Garland, Chief Judge

Seeking to increase its capital reserves, the Options Clearing Corporation proposed a change in its rules. That change was subject to approval by the Securities and Exchange Commission, which granted approval without itself making the findings and determinations prescribed by the Securities Exchange Act of 1934. Instead, it effectively abdicated that responsibility to the Corporation. Because this does not represent the kind of reasoned decisionmaking required by either the Exchange Act or the Administrative Procedure Act, we remand the case to the Commission for further proceedings.

I

The Options Clearing Corporation (OCC), a Delaware corporation, is a clearing agency that facilitates trades in options and other financial instruments. It is the only clearing agency for standardized U.S. options listed on U.S. national securities exchanges. Given its significant role, OCC has been designated a systemically important financial market utility and is closely regulated by the Securities and Exchange Commission (SEC). See Order Approving Proposed Rule Change Concerning the Options Clearing Corporation's Capital Plan, 81 Fed. Reg. 8294, 8294 (Feb. 18, 2016) ("Order").

At the time of the events in this case, there were twelve national securities exchanges on which listed options were traded. Five were equal shareholders in OCC; seven were nonshareholders, lacking any ownership interest. All of the exchanges clear their trades in listed options through OCC. In addition to the exchanges, OCC has "clearing members" that clear and settle options trades for their customers through the exchanges. See Order, 81 Fed. Reg. at 8294 ; OCC, Bylaws Art. V (amended 2009).OCC charges clearing members fees for the transactions they make. For each upcoming year, OCC sets the fees to cover the year's projected expenses, plus a buffer. If, at the end of the year, OCC has taken in more fees than needed to cover its expenses and maintain its reserves, it refunds the excess fees to the clearing members, allocated in proportion to what they had paid. Until the developments at issue here, OCC refunded all such excess fees. See Notice of Filing of a Proposed Rule Change Concerning a Proposed Capital Plan, 80 Fed. Reg. 5171, 5175 (Jan. 30, 2015) ("Notice of Proposed Rule Change").

This case concerns OCC's attempt to boost its capital reserves and, in order to do so, to alter how fees and refunds are calculated. In 2014, OCC began evaluating its capital level and eventually determined that it did not have enough to cover "business, operational, and pension risks." Order, 81 Fed. Reg. at 8296. While these capital needs exclude counterparty and on-balance-sheet risks, which are covered by billions of dollars in other funds, they are still significant. OCC determined that on top of its existing capital reserves of $25 million, it needed an additional $222 million of capital immediately on hand, plus another $117 million in backup "Replenishment Capital" that it could call upon if necessary. See Notice of Proposed Rule Change, 80 Fed. Reg. at 5172 ; Order, 81 Fed. Reg. at 8295-96.

To amass those reserves, OCC developed a Capital Plan. Under the Plan, OCC's five shareholder exchanges would make immediate capital contributions to reach OCC's current capital target and also pledge to provide Replenishment Capital upon request. The Plan compensates those contributions with dividends paid out of OCC's fees. In particular, after fees are applied to OCC's operating expenses, and then used to restore capital reserves if they have dipped, the remaining unused fees are split between dividends and refunds. Approximately half of the unused fees go to shareholders as dividends; approximately half are refunded to clearing members. In other words, whereas clearing members previously received all of the excess fees as refunds, the Plan diverts roughly half of those refunds to dividends. See Notice of Proposed Rule Change, 80 Fed. Reg. at 5173-75.

The Plan makes other changes to OCC's fee practices as well. The buffer used to calculate each year's fees—that is, the amount by which that year's projected expenses are inflated to arrive at the amount to be charged as upfront fees—decreases under the Plan from 31% to 25%. And the Plan provides for a permanent end to refunds (but not dividends) if Replenishment Capital becomes necessary and is not repaid in 24 months or if the target capital requirement is not restored within that period. See id.

OCC's Plan cannot go into effect unless approved by the SEC because OCC is a "self-regulatory organization" under the Securities Exchange Act of 1934, 15 U.S.C. § 78a et seq . ("Exchange Act"). In early 2015, OCC brought its Plan to the SEC, which published a Notice of Filing of a Proposed Rule Change and solicited public comments. The SEC issued a final Order approving the Plan in early 2016. See Order, 81 Fed. Reg. at 8294-95.

Petitioners—two nonshareholder exchanges (Miami International Securities Exchange, LLC and BOX Options Exchange LLC), a clearing member (KCG Americas LLC, a subsidiary of Petitioner KCG Holdings), and a market participant (Susquehanna International Group, LLP)—sought judicial review. They also moved to stay the SEC's Order to prevent the OCC's Plan from going into effect, but a panel of this court denied the stay. Susquehanna Int'l Grp., LLP v. SEC , No. 16-1061 (D.C. Cir. Feb. 23, 2016) (order denying motion for stay). As a consequence, OCC currently operates according to the Plan.

II

We have jurisdiction to review the SEC's Order pursuant to 15 U.S.C. § 78y(a)(3). We review the Order under the Administrative Procedure Act (APA), which requires us to hold unlawful agency action that is "arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law" or that is "unsupported by substantial evidence." 5 U.S.C. § 706(2)(A), (E) ; see 15 U.S.C. § 78y(a)(4) ; NetCoalition v. SEC , 615 F.3d 525, 532 (D.C. Cir. 2010). To satisfy the "arbitrary and capricious" standard, "the agency must examine the relevant data and articulate a satisfactory explanation for its action including a ‘rational connection between the facts found and the choice made.’ " Motor Vehicle Mfrs. Ass'n v. State Farm Mut. Auto. Ins. Co. , 463 U.S. 29, 43, 103 S.Ct. 2856, 77 L.Ed.2d 443 (1983) (quoting Burlington Truck Lines, Inc. v. United States , 371 U.S. 156, 168, 83 S.Ct. 239, 9 L.Ed.2d 207 (1962) ).

OCC is registered as a clearing agency with the SEC, and is therefore classified as a "self-regulatory organization." See 15 U.S.C. §§ 78c(a)(26), 78q-1(b). The SEC "shall approve" a self-regulatory organization's proposed rule change only "if it finds that such proposed rule change is consistent with" provisions of the Exchange Act. Id. § 78s(b)(2)(C)(i); see id. § 78s(b)(2)(C)(ii). In turn, a clearing agency's rules are consistent with the Act only if "the Commission determines that" they meet certain specified requirements. Id. § 78q-1(b)(3). Petitioners argue that the SEC erred in approving OCC's Plan because it does not meet several of those requirements.

First, the Exchange Act requires that a clearing agency's rules "not impose any burden on competition not necessary or appropriate in furtherance of the purposes of" the Act. Id. § 78q-1(b)(3)(I). Petitioners object that the Plan overcompensates shareholder exchanges, which unjustifiably burdens competition by nonshareholders. See Pet'rs' Br. 24.

Second, the Act requires that a clearing agency's rules be "designed ..., in general, to protect investors and the public interest." Id. § 78q-1(b)(3)(F). Petitioners contend that the Plan harms investors and the public by transforming OCC from a public utility to a profit-seeking monopoly and by increasing the fees charged to OCC's customers. See Pet'rs' Br. 33-40.

Third, the same subsection requires that rules not be "designed to permit unfair discrimination ... among participants in the use of the clearing agency." 15 U.S.C. § 78q-1(b)(3)(F). Petitioners maintain that the Plan unfairly discriminates between shareholder exchanges and nonshareholder exchanges by denying nonshareholders the opportunity to contribute capital in exchange for dividends. Petitioners argue further that the Plan discriminates between shareholder exchanges and clearing members by denying clearing members compensation for the capital they contribute as fees. See Pet'rs' Br. 41-43.

Fourth, the Act requires that a self-regulatory organization "comply with ... its own rules." 15 U.S.C. § 78s(g)(1). OCC's bylaws provide that nonshareholder exchanges "will be promptly provided with information that [OCC's] Executive Chairman considers to be of competitive significance" and that a "requesting [nonshareholder exchange] shall be afforded the opportunity to make presentations" to OCC's Board or to a committee of the Board. OCC, Bylaws Art. VIIB, Interpretations & Policies § 1.01, .02 (§ 1.01 amended 2014; § 1.02 adopted 2002). Petitioners object that OCC violated both provisions by failing to notify nonshareholder exchanges while OCC was developing the Plan. See Pet'rs' Br. 43-48.

We do not reach any of those arguments, all of which contend that the OCC's Plan is inconsistent with the above-described requirements of the Exchange Act. We do not reach them because, as Petitioners also argue, the SEC's Order approving the Plan fails in a more basic respect: the Commission did not itself "find[ ]" or "determin[e]," 15 U.S.C. §§ 78q-1(b)(3), 78s(b)(2)(C)(i), that the Plan met any of those requirements. Instead, the SEC effectively abdicated that responsibility to OCC—the proponent of the Plan and the entity whose rule changes the SEC is statutorily obligated to approve or disapprove, id. § 78s(b)(2)(C)(i), (ii). Moreover, the SEC's Order reflects little or no evidence of the basis for the OCC's own determinations—and few indications that the SEC even knew what that evidence was.

We have rejected this kind of agency "decisionmaking" before. In Gerber v. Norton , we held:

When a statute requires an agency to make a finding as a prerequisite to action, it must do so. Merely "[r]eferencing a requirement is not the same as complying with that requirement." ... Nor may the agency delegate its responsibility to the regulated party. See State of Idaho v. ICC , 35 F.3d 585, 596 (D.C. Cir. 1994) (holding that the ICC failed to meet its responsibilities under [the National Environmental Policy Act] by "deferr[ing] not only to the judgments of other agencies, but also to that of Union Pacific, the licensee").

294 F.3d 173, 185-86 (D.C. Cir. 2002) (quoting Sugar Cane Growers Coop. v. Veneman , 289 F.3d 89, 97 (D.C. Cir. 2002) ). To be sure, SEC appellate counsel acknowledges that the SEC cannot "simply accept what [a self-regulatory organization] has done," but rather is "obligated to make an independent review." Oral Arg. Tr. 24. And the SEC's Order states that the Commission did make the necessary findings. See Order, 81 Fed. Reg. at 8300-04. But " ‘[s]tating that a factor was considered’—or found—‘is not a substitute for considering’ or finding it." Gerber , 294 F.3d at 185 (quoting Getty v. Fed. Savings & Loan Ins. Corp. , 805 F.2d 1050, 1055 (D.C. Cir. 1986) ). As explained below, stating, not finding, is what the Commission did here.

A

The Order's shortcomings are apparent in its discussion of whether the Plan pays dividends to shareholder exchanges at a reasonable rate. That is a central issue: if the dividend rate represents an unnecessary windfall for shareholders, as Petitioners argue, then the Plan may run afoul of the Exchange Act's prohibitions by unnecessarily or inappropriately burdening competition, harming the interests of investors and the public, or unfairly discriminating against nonshareholders and clearing members. See 15 U.S.C. § 78q-1(b)(3)(F), (I). The SEC found that the Plan heeds those statutory prohibitions because the dividends represent a reasonable return on the shareholders' capital contribution. See Order, 81 Fed. Reg. at 8301-03 (declaring that the dividend level is "appropriate" as "compensation" for the costs and risks incurred by the shareholders).Why did the SEC find the return reasonable? The Order says only that the Plan is "designed to set the dividends ... at a level that [OCC's] Board, with the assistance of independent outside financial experts, has determined to be reasonable for the cost and risks associated" with the shareholders' obligations. Id. at 8300.

That explanation raises more questions than it answers. Who were those independent experts? How does the SEC know they were independent? What analysis did they and OCC's Board perform? How did they measure the "level" of the dividends? How did they measure the "cost and risks"? And how did they determine that the dividend level was reasonable for the associated cost and risks? The Order is silent on all counts. Instead, the SEC candidly admits that it simply "rel[ied] on the Board's analysis" of "the rate of return the Stockholder Exchanges were receiving for their capital investment." SEC Br. 30. That is, to decide whether the dividend level was reasonable, the SEC took OCC's word for it.

This is not the reasoned analysis that the Exchange Act and the APA require. The Exchange Act permits the SEC to approve OCC's proposed rule change only "if it finds that" the proposal is consistent with the requirements of the Act. 15 U.S.C. § 78s(b)(2)(C)(i), (ii). That is possible only if the SEC "determines that" the rule complies with specified requirements, 15 U.S.C. § 78q-1(b)(3). Thus, to approve the Plan, the SEC must make "find[ings]" and "determin[ations]"—not merely accept those made by OCC. See Gerber , 294 F.3d at 185.

Nor may the SEC reach a conclusion that is "unsupported by substantial evidence" or "arbitrary [and] capricious." 5 U.S.C. § 706(2)(A), (E) ; 15 U.S.C. § 78y(a)(4). That was the flaw that led us to vacate an SEC order approving a self-regulatory organization's proposed rule change in NetCoalition , 615 F.3d at 537-44. There, we faulted the SEC for reaching a conclusion despite a "lack of support in the record." Id. at 541. The SEC had tried to rely on statements by the self-regulatory organization, but we saw "little" supporting value in the "self-serving views of the regulated entit [y]." Id. Here, too, the SEC's unquestioning reliance on OCC's defense of its own actions is not enough to justify approving the Plan. Instead, the SEC should have critically reviewed OCC's analysis or performed its own. See Bradford Nat'l Clearing Corp. v. SEC , 590 F.2d 1085, 1113-14 (D.C. Cir. 1978) (finding the SEC's reasoning inadequate when it approved registration of a clearing agency by deferring to the clearing agency's "business judgment" on an issue governed by the Act).

On appeal, the SEC defends the Order's approach to the dividend rate in several ways. The SEC's principal argument is that it was reasonable for it to trust "the process" undertaken by OCC. Oral Arg. Tr. 20, 29. Restating the words of the Order, the SEC's brief says that the process included "independent analysis" by outside consultants. SEC Br. 31. But the SEC does not appear to have identified the consultants or seen their analysis, so it came as no surprise that the SEC disclaimed reliance on that outside analysis at oral argument. Oral Arg. Tr. 18. Instead, the SEC ultimately relies on another aspect of OCC's decisionmaking process: what it describes as "arm's-length negotiations" between those OCC Board directors who represented clearing members and those who represented shareholders, which culminated in a "supermajority" Board vote in favor of the plan. SEC Br. 31, 38 & n.16; see also Oral Arg. Tr. 19-20.

"Trust the process" may be a reasonable slogan for the hometown basketball team of lead petitioner Susquehanna International Group. But the process alone cannot justify the dividend rate in this case. For one thing, it is hardly accurate to describe the negotiations between Board members as "arm's length." OCC's shareholders have effective veto power over certain proposals, giving them outsize bargaining power compared to clearing members represented on the Board. See Letter from James E. Brown, Executive Vice President, OCC, to Brent J. Fields, Secretary, SEC at 6 n.10 (Feb. 23, 2015) (J.A. 85 n.10). Indeed, only four of nine directors representing clearing members voted in favor of the Plan, see id. at 7 n.12 (J.A. 86 n.12), making it less than clear that the process struck an appropriate balance between the interests of shareholders and clearing members. What is more, not all of the interested parties were even part of the negotiations among Board members. Only a small fraction of clearing members are on the Board, and none of the nonshareholder exchanges are. See Order Approving Proposed Rule Change Concerning a Proposed Capital Plan, 80 Fed. Reg. 13058, 13060 n.8 (Mar. 12, 2015). So, as to any agreement between OCC and shareholders regarding the dividend rate, the shareholder exchanges were on both sides of the transaction (because they were both OCC Board members and recipients of the dividends), while nonshareholder exchanges were on neither.

More fundamentally, the SEC cannot rely on OCC's process totally divorced from any examination of the substance of the Plan, especially when the procedural features that the SEC cites are little more than the general elements of OCC's governance structure. Indeed, were we to accept this justification, that would mean the SEC could or should approve nearly any plan OCC proposes—hardly the result the Exchange Act envisions. See, e.g. , 15 U.S.C. § 78s(b)(2)(C)(i), (ii) ("The Commission shall disapprove a proposed rule change of a self-regulatory organization if it does not make a finding" that "such proposed rule change is consistent with the requirements of" the Act.).

The SEC also defends its approval of the Plan's dividend rate by arguing that the Plan's structure guarantees reasonable dividends. See Order, 81 Fed. Reg. at 8301 ("The Commission believes that various components of the Capital Plan operate to set reasonable dividends for the cost and risks associated with the Stockholder Exchanges' contributed and committed capital."); id. at 8303 ; Oral Arg. Tr. 21. In particular, the SEC notes that the Plan sets fees based on a fixed percentage of projected costs, and allocates unused fees between dividends and refunds in a fixed proportion. Those inputs, the SEC argues, ensure that the dividend rate will turn out to be reasonable. Oral Arg. Tr. 21, 23.

That reasoning begs the question. The resulting dividend rate will only be reasonable if the Plan's structure (most significantly, the portion of unused fees allocated to dividends) is reasonable. But the Order does not analyze whether—or explain why—it is reasonable to allocate roughly half of unused fees to dividends, as opposed to using a different percentage or a formula other than a fixed proportion of unused fees. In other words, the SEC defends its unquestioning reliance on OCC's claim that the dividend rate is reasonable by its unquestioning reliance on OCC's claim that the Plan's structure is reasonable. That is no defense at all.B

The SEC's lack of reasoned decisionmaking in assessing the dividend rate is enough to make its Order arbitrary and capricious. But that is not the Order's only flaw. A similar lack of reasoned decisionmaking recurs throughout the Order, including in the four additional instances that follow.

First, the Order fails to support its conclusion that the Plan's capital target is reasonable. Commenters disputed whether the Plan raises a reasonable amount of capital at a reasonable pace (as OCC argues), or raises more capital more quickly than OCC actually needs (as Petitioners argue). As with the dividend-rate issue, the Order adopts OCC's claims at face value. The Order accepts that the target is "appropriately designed" simply because "OCC represents that it used various measures and took a methodical and reasoned approach." Order, 81 Fed. Reg. at 8301 (emphasis added); see also id. at 8300 ("The [OCC] Board determined that the historical practice ... did not allow OCC to reach adequate capitalization." (emphasis added)). The Order then relies on that representation in finding the Plan consistent with the Act. See id. at 8301 (concluding that the Plan's capital target is not excessive and hence does not burden competition more than "necessary or appropriate," 15 U.S.C. § 78q-1 (b)(3)(I) ); id. at 8300-01 (concluding that the Plan's capital target is appropriately "designed ... to protect investors and the public interest," § 78q-1(b)(3)(F) ).

In the Order, the SEC states that it "review[ed] the process used by OCC to establish" the target. Order, 81 Fed. Reg. at 8301. But what was that process? OCC states that "[a]n outside consultant conducted a ‘bottom-up’ analysis of OCC's risks" and, "[b]ased on internal operational risk scenarios and loss modeling," OCC quantified its operational and pension risk. Notice of Proposed Rule Change, 80 Fed. Reg. at 5172-73. But since there is no indication that the SEC knew who the consultant was, what analysis he or she conducted, or what additional analysis OCC performed, the Commission was in no position to make a reasoned finding that OCC's process was sound—let alone that the resulting capital target was reasonable. In short, the SEC's Order reflects the same lack of reasoned decisionmaking when assessing the capital target as it displays when assessing the dividend rate. "Trusting the process" is simply not enough.

Second, the SEC was also too quick to accept OCC's claims that the Plan would not increase fees for customers. In determining that the Plan is designed to protect investors and the public interest, 15 U.S.C. § 78q-1(b)(3)(F), the SEC's Order relies on the proposition that the Plan will "allow [ ] generally lower fees," Order, 81 Fed. Reg. at 8301, or at least will not make higher fees "inevitable," id . To support that proposition, the Order only addresses the Plan's lowering of upfront fees—that is, the amount OCC initially charges clearing members, before refunding excess fees at the end of each year. It does not take into account the Plan's reduction of year-end refunds. Taking both into account, Petitioners argue that the Plan harms investors and the public by driving up net fees. Pet'rs' Br. 37 & n.20.

The only thing the Order says to justify ignoring net fees in favor of focusing on upfront fees is that the Plan is "designed to give market participants the benefit of lower upfront transaction costs, especially those customer end users who do not receive passed through refunds from the clearing member." Order, 81 Fed. Reg. at 8302-03 (emphasis added). The underlying assumption of this justification must be that there are so few market participants who do receive passed-through refunds that net fees are irrelevant. But the SEC's Order does not provide record support for that assumption. Instead, it cites, see id. at 8303 n.127, a portion of the Notice of Filing of a Proposed Rule Change, prepared by OCC, stating that "OCC is aware that a portion—possibly a significant portion—of those refunds are not passed through by the clearing members to their end user customers." 80 Fed. Reg. at 5175. That is, the SEC Order's only basis for not taking passed-through refunds into account is a statement by OCC, prepared to justify OCC's own proposal, that a "possibly" significant portion of refunds are not passed through. That does not qualify as a "satisfactory explanation," State Farm , 463 U.S. at 43, 103 S.Ct. 2856. See NetCoalition , 615 F.3d at 540-41 (criticizing the SEC's reliance on the "self-serving views of the regulated entities" in that case).

Third, the Order fails to give any explanation at all for rejecting one of Petitioners' objections. Petitioners charged the Plan with unfair discrimination for treating refunds to clearing members differently from dividends to shareholders under the following scenario: If Replenishment Capital becomes necessary and is not repaid in 24 months (or if the target capital requirement is not restored in the same period), refunds will end permanently but dividends can resume. See Notice of Proposed Rule Change, 80 Fed. Reg. at 5174-75 (explaining this feature); Letter from James E. Brown, Executive Vice President, OCC, to Brent J. Fields, Secretary, SEC at 4-5 (Feb. 24, 2015) (J.A. 105-06) (discussing objections). The Order does not explain why that criticism is unavailing. In fact, as the SEC concedes, the Order misstates the Plan feature at issue, incorrectly explaining at one point that both refunds and dividends will end permanently if Replenishment Capital goes unpaid for 24 months. Order, 81 Fed. Reg. at 8297 ; Oral Arg. Tr. 13-14 (concession by SEC counsel that "that is mistaken"). Hence, not only does the Order give no indication that the SEC analyzed this Plan feature for compliance with the Act, but it instead suggests that the SEC may have misunderstood the feature entirely. That double deficiency demonstrates a lack of reasoned decisionmaking.

Finally, the Order gives short shrift to Petitioners' objection that OCC, by failing to notify nonshareholder exchanges earlier in its development of the Plan, violated its own bylaws. Primarily at issue is OCC's bylaw requirement that nonshareholder exchanges "be promptly provided with information that [OCC's] Executive Chairman considers to be of competitive significance." OCC, Bylaws Art. VIIB, Interpretations & Policies § 1.01 (amended 2014). Despite recognizing that there was a dispute over whether the Plan was competitively significant, the Order merely notes that "OCC represented that it" had "completed all action required to be taken under its ... bylaws." Order, 81 Fed. Reg. at 8305. On remand, the SEC must resolve Petitioners' argument that OCC could not reasonably have considered the Plan to be competitively insignificant. Or, if the SEC concludes that this does not matter, it must give a reasoned explanation why.

III

Having concluded that the SEC's Order is arbitrary and capricious, unsupported by substantial evidence, and otherwise not in accordance with law, we are left with the question of the proper remedy. "An inadequately supported rule ... need not necessarily be vacated." Allied-Signal, Inc. v. U.S. Nuclear Regulatory Comm'n , 988 F.2d 146, 150 (D.C. Cir. 1993). "The decision whether to vacate depends on ‘the seriousness of the order's deficiencies (and thus the extent of doubt whether the agency chose correctly) and the disruptive consequences of an interim change that may itself be changed.’ " Id. at 150-51 (quoting Int'l Union, UMW v. Fed. Mine Safety & Health Admin. , 920 F.2d 960, 967 (D.C. Cir. 1990) ).

Here, the SEC may be able to approve the Plan once again, after conducting a proper analysis on remand. Moreover, unwinding the Plan in the interim would be—in Petitioners' own words—a "logistical nightmare." Pet'rs' Emergency Mot. for Stay 9. Indeed, the parties may well awaken from that nightmare just as the SEC decides to rewind the unwinding.

Thankfully, we can avoid that restless night. The SEC and OCC assure us that it will be possible to unwind the Plan at a later time, see SEC's Opp'n to Pet'rs' Emergency Mot. for Stay 2-3; Oral Arg. Tr. 12 (SEC); id. at 33-34 (OCC), and no party contends that the task would be materially more difficult if done then rather than now. Thus, with no immediate need to vacate the Order, we will remand the case to give the SEC an opportunity to properly evaluate the Plan. See Allied-Signal, Inc. , 988 F.2d at 151 (remanding rather than vacating "because of the possibility that the Commission may be able to justify the Rule, and the disruptive consequences of vacating").

So ordered.
