Although legal remedies exist for the alleged wrongs committed by Electronic Data Systems (“EDS”) and its associated defendants for allegedly mismanaging the *303company’s 401 (k) Retirement Plan, the Rule 23(b)(1) or (b)(2) class action certified by the district court is not among them. The district court erroneously interpreted the impact, inter alia, of intraclass conflicts and fact-specific defenses arising from ERISA § 404(c) and individual releases. Rule 23(b)(2) is unsuited to provide classwide relief, and Rule 23(b)(1) is conceptually unclear. As a result, we must VACATE and REMAND the class certification for further consideration.
I. BACKGROUND
Plaintiffs are current and former employees of EDS1 who participated in the company’s 401(k) defined contribution Retirement Plan (“Plan”).2 Like many employers, EDS offers its employees a menu of retirement options and agrees to match a portion of each employee’s annual contribution to his 401(k) account. Participants then select their individual portfolios and decide when and whether to change the mix of investments. Participant accounts, commingled for management purposes, become the assets of the Plan. The Plan’s trustees, who are subject to the rigorous fiduciary requirements of ERISA, manage the Plan, select and monitor the investment options, and handle each Participant’s account. Significantly, the Plan also invokes ERISA § 404(c), which relieves plan fiduciaries of liability for any loss or breach “which results from such participant’s or beneficiary’s exercise of control [over the assets in his account].” 29 U.S.C. § 1104(c). The tension between the fiduciary obligations and the employee-directed nature of the accounts provides the backdrop to the instant case.
During the class period, EDS offered Plan Participants between thirteen and eighteen investment options, including an EDS Stock Fund.3 Plan documents discussed the different funds, explained that employees could direct contributions to a fund or funds of their choice, and rated the fund options on a scale of one to five for risk (one being the least risky and five being the riskiest). Plan documents rated the EDS Stock Fund as “5 + ” on the risk scale and warned Participants that investing in only one stock violated the diversification principle of portfolio management.4 The Plan documents also explained that EDS agreed to match up to twenty-five percent of each employee’s annual investment, up to six percent of salary, with an investment in the EDS Stock Fund. The matched investments had to remain in the Stock Fund for two years, after which the employee could move the funds as he chose.
On September 18, 2002, EDS published an earnings warning, which precipitated a *304substantial drop in its stock price (from $36.46 to $17.20 a share). Although the stock price rebounded somewhat in the short term and more in the longer term, a flurry of lawsuits commenced.5
This case, while predicated on the same accounting and business irregularities as the securities actions, is brought on behalf of Participants in the Plan. (Participants may be members of the securities lawsuit class as well as the alleged Plan class.) The operative Class Complaint alleges three ERISA fiduciary violations relevant on appeal. In Count I, the Participants allege that the EDS Appellants6 breached their fiduciary duties of prudence when, despite knowledge of EDS’s financial problems, Appellants continued to offer company stock as a Plan investment option; directed and approved investment in the stock rather than in safer alternatives; invested matching funds in EDS stock; failed to take adequate steps to prevent the Plan from suffering losses from its EDS stock investment; and failed to implement a strategy to compensate for the high risk of EDS stock as a Plan investment. Count II alleges that Appellants breached their fiduciary duties by failing to monitor the Benefits Administration Committee and Investment Committee members who supervised the Plan and by failing to provide the committees with accurate information about company problems. Count IV7 alleges breach of their duties of loyalty to the Plan because the Appellants failed to act solely in the Participants’ interests and for the exclusive purpose of providing Plan benefits. All three Counts proceed under ERISA § 409 and § 502(a)(2) (29 U.S.C. § 1109(a) and § 1132(a)(2)). The crux of the allegations is the imprudence of company stock as a retirement offering.
Participants request reimbursement to “make good” the losses on behalf of the Plan, but they concede such damages must eventually be allocated among the Participants’ accounts. They also seek injunctive relief either to remove the EDS Stock Fund as an optional investment or to replace the current fiduciaries with one or more independent fiduciaries. The district court certified a Fed.R.Civ.P. 23(b)(2) class for these claims consisting of all Plan participants and their beneficiaries, excluding the Defendants, for whose accounts the Plan made or maintained investments in EDS stock through the EDS Stock Fund between September 7,1999, and October 9, 2002. As framed, the Class includes up to eighty-five thousand members.8
Appellants sought and were granted interlocutory review pursuant to Fed. R.Crv.P. 23(f).
A summary of the district court’s closely reasoned opinion regarding certification of *305these claims is essential to further analysis. Several of the court’s legal rulings underpin its conclusion that these claims are amenable to class certification. If the court erred in any of its threshold decisions, the class certification is put at risk.
First, the court rejected Appellants’ contention that Appellees’ claim should be characterized as individual claims for “other appropriate equitable relief’ to redress breaches of fiduciary duty under ERISA § 502(a)(3).9 See Varity Corp. v. Howe, 516 U.S. 489, 116 S.Ct. 1065, 134 L.Ed.2d 130 (1996). Instead, the court adopted the Participants’ contention that theirs is a “derivative” suit brought on behalf of the Plan pursuant to ERISA § 502(a)(2), in which recovery must “inure[ ] to the benefit of the plan as a whole,” Mass. Mut. Life Ins. Co. v. Russell, 473 U.S. 134, 140, 105 S.Ct. 3085, 3089, 87 L.Ed.2d 96 (1985).
Fastening on the derivative suit characterization, the court then ruled that ERISA § 404(c), which relieves fiduciaries of liability where loss results from a participant’s exercise of direction and control of his own account, is inapplicable to a suit on “behalf of the plan as a whole.” Finally, the court determined that post-employment releases of claims executed by up to nine thousand potential class members not only did not release claims for the Appellants’ breached fiduciary duties but in any event were irrelevant to the maintenance of a classwide claim for derivative relief to the Plan.
Turning to the class action rule, the court emphasized and discussed in tandem the typicality and adequacy factors,10 which bear on the qualification of class representatives. Because of its focus on the derivative nature of the claims, the court did not consider as stumbling blocks to adequacy and typicality two circumstances arguably at odds with the single-minded focus required of class representatives. First, one of the representatives, Mizell, was a day-trader in EDS stock who continued to buy and sell, to his occasional profit, throughout the tumultuous period following the September 19 price decline. Yet both Mizell and Smith, who also traded in EDS stock short-term, now contend, as putative class representatives, that Appellants should have withdrawn EDS stock as a permissible investment option for all Plan Participants during the class period. Second, the court discounted, also on its overarching derivative suit construct, the highly individual nature of class members’ stock trading patterns. In a securities fraud suit,11 class members seek recovery for specific transactions affected by fraud. Here, in contrast, the EDS Participants are joined as class members irrespective whether they bought or sold any EDS stock during the relevant period; irrespective whether they traded at a profit in shares that other Participants (fellow class members) sold for a loss simultaneously; and irrespective that some class cutoff dates would be vastly more profitable for some Participants than others. Further, thousands of class members remained in*306vested in EDS stock notwithstanding allegations that it was imprudent to offer or invest in EDS stock during the class period. The court held that because this is a derivative suit on the Plan’s behalf for losses “to the Plan as a whole,” the class representatives are not asserting claims for losses to individual accounts. Thus, the derivative characterization superseded conflicts among class members or between the class representatives and the class itself.
To the extent that the releases of claims might raise individual defenses, the court, while acknowledging this possibility, reiterated that a plan-wide lawsuit need not be defeated by the peculiarities of individual participants’ claims. Similarly, the court attempted to reconcile the ERISA § 404(c) defense with the derivative ERISA § 502(a)(2) action by concluding that (1) the defense is inapplicable to a fiduciary duty breach consisting of imprudent plan management and selection of investment options, and (2) the defense, being personal and transactional to a participant, cannot be applied where claims are made on behalf of the plan.
Having disposed of objections to the maintenance of a “derivative” suit for the Plan and to class action treatment, the court concluded that certification under Rules 23(b)(1) and (2) was appropriate.
Respecting Rule 23(b)(1), the court held that because the claims are asserted on behalf of the Plan as a whole the Appellants are “obligated to treat class members alike via their treatment of the Plan itself.” Further, the court foresaw a risk of inconsistent adjudication if multiple separate § 502(a)(2) cases were pursued against the Plan.
The court justified its Rule 23(b)(2) certification reasoning that (1) the complaint seeks “predominately” injunctive relief, i.e., removal of the EDS Stock Fund as an investment option and/or removal of the current fiduciaries, and (2) the monetary relief requested is a “group remedy” and “subservient” to the injunctive relief. In a footnote attached to this paragraph, the court acknowledged that a fiduciary would have to be appointed to oversee allocation of any monetary recovery among Plan Participants. Neither a Rule 23(b)(1) or (2) class action requires notice to class members or the option to opt-out.
II. DISCUSSION
This court reviews the district court’s certification decision for abuse of discretion. Gulf Oil Co. v. Bernard, 452 U.S. 89, 100, 101 S.Ct. 2193, 2200, 68 L.Ed.2d 693 (1981). The district court’s discretion must be exercised within the boundaries of Rule 23. Id. Where a district court rests its legal analysis on an erroneous understanding of governing law, it has abused its discretion. Unger v. Amedisys Inc., 401 F.3d 316, 320 (5th Cir.2005). Although federal courts cannot assess the merits of the case at the certification stage, they must evaluate with rigor “the claims, defenses, relevant facts and applicable substantive law in order to make a meaningful determination of the certification issues.” Id. at 321 (quoting Castano v. Am. Tobacco Co., 84 F.3d 734, 744 (5th Cir.1996)).
The party seeking class certification bears the burden of meeting all the Rule 23 requirements. Berger v. Compaq Computer Corp., 257 F.3d 475, 479-80 (5th Cir.2001). As was alluded to above, the requirements fall into two general groups: the four 23(a) requirements (numerosity, commonality, typicality, and representativeness), which must be met by all proposed class actions; and the three groups *307of Rule 23(b) requirements, one of which must be met by the proposed class.12
Courts should not confuse rulings on the merits of claims with the class certification decision. As noted above, however, the district court’s threshold legal rulings are essential to its conclusion that this case may be maintained as a class action. We must accordingly consider briefly whether (1) ERISA § 502(a)(2) entitled Plan Participants to seek derivative relief for “the plan as a whole” to recover “plan losses” that allegedly resulted from Appellants’ fiduciary duty breaches; and (2) whether either ERISA § 404(c) or the releases executed by about nine thousand Participants bar class certification.
A. Section 502(a)(2).
An ERISA fiduciary must act with prudence, loyalty and disinterestedness, requirements carefully delineated in the statute. See generally 29 U.S.C. § 1104(a)13. ERISA § 502(a)(2) authorizes any plan participant or beneficiary to sue on behalf of the plan to remedy a breach of these duties, to require the fiduciaries personally to “make good” any “losses to the plan” so caused, or to replace the fiduciaries.14 29 U.S.C. § 1132(a)(2); § 1109(a). Appellants strenuously contend that this suit, which alleges that Appellants breached fiduciary duties by failing to limit the Plan’s offering of and investment in EDS stock, cannot proceed under § 502(a)(2) because the Plan consists of individual Participant-directed investments. More precisely, Appellants contend that since any recovery of monetary damages would have to be allocated among up to eighty-five thousand class members based on each Participant’s widely divergent stock trading and holding strategy, no Plan-wide relief can be fashioned.
To the extent Appellants’ contention is that no plan-wide fiduciary duties exist with respect to 401(k) participant-directed plans, it is clearly overbroad. ERISA does not distinguish fiduciary duties according to the type of employee investment or pension plans at issue. The *308Supreme Court described Congress’s concern about “the possible misuse of plan assets, and with remedies that would protect the entire plan,” also without limitation concerning the type of plan. Russell, 473 U.S. at 142,105 S.Ct. at 3090. Certain fiduciary duty breaches can injure 401(k) participants generally and indiscriminately: theft from the plan; mapping;15 noncompliance with ERISA-mandated duties to inform; engaging in transactions that involve conflicts of interest; and setting unreasonable blackouts are among the possibilities.16 Allegations that ERISA fiduciaries promoted company stock to prop up its value or misled participants could also state plan-wide breaches of fiduciary duties.17
In this case, however, the description and indeed existence of a Plan-wide fiduciary breach are elusive at this preliminary stage of the case. The key contention is that the fiduciaries “knew” EDS stock was too risky to be offered or allowed as an investment by any Participant (or the vast bulk of them) in the 401(k) Plan during the period in question. This contention challenges the fiduciaries’ judgment that EDS was or remained a prudent investment for the Plan to offer.18 Hindsight is easy in a case like that of WorldCom, a company so infected by over-extension and fraud that it collapsed, and its stock became worthless. EDS, despite its alleged failings, is not in that category. From the facts adduced at the class determination stage, it is far from clear that EDS stock became too risky to be a permissible 401(k) offering or the basis for the employer-matching contribution. Thousands of Plan Participants continued to purchase EDS stock regularly after the company’s adverse disclosures and after the price dropped. Thousands held on to their EDS stock rather than sell. The stock price has slowly but steadily rebounded. Given these facts, plus the long-term horizon of retirement investing and the favored status Congress has granted to employee stock investments in their own companies, ascribing a Plan-wide fiduciary failure to Appellants seems fraught with uncertainty.19 Nevertheless, at this preliminary stage, we cannot rule out Appel-lees’ theories as a matter of law. Correla-tively, the possibility of a suit on behalf of *309the Plan as a whole is not eliminated simply by the fact that any recovery would have to be allocated among individual Participants’ 401(k) accounts.20
B. Section W(c) Defense.
While a brief look at the Participants’ theories confirms the district court’s conclusion that § 502(a)(2) claims could be brought on behalf of the Plan, the same cannot be said for the court’s rejection of § 404(c) as a defense to the derivative claims. Just as ERISA’s fiduciary duties may be breached on a plan-wide basis, so, too, must the § 404(c) defense be considered in its relation to the causes of action for recovery on behalf of a plan as a whole. Section 404(c) relieves a fiduciary from liability “for any loss” or “by reason of any breach” if the plan is an individual account plan and the loss “results from” a participant’s exercise of control over assets in his account.21 This provision places responsibility for the success or failure of a participant’s investments on his own choices among the portfolio offered in the plan. The defense does not apply to all plans, however. The Department of Labor is charged with defining the term “exercises control.” In its regulations, the Department implemented the Congressional purpose to qualify plans for this defense only if, inter alia, they offer a diversified array of investments; provide adequate information concerning the investments to the participants; and authorize flexible and autonomous control by the participants. See 29 C.F.R. § 2550.404e-l (2005). EDS’s Plan claims to fulfill the § 404(c) criteria for purposes of the allegations at issue in this appeal. Nevertheless, the district court held that “[a]s a separate entity, the Plan should not be subject to a defense that can only apply to particular participants and particular transactions.” We disagree with this conclusion.
Neither ERISA’s remedy provision, § 502(a)(2), nor § 404(c) articulates an exception to the availability of the § 404(c) defense when a plaintiff sues on behalf of a plan. It is the courts’ duty to harmonize *310statutory provisions, not, as the district court did, to eliminate one for the sake of crafting a more expansive remedy. In any event, the provisions do not conflict. The EDS 401(k) Plan is by definition the sum of the investment choices of its participants. If plan fiduciaries violate their duties, § 502(a)(2), as noted above, often affords a classwide remedy. Determining whether the fiduciary is relieved of liability because of § 404(c) is merely part of the statutory calculus.
A simple example will suffice to demonstrate how the provisions can work together. Suppose Plan fiduciaries neglected to credit 401 (k) plan accounts with stock dividends that had been received. A Participant could sue under § 502(a)(2) to recover the amount of the dividends and allocate them among accounts. The § 404(c) defense would play no role, because losses were unconnected to the Participant’s exercise of control over his individual account.
This case raises a more complex interpretive question whether the losses “result from” the participants’ exercise of control pursuant to § 404(c). The losses here could not have occurred but for two separate acts: the fiduciary’s inclusion of “bad” stocks into the pot, and the participants’ choices to invest in those “bad” stocks with full § 404(c) disclosure. When there are two actual causes of the loss, assuming the plan complies with § 404(c) regulations, how does a court determine whether the loss “results from” the participants’ exercise of control, which in turn determines whether the defense applies? Section 404(c) appears to leave the question open. Accordingly, the Department of Labor regulations come into play.
The Department has decided that § 404(c) may be a defense to liability when the loss is “the direct and necessary result of that participant’s or beneficiary’s exercise of control.” 29 C.F.R. § 2550.404c-l(d)(2)(i) (emphasis added). The DOL’s regulation gives the statutory term “result from” a narrow construction, but it is consistent with the statutory language — no liability when the losses “result from such participant’s or beneficiary’s exercise of control.” See 29 U.S.C. § 1104(c)(l)(A)(ii) (emphasis added).
An explanatory footnote to the regulation, however, narrows the statutory language even more in cases where the allegation is that the fiduciary was imprudent in its designation of investment options:
[T]he Department points out that the act of limiting or designating investment options which are intended to constitute all or part of the investment universe of an ERISA § 404(c) plan is a fiduciary function which, whether achieved through fiduciary designation or express plan language, is not a direct or necessary result of any participant’s direction of such plan.
Final Regulations Regarding Particular Directed Individual Account Plans (ERISA § 404(c) plans), 57 Fed.Reg. 46906, 46924-225, n. 27 (General Preamble, n. 27). The DOL as amicus, the dissent and the Appel-lees take this footnote to méan that when a plan loses money by reason of the fiduciary’s inclusion of an imprudent investment option, none of the loss is the direct and necessary result of the participant’s exercise of control. If the footnote is correct, it bars § 404(c) as a defense to EDS’s alleged breach in such cases.
Because application of the standard of judicial deference owed to the agency’s footnote is not determinative, we assume arguendo that the more demanding Chevron standard applies.22 The issue then *311becomes whether the DOL’s footnote reasonably interprets § 404(c) under Chevron Step II. We conclude it is not reasonable. Most important, the footnote does not reasonably interpret § 404(c) itself, because it contradicts the governing statutory language in cases where an individual account plan fully complies with the regulations’ disclosure, diversification and participant-control provisions, and loss is caused, notwithstanding some other fiduciary duty breach, by the participants’ investment decisions. The DOL footnote would render the § 404(c) defense applicable only where plan managers breached no fiduciary duty, and thus only where it is unnecessary. Similarly, the footnote is in tension with the actual DOL regulation, which does no more than narrowly construe ,§ 404(c) to authorize the defense for a fiduciary when a loss is a “direct and necessary result” of a participant’s exercise of control. See 29 C.F.R. § 2550.404e-l(d)(2)(i). The regulation also stresses that, “whether a participant ... has exercised independent control in fact with respect to a transaction depends on the facts and circumstances of the particular case.” 29 C.F.R. § 2550.404c-l(c)(2). The footnote is at odds with these provisions by appearing to eliminate a § 404(c) defense altogether, rather than determining its' scope on a transactional, case-by-case basis.
While various courts have deferred to the footnote with little or no discussion, the only circuit court to address § 404(c) found its meaning tolerably plain and explained that the provision “allows a fiduciary, who is shown to have committed a breach of duty in making an investment decision, to argue that despite the breach, it may not be held liable because the alleged loss resulted from a participant’s exercise of control.” In re Unisys Sav. Plan Litig., 74 F.3d 420, 445 (3rd Cir.1996). Unisys predated the DOL regulations but embodies a common sense interpretation of the statute.23
Disregarding the footnote and relying solely on the statute and the regulation does not, as the district court and Appel-lees fear, leave plan participants without a remedy for the type of fiduciary duty *312breaches alleged here. Instead, it correlates the potential recovery with the sum of participants’ decisions regarding their individual accounts. The Plan “as a whole” is not entitled to recover money damages for breach where an individual participant, suing on his own behalf, could not recover. The district court implicitly recognized this limitation in holding that with respect to the misrepresentation claims, which it did not certify for class treatment, § 404(c) affords an individual a transactionally oriented defense. Put otherwise, the § 404(c) defense is no different from a limitations defense in a class action. A classwide claim may be stated, but the potential recovery is limited to those class members whose claims have not prescribed. Moreover, § 404(c) in no way limits the recovery of equitable relief.
The dissent fears that if a § 404(c) defense applies, Plan participants and beneficiaries will be left “at the mercy of the wisdom of whoever made these limited [plan investment] choices.” The dissent is also concerned that no duty of prudence will attach to' the selection and monitoring of plan investment choices if § 404(c) is applied as written. These fears are both overblown and misdirected. Principally, we are not holding that a plan fiduciary’s duties do not include the selection and monitoring of plan investment alternatives. The question, rather, is how to harmonize the enforcement of the fiduciary’s duty with the § 404(c) defense when a § 502(a)(2) action is pursued “on behalf of the plan.” A plan fiduciary may have violated the duties of selection and monitoring of a plan investment, but § 404(c) recognizes that participants are not helpless victims of every error. Participants have access to information about the Plan’s investments, pursuant to DOL regulations, and they are furnished with risk-diversified investment options. In some situations, as happened here, many of the Participants will react to the company’s bad news by buying more of its stock. Other Participants will, like Mizell, trade their way to profit no matter the calamity that befell the stock. Section 404(e) contemplates an individual, transactional defense in these situations, which is another way of saying that in participant-directed plans, the plan sponsor cannot be a guarantor of outcomes for participants.
If the Appellees’ negation of § 404(c) prevails, then the EDS fiduciaries would be liable not just for losses in individual accounts, but also for failures to realize gains (measured against some entirely speculative standard) and even for catchup amounts where participants bought into a declining EDS stock value.
The harmonization of § 502(a)(2) actions with the § 404(c) defense, however, limits the amount of “plan losses” for which a fiduciary may be held liable. This harmonization also bears on the susceptibility of this case to class action treatment, because § 404(c) individualizes the consequences of fiduciary duty violations. Finally, there is no inconsistency between this harmonization and the courts’ decisions in the Enron and WorldCom cases, because in those cases, where the company’s stock value ultimately rested on a financial house of cards, no trading strategy in the company’s stock could have salvaged a participants’ company stock ownership.24
*313Because the district court incorrectly eliminated the § 404(c) defense from its evaluation of the suitability of the allegations on appeal for class treatment, we must vacate and remand for further consideration of the extent to which § 404(c) decisions by participants undermine the feasibility of class action treatment.
C. Participant Releases.
While conceding that ordinarily the fact that up to nine thousand potential class members have signed releases of claims against EDS would defeat typicality and preclude class certification, the district court found a distinction here for two reasons. First, the court determined that the releases (which are otherwise quite broad, discharging “all claims or demands” against EDS) authorize the instant suit as one for “benefits.”25 Appellants contend, with some force, that this exception only permits suits under ERISA § 502(a)(1)(B) to recover specific benefits owed a participant under the terms of an employee plan. .As the Supreme Court explained in Russell, ERISA § 502(a)(1)(B) allows a beneficiary to recover plan “benefits,” whereas § 502(a)(2) allows recovery that inures to the benefit of the plan as a remedy for breach of fiduciary duties. Russell, 473 U.S. at 146-47, 105 S.Ct. at 3093; see also Rhorer v. Raytheon Eng’rs & Constructors, Inc., 181 F.3d 634, 639 (5th Cir.1999) (noting the numerous differences between causes of action under §§ 502(a)(1)(B) and 502(a)(2)). On the other hand, a release does not ordinarily preclude claims based on subsequent conduct. The enforceability of the releases presents difficult questions.
Additionally, the district court refused to consider individual releases pertinent to the maintenance of a derivative suit on behalf of the Plan. For the reasons stated in regard to the § 404(c) defense, however, this conclusion is untenable. The impact of the releases should not have been excluded from the district court’s certification analysis.
Without commenting further on the enforceability of the releases or application of the “benefits” exception, we note that holders of releases could become a subclass if a class action is otherwise deemed appropriate. Contrary to the dissent, we are not holding that the releases foreclose any § 502(a)(2) suit on behalf of the Plan or foreclose any class certification. We do stress, however, that the status of perhaps nine thousand claimants is not a trifle- — - either to the Appellants or the claimants themselves. The district court must consider the releases more thoroughly on remand.26
D. Class Action Issues.
Applying the § 404(c) defense and factoring in the nine thousand releases may well change the district court’s decision to *314certify a class action. Nevertheless, we must also address the two Rule 23(a) class certification issues challenged directly by Appellants — typicality of the representative Plaintiffs’ claims and adequacy of their representation' — as well as the court’s ultimate authorization of a Rule 23(b)(1) and (2) no-notice, no-opt-out class action. We conclude that Smith and Mizell hold sufficiently typical claims, but the court must reconsider whether they are adequate representatives in light of inherent intraclass conflicts. Finally, various difficulties demonstrate the impropriety of maintaining a Rule 23(b)(2) class action and the court’s superficial analysis of the Rule 23(b)(1) alternative.
1. Typicality.
Rule 23(a) requires that the named representatives’ claims be typical of those of the class. Appellants question whether Smith’s and Mizell’s claims are typical because Mizell continued to invest in EDS stock even after it declined following the September 18th disclosures, and Smith actually made money on his EDS investments (although not as much as he thinks he should have). The district court ruled these inquiries inappropriate since the representatives’ derivative claims on behalf of the Plan transcend individual claim variations. On the contrary, the requirements of Rule 23(a) cannot be waved away by artful characterization. Even if the typicality requirement did not apply, Smith and Mizell would have the burden to prove, as derivative representatives of the Plan, that their claims fairly represent those of the absent Participants.
Stated broadly, the representatives’ claims are typical of those of the class. Smith and Mizell both allege that they suffered harm as Participants who lost money on EDS stock investments through the Appellants’ imprudent Plan management. The fact that Mizell continued to trade in EDS stock after the company’s adverse disclosures may signify an intraclass conflict of interest and may cut against his attempt to avert a § 404(e) defense, but it does not disable him from being a typical class representative. This court recently noted that “the key typicality inquiry is whether a class representative would be required to devote considerable time to rebut Defendants’ claims.” Feder, 429 F.3d at 138 (quoting Lehocky v. Tidel Techs., 220 F.R.D. 491, 501-02 (S.D.Tex.2004)). Feder went on to join numerous decisions which have held that securities class action plaintiffs are not categorically precluded from asserting typical claims despite them own post-disclosure trading in the target defendant’s stock. Id. Such trading becomes harmless where, after the company has made adverse disclosures, the stock price reverts to valuation based on an efficient market. The analogy between securities fraud and ERISA fiduciary violation plaintiffs is inexact, as Appellants point out, in the face of Mizell’s contentions that even after the September 18th disclosures, EDS stock remained an imprudent Plan investment. A trading strategy adopted for Mizell’s personal benefit is, however, distinguishable from the Plan fiduciaries’ execution of their duties. Similar reasoning vindicates Smith’s claim to typicality, reducing Appellants’ complaint over his profit to questions of damages and the § 404(c) defense.
2. Adequacy.
In addition to measuring the competence of class counsel and the class representatives’ willingness and ability to serve, neither of which criteria are challenged here, the Rule 23 adequacy inquiry also uncovers “‘conflicts of interest between the named plaintiffs and the class they seek to represent.’ ” Berger v. Com*315paq Computer Corp., 257 F.3d 475, 479-80 (5th Cir.2001) (quoting Amchem Prods., Inc. v. Windsor, 521 U.S. 591, 625, 117 S.Ct. 2231, 2236, 138 L.Ed.2d 689 (1997)).
Substantial conflicts exist among the class members, raising questions about the adequacy of the lead Plaintiffs’ ability to represent the class. Even after the EDS earnings warning and the drop in its stock price, thousands of Plan Participants (would-be class members), including Mi-zell, continued to direct money into the EDS Stock Fund. Over forty-four thousand Participants maintained investments in EDS stock as of February, 2004. This aggregate conduct seriously undermines the claim that the EDS Stock Fund was an imprudent investment that Appellants should not have offered in the first place. The intraclass conflict is exacerbated because Appellants seek injunctive relief that would dissolve the EDS Stock Fund;27 the Fund cannot be partially shut down for the litigating Plaintiffs and remain open for absent class members who desire this investment option.
Additionally, Plan Participants were affected by the drop in price in dramatically different ways. Class discovery revealed that Smith and sixteen thousand absent class members made money on their stock fund investments, while others, including Mizell, lost money. Further conflicts exist among those who lost money. According to David Ross’s report, for 17,890 class members, maximum recovery would inure to the Plan (and eventually be allocated to their accounts) if February 4, 2000, is established as the date on which the stock fund became an imprudent investment. For 37,689 class members, maximum recovery would be attained if November 27, 2001, were the designated date. Appellees dismiss these concerns by asserting that all Plan Participants share the goal of attaining maximum payment to the Plan, regardless of the designated date. This is true as a general matter and surely promotes the interest of the class representatives and their counsel. Appellees gloss over the inconvenient fact that these conflicts have implications not only for dividing the pie at recovery but also for discovery and preparation for trial. Unlike a securities fraud lawsuit, in which class members have a uniform purpose in proving material misrepresentations by company defendants at specific points in time, here the goal is to second-guess judgments made by the Appellants involving a multitude of considerations over a period of years. The facts, once known, may bear out different legitimate theories as to when EDS Stock Fund became an imprudent investment; each theory will have different consequences for class members’ recovery.
Numerous courts have held that intraclass conflicts may negate adequacy under Rule 23(a)(4). See Valley Drug Co. v. Geneva Pharmaceuticals, Inc., 350 F.3d 1181, 1189-92 (11th Cir.2003) (finding class representatives inadequate where their economic interests and objectives conflicted substantially with those of absent class members); Pickett v. Iowa Beef Processors, 209 F.3d 1276, 1280 (11th Cir.2000)(representation inadequate where class includes those “who claim harm from the very acts from which other class members benefitted”).
The trial court too readily succumbed to Appellees’ minimization of the intraclass *316problems in this case.28 That the court recognized a fiduciary would need to be appointed to allocate recovery among Plan Participants concedes at least the possibility of intraclass apportionment problems. The problem goes to the heart of proving the allegations of fiduciary imprudence. On remand, the district court must more fully consider the implications of the proven intraclass conflicts for the adequacy of representation by Smith and Mizell. If a class is certified, the court may have to consider certifying subclasses to represent the participants with conflicting interests.
3. The Allison Rule 23(b) (2) Inquiry.
With little difficulty, the district court concluded that because Plaintiffs’ derivative lawsuit was filed on behalf of the Plan and sought “predominately” equitable remedies, it should be certified as a class pursuant to Rule 23(b)(2). The court did not afford absent class members the option of notice or self-exclusion from the class. Certification of a class under Rule 23(b)(2) is appropriate where “the party opposing the class has acted or refused to act on grounds generally applicable to the class, thereby making appropriate final injunc-tive relief or corresponding declaratory relief with respect to the class as a whole.” Fed.R.Civ.P. 23(b)(2). The district court cited this court’s decision in Allison v. Citgo Petroleum Corp., 151 F.3d 402 (5th Cir.1998), which held that “monetary relief predominates in (b)(2) class actions unless it is incidental to requested injunctive or declaratory relief.” Id. at 415. This Allison (b)(2) predominance requirement, “by focusing on uniform relief flowing from defendants’ liability, ‘serves essentially the same functions as the procedural safeguards and efficiency and manageability standards mandated in (b)(3) class actions.’ ” In re Monumental Life Ins. Co., 365 F.3d 408, 417 (5th Cir.2004) (quoting Allison, 151 F.3d at 414-15).29
Allison also imposed standards for determining whether monetary relief sought in a Rule 23(b)(2) class action is truly incidental, or whether such relief is the true pursuit of the class action:
Ideally, incidental damages should be only those to which class members automatically would be entitled once liability to the class (or subclass) as a whole is established. That is, the recovery of incidental damages should typically be concomitant with, not merely consequential to, class-wide injunctive or declaratory relief. Moreover, such damages should at least be capable of computation by means of objective standards and not dependent in any significant way on the intangible, subjective differences of each class member’s circumstances. Liability for incidental damages should not require additional hearings to resolve *317the disparate merits of each individual’s case; it should neither introduce new and substantial legal or factual issues, nor entail complex individualized determinations.
Allison, 151 F.Sd at 415 (internal citations omitted). Allison’s test has been cited in connection with other ERISA class action determinations. See Nelson v. IPALCO Enters. Inc., No. 1P02-477CHK, 2003 WL 23101792 (S.D.Ind. Sept. 30, 2003) (unpublished).
Two considerations persuade us that the district court got it backwards. This court has refused to permit certification of a class where many members “have nothing to gain from an injunction, and the declaratory relief they seek serves only to facilitate the award of damages.” Bolin v. Sears, Roebuck & Co., 231 F.3d 970, 978 (5th Cir.2000). As just noted, many potential class members have voted with their investments to remain in the EDS Stock Fund and, inferably, do not want it closed; other potential class members profited from stock swings caused by the alleged fiduciary violations; and still other potential class members would gain or lose damages based on the breach date selected by the court. In light of these real, not simply alleged, problems caused by such conflicts, the inability of absent class members to receive notice of this suit or have an opportunity to opt out is extremely troubling.
Second, to effectuate Appellees’ principal goal—reimbursement into the individual accounts of each Plan Participant—numerous individualized hearings would be required. Final resolution of class members’ claims will involve “new and substantial legal and factual issues,” Allison, 151 F.3d at 415, including the § 404(c) defense, whether an individual class member was actually harmed by the purported breaches of fiduciary duty, and the releases. Resolution of these claims will require “complex individualized determinations,” Allison, 151 F.3d at 415. Again, the district court’s acknowledgment that a fiduciary would have to sort out the claims of individual class members demonstrates how little the “incidental damages” (which would total many millions of dollars) will “be more in the nature of a group remedy,” as Allison intended. See id.
The inappropriateness of Rule 23(b)(2) in this ease is strongly supported by the court’s decision in Nelson, which states:
Relief will depend on individualized calculations for each account. As noted, individual claimants may present issues of causation and reliance, so that a class-wide determination that defendants violated ERISA’s requirements would not necessarily lead to an award in favor of a particular claimant. Also, defendants may be able to raise individual defenses regarding each class member. Thus, monetary relief here would not “flow directly from liability to the class as a whole.” Certification under Rule 23(b)(2) is not available here.
Id. at *11.
It may be objected that because Plaintiffs’ suit is characterized as a derivative action on behalf of the Plan, resort to the Rule 23 class action requirements is not mandated, and Rule 23(b)(2) best represents a compromise between the derivative nature of the claims and the ultimate relief that may be granted in individual Participants’ accounts. Lower court cases are in fact divided over which provision of Rule 23 applies. Compare Piazza v. EBSCO Indus., Inc., 273 F.3d 1341, 1352-53 (11th Cir.2001) (abuse of discretion for the district court to certify a(b)(3) class) with Coan v. Kaufman, 349 F.Supp.2d 271 (D.Conn.2004)(“... Courts ... have nonetheless applied the procedural safeguards of either Rule 23 or Rule 23.1 in order to *318protect the plan and absent participants.”) (citing cases). Perhaps no general procedural rule can be enunciated. In this case, we are confident that the subtlety of the fiduciary claims alleged, the intraclass conflicts and the individualized nature of potential defenses mandated that the case proceed as a class action and equally mandated, on the facts before us, against the propriety of a Rule 23(b)(2) class. On remand, after further consideration, the court may adduce sufficient grounds to approve a class pursuant to the standards this court has developed.
I. Rule 23(b)(1).
The district court also purported to certify a class under Rule 23(b)(1). Although certification must be reversed under Rule 23(a), we point out the court’s cursory Rule 23(b)(1) analysis in the interest of judicial efficiency and to provide guidance on remand. See United States v. Murillo-Lopez, 444 F.3d 337, 339 & n. 5 (5th Cir.2006).
Numerous courts, like the district court, have conclusionally declared that a(b)(l) class is appropriate in an ERISA lawsuit “on behalf of the plan.” Of course, a Rule 23(b)(1)(B) limited fund class action is plainly not appropriate. See Ortiz v. Fibreboard Corp., 527 U.S. 815, 119 S.Ct. 2295, 144 L.Ed.2d 715 (1999). What the court evidently meant was a certification under Rule 23(b)(1)(A), which authorizes a class action where the party opposing the class would be subject to “incompatible standards” if separate actions were brought. Such a remedy has some intuitive appeal to the extent that Plaintiffs here seek equitable relief: A judgment removing the fiduciaries in one lawsuit would be inconsistent with a judgment in another permitting them to stay. On the other hand, as even the dissent recognizes, achieving injunctive relief is not the principal goal of this litigation.30 The focus on monetary damages would set this case apart from the examples of classic Rule 23(b)(1) class actions, which are based on situations “in which different results in separate actions would impair the opposing party’s ability to pursue a uniform course of conduct.” C.Wright, A.MilleR, & M.KANE, 7A FEDERAL PRACTICE & PROCEdure § 1773, at 16 (2005 ed.).
If the district court eventually reaches a Rule 23(b) analysis, it should consider the extent to which the due process concerns inherent in Allison apply to a (b)(1)(A) class and whether a (b)(1)(A) class can be maintained if damages are the primary remedy sought. See Zinser v. Accufix Research Inst., Inc., 253 F.3d 1180, 1193-95 (9th Cir.2001). The resolution of these issues is still uncertain in the Fifth Circuit. What seems fairly clear is that depriving tens of thousands of EDS shareholders of notice and opt-out protections, where there are undeniable intraclass conflicts pertinent to significant monetary outcomes, would create an unacceptable risk of unfair treatment of class members.31
III. CONCLUSION
For the foregoing reasons, the class certification by the district court is VACAT*319ED and REMANDED. The court may reconsider its class certification pursuant to the standards discussed herein.
VACATED AND REMANDED.
. The Plaintiffs-Appellees include both participants in the EDS Plan and their beneficiaries. They are referenced collectively as Participants in our discussion. The named Plaintiffs include Jeffrey Clay Smith and Richard Mizell.
. More American employees now participate in defined contribution plans such as 401(k) plans than in defined benefit plans. U.S. Department of Labor, Bureau of Labor Statistics, Employee Participation in Defined Benefit and Defined Contribution Plans, 1985-2000, http://www.bls.gov/opub/cwc/cm 20030325tb01.htm (last visited Apr. 27, 2006).
. Whether or to what extent the EDS Stock Fund qualified as an employee stock ownership plan or an eligible individual account plan exempt from certain fiduciary duties pursuant to, for example, 29 U.S.C. §§ 1104(a)(2), 1107(b), is not at issue in this appeal.
. As its name implies, the EDS Stock Fund could invest up to ninety-nine percent of its assets in company stock.
. This court recently upheld Rule 23(b)(3) class certification in a consolidated securities fraud suit brought against EDS concerning the same events and alleging that the Defendants' actions concealed accounting problems and improperly inflated the value of EDS stock. Feder v. Elec. Data Sys. Corp., 429 F.3d 125 (5th Cir.2005).
. The Defendants-Appellants include, inter alia, EDS executives charged with monitoring the committees running the Plan, as well as members of the Benefits Administration Committee and the Investment Committee.
. Count III, another fiduciary duty claim based on misrepresentation under ERISA § 502(a)(3) (29 U.S.C. § 1132(a)(3)), was not certified as a class action by the district court, after it concluded that this claim rested on disparate individual fact issues. The Plaintiffs have not cross-appealed this ruling.
. Appellants' expert David Ross calculated about . eighty-five thousand class members through the Appellees’ original class cutoff date of February 24, 2004. Since the class as certified cuts off in October, 2002, the actual number is probably lower.
. The court did, however, conclude that the claims for misrepresentation by the fiduciaries were more properly brought under § 502(a)(3) because of the reliance element.
. In order to merit class action treatment, the allegations of a complaint must initially demonstrate numerosity, commonality of issues, typicality of the class representatives' claims among those of the class, and the adequacy of the representatives and their counsel. See Fed.R.Civ.P. 23(a); Feder, 429 F.3d at 129. Neither numerosity nor commonality is at issue here, as the district court noted.
. It is undisputed that the Plan Participants who bought or sold EDS stock are members of the class certified in Feder, supra.
. E.g., Stirman v. Exxon Corp., 280 F.3d 554, 558-59 (5th Cir.2002).
. These duties under the statute include, "the care, skill, prudence, and diligence under the circumstances then prevailing that a prudent man acting in a like capacity and familiar with such matters would use in the conduct of an enterprise of a like character and with like aims.” Id. § 1104(a)(1)(B). The DOL's regulation under § 404(a)(1)(B) says that a fiduciary must "give[] appropriate consideration to those facts and circumstances that, given the scope of such fiduciary's investment duties, the fiduciary knows or should know are relevant to the particular investment or investment course of action involved ...” and must act accordingly. 29 C.F.R. § 2550.404a-l(b)(l)(i)-(ii). Appropriate consideration includes "[a] determination by the fiduciary that the particular investment or investment course of action is reasonably designed, as part of the portfolio, ... to further the purposes of the plan, taking into consideration the risk of loss and the opportunity for gain (or other return) associated with the investment or investment course of action.” Id. § 2550.404a-l(b)(2)(i). For a non-§ 404(c) plan, the fiduciary’s selecting an investment (as provided in § 404(a)(1)(B)) is not only like a fiduciary's selecting an investment option, but also like a participant's investing in an option under § 404(c).
.In this "comprehensive and reticulated statute,” Nachman Corp. v. Pension Benefit Guar. Corp., 446 U.S. 359, 361, 100 S.Ct. 1723, 1726, 64 L.Ed.2d 354 (1980), ERISA § 502 (29 U.S.C. § 1132) authorizes two other types of remedial actions. Section 502(a)(1) enables beneficiaries to sue for plan “benefits.” Section 502(a)(2), as noted above, provides for suits against fiduciaries on behalf of the plan. Section 502(a)(3) is a "catchall” provision entitling a beneficiary to "other appropriate equitable relief” for fiduciary duty breaches. See Great-West Life & Annuity Ins. Co. v. Knudson, 534 U.S. 204, 221 & n. 5, 122 S.Ct. 708, 718, 151 L.Ed.2d 635 (2002).
. When employee funds are transferred from one plan to another, some companies use a process called “mapping.” With "mapping," each of the displaced investment options is compared to the new options. During conversion, amounts are automatically transferred or “mapped” from the displaced option to the most comparable new option. See Wiseman v. First Citizens Bank & Trust Co., 212 F.R.D. 482, 484 (W.D.N.C.2003).
. This opinion does not concern, and we do not opine on the subjects covered in the recent opinion, Milofsky v. American Airlines, 418 F.3d 429 (5th Cir.2005), vacated en banc, 442 F.3d 311 (5th Cir.2006).
. To the extent allegations of nondisclosure were made against Appellants in this case, the district court ruled that individual reliance issues precluded certification of a § 502(a)(2) class.
. Under ERISA, the prudence of investments or classes of investments offered by a plan must be judged individually. See In re Unisys Sav. Plan Litig., 74 F.3d 420, 438-41 (3d Cir.1996).
. The Third Circuit wisely balanced the competing policies of ERISA fiduciary duties with statutory exemptions to those duties crafted by Congress to encourage employees’ investments in their companies' stocks. See Moench v. Robertson, 62 F.3d 553, 568-73 (3d Cir.1995). The Moench standard was adopted by the Sixth Circuit, see Kuper v. Iovenko, 66 F.3d 1447, 1458-59 (6th Cir.1995), and favorably commented on by the Ninth Circuit, Wright v. Oregon Metallurgical Corp., 360 F.3d 1090, 1097-98 (9th Cir.2004).
. We note that Participants would not be eligible to pursue relief under § 502(a)(3) for "other equitable relief' under Great-West because the damages they seek do not restore to them specific funds that were inequitably kept in the Defendants’ possession. At best, their action would seem to be one for legal restitution, which is not cognizable under § 502(a)(3). See Great-West, 534 U.S. at 214, 122 S.Ct. at 714-15.
. ERISA § 404(c), 29 U.S.C. § 1104(c), entitled "Control over assets by participant or beneficiary,” reads in full:
(1) In the case of a pension plan which provides for individual accounts and permits a participant or beneficiary to exercise control over the assets in his account, if a participant or beneficiary exercises control over the assets in his account (as determined under regulations of the Secretary)
(A)such participant or beneficiary shall not be deemed to be a fiduciary by reason of such exercise, and
(B)no person who is otherwise a fiduciary shall be liable under this part for any loss, or by reason of any breach, which results from such participant’s or beneficiary’s exercise of control.
(2) In the case of a simple retirement account established pursuant to a qualified salary reduction arrangement under section 408(p) of Title 26, a participant or beneficiary shall, for purposes of paragraph (1), be treated as exercising control over the assets in the account upon the earliest of—
(A) an affirmative election among investment options with respect to the initial investment of any contribution,
(B) a rollover to any other simple retirement account or individual retirement plan, or
(C) one year after the simple retirement account is established.
No reports, other than those required under section 1021(g) of this title, shall be required with respect to a simple retirement account established pursuant to such a qualified salary reduction arrangement.
. There is much disagreement over whether the DOL's footnote is entitled to Chevron def*311erence. It can be asserted that the footnote itself was subject to notice and comment rule-making and therefore is subject to the Chevron steps. The “Final Regulation Regarding Participant Directed Individual Account Plans” includes the footnote, even though it is not in the actual "Code of Federal Regulations.” 57 F.R. 46906-01. This is because the CFR never publishes the preambles of the Final Regulations, even though the preambles were part of the notice and comment process. The final rule in its entirety, including the preamble, is published only in the Federal Register. For an explanation of what portions of regulations are published in certain books, see www.llsdc.org/sourcebook/fed-reg-cfr.htm. In this case, footnote 27 was included in the original notice, see 52 F.R. 33508, and received comments before final passage.
Nevertheless, the footnote constitutes at best a comment on the regulations, and is not itself a regulation. Thus, an alternative argument can be made that neither Chevron nor Auer deference is owed. See Auer v. Robbins, 519 U.S. 452, 461, 117 S.Ct. 905, 911, 137 L.Ed.2d 79 (1997); Chevron USA, Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837, 842-43, 104 S.Ct. 2778, 2781-82, 81 L.Ed.2d 694 (1984). The dissent asserts that the footnote represents an "interpretation” of the DOL regulation, to which Chevron deference is due. What the dissent overlooks, however, is that this rule only applies if the regulation was ambiguous. See Wells Fargo Bank of Texas v. James, 321 F.3d 488, 494 (5th Cir.2003); Christensen v. Harris County, 529 U.S. 576, 585, 120 S.Ct. 1655, 1663, 146 L.Ed.2d 621 (2000). Neither the dissent nor any of the authorities it cites points to an ambiguity in the regulation.
. See also, Wiseman, supra, where the court noted that individual assessments of § 404(c) defenses were required where, despite plan managers’ alleged fiduciary duty breach, some participants had made deliberate decisions to hold onto declining stocks.
. Finally, contrary to the dissent, while we "agree that § 404(c) provides no shield” for the two-year retention of matching contributions in EDS stock, that match cannot be the subject of any ERISA fiduciary duty violation if the requirement embodied a settlor decision, not a decision subject to the fiduciaries’ discretion. The issue has not been briefed before us, the district court did not decide it, and we do not speculate on its resolution.
. The pertinent language in the releases states:
This Release does not include, however, a release of Employee’s right, if any, to benefits he/she is entitled to under any EDS plan qualified under Section 401(a) of the Internal Revenue Code, including the EDS Retirement Plan and the EDS 401(k) Plan, and COBRA benefits pursuant to Internal Revenue Code section 4980B.
. Even if, as the dissent suggests, the effect of the releases may be considered on a class-wide basis, the named Plaintiffs may not be adequate representatives of those class members who did sign them. See Jayne E. Zan-glein & Susan J. Stabile, Erisa Litigation 479-80 (2d ed. 2005)(''[C]ourts have regularly found standing, typicality, or adequacy lacking where the defense of a release of claims was not shared by the named plaintiffs and the purported class .... [I]f none of the named plaintiffs signed releases, they are inadequate representatives because none of them would have any need to litigate or interest in litigating the release issue.”)
. More pointedly, even if Appellees prevail without receiving an injunction, their assertion that the mere existence of the EDS Stock Fund violated a fiduciary duty under ERISA will have won the day. It is hard to imagine that the Fund would continue to exist after such a finding.
. Indeed, intraclass problems can present problems of constitutional magnitude. See Hansberry v. Lee, 311 U.S. 32, 43-44, 61 S.Ct. 115, 119-120, 85 L.Ed. 22 (1940). The dissent's suggestion that although "some members may not want EDS stock removed as an investment alternative [this] does not present a conflict” is not far from saying that the fact that the Hansberry family did not want to enforce the covenant barring blacks from living in their neighborhood does not present a class conflict with those who sought, through a class action judgment, to enforce the covenant against them. A few class members cannot hijack litigation "on behalf of the plan” to pursue their preference at the expense of others who are not given notice of this purported representation. The interests of all class members must be fundamentally consistent.
. “Allison reflects our concern that Plaintiffs may attempt to shoehorn damage actions into the Rule 23(b)(2) framework, depriving class members of notice and opt-out protections.” Bolin v. Sears, Roebuck & Co., 231 F.3d 970, 976 (5th Cir.2000).
. The dissent contends that no intraclass conflict exists with respect to the class members' competing views on injunctive relief since the propriety of injunctive relief will be determined at the end of litigation and an injunction may be unnecessary.
. The Eleventh Circuit decision in Piazza v. Ebsco Indus., Inc., 273 F.3d 1341 (11th Cir.2001), certified a Rule 23(b)(1)(A) class action to redress fiduciary duty breaches to an ERISA plan pursuant to § 502(a)(2), but no intraclass conflicts were asserted against the maintenance of the class or as a basis for questioning the denial of notice and opt-out.
