OPINION OF THE COURT
SCIRICA, Chief Judge.
At issue in this antitrust action are the standards a district court applies when deciding whether to certify a class. We will vacate the order certifying the class in this case and remand for proceedings consistent with this opinion.
I.
Purchasers of hydrogen peroxide and related chemical products brought this antitrust conspiracy action against chemical manufacturers.1 An inorganic liquid, hydrogen peroxide is used most prominently as a bleach in the pulp and
paper industry with smaller amounts appearing in chemicals and laundry products, environmental applications, textiles, and electronics. Hydrogen peroxide is available in solutions of different concentrations and grades depending on its intended use. Major concentrations are 35, 50, and 70 percent. The grades, roughly in order from least- to most-expensive, are: standard, food/cosmetic (which must meet FDA standards), electronic, and propulsion. All defendants sold the standard grade, but not all defendants sold all other grades. Defendants sold different amounts of each of the grades. Each grade has different supply and demand conditions because the grades are sold to end-users in a variety of industries with different economic characteristics. According to defendants, the different grades are not economic substitutes for each other, but plaintiffs disagree. Prices diverge dramatically among grades; electronic or propulsion grade can be as much as five times more expensive than standard grade.
The other two products at issue are sodium percarbonate and sodium perborate, together known as persalts, which are granular solids containing hydrogen peroxide used primarily as detergents. Among the defendants, only Solvay produced and sold sodium percarbonate in the United States during the class period. Solvay Chemicals, Degussa Corp., and FMC sold sodium perborate in the United States during the class period. Akzo, Arkema, and Kemira did not sell or produce sodium perborate in the United States during the class period.
After the United States Department of Justice and the European Commission began investigating possible violations of the antitrust laws in the hydrogen peroxide industry,2 several
plaintiffs filed class action complaints against producers of hydrogen peroxide and persalts under § 4 of the Clayton Act,
The District Court denied defendants’ motion to dismiss the complaint for failure to state a claim. Following extensive discovery,3 plaintiffs moved to certify a class of direct purchasers of hydrogen peroxide, sodium perborate, and sodium percarbonate, over an eleven-year class period. In support of class certification, plaintiffs offered the opinion of an economist. Defendants, opposing class certification, offered the opinion of a different economist. Defendants separately moved to exclude the opinion of plaintiffs’ economist as unreliable under Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993).
Concluding plaintiffs’ expert‘s opinion was admissible and supported plaintiffs’ motion for class certification, the District Court certified a class of direct purchasers of hydrogen peroxide, sodium perborate, and sodium percarbonate under
All persons or entities, including state, local and municipal government entities (but excluding defendants, their parents, predecessors, successors, subsidiaries, and affiliates as well as
federal government entities) who purchased hydrogen peroxide, sodium perborate, or sodium percarbonate in the United States, its territories, or possessions, or from a facility located in the United States, its territories, or possessions, directly from any of the defendants, or from any of their parents, predecessors, successors, subsidiaries, or affiliates, at any time during the period from September 14, 1994 to January 5, 2005.
We granted defendants’ petition for an interlocutory appeal under
II.
Class certification is proper only “if the trial court is satisfied, after a rigorous analysis, that the prerequisites” of Rule 23 are met.5 Gen. Tel. Co. of Sw. v. Falcon, 457 U.S. 147, 161 (1982); see Beck v. Maximus, Inc., 457 F.3d 291, 297 (3d Cir. 2006); see also Amchem Prods., Inc. v. Windsor, 521 U.S. 591, 615 (1997) (Rule 23(b)(3) requirements demand a “close look“). “A class certification decision requires a thorough examination of the factual and legal allegations.” Newton, 259 F.3d at 166.6
Class certification under Rule 23 has two primary components. The party seeking class certification must first establish the four requirements of Rule 23(a): “(1) the class is so numerous that joinder of all members is impracticable [numerosity]; (2) there are questions of law or fact common to the class [commonality]; (3) the claims or defenses of the representative parties are typical of the claims or defenses of the class [typicality]; and (4) the representative parties will fairly and adequately protect the interests of the class [adequacy].”
The trial court, well-positioned to decide which facts and legal arguments are most important to each Rule 23 requirement, possesses broad discretion to control proceedings and frame issues for consideration under Rule 23. See Amchem, 521 U.S. at 630 (Breyer, J., concurring in part and dissenting in part) (recognizing that the decision on class certification may implicate “highly fact-based, complex, and difficult matters“). But proper discretion does not soften the rule: a class may not be certified without a finding that each Rule 23 requirement is met. Careful application of Rule 23 accords with the pivotal status of class certification in large-scale litigation, because denying or granting class certification is often the defining moment in class actions (for it may sound the “death knell” of the litigation on the part of plaintiffs, or create unwarranted pressure
III.
Here, the District Court found the Rule 23(a) requirements were met, a determination defendants do not now challenge. Plaintiffs sought certification under Rule 23(b)(3), which is permissible when the court “finds that the questions of law or fact common to class members predominate over any questions affecting only individual members, and that a class action is superior to other available methods for fairly and efficiently adjudicating the controversy.”7
Only the predominance requirement is disputed in this appeal. Predominance “tests whether proposed classes are sufficiently cohesive to warrant adjudication by representation,” Amchem, 521 U.S. at 623, a standard “far more demanding” than the commonality requirement of Rule 23(a), id. at 623–24, “requiring more than a common claim,” Newton, 259 F.3d at 187. “Issues common to the class must predominate over individual issues . . . .” In re The Prudential Ins. Co. of Am. Sales Practices Litig., 148 F.3d 283, 313–14 (3d Cir. 1998). Because the “nature of the evidence that will suffice to resolve a question determines whether the question is common or individual,” Blades v. Monsanto Co., 400 F.3d 562, 566 (8th Cir. 2005), “‘a district court must formulate some prediction as to how specific issues will play out in order to determine whether common or individual issues predominate in a given case,‘” In re New Motor Vehicles Can. Exp. Antitrust Litig., 522 F.3d 6, 20 (1st Cir. 2008) [hereinafter New Motor Vehicles] (quoting Waste Mgmt. Holdings, Inc. v. Mowbray, 208 F.3d 288, 298 (1st Cir. 2000)).8 “If proof of the essential elements of the cause of action requires individual treatment, then class certification is unsuitable.” Newton, 259 F.3d at 172. Accordingly, we examine the elements of plaintiffs’ claim “through the prism” of Rule 23 to determine whether the District Court properly certified the class. Id. at 181.
A.
The elements of plaintiffs’ claim are (1) a violation of the antitrust laws—here, § 1 of the Sherman Act, (2) individual injury resulting from that violation, and (3) measurable damages.
Importantly, individual injury (also known as antitrust impact) is an element of the cause of action; to prevail on the merits, every class member must prove at least some antitrust impact resulting from the alleged violation. Bogosian v. Gulf Oil Corp., 561 F.2d 434, 454 (3d Cir. 1977); see Newton, 259 F.3d at 188 (In antitrust and securities fraud class actions, “[p]roof of injury (whether or not an injury occurred at all) must be distinguished from calculation of damages (which determines the actual value of the injury)“).
In antitrust cases, impact often is critically important for the purpose of evaluating Rule 23(b)(3)‘s predominance requirement because it is an element of the claim that may call for individual, as opposed to common, proof. See New Motor Vehicles, 522 F.3d at 20 (“In antitrust class actions, common issues do not predominate if the fact of antitrust violation and the fact of antitrust impact cannot be established through common proof.“); Bell Atl. Corp. v. AT&T Corp., 339 F.3d 294, 302 (5th Cir. 2003) (“[W]here fact of damage cannot be established for every class member through proof common to the class, the need to establish antitrust liability for individual class members defeats Rule 23(b)(3) predominance.“); see also Blades, 400 F.3d at 572 (“[P]roof of conspiracy is not proof of common injury.“).
Plaintiffs’ burden at the class certification stage is not to prove the element of antitrust impact, although in order to prevail on the merits each class member must do so. Instead, the task for plaintiffs at class certification is to demonstrate that the
Here, the District Court found the predominance requirement was met because plaintiffs would be able to use common, as opposed to individualized, evidence to prove antitrust impact at trial. On appeal, defendants contend the District Court erred in three principal respects in finding plaintiffs satisfied the predominance requirement: (1) by applying too lenient a standard of proof for class certification, (2) by failing meaningfully to consider the views of defendants’ expert while crediting plaintiffs’ expert, and (3) by erroneously applying presumption of antitrust impact under Bogosian, 561 F.2d at 454–55.
We review a class certification order for abuse of discretion, which occurs if the district court‘s decision “rests upon a clearly erroneous finding of fact, an errant conclusion of law or an improper application of law to fact.” Newton, 259
B.
We summarize briefly the evidence and arguments offered to the District Court. As noted, both plaintiffs and defendants presented the opinions of expert economists. Importantly, the experts disagreed on the key disputed predominance issue—whether antitrust impact was capable of proof at trial through evidence common to the class, as opposed to individualized evidence.
Plaintiffs’ expert, John C. Beyer, Ph.D., offered an opinion purporting to show that “there is common proof that can
Beyer also observed a “pricing structure” in the hydrogen peroxide industry which, he contended, showed prices across producers, grades and concentrations of hydrogen peroxide, and
My analysis of the similarity in price movements over time indicates that hydrogen peroxide prices charged by different manufacturers are affected by the same market forces of supply and demand . . . . These similarities in movement are sometimes referred to as “pricing structure” or “structure to prices.” This analysis confirms that prices would have behaved similarly, in a consistent and generalized manner[,] to a conspiracy to fix prices at artificially high levels [and] to restrict output or to allocate customers.
Beyer also pointed to coordinated increases in list prices by defendants as evidence of common impact.
Beyer identified two “potential approaches” to estimating damages on a class-wide basis: (1) benchmark analysis, which would compare actual prices during the alleged conspiracy with prices that existed before the class period; and (2) regression analysis, through which it “may be possible . . . to estimate the relationship between price of hydrogen peroxide, sodium perborate, and sodium percarbonate and the various market forces that influence prices, including demand and supply
Defendants offered the opinion of their own expert economist, Janusz A. Ordover, Ph.D., to “provide an independent expert assessment of whether certification of the proposed class of Plaintiffs is appropriate in this matter.” Specifically, Ordover set out to address “whether, assuming a conspiracy of the kind described in the Complaint, the Plaintiffs will be able to show, through common proof, that all or virtually all of the members of the proposed class suffered economic injury caused by the alleged conspiracy.” Ordover also “opine[d] on whether a formulaic approach exists by which impact could be demonstrated and damages to the class could be reasonably calculated.” Ordover responded to and disputed many of Beyer‘s opinions.
First, Ordover disputed Beyer‘s finding that hydrogen peroxide and persalts are fungible, contending that the “various grades of hydrogen peroxide . . . [and persalts] have different supply characteristics and face different demand conditions. The existence of supply and demand characteristics that are specific to the various grades and uses requires individualized assessment of the impact of the alleged conspiracy at least across these different grades and uses. Consequently, a finding of class-wide impact from the alleged conspiracy cannot be inferred from the mere fact of the conspiracy and from common
Ordover also found some of defendants’ price-increase announcements were ineffective—actual prices did not follow the purported announcements—suggesting list prices could not be used to measure antitrust impact on a basis common to the class. Ordover observed that a number of contracts for the sale of hydrogen peroxide were individually negotiated, with a variety of contract terms. And deposition testimony from named plaintiffs indicated list prices were sometimes disregarded. Ordover opined that the statistical methods by which Beyer proposed to demonstrate common impact and damages were not feasible. Given the record of prices and output in the industry and the apparent influence of individualized factors on pricing, “class-wide assessment of impact based on aggregate price information [was] impossible,” and any formulaic approach to determine a set of “but-for prices” would have to incorporate a multitude of different “variables,” defeating any reasonable notion of proof common to the class.
Significantly, Ordover presented empirical analysis of the data on individual sales transactions and found that different customers purchasing the two most common grades and three most common concentrations from the same hydrogen peroxide producer in a given year were as likely to experience a decline in actual prices over the year as an increase, while other similarly situated customers experienced no change in price. Defendants contend this disparity goes to the core of the predominance issue—plaintiffs and their expert, Beyer, failed to “explain . . . how or which common proof could be used to determine that the alleged conspiracy impacted customers whose prices declined, as well as customers whose prices increased or stayed the same, over the same time period.”12 Br. of Appellant at 5. Beyer, according to defendants, only “promised” to come up with a method to overcome this obstacle, without showing or even suggesting how it might be done. Defendants contend the market analysis is “generic” and note it would apply equally to a large number of industries. With respect to the pricing structure analysis, they contend Beyer‘s use of average prices, rather than those of individual transactions, to show pricing structure, was erroneous because it glossed over differences in actual prices. The theme of defendants’ argument is that the
In addition to presenting Ordover‘s testimony, defendants moved to exclude Beyer‘s testimony as unreliable, citing Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579 (1993).13 The District Court denied the Daubert motion in its memorandum and order certifying the class.

The District Court concluded the predominance requirement was met. It held that “[e]ither [Beyer‘s] market

A.
Defendants contend the District Court applied too lenient a standard of proof with respect to the Rule 23 requirements by (1) accepting only a “threshold showing” by plaintiffs rather than making its own determination, (2) requiring only that plaintiffs demonstrate their “intention” to prove impact on a class-wide basis, and (3) singling out antitrust actions as appropriate for class treatment even when compliance with Rule 23 is “in doubt.”
Although it is clear that the party seeking certification must convince the district court that the requirements of Rule 23 are met, little guidance is available on the subject of the proper standard of “proof” for class certification.14 The Supreme Court has described the inquiry as a “rigorous analysis,” Falcon, 457 U.S. at 161, and a “close look,” Amchem, 521 U.S. at 615, but
1.
The following principles guide a district court‘s class certification analysis. First, the requirements set out in Rule 23 are not mere pleading rules. Szabo, 249 F.3d at 675-77. The court may “‘delve beyond the pleadings to determine whether the requirements for class certification are satisfied.‘” Newton, 259 F.3d at 167 (quoting 5 James Wm. Moore et al., Moore‘s Federal Practice § 23.61[5]); see Beck, 457 F.3d at 297 (same); see also Johnston v. HBO Film Mgmt., Inc., 265 F.3d 178, 189 (3d Cir. 2001) (district court properly “examine[d] the factual record underlying plaintiffs’ allegations in making its certification decision“).15
The evidence and arguments a district court considers in the class certification decision call for rigorous analysis. A party‘s assurance to the court that it intends or plans to meet the requirements is insufficient. See id. at 191 (“[W]here the court finds, on the basis of substantial evidence as here, that there are serious problems now appearing, it should not certify the class merely on the assurance of counsel that some solution will be found.” (quoting Windham v. Am. Brands, Inc., 565 F.2d 59, 70 (4th Cir. 1977)) (quotation marks omitted); Wachtel v. Guardian Life Ins. Co., 453 F.3d 179, 184, 186 (3d Cir. 2006) (the requirement that a district court include in its class certification order “a clear and complete summary of those claims, issues, or
Support for our analysis is drawn from amendments to Rule 23 that took effect in 2003. First, amended
Fed. R. Civ. P. 23 directs that certification decisions be made “at an early practicable time.”Fed. R. Civ. P. 23(c)(1)(a) . This recent amendment replaced the language of the old rule: The former “‘as soon as practicable’ exaction neither reflect[ed] prevailing practice nor capture[ed] the many valid reasons that may justify deferring the initial certification decision.” SeeFed.

See [Newton, 259 F.3d at 166] (“[I]t may be necessary for the Court to probe behind the pleadings before coming to rest on the certification question.“) (quoting [Falcon, 457 U.S. at 160]) . . . .
Id. at 347-48 n.17; see Gariety, 368 F.3d at 365 (noting the change).20 Relatedly, in introducing the concept of a “trial
As the Standing Committee on Rules of Practice and Procedure explained in its report proposing this amendment, the new language authorizes the more flexible approach many courts take to class-action litigation, recognizing the important consequences to the parties of the court‘s decision on certification. The current rule‘s emphasis on dispatch in making the certification decision has, in some circumstances, led courts to believe that they are overly constrained in the period before certification. A certain amount of discovery may be appropriate during this period to illuminate issues bearing on certification, including the nature of the issues that will be tried; whether the evidence on the merits is common to the members of the proposed class; whether the issues are susceptible to class-wide proof; and what trial-management problems the case will present.
Report of the Judicial Conference Committee on Rules of Practice and Procedure to the Chief Justice of the United States and Members of the Judicial Conference of the United States 10 (2002) [hereinafter Committee Report].
A critical need is to determine how the case will be tried. An increasing number of courts require a party requesting class certification to present a “trial plan” that describes the issues likely to be presented at trial and tests whether they are susceptible of class-wide proof.
Additionally, the 2003 amendments eliminated the language that had appeared in Rule 23(c)(1) providing that a class certification “may be conditional.”21 The Advisory Committee‘s note explains: “A court that is not satisfied that the requirements of Rule 23 have been met should refuse certification until they have been met.” The Standing Committee on Rules of Practice and Procedure advised:
The provision for conditional class certification is deleted to avoid the unintended suggestion, which some courts have adopted, that class certification may be granted on a tentative basis, even if it is unclear that the rule requirements are satisfied.
Committee Report, supra, at 12; see 5 Moore‘s Federal Practice
While these amendments do not alter the substantive standards for class certification, they guide the trial court in its proper task—to consider carefully all relevant evidence and make a definitive determination that the requirements of Rule 23 have been met before certifying a class. See IPO, 471 F.3d at 39 (2003 amendments “arguably combine to permit a more extensive inquiry into whether Rule 23 requirements are met than was previously appropriate“); Oscar, 487 F.3d at 267 (noting that these “subtle changes” reflect that “a district court‘s certification order often bestows upon plaintiffs extraordinary leverage, and its bite should dictate the process that precedes it“).
To summarize: because each requirement of Rule 23 must be met, a district court errs as a matter of law when it fails to resolve a genuine legal or factual dispute relevant to determining the requirements.
2.
Class certification requires a finding that each of the requirements of Rule 23 has been met.22 See Unger, 401 F.3d
In reviewing a district court‘s judgment on class certification, we apply the abuse of discretion standard. A district court abuses its discretion in deciding whether to certify a class action if its “decision rests upon a clearly erroneous finding of fact, an errant conclusion of law or an improper application of law to fact.” In re Gen. Motors Corp. Pick-Up Truck Fuel Tank Prods. Liab. Litig., 55 F.3d 768, 783 (3d Cir. 1995) (citation and quotation marks omitted); see Newton, 259 F.3d at 165. Under these Rule 23 standards, a district court
If a class is certified, “the text of the order or an incorporated opinion must include (1) a readily discernible, clear, and precise statement of the parameters defining the class or classes to be certified, and (2) a readily discernible, clear, and complete list of the claims, issues or defenses to be treated on a class basis.” Wachtel, 453 F.3d at 187; see
B.
Although the District Court properly described the class certification decision as requiring “rigorous analysis,” some statements in its opinion depart from the standards we have articulated. The District Court stated, “So long as plaintiffs demonstrate their intention to prove a significant portion of their case through factual evidence and legal arguments common to all class members, that will now suffice. It will not do here to make judgments about whether plaintiffs have adduced enough evidence or whether their evidence is more or less credible than defendants‘.” With respect to predominance, the District Court
Citing Cumberland Farms, Inc. v. Browning-Ferris Industries, 120 F.R.D. 642, 645 (E.D. Pa. 1988), the District Court reasoned, “[i]t is well recognized that private enforcement of [antitrust] laws is a necessary supplement to government action. With that in mind, in an alleged horizontal price-fixing conspiracy case when a court is in doubt as to whether or not to
To the extent that the District Court’s analysis reflects application of incorrect standards, remand is appropriate. We recognize that the able District Court did not have the benefit of the standards we have articulated. Faced with complex, fact-intensive disputes, trial courts have expended considerable effort to interpret and apply faithfully the requirements of
Defendants contend the District Court erred as a matter of law in failing to consider the expert testimony of defendants’ expert, Ordover, instead deferring to the opinion of plaintiffs’ expert, Beyer. Plaintiffs do not dispute that a district court may properly consider expert opinion with respect to
In addressing defendants’ Daubert motion to exclude Beyer‘s opinion, the court discussed whether it should consider Ordover‘s opinion in deciding whether Beyer‘s opinion was admissible. The court stated it would be improper to “weigh the relative credibility of the parties’ experts“—in other words, to weigh Ordover‘s opinion against Beyer‘s—for the purpose of deciding whether to admit or exclude Beyer‘s opinion. Concluding Beyer‘s opinion was admissible, the court denied the Daubert motion. But in addressing the
Expert opinion with respect to class certification, like any matter relevant to a
Resolving expert disputes in order to determine whether a class certification requirement has been met is always a task for the court—no matter whether a dispute might appear to implicate the “credibility” of one or more experts, a matter resembling those usually reserved for a trier of fact. Rigorous analysis need not be hampered by a concern for avoiding
That weighing expert opinions is proper does not make it necessary in every case or unlimited in scope. As the Court of Appeals for the Second Circuit instructed,
To avoid the risk that a
Rule 23 hearing will extend into a protracted mini-trial of substantial portions of the underlying litigation, a district judge must be accorded considerable discretion to limit both discovery and the extent of the hearing onRule 23 requirements. But even with some limits on discovery and the extent of the hearing, the district judge must receive enough evidence, by affidavits, documents, or testimony, to be satisfied that eachRule 23 requirement has been met.
IPO, 471 F.3d at 41. In its sound discretion, a district court may find it unnecessary to consider certain expert opinion with respect to a certification requirement, but it may not decline to resolve a genuine legal or factual dispute because of concern for an overlap with the merits. Genuine disputes with respect to the
2.
Plaintiffs contend the District Court‘s acceptance of their expert‘s opinion was consistent with In re Linerboard Antitrust Litigation, 305 F.3d 145 (3d Cir. 2002), an antitrust conspiracy action in which we affirmed class certification. There are a number of surface similarities between this case and Linerboard. Plaintiffs’ expert, Beyer, also appeared as an expert for the plaintiffs in Linerboard, and in both cases he presented an analysis of the industry and a “structure in pricing” analysis. Id. at 153. As in Linerboard, Beyer here proposed to demonstrate antitrust impact through the use of “benchmarks” and “multiple regression analysis.” Id. at 153–54. In affirming the district court‘s grant of class certification in Linerboard, we concluded that Beyer, along with another expert for the plaintiffs, “effectively utilized supporting data, including charts and exhibits, to authenticate their professional opinions that all class members would incur” antitrust impact. Id. at 155.
We do not question plaintiffs’ general proposition, which the District Court accepted, that a conspiracy to maintain prices could, in theory, impact the entire class despite a decrease in prices for some customers in parts of the class period, and despite some divergence in the prices different plaintiffs paid. But the question at class certification stage is whether, if such impact is plausible in theory, it is also susceptible to proof at trial through available evidence common to the class. When the latter issue is genuinely disputed, the district court must resolve it after considering all relevant evidence. Here, the District Court apparently believed it was barred from resolving disputes between the plaintiffs’ and defendants’ experts.
D.
Defendants contend the District Court, by relying on Bogosian v. Gulf Oil Corp., 561 F.2d 434 (3d Cir. 1977), erroneously presumed the predominance requirement was met. In Bogosian, also a Clayton Act § 4 case in which plaintiffs sought class certification, the district court had denied class certification on the assumption that the issue of antitrust impact would have to be proven on an individual, as opposed to common, basis. Id. at 454. Finding that assumption erroneous, we reasoned that “when an antitrust violation impacts upon a class of persons who do have standing, there is no reason in doctrine why proof of the impact cannot be made on a common basis so long as the common proof adequately demonstrates some damage to each individual. Whether or not fact of damage can be proven on a common basis therefore depends upon the circumstances of each case.” Id. Applying the concept, we continued:
If, in this case, a nationwide conspiracy is proven, the result of which was to increase prices to a class of plaintiffs beyond the prices which would
obtain in a competitive regime, an individual plaintiff could prove fact of damage simply by proving that the free market prices would be lower than the prices paid and that he made some purchases at the higher price. If the price structure in the industry is such that nationwide the conspiratorially affected prices at the wholesale level fluctuated within a range which, though different in different regions, was higher in all regions than the range which would have existed in all regions under competitive conditions, it would be clear that all members of the class suffered some damage, notwithstanding that there would be variations among all dealers as to the extent of their damage.
Id. at 455; see Newton, 259 F.3d at 179 n.21 (“In antitrust class actions, injury may be presumed when it is clear the violation results in harm to the entire class.“); Linerboard, 305 F.3d at 151–53.
In Linerboard, we found a “strong argument [could] be made that the Bogosian concept of presumed impact was properly applied” on the facts of that case. Id. at 152. Plaintiffs had alleged a horizontal conspiracy by manufacturers to restrict supply and raise prices of linerboard, the paper lining used in corrugated cardboard boxes and sheets. Id. Over a two-year period, defendants allegedly had agreed to idle their plants to reduce inventories to a twenty-year low and boost prices. Id. at
While the District Court found the Bogosian presumption applied, it also relied on Beyer‘s analysis. Cf. Linerboard, 305 F.3d at 155 (“[T]his was not a case where plaintiffs relied solely on presumed impact and damages.“). As in Linerboard, plaintiffs here stress that they do not rely merely on Bogosian‘s presumption to support class certification, but also on their
The District Court, upon review of all the evidence consistent with this opinion, may again consider whether the reasoning in Bogosian is compatible with the record of this case.

Rule 12(b)(6) is that a motion to dismiss tests the legal sufficiency of a pleading. Its factual sufficiency will be tested later—by a motion forsummary judgment under Rule 56 , and if necessary by trial. By contrast, an order certifying a class usually is the district judge‘s last word on the subject; there is no later test of the decision‘s factual premises (and, if the case is settled, there could not be such an examination even if the district judge viewed the certification as provisional).
Time may be needed to gather information necessary to make the certification decision. Although an evaluation of the probable outcome on the merits is not properly part of the certification decision, discovery in aid of the certification decision often includes information required to identify the nature of the issues that actually will be presented at trial. In this sense it is appropriate to conduct controlled discovery into the “merits,” limited to those aspects relevant to making the certification decision on an informed basis. Active judicial supervision may be required to achieve the most effective balance that expedites an informed certification determination without forcing an artificial and ultimately wasteful division between “certification discovery” and “merits discovery.”
