human
    Servs. (NMHC I), 
    312 F. Supp. 3d 1164
    , 1207-13 (D.N.M. 2018). The court faulted HHS
    for “erroneously read[ing] the ACA’s risk adjustment provisions to require” budget
    neutrality, which “infect[ed] [HHS’s] analysis of the relative merits of using a state’s
    average premium when calculating risk adjustment transfers instead of using a plan’s
    own premium.” 
    Id. at 1209.
    It remanded to the agency and vacated the 2014, 2015,
    2016, 2017, and 2018 rules that implemented the program. After the district court denied
    HHS’s motion to alter or amend judgment under Federal Rule of Civil Procedure 59(e),
    HHS appealed.
    Exercising jurisdiction under 28 U.S.C. § 1291:
    1. We hold NMHC’s claims regarding the 2017 and 2018
    rules are moot, so we remand to the district court to vacate
    its judgment on those claims and dismiss them as moot.
    2. We reverse the district court’s grant of summary judgment
    to NMHC as to the 2014, 2015, and 2016 rules. HHS
    6
    A health insurance premium is the “periodic payment (e.g. monthly,
    quarterly) . . . paid by a policyholder for insurance coverage.” U.S. Dep’t of Health
    & Human Servs., Glossary of Terms (Nov. 18, 2019), https://perma.cc/GZ4D-DLHR.
    We refer interchangeably to individuals who are covered by a health plan as
    “enrollees” and “insureds.”
    5
    acted reasonably in explaining why it used the statewide
    average premium in the formula.
    Because we reverse the district court on its summary judgment ruling in favor of
    NMHC, we need not address the denial of HHS’s Rule 59(e) motion.
    I. BACKGROUND
    This section describes the ACA’s risk adjustment program and summarizes the
    factual and procedural history of the case.
    A. The ACA’s Risk Adjustment Program
    Purpose
    Congress included the risk adjustment program in the ACA to stabilize health
    insurance premiums, encourage health insurers to provide plans on the exchanges,
    and discourage insurers from eluding enrollment of sicker individuals. See 2014
    Final Rule, 78 Fed. Reg. 15,410, 15,411 (Mar. 11, 2013), amended by 2014 Final
    Rule, 78 Fed. Reg. 65,046 (Oct. 20, 2013). The roles of “premiums” and “risk” in
    the health insurance market inform this purpose.
    Enrollees pay premiums to receive health insurance coverage. Insurers set their
    premiums “based on the anticipated revenue needs for their enrolled population.” Ctr. for
    Consumer Info. & Ins. Oversight, Risk Adjustment Implementation Issues, 13 (Sept. 12,
    2011) (“2011 White Paper”). Premiums differ from one plan to another for various
    reasons, including different estimated health care needs of each plan’s enrollees and the
    potential costs for those needs. See John Kautter et. al., Affordable Care Act Risk
    Adjustment: Overview, Context, and Challenges, 4 Medicare & Medicaid Res. Rev. 1, 5
    6
    (2014) (“Kautter Article”). Premiums also reflect a plan’s benefits and efficiency. See
    
    id. at 3.
    In setting insurance premiums, health insurers consider the risk of loss they
    might face from providing coverage to their enrollees. Risk is the probability that an
    insured event will occur, requiring the insurer to pay for it. 7 Among other sources of
    risk, the ACA reforms have exposed insurers to risk of financial loss due to adverse
    selection, which occurs when individuals who anticipate high health care needs are
    more likely to purchase coverage than those who anticipate low health care needs.
    See Stabilization Rule, 77 Fed. Reg. at 17,221. This can result in “a health plan
    having higher costs than anticipated.” 
    Id. Before the
    ACA, insurers could limit their risk by adjusting premiums based
    on the age, gender, and health status of their enrollees. See Katherine M. Kehres,
    Cong. Research Serv., R45334, The Patient Protection and Affordable Care Act’s
    Risk Adjustment Program: Frequently Asked Questions ii (Oct. 4, 2018) (“CRS
    Report”). They also “could deny coverage if an individual represented too much
    risk.” 
    Id. at 3.
    The ACA changed that. It forbids insurers from refusing to cover
    individuals with preexisting conditions and from “set[ting] premiums based on
    7
    “In health insurance parlance, ‘risk’ sometimes means simply ‘cost,’ with the
    implication that the realization of healthcare cost for an individual is uncertain.”
    Thomas G. McGuire & Richard C. van Kleef, Risk Sharing, in Risk Adjustment, Risk
    Sharing, and Premium Regulation in Health Insurance Markets 105 (Thomas G.
    McGuire & Richard C. van Kleef eds., 2018).
    7
    gender or health status.” 
    Id. at 1.
    An insurer “that enrolls a larger proportion of
    sicker (i.e., high-risk) enrollees than other plans in the market would [therefore] need
    to charge” a higher premium to be financially viable. 
    Id. at 7.
    The risk adjustment program aims to (1) reduce an insurer’s incentive to enroll
    only low-risk individuals, (2) encourage insurers to stay in the market, and (3) enable
    insurers to set premiums based on plan design and benefits rather than the health risk
    of enrollees in the plan. See 
    id. at ii,
    1, 7. It seeks to mitigate the impact of these
    reforms by subsidizing certain insurers for covering high-risk individuals without
    compensating them for other plan differences included in the price of their premiums.
    See Kautter Article at 3; Purva H. Rawal, The Affordable Care Act 161 (2016). HHS
    devised a formula that calculates “payment transfers . . . to help cover [plans’] actual
    risk exposure beyond the premiums the plans” can charge under the ACA. 2014
    Final Rule, 78 Fed. Reg. at 15,430.
    Statutory Basis
    Section 1343 of the ACA established the risk adjustment program. See 
    id. at 15,415.
    Codified at 42 U.S.C. § 18063, the statute provides:
    (a) In general
    (1) Low actuarial risk plans
    Using the criteria and methods developed under subsection
    (b), each State shall assess a charge on health plans and
    health insurance issuers (with respect to health insurance
    coverage) described in subsection (c) if the actuarial risk
    of the enrollees of such plans or coverage for a year is less
    8
    than the average actuarial risk of all enrollees in all plans
    or coverage in such State for such year that are not self-
    insured group health plans (which are subject to the
    provisions of the Employee Retirement Income Security
    Act of 1974).
    (2) High actuarial risk plans
    Using the criteria and methods developed under subsection
    (b), each State shall provide a payment to health plans and
    health insurance issuers (with respect to health insurance
    coverage) described in subsection (c) if the actuarial risk
    of the enrollees of such plans or coverage for a year is
    greater than the average actuarial risk of all enrollees in all
    plans and coverage in such State for such year that are not
    self-insured group health plans (which are subject to the
    provisions of the Employee Retirement Income Security
    Act of 1974).
    (b) Criteria and methods
    The Secretary, in consultation with States, shall establish
    criteria and methods to be used in carrying out the risk
    adjustment activities under this section. The Secretary
    may utilize criteria and methods similar to the criteria and
    methods utilized under part C or D of title XVIII of the
    Social Security Act. Such criteria and methods shall be
    included in the standards and requirements the Secretary
    prescribes under section 18041 of this title.
    (c) Scope
    A health plan or a health insurance issuer is described in
    this subsection if such health plan or health insurance
    issuer provides coverage in the individual or small group
    market within the State. This subsection shall not apply to
    a grandfathered health plan or the issuer of a grandfathered
    health plan with respect to that plan.
    9
    The ACA directed the Secretary of HHS, in consultation with the states, to
    “establish criteria and methods” to implement this program. 42 U.S.C. § 18063(b).
    A state can carry out its own approved program or HHS will do so on its behalf. See
    45 C.F.R. § 153.310(a). Only Massachusetts has managed its own program, but it
    ceased doing so in the 2017 benefit year. HHS has always managed New Mexico’s
    program and currently operates the program in all states.
    The statute does not authorize any legislatively appropriated funding for this
    program. Compare 42 U.S.C. § 18063 (not authorizing appropriations for ACA’s
    risk adjustment program) with 
    id. § 18042(g)
    (authorizing appropriations in ACA to
    provide loans to qualified health insurance issuers).
    Mechanics
    HHS implemented the risk adjustment program on behalf of states through
    rules promulgated in separate notice-and-comment proceedings for the 2014, 2015,
    2016, 2017, and 2018 benefit years. 8 Each succeeding rule employed the same
    methodology as the previous rules. See 2015 Final Rule, 79 Fed. Reg. 13,744,
    13,753 (Mar. 11, 2014) (“We proposed to use the [2014] methodology in 2015
    . . . .”); 2016 Final Rule, 80 Fed. Reg. 10,750, 10,760 (Feb. 27, 2015), corrected by
    2016 Final Rule, 80 Fed. Reg. 38,652 (July 7, 2015) (“We proposed to continue to
    8
    As used in the risk adjustment program, a “‘benefit year’ means a calendar
    year for which a health plan provides coverage for health benefits.” 45 C.F.R.
    § 155.20.
    10
    use the same risk adjustment methodology finalized in the 2014 [rule] . . . .”); 2017
    Final Rule, 81 Fed. Reg. 12,204, 12,217 (Mar. 8, 2016) (same); 2018 Final Rule, 81
    Fed. Reg. 94,058, 94,100 (Dec. 22, 2016) (“The payment transfer formula is
    unchanged from what was finalized in the 2014 [rule] . . . .”).
    To implement the program, HHS took the following steps for each benefit
    year:
    1. Published a proposed rule approximately one year before
    the applicable benefit year and, after a public comment
    period, published the final rule a few months later so
    insurers could rely on it to price their plans. See Supp.
    App. at 330; 45 C.F.R. § 153.100; 
    id. § 153.320(b).
    2. Collected enrollment and claims data from insurers. See
    45 C.F.R. § 153.70; see also CRS Report at 7.
    3. Calculated a “risk score,” which estimated the cost of each
    enrollee in each plan based on that person’s age, sex, and
    diagnoses. See, e.g., Ctr. for Consumer Info. & Ins.
    Oversight, HHS-Operated Risk Adjustment Methodology
    Meeting, 5-6 (Mar. 24, 2016) (“2016 White Paper”); 9 CRS
    Report at 7.
    4. Averaged the individual risk scores to calculate a “plan
    liability” risk score, which estimated an insurer’s costs for
    each of its plans. See 2016 White Paper at 5-6, 11; see
    also Kautter Article at 8; CRS Report at 7. HHS applied
    this step to each plan offered by an insurer. 10
    9
    The 2016 White Paper is not included in the appendices on appeal. We
    consider it, however, because it was included in the administrative record before the
    district court. See Dist. Ct. Doc. 25, Ex. A at 4.
    10
    The risk adjustment program calculates charges and payments on a plan-by-
    plan basis. See 42 U.S.C. § 18063. Because a health insurer could offer multiple
    plans, it could be paid for some plans and charged for others. See, e.g., Ctrs. for
    11
    5. Calculated how much plans would be charged or paid by
    applying to each plan a payment transfer formula, which
    included an estimated premium based on the “plan
    liability” risk score and other plan-specific cost factors
    (such as benefit design). See 2014 Final Rule, 78 Fed.
    Reg. at 15,417, 15,431; 2016 White Paper at 6, 11; see also
    Kautter Article at 8.
    6. Published the risk adjustment transfers, collected charges
    from insurers that covered healthier enrollees, and paid
    insurers who covered sicker enrollees. See 45 C.F.R.
    § 153.310; see also CRS Report at 8.
    Payment Transfer Formula and Statewide Average Premium
    The payment transfer formula referred to in step 5 is the focus of this case. 11 The
    basic concept is that a plan’s transfer is the difference between (1) its estimated premium
    Medicare & Medicaid Servs., Summary Report on Permanent Risk Adjustment
    Transfers for the 2018 Benefit Year, 13-33 (June 28, 2019), https://perma.cc/J9D9-
    9G7S.
    11
    As first published in the 2014 Final Rule (and later incorporated in the 2015,
    2016, 2017, and 2018 rules), the formula was:
    2014 Final Rule, 78 Fed. Reg. at 15,431.
    12
    given the health risk of its enrollees and (2) its estimated premium without the risk. See
    2014 Final Rule, 78 Fed. Reg. at 15,430; see also Gregory C. Pope et al., Risk Transfer
    Formula for Individual and Small Group Markets Under the Affordable Care Act, 4
    Medicare & Medicaid Res. Rev. 3 (2014) (“Pope Article”). “Both of these premium
    estimates are based on the [s]tate average premium.” 2014 Final Rule, 78 Fed. Reg. at
    15,430. The 2014 Final Rule distilled the formula as follows:
    See 
    id. at 15,431.
    If the transfer number is positive, a plan receives a payment. See 2016 White
    Paper at 11. If it is negative, a plan is charged. See 
    id. “Transfers are
    intended to
    bridge the gap between these two premium estimates.” 2014 Final Rule, 78 Fed.
    Reg. at 15,430. The transfers compensate health insurance plans for covering less
    healthy enrollees while preserving permissible premium differences. 2016 White
    Paper at 11.
    The risk adjustment rules made modest changes over the years. See 2016
    White Paper at 31-34. For the purposes of the APA challenge here, the program did
    not materially change from 2014 to 2018. We therefore rely on the description of the
    program stated in the 2014 Final Rule.
    13
    HHS performed these calculations for every plan offered by every insurer in
    the state and then used the results to determine which insurers would be charged and
    how much, and which insurers would be paid and how much. See 2014 Final Rule,
    78 Fed. Reg. at 15,431-32. The total amount charged minus the total paid by HHS
    “net[ted] to zero.” 
    Id. at 15,516.
    NMHC challenged only one aspect of this program: HHS’s use of the
    statewide average premium rather than each plan’s own premium in its payment
    transfer formula. See Aplee. Br. at 19. The former is an average of all the applicable
    health insurance premiums in a state. See 2014 Proposed Rule, 77 Fed. Reg. 73,118,
    73,126 (Dec. 7, 2012); 2014 Final Rule, 78 Fed. Reg. at 15,431-32. The latter would
    be the premiums that the plans set themselves. HHS uses the statewide average
    premium in the formula to convert the prior calculations into a dollar amount that
    equals the transfer charge or payment. See 2016 White Paper at 81.
    B. Agency and District Court Proceedings
    We present in chronological order the agency and district court proceedings
    leading to this appeal. As this presentation shows, the agency and court proceedings
    overlapped towards the end.
    We describe:
    1. HHS’s preparation for and its conduct of the notice-and-
    comment proceedings that led to the 2014 risk adjustment
    rule;
    14
    2. the agency’s notice-and-comment proceedings that led to
    the 2015, 2016, and 2017 rules;
    3. NMHC’s 2016 district court complaint;
    4. the agency’s proceedings that led to the 2018 rule;
    5. NMHC and HHS’s cross-motions for summary judgment
    and the district court’s ruling on those motions;
    6. HHS’s Rule 59(e) motion challenging the district court’s
    summary judgment order;
    7. the agency’s proceedings, in response to the district court’s
    summary judgment order, that led to modifications to the
    2017 and 2018 rules; and
    8. the district court’s denial of HHS’s Rule 59(e) motion.
    Notice-and-Comment Proceedings for the 2014 Rule
    HHS began its work on the risk adjustment program shortly after the ACA’s
    enactment. Before developing the details of the program, HHS promulgated a rule
    establishing general standards for the stabilization programs, including the risk
    adjustment program. 12 See Stabilization Rule, 77 Fed. Reg. at 17,220-52.
    12
    In the rulemaking process, HHS discussed the general features of the risk
    adjustment program, noting “risk adjustment is designed as a budget neutral
    activity.” Standards Related to Reinsurance, Risk Corridors and Risk Adjustment, 76
    Fed. Reg. 41,930, 41,938 (July 15, 2011) (“Proposed Stabilization Rule”). No
    commenter addressed the adequacy of HHS’s explanation of either budget neutrality
    or the statewide average premium in this rulemaking proceeding. See 
    id. at 41,937-40;
    Stabilization Rule, 77 Fed. Reg. at 17,220-52.
    15
    In late 2011, the Center for Consumer Information and Insurance Oversight
    (“CCIIO”), an agency within HHS charged with helping to implement ACA reforms,
    published a white paper on risk adjustment concepts to “begin the consultation
    process around the development of the [f]ederally-certified risk adjustment
    methodology developed by HHS and provide context for individuals to submit
    comments.” 2011 White Paper at 3; see 2014 Proposed Rule, 77 Fed. Reg. at 73,122.
    In a bulletin published in early 2012 (“2012 Bulletin”), HHS outlined its plan for
    implementing the program on behalf of a state. See 2014 Proposed Rule, 77 Fed.
    Reg. at 73,122. In mid-2012, HHS also hosted a public meeting to discuss the plan.
    See 
    id. On December
    7, 2012, HHS proposed the first risk adjustment rule for benefit
    year 2014. 2014 Proposed Rule, 77 Fed. Reg. at 73,118-218. It solicited and
    received comments for the rule and published the final rule on March 11, 2013 (“the
    2014 rule”). See 2014 Final Rule, 78 Fed. Reg. at 15,410-541.
    We describe the foregoing in greater depth below, focusing on HHS’s decision
    to use the statewide average premium in a risk adjustment program where total
    charges would equal total payments—that is, budget neutrality.
    a. 2011 White Paper
    In the 2011 White Paper, CCIIO considered four alternatives to establish a
    “baseline premium” for the payment transfer formula: “weighted state average
    premiums,” “weighted rating area average premiums,” “actuarial value-adjusted
    16
    weighted average premiums,” and “plans’ own premiums.” 2011 White Paper at
    14. 13 Because NMHC argued only in favor of using the plans’ own premiums, we
    focus on HHS’s choice to use the statewide average premium over the plans’ own
    premiums.
    CCIIO noted in the 2011 White Paper that using the statewide average
    premium “would result in balanced payments and charges” and “could be calculated
    with or without adjustment.” 
    Id. It expressed
    concern that using the plans’ own
    premiums would “create disincentives” for some plans because “the amount of
    charges and payments would be affected by each plan’s premiums.” 
    Id. It explained
    that “[f]or plans with a sicker than average risk mix, a lower premium plan would
    receive less in payments than a higher premium plan, even if the two plans have the
    same risk level.” 
    Id. CCIIO feared
    this “could create disincentives for high-risk
    plans to operate efficiently or set lower prices.” 
    Id. It also
    noted additional
    calculations would be needed for all options “except for the [s]tate average,” 
    id. at 15,
    meaning that using the statewide average premium would automatically make
    transfers net to zero whereas using plans’ own premiums would require additional
    adjustments.
    13
    The parties included only an excerpt of the 2011 White Paper in their
    appendices. We consider the entire 2011 White Paper because the agency relied on it
    in promulgating its 2014 rule and it was included in the administrative record below.
    See Dist. Ct. Doc. 25, Ex. A at 2.
    17
    CCIIO sought comments on each of the four alternatives and whether it should
    consider other alternatives. See 
    id. at 16-17.
    It also provided an appendix with
    “examples to examine implications of the approaches to calculate and balance
    payments and charges in greater detail.” 
    Id. at 16,
    29-56.
    b. 2012 Bulletin
    HHS described its key findings about operating the risk adjustment program in
    a 2012 bulletin—an informational guidance document. U.S. Dep’t of Health &
    Human Servs., Bulletin on the Risk Adjustment Program: Proposed Operations by
    the Department of Health and Human Services, 3-5 (May 1, 2012). It emphasized
    how permissible plan differences affect plan premiums. 
    Id. HHS said
    it would need
    to control these different factors to ensure “payment transfers compensate for liability
    differences due to health status” not for other permissible differences. 
    Id. at 5.
    HHS
    also noted its payment methodology “need[ed] to be balanced” and acknowledged
    this budget-neutral design “has significant implications for the equation that is used
    for calculating payments.” 
    Id. c. 2014
    Rule
    In its proposed 2014 rule, HHS explained its decision to use the statewide
    average premium in the formula in a section titled “Rationales for a Transfer
    Methodology Based on State Average Premiums.” See 2014 Proposed Rule, 77 Fed.
    Reg. at 73,139. It said the statewide average premium “provides a straightforward
    and predictable benchmark for estimating transfers.” 
    Id. Using the
    plans’ own
    18
    premiums “could introduce differences in premiums across plans that were not
    consistent with features of the plan.” 
    Id. HHS thus
    sought to balance predictability
    with “preserving premium differences.” 
    Id. No commenter
    challenged HHS’s decision to use the statewide average
    premium for the 2014 rule. See 2014 Final Rule, 78 Fed. Reg. at 15,430-32. Some
    comments supported HHS’s choice to do so. See 2014 Final Rule, 78 Fed. Reg. at
    15,432. For example, HHS noted, “We received a number of comments in support of
    our proposal to use the [s]tate average premium as the basis for risk adjustment
    transfers. One commenter suggested that use of a plan’s own premium may cause
    unintended distortions in the transfer formula.” 
    Id. In its
    responses to those
    comments, HHS said
    The goal of the payment transfer formula is, to the extent
    possible, to promote risk-neutral premiums. We agree
    with commenters that use of a plan’s own premium may
    cause unintended distortions in transfers. . . . We are
    finalizing our proposal to base the payment transfer
    formula on the [s]tate average premium.
    
    Id. No commenter
    challenged HHS’s decision to design its program as budget
    neutral such that transfer payments “net to zero.” See 2014 Proposed Rule, 77 Fed.
    Reg. at 73,139; 2014 Final Rule, 78 Fed. Reg. at 15,417-36.
    The risk adjustment program in the 2014 rule thus used the statewide average
    premium as the baseline in the formula. The rule provided that transfer payments and
    charges would be budget neutral, meaning HHS would not provide any additional
    19
    funds to pay for the transfers. The program developed in the 2014 rule became the
    blueprint HHS followed in promulgating the rules for the ensuing benefit years.
    Notice-and-Comment Proceedings for the 2015, 2016, and 2017 Rules
    HHS adopted a similar risk adjustment program in its 2015, 2016, and 2017
    rules. Because the rules used the statewide average premium in the payment transfer
    formula and built upon prior proceedings, the 2015, 2016, and 2017 rules relied on
    the same reasoning as the 2014 rule. See 2015 Final Rule, 79 Fed. Reg. at 13,753
    (“We proposed to use the [2014] methodology in 2015 . . . .”); 2016 Final Rule, 80
    Fed. Reg. at 10,760 (“We proposed to continue to use the same risk adjustment
    methodology finalized in the 2014 [rule] . . . .”); 2017 Final Rule, 81 Fed. Reg. at
    12,217 (same).
    a. 2015 Rule
    On December 2, 2013, HHS published a proposed rule for the 2015 benefit
    year. 2015 Proposed Rule, 78 Fed. Reg. 72,322, 72,322-92 (Dec. 2, 2013). On
    March 11, 2014, it published the final rule for 2015 (“the 2015 rule”). 2015 Final
    Rule, 79 Fed. Reg. at 13,744-843. HHS included no additional reasoning about its
    decision to use the statewide average premium or its budget-neutral design, see 2015
    Proposed Rule, 78 Fed. Reg. at 72,322-92; 2015 Final Rule, 79 Fed. Reg. at 13,744-
    843, and no commenter challenged either, see 2015 Final Rule, 79 Fed. Reg. at
    13,744-843.
    20
    b. 2016 Rule
    On November 26, 2014, HHS published a proposed rule for the 2016 benefit
    year. 2016 Proposed Rule, 79 Fed. Reg. 70,674, 70,674-760 (Nov. 26, 2014). On
    February 27, 2015, it published the final rule for 2016 (“the 2016 rule”). 2016 Final
    Rule, 80 Fed. Reg. at 10,750-877. As with the 2015 rule, HHS included no
    additional reasoning about its decision to use the statewide average premium or its
    budget-neutral design, see 2016 Proposed Rule, 79 Fed. Reg. at 70,674-760; 2016
    Final Rule, 80 Fed. Reg. at 10,750-877, and no commenter challenged either, see
    2016 Final Rule, 80 Fed. Reg. at 10,750-877.
    c. 2017 Rule
    On December 2, 2015, HHS published a proposed rule for the 2017 benefit
    year. 2017 Proposed Rule, 80 Fed. Reg. 75,488, 75,488-588 (Dec. 2, 2015). HHS
    published the final rule for 2017 on March 8, 2016 (“the 2017 rule”). 2017 Final
    Rule, 81 Fed. Reg. at 12,204-352. For the first time, HHS received comments
    opposing its use of the statewide average premium. It reported
    Some commenters opposed the use of the statewide
    average premium because it disadvantages issuers with
    below average premiums. Commenters requested that
    2014 and later risk adjustment transfers for all plans with
    below average premiums in a [s]tate be calculated using
    the plans’ own average premium amount or average claims
    cost, so that efficient plans are not penalized using the
    [s]tatewide average premium.
    
    Id. at 12,230.
    HHS responded
    21
    We did not propose changes to the transfer formula, and
    therefore, are not addressing comments that are outside the
    scope of this rulemaking. We may be able to evaluate
    geographic differences in the future if we obtain enrollee-
    level data for future recalibrations—a topic that we also
    intend to discuss in the White Paper and at the March 31,
    2016 risk adjustment conference.
    
    Id. On March
    24, 2016, HHS circulated the aforementioned white paper, which
    assessed the formula. See 2016 White Paper at 79-101. In it, CCIIO noted it used the
    statewide average premium both as “a premium and a cost scaling factor.” 
    Id. at 83.
    It explained
    Over the long run, the [s]tatewide average premium is
    expected to equal the [s]tatewide average cost (including
    allowable loading for administrative costs, surplus, and
    profit). The [s]tatewide premium is therefore
    simultaneously a premium and cost scaling factor. The
    [s]tatewide average premium embeds an average level of
    efficiency. All plans receive a risk adjustment payment or
    charge sufficient for a plan with average efficiency.
    Two other reasons that transfers are scaled by the
    [s]tatewide average premium, as opposed to, for example,
    the plan’s own premium, are:
    • Using the [s]tatewide average premium minimizes
    issuers’ ability to manipulate their transfers by
    adjusting their own plan premiums.
    • Scaling all transfers to the same premium, combined
    with the assumption that the factors affecting
    premium requirements and allowable revenue have a
    multiplicative relationship, obviates any further
    adjustment of payments and charges to ensure that
    22
    risk adjustment transfers for the entire market sum
    to zero.
    
    Id. NMHC’s District
    Court Complaint
    On July 29, 2016, NMHC sued HHS, alleging that the agency violated § 1343
    of the ACA and § 706 of the APA. Dist. Ct. Doc. 1 at 43-45. 14 NMHC alleged
    HHS’s use of the statewide average premium in its risk adjustment program in 2014,
    2015, 2016, and 2017 was “arbitrary, capricious, and unlawful.” 
    Id. at 45.
    It
    asserted that HHS “flout[ed] Congressional intent and the express mandate of the
    Risk Adjustment statute.” 
    Id. NMHC filed
    its amended complaint on January 12,
    2017, adding a challenge to the 2018 rule. See Supp. App. at 68-69.
    Notice-and-Comment Proceedings for the 2018 Rule
    On September 6, 2016, HHS published a proposed rule for the 2018 benefit
    year. 2018 Proposed Rule, 81 Fed. Reg. 61,456, 61,456-536 (Sept. 6, 2016).
    Because the 2018 rule incorporated and built upon previous proceedings, it relied on
    the same reasoning as the prior rules. See 2018 Final Rule, 81 Fed. Reg. at 94,100
    14
    Other lawsuits challenging the risk adjustment program include Minuteman
    Health Inc. v. U.S. Dep’t of Health & Human Servs., 
    291 F. Supp. 3d 174
    , 202 (D.
    Mass. 2018) (holding HHS’s use of the statewide average premium was not arbitrary
    and capricious), appeal not filed; Evergreen Health Coop., Inc. v. U.S. Dep’t of
    Health & Human Servs., No. 16-2039 (D. Md. Jan. 31, 2017) (entering stipulated
    dismissal of challenge to risk adjustment program); and Ommen v. United States, No.
    17-957 (Fed. Cl. July 25, 2019) (staying risk adjustment challenge pending the
    Supreme Court’s resolution of Moda Health Plan, Inc. v. United States, No. 18-1028
    (Oct. 25, 2019)).

    (“The payment transfer formula is unchanged from what was finalized in the 2014
    [rule] . . . except with an adjustment to remove a portion of the administrative costs
    from the [s]tatewide average premium . . . .”).
    On December 22, 2016, HHS published the final rule for 2018 (“the 2018
    rule”). 
    Id. at 94,058-183.
    HHS noted “[a] few commenters requested that HHS use a
    plan’s own actual average premium instead of the [s]tatewide average premium in the
    transfer formula.” 
    Id. at 94,100.
    HHS responded
    We have considered the use of a plan’s own premium
    instead of the [s]tatewide average premium. However, our
    analysis determined that this approach is likely to lead to
    substantial volatility in transfer results and even higher
    transfer charges for low-risk low-premium plans. Under
    such an approach, high-risk, high-premium plans would
    require even greater transfer payments; thus, low-risk, low-
    premium plans would be required to pay in an even higher
    percentage of their plan-specific premiums in risk
    adjustment transfer charges. In other words, the use of a
    plan’s own premium does not reduce risk adjustment
    charges for low-cost and low-risk issuers, given the budget
    neutrality of the risk adjustment program.
    
    Id. For the
    first time, HHS received comments challenging the budget-neutral
    design of the program. HHS reported
    A few commenters noted that the budget neutrality of the
    risk adjustment program leads to inadequate compensation
    for enrollees’ risk and recommended a non-budget neutral
    risk adjustment program as with Medicare Advantage.
    
    Id. at 94,101.
    It responded
    24
    In the absence of additional funding for the HHS-operated
    risk adjustment program, we continue to calculate risk
    adjustment transfers in a budget neutral manner and note
    that Medicare Part D risk adjustment transfers are also
    calculated in a budget neutral manner.
    
    Id. Cross-Motions for
    Summary Judgment and District Court Order
    In mid-2017, both NMHC and HHS moved for summary judgment. In its
    motion, NMHC made several arguments, including that HHS’s use of the statewide
    average premium to calculate risk adjustment transfer payments was arbitrary and
    capricious. It asserted it was charged $6,666,798 in transfer charges for the 2014
    benefit year, representing 21.5 percent of its premiums. NMHC further asserted it
    was charged $14,569,495.74 for the 2015 benefit year, representing 14.7 percent of
    its premiums. NMHC alleged these fees were debilitating because industry margins
    were “typically, at best, a razor thin 2% [to] 3%.” Supp. App. at 258.
    In its cross motion for summary judgment, HHS contended its methodology
    was “eminently reasonable” and “easily satisfie[d] the APA’s standard of review.”
    
    Id. at 335.
    The district court granted summary judgment for NMHC, finding that HHS’s
    use of the statewide average premium was arbitrary and capricious. NMHC I, 312 F.
    Supp. 3d at 1170-72. 15 It noted that, “even though both [NMHC] and HHS ostensibly
    15
    NMHC and HHS advanced multiple arguments. The district court rejected
    all of NMHC’s claims except the one we address on appeal. The court concluded:
    25
    filed motions for summary judgment,” “district courts reviewing agency action do not
    determine whether a genuine dispute as to any material fact exists, and instead
    engage in a substantive review of the record to determine if the agency considered
    relevant factors or articulated a reasoned basis for its conclusions.” 
    Id. at 1171
    (quotations and citations omitted).
    In reviewing the APA challenge, the district court stated the issue was
    “whether incorporating statewide average premiums in . . . [the] risk[]adjustment
    [program] is contrary to law or arbitrary and capricious.” 
    Id. at 1170.
    It held that
    “HHS’[s] use of statewide average premiums in its risk adjustment [program] is not
    contrary to law, but is arbitrary and capricious.” 
    Id. The court
    said, “HHS assumed,
    erroneously, that the ACA requires risk adjustment to be budget neutral, and all of
    HHS’[s] reasons for using the statewide average premium rely on that budget
    neutrality assumption.” 
    Id. at 1202.
    It noted HHS had justified using the statewide
    average premium to achieve “budget neutrality and predictability.” 
    Id. at 1209.
    The
    court said that this assumption “infect[ed]” HHS’s “analysis of the relative merits of
    (1) the APA waived sovereign immunity for all claims presented; (2) HHS’s
    approach to predicting costs for enrollees (hierarchal condition category (“HCC”)
    “and non-HCC eligible enrollees”) was not arbitrary and capricious; (3) HHS’s
    decisions regarding partial-year enrollees and the use of prescription drug data in its
    risk adjustment model were not arbitrary and capricious; and (4) HHS’s payment
    transfer formula did not ban bronze health insurance plans. NMHC I, 
    312 F. Supp. 3d
    at 1171. We do not address these rulings because NMHC did not appeal the
    judgment.
    26
    using a state’s average premium . . . instead of a plan’s own premium,” including
    HHS’s explanation that the statewide average premium was more predictable. 
    Id. The district
    court vacated HHS’s 2014, 2015, 2016, 2017, and 2018 rules. 
    Id. at 1170-71.
    It entered judgment and remanded the case to the agency for further
    proceedings. 
    Id. HHS’s Rule
    59(e) Motion
    HHS moved to alter or amend the judgment under Federal Rule of Civil
    Procedure 59(e). First, it argued NMHC had waived any argument that HHS acted
    arbitrarily and capriciously regarding the budget-neutral design of the program
    because no commenter had challenged budget neutrality in the 2014, 2015, 2016, or
    2017 rulemaking proceedings. HHS also said it sufficiently explained its budget-
    neutral design when it received comments to the 2018 rule. Second, HHS contended
    it had not interpreted the ACA to mandate budget neutrality but rather had designed
    the payment transfer formula to be budget neutral because no appropriations from
    Congress were available for the program. Third, HHS argued that vacating the rules
    was not required under the APA and would be manifestly unjust.
    Notice-and-Comment Proceedings for the Modified 2017 and 2018 Rules
    While this Rule 59(e) motion was pending, HHS attempted to adjust its 2017
    and 2018 rules in response to the district court’s summary judgment order. On July
    7, 2018, HHS suspended risk adjustment transfers for 2017 based on the uncertainty
    created by this case. See N.M. Health Connections v. U.S. Dep’t of Health & Human
    27
    Servs. (NMHC II), 
    340 F. Supp. 3d 1112
    , 1141 (D.N.M. 2018). HHS then notified
    the district court that it was formulating a new interim final rule for 2017. See Dist.
    Ct. Doc. 78 at 1-2.
    On July 25, 2018, HHS sent a letter to the district court announcing it had
    issued a new final rule on the risk adjustment methodology for the 2017 benefit year
    (“the new 2017 rule”). Dist. Ct. Doc. 81 at 1. Although the new rule adopted the
    same methodology as prior rules, HHS “provide[d] additional explanation of the
    agency’s use of [the] statewide average premium in the risk adjustment payment
    transfer formula, as well as the risk adjustment program’s budget neutral design.” 
    Id. at 1.
    In the new 2017 rule, HHS explained it chose to use the statewide average
    premium to “support[] the overall goal of the risk adjustment program to encourage
    issuers to” set premium rates “for the average risk in the applicable state market risk
    pool.” New 2017 Final Rule, 83 Fed. Reg. 36,456, 36,457 (July 30, 2018). HHS also
    noted that using the statewide average premium “avoids the creation of incentives for
    issuers to operate less efficiently, set higher prices, develop benefit designs or create
    marketing strategies to avoid high risk enrollees.” 
    Id. HHS also
    explained that it chose to use a budget-neutral design for the
    program for several reasons. First, “Congress designed the risk adjustment program
    to be implemented and operated by states if they choose to do so,” and HHS could
    not require the states to provide funding. 
    Id. at 36,458.
    Second, it noted the ACA
    28
    “neither authorized nor appropriated additional funding for risk adjustment payments
    beyond the amount of charges paid in.” 
    Id. “Thus, as
    a practical matter, Congress
    did not give HHS discretion to implement a program that was not budget neutral.”
    
    Id. Third, “if
    HHS had elected to adopt a . . . methodology that was contingent on
    appropriations from Congress . . . that would have created uncertainty for issuers in
    the amount of risk adjustment payments they could expect.” 
    Id. After issuing
    the
    new rule, HHS implemented transfer payments for the 2017 benefit year. 
    Id. at 36,459.
    On August 8, 2018, HHS sent a letter to the district court announcing it had
    issued a new proposed rule for the 2018 benefit year. Dist. Ct. Doc. 84 at 1; see New
    2018 Proposed Rule, 83 Fed. Reg. 39,644, 39,644-48 (Aug. 10, 2018). HHS noted
    the new rule would respond to the district court’s summary judgment decision by
    providing additional explanation of the agency’s use of the statewide average
    premium and the program’s budget-neutral design. Dist. Ct. Doc. 84 at 1-2. HHS
    said it had sought comments on the issues. 
    Id. at 1.
    It also argued its proceedings on
    the 2017 and 2018 rules did not moot its Rule 59(e) motion regarding the 2014, 2015,
    and 2016 rules. 
    Id. at 2.
    16
    16
    The new 2018 final rule was promulgated on December 10, 2018, after the
    district court’s denial of the 59(e) motion (“the new 2018 rule”). New 2018 Final
    Rule, 83 Fed. Reg. 63,419, 63,419-28 (Dec. 10, 2018). HHS had received comments
    related to its use of the statewide average premium and the program’s budget-neutral
    design. 
    Id. at 63,422-27.
    Its responses to those comments contained explanations
    similar to those outlined in its new 2017 rule. See 
    id. 29 On
    August 13, 2018, NMHC filed a letter with the court, arguing HHS’s
    motion on Rule 59(e) “is now entirely moot as to 2017 and 2018.” Dist. Ct. Doc.
    85 at 1.
    Denial of Rule 59(e) Motion
    The district court denied HHS’s Rule 59(e) motion. NMHC II, 
    340 F. Supp. 3d
    at 1121. First, it found HHS had sua sponte considered using the statewide
    average premium over alternatives, so the absence of comments challenging budget
    neutrality did not forfeit the issue. 
    Id. at 1168.
    Second, it reiterated that the payment
    transfer formula was arbitrary and capricious because HHS had insufficiently
    explained the budget-neutral design of its program. 
    Id. at 1165-66.
    The court
    claimed HHS could have relied on Congress’s “lump sum” appropriations to
    subsidize a non-budget-neutral formula program. 
    Id. at 1174.
    Third, the court
    maintained vacatur was the proper remedy under the APA. 
    Id. at 1175-84.
    After the
    denial of HHS’s Rule 59(e) motion, the agency timely appealed.
    II. JURISDICTION
    We address two jurisdictional issues. We conclude (A) we have appellate
    jurisdiction because the administrative remand rule does not apply, and (B) NMHC’s
    challenges to the 2017 and 2018 rules are moot.
    A. Appellate Jurisdiction
    We must determine whether the administrative remand rule precludes our
    appellate jurisdiction. Under that rule, “[a] remand by a district court to an
    30
    administrative agency for further proceedings is ordinarily not appealable because it
    is not a final decision.” W. Energy All. v. Salazar, 
    709 F.3d 1040
    , 1047 (10th Cir.
    2013) (quotations omitted). Here, the district court’s summary judgment order
    determined HHS had violated the APA because its implementation of the risk
    adjustment program was arbitrary and capricious. It remanded that issue to HHS.
    This court ordered the parties to address whether we lack jurisdiction under the
    administrative remand rule in their briefs. Although neither party contests our
    appellate jurisdiction, “federal courts are under an independent obligation to examine
    their own jurisdiction.” United States v. Hays, 
    515 U.S. 737
    , 742 (1995).
    “[W]e exercise jurisdiction over final decisions of the federal district courts
    pursuant to 28 U.S.C. § 1291.” Am. Wild Horse Pres. Campaign v. Jewell, 
    847 F.3d 1174
    , 1183 (10th Cir. 2016) (quotations omitted). “A final decision is one ‘that ends
    the litigation on the merits and leaves nothing for the court to do but execute the
    judgment.’” W. Energy 
    All., 709 F.3d at 1047
    (quotations omitted). In determining
    whether the district court’s order was a final decision under the administrative
    remand rule, “this court considers the nature of the agency action as well as the
    nature of the district court’s order.” Cherokee Nation v. Bernhardt, 
    936 F.3d 1142
    ,
    1151 (10th Cir. 2019) (quotations omitted).
    As to the nature of the agency action, we consider whether it was “essentially
    adjudicatory, essentially legislative, or some nonadversarial action such as grant of a
    license.” Am. Wild Horse Pres. 
    Campaign, 847 F.3d at 1184
    (quotations omitted).
    31
    Adjudicatory action affects individuals in their individual capacity. W. Energy 
    All., 709 F.3d at 1048
    . Legislative action “affects the rights of individuals in the abstract
    and must be applied in a further proceeding before the legal position of any particular
    individual will be definitively” affected. 
    Id. (quotations omitted).
    “[O]ur precedent
    indicates that we view the remand rule as most appropriate in adjudicative contexts.”
    Am. Wild Horse Pres. 
    Campaign, 847 F.3d at 1184
    (quotations omitted).
    As to the district court’s order, we consider its character, “including whether it
    returns an action to . . . the agency for further proceedings.” 
    Id. (alterations and
    citations omitted). If the district court’s order is not a “remand in the typical sense,”
    the administrative remand rule is inapplicable. W. Energy 
    All., 709 F.3d at 1047
    (quotations omitted).
    We conclude the district court’s summary judgment order was a final,
    appealable decision and the administrative remand rule does not apply. First, HHS
    acted in a legislative capacity in promulgating the rules. See N.M. ex rel. Richardson
    v. Bureau of Land Mgmt., 
    565 F.3d 683
    , 698 (10th Cir. 2009) (holding agency action
    was final decision where agency proceeding was “quasi-legislative”). Second,
    although the district court’s order remanded to HHS to correct deficiencies, the 2014,
    2015, and 2016 transfer payments have already occurred, so the order “does not share
    the features of a typical remand.” Am. Wild Horse Pres. 
    Campaign, 847 F.3d at 1184
    (holding agency action was final decision where action based on the challenged rule
    had already taken place and remand was to “correct procedural deficiencies” in rule
    32
    analysis). And, as discussed below, NMHC’s challenges to the 2017 and 2018 rules
    are moot.
    The district court’s disposition was not an administrative remand but a final
    order. We have jurisdiction under 28 U.S.C. § 1291. 17
    B. NMHC’s Challenges to the 2017 and 2018 Rules Are Moot
    NMHC asserts its “challenges to the old 2017 and 2018 [rules] are moot.” Aplee.
    Br. at 45. 18 We agree. “We have no subject-matter jurisdiction if a case is moot.” Rio
    17
    Even if the district court’s disposition was an administrative remand, the
    order was final and appealable under the “practical finality exception” to the
    administrative remand rule. “[W]e employ a two-pronged test for applying the
    practical finality rule: the issue must be important and it must be urgent.” W. Energy
    
    All., 709 F.3d at 1049-50
    (quotations omitted). “If the test is met, we then follow a
    balancing approach . . . .” 
    Id. at 1050
    (quotations omitted). “In practice, we have
    applied the practical finality rule when it is necessary to ensure that we can review
    important legal questions which a remand may make effectively unreviewable,
    because administrative agencies may be barred from seeking district court (and thus
    circuit court) review of their own administrative decisions.” Miami Tribe of Okla. v.
    United States, 
    656 F.3d 1129
    , 1140 (10th Cir. 2011) (quotations omitted). Here, the
    issue is important, and it is urgent to review this case on appeal because any
    additional delay could have a significant effect on the national health insurance
    market. The importance and urgency factors outweigh the inconvenience and cost of
    piecemeal review. Moreover, HHS might be foreclosed from future appellate review
    because it could not challenge changes to its own program based on the district
    court’s holding. See 
    id. 18 In
    a Rule 28(j) letter, NMHC adds it “will not be challenging the new 2018 rule
    as it has suffered no injury.” Aplee. 28(j) Letter, Doc. 10662343 at 2. At oral argument,
    HHS argued NMHC’s challenges to the 2017 and 2018 rules are not moot but provided
    no explanation. Or. Arg. at 3:08-3:22. Nor did it argue mootness in its briefing. Aplt.
    Reply Br. at 17. Although NMHC raised mootness below after the new 2017 and 2018
    rules were promulgated, the district court did not address mootness in its order denying
    HHS’s Rule 59(e) motion. See NMHC II, 
    340 F. Supp. 3d
    at 1120-84.
    33
    Grande Silvery Minnow v. Bureau of Reclamation, 
    601 F.3d 1096
    , 1109 (10th Cir. 2010).
    We review questions of mootness de novo as “squarely a legal determination.” Brown v.
    Buhman, 
    822 F.3d 1151
    , 1168 (10th Cir. 2016) (quotations omitted).
    Mootness
    Article III of the Constitution permits federal courts to decide only “Cases” or
    “Controversies.” U.S. Const. art. III, § 2; see Hollingsworth v. Perry, 
    570 U.S. 693
    , 704
    (2013). “This case-or-controversy requirement subsists through all stages of federal
    judicial proceedings, trial and appellate.” Spencer v. Kemna, 
    523 U.S. 1
    , 7 (1998)
    (quotations omitted). At the appellate stage, it “requires a party seeking relief to have
    suffered, or be threatened with, an actual injury traceable to the appellee and likely to be
    redressed by a favorable judicial decision by the appeals court.” United States v.
    Vera-Flores, 
    496 F.3d 1177
    , 1180 (10th Cir. 2007) (alterations and quotations omitted).
    “A case becomes moot—and therefore no longer a ‘Case’ or ‘Controversy’ for
    purposes of Article III—when the issues presented are no longer live or the parties lack a
    legally cognizable interest in the outcome.” Already, LLC v. Nike, Inc., 
    568 U.S. 85
    , 91
    (2013) (quotations omitted). “If an intervening circumstance deprives the plaintiff of a
    personal stake in the outcome of the lawsuit, at any point during litigation, the action can
    no longer proceed and must be dismissed as moot.” 
    Brown, 822 F.3d at 1165
    (quoting
    Campbell-Ewald Co. v. Gomez, 
    136 S. Ct. 663
    , 669 (2016)). “Corrective action by an
    agency is one type of subsequent development that can moot a previously justiciable
    issue.” Nat. Res. Def. Council, Inc. v. U.S. Nuclear Reg. Comm’n, 
    680 F.2d 810
    , 814
    34
    (D.C. Cir. 1982). An agency’s action moots an appeal “[b]y eliminating the issues upon
    which this case is based.” Hayes v. Osage Mins. Council, 699 F. App’x 799, 803 (10th
    Cir. 2017) (quoting Wyoming v. U.S. Dep’t of Agric., 
    414 F.3d 1207
    , 1212 (10th Cir.
    2005)). 19
    Courts recognize two exceptions to mootness. First, a case or controversy is
    not moot if the dispute is “capable of repetition, yet evading review.” 
    Brown, 822 F.3d at 1166
    (quotations omitted). This exception “applies where (1) the challenged
    action is in its duration too short to be fully litigated prior to cessation or expiration,
    and (2) there is a reasonable expectation that the same complaining party will be
    subject to the same action again.” 
    Id. (quoting Fed.
    Election Comm’n v. Wis. Right
    to Life, Inc., 
    551 U.S. 449
    , 462 (2007)).
    Second, “voluntary cessation of challenged conduct does not ordinarily render
    a case moot because a dismissal for mootness would permit a resumption of the
    challenged conduct as soon as the case is dismissed.” 
    Id. (quoting Knox
    v. Serv.
    Emps. Int’l Union, Local 1000, 
    567 U.S. 298
    , 307 (2012)). This exception is
    designed to counteract gamesmanship, such as “a defendant ceasing illegal action
    long enough to render a lawsuit moot” before “resuming the illegal conduct.” Ind v.
    19
    Although not precedential, we find the reasoning of the unpublished
    decisions cited in this opinion instructive. See 10th Cir. R. 32.1 (“Unpublished
    decisions are not precedential, but may be cited for their persuasive value.”); Fed. R.
    App. P. 32.1 (same).
    35
    Colo. Dep’t of Corrs., 
    801 F.3d 1209
    , 1214 (10th Cir. 2015) (quotations omitted). It
    does not apply, however, if it is “absolutely clear the allegedly wrongful behavior
    could not reasonably be expected to recur.” 
    Brown, 822 F.3d at 1166
    (quotations
    omitted). Government “self-correction . . . provides a secure foundation for
    mootness so long as it seems genuine.” 13C Charles Alan Wright, Arthur R. Miller,
    & Edward H. Cooper, Fed. Prac. & Proc. Juris. § 3533.7 (3rd ed. 2008); see also Rio
    Grande Silvery 
    Minnow, 601 F.3d at 1117-18
    (holding “withdrawal or alteration of
    administrative policies” satisfies concerns regarding voluntary cessation (quotations
    omitted)).
    Analysis
    Although HHS appealed the district court’s summary judgment order as to the
    2014, 2015, 2016, 2017, and 2018 risk adjustment rules, NMHC’s challenges to the
    2017 and 2018 rules became moot when HHS modified them. NMHC has not
    challenged the modified rules.
    While its Rule 59(e) motion was pending, HHS (1) issued an emergency new risk
    adjustment final rule for the 2017 benefit year and (2) conducted rulemaking proceedings
    for a new risk adjustment rule for the 2018 benefit year. See New 2017 Final Rule, 83
    Fed. Reg. at 36,456; New 2018 Proposed Rule, 83 Fed. Reg. at 39,644; New 2018 Final
    Rule, 84 Fed. Reg. at 63,419. Both proceedings modified and superseded the original
    2017 and 2018 rules. See 
    id. In its
    new 2017 and 2018 rules, HHS included explanations
    about why it used the statewide average premium in its transfer formula and why it
    36
    designed its program to be budget neutral. See New 2017 Final Rule, 83 Fed. Reg. at
    36,457-58; New 2018 Final Rule, 83 Fed. Reg. at 63,420-27.
    These actions cured the defects identified in the district court’s order for the
    original 2017 and 2018 rules. Because the new 2017 and 2018 rules supersede the
    old ones, 20 any decision by this court regarding the original 2017 and 2018 rules
    “would be wholly without effect in the real world.” Rio Grande Silvery 
    Minnow, 601 F.3d at 1112
    ; see also 
    Wyoming, 414 F.3d at 1212
    (noting “the alleged procedural
    deficiencies of the . . . [r]ule are now irrelevant because the replacement rule was
    promulgated in a new and separate rulemaking process”). NMHC’s challenges to the
    original 2017 and 2018 rules are therefore moot. 21
    20
    See New 2017 Final Rule, 83 Fed. Reg. at 36,457 (“This final rule adopts the
    HHS-operated risk adjustment methodology previously published [in the original
    2017 Final Rule] for the 2017 benefit year with an additional explanation regarding
    the use of the statewide average premium and the budget-neutral nature of the
    program.”); New 2018 Final Rule, 83 Fed. Reg. at 63,419 (same as to 2018 benefit
    year).
    21
    NMHC has not challenged these curative actions or the new rules, and, as
    noted above, considers its case regarding the original 2017 and 2018 rules moot.
    NMHC filed a separate challenge to the new 2017 rule. See Aplee. Br. at 46;
    Complaint, N.M. Health Connections v. U.S. Dep’t of Health & Human Servs., No.
    18-773 (D.N.M. Aug. 13, 2018), ECF No. 1. That case has been stayed by agreement
    of the parties pending this appeal. See Aplee. Br. at 46; Joint Status Report, N.M.
    Health Connections v. U.S. Dep’t of Health & Human Servs., No. 18-773 (D.N.M.
    Jan. 28, 2019), ECF No. 31. In its brief on appeal, NMHC noted it “has not yet
    decided whether it will seek to amend its complaint in the second action to challenge
    the new 2018 rule,” but it “did submit a 35-page comment, attaching 86 exhibits, in
    response to the proposed new 2018 rule.” Aplee. Br. at 46 n.11.
    37
    Neither exception to the mootness doctrine applies here. Mooting this case
    would not run afoul of the “capable of repetition” exception because any future
    failure to explain the agency rulemaking would allow NMHC ample time and
    opportunity to challenge HHS’s action. HHS is also unlikely to subject NMHC to a
    purportedly unexplained decision to use the statewide average premium or budget
    neutrality in future rules given the agency’s extensive explanation on those matters in
    the new 2017 and 2018 rules and the agency’s practice on each successive risk
    adjustment rule to build on and incorporate prior ones. The additional explanations
    provided in the new 2017 and 2018 rules will likely be incorporated into future rules
    relying on the same formula.
    Nor does the “voluntary cessation” exception apply. Mooting NMHC’s
    challenges to the 2017 and 2018 rules would not offer HHS an opportunity to resume
    “the challenged conduct.” 
    Brown, 822 F.3d at 1166
    . HHS already has replaced the
    original rules with these new ones and has added explanation to satisfy the district
    court. It cannot revert to the original rules without a new proceeding, see 5 U.S.C.
    § 553, which is unlikely as the new rules replace the original ones and the agency
    followed them to implement the program for 2017 and 2018. See Rio Grande Silvery
    
    Minnow, 601 F.3d at 1117-18
    . Finally, because we also continue to address NMHC’s
    challenges to the 2014, 2015, and 2016 rules, any concern about “gamesmanship” is
    unwarranted.
    38
    Because NMHC’s challenges to the 2017 and 2018 rules are moot, we do not
    address them in our following merits discussion. We remand NMHC’s challenges to
    the 2017 and 2018 rules to the district court with instructions to vacate its judgment
    as to those rules for lack of jurisdiction.
    III. NMHC’S CHALLENGE TO THE 2014, 2015, AND 2016 RULES
    The district court vacated and remanded HHS’s 2014, 2015, 2016, 2017, and
    2018 risk adjustment rules. Due to our mootness determination, we limit our review
    to the 2014, 2015, and 2016 rules. We reverse the district court’s summary judgment
    ruling in favor of NMHC regarding these rules. As a result, we need not address
    whether the district court erred in ordering vacatur or in denying HHS’s Rule 59(e)
    motion.
    A. Legal Background
    Under the APA, a reviewing court shall “hold unlawful and set aside agency
    action . . . found to be arbitrary, capricious, an abuse of discretion, or otherwise not
    in accordance with law.” 5 U.S.C. § 706(2)(A).
    In reviewing an APA challenge to agency action, a district court acts as an
    appellate court. See S. Utah Wilderness All. v. Dabney, 
    222 F.3d 819
    , 823 n.4 (10th
    Cir. 2000). The court employs summary judgment to “decid[e], as a matter of law,
    whether the agency action is supported by the administrative record and otherwise
    consistent with the APA standard of review.” Calloway v. Harvey, 
    590 F. Supp. 2d 29
    , 36 (D.D.C. 2008) (quotations omitted); see Olenhouse v. Commodity Credit
    39
    Corp., 
    42 F.3d 1560
    , 1576 (10th Cir. 1994) (“[T]he district court itself must examine
    the administrative record and itself must find and identify facts that support the
    agency’s action.”). 22
    On appeal to this court, we review “de novo a district court’s decision in an
    APA case,” Biodiversity Conservation All. v. Jiron, 
    762 F.3d 1036
    , 1059 (10th Cir.
    2014), and consider “the administrative record directly,” Stand Up for California! v.
    U.S. Dep’t of Interior, 
    879 F.3d 1177
    , 1181 (D.C. Cir. 2018). “In reviewing the
    agency’s action, we must render an independent decision using the same standard of
    review applicable to the [d]istrict [c]ourt[’s]” review. 
    Olenhouse, 42 F.3d at 1580
    ;
    see City of Colo. Springs v. Solis, 
    589 F.3d 1121
    , 1131 n.2 (10th Cir. 2009) (focusing
    on Department of Labor decision rather than district court framing in APA challenge
    on appeal). Our review is limited to the administrative record, including “all
    materials compiled by the agency that were before the agency at the time the decision
    was made.” James Madison Ltd. v. Ludwig, 
    82 F.3d 1085
    , 1095 (D.C. Cir. 1996)
    (quotations omitted).
    Although we afford no deference to the district court’s decision, we must do so
    as to HHS’s actions. See W. Watersheds Project v. Bureau of Land Mgmt., 
    721 F.3d 22
             See also 10A Charles Alan Wright & Arthur R. Miller, Fed. Prac. & Proc.
    Civ. § 2725 (4th ed. 2019) (“[W]hen the court is being asked to review an
    administrative record and apply legal standards to that record, summary judgment is
    an appropriate vehicle for deciding the case.”).
    40
    1264, 1273 (10th Cir. 2013). “Our inquiry under the APA must be thorough, but the
    standard of review is very deferential to the agency.” 
    Id. (quotations omitted).
    This
    deference means we may set aside an agency action only if it violates the APA. See
    
    id. HHS’s actions
    are entitled to a presumption of regularity, and NMHC bears the
    burden of persuasion to show HHS acted arbitrarily and capriciously. See
    Biodiversity Conservation 
    All., 762 F.3d at 1060
    .
    An agency’s action is arbitrary and capricious where the agency
    (1) entirely fail[s] to consider an important aspect of the
    problem, (2) offer[s] an explanation for its decision that
    runs counter to the evidence before the agency, or is so
    implausible that it could not be ascribed to a difference in
    view of the product of agency expertise, (3) fail[s] to base
    its decision on consideration of the relevant factors, or (4)
    ma[kes] a clear error of judgment.
    W. Watersheds 
    Project, 721 F.3d at 1273
    (quotations omitted).
    “One of the basic procedural requirements of administrative rulemaking is that
    an agency must give adequate reasons for its decisions.” Encino Motorcars, LLC v.
    Navarro, 
    136 S. Ct. 2117
    , 2125 (2016). “Our scope of review is ‘narrow’: we
    determine only whether the [agency] examined ‘the relevant data’ and articulated ‘a
    satisfactory explanation’ for [its] decision, ‘including a rational connection between
    the facts found and the choice made.’” Dep’t of Commerce v. New York, 
    139 S. Ct. 2551
    , 2569 (2019) (quoting Motor Vehicle Mfrs. Ass’n v. State Farm Mut. Auto. Ins.
    Co., 
    463 U.S. 29
    , 43 (1983)). We “must confine ourselves to ensuring that [the
    agency] remained within the bounds of reasoned decisionmaking.” 
    Id. (quotations 41
    omitted). “But where the agency has failed to provide even that minimal level of
    analysis, its action is arbitrary and capricious . . . .” Encino 
    Motorcars, 136 S. Ct. at 2125
    .
    B. NMHC’s Challenge to the Statewide Average Premium
    The district court decided HHS was arbitrary and capricious because it did not
    explain why the risk adjustment program would be budget neutral. On appeal, as in
    its complaint, NMHC more broadly attacks HHS’s rationale for the statewide average
    premium, which, if meritorious, would be an alternative ground to affirm. In the
    following discussion, we therefore determine that HHS did not act arbitrarily and
    capriciously in using the statewide average premium in its formula for the 2014,
    2015, and 2016 rules. We further address why HHS was not arbitrary and capricious
    for failing to explain why it chose a budget-neutral design.
    Statewide Average Premium
    NMHC challenged “HHS’s decision to use the statewide average premium, as
    opposed to an insurer’s own premium,” in the risk adjustment program. Aplee. Br. at
    20-21. The district court concluded that “HHS’[s] risk adjustment regulations—
    specifically their use of the statewide average premium—are arbitrary and
    capricious.” NMHC I, 
    312 F. Supp. 3d
    at 1205; see also NMHC II, 
    340 F. Supp. 3d
    at 1166 (noting district court “concluded that HHS did not adequately explain its
    decision to employ state average premiums”). NMHC contends that “HHS points to
    nothing in the administrative record to support its use of the statewide average
    42
    premium, and instead relies on impermissible post hoc arguments. . . .” Aplee. Br. at
    23. We disagree. The administrative record is replete with reasoned explanations for
    why HHS chose to use the statewide average premium in its formula.
    As discussed above, HHS researched how to implement the risk adjustment
    program before promulgating the 2014 rule. In its 2011 White Paper, CCIIO
    identified four alternatives for the formula, including the statewide average premium
    and the plans’ own premiums. 2011 White Paper at 14. 23 It described the benefits
    and drawbacks of each alternative and invited the public to comment on them. 
    Id. For example,
    CCIIO noted:
    Option 1a: Weighted [s]tate average premiums. This
    approach would calculate the baseline premium according
    to the enrollment-weighted average premium in the [s]tate.
    The [s]tate average could be calculated with or without
    adjustment for actuarial value of plans. Using a [s]tate
    average (without actuarial value adjustment) would result
    in balanced payments and charges, because the [s]tate
    average is a single dollar amount for all plans, and plan
    risk scores average to 1.0.
    ...
    Option 2: Plan’s own premiums. This approach would use
    each plan’s own premiums as the baseline premium.
    Relative to the prior options, charges would be lowest for
    low premium, low-risk plans under this approach, and
    payments would be highest for high risk, high premium
    plans. In this approach, the amount of charges and
    23
    As previously noted, because NMHC argued only in favor of using the
    plans’ own premiums, we focus on HHS’s choice to use the statewide average
    premium over the plans’ own premiums.
    43
    payments would be affected by each plan’s premium. For
    plans with a sicker than average risk mix, a lower premium
    plan would receive less in payments than a higher premium
    plan, even if the two plans have the same risk level. This
    could create disincentives for high-risk plans to operate
    efficiently or set lower prices. Conversely, among two
    plans with the same healthier than average risk mix, a
    lower premium plan would have lower charges, potentially
    creating incentives for low-risk plans to operate more
    efficiently and/or set lower premiums.
    
    Id. at 14-15.
    It further noted:
    When payments are greater than charges, a low risk plan
    with low premiums would be charged less if the baseline
    premium is the plan’s own premiums and payments are
    reduced to charges, as compared to what the plan would be
    charged if the baseline premium is the [s]tate average
    premium or the baseline premium is the plan’s own
    premiums with charges increased to payments.
    Conversely, a high risk plan with high premiums would
    receive higher payments if the baseline premium is the
    plan’s own premium and charges are increased to
    payments, as compared to the payments the plan would
    receive if the baseline premium is the [s]tate average
    premium, or the baseline premium is the plan’s own
    premiums with payments decreased to charges.
    
    Id. at 16.
    When HHS proposed using the statewide average premium in its 2014
    proposed rule, it relied on research from the 2011 White Paper. See 2014 Proposed
    Rule, 77 Fed. Reg. at 73,139. In a section titled “Rationales for a Transfer
    Methodology Based on State Average Premiums,” HHS explained:
    Risk adjustment transfers are intended to reduce the
    impact of risk selection on premiums while preserving
    premium differences related to other cost factors, such as the
    44
    actuarial value, local patterns of utilization and care delivery,
    local differences in the cost of doing business, and, within
    limits established by the Affordable Care Act, the age of the
    enrollee. Risk adjustment payments would be fully funded by
    the charges that are collected from plans with lower risk
    enrollees (that is, transfers within a [s]tate would net to zero).
    In the [2011] Risk Adjustment White Paper, we
    presented several approaches for calculating risk adjustment
    transfers using the [s]tate average premium and plans’ own
    premiums. The approaches that used plans’ own premiums
    resulted in unbalanced payment transfers, requiring a
    balancing adjustment to yield transfers that net to zero. These
    examples also demonstrated that the balancing adjustments
    could introduce differences in premiums across plans that
    were not consistent with features of the plan (for example,
    AV or differences in costs and utilization patterns across
    rating areas). A balancing adjustment would likely vary from
    year to year, and could add uncertainty to the rate
    development process (that is, plan actuaries would need to
    factor the uncertainty of the balancing adjustment into their
    transfer estimates).
    Therefore, we propose a payment transfer formula that
    is based on the [s]tate average premium for the applicable
    market, as described in section III.B.3.a. of this proposed rule.
    The [s]tate average premium provides a straightforward and
    predictable benchmark for estimating transfers. As shown in
    the examples in the [2011] Risk Adjustment White Paper,
    transfers net to zero when the [s]tate average premium is used
    as the basis for calculating transfers.
    Plan premiums differ from the [s]tate average premium
    due to a variety of factors, such as differences in cost-sharing
    structure or regional differences in utilization and unit costs.
    The proposed payment transfer formula applies a set of cost
    factor adjustments to the [s]tate average premium so that it
    will better reflect plan liability. These adjustments to the
    [s]tate average premium result in transfers that compensate
    plans for liability differences associated with risk selection,
    45
    while preserving premium differences related to the other cost
    factors described above.
    
    Id. In the
    2014 final rule, HHS noted it received comments in support of its decision
    to use the statewide average premium. It said:
    Comment: We received a number of comments in
    support of our proposal to use the [s]tate average premium as
    the basis for risk adjustment transfers. One commenter
    suggested that use of a plan’s own premium may cause
    unintended distortions in the transfer formula. One
    commenter suggested that we use net claims, or approximate
    net claims by using 90 percent of the [s]tate average
    premium, as the basis for risk adjustment transfers.
    Response: The goal of the payment transfer formula
    is, to the extent possible, to promote risk-neutral premiums.
    We agree with commenters that use of a plan’s own premium
    may cause unintended distortions in transfers. We also
    believe that both claims and administrative costs include
    elements of risk selection, and therefore, that transfers should
    be based on the entire premium. We are finalizing our
    proposal to base the payment transfer formula on the [s]tate
    average premium.
    2014 Final Rule, 78 Fed. Reg. at 15,432.
    In sum, HHS explained in the rulemaking proceeding that it chose the
    statewide average premium over alternatives such as the plans’ own premiums to
    (1) “reduce the impact of risk selection on premiums while preserving premium
    differences related to other cost factors,” 2014 Proposed Rule, 77 Fed. Reg. at
    73,139; (2) achieve “a straightforward and predictable benchmark for estimating
    transfers” each year, id.; (3) “promote risk-neutral premiums,” 2014 Final Rule, 78
    46
    Fed. Reg. at 15,432; (4) avert “caus[ing] unintended distortions in transfers,” id.; see
    also 2011 White Paper at 14 (using plans’ own premiums “could create disincentives
    for high-risk plans to operate efficiently or set lower prices”); and (5) avoid
    disproportionately distributing costs to insurers when using balancing adjustments,
    2011 White Paper at 16. A sixth explanation stated that using the statewide average
    premium facilitates budget neutrality, making transfers “net to zero” without
    additional balancing adjustments. 2014 Proposed Rule, 77 Fed. Reg. at 73,139; see
    2011 White Paper at 14. 24
    HHS thus acted reasonably in choosing to use the statewide average premium.
    See Dep’t of 
    Commerce, 139 S. Ct. at 2570
    (“[T]he choice between reasonable policy
    alternatives in the face of uncertainty was the [agency’s] to make.”). It “considered
    the relevant factors, weighed risks and benefits, and articulated [several] satisfactory
    explanation[s] for [its] decision” in the administrative record. 
    Id. No commenter
    challenged HHS’s decision to use the statewide average premium in the 2014, 2015,
    or 2016 rules.
    24
    These explanations overlap in the administrative record. HHS relied on
    similar reasons for the 2015 and 2016 rules. See, e.g., 2015 Final Rule, 79 Fed. Reg.
    at 13,753 (“We proposed to use the [2014] methodology in 2015 . . . .”); 2016 Final
    Rule, 80 Fed. Reg. at 10,760 (“We proposed to continue to use the same risk
    adjustment methodology finalized in the 2014 [rule] . . . .”).
    47
    District Court and Budget Neutrality
    Although the agency provided reasoned explanations for using the statewide
    average premium, the district court thought the agency should further have explained
    the budget-neutral design of the program because it “infect[ed]” HHS’s rationales for
    using the statewide average premium. NMHC I, 
    312 F. Supp. 3d
    at 1209. NMHC
    makes similar arguments in its brief on appeal. We view this issue differently and
    give HHS the deference the APA requires. See W. Watersheds 
    Project, 721 F.3d at 1273
    ; 5 U.S.C. § 706(A)(2). HHS was not arbitrary and capricious in using a budget-
    neutral design for its risk adjustment program in the 2014, 2015, and 2016 rules. 25
    25
    In general, an issue must have been raised before an agency for a party to
    seek judicial review of agency action on that issue. See United States v. L.A. Tucker
    Truck Lines, Inc., 
    344 U.S. 33
    , 36-37 (1952); Ark Initiative v. U.S. Forest Serv., 
    660 F.3d 1256
    , 1261 (10th Cir. 2011). HHS argues that NMHC failed to exhaust any
    challenge to budget neutrality. See Aplt. Br. at 22-23. It points out that no
    commenter objected to the budget-neutral design until the 2018 benefit year. See 
    id. at 22.
    Courts may require issue exhaustion even when, as in this case, neither a
    statute nor a regulation requires it. See Advocates for Highway & Auto Safety v. Fed.
    Motor Carrier Safety Admin., 
    429 F.3d 1136
    , 1148-49 (D.C. Cir. 2005). In this
    context, issue exhaustion is not a jurisdictional prerequisite to judicial review. See
    
    id. at 1148;
    see also Avocados Plus Inc. v. Veneman, 
    370 F.3d 1243
    , 1248 (D.C. Cir.
    2004).
    HHS first raised its issue exhaustion defense in its Rule 59(e) motion, which
    may have been too late under cases like Eaton v. Pacheco, 
    931 F.3d 1009
    , 1028 (10th
    Cir. 2019) (rejecting argument raised “for the first time” in a Rule 59(e) motion). It
    could have raised the defense earlier in response to NMHC’s discussion in its
    summary judgment motion that “there is no statutory requirement that risk
    adjustment be budget neutral.” Dist. Ct. Doc. 33 at 22. But this discussion was part
    of a broader argument about the statewide average premium. And HHS may not have
    expected the district court to rely so heavily on budget neutrality for its summary
    judgment ruling. So it is not clear whether HHS should be faulted for its late-
    blooming issue-exhaustion defense.
    48
    As an initial matter, the district court found HHS was arbitrary and capricious
    for failing to explain “whether budget neutrality was sound public policy.” NMHC I,
    
    312 F. Supp. 3d
    at 1210. But in its complaint, NMHC challenged HHS’s use of the
    statewide average premium, not HHS’s budget-neutral design of the program. See
    Dist. Ct. Doc. 33 at 22. And on appeal, NMHC continues to challenge HHS’s
    “decision to use the statewide average premium instead of each issuer’s own
    premium.” Aplee. Br. at 19-22. Rather than address whether HHS adequately
    explained why it chose the statewide average premium, the court addressed whether
    HHS provided a rationale for the budget-neutral design. Apart from this discrepancy,
    HHS was not arbitrary and capricious in using a budget-neutral design.
    First, the district court determined “HHS’[s] justifications for using the
    statewide average premium instead of a plan’s own premium all assume that the ACA
    requires risk adjustment to be budget neutral, which is not correct.” NMHC I, 312 F.
    Supp. 3d at 1205. As the district court noted, the ACA neither requires nor forbids
    budget neutrality. 
    Id. at 1209;
    see 42 U.S.C. § 18063. But the administrative record
    We think the better course is to address the merits of the district court’s
    analysis of budget neutrality. In addition to arguing issue exhaustion, HHS also
    contends it complied with the APA in designing the risk adjustment program based
    on budget neutrality. See Aplt. Br. at 26-34. Because we disagree with the district
    court’s analysis of budget neutrality, we need not resolve the matter of issue
    exhaustion. The allegedly unexhausted issue fails on the merits. See Lincoln v.
    BNSF Ry. Co., 
    900 F.3d 1166
    , 1199-1200 (10th Cir. 2018) (considering merits of
    unexhausted claims on appeal where EEOC exhaustion was non-jurisdictional). Any
    resolution of HHS’s issue-exhaustion argument thus would not affect the outcome of
    this appeal.
    49
    shows HHS would have designed its program to be budget neutral even if it had used
    the plans’ own premiums rather than the statewide average premium in its formula.
    See 2011 White Paper at 15 (“Since payment and charge transfers will be budget
    neutral, a method is needed to balance them if payments are greater than charges or
    vice versa.”).
    Second, the district court determined HHS could have justified using budget
    neutrality as a “worthy policy goal” but failed to make “such a determination in the
    record.” NMHC I, 
    312 F. Supp. 3d
    at 1205. But budget neutrality was not a policy
    goal. It was the product of funding constraints. The statute that created the program
    lacked any funding authorization. 26 NMHC has never pointed to an explicit
    congressional appropriation for the program. 27 The absence of an appropriation was
    26
    Compare 42 U.S.C. § 18063 (not authorizing appropriations for ACA’s risk
    adjustment program) with 
    id. § 1395w-115(a)
    (establishing “budget authority in
    advance of appropriations Acts” for risk-adjusted payments under Medicare Part D)
    and 
    id. § 18042(g)
    (authorizing appropriations in ACA to provide loans to qualified
    health insurers).
    27
    NMHC argues HHS could have used funds appropriated for CMS’s “other
    responsibilities.” See Aplee. Br. at 30; see, e.g., Dep’t of Health & Human Servs.
    Appropriations Act, 2014, Pub. L. No. 113-76, 128 Stat. 5, 374-75. But, as HHS
    explains, to enable health insurers to plan with more certainty, it announced the risk
    adjustment rules before these funds were appropriated. See Aplt. Br. at 30-31; Aplt.
    Reply Br. at 8; see also 
    Minuteman, 291 F. Supp. 3d at 202-03
    . HHS further points
    out that Congress authorized the states to implement the program and did not
    authorize funding for the states. See 42 U.S.C. § 18063.
    NMHC also argues that “user fees” were available for the program. See Aplee.
    Br. at 30; Oral Arg. at 26:20-27:13. Although fees were used to cover HHS’s
    administrative costs for the exchanges and the risk adjustment program, they were
    not used for the payments made to high-risk insurers. See, e.g., 2014 Final Rule, 78
    50
    a matter of public record. See, e.g., Dep’t of Health & Human Servs. Appropriations
    Act, 2014, Pub. L. No. 113-76, 128 Stat. 5, 363-88; Dep’t of Health & Human Servs.
    Appropriations Act, 2015, Pub. L. No. 113-235, 128 Stat. 2130, 2466-93; Dep’t of
    Health & Human Servs. Appropriations Act, 2016, Pub. L. No. 114-113, 129 Stat.
    2242, 2600-27. This is likely why no one questioned the budget-neutral design
    during notice-and-comment rulemaking until 2018. 28
    HHS did not violate the APA when it designed the risk adjustment program as
    budget neutral. It lacked funding to do otherwise. The APA’s requirement that an
    agency explain its decision applies when the agency exercises its discretion. See
    State 
    Farm, 463 U.S. at 48
    (“[A]n agency must cogently explain why it has exercised
    its discretion in a given manner . . . .” (emphasis added)); see also United States v.
    Magnesium Corp. of Am., 
    616 F.3d 1129
    , 1144 (10th Cir. 2010) (same). Here, there
    was no exercise of discretion to explain. In hindsight, perhaps the agency should
    have explained more fully why it developed a program in which the risk adjustment
    Fed. Reg. at 15,412, 15,416-17 (“[T]he risk adjustment user fee [is collected] for the
    sole purpose of funding HHS’s costs for operating the [f]ederal risk adjustment
    program . . . .”). To the extent NMHC contends that the charges imposed on low-risk
    insurers can be characterized as user fees, using them to make transfer payments is
    compatible with a budget neutral program.
    28
    At least one commenter challenged the budget-neutral design of the program
    in 2018. See 2018 Final Rule, 81 Fed. Reg. at 94,101. We do not consider comments
    made in the notice-and-comment proceedings for the 2018 rule because NMHC’s
    challenge to that rule is moot.
    51
    charges and payments netted to zero, such as the rationale for budget neutrality that
    HHS articulated for the new 2018 rule. But it hardly follows that the agency acted
    unreasonably. HHS’s actions did not violate the arbitrary and capricious standard.
    To the extent the district court’s opinion can be read as criticizing HHS’s
    reasons apart from budget neutrality, see NMHC I, 
    312 F. Supp. 3d
    at 1211-12, our
    previous analysis addresses why the agency was not arbitrary and capricious in
    choosing the statewide average premium. 29 Courts cannot “second[]guess” an
    agency’s rulemaking decision when it provided “reasons for [its] chosen course of
    action.” Dep’t of 
    Commerce, 139 S. Ct. at 2571
    . HHS was not arbitrary or
    capricious in choosing to use the statewide average premium in its formula.
    IV. CONCLUSION
    We remand NMHC’s challenges to the 2017 and 2018 rules to the district
    court with instructions to vacate its judgment as to those rules for lack of jurisdiction
    due to mootness and to dismiss those claims without prejudice. We reverse the
    29
    The district court said HHS did not adequately explain why the statewide
    average premium is better than the plans’ premiums to determine risk and encourage
    plans to enroll sicker individuals. See NMHC I, 
    312 F. Supp. 3d
    at 1211-12. NMHC
    makes similar arguments on appeal. See Aplee. Br. at 32-37. But HHS explained
    that use of the statewide average premium avoids the need for a “balancing
    adjustment,” which would contribute to uncertainty and premium variation unrelated
    to risk. See 2014 Proposed Rule, 77 Fed. Reg. at 73,139. HHS further explained that
    using the plans’ premiums to determine transfer payments would allow plans to seek
    higher payments by operating less efficiently rather than accepting high-risk
    enrollees. See 2011 White Paper at 14; see also 2014 Final Rule, 78 Fed. Reg. at
    15,432. Unlike the district court, we defer to the agency’s explanations.
    52
    district court’s summary judgment ruling for NMHC as to the 2014, 2015, and 2016
    rules. 30
    30
    Because we reverse the district court’s ruling that HHS violated the APA,
    we need not address the court’s decision to remand with vacatur or the court’s denial
    of HHS’s Rule 59(e) motion.
