INTRODUCTION This matter is before the Court on the motion of the direct purchaser plaintiffs for class certification under Rule 23(b)(3) of the Federal Rules of Civil Procedure. Also before the Court is the motion of the defendants to exclude what they refer to as "interline-related cornmunications" from consideration for class certification or for any other purpose under 49 U.S.C. § 10706. The Court heard oral argument on both motions on October 6 and 7, 2010, and took them under advisement. The Court delayed decision on the motions until after the Supreme Court decided Wal-Mart Stores, lnc. v. Dukes, 131 S. Ct. 2541 (2011), and then invited the parties to file supplemental briefs discussing the impact of the Wal~i\/Iart decision on the class certification question in this case. Those briefs have been filed, and the motions now are ripe. Upon consideration of the parties’ papers, the oral arguments presented by counsel, the relevant legal authorities, and the entire extensive record in this case, the Court finds by a preponderance of the evidence that the direct purchaser plaintiffs have satisfied all of the requirements of Rule 23. 'I`he Court therefore will grant the direct purchaser plaintiffs’ motion for class cer“tification; will certify this case as a class action under Rule 23(1:))(3) for purposes of litigation and trial; will define the class as proposed by the direct purchaser plaintiffs in their motion for class certification; will certify for class treatment the direct purchaser plaintifi"s’ claim for price fixing in violation of Section 1 of the Sherman Act, 15 U.S.C. § l; will designate the eight named plaintiffs as the class representatives; and will appoint Quinn Emanuel Urquhart & Sullivan, LLP and Hausfled LLP as co-lead class counsel. The Court concludes that it need not rule at this time on the defendants’ motion to exclude interline-related communications.‘ ’ The papers reviewed in connection with the pending motions include the following: Class Cerlij?catfort. The second consolidated amended class action coinplaint ("Zd Arn. Compl.") [Dkt. No. 324]; the direct purchaser plaintiffs’ motion for class certification ("Class Mot.") [l)kt.

Co., 602 F.3d 444, 445~46, 454 (D.C. Cir. 2010). lt therefore will limit its discussion accordingly This case involves the claim that defendants - BNSF Railway Cornpany ("BNSF"); CSX 'l`ransportation, lnc. ("CSX"); Norfolk Southern Railway Company ("NS"); and certification or any other purpose prohibited by 49 U.S.C. § 10706 ("Iiiterline Mem.") {Dl 2011 WL 5603995, at *1 (D.D.C_ Nov. 17, 2011) (Facciola, l\/lag. J.). Magistrate judge Facciola’s expertise in e-discovery matters and his weekly conference calls with counsel during the early stages of discovery made possible an efficient and largely non~contentious discovery process despite the complexity of the case and the challenging nature of some of the discovery issues. Complaint, and all federal governmental entities, and (b) all entities or persons that paid a Fuel Surcharge directly to any of the Defendants solely pursuant to a railroad-shipper contract that was (i) entered into before July l, 2003, and (ii) provided for a stand-alone Fuel Surcharge to be paid under a predetermined formula specifically set forth in the contract. Class l\/lot. at l. Plaintiffs request that this case be certified as a class action for litigation and trial of plaintiffs’ claim for price fixing under Section 1 of the Sherman Act, 15 U.S.C. § l, and that the eight named plaintiffs _ Dust Pro, lnc.; Carter Distributing Company; Dakota Granite Company; Donneliy Commodities, lnc.; U.S. Magnesium LLC; Nyrstar Taylor Chemicals, lnc.; Olin Corporation; and Strates Shows, lnc. m be designated as class representatives Class Mot. at l. Plaintiffs further request that Quinn Emanuel Urquhart & Sullivan, LLP and Hausfeld LLP be designated as co-lead class counsel under Rule 23(g) of the Federal Rules of Civil Procedure. Defendants oppose plaintiffs’ motion for class certification, arguing that plaintiffs have failed to satisfy the requirements of Rule 23. A. The Alleged Cons',r)fracy Plaintiffs allege that in early 2003 defendants, the four largest Class l railroads in the continental United States, § 2d Am. Compl. ‘ll 1, conspired to increase their total revenues through the use of standardized, uniforin, and supra~coriipetitive fuel surcharges. Rail Freight l, 587 F. Supp. 2d at 29. A Class l railroad is a large freight railway company that has "annual carrier operating revenues of at least $250 inillion." lst Rausser Report at 20. Together, defendants coinprise just one percent of all the freight railroads, § id., but control about 90 percent of rail freight traffic in the United States. 2d Am. Compl. 114; § Class Mein. at 7'. BNSF and UP operate in the western United States; CSX and NS operate in the east. S_e_e lst Rausser Report at 30-31; Willig Report 11 166.3 Before Congress passed the Staggers Rail Act in 1980, defendants would have had to apply to the interstate Commerce Commission ("ICC") for approval of an across-the-board rate increase. Rail Freight l, 587' F. Supp. 2d at 29~30. Following the deregulation of the railroad industry, at least 80 percent of all rail shipments now move under private transportation contracts, which are not rate regulated, or are otherwise exempt from rate regulation. I_d. Plaintiffs allege that defendants ultimately determined that the most efficient way to increase their profits was through the imposition of an across-the-board, artificially high, and uniform fuel surcharge, g Q. at 30, instead of attempting to renegotiate all of their individual contracts, §§., or attempting to fix each base rate separately, which plaintiffs say "would have been extremely complex, highly costly and effectively unmanageable." lst Rausser Report at 52 n.l 18. The total freight price for a shipping customer, that is, the all-in rate, consists of a base rate (also referred to as a line~haul rate) and any percentage fuel surcharge applied to the base rate. _S_e§ Willig Report1l iS; Class Opp. at 3 (all-in price includes the base rate, fuel surcharge, and other charges and elements of value). The base rate 3 To preview, §§ g at 61 n.ll & 64 n.12, Gordon Rausser is plaintiffs’ retained expert, and Robert D. Willig is defendants’ retained expert. Dr. Rausser is the Robert Gordon Sproul Distinguislied Professor at the University of California at Berkeley. He has held positions teaching economics and statistics at numerous universities and has published widely in these fields g lst Rausser Report at l. Dr. Willig is a Professor of Econoinics and Public Affairs at Princeton University, where he holds a joint appointment in the Economics Department and at the Woodrow Wilson School of Public and international Affairs. His focus is rnicroeconoinics, specializing in industrial organization He has published widely in these fields §“eme_ Willig Report at 1. includes fixed cost (or overhead) elements, such as the cost of organizing a particular shipment[,] . . . . the large fixed costs of building and maintaining track, bridges, and other structures to achieve long-run sustainability[,] . . . . [and] the railroad’s markup of price over costs, i.e., the profitability element of pricing. lst Rausser Report at 62. Plaintiffs allege that defendants imposed "an across-the-board artificially high and uniform fuel surcharge" as a percentage multiplier of the base rate, thereby permitting defendants "to raise total freight prices widely by a given percentage." , 587 F. Supp. 2d at 30; g ali lst Rausser Report at 50 ("[A]dding a percentage fuel surcharge on top of line-haul rates or base rates is by its very nature a general price increase."). ln effect, according to plaintiffs, the allegedly conspiratorial fuel surcharges operated like a tax, increasing the total price of shipping by a set percentage. lst Rausser Report at 80. Plaintiffs contend that this "approach yielded defendants billions of dollars of additional profits because the surcharge raised rates far beyond the real increased cost of fuel." Rail Freight l, 587 F. Supp. 2d at 30. According to plaintiffs, it took defendants some trial and error to reach the point of conspiracy. Before the class period, plaintiffs say that defendants "operated as a price-discriminating, interdependent, but non-collusive oligopoly." Class Mem. at 8. And for many years before the class period, defendants "confronted a long-term, structural decline in rail freight rates." § "Between 2000 and early 2003, the three-year period preceding the Class Period," plaintiffs contend that defendants "unilaterally took various actions designed to increase rail freight prices and revenues." _Ig. at 9. As plaintiffs describe it, "[t]hese uncoordinated actions included, among other things, unilateral attempts to apply stand-alone fuel surcharges, which were designed ‘to take advantage of future rising fuel prices’ and intended as ‘revenue enhancement steps."’ Q. (quoting RD Ex. 9, E-inail from C. Adains, at UPFSC 0}47060, Dec. 5, 2002; RD Ex. 163, NS 2000 Annual Report, at 3). But plaintiffs contend that defendants "acting on their own had li1nited success when trying to boost revenues through fuel surcharges." Q. Plaintiffs contend that these pre-class period "fuel surcharges were applied only sporadically to a limited number of shippers," because defendants were concerned about competition -e "losing business to other [railroads] that did not apply fuel surcharges[.]" lc_l. at 9-10. Another barrier to broad application of fuel surcharges during the pre-class period, according to plaintiffs, was wide use of "the so-called Rail Cost Adjustmeiit Factor, or ‘RCAF."’ Class Mem. at l l. The RCAF "is a weighted index that accounts for all significant input costs, including fuel." Q.; me_e g_l_gg Willig Rep. jj 63 ("RCAF measures changes in the prices of major components of the railroad industry’s operating expenses, including labor, fuel, materials, equipment rents, depreciation, interest and other expenses.”). According to plaintiffs, wide use of the RCAF impeded broad application of fuel surcharges because defendants "recognized that imposing a stand-alone fuel surcharge where fuel price increases were already covered by the RCAF would be perceived by shippers as double dipping.” Class Mern. at ll (quotations omitted). Thus, plaintiffs contend that before the class period the number of shippers covered by stand~alone, rate-based fuel surcharges was relatively low . . . , and fuel surcharges did not contribute significantly to Defendants’ revenues or bottom lines, Defendants were unable to meet their respective revenue enhancement goals through the use of uncoordinated fuel surcharges. Class l\/lem. at 12. 10 But all of this allegedly changed in 2003. Plaintiffs contend that beginning in the spring of 2003 "[t]lie four Defendants agreed to create and apply a common Fuel Surcharge" -»»~ linked to the price of oil on one of two oil indexes, the On-Highway Diesel Fuel ("HDF") index or the West Texas intermediate ("Wl`l") index - "based on a percentage of base rates on an across-the-board basis to all members of" plaintiffs’ putative class. Class Mem. at l9. Under CSX's new, allegedly conspiratorial fuel surcharge program, the railroad would assess a 0.4 percent surcharge when the price of oil on the WTI index exceeded $23 per barrel, and an additional 0.4 percent for every dollar above $23. § at 19. Plaintiffs say that "{u]nlike its predecessor program, which required the price of oil to exceed the threshold price ($28 per barrel under the old program) for 30 consecutive days, CSX’s new program would be based on the average price of oil from the preceding nionth." E. at 19-20. And plaintiffs allege that BNSF, UP, and NS adopted "essentially unifonn" programs, and all four defendants "remained in synch through the class period." § at 24. As plaintiffs describe it, "[t]he only differences in the Defendants’ programs concerned the indices used and the thresholds chosen. The two indices chosen were closely related. The western railroads (BNSF and the UP) linked their fuel surcharge to the on-highway diesel fuel (HDF) index, whereas the eastern railroads (CSX and NS) linked their fuel surcharge to the [W"l`l] index." Class Mem. at 24 n.76 (quoting 1stRausser Report at 54-55). Although UP and BNSF used slightly different thresholds in their fuel surcharge programs, plaintiffs allege that this difference "had no practical effect”: "The UP applied a fuel surcharge when the HDF was above the threshold of $135 per gallon and the BNSF applied a Fuel ll Surcharge when the HDF index was above $l .25 per gallon. CSX and NS both applied fuel surcharges when the WTI index was above $23 per barrel. The different thresholds used by UP and BNSF were not relevant to fuel surcharge amounts during the class period, because the indices were all above the threshold values for the entire Class Period. Consequently, the UP and BNSF Fuel Sureharge programs provided for identical fuel surcharge percentages once the $i .35 threshold was reached." _l_c_l. (quoting lst Rausser Report at 55). The next step in the alleged conspiracy, according to plaintiffs, was defendants’ agreement and collective action to cause the American Association of Railroads ("AAR") to create a new cost escalation index, the All Inclusive index Less Fuei ("AIILF"), that removed fuei costs from the prior cost escalation index, the All inclusive index ("AII"), on which the RCAF was based. §§e_ Rail Freight I, 587 F. Supp. 2d at 30; _s_e_e Class Mern. at 27. Piaintiffs say that defendants reached this agreement during the October and Dece1nber 2003 meetings of the AAR; the AIILF index was published in December 2003. Rail Freight I, 587 F. Supp. 2d at 30; §e_e Class Mem. at 29. As plaintiffs describe it, "[t]he magnitude of this accomplishment from Defendants’ perspective cannot be understated." Class Men’i. at 29. Plaintiffs point to a letter written by BNSF’s chief economist, Sam Kyei, in which he stated: "ln December 2003 [Matt Rose, BNSF’s chief executive officer], single~handedly got the A.A.R. to establish a non-fuel RCAF index, now called the All-inclusive index Less Fuei . . . . In my IS-year railroad career, no one had ever succeeded in steering the A.A.R. to do this. . . . [T]he combination of sound price escalation using this index and a fuel surcharge should tremendously help our bottom-line for years to come. In fact, . . . the entire rail industry should benefit from the escalation options the index provides." Class Mein. at 29-30 (quoting RD Ex. 122, Letter from S. Kyei, at BNSF-0070502, Mar. l5, 2005). l2 At this p‘>int, plaintiffs allege that defendants, having coordinated their fuel surcharges and created and published the AII`LF, "worked tirelessly to achieve 100% Fuel Surcharge coverage across their customers." Class l\/lem. at 31. Plaintiffs say that following defendants’ agreement to coordinate their fuel surcharges, defendants’ fuel surcharge revenue "skyrocketed": as an example, plaintiffs state that NS saw fuel surcharge revenue for certain businesses grow exponentially from about $l l.6 million in 2002 to about $61.7 million, $208 miliion, $650 inillion, and $9”!4 million in 2003, 2004, 2005, and 2006, respectively _I_c_i. at 42-43. Plaintiffs say that because of the conspiracy, defendants "were able to reverse the long-term downward trend in rail freight rates and move rates sharply upward[,]" Q. at 43, at the expense of putative class inembers. l_d. at 45. B. Surface Transpor‘iation Board Proceedfir.gs and 18 Class Acrz`on Lawsuits Eventually, shippers of both rate-regulated and rate-unregulated freight traffic complained about defendants’ use of fuel surcharges, arguing that the surcharges recovered far more than the incremental cost of fuei, and that the surcharges had become non-negotiable Shippers of rate-regulated traffic expressed their cornplaints to the Surface Transportation Board ("STB"), § 2d Am. Compl. 11 96; Class Mem. at 47, an agency that regulates certain aspects of the railroad industry § Manufacturers Ry. Co. v. Surface Transp. Bd., 676 F.3d 1094, 1095 (D.C. Cir. 2012). in response, the STB "instituted [a] proceeding to inquire into rail carrier practices related to fuel surcharges." Rail Fuel Surcharges, Ex Parte No. 661, 2007 WL 201205, at *l (S.T.B. Jan. 26, 2007). 13 As the STB made clear, its proceedings on fuel surcharges and its ultimate decision on the matter related only to rate-regulated freight traffic. §ee Rail Fuel Surcharges, 2007 WL 201205, at * 1 0 ("Under 49 U.S.C. 10?’09, we have no authority to regulate rail rates and services that are govemed by a contract Therefore, our findings and actions here apply only to regulated common carrier traffic."); se_e also Fayus Enters. v. BNSF Rv. Co., 602 F`.Sd at 445 (noting that under 49 U.S.C. § 10709 traffic that moves under railroad-shipper contracts generally is not subject to challenge before the STB). And plaintiffs’ putative class in the instant case includes only those shippers who purchased rate-urzregufaled transportation services mSm_e__e; Class Mot. at l. But plaintiffs say that the fuel surcharges applied to rate»regulated freight traffic are the same fuel surcharges applied during the class period to putative class members, §e_e_ Class l\/lern. at 49; 2d Am. Compl. 11 98, and both sides reference the STB decision and rely on it for various propositions in their class certification briefing §_e§ Class Mern. at 49; Class Opp. at l6-l7; Class Reply at 22-25. The Court therefore will describe below the STB proceedings and the STB’s 2002 decision. The STB held hearings on the use of fuel surcharges on rate-regulated traffic in May and August 2006. Rail Fuel Surcharges, 2007 WL 201205, at *l. On january 26, 2007, the STB issued its decision on the matter, concluding: [I]t is an unreasonable practice to compute fuel surcharges as a percentage of the base rates. Because railroads rely on differential pricing, under which rates are dependent on factors other than costs, a surcharge that is tied to the level of the base rate, rather than to fuel consumption for the movement to which the surcharge is applied, cannot fairly be described as inerely a cost recovery iriechanisni. Rather, a fuel surcharge program that increases all rates by a set percentage stands virtually no prospect of reflecting the actual increase in fuel costs for handling the particular traffic to 14 which the surcharge is applied. Two shippers may have traffic with identical iiiel costs, but if one starts out with a higher base rate (because, for example, it has fewer transportation alternatives), it will pay dramatically more in fuel surcharges _I_d. at *4. Thus, the STB directed defendants to change their practice of "coinputing rail fuel surcharges as a percentage of a base rate" on regulated traffic. _Id. at * l. The STB eniphasized, however, that its ruling did not ban all fuel surcharges for regulated traffic. §_ge Rail Fuel Surcharges, 2007 WL 201205, at *6 ("[W]e are not precluding railroads from incorporating as many factors that affect fuel consumption as they wish in calculating fuel surcharges. Nor are we requiring them to incorporate every conceivable such factor, as we agree that would be impracticable."). Under the STB’s decision, a railroad could still choose to implement a fuel surcharge for rate-regulated traffic, but that surcharge "iriust be based upon attributes of a movement that directly affect the amount of fuel consumed." lc_i_. Essentially, the STB imposed the requirement that any fuel surcharge applied by a railroad must have "a reasonable nexus to fuel consuinption." lg. The STB concluded that a fuel surcharge applied as a percentage of a base rate fails that test because it "increases all rates by a set percentage" and therefore "stands virtually no prospect of reflecting the actual increase in fuel costs for handling the particular traffic to which the surcharge is applied." l”d_. at *4. As discussed, the STB decision did not apply to rate-unregulated freight traffic. Nor did the STB decision in any way preclude railroads from using fuel surcharges tied to base rates in private contracts. As the STB noted in its decision: Several carriers introduced evidence that many of their customers favor the continued use of a fuel surcharge program that is tied to the base rate. Given that such a program shifts greater responsibility for fuel recovery to shippers with higher rates, it is 15 not surprising that a subset of customers (presumably those with lower base rates) favor retaining a percentage-of-the-base-rate approach We note that such shippers are free to enter into contractual arrangements with carriers that incorporate into those contracts any escalation provision for fuel cost recovery that the parties wish. Rail Fuel Surcharges, 2007 WL 201205, at *6 n.34. Although some customers of rate-unregulated freight traffic may have favored the use of fuel surcharges tied to base rates, many others did not, and that latter group of shippers had similar complaints to those expressed before the S'I`B. §_e_e Class Meni. at 45~47. Those complaints eventually gave rise to 18 separate class action lawsuits, pending in six districts, involving common antitrust allegations relating to the use of fuel surcharges on rate~unregulated freight traffic. Y Rail freight I, 587 F. Supp. 2d at 29; In re Rail Freight Fuel Surcharge Antitrust Litig., 528 F. Supp. 2d 1358, 1358-59 (J.P.M.L. 2007). On November 26, 2007, the Multidistrict Litigation Panel consolidated those 18 separate class actions and transferred them to this Court, § In re Rail Freight Fuel Surcharge Antitrust Litig., 528 F. Supp. 2d at 1358-.59, and now eight named plaintiffs request that this Court certify this case as a class action under Rule 23(b)(3). _Sg Class Mot. at l~2. C. Class Certi.`jfcati`on Papers cited Supplemeiifal Bri`eji`iig Before and After the Moti`o.=is Heai'iiig As will be discussed in detail below, to obtain class certification plaintiffs must satisfy the four threshold requirements of R.ule 23(a) - commonly referred to as numerosity, commonality, typicality, and adequacy -~ and the two additional requirements of Rule 23(b)(3) i6 predominance and superiority." Althougli there is some dispute over whether plaintiffs have satisfied some of the requirements of Rule 23(a), §§ Class Opp. at 75~82, the parties agree that the central question before the Court relates to predominance, that is, whether plaintiffs have met their burden to show that "questions of law or fact common to class members predominate over any questions affecting only individual niembers[.]" FED. R. Civ. P. 23(b)(3); _s_e_q Defs. Wal-Mart Reply Brief at l; Oct. 6 Tr. at 88; Oct. 7 Tr. at l67. That question, in tum, focuses on whether plaintiffs have shown that the harm ~ that is, the impact ~ from the alleged conspiracy is capable of proof at trial through evidence that is common to the class rather than individual to its members. §§ §;g;, Dcfs. Wal~Mai't Reply Brief at l. Plaintiffs maintain that they will be able to demonstrate the alleged conspiracy’s impact at trial with common evidence. § Class Mein. at 67-75. And in support of their motion for class certification, plaintiffs have submitted for consideration by the Court the expert report of Dr. Gordon Rausser, the Robert Gordon Sproul Distinguished Professor at the University of California at Berkeley. §§ lst Rausser Report at 1. Plaintiffs asked Dr. Rausser to determine, among other things, whether “[t]here was a common impact of Defendants’ alleged conspiracy on the Plaintiffs and the Class which can be demonstrated through evidence and economic analysis common to the Class[.}" _I_d. at 4. Dr. Rausser analyzed the rail freight industry and defendants’ transaction data and concluded that there was such a common iinpact. §§_e i_d_. at 5-8. 4 in addition to the four express requirements of Rule 23(a), there are two implied requireinents: (l) the class must be "sufficiently defined so as to be identifiable as a class"; and (2) the named representatives must "fall within the class." Vigus v. Southern lll. Riverboat/Casino Cruises, Inc., 274 F.R.D. 229, 235 (S.D. Ill. 20l l) (citing Oshana v. Coca-Cola _C_g;, 472 ll.3d 506, 513 (7th Cir. 2006); Alliance to End Repression v. Rochford, 565 F.2d 975, 97? (nh Cir. 1977)). ` 17 As Dr. Rausser explains, he developed economic regressions that he applied to defendants’ transaction data; in view of the results of his regressions, he concludes, among other things, that common evidence and economic analysis can be used to detennine the impact of defendants’ alleged conspiracy on a class-wide basis. _S__@ i_d. at 7~8, 80-81. Defendants oppose plaintiffs’ n'iotion for class certification, arguing primarily that individual issues predominate in detennining the impact of the alleged conspiracy. § Class Opp. at 28-72. in support of their position that class certification is inappropriate, defendants have submitted for consideration by the Court the expert report of Dr. Robert Willig, a Professor of Economics and Public Affairs at Princeton University. §ge Willig Report 1| l. Among other things, defendants asked Dr. Willig to determine "whether it is feasible for plaintiffs to demonstrate through common proof that members of the proposed class suffered economic injury[.]" _l“c_i_. ‘1[ ll. Dr. Willig concludes that it is not feasible; as he sees it, individual issues predominate over common issues for purposes of determining the impact from the alleged conspiracy. ld_. 1[25. According to Dr. Willig, "[e]valuation of plaintiffs’ claims in this matter would require undertaking analysis that is specific to individual plaintiffs." g Furthennore, Dr. Willig contends that Dr. Rausser’s regressions are flawed, and he disagrees with Dr. Rausser’s conclusion that common evidence and analysis can be used to determine the impact of the alleged conspiracy. §. The parties and their experts therefore have presented this Court with what other courts have referred to as a “battle of the experts" on predominance and, in turn, impact. Ellis v. Costco Wholesale Corp., 657 F.Bd 970, 982 (9th Cir. 2011); In re Puerto Rican Cabotage Antitrust Litig., 269 F.R.D. l25, 132 (D.P.R. 2010). Compare lst Rausser Report at 7, with 18 Wiilig Report '|| 25. As plaintiffs see it, they should win this l)attle: whereas Dr. Rausser used economic analysis to show persuasively that workable formulas, common to the class, are available to prove irnpact, Class Reply at l, Dr. Willig’s analysis should not be credited because his methodology is "overtly f`lawed." lgl_. at 5. Defendants say the opposite, arguing that the Court should not credit Dr. Rausser’s analysis because it is "fatally flawed." Class Opp. at 50. ln preparation for the hearing on plaintiffs’ motion for class certification and in view of the disputes between Dr. Rausser and Dr. Willig on the central issue of predominance, the Court concluded that supplemental briefing was necessary. The Court therefore ordered supplemental briefing on two issues, to be completed before the class certification motions hearing: (l) What standard of proof should the Court apply when examining the requirements of Rule 23 of` the Federal Rules of Civil Procedure?; and (2) Can the Court resolve factual disputes relevant to Rule 23 requirements - with particular emphasis on conflicting expert reports m if those factual disputes overlap with the merits of this case? _S_@ Order at l-Z, Sept. 17, 2010 [Dkt. No. 423]. The Court then heard oral argument on plaintiffs’ motion for class certification, including argument on these two supplemental issues, on October 6 and 7, 2010. §"QQ generally Oct. 6 Tr.; Oct. 7 Tr.; w_e § Order at l-2, Oct. 5, 2010 [Dl 552 F.3d 305, 316 n. 14 (3d Cir. 2008); Lindsay v.

Those requirements fall into two categories First, the moving party must show that its proposed suit satisfies the two implied and the four express requirements of l{ule 23(a). _S§_e Vigus v. Southern lll. Riverboat/Casino Cruises, lnc., 274 F.R.D. at 235; Lindsay v. Governnrent Emps. Ins. Co., 251 F.R.D. at 54. As for the implied requirements, plaintiffs must show ( 1) that their proposed class is "sufficiently defined so as to be identifiable as a class"; and (2) that the named representatives "fall within the class." Vigus v. Southern lll. Riverboat/Casino Cruises, Inc., 27'4 F.R.D. at 235. As for the express requirements, the moving party must show that (l) the class is so numerous that joinder of all members is impracticable; (2) there are questions of law or fact common to the class; (3) the claims or defenses of the representative parties are typical of the claims or defenses of the class; and (4) the representative parties will fairly and adequately protect the interests of the class. FED. R. Clv. P. 23(a). Those four express requirements coinmonly are referred to as numerosity, coinmonality, typicality, and adequacy failure to adequately demonstrate any of the Rule 23(a) requirements is fatal to class certification. _S_e_§ Garcia v. Johanns, 444 F.3d 625, 631 (D.C. Cir. 2006). 23 Second, the moving party must show that its proposed suit falls within at least one of the three categories of cases set forth in Rule 23(b). Lindsay v. Goveminent En'ips. lns. Co., 251 F.R.D. at 54. ln this case, plaintiffs move for class certification under Rule 23(b)(3). That part of Rule 23 is intended to encompass cases in which "a class action would achieve econoinies of time, effort, and expense, and promote unifonnity of decision as to persons similarly situated, without sacrificing procedural fairness or bringing about other undesirable results." § at 56 (quoting FE):). R. Clv. P. 23(1)) Aovisoav committee worn ro 1966 AMENDMENTS), In order to certify a class under Rule 23(b)(3), a court must find "[1] that the questions of law or fact common to class members predominate over any questions affecting only individual members, and [2] that a class action is superior to other available methods for fairly and efficiently adjudicating the controversy." FED. R. Clv. P. 23(b)(3). 'l`hese two requirements commonly are referred to as predominance and superiority. As Rule 23(b)(3) states, in deciding whether a moving party has satisfied the predominance and superiority requirements, pertinent considerations for a court include: (A) the class inembers’ interests in individually controlling the prosecution or defense of separate actions; (B) the extent and nature of any litigation concerning the controversy already begun by or against class inembers; (C) the desirability or undesirability of concentrating the ligation of the claims in the particular forum; and (D) the likely difficulties in managing a class action. 24 The Supreme Court has emphasized that a class certification decision invites a "close look at the case," Amchein Prods. lnc. v. Windsor, 52l U.S. 591, 615 (1997) (quotations omitted), and a class may be certified only "if the trial court is satisfied, after rigorous analysis," that the applicable Rule 23 requirements have been met.

McLAUoiiLiN, McLAucnLiN on Cr.Ass AcrioNs § 3: 12 (Sth ed. 2011) ("Until recently . . . there had been surprisingly little case law addressing the evidentiary standard the proponent of certification must meet in demonstrating that Rule 23’s requirements are satislied."); Teamsters Local 445 freight Div.

Jan. 30, 2012), the Supreme Court’s recent decision in Wal-l\/lart as well as persuasive decisions from the Third Circuit and others have clarified the standards that a district court must apply in determining whether to certify a class. Upon review of those decisions, the Court concludes (l) that it can and must resolve any factual disputes relevant to the requirements for class certification - even if that requires considerations 27 enmeshed in the factual and legal issues comprising plaintiffs’ claim on the rnerits, s_e_e Wal~Mart Stores, lnc. v. Dukes, 131 S. Ct. at 255}-52; §e_e also In re l~lydrogen Peroxide Antitrust Litig., 552 F.3d at 32(); and (2) that it should apply a preponderance of the evidence standard of proof in doing so. §_e§, gg¢, in re Hvdrogeii Peroxide Antitrust Litig., 552 F.3d at 320. l. F actual Disputes and Dueiing Experts As the Supreine Court stated in Wal-Mart Stores, lnc. v. Dukes: "Rule 23 does not set forth a mere pleading standard. A party seeking class certification must affirmatively demonstrate his compliance with the Rule _ that is, he must be prepared to prove that there are fnfaci sufficiently numerous parties, common questions of law or fact, etc." Wal-Mart Stores, lnc. v. Dukes, 131 S. Ct. at 2551 (einphasis in original). A district court must be satisi"ied, after "rigorous anaiysis," that the requirements of Rule 23 have been met, and [f]requentiy that rigorous analysis will entail some overlap with the merits of the plaintiff s underlying claim. That cannot be helped. {T]he class determination generally involves considerations that are enmeshed in the factual and legal issues comprising the plaintiff’ s cause of action. . . . Nor is there anything unusual about that consequence[.] Wal-Mart Stores, lnc. v. Dukes, 131 S. Ct. at 2551-52 (quotations and citations ornitted). The Supreine Court in Wal~Mart definitively resolved the question whether its decision in Eisen v. Carlisle & Jacquelin, 417 U.S. 156 (1974), precludes inquiry into the merits at the class certification stage. Before the Supreine Court issued its decision in Wal~l‘\/lart, much of the law on that question arose from an "oft-quoted stateinent" in Eisen, s§_e_ ln re initial Pub. Offering»s Sec. Litig., 4?1 F.3d 24, 33 (Zd Cir. 2006), that “nothing in either the language or history of Rule 23 . . . gives a court any authority to conduct a preliminary inquiry into the inerits 28 of a suit in order to determine whether it may be maintained as a class action." Eisen v. Carlisle & Jacguelin, 417 U.S. at 177. In the past, that statement in Eisen has led some courts to think that in determining whether any Rule 23 requirement is niet, a judge may not consider any aspect of the merits, and has led other courts to think that a judge may not do so at least with respect to a prerequisite of Rule 23 that overlaps with an aspect of the merits of the case. In re initial Pub. Offerings Sec. Litig., 471 F.3d at 33. The Supreme Court in Wa1-Mart made clear that that reading of its decision in Eisen is wrong. As the Supre1ne Court stated: [i]n [Eisen|, the judge had conducted a preliminary inquiry into the merits of a suit, nor in order 10 determine the propriety of certification uiider Rules 23(¢1) and (b) (he had already done that . . . ), but in order to shift the cost of notice required by Rule 23(0)(2) from the plaintiff to the defendants Wal~Mart Stores, lnc. v. Dukes, l3l S. Ct. at 2552 n.6 (etnphasis added) (citation omitted). To the extent that language in _E_i_sie_n suggests the irnperrnissibiiity of a merits inquiry related to the Rule 23(¢1) and (b) anaiysis, the Supreme Court made clear that such language "is the purest dictum and is contradicted by . . . other [Supreme Court] cases." Wal-Mart Stores, lnc. v. Dukes, 131 S. Ct. at 2552 n.6. Thus, "it is appropriate v and indeed necessary - in some circumstances to ‘consider[] a merits question at the Rule 23 stage."’ Kottaras v. Whole Foods Mkt., Inc., 2012 WL 259862, at *6 (quoting Wal-Mart Stores, lnc. v. Dul 482 F.3d 372, 381 (5th Cir. 2007); ln re initial Puhlic Offerings Sec. Litig., 471 F.3d at 41; Gariety v.

Virtually every circuit had expressly adopted standards that require a district court considering class certification to consider evidence" and "resolve factual disputes that are relevant to Rule 23’s criteria[.]"). The required rigorous factual review that a court must perform in examining whether the requirements of Rule 23(a) and (b) have been met similarly applies to disputes among experts relevant to class certification As the Third Circuit stated in 1n re Hydrogen Peroxide Antitrust Litig.: "Expert opinion with respect to class certification, like any matter relevant to a Rule 23 requirement, calls for rigorous analysis." in re Hydrogen Peroxide Antitrust Litig., 552 F.3d at 323. Nothing in Rule 23 distinguishes expert evidence from other types of evidence Under Rule 23 the district court rnust be "satisfied," . . . or "persuaded," . . . that each requirement is met before certifying a class. Like any evidence, admissible expert opinion may persuade its audience, or it may not. This point is especially important to bear in mind when a party opposing certification offers expert opinion. The district court may be persuaded by the testimony of either (or neither) party’s expert with respect to whether a certification requirement is met. Weighing conflicting expert testimony at the certification stage is not only permissible; it may be integral to the rigorous analysis Rule 23 demands in re Hydrogen Peroxide Antitrust Litig., 552 F.3d at 323 (quoting General Tel.

Whole Foods l\/lkt., lpg, 2012 WL 259862, at *11 (quoting ln re Hydrogen Peroxide Antitrust Litig., 552 I~`.3d at 323). There are, of course, liinits to a court’s inquiiy into disputes among experts, just as there are li1nits to a court’s inquiry into factual disputes generally: they should be resolved at the class certification stage only to the extent necessary to "satisf[y]" or "persuade[]" a court that each requirement of Rule 23 has or has not been met. ln re l»lydrogen Peroxide Antitrust Litig., 552 F.3d at 323 (quotations and citations omitted); _s_§_e_ also In re Zurn Pex Plurnbing Prods. Liab. _l__._i*tjg;, 644 F.3d 604, 611 (Sth Cir. 201 l). Thus, for example, a court should only engage itself in 31 "‘statistical dueling"’ of experts if "such dueling presents ‘a valid basis for [granting or] denying class certification."’ Hnot v. Willis G~rp. Holdings Ltd., 241 F.R.D. at 210 (quoting In re lnitial Pub. Offerings Sec. l.itig,4l 7 F.3d at 35). Similarly, for example, a court should resolve "which expert is correct," Cordes & Co. Fin. Servs., lnc. v. A.G. Edwards & Sons, Inc., 502 F.3d at 107, when experts disagree on "wiietiier a single formula can be created, or wlrezher' there really {are] too many factors at work for a multiple regression model to be methodologically sound." g EPDM Antitrust Litig., 256 F.R.D. at 96-97 (citing Cordes & Co. Fin. Servs., lnc. v. A.G. Edwards & Sons lnc., 502 F.3d at 107) (emphasis added). ln contrast, if the defendants’ expert is "merely disputing the res'ulis of the plaintiffs’ experts’ analysis rather than the feasibility of using a single forrnula methodology, that would be a merits issue, not a class certification issue." ln re EPDl\/l Antitrust Litig., 256 F.R.D. at 96 (emphasis added); s_eg i_d. at 100-01 (concluding that defendants’ challenge to plaintiffs’ expert at the class certification stage was a matter to be resolved at trial because, although each sides’ expert "arrived at a polar opposing finding concerning common impact[,] . . . significantly both employ single formulas"). When both experts agree on a methodology for determining class-wide irnpact, but ultimately reach different conclusions whether putative class rnembers were injured by an alleged conspiracy, a court need not resolve which expert is correct at the class certification stage; that dispute presents a inerits question to be resolved by the finder of fact at trial. ln re Currency Conversion Fee Antitrust I.,itig., 264 F.R.D. 100, 115 (S.D.N.Y. 2010); § ln re EPDI\/l Antitrust Litig., 256 F.R.D. at 90; l-Inot v.

Facts Bearing on Rule 23 The Court concludes that plaintiffs must establish the requirements of Rule 23 by a preponderance of the evidence, and that this standard applies to any factual disputes, including those among experts, that bear on the decision whether to certify a class. As both sides acknowledge, in the past some judges in this district at the class certification stage have required plaintiffs to make only a "threshold showing" or to set forth a "colorable method" by which they intend to satisfy the requirements of Rule 23. in re Vitarnins Antitrust Litig., 209 F.R.D. at 264; _sp_e Pls. Supp. Brief at 1~2; Defs. Supp. Brief at 14~15. Recent decisions by the Second, Third, and Fifth Circuits, however, all expressly hold that Rule 23 requirements must be established by a higher standard: a preponderance of the evidence _S_e_e Brown v, Kelly, 609 F.3d 467, 476 (2d Cir. 2010) ("'l"he Rule 23 requirements must be established by at least a preponderance of the evidence.") (citing Teamsters Local 445 Freight Div. Pension v.

Bombardier lnc., 546 F.3d at 202) (alteration in original).s As the Third Circuit stated in ln re Hydrogen Peroxide: [I]nvoking the phrase "threshold showing" risks misapplying Rule 23. A "threshold showing" could signify, incorrectly, that the burden on the party seeking certification is a lenient one (such as a prima facie showing or a burden of production) or that the party seeking certification receives deference or a presumption in its favor. So defmed, "threshold showing" is an inadequate and improper standard [T]he requirements of Rule 23 must be met, not just supported by some evidence. In re Hydrogen Peroxide Antitrust Litig., 552 F.3d at 321 (quotations omitted). "Class certification requires a finding that each of the requirements of Rule 23 has been rnet" by a preponderance of the evidence ln re Hydrogen Peroxide Antitrust Litig., 552 F.3d at 320; _s_e§ FED. R. Clv. P. 23(b)(3) (the court must "find[] that the questions of law or fact coinmon to class members predominate"). A court can only do so upon weighing all relevant evidence for and against class certification and then concluding by a preponderance of the evidence that the Rule 23 requirements in fact have been met. §_qe_ _i_c_:l_. at 320-22; §e§ gl§_q Wal- Mart Stores= lnc. v. Dukes, 131 S. Ct. at 2551 (party seeking certification "inust be prepared to prove that there are infact sufficiently numerous parties, common questions of law or fact, etc.") (emphasis in original). Applying a lesser standard would perrnit class certification even if a court thought it less than likely that each Rule 23 requirement had been met, violating the Supreme Court’s instruction that "actual, not presumed conformance" with Rule 23 is "indispeiisable." 5 ln their supplemental briefing, plaintiffs state that they do not object to the Court applying the preponderance of the evidence standard because they believe they can readily satisfy it; nevertheless, plaintiffs note that they "are not agreeing that a preponderance standard should apply."

Exnert Opinions and Regression Analyses An expert opinion presenting economic regression analysis commonly is used as a basis for certifying a class. Y, _e_.g.“, ln re TFT~LCD (Flat Panel) Antitrust Litig., 267' F.R.D. 291, 313 (N.D. Cal. 201()) (citing cases accepting multiple regression analysis as a means of proving antitrust injury and damages on a class-wide basis); ln re EPDM Antitrust Litig., 256 F.R.D. at 95; g gls,o_ D/\Nlal. L. Runlr~l FELD, REFERENCE Gulna oN Mutrlr>l.lz Raortl~:ssiou 305-08 (Fan. JunlclAL CF.NTER, 3d ed. 2011). ln this case, plaintiffs’ expert, Dr. Gordon Rausser, has developed two multiple regression models, a common factor model and a damage model, that, in his opinion, together reveal that impact can be established at trial with evidence common to the class. §_e_e_ 2d Rausser Report at 9l -92, 99-100; s_e_e §l§o Oct. 6 Tr. at 137. Defendants’ expert, Dr. Rohert Willig, disagrees with Dr. Rausser’s analysis and concludes that Dr. Rausser’s regressions suffer from fatal flaws §ee generally Willig Report. Where, as here, experts disagree on the ultimate question whether an economic regression model shows that impact is capable of proof at trial through evidence common to the class, that disagreement must be resolved by a court at the class certification stage: a court must determine "which expert is correct" about whether "the injury-in»fact question is common to the class." Cordes & Co. Fin. Servs., lnc. v. A.G. Edwards & Sons, lnc., 502 F.Bd at 107; se_e l_r_i___r_e_ l;lvdrogen Peroxide Antitrust Litig., 552 F.3d at 324. To answer that question, the Third Circuit instructed in ln re Hydrogcn Peroxide Antitrust Litig. that a court must apply a two prong test, 35 examining (l) whether the plaintiffs have established that their expert’s theory of common impact is "plausible"; and, if so, (2) whether the plaintiffs have established by a preponderance of the evidence that the expert’s plausible theory is "susceptible to proof at trial through available evidence common to the class." In re Hvdrogen Peroxide Antitrust Litig., 552 F.3d at 325; _s_e§ Behrend v. Comcast Corp., 655 F.3d at 192-93. The Third Circuit recognized in I_n re Hvdrogen Peroxide Antitrust Litig., and then reaffirmed in Behrend v. Cotncast Corp., that an expert’s theory that impact is capable of common proof at trial - by means of regression analysis or other common evidence -;- is not a question of fact necessarily capable of resolution by a preponderance of the evidence. The plausibility standard falls below a requirement of perfection, _s§_je_ Behrend v. Comcast Corp., 655 F.3d at 204 n.13 (a court need not determine that a regression model "is perfect at the certification stage"), and above a "threshold," In re l~lvdrogen Peroxide Antitrust Litig., 522 F.3d at 321 (quotations omitted), or a "not fatally i':lawed" standard In re lnitial Pub, Offerings Sec. Lig;, 471 F.3d at 42. Plausibility depends on the "ability to establish ~»»»» whether through inathematical models or further data or other means - the key logical steps behind [the] theoiy." In re New Motor Vehicles Canadian Exp. Antitrust Litig., 522 F.3d 6, 25-26 (1st Cir. 2008). By way of illustration, Dr. Willig criticizes Dr. Rausser’s coinmon factor regression model for looking at only a snapshot in time and therefore purportedly failing to examine changes in freight rates over time. §ee_ Willig Report jj 213. Whether this purported error discredits Dr. Rausser’s common factor model is not a question that readily lends itself to resolution by a preponderance of the evidence; indeed, such a standard has not been adopted by 36 any court and lacks intuitive force. §e§ Oct. 6 Tr. at 20 (plaintiffs’ counsel noting that "there has been no direction by any circuit, let alone this district or the Supreme Court that applies an evidentiary type standard to the assessment by the court as a whole of an expert report directed at proof of impact or fact of damage and amount of damage"). Instead, applying the first prong of the test set forth in In re Hydrogen Peroxide Antitrust Litig., the Court will evaluate whether this purported error precludes a determination that Dr. Rausser’s theory of proof is "plausible," Behrend v. Comcast Co@., 655 F.3d at 204 n.13; In re Hydrogen Peroxide Antitrust Litig., 552 F.Sd at 325, or "viable," in re New Motor Vehicles Canadian Exp. Antitrust Litig., 522 F.3d at 25 (lst Cir. 2008); and that his regression analysis is "feasible," ln re EPDl\/l Antitrust l,itig., 256 F.R.D. at 96, or "workabie." ln re Ainaranth Natural Gas Commodities Litig., 269 F.R.D. 366, 383 & n.118 (S.D.N.Y. 2010); §e_e in re Readv-i\/Iixed Concrete Antitrust Litig., 261 F.R.D. 154, 171 (S.D. lnd. 2009).° l If a court detennines that the plaintiffs have established that their expert’s theory of proof is plausible and that their expert’s regression analysis, if any, is workable, then the next question for the court to resolve is whether the plaintiffs have established by a preponderance of the evidence that the plausible theory and workable regression are ‘»‘susceptible to proof at trial through available evidence common to the class." ln re Hydrogen Peroxide Antitrust Litig., 552 'F.3d at 325; _s_e§ Behrend v. Comcast Corp., 655 F.3d at 192-93. In assessing that question in this ° Defendants use the terms "feasible" and "viable" in evaluating the issue of common i1npact. § Willig Report 'll ll (stating that defendants asked Dr. Willig to determine "whether it is feasible for piaintiffs to demonstrate through common proof that members of the proposed class suffered economic injuiy") (emphasis added); Defs. Wal-Mart Reply Brief at 1 (stating that the central question before the Court is whether plaintiffs have proffered "a triable classwide method for proving injury at trial") (emphasis added). 37 case, the Court will resolve all factual disputes bearing on Dr. Rausser’s and Dr. Willig’s analyses - including what the parties refer to as subsidiary factual disputes underlying the experts’ opinions ~»~ by a preponderance of the evidence. §_e§ In re Hydrogen Peroxide Antitrust _L_it_ig, 522 F.3d at 320~25; _s_ee Oct. 6 Tr. at 30-31. And ultimately, the Court will determine which expert is correct, Dr. Rausser or Dr. Willig, on the question whether a workable regression model can be used to establish by a preponderance of the evidence that impact can be proven at trial with common evidence. Y, §g;, Behrend v. Comcast Corp., 655 F.3d at 192-93; lg;e_ Hydrogen Peroxide Antitrust Litig., 522 F.3d at 325; Cordes & Co. Fin. Servs., Inc. v. A.G. Edwards & Sons, lnc., 502 F.3d at 10'7. To summarize, the Court will resolve factual disputes relevant to Rule 23 requirements, and the Court will apply a preponderance of the evidence standard in examining whether plaintiffs have satisfied each of the requirements of Rule 23. Accordingly, in order to certify plaintiffs’ putative class, the Court "must find that the evidence more likely than not establishes each fact necessary to meet the requirements of Rule 23." n re Hydrogen Peroxide Antitrust Litig., 552 F.3d at 320; _s_ee also Behrend v. Corncast Corp., 655 F.?)d at 185 (plaintiffs must establish by a preponderance of the evidence that they would be able to prove through common evidence impact and a common inethodology to quantify damages). As for the predominance requirement of Rule 23(b)(3), in examining Dr. Rausser’s conclusion that impact can be established at trial with common evidence, the Court will determine whether Dr. Rausser’s theory of proof is plausible and whether his regression models are workable; and, if so, 38 whether plaintiffs have established by preponderance of the evidence that his theory and models are "susceptible to proof at trial through available evidence common to the class." In re Hydrogen Peroxide Antitrust Litig., 552 F.3d at 325; § Behrend v. Comcast Corp., 655 F.3d at 192~93. Defendants contend that there are numerous factual disputes between the parties and their experts that are relevant to whether plaintiffs have satisfied the predominance requirement of Rule 23(b)(3), and defendants further contend that Dr. Rausser’s analysis is fatally tlawed. Defendants identify four principal factual disputes and assert that each one bears on whether impact can be proven at trial with common evidence: (l) whether rate~based fuel surcharges frequently were used before the class period, ge Defs. Wal-Mart Brief at 5; (2} whether "legacy shippers" »- that is, shippers who paid a rate-based fuel surcharge during the class period under a contract that was entered into before July l, 2003 we would have continued paying fuel surcharges, even absent the alleged conspiracy, §;e__e_ i_c_i_.; §§_e §tl§g Defs. Supp. Brief at 17; (3) whether captive shippers - that is, those shippers served by only one railroad or those shippers with no viable transport alternatives to the railroad that serves it a~ would have paid fuel surcharges, even absent the alleged conspiracy, §§:§ Defs. Wal-Mart Brief at 6; Defs. Supp. Brief at 18 & n.l0; and (4) whether some class inembers received concessions from a defendant on certain aspects of their rail transportation agreement in exchange for acceptance of the defendant’s fuel surcharge. § Defs. Wal-l\/lait Brief at 6; Defs. Supp. Brief at 19. As defendants describe it, the Court’s resolution of each of these factual disputes in plaintiffs’ favor is a necessary condition for class certification; defendants contend that these disputes "must be resoived" in examining whether to certify plaintiffs’ putative class. Defs. Wal-Mart Brief at 6; §§ Defs. Supp. Brief at 19»20. 39 The Court agrees with defendants that these factual disputes are relevant to Rule 23(b)(3)’s predominance requirement -»- primarily, whether plaintiffs can show that impact is capable of proof at trial through evidence that is common to the class. Regarding, for example, the issue lof concessions, if shippers received concessions in the form of base rate discounts in exchange for the application of a fuel surcharge, then, as plaintiffs’ expert himself acknowledges, the impact for those shippers "wouldn’t have been common to others" who did not receive such discounts. lst Rausser Dep. at 2'/'2; _s_§e §§ i_d. at 270 (Dr. Rausser, acknowledging that "any coordinated program that focuses just on a part of the pricing can be unwound or made far less effective if there is a change in the base pricing"). Going further, if the fuel surcharge applied to a shipper "was exactly offset by the base rate," then, as plaintiffs’ expert states, "there would be no injury." 2d Rausser Dep. at 208.7 Defendants and their expert contend that some shippers included within plaintiffs’ class were not harmed by the alleged conspiracy because they received contract concessions in the form of base rate discounts. And defendants say that determining which shippers received such discounts requires individualized evidence and analysis that precludes a finding that impact can be proven on a class-wide basis with common evidence. Plaintiffs and their expert disagree, 7 To be clear on terms, as discussed below, such an exact offset between a fuel surcharge and a base rate would mean that an individual plaintiff has no claim for damages, but not necessarily that that plaintiff was not injured by the defendants’ alleged conspiracy. Y, _e”.,g;, in re EPDM Antitrust Litig., 256 F.R.D. at 88 ("[l]t is possible for a plaintiff to suffer antitrust injury-in-fact and yet have no damages because it has taken steps to mitigate the actual price paid through rebates, discounts, and other non-price factors . . . . By expending resources to negotiate down from the supracomeptitive prices established by the caitel, plaintiffs who have suffered no damages may still have suffered an injury-in-fact from the antitrust conspiracy. The fact that a plaintiff may have successfully employed bargaining power to fend off the ejj"fecl of the conspiratorial practices does not mean that it has not been put in a worse position but-for the conspiracy.") (emphasis in original); §e§ i_nf£ at 1 l5-l6. 40 arguing that there is no evidence of widespread discounting and any examples of discounting are anomalies that do not preclude a finding that impact can be proven on a class-wide basis with cornmon evidence. Because this dispute is relevant to whether common evidence can be used to establish impact at trial, the Court must resolve it by a preponderance of the evidence - even though it plainly is an issue enmeshed in the factual and legal issues comprising the merits of plaintiffs’ claiin. Although the Court agrees with defendants that it must resolve this (and other) factual disputes, the Court disagrees with defendants that the facts fall in their favor at this stage. As discussed below, the Court finds by a preponderance of the evidence that the fuel surcharge programs applied by defendants before the class period were nothing like the widespread application of defendants’ more aggressive, standardized fuel surcharge programs during the class period; that these standardized fuel surcharges were applied uniformly, to all or virtually all class niembers; and that there is no evidence of widespread discounting of base rates in exchange for application of fuel surcharges, and that any such discounting in the record is an anomaly that does not preclude a finding of predominance. Furtheiinore, the Court credits Dr. Rausser’s conclusion that impact and damages are capable of proof at trial with common evidence. The Court finds that Dr. Rausser’s economic regression analysis is workable, and that he presents a theory of proof that is plausible and susceptible to proof at trial through available evidence common to the class.“ 8 The findings set forth in this Opinion are made "only for purposes of class certification and [are] not binding on the trier of facts" on the merits at trial. ln re lnitial Pub.

Class Definition The first implied requirement of Rule 23(a) is that the class must be "sufficiently defined so as to be identifiable as a class." Vigus v. Southern lll. Riverboat/Casino Cruises, lnc., 274 F.R.D. at 235; see also Johnson v. District ofColumbia, 248 F.R.D. 46, 52 (D.D.C. 2008); Pigford v. Glickinan, 182 F.R.D. 341, 346 (D.D.C. 1998). "The requirement that a class be clearly defined is designed primarily to help the trial court manage the class." Pigford v. Glicl 218 F.R.D. 262, 269 (S.D. Fla. 2003); §§ also johnson v. District of Colunibia, 248 F.R.D. at 52. fn this case, plaintiffs seek certification of the following class: All entities or persons that at any time from July l, 2003 until December 31, 2008 (the "Class Period") purchased rate-unregulated rail freight transportation services directly from 42 one or more of the Defendants, as to which Defendants assessed a stand-alone rail freight fuel surcharge applied as a percentage of the base rate for the freight transport (or where some or all of the fuel surcharge was included in the base rate through a method referred to as "rebasing") ("Fuel Surcharge"). Excluded from this Class definition are (a) Defendants, any subsidiaries or affiliates of Defendants, any of Defendants’ co~conspirators, whether or not named as a Defendant in the Co1nplaint, and all federal governmental entities, and (b) all entities or persons that paid a Fuel Surcharge directly to any of the Defendants solely pursuant to a railroad-shipper contract that was (i) entered into before July l, 2003, and (ii) provided for a stand~alone Fuel Surcharge to be paid under a predetermined formula specifically set forth in the contract. Class Mot. at l.° Defendants contend that plaintiffs’ class definition "renders determining which shippers would actually be in the proposed class extremely difficult, if not impossible." Class Opp. at 75. According to defendants, there are two problems with plaintiffs’ proposed ciass: 9 During the class certification motions hearing, the Court noted that the class definition proposed by plaintiffs in their motion papers is different from the class definition proposed by plaintiffs in their second consolidated amended complaint. _Se_e Oct. 7 Tr. at 331. Compare Class Mot. at l, _w_i_tl_i_ 2d Am. Co1npl. ‘\] 38. In view of some case law suggesting that a district court may be bound by the class definition set forth in a complaint, §eg Berlowitz v. Nob Hill Masonic Mgmt., Inc., Civil Action No. 96~1241, 1996 WL 724776, at *2 (N.D. Cal. Dec. 6, 1996); _s§_e gl§o Brewer v. Salyer, Civil Action No. 06-1324, 2009 WL 2019923, at *3 (E.D. Cal. July 8, 2009), the Court directed two questions to the parties at the motions hearing: (l) How do the plaintiffs want the class defined?; and (2) ls there some obligation on the plaintiffs to move to amend their amended complaint to match the definition set forth in the class certification motion? _S~e_e Oct. 7 Tr. at 331. ln response to the Court’s two questions, the parties filed a joint submission regarding the class definition in which they agreed that a formal amendment to plaintiffs’ complaint was "not necessaiy" and that the Court "may decide plaintiffs’ motion for class certification based on the proposed class definition in the motion, and on the record before it." Joint Class Definition Subinission at I. .ln accordance with the parties’ joint submission, the Court has decided plaintiffs’ motion for class certification based on the proposed class definition in their niotion, not the definition in their second consolidated amended complaint. 43 (l) there is no "{e]asy [w]ay" to determine whether freight traffic qualifies as rate-unregulated, i_d.; and (2) plaintiffs propose no method to identify shippers with "rebased" rates. I_d. at 76. As discussed, plaintiffs’ proposed class is specifically limited to "rate-unregulated" traffic. Class Mot. at l. Plaintiffs have defined the term "unregulated" as referring to "rail freight transportation services where the rates are set by private contracts or through other means exempt from rate regulation under federal law." 2d Am. Compl. 11 l. Defendants contend that it is difficult to discern whether freight traffic moves under a regulated common carrier authority or, instead, under an unregulated contract. Class Opp. at 7'5. According to defendants, determining whether freight traffic is rate~regulated or rate-unregulated requires individualized inquiries viewed in light of the parties’ intent. ld_. Consequently, defendants contend that "[d]etennining class membership would require individualized inquiries, inaking class certification inappropriate." ld_. at 76. The Court disagrees with defendants. As plaintiffs point out, the STB ruling in 2007 distinguished between rate-regulated and rate-unregulated traffic, expressly stating that its ruling applied only to the foriner. §§ Class Reply at 39. Neither the STB nor defendants asserted that it was too difficult to determine which traffic the ruling covered l_d. Furthermore, in this case defendants have produced during discovery transaction data for rate-unregulated traffic without arguing that it was too difficult to determine which transaction data related to that type of traffic. l_d. And finally, defendants’ expert, Dr. Willig, has not claimed any difficulty in distinguishing between rate-regulated and rate-unregulated traffic. "fo the contrary, Dr. Willig was able to quantify both the arnount of rate-unregulated traffic during the class period and the revenue it produced for defendants _S__e_e Willig Report 11 24 ("[S]hippers of unregulated traffic 44 with revenue-based FSCsf, that is, fuel surcharges, ]generated roughly 72 million carloads of rail traffic during the class period and $ l 10 billion in revenue for def`endants. This reflects roughly 56 percent of defendants’ total non-regulated traffic over this period, For the class period as a whole, there were nearly 30,000 shippers of unregulated traffic with revenue-based FSCS[.]"); §:_e gl_s_g_ lst Rausser Report at 89 (noting that "the data supplied by BNSF . . . records whether the shipment was regulated or not"). Dr. Willig’s report therefore belies defendants’ claim that it is too difficult to determine whether rail traffic qualifies as rate-unregulated Defendants’ second argument focuses on plaintiffs’ proposed inclusion of shippers who paid "rebased" rates. As plaintiffs describe it, at some point during the alleged conspiracy NS “engaged in something that has come to be known in this case as rebasing; namely folding at least part of the fuel surcharge into the base rate." Oct. 6 Tr. at 133. Defendants contend that plaintiffs "do not identify . . . shippers" who paid a rebased rate "or propose any methodology for doing so." Class Opp. at 76. And in the absence of any viable methodology, defendants contend that it is impossible to determine what shippers are in the class due to rebasing. E. The Court disagrees with defendants Plaintiffs assert that shippers who paid a rebased rate simply paid a new base rate with a portion of the previous supra-competitive fuel surcharge "bal 903 F.2d 176, 180 (2d Cir. 1990) ("[T]here is a danger that absent class members will suffer if their representative is preoccupied with defenses unique to it."). Spoliation of evidence constitutes a unique defense, and courts have concluded that in some circumstances defending against a charge of spoliation of evidence can render a 51 plaintiff an inadequate class representative. §§e, _e_.g;, Falcon v. Philips Elecs. N. Am. Corp., 304 I~`ed. App’x 896, 897 (2d Cir. 2008) (district court did not abuse its discretion in concluding that defending against a charge of spoliation rendered a plaintiff an inadequate class i'epresentative). The presence of a unique defense, however, "will not . . . destroy typicality [unless it] wilt skew the focus of the litigation and create a danger that absent class members will suffer if their representative is preoccupied with defenses unique to it." Meiier, lnc. v. Warner Chilcott Holdings Co. Iil, 246 F.R.D. at 302 (quotations omitted) (alteration in original). in this case, the Court agrees with plaintiffs that at this stage the spoliation issue is hypothetical and speculative, se_e Class Reply at 39, and the Court is satisfied that this alleged unique defense presents a question of law and fact ‘°that can readily be resolved by the Court without skewing the focus of the litigation or creating a significant danger of distracting [plaintiffs’] ability to pursue the interests of the absent class members." Meiier, lnc. v. Warner Chilcott Holdings Co. III, 246 F.R.D. at 302 (quotations omitted). Finally, defendants argue that a "significant number" of putative class inembers’ contracts include broad arbitration clauses §p_e Class Opp. at 7'8. Defendants state that they "intend, as they have a right to do, to rely on [those putative class members’] agreements to arbitrate," which would include, according to defendants, the Shei‘man Act claim alleged in this case. Q. at 7'8-79. Thus, defendants argue that shippers whose contracts include arbitration provisions cannot pursue their claims in this Court and, as a result, cannot be part of the class that plaintiffs seek to certify here. id at 79. And defendants assert that the Court should consider these agreements to arbitrate 4a constituting, as defendants see it, affirmative defenses 4a in making its class certification decision. _iu_d_. (citing Rodnev v. Northwest Airlines, lnc., 52 146 Fed. App’x 783, 786 (6th Cir. 2005). Defendants do not assert, however, that any of the eight named plaintiffs have contracts containing arbitration clauses; nor do defendants assert that they have initiated any arbitrations §__qe_ Class Reply at 40. While defendants do not suggest under what part of Rule 23 the Court should consider their argument regarding arbitration, courts generally have considered the question of defenses in the context of examining the typicality and commonality requirements of Rule 23(a), as well as the predominance requirement of Rule 23(b)(3). §§_:_e_, §g;, fn re Schering Plough Corp. ERISA Litig., 589 F.3d at 598 (question of unique defenses is an offshoot of typicality requirement); Gene & Gene LLC v. BioPay LLC, 541 F.3d 318, 327 (5th Cir. 2008) ("[T]he predominance of individual issues necessary to decide an affirmative defense may preclude class certification.") (quotations ornitted); Gunnells v. Healthplan Servs., Inc., 348 F.3d 417, 438 (4th Cir. 2003) ("[A]ffinnative defenses must be factored into the calculus of whether common issues predominate."). Regardless of which part of Rule 23 applies, however, the Court concludes that "the possible arbitration of some class mernbers" does not, "by itself, defeat class certification." Lemer v. l:~laimsohn, 126 F.R.D. 64, 66 (D. Colo. 1989) (emphasis added). Neither plaintiffs nor defendants have initiated arbitration, and the Court concludes that defendants’ assertion regarding their "inten[t]" to initiate arbitration, Class Opp. at 78, is too speculative to defeat predoininance, much less commonality or typicality. The Court finds that the claims of the eight named class representatives arise from the "same events, practice, or conduct, and are based on the same legal theory as those of other class inerribers." Lindsay v. Govemment Emps. lns. Co., 251 F.R.D. at 55 (quotations omitted). Consequently, piaintiffs have satisfied their burden of showing by a preponderance of the 53 evidence that "the claims or defenses of the representative parties are typical of the claims or defenses of the class[.]" FED. R. CIV. P. 23(a)(3). 4. Adequacy of Representation 'i`he fourth and final express requirement of Rule 23(a) is adequacy lt requires that "the representative parties will fairly and adequately protect the interests of the class." FED. R. Civ. P. 23(a)(4). Thus, this requirement "necessitates an inquiry into the adequacy of representation, including the quality of class counsel, any disparity of interest between class representatives and members of the class, communication between class counsel and the class and the overall context of the litigation." Pigfoi‘d v. Glickman, 182 F.R.D. at 350. "A proposed representative is ‘adequate’ if (l) his interests do not conflict with those of other class meinbers, and (2) he will vigorously prosecute the interests of the class through qualified counsel." Lindsay v. Govemment Emps. Ins. Co., 251 F.R.D. at 55. Plaintiffs assert that the eight named representative plaintiffs have shown a willingness to step forward, incur substantial discovery burdens, and prosecute this case in the best interests of the members of the putative class. Class Mem. at 61. Furthermore, plaintiffs assert that there are no conflicts with the unnamed members of the class that would warrant denial of class certification lt_l. Finally, plaintiffs contend that they have protected the interests of absent class members through the selection of qualified class counsel. As plaintiffs describe it, interim co-lead class counsel Quinn Emanuel and Hausfeld - firms that have extensive experience in both antitrust litigation in particular and class action litigation generally -»~- have vigorously prosecuted this action, expending substantial time and resources in investigating the clainis, overseeing the production 54 and review of doeuments, taking and defending of depositions, working with experts, and briefing and arguing motions. _I_d_. at 62. Defendants present mostly the same arguments regarding adequacy as they did for typicality. _S__e_§ Class Opp. at 79~80. For the reasons just discussed, _s__e,_i; s_gp@ at 49-54, the Court rejects them. ln addition, defendants argue that Donnelly Commodities, lnc. should be disqualified because it filed for bankruptcy and is currently under the control of an appointed trustee. Class Opp. at 81-82. According to defendants, when a class representative has filed for bankruptcy under Chapter 7 and has had a trustee appointed, an "‘inherent’ conflict of interest exists.” §. at 82 (quoting Dechert v. Cadle Co., 333 F.3d 801, 803 (7th Cir. 2003)). As defendants see it, this is because of the trustee’s "‘dual role as class representative and creditors’ representative."’ _I_d. (quoting Dechert v. Cadle Co., 333 F.3d at 803). But the authority upon which defendants rely for that proposition, Dechert v. Cadle Co., rejected a "flat rule that a trustee in a bankruptcy . . . can never be a class representative." Dechert v. Cadle Co., 333 F.3d at 803. And other courts have allowed such representation where, as here, "an additional representative [is designated] to appear as plaintiff along with the Trustee[.}" Ernst & Ernst v. U.S. Dist. Court for the S. Dist. of'l`ex., 457 F.2d 1399, 1400 (5th Cir. 1972). In this case,.of course, there are eight representative plaintiffs only one of which, Donnelly Commodities, Inc., is under the control of a trustee in bankruptcy The Court therefore sees no basis at this stage to disqualify Donnelly Commodities, lnc. as a named representative Finally, as for the quality of class counsel, the Court agrees with plaintiffs’ undisputed assertion that they have protected the interests of absent class members through the 55 selection of class counsel. §e§ Class Mem. at 62-63. As the Court previously has stated, the firms Quinn Emanuel and Hausfeld both have sufficient resources and expertise to prosecute this matter in the putative class’ best interests. §§ Memoranduin Op. & Order at 3, Mar. l3, 2009 [Dkt. No. 232]. As plaintiffs state: Quinn Emanuel and l~lausfeld LLP have already demonstrated their ability to work well together, coordinate the efforts of the various other firms also representing plaintiffs in this multidistrict litigation, and generate work product at the highest professional levels. "i`ogether, these finris are extraordinarily well situated to assess how Plaintiffs’ case will be presented at trial, and will be prepared to try this case should that be necessary Class Mem. at 63. Defendants do not disagree, and neither does this Court.'° The Court finds that plaintiffs have met their burden of showing by a preponderance of the evidence that "the representative parties will fairly and adequately protect the interests of the class," FED. R. Civ. P. 23(a)(4}, because the interests of the eight named representatives do not conflict with those of other class members, and because they will vigorously prosecute the interests of the class through qualified counsel. Lindsay v. Govemment Emps. Ins. Co., 251 F.R.D. at 55. V. RULE 23(b)(3) FlNDlNGS AND CONCLUSIONS Because plaintiffs have satisfied all of the threshold Rule 23(a) requirements by a preponderance of the evidence, the Court now must conduct a "rigorous analysis" of the requirements of Rule 23(b)(3). g ln re Zurn Pex Plumbing Prods. Liab. Litig., 644 F.3d at 6l l; '° Under Rule 23(c)(1)(B) and (g), plaintiffs seek formal designation of Quinn Emanuel and Hausfeld as co-lead class counsel. §_ee_ Class Mot. at 2; Class Mem. at 62 n.219. Upon consideration of the matters set forth in Rule 23(g), the Court will grant plaintiffs’ request and will designate these two finns as co-lead class counsel. 56 Madison v. Chalmette Refining I_,.L.C., 637 F.3d 551, 554 (5th Cir. 201 l); §§ a_ls_p_ Wal-Mart Stores, Inc. v. l)ukes, 131 S. Ct. at 255 l. ln examining whether plaintiffs have satisfied their burden under Rule 23(¥))(3), the Court has resolved the factual disputes between the parties and their experts that are relevant to the requirements for class certification m even when such resolution requires considerations enmeshed in the factual and legal issues comprising the plaintiffs’ claim on the merits - and the Court has applied a preponderance of the evidence standard of proof in doing so. A. Predomr`narice Rule 23(b)(3) requires that the Court "find[] that the questions of law or fact common to class ineinbers predominate over any questions affecting only individual inembersf.]" FED. R. Clv. P. 23(b)(3). As discussed, _s§q s_iipr_g at 25, in examining the predominance requirement under Rule 23(b)(3), a court’s rigorous analysis "‘begins . . . with the elements of the underlying cause of action."’ Messner v. Northshore Univ. HealthSvstein, 669 F.3d at 8l5 (quoting Erica P. john Fund, lnc. v. Haliburton, Co., 131 S. Ct. at 2184). The Court must "scrutinz[e] plaintiffs’ legal causes of action to determine whether they are suitable for resolution on a classwide basis." McCarthy v. Kleindienst, 741 F.2d 1406, 1412 n.6 (D.C. Cir. 1984). The Court therefore examines "the elements of plaintiffs’ claim through the prism of Rule 23 to determine" whether plaintiffs have satisfied the predominance requirement in re Hydrogen Peroxide Antitrust Litig., 552 li.3d at 311 (quotations omitted). if proof of the essential elements of the claim requires individual treatment, then common questions do not predominate and class certification is "iinsuitable." id (quotations oinitted). 57 ln this case, plaintiffs allege that defendants engaged in price tixing, in violation of Section 1 of the Sherman Act. Thus, to prevail on the merits of their claim at trial, plaintiffs will have to prove three elements: ( l) a violation of the antitrust laws »- here, Section 1 of the Sherinan Act; (2) individual impact resulting from that violation; and (3) measurable dainages. _S_Q<_»: In re Hydrogen Peroxide Antitrust Litig., 552 F.3d at 311. At the class certification stage, plaintiffs’ burden is different plaintiffs must show by a preponderance of the evidence that the elements of their claim are "capab!e ofproof`at trial through evidence that is common to the class rather than individual to its inembers." lpl_. at 311-12 (emphasis added). l.

And the parties agree that this element of plaintiffs’ claim is capable of proof at trial through evidence that is common to the class. §§ Class Mem. at 65-66; _s_e§ Oct. 7 Tr. at 161 (defendants’ counsel, acknowledging that "whether there was or was not a conspiracy is in fact capable of common proof, so that’s really not at issue in the predominance analysis"). That is because plaintiffs’ allegations of price fixing indisputably "will focus on the actions of the defendants, and, as such, proof for these issues will not vary among 58 class ineinbers." ln re Vitaniins Antitrust Litig., 209 F.R.D. at 264; ge Meijer= lnc. v.

The Court therefore finds by a preponderance of the evidence that the first eleineiit of plaintiffs’ claim is capable of proof at trial through evidence that is common to the class rather than individual to its members. 2. impact In this case, as in many antitrust cases, the second element of plaintiffs’ claim - individual impact resulting from the alleged conspiratorial conduct (also referred to by the parties as "injury") _ is the central issue. _$me_e Oct. 6 Tr. at 9; Defs. Wal-Mart Reply Brief at 1 ("The parties . . . agree that the central question here is whether Plaintiffs have met their burden . . . to show that common questions predominate over individual ones, which in turn requires that they proffer a viable classwide method for proving injury at trial."); gee also ln re Hydrogen Peroxide Antitrust Litig., 552 F.3d at 31 1. ln examining whether impact is capable of common proof, it is important to note at the outset that this element involves two distinct components: injury~in-fact; and antitrust injury. § Bassett v. National Collegiate Athletic Ass’n, 528 F.Sd 426, 434 (6th Cir. 2008) ("[A] private antitrust plaintiff in addition to having to show injury~in-fact and proximate cause, must allege, and eventually prove, antitrust injui"y.") (quotations omitted); Cordes & Co. Fin. Servs., lnc. v. A.G.

Supp. 588, 590 (D.D.C. 1988) (discussing the "two-fold requirement of individual economic injury to [a] plaintiff that is grounded in the antitrust laws"). These two components pose "two distinct questions": injury-in-fact presents the "fainiliar factual question whether the plaintiff has indeed suffered harm," whereas antitrust injury presents "the legal question whether any such injury is the ‘injury of the type the antitrust laws were intended to prevent and that flows from that which makes defendants’ acts unlawful."’ Cordes & Co. Fin. Servs., Inc. v, A.G. Edwards & Sons Inc., 502 F.3d at 106 (quoting Brunswick Corp. v. Pueblo Bowl-O~Mat, Inc., 429 U.S. 47?, 489 (1977)). Antitrust injury is injury to competition, not just injury to an individual Andrx Pharins., lnc. v. Biovail Corp. Int’l, 256 F.3d '799, 812 (D.C. Cir. 2001). And the reason an antitrust plaintiff is required to prove antitrust injury is to ensure that a plaintiff can recover "only if the loss stems from a competition-reducing aspect or effect of the defendant’s behavior." Atlantic Richfield Co. v. USA Petroleum Co., 495 U.S. 328, 334 (1990) (emphasis in original). 1. lrvjury-irr-fact. The primary dispute in this case relates to the injury-in-fact coinponent of the impact element The parties vigorously dispute whether injury~in-fact can be established at trial with coinmon evidence, and they have submitted expert reports by distinguished economists that reach diametrically opposed conclusions Plaintiffs contend that they will prove injury-in~fact on a class-wide basis at trial "by showing that Defendants’ conspiracy caused the Class members to pay supra-co1npetitive prices during the Class Period." Class Mem. at 67. According to plaintiffs, the effect of defendants’ alleged conspiracy was to impose "on all Class members coordinated Fuel Surcharges that rose in lockstep and resulted in across-the-board prices increases." i_d_. at 68. 60 Plaintiffs assert that they wilt show injury-in-fact "with public information, Defendants’ documents, and witness testimony" - all of which, they contend, wilt be evidence that is common to the class. Class Mem. at 70. Specifically, plaintiffs assert that common evidence will show at trial that l_d. (citations omitted). Defendants intended to use their coordinated Fuel Surcharge programs not as a means solely to recover fuel costs, but as a means to raise revenues and profits Defendants[] intended their coordinated fuel surcharge programs to be applied across~the-board. Defendants each, and in coordination with each other, undertook during the Ciass Period to monitor success in achieving broad application o[f] the Fuel Surcharges. Defendants during the Class Period adopted policies precluding discounting to offset the Fuel Surcharges. Defendants recognized in internal documents that during the Class Period, the Fuel Surcharges generated revenues by raising prices paid by the Class far beyond Defendants’ actual fuel costs. During the Class Period, the Fuel Surcharges were responsible in large part for very large increases in Defendants’ revenues and profits Plaintiffs further contend that the analysis of their expert, Dr. Gordon Rausser, confirms that injury-in-fact can be established at trial with common evidence and economic analysis _Sg Class Me1n. at 71 ." Dr. Rausser explains that he has examined the rail freight " Dr. Rausser provides a detailed discussion of his qualifications and background in his expert report. _S_r§ lst Rausser Report at l-2. ln suinmary, Dr. Rausser is the Robert Gordon Sproul Distinguished Professor at the University of California at Berkeley and the former Dean of that University’s College of Natural Resources.

Furthennore, Dr. Rausser has developed two economic regression models and has analyzed 100 percent of defendants’ transaction data during the alleged conspiracy. 2d Rausser Report at 91~92, 96. Dr. Rausser’s regression analyses purportedly substantiate his theory of coinmon proof, showing that I [Defendants] did implement a common rate increase across the Class through their use of the fuel surcharge applied as a percentage of base rates. l Common factors such as shipment weight, distance, route and commodity type, among others, predominate over individual factors in the determination of freight rates. These common factors can be measured using the Defendants’ transaction data and used in a common analysis to identify and quantity the harm experienced by the Class. l Defendants’ transaction data reveals that there was no material discounting of base rates to offset the fuel surcharges that were applied to shipments made by the Class. As a result, Class rnembers commonly experienced price increases from the Defendants’ actions irrespective of the commodity they were shipping. . . . l Class members paid significantly higher prices to Defendants for rail freight transportation during the Class Period than before and that these higher prices are not explainable by price determinants other than the conspiracy. focuses on the subjects of economics, applied economics, econometrics, and statistics §c;§ § He has published more than 250 aiticles, books, and book chapters, and has written more than l00 conimissioned papers, governmental repoits, and work papers. _I”t_l_.

Id. 62 lst Rausser Report at '7~8. Thus, according to Dr. Rausser, "[t]here was a common impact of Defendants’ alleged conspiracy on the Plaintiffs and the Class which can be demonstrated through evidence and economic analysis common to the Class[.]" lst Rausser Report at 4. Defendants disagree that injury-in-fact can be proven at trial with common evidence. As defendants frame the issues, in order to demonstrate that plaintiffs’ claims are suited for class treatment Plaintiffs must prove . . . that they have a method of providing a common answer to each of the core questions each class member would have to answer had it brought its own claim: (i) Dz`a*` Ipay a fuel surcharge (or higher fuel surchar'ge) because of the alleged corrspir‘acy? and (ii) Dz'd paynzeni of a fuel surcharge cause me to pay morefor shipping than it would have otherwise paia'? Defs. Wal-Mart Brief at 2 (emphasis in original). Defendants contend that the facts in this case make clear that rate-based fuel surcharges were widely used before the start of the alleged conspiracy; that the use of fuel surcharges was growing; and that even Dr. Rausser concedes that some class inembers would have paid rate~based fuel surcharges absent the alleged conspiracy. _S__t_:_e_ _i_c“l. Given these proffered facts, among others, defendants conclude that neither plaintiffs nor their expert "has offered any way to use common evidence to show that, absent the alleged conspiracy, every shipper would have paid a lower fuel surcharge or none at all." ld_. According to defendants, plaintiffs therefore have failed to show that they have a common answer to the first question quoted above. _I_c_l_. As for the second question quoted above, defendants contend that it, too, cannot be a.nswered with common evidence. According to defendants, the facts show that "many shippers received contract concessions, including lower base rates than the railroads initially 63 offered, in exchange for accepting a fuel surcharge[.]" Defs. Wal-Mart Brief at 6. Because the alleged conspiracy was only directed at a portion of the total price of shipping, defendants say that any class member who obtained anything of value in exchange for accepting a fuel surcharge may not have suffered injury-in-fact. §_e_e Class Opp. at 4l. And in view of the purported evidence that "soine (but not all) shippers made trade~offs for fuel surcharges," i_d., defendants contend that individualized issues predominate because "it is necessary to examine the circumstances and negotiating history of each shipper to prove that it did not negotiate offsetting savings and therefore pay a higher all-in price for shipping as a result of its having agreed to a fuel surcharge.” Defs. Wal-Mart Brief at 2. In support of their position that class certification is inappropriate in this case, defendants have submitted the expert report of Dr. Robert Willig.‘z As Dr. Willig explains, he was asked by defendants to address from an economic perspective "whether it is feasible for plaintiffs to demonstrate through common proof that members of the proposed class suffered economic injury"; "whether it is feasible to estimate each class member’s damages on a class-wide basis"; and "to evaluate the damage methodology proposed by Professor Rausser as well as the analyses that support his conclusions." Willig Report 1| ll. ‘2 Dr. Willig provides a detailed description of his qualifications and background in his expert report. § Willig Report 1{1] l-6. in summary, Dr. Willig has been a Professor of Econoinics and Public Affairs at Princeton University for over 30 years. Class Opp. at 6 n.2. He has written 75 articles on economics and a book on competition and the theory of industrial market structure _Id. His focus is on microeconomics, with particular specialization in industrial organization, and he teaches courses on inicroecononiics, regulation, antitrust, and competition policy. I_d. Dr. Willig served as the Chief Econoinist in the Antitrust Division of the United States Departrnent of Justice from 1989 to l99l. lgl_. He also has done research and economic analysis of the railroad industry, including testifying before the STB, and its predecessor, the lCC, about issues affecting the industry. _l_gl_. 64 As for the issue of injury-in-fact, Dr. Willig’s overall conclusion is that assessing injury-in-fact "requires an in-depth individualized inquiry into the circumstances of the particular shipper." Willig Report ‘|| 15. in arriving at this conclusion, Dr. Willig makes six principal points: First, "[t]he fact that shippers paid FSCs [fuel surcharges] is not cornmon evidence of class-wide impact or damages assessment." Willig Report at 13. Second, “[t]he levels of the FSCs paid by shippers provide no common evidence of class-wide impact or damages assessment." _l_q. at 14. Third, "[t]he processes by which FSCs were applied to shipper rates preclude common evidence of class-wide impact or damages assessment." ld. at 16. Fourth, "[a]ll-in rates varied widely and contradict the possibility of com1non evidence showing class-wide impact." ld. at 18. Fifth, "Professor Rausser’s attempts to show that common evidence can establish class-wide impact and assessment of damages fail to support his conclusion." ld_. at 22. Sixth, "[rn]ernbers of the proposed class have conflicting economic interests.” _I,gl_. at 28. 2. Antitrust injury. Although it was not initially apparent from defendants’ papers that they also dispute whether antitrust injury can be established at trial with coinmon evidence, §e_e_ Class Opp. at 50-56 (seemingly equating antitrust injury with injury-in-fact argurnents); §_e_e_ also Oct. 7 Tr. at 172, defendants’ counsel stated at oral argument that defendants do argue that some class members - specitically, captive shippers ~» cannot suffer antitrust injury. §§§ Oct. 7 Tr. at 171-'73. As discussed, antitrust injury is "‘injury of the type the 65 antitrust laws were intended to prevent and that flows from that which makes defendants’ acts unlawful."’ Cordes & Co. Fin. Servs., Inc. v. A.G. Edwards & Sons, Inc., 502 F.3d at 106 (quoting Brunswick Corp. v. Pueblo Bowl-O-Mat, lnc., 429 U.S. at 489). As defendants see it, certain shippers in plaintiffs’ putative class are "captive shippers," also referred to synonymously as "sole served" shippers. Oct. 6 Tr. at 30. Because of various factors, including geographic location, these shippers have "no option but to use a single railroad when it ships out of its place{.]" Oct. 7 'l`r. at 172. Defendants contend that these captive shippers cannot as a matter of law suffer antitrust injury because they have "no reduction in competition" -»- having had no competition in the first place -- "as a result of the alleged wrong." i<_:l_. And defendants argue that identifying such captive shippers requires individualized inquiry. Plaintiffs disagree. Plaintiffs contend that defendants themselves, as well as defendants’ expert, Dr. Willig, admit that captives shippers are subject to competitive pressures, §§§ Oct. 7 Tr. at 304, and that Dr. Rausser’s analysis confirms what defendants themselves have admitted. _Lc“l. at 304-05. The Court first addressees two preliminary legal issues regarding the impact element the number of uninjured class rnembers sufficient to preclude a finding of predominance, and the "presumption" of common impact. The Court then examines the parties’ and the experts’ arguments regarding whether antitrust injury and injury-in-fact are capable of proof at trial through evidence that is common to the class. 66 a. Uniniured Class l\/lernbers The first preliminary legal issue regarding impact involves a dispute between the parties over the number of uninjured class inembers sufficient to preclude a finding of predominance Defendants contend that plaintiffs "n'iust proffer a valid method for proving . . . injury to all or viitually all class members on a simultaneous, class-wide basis[.]" Class Opp. at 26-27 (quotations omitted). Defendants acknowledge that “[s]orne cases have suggested a more relaxed requirement in which inability to show injury as to a few does not defeat class certification where the plaintiffs can show widespread injury to the class." ld. at 27 n.39 (quotations omitted); §§ Oct. '/' Tr. at 258 (defendants’ counsel, acknowledging that "the case law . . . is mixed on the issue of whether every single class member must be injured or whether there's some negligible number"); _s§_e_ also Kottaras v. Whole Foods Mkt., Inc., 2012 WL 259862, at *7-8 (discussing cases addressing number of uninjured class lnembers sufficient to preclude a finding of predoininance). Defendants assert, however, that this "relaxecl requirement" has not been adopted by the D.C. Circuit, and argue that, in any event, plaintiffs have failed to ineet either standard in this case. _S_ee Class Opp. at 27'; Oct. 7 Tr. at 253 'l`he Court concludes that defendants are incorrect about the legal standard for impact. "Class certification is not precluded simply because a class may include persons who have not been injured by the defendants’ conduct." Miins v. Stewart Title Guar. Co., 590 F.Bd 298, 308 (5th Cir. 2009) (citing K.ohen v. Pacific Inv. Mgrnt. Co., 5?’1 F.3d 672, 6'/'7 (”/th Cir. 2009). As the Seventh Circuit stated in Kohen v. Pacific lnvesttnent Manageinent Co.: [A] class will often include persons who have not been injured by the defendant’s conduct; indeed this is almost inevitable because at the outset of the case many of the members of the class may be 67 unknown, or if they are known still the facts bearing on their claims may be unknown Such a possibility or indeed inevitability does not preclude class certiiication{.] Kohen v. Pacific lnv. Mgint. Co., 571 F.3d at 677; se_e Messner v. Northshore Univ. HealthSystem, 669 F.Sd at 823 (citing and quoting Kohen v. Pacific Inv. Mgint. Co., 571 F.3d at 67 7). 'i`hus, the "inability to show injury as to a few does not defeat class certification where the plaintiffs can show widespread injury to the class." Meiier, Inc. v. Warner Chilcott Holdings QQQ, 246 F.R.D. at 310 (quotations omitted). Only when it is apparent that "a great many persons" have not been impacted should a court deny class certification. Kohen v. Pacific lnv. Mgrnt. Co., 571 F.3d at 677'. "There is no precise measure for ‘a great many.’ Such determinations are a matter of degree, and will turn on the facts as they appear from case to case." Messner v. Northshore Univ. HealthSystein, 669 F.3d at 825 (quoting Kohen v. Pacific lnv. Mgmt. Co., 571 F.Sd at 677). b. "Presumption" of Common impact The second preliminary legal issue involves what the partes refer to as a "presuinption" of common impact. Class Mem. at 69; Class Opp. at 27 n.40. "Soine courts have found a presumption of common impact in cases involving allegations of horizontal price-fixing." in re Vitamins Antitrust Litig., 209 F.R.D. at 266 (citing §g;, ln re Master Key Antitrust Litig., 528 F.2d 5, 12, n. ll (2d Cir. 1975); In re Auction Houses Antitrust Litig., 193 F.R.D. 162, 166 (S.D.N.Y. 20()0)). As the Third Circuit stated in Newton v. Merrill Lynch, Pierce, Fenner & Sniith, Inc., "{i]n antitrust class actions, injury may be presumed when it is 68 clear the violation results in harm to the entire class." Newton v. Merrill Lynch, Pierce, Fenner & Smith Inc., 259 F.3d 154, 179 n.2l (3d Cir. 2001). Plaintiffs contend that applying a presumption of coinmon impact in this case would be warranted, because if "Plaintiffs prove that Defendants coordinated their Fuel Surcharge programs in an anticompetitive manner, then it would make basic economic sense to recognize that all Class members, all of whom paid Fuel Surcharges that were either imposed for the first time, or increased by the conspiracy, were impacted by the conspiracy." Class Mein. at 69~70. Plaintiffs, however, make clear that they "do not rest on such a presumption," asserting that they need not do so in view of the evidence in the record in support of their claim of common impact. ld. Although several judges in this district have mentioned this presumption in passing, none actually has applied it. §_§e, e_.g:, Meiier, lnc. v. Warner Chilcott Holdings Co. lIl, 246 F.R.D. at 308 n.l6 (concluding that "[n]o . . . presumption is required . . . because [p]laintiffs have established that common proof will predominate over individual issues"). And as the Third Circuit more recently stated in in re Hydrogen Peroxide Antitrust Litig.: "Applying a presumption of impact based solely on an unadorned allegation of price-fixing would appear to conflict with the 2003 amendments to Rule 23, which emphasize the need for a careful, fact-based approach, informed, if necessary, by discovcry." in re Hydrogen Peroxide Antitrust I_._it_ig_., 552 F.3d at 326. 'l`o the extent that any such presumption of common impact remains valid law, sic i_d_. at 327 (stating that district court, on remand, could consider whether presumption of common impact "is compatible with the record of th[e] case"), it appears to be 69 some sort of presumption-plus, requiring "some additional amount of einpirical evidence." American Seed Co., lnc. v. Monsanto Co., 271 Fed. App’x 138, 141 (3d Cir. 2008). The Court agrees with the reasoning set forth by the Third Circuit in _Ip__r§ Hydrogcn Peroxide Antitrust Litig. and concludes that applying a presumption of impact based on an unadorned allegation of price fixing appears inconsistent with the rigorous analysis that must be performed in examining whether the requirements of Rule 23(b)(3) have been met. And whatever remains of any such presumption or presumption-plus under the law, the Court concludes that no presumption is required in this case, as plaintiffs themselves make clear that they do not rely on it. Nor do they need to. c. Antitrust Injug in order to establish antitrust injury, the legal component of the impact element, at trial, plaintiffs "must prove that the defendants engaged in an anti-competitive manipulation of the markets." In re EPDM Antitrust Litig., 256 F.R.D. at 87. in examining this legal component at the class certification stage, the Second Circuit held in Cordes & Co. Financial Services, lnc. v. A. G. Edwards & Sons, lnc. that the plaintiffs successfully established that antitrust injury was common to the class and predominated over individual questions because the plaintiffs alleged only one type of injury in the complaint "overcharges paid to a horizontal price-fixing conspiracy." Cordes & Co. Fin. Servs., lnc. v. A.G. Edwards & Sons, lnc., 502 F.3d at 107. As the Second Circuit stated in _Q_r_gr_t§:§: "Because each class member allegedly suffered the same type of injury, the legal question of whether such an injury is ‘of the type the antitrust laws were intended to prevent and that flows from that which makes defendants’ acts unlawful,’ . . . is a 70 common one." _I_<_l_. (quoting Brunswicl< v. Pueblo Bowl-O-Mat, Inc., 429 U.S. at 489). As in Cordes, the Court concludes that plaintiffs have satisfied the first part of the impact element by showing that the legal question of antitrust injury is common to the class and predominates over individual issues. Plaintiffs have alleged only one type of injury in their second ainended consolidated complaint: that defendants’ price fixing conspiracy imposed supra-co1npetitive total price increases on the putative class, in violation of Section 1 of the Sherman Act. S_e§ 2d Ain. Compl. jlj] l-2; Class Mem. at 1. Plaintiffs contend that the type of supra-competitive overcharges allegedly imposed in this case "clearly constitute antitrust injury." Class Mem. at 65 n.22l. Defendants disagree as to a subset of putative class members, arguing that so-called captive shippers cannot suffer antitrust injury. As defendants’ counsel described it at oral argument, antitrust injury is the injury that flows from the harm that the antitrust laws are intended to prevent, and the antitrust laws are intended to prevent only a reduction in competition. §=._e_ Oct. 7 Tr. at 172-73. Consequently, if there is "no competition in the first instance for a customer’s business, that customer cannot suffer antitrust injury." _Igl. at 173. Defendants and Dr. Willig contend that shippers served by only one railroad do not benefit from rail-to-rail competition, and, as a result, the railroad serving such a shipper would be expected to attempt to extract the maximum possible rate given the shipper’s non-rail alternatives and the value the shipper derives from rail service. A conspiracy among railroads does not enable the serving railroad to extract more than the rnaxirnuin rates from such a shipper For shippers served by only one railroad, any attempt by the sewing railroad to impose an FSC that is not desired by that shipper would be expected to require that the railroad inake a concession with respect to base rate or another dimension of contract. 71 Willig Report '1[ 132. Dr. Willig contends that any claim that captive shippers enjoy competition "is contradicted by the well-recognized fact that ‘captive’ shippers experience higher prices than shippers that face head-to-head rail competition." _l_d_. 1| l35. The antitrust laws were enacted for "‘the protection of competition[.]"’ Ai_i_c_l_r§ Pharnis., lnc. v. Biovail Corp. int’l, 256 F.3d at 812 (quoting Brunswick Corp. v. Pueblo Bowl-O-Mat lnc., 429 U.S. at 488) (emphasis in original). Defendants therefore are correct that "where there {is] no competition, there [is] no antitrust injury." City of Pittsburgh v. West Penn Power Conip., 147 F.3d 256, 266-67 (3d Cir. l998). in other words, "[w]ithout demonstrating that there was competition, a plaintiff cannot show that the defendants’ actions have had or will have anticompetitive effects." id_. (citing Continental Cablevision of Ohio, lnc. v. American Elec. Power Co., 715 F.2d lll5, 1119-20 (6th Cir. 1983); §§ also in re Tobacco/Goveininental Health Care Costs Litig., 83 i~`. Supp. 2d l25, 134-35 (D.D.C. l999) ("The antitrust laws were not intended to prevent losses that result from increased competition but those resulting from activity that may tend to lessen competition. . . . The reason an antitrust plaintiff is required to plead antitrust injury is to assure that a plaintiff can recover only if the loss stems from a coinpetition-reducz`rzg aspect or effect of the defendant’s behavior.") (quotations omitted) (alteration and emphasis in original). The Court, however, disagrees with defendants and Dr. Willig that captive shippers are not subject to competitive forces -- a claim that is contradicted by the statements of defendants’ own executives NS’ chief executive officer, Charles W. Moorman, testified before Congress in 2007 that even captive shippers are subject to "competitive constraints [that] are real," and he expressly acknowledged that "even where there is only one railroad serving a 72 facility, there are market factors at play." Corrected HD Ex. 36, Written Stateinent of Charles W. l\/Ioonnan, at 16, Sept. 20, 2007. Similarly, UP’s chief executive officer, James Young, agreed that railroads place "competitive constraints" on each other, even in the case of captive shippers. HD Ex. 66, Young Dep. at 201. And CSX has acknowledged in internal documents that "[s]tudies have shown that, in aggregate, captive shippers don’t pay higher prices than non-captive shippers," and that "CSX[] sets prices based on all competitive factors." HD Ex. 37 , CSX Talking Points Response to Escalation Resource - Fuel Surcharge Alert, at CSXFSC000l53 187. That captive shippers enjoy competition is further reflected by the experience of one of the named plaintiffs in this case before and during the class period, U.S. Magnesium has an operating facility outside of Salt Lake City, Utah. As plaintiffs’ counsel stated at oral argument, that plant is truly captive w "[t]here is . . . a single rail line coming up to the plant, which is owned by [UP}." Oct. 6 Tr. at 92-93. in December 2002, before the class period, U.S. l\/iagnesium riegot.iazed out of the application of a fuel surcharge. ._S__e_e_ RD Ex. l0, at USl\/l005647 (UP proposing to U.S. Magnesium a 4 percent increase on all rates and application of a fuel surcharge, but ultimately agreeing to a 4 percent across the board increase without a fuel surcharge). But one year later, during the period when plaintiffs say that defendants were conspiring to impose fuel surcharges uniformly as to all shippers, the application of a fuel surcharge was "lnandate[d] by UP management[.]” RD Ex. 72, at USM005663. l\/ioreover, defendants’ executives expressly have denied in their depositions taken in this case that they would have tried to impose more aggressive programs on captive shippers than they were able to impose on non-captive shippers. BNSF’s chief executive ofticer, Matthew 73 K. Rose, stated that BNSF had never considered having a higher or more onerous fuel surcharge for captive shippers, and that such an approach would "violate [BNSF] principle." HD Ex. 72, Rose Dep. at 232. UP’s chief financial oflicer, Robert Knight, Jr., acknowledged that he was unaware of any discussions on the topic of having separate fuel surcharge programs for captive shippers. HD Ex. 70, Knight Dep. at 64. 'fhese statements are consistent with Dr. Rausser’s analysis and conclusion, which the Court finds persuasive, that defendants’ transaction data show that "so-called captive shippers paid the same Fuel Surcharge as others” during the class period. 2d Rausser Report at 23. The Court therefore finds by a preponderance of the evidence that railroads are affected by competitive constraints that apply to both captive and non-captive shippers, and that plaintiffs have satisfied the first part of the impact element for all putative class inembers, including captive shippers, by showing that the legal question of antitrust injury is common to the class and predominates over individual issues. §_ee Cordes & Co. Fin. Servs., Inc. v. A.G. Edwards & Sons Inc., 502 F.3d at 107.'3 '3 The Seventh Circuit’s decision in Messner v. Northshore University HealthSystem suggests that defendants’ argument regarding captive shippers and antitrust injury is more appropriately categorized as an argument that "the class for which certification is requested is fatally overbroad because it contains members who could not have been harined{.]" Messner v. Northshore Univ. HealthSvstem, 669 F.3d at 824. As the court in Messner explained: "[I]f a proposed class consists largely (or entirely, for that inatter) of members who ore ultimately shown to have sujj’ered no horm, that may not mean that the class was improperly certified but only that the class failed to meet its burden of proof on the 1nerits. . . . if, however, a class is defined so broadly as to include a great number of members whofor‘ sonia rcasorz could not have been harrneo' by the defendant’s allegedly unlawful conduct, the class is defined too broadly to permit certification." i_ci. (emphasis added). As the Court has found, however, plaintiffs have shown by a preponderance of the evidence that railroads are affected by competitive constraints applying to both captive and non-captive shippers. Thus, the Court concludes that the class is not defined so broadly as to include a great number of inembers who "co.uld not have been harmed" by defendants’ allegedly unlawful conduct. ic_i_. 74 d. Inju§y~in-Fact The Court now addresses whether injury-in-fact is capable of proof at trial with evidence coinmon to the class rather than individual to its members. _S_e_e ln re Hydrogen Peroxide Antitrust Litig., 552 F.3d at 311-12. The Court finds by a preponderance of the evidence that it is, "it is a basic tenet of antitrust law that a cause of action will not lie if the plaintiff has not been harmed.” Warren Gen. Hosp. v. Amgen inc., 643 F.3d 77, 92 (3d Cir. 2011). Thus, in order to prevail at trial on their Sherman Act claim plaintiffs must prove not only an antitrust violation - here, that defendants’ conspired on their fuel surcharge programs -»- but also a "causal link between the violation and an injury to . . . business or property." federal Prescription Serv., lnc. v. American Pharm. Ass’n, 663 F.2d 253, 268 (D.C. Cir. 1981); _sp_e Tavlor Publ’g Co. v. .lostens, inc., 216 F.3d 465, 485 (5th Cir. 2000) ("[T]he fact of damages . . . means that the antitrust violation must cause injury to the antitrust plaintiff.") (quotations omitted); §§ also Hecht v. Pro-Football, lnc., 570 F.2d 982, 987 (D.C. Cir. 1977) ("{T]he plaintiff must show both an fnjury-z`ri-jfact to his business or property and a causal connection between that injury and the defendant’s allegedly illegal acts.") (emphasis in original) (quotations o1nitted). Plaintiffs "need not exhaust all possible alternative sources of injury in fulfilling [their] burden of proving compensable injury under" the antitrust laws, but they must show that the antitrust violation was a "material cause of the injury[.]" Zenith Radio Coip. v. i-iazeltine Research, inc., 395 U.S. 100, 114 n.9 (1969). if plaintiffs would have suffered the same injury absent a conspiracy, then plaintiffs will fail on the merits of their claim. _S_e_e F ederal Prescription Serv., lnc. v. Ainerican 75 Pharm. Ass’n, 663 F.2d at 268. Put another way, if the same alleged injury would have been caused by independent, non-conspiratorial forces, then no causal link exists between the alleged antitrust violation and the injury. And if individualized inquiry is necessary to make such a determination on causation, then plaintiffs will have failed to show that common questions predominate as to injury-in-fact. § in re New Motor Vehicles Canadian Exp. Antitrust Litig., 522 F.3d at 25 (“Plaintiffs cannot make their case without common proof of causation{.]"); §_e_e_ also Kottaras v. Whole Foods Mkt., Inc., 2012 WL 259862, at *7. This causation question f whether an antitrust violation was a material cause of an injury - commonly is assessed by reference to what the parties and their experts refer to as the but-for world. §”_e_e_ In re EPDM Antitrust Litig., 256 F.R.D. at 88 ("[G]enerally speaking, antitrust injury-in-fact and damages are often determined by comparing the ‘but-for’ price m the price a customer would have paid in the absence of the conspiracy -- and the actual price paid."). This hypothetical construct is a world that is "free of the restraints and conduct alleged to be anticompetitive." Blades v. Monsanto Co., 400 F.3d 562, 569 (8th Cir. 2005); §;e__c_: Cordes & Co. Fin. Servs., lnc. v. A.G. Edwards & Sons, lnc., 502 F.3d at 107; Concord Boat Corp. v. Brunswick Co§p., 207 F.3d 1039, 1055 (8th Cir. 2000). One way of showing that common questions predominate on the issue of injury-in-fa.ct l is to show that there is a common m.ethod for proving that the class plaintiffs paid higher actual prices than in the but-for world, such as using an economic regression model incorporating a variety of factors to demonstrate that a conspiracy variable was at work during the class period, raising prices above the but-for level for all plaintiffs 76 In re EPDM Antitrust Litig., 256 F.R.D. at 88. And this precisely is what plaintiffs have attempted to do through their expert, Dr. Rausser. Comparing but-for prices with actual transaction prices by regression analysis, however, is "not the only way for plaintiffs to succeed in a motion for class certification." l_n_;e EPDM Antitrust Litig., 256 F.R.D. at 88 (emphasis in original). Other accepted types of evidence for establishing class~wide injury-in-fact include: evidence of lock-step increases of national price lists, s_ee_ i_d.; proof that defendants conspired to maintain an inflated base price from which all negotiations began, _sj§:me _i~d. at 89; and evidence of structural factors that make an industry susceptible to successful collusion. _S_ee id at 91-93; §_e_e a_ls_q Behrend v. Comcast _CQL, 655 F.3d at 199. Ultimately, the question is whether plaintiffs have shown by a preponderance of the evidence _ through regressions, structural industry factors, or any other persuasive means w that "rnethods of coinmon proof exist to show class-wide impact[.]" _I_n_re EPDM Antitrust Litig., 256 F.R.D. at 88; s_ce_e in re New Motor Vehicles Canadian Exp. Antitrust _l;i_t_ig;, 522 F.3d at 25-26. The alleged antitrust violation in this case is a conspiratorial agreement to impose supra-competitive fuel surcharges -~ a component of the total price of a freight shipment m as a percentage multiplier of the base rate of transportation as a means to impose supra-conipetitive price increases on the putative class. §_e__e_ Class Mem. at 1; Am. Compl. 1§1| l-2. Plaintiffs do not allege that defendants conspired to fix each base rate separately, §_e__e lst Rausser Dep. at 98 ("Q. . . . There is no agreement to raise the base; right‘? A. Yes. Q. So all of the injury comes from the fuei surcharge; right? A. Ultiiiiateiy, yes."), which, Dr. Rausser explains, "vvould have been extremely compiex, highly costly and effectively unrnanageable." lst Rausser Rep. at 52 n.l 18. 77 Because the aileged antitrust violation involves only a component of the total price, at trial plaintiffs will be required to prove in fact (l) that they paid a tiiel surcharge because of the aileged conspiracy and (2) that, as a result, they paid more for shipping than they otherwise would have paid. And in order to prevail at the class certification stage, plaintiffs now niust show by a preponderance of the evidence that common proof can be used to answer the questions (l) whether class inernbers paid a fuel surcharge because of the alieged conspiracy; and, if so, {2) whether payment of that fuel surcharge caused class members to pay more for shipping than they otherwise would have paid. Plaintiffs contend that they have met their burden. They assert that they will prove injury-in-fact at trial with public information, defendants’ own documents, and witness testimony, all of which will be common to the class. _S;e_e Class Mem. at 7'0-'5"1. Plaintiffs further assert that Dr. Rausser’s expert report confirms through economic regression analysis that injury~in-fact is capable of common proof at trial. §g§ _i_d_. at 7 l-75. Defendants and Dr. Willig disagree that common evidence can be used to establish injury-in-fact at trial. §ee Class Opp. at 28-56. As for Dr. Rausser’s economic regressions, defendants and Dr. Willig argue that Dr. Rausser’s analysis is "t`atally flawed.” § at 50. Defendants do not “quibble with the notion . . . that regression analysis can in many cases provide a basis for certifying a class." Oct. 7 Tr. at 263. But defendants maintain that Dr. Rausser’s regressions and analysis suffer front methodological failures that render his conclusions unreliable, _s¢_:_e Class Opp. at 62-72, ultimately invalidating his report altogether. Q. at 72. 78 'l`he Court concludes that plaintiffs have satisfied their burden at this stage. lt finds by a preponderance of the evidence that injury-in-fact is capable of proof at trial through evidence that is common to the class rather than individual to its members. i. Payment of an allegedly conspiratorial fuel surcharge Defendants argue that individualized analysis is required to determine whether class members would have paid a fuel surcharge but for the conspiracy. §§ Class Opp. at 28. As defendants see it, plaintiffs have failed to offer any methodology by which they can show with coinmon proof that class members would not have paid a fuel surcharge in the but-for world w that is, the non-conspiratorial world. _S_e§ § First, defendants assert that they had considerable ability and incentive to adopt fuel surcharges entirely independent of any conspiracy. _S§g Class Opp. at 30. In support of this claim, defendants point to the purported trend toward increased use of fuel surcharges before the alleged conspiracy, and then contend that it is implausible that this trend would have stopped in the but-for world. _S_ee_ _i_d_. at 30-31. Specii`ically, defendants assert that fuel surcharges were "widely used" before the start of the conspiracy, with nearly 60 percent of shippers paying a rate-based fuel surcharge as of June 2003, i_d. at 31 (citing Willig Report ‘|| 77); that there was "a strong trend toward increasing use of fuel surcharges before the start of the alleged conspiracy," _i_r_i_. at 32, and that it is "iinplausible to suggest that this trend would have come to a screeching halt in mid-2003," i_d. at 33; and that the use of fuel surcharges did not accelerate after the start of the alleged conspiracy -»- "on the contrary . . . , the growth rate actually slowed after July 2003 for every defendant." §. at 34 (emphasis in original). 79 Dr. Willig points out that there are legitiniate economic rationales for the use of l fuel surcharges because they can enhance economic efficiency §__e_g Willig Report 111 65-68. As Dr. Willig explains: The use of FSCs in many industries expanded in the early 2000s in response to increases in both the levels and the volatility of fuel prices, Over the alleged conspiracy period, fuel costs became an increasingly large component of rail costs. . . . FSCs were adopted in the rail industry due in part to dissatisfaction with the RCAF index, which lags behind changes in fuel prices, resulting in delays in cost recovery when fuel prices are rising. Willig Report {l$l 65-66. 'l`hus, in view of the purported evidence showing a trend toward the increasing use of fuel surcharges and the legitimate rationales for their use, defendants conclude that there is no basis upon which the Court can conclude "that all or most of the members of the purported class would not have paid fuel surcharges absent the alleged conspiracy." i_d_. at 35. Second, defendants argue that plaintiffs face an even higher hurdle for a large group of shippers in plaintiffs’ putative class, 55 to 68 percent of the class, that were already paying fuel surcharges before July 2003 _ a group referred to by the parties as legacy shippers. §e_e_ Class Opp. at 35. As defendants note, plaintiffs have excluded some legacy shippers from the class definition. §_e_e i_d. Spccifically, plaintiffs have excluded from their putative class those shippers that paid a fuel surcharge during the conspiracy period "solely pursuant to a railroad-sliipper contract that was (i) entered into before July l, 2003, and (ii) provided for a stand-alone Fuel Surcharge to be paid under a predetermined formula specifically set forth in the contract." Class Mot. at l. if however, a legacy shipper entered into a new contract during the class period that included a fuel surcharge, that shipper then is included in plaintiffs’ class 80 because it would not have paid a fuel surcharge "solely pursuant to a railroad-shipper contract that was . . . entered into before July 1, 2003[.]" Class Mot. at l (emphasis added); §§ Class Opp. at 35-36. And defendants contend that this "narrow legacy exclusion," Class Opp. at 35, presents a significant causation problem illustrated by the following example: Consider a shipper that entered into a contract running from january 2002 through December 2003 that contained a fuel surcharge. if such a shipper entered into a new contract in Januaiy 2004 that also contained a fuel surcharge, it would fall within Plaintiffs’ class definition because the fuel surcharge was not "solely" in the pre-conspiracy contract. But, proof of causation for such a shipper is problematic at best. The fact that the shipper had a fuel surcharge when Defendants were concededly acting independently makes it extremely likely that a fuel surcharge would have been included in its january 2004 contract, regardless of any alleged conspiracy to expand fuel surcharge coverage. Certainly one cannot presume that all such shippers would have avoided fuel surcharges thereafter. _ld. at 36. Third, defendants argue that any attempt to distinguish class members that had a fuel surcharge only because of the alleged conspiracy from those that would have been subject to one anyway necessarily would require individualized analysis. _Sie Class Opp. at 36-39. According to defendants, many factors influence not only whether a customer would pay a fuel surcharge in the but-for world but also the level of that surcharge. lll. at 37. Defendants contend that these factors include: customers served by only one railroad (captive shippers); customer history of purchasing rail freight; existence of capacity constraints; customers whose primary freight alternative was truck; and customer receptivity to fuel surcharges. _S_e_e id at 37-39. Defendants contend that these factors show that individualized analysis is required to determine injuiy-in-fact at trial. gap i_d. at 36-37. 81 Plaintiffs disagree with defendants and make three principal points in response. First, plaintiffs argue that defendants have incorrectly lumped fuel surcharges before the conspiracy with the unifonn, standardized, and supra-competitive fuel surcharges imposed during the conspiracy. According to plaintiffs, the fuel surcharges imposed during the conspiracy period were "different both in design and application from those that caine before." Class Reply at 7. Second, plaintiffs argue that evidence common to the class contradicts defendants’ claim that the same fuel surcharges imposed during the conspiracy would have been imposed in the but-for world. And third, relying on the economic regression analysis conducted by Dr. Rausser, plaintiffs contend that evidence common to the class refutes defendants’ claim that any individualized factors predoniinate. § Class Reply at 6-l6. As for plaintiffs’ first point, they contend that "[in]ost of defendants’ arguments and Dr. Willig’s analysis are built on a faulty assumption: that the FSCs used by Defendants before and during the conspiracy were the same." Class Reply at '7. Plaintiffs assert, however, that the allegedly conspiratorial fuel surcharges put in place in the spring of 2003 were different both in design and application from those that came before. . . . [T]hese new FSCs (i) got Defendants in lockstep in calculating the percentage based on fuel indexes; (ii) used a trigger equal to about 823 per barrel, rather than the higher 828 per barrel (or higher) that several Defendants had previously used; and (iii) adjusted the FSC based on the 30-day average fuel price, rather than, as in several Defendants’ earlier programs, only when the trigger was exceeded for 30 (or more) consecutive days. Class Reply at 7. For this argument, plaintiffs rely on the testimony of defendants’ own employees who repeatedly have admitted in depositions that the new fuel surcharges imposed during the class period were "not the same as, were more aggressive than, and definitely yielded 82 more revenue" than fuel surcharge programs applied before the alleged conspiracy l_d. at 7 & n.l6 (quotations oinitted). Moreover, plaintiffs say that these new, standardized, more aggressive fuel surcharges were uniformly applied, with the express goal of 100 percent coverage. _l_d_. at l; § id_. at 9-l0. ln contrast, fuel surcharge programs applied before the conspiracy in some contracts were only "theoretically billable, in that they often were not triggered or applied, and when they were, they were small." _l_d_. at 8 (quotations oinitted). Regarding their second point, plaintiffs dispute defendants’ view of the but-for world, arguing that it fails to acknowledge actual facts, established with evidence common to the class, that defendants needed to conspire to surmount obstacles to widespread application of uncoordinated fuel surcharges. As plaintiffs see it, before the conspiracy, defendants were frustrated by the structural decline in rail freight rates and their inability to raise prices due to "destructive pricing for rail share." Class Reply at 10 (quotations omitted). According to plaintiffs, defendants were unable to use fuel surcharges as an effective revenue generator because of competition ainong the defendants, customer resistance, and the frequent use of the RCAF index. I_d. Consequently, plaintiffs argue that defendants’ experience with “theoretical and insignificant FSCs before the Class Period cannot be extrapolated to the Class Period beoause, among other reasons, increased customer resistance would be expected as the FSCs were triggered with rising fuel prices, and as Defendants sought to lower the trigger thresholds and implement more aggressive FSC programs." Class Reply at ll-l2 (quotations oniitted). Regarding their third point, plaintiffs contend that Dr. Rausser’s regressions -~ now based on an analysis of l00 percent of defendants’ transaction data, sic 2d Rausser Report at l2; Class Reply at 38 ~ refute defendants’ and Dr. Willig’s assertion that individualized 83 factors predominate. § Class Reply at 12. According to plaintiffs, Dr. Rausser has used economic analysis to show that workable formulas, common to the putative class, are available to "prove the conspiracy’s impact on the class - a ‘structural break in the relationship between fuel prices and freight rates,’ a surge in rates attributable to the conspiracy, and significant overcharges in comparison to prices that would have prevailed absent the conspiracy[.]" Q. at l (quoting lst Rausser Report at 120, 122-23). As plaintiffs describe it, Dr. Rausser’s analysis confirms that overall freight prices are based on seven factors that arc common to all shipments, including, among other factors, shipment weight, distance, route, and commodity type; and that these seven factors can be measured using defendants’ transaction data and can be used in a common analysis to identify and quantify the injury experienced by the class. lst Rausser Report at '7. Dr. Rausser’s regression analysis takes into account the factors that influenced defendants’ prices during the class period compared with benchmark prices during the three preceding years - a time period in which Dr. Rausser concludes that defendants "acted as an interdependent oligopoly unaffected by the type of collusion that determined prices during the Class Period." lst Rausser Report at l l3. Upon an analysis of defendants’ transaction data, Dr. Rausser identified a "structural break in the relationship between freight rates and fuel prices around 2003, which is consistent with a conspiracy using Fuel Surcharges to raise freight rates.” 2d Rausser Report at 92. In other words, Dr. Rausser’s analysis shows that, before the alleged conspiracy, “there was a relationship between fuel costs and overall prices that was dramatically changed once the [alleged] conspiracy went into effect." Oct. 6 Tr. at 139; §_r:_e i_d. (stating that, before the alleged conspiracy, "if fuel prices went up by a certain amount, it would have a certain effect . . . on rail freight prices 84 overall; and after the [alleged] conspiracy, if fuel prices went up, it had a much bigger effect on the overall price"). Plaintiffs therefore contend that Dr. Rausser’s analysis shows that members of the class paid artificially higher prices as a result of the conspiracy and were injured-in-fact by the antitrust violation. §e_e_ Class Mem. at 47. The Court agrees with plaintiffs and finds that they have shown by a preponderance of the evidence that common evidence can be used at trial to answer the question whether class members paid the allegedly conspiratorial fuel surcharges because of the alleged conspiracy: l. Fuel surcharges during the class period - aggressive storidar'dized, and aniform. The Court is unpersuaded by defendants’ and Dr. Willig’s atteinpt to link fuel surcharges that were in place before the alleged conspiracy to those applied during the alleged conspiracy. Defendants place significant weight on their conclusion that their transaction data show that "alinost 60% of Defendants’ customers, including all eight of the named Plaintiffs, paid rate-based fuel surcharges before the conspiracy began." Class Opp. at 2 (emphasis in original). And, according to defendants, Dr. Rausser’s admission during his deposition that he would have expected each defendant to impose fuel surcharges as broadly as possible even absent the conspiracy is particularly dairining. § § (citing lst Rausser Dep. at 281). But as plaintiffs and their expert iiial<.e clear, their antitrust claim in this case is not a conspiracy to impose just atty fuel surcharge; rather, plaintiffs claim that defendants agreed to increase total prices "by widespread application and enforcement of coordinated, and aggressive, fuel surcharges.” Pls. Wal-Mart Reply Brief at 7 n.l l; ge_g §._lgq lst Rausser Dep. at 94; 2d Rausser Dep. ar 119»21. 85 The Court finds by a preponderance of the evidence that the fuel surcharge programs applied before the class period were nothing like the widespread and uniform application of standardized fuel surcharges during the class period, Before the alleged conspiracy, defendants’ differentiated fuel surcharges were subject to competition and negotiation with shippers, were less aggressive, and were applied only sporadically. Furthennore, these pre-class period fuel surcharges were only "theoi'etically billable." l-lD Ex. 65, Glennon Dep. at 26 (manager of NS pricing systems (now retired) acknowledging that before the class period "the fuel surcharge was theoretically billable, so l would say that . . . customers might not resist it as rnuch").

'i'l, McNulty Dep. at ll8-l9 (CSX director of marketing, agricultural products discussing "fairly minimal" fuel surchargers in 200l and 2002). The fuel surcharges that defendants put in place in the spring of 2003 were of a different breed. §__§c_:_ Class Reply at 7 (fuel surcharges were different "both in design and application from those that came before"). The evidence shows that defendants employed these fuel surcharges in lockstep, lowered the trigger price for the imposition of the fuel surcharge, and adjusted the fuel surcharge based on the 30-day average fuel price rather than only when the trigger was exceeded for 30 (or more) consecutive days. § lst Rausser Report at 54-60. Defendants’ own executives admitted that the new fuel surcharge programs applied by the defendants during the class period were different - that is, they were more aggressive and yielded more revenue than earlier programs for exainple, UP’s chief executive officer, james Young, testified that compared to the pre-2003 time period, the impact of fuel surcharges on customers . . . was greater in ’03, it was greater in ’04, it was greater in ’05 because, again, the percent of recovery.

But such a program - that is, one "that increases all rates by a set percentage" ~M "stands virtually no prospect of reflecting the actual increase in fuel costs for handling the particular traffic to which the surcharge is applied." _l_d_. at *4; ge gl_so_ lst Rausser Report at 50 ("{A]dding a percentage fuel surcharge on top of line-haul rates or base rates is by its very nature a general price increase."). Captive shippers. Defendants’ and Dr. Willig’s argument regarding captive shippers and injuiy-in~fact is essentially identical to the one made during oral argument regarding antitrust injury. §ee §§ at 65~66, 71-72. Defendants say that customers served by only one railroad m referred to by the parties as either "captive" or "sole served" shippers - "inight have ” As for use of the RCAF~A mechanism of recovery, BNSF price and fuel escalation guidelines stated: "RCAF-A is absolutely unacceptable."

Class Opp. at 37."‘ Moreover, as defendants contend, such shippers "do not benefit from rail competition in the first place" and therefore "cannot be injured by an alleged conspiracy among railroads." Defs. Supp. Brief at 18 11.10. Thus, defendants argue that the alleged conspiracy on fuel surcharges would not be expected to injure such captive shippers, Class Opp. at 37, and that such shippers m- of which they are "many . . . , although the number cannot be determined with precision," Willig Report at 75 a can be identified only with individualized inquiry. _S__qe Willig Report 1[1[ 139-43. And so defendants argue that the existence of such shippers in plaintiffs’ putative class precludes a finding of predominance. The Court disagrees with defendants As the Court already has concluded, plaintiffs have shown that captive shippers are subject to competitive forces; that defendants’ executives expressly have denied that they would have tried to impose more aggressive programs on captive shippers than they were able to impose on non-captive shippers; and that defendants uniformly imposed their standard fuel surcharges during the class period without regard for whether the shipper was captive or had access to alternative modes of transportation §§ §Mu~p»rg at ?2-?4; §§ _c;g;, HD Ex. 79, Garin Dep. at 111-14, 117-18, 120»21, 126-29; HD Ex. 77, i_,istwak Dep. at '74~76, 93~101; §e_e gjsg HD Ex. 153, Draper Dep. at 322 (agreeing that UP "adopted a standard surcharge program that it intended to be coinmon across its customers," and explaining that "the difficulty of doing it -on a customer~by-custorner basis is one of the reasons it ’8 As defendants explain, the term "captive" is used in two different Ways: "ln some cases, it is applied to a shipper that is served by only one railroad although that shipper has viable transportation options available through trucks and/or barges. Other tirnes, it is applied to a shipper that claims that it has no viable transport aiternatives to the raiiroad that serves it." Defs. Supp. Briefat 18 n.l0. 98 was done on a global basis"). Plaintiffs have shown by a preponderance of the evidence that defendants applied the allegedly conspiratorial fuel surcharges without discrimination. Thus, the captive-shipper factor does not preclude a finding that injury-in-fact is capable of common proof at trial. Cuslonter history ofpur'chosz'ng rac'lfrelz`ght; existence ofcapacity corrstrairzts; customers whose prz'rna)jyj”rreigfrt alternative was lruclc. Defendants argue that roughly one~third of the shippers in the putative class first purchased rail freight after July 2003, and these shippers therefore "have no pre-conspiracy history on which to assess their likelihood of paying fuel surcharges absent collusion." Class Opp. at 38. Other shippers "have a long~standing history of rail freight purchases from Defendants, which could inform what the negotiation would have looked like, and whether it would have resulted in an assessment of a fuel surcharge, absent the conspiracy." Q. Defendants contend that these varying histories require individualized analysis that preclude a finding of predominance. Next, defendants argue that certain shippers faced capacity constraints, and such shippers would be more likely to pay a fuel surcharge in the but-for world, even with rail-to-rail coinpetition. §ge Class Opp. at 38. And defendants then point to customers whose primary freight alternative was tiuck. §e_§ id According to defendants, these customers "would be likely to accept a rail fuel surcharge because trucking companies charged a fuel surcharges." Q. As defendants see it, "[c]ustomers already paying fuel surcharges to competing transportation alternatives would be unlikely to reject the idea of fuel surcharges by railroads." I_d. The Court disagrees with defendants that any of these factors preclude a finding that injury~iri-fact can be established at trial with common evidence. Evidence common to the 99 class shows that defendants intended to apply the new standard fuel surcharges to all of their freight shipments - regardless of prior freight purchasing history or any other factor. To prevail on the merits of their claim at trial, plaintiffs "need not exhaust all possible alternative sources of injury in fulfilling [their] burden of proving compensable injury under" the antitrust laws, §e_n@ Radio Corp. v. Hazeltine Research, lnc., 395 U.S. at 114 n.9. Rather, they must show only that the antitrust violation was a "material cause of the injury[.]" E. And at the class certification stage, plaintiffs must show by a preponderance of the evidence that this is capable of common proof They have satisfied their burden at this stage: plaintiffs have established by a preponderance of the evidence that each defendant enforced policies ensuring across-the~board, uniform application of their new fuel surcharge program, Custorrzer receptivity lofuel surcharges. Defendants argue that some shippers were "more amenable to fuel surcharges, and thus would have been more likely to agree to a fuel surcharge even with competition among railroads." Class Opp. at 39. Defendants point out that several sophisticated clients ~“~» ~»- themselves proposed to pay a rate-based fuel surcharge. §p_e i_d. According to defendants, _, for example, “proposed a rate~based fuel surcharge when its UP contract first came up for renewal after July 2003." _ld_. - "volunteered to pay BNSF and NS a fuel surcharge even though its contracts with those carriers did not require it." i_d_. - "acknowledged the need for a fuel surcharge in its contracts with CSX[] because of the volatility of fuel prices." _I_c_l. , both BNSF customers, "were willing to pay a fuel surcharge so long as their own formulas were used." E. According to defendants, these examples provide further support for their claim that individualized analysis is necessary in order to determine what l00 caused shippers to pay a fuel surcharge and whether they would have paid a fuel surcharge in the but-for world. § § The Court disagrees with defendants That some shippers may have been willing to pay a fuel surcharge is not surprising lndeed, the STB noted in its 2007 decision that several railroads had introduced evidence that "n'rany of their customers favor the continued use of a fuel surcharge program that is tied to the base rate." Rail Fuel Surcharges, 2007 WL 201205, at *6 n.34. As the STB stated: "Given that such a program shifts greater responsibility for fuel recovery to shippers with higher rates, it is not surprising that a subset of customers (presuinably those with lower base rates) favor retaining a percentage-0f-the-base~rate approach." l”d,. But the claim in this case is not a conspiracy to impose just any fuel surcharge; rather, plaintiffs claim that defendant conspired to increase total prices "by widespread application and enforcement of coora'inatea', and aggressive fuel surcharges." Pls. Wal-Mar'l; Reply Brief at 7 n. ll (emphasis added); §§ a_tls_g lst Rausser Dep. at 94-95. 'l`hus, defendants’ assertion that, for example, were "willing to pay a fuel surcharge so long as their own fornzulas were used," Class Opp. at 39 (emphasis added), does not discredit plaintiffs’ conclusion that injury-in-fact from widespread, aggressive, standardized, and uniform fuel surcharges is capable of common proof at trial. ii. Component of the total price of shipping A fuel surcharge is an add-on to the base rate for freight transportation The total rail freight price for a shipping customer w the all-in rate -- consists of the base rate and any l0l percentage fuel surcharge applied to the base rate. Willig Report ll 18; g_e_§ Class Opp. at 3; lst Rausser Report at 62. The base rate includes fixed cost (or overhead) elements, such as the cost of organizing a particular shipment[,] . . . . the large fixed costs of building and maintaining track, bridges, and other structures to achieve long-run sustainability[,] . . . . [and] the railroad’s markup of price over costs, i.e., the profitability element of pricing lst Rausser Report at 62. As discussed, plaintiffs do not allege that defendants conspired to fix each base rate separately. §e§ lst Rausser Dep. at 98; _se_c_e ja_l§_q lst Rausser Report at 52 n. 1 18. Rather, plaintiffs allege that defendants imposed "an across-the-board artificially high and uniform fuel surcharge" as a percentage multiplier of the base rate, thereby permitting defendants "to raise total freight prices widely by a given percentage." , 587 F. Supp. 2d at 30; § g lst Rausser Report at 50 ("{A]dding a percentage fuel surcharge on top of line-haul rates or base rates is by its very nature a general price increase."); 2d Am. Compl. ‘|l 13. Defendants argue that since plaintiffs’ conspiracy claim is based on a component of the overall price of shipping, "[pjayrirent of a collusively-imposed fuel surcharge . . . can injure a shipper only if it caused the overall rate to be inflated above the competitive level." Class Opp. at 41. And "[g]iven that the alleged conspiracy was directed only at a portion of the total price," defendants argue that "any class niember that obtained anything of value in exchange for accepting a fuel surcharge may not have suffered impact from the alleged conspiracy." _I_d_. As defendants describe it, [i]n view of evidence that some (but not all) shippers made trade~offs for fuel surcharges, the task of determining which class members were injured (because their fuel surcharge was added to the rate with no corresponding reduction in price of other railroad concession) and which were not injured (because they were able to 102 negotiate a price reduction or other service component that the shipper valued, requires an individualized analysis of hundreds or even thousands of railroad-shipper contract negotiations ;q. at 41-42_ Defendants maintain that cases in which a conspiracy claim is based only on a component of the overall price "face a serious problem on class certification” because “[ijt is nearly impossible to deterrnine, using conimon class-wide proof, whether the alleged conspirators never reduced (or failed to raise) other elements of the price and thereby competed on an overall price basis." Class Opp. at 43 (citing Exhaust Unlirnited, Inc. v. Cintas Corp., 223 F.R.D. 506, 513 (S.D. Ill. 2004); Schoenbaum v. E.I. DuPont de Nemours & Co., Civil Action No. 05-1108, 2009 U.S. Dist. LEXIS 114080, at *35 (E.D. Mo. Dec. 8, 2009); American Seed Co. v. Monsanto Co., 238 F.R.D. 394, 401 (D. Del. 2006), gff_’d, 2008 U.S. App. I_,EXIS 6963 (3d Cir. Apr. l, 2008)). And defendants contend that this case is similar to Robinson v. Texas Auto Dealers Ass’n, 387 F.Bd 416 (5th Cir. 2004), in which the Fifth Circuit reversed certification of a class of automobile purchasers who challenged an agreement among auto dealers on how they would list an automobile tax, referred to as a Vehicle inventory Tax ("VIT"). §§ Class Opp. at 44. The Fifth Circuit in Robinson rejected the plaintiffs’ assumption that the tax was simply added to the purchase price "for every consumer in the class," concluding: Such an assumption defies the realities of the haggling that ensues in the American market when one buys a vehicle. Although some purchasers certainly negotiate a price that excludes taxes, titles, and fees, others negotiate with an eye toward the "bottom line." Bottorn-line purchasers base their negotiations on the final purchase price, including every tax, fee, and surcharge. l03 Robinson v. Texas Auto Dealers Ass’n, 387 F.3d at 423 (emphasis in original). 'l`hus, the Fifth Circuit concluded that [t]o determine whether a purchaser negotiated in a top-line or bottom-line fashion, a court would have to hear evidence regarding each purported class member and his iransacii`orr. Such an individual examination would destroy any alleged predominance present in the proposed class. The offered evidence plainly shows that the class members’ individual negotiation styles prevent the plaintiffs from arguing that all members of the class suffered an antitrust injury just by paying a Vl"i`. § at 424 (emphasis in original). Defendants contend that, if anything, this case is even less suited for class certification than Robinson because the automobile tax there never varied, whereas, here "the actual fuel surcharge assessed can and does vary from shipper to shipper - adding another variable to the negotiation over total prices." Class Opp. at 44. Defendants also assert that the evidence in the recor'd, similar to the circumstances in Robinson, shows that many of defendants’ customers negotiate toward the bottom line and frequently trade fuel surcharges for rate reductions or other benefits §_e§ Class Opp. at 45. As defendants describe it, "[t]here is overwhelming evidence that many of the sophisticated shippers constituting a substantial portion of Defendants’ customer base focus on the overall price/service package and frequently negotiate trade-offs between base rates, fuel surcharges and many other terms of service." lgl. And relying on the declarations of various railroad executives, defendants say that they have provided "nuinerous examples of major customers that negotiated items of value to them as part of their contracts that also included their agreement to pay fuel surcharges[.]" E. Thus, given the highly individualized nature of rail freight pricing, defendants l04 contend that plaintiffs cannot establish with con'imon evidence that class inernbers paid more for shipping as a result of paying the allegedly conspiratorial fuel surcharge On this point, Dr. Willig has the same view. As he explains, rail contracts are inultidiinensional, involving a wide variety of complex contractual provisions, and a shipper’s evaluation of a contract "depends on the full package of contract tenns{.]" Willig Report 11 1 16. Dr. Willig examines defendants’ transaction data and relies on defendants’ declarations to conclude that the introduction of fuel surcharges into rail contacts during the class period "often” resulted in concessions on other contract terrns. id if 122; § §. 11 123. Plaintiffs do not appear to disagree with the general proposition that evidence of discounting ~» for exarnple, reductions in a base rate - is relevant in assessing whether class certification is appropriate Dr. Rausser himself has acknowledged that if shippers received concessions in the form of base rate discounts in exchange for the application of a fuel surcharge, then the impact for those shippers "wouldn’t have been common to those" who did not receive such discounts. lst Rausser Dep. at 272; _s__@ gl_sg i_d at 270. Plaintiffs argue, however, that the depositions of defendants’ declarants, on whom defendants primarily rely for their purported evidence of discounting, have exposed that the declarations are both unreliable and inconsistent with later deposition testirnony. § Class Reply at l7. According to plaintiffs, although defendants claim that customers traded fuel surcharges for trade reductions, the depositions establish that most reductions were in fact reduced t'ncreases, and even those such situations were rare. _S__e_e _id. at 20. As for Dr. Rausser, he acknowledges that defendants’ transaction data show that a nominal amount of discounting occurred, §_e_e_ 2d Rausser Dep. at 21 l (describing "very little 105 deviations or anomalies"), but contends that there is no evidence of systematic discounting of base rates to offset increases §__e_e 2d Rausser Report at 91 ("There is no evidence of a systematic pattern of discounting base rates or providing other concessions in order to offset Fuel Surcharges[.]"); Class Reply at 14. As Dr. Rausser sees it, "there is no real-world evidence of widespread discounting of base rates, nor is there any established causal link between the isolated instances of declining base rates and the imposition of Fuel Surcharges." 2d Rausser Report at 66. The Court agrees with plaintiffs that defendants’ executives’ declarations are unpersuasive and inconsistent with their later deposition testimony. Furthennore, the Court finds by a preponderance of the evidence that any examples of discounting are, at best, anomalies that do not preclude a finding ofpredoininance. Finally, the Court concludes that the Fifth Circuit’s decision in Robinson is inapposite to this case. I. Defendants ’ declar‘az't'orts. Defendants and Dr. Willig rely heavily on the 21 declarations submitted by defendants’ executives purporting to show that many of defendants’ customers traded fuel surcharges for rate reductions Defendants point to eight such examples in their opposition papers, g Class Opp. at 45-46, and then state that they "are not trivial exceptions to a rule,” but rather "represent large revenues" and "retlect the diversity of outcomes among negotiated contracts." id_. lf defendants’ declarations provide examples of anything, it is the paucity of any evidence of discounting Relying on the declaration of George "i`. Duggan, a vice president at BNSF, defendants state 106 Cleee Opp- at 45 (citing Duggan Decl. 11 l6). But during his deposition, Mr. Duggan testified that 1 I~ilD Ex. 81, Duggan Dep. at 26-27 (elttr>heeie edded)- Thie, then, is en example of a reduced increase, not a discounting of the base rate in exchange for application of a standardized fuel surcharge. Relying on the declarations of Marc Allen and David Garin, both vice presidents at BNSP, defendants state: _In other instances, shippers agreed to pay the standard BNSF fuel surcharge in exchange for receiving other economic concessions from BNSF. Garin Decl. 11 12. Class Opp. at 45-46. Mr. Allen, however, testified that BNSF’s "standard fuel surcharge provision" was "the starting point in contract negotiations with respect to the fuel surcharge provision to be included in the contract." HD Ex. 85, Allen Dep. at 27; g i_d. at 25 ("[O]ur initial opening offer is almost always one that includes a standard fuel surcharge program.").

NS agreed." Class l Opp. at 46 (citing Listwak Decl. ‘|[ 15; Schaaf Decl. 1[ 18).

Mandates not to discount base rates. Based in large part on the deposition testimony of defendants’ own executives, the Court finds that plaintiffs have established by a preponderance of the evidence that any discounting of the base rate by defendants was rare ~»»~ which is consistent with clear mandates from defendants not to modify their standard fuel surcharge program. As an illustrative example, Donald Seale, at the time NS’ senior vice president of inarl 267 F.R.D. 583, 604 (N.D. Cal. 2010). Defendants should be "focused on disputing the use of the methodology itself, not the results of the inethodology." fn re EPDM Antitrust Litig., 256 F.R.D. at 96. In any event, the Court finds Dr. Rausser’s analysis persuasive, _se_e_ 2d Rausser Report at 57-66, and credits his determination from his review of the data that there was no evidence of systematic discounting The Court concludes that any examples of such discounting are outliers, insufficient to defeat a finding of predominance. §§ Kohen v. Pacific lnv. Mgrn.t. Co., 571 E.?)d at 677. 113 4. Starri`ng poi`iilfor' riegorz`alfor:s. Finally, the Court concludes that the Fifth Circuit’s decision in Robinson v. Texas Auto Dealers Ass’n, a case upon which defendants’ heavily rely, is inapposite to this case. The Fifth Circuit in Robinson framed the question presented as "whether the mere payment of a VIT -- unaccompanied by any other evidence - provides enough information such that a party may sustain a price~fixing suit on behalf of the entire class." Robinson v. Texas Auto Dealers Ass’n, 387 F.3d at 423. in concluding that class certification was inappropriate, the l~`iftli Circuit criticized the plaintiffs for assuming that the automobile tax at issue "represents an additional charge that artificially increases the final purchase price for every consumer in the class." Q. As the Fifth Circuit stated: Such an assumption defies the realities of haggling that ensues in the American market when one buys a vehicle. Although some purchasers certainly negotiate a price that excludes taxes, titles, and fees, others negotiate with an eye to the "bottoin line." Bottoin-liiie purchasers base their negotiations on the final purchase price, including every tax, fee, and surcharge, E. (internal footnote omitted) (emphasis in original). Thus, in order to determine whether a customer is a bottoin~lirie or top-line negotiator, the Fifth Circuit concluded that "a court would have to hear evidence regarding each purported class member aria' fits transaction," and that was fatal to a finding of predominance. i_d. at 424 (emphasis in original). Here, however, plaintiffs have presented persuasive documentary and expert opinion evidence that is common to the class that shows that the standard fuel surcharges were intended to raise overall prices as a percentage multiplier of the base rate. Because each defendant’s standardized fuel surcharge program was applied as a percentage inultipiier of a sliippei"s base rate, application of that surcharge without discounting directly had the effect of ll4 "increas[ing] all rates by a set percentage[.]” Rail Fuel Surcliarges, 2007 WL 201205, at *4. And the standardized fuel surcharges applied during the class period were uniforni, were not subject to negotiation, and were not discounted except in the case of anoinalies. Finally even w1ien, in the rare case, base rates were discounted, railroad executives admitted that the standard fuel surcharge program "even if not accepted . . . was an effort to at least influence the discussion on . . . fuel surcharge." HD Ex. 88, Gehl Dep. at 55. In other words, the allegedly conspiratorial fuel surcharges were the starting point for negotiations ~»~ a situation coinmonly observed in price fixing conspiracies where classes have been certified _S_e_:_eh, _e_”.g;, In re Universal Serv. Fund Tel. Billing Pi'actices Litig., 219 F.R.D. 661, 675 (D. Kan. 2004) (describing class actions where "‘the negotiated transaction prices would have been lower if the stating point for negotiations had been list prices set in a competitive niarket"’) (quoting ln re Industrial Diamonds Antitrust Litig., 167 F.R.D. 374, 383 (S.D.N.Y. 1996)). This case therefore is nothing like Robinson. Compare Robinson v. Texas Auto Dealers Ass’n, 387 F.3d at 423 (deciding "whether the mere payment of a Vl'l` 4 unaccompanied by any other evidence -»~- provides enough information such that a party may sustain a price-fixing suit on behalf of the entire class") (emphasis added). Instead, this case falls within the line of cases holding that class-wide injury~in-fact can be proven at trial by showing that the allegedly conspiratorial fuel surcharges were the starting point "‘froin which negotiations for discounts began."’ l_n re Universal Serv. Fund Tel. Billing Practices Litig., 219 F.R.D. at 675 (quoting In re Industrial Diainonds Antitrust Litig., 167 F.R.D. at 383); _s_e_e In re Ready-Mixed Concrete Antitrust Litig., 261 F.R.D. at 171~72. The theory behind this line of cases -~ which applies with equal force here m 115 "is . . . that the negotiated transaction prices would have been lower if the starting point for negotiations had been list prices set in a competitive market Hence, if a plaintiff proves the alleged conspiracy resulted in artificially inflated list prices, a jury could reasonably conclude that each purchaser who negotiated an individual price suffered some injury." In re Universal Serv. Fund Tel. Billing Practices Litig., 219 F.R.D. at 675 (quoting in re industrial Diarnonds Antitrust Litig., 167 F.R.D. at 383). In sum, individualized negotiations and discounts are not an automatic bar to class action treatment §§ In re EPDM Antitrust Litig., 256 F.R.D. at 89; in re Urethane Antitrust Litig., 251 F.R.D. 629, 637-38 (D. Kan. 2008); ln re industrial Diamonds Antitrust Litig., 167 F.R.D. at 383. Under this line of cases, then, the question is whether common proof can be used to show that the alleged conspiracy on fuel surcharges, at the very least, affected the starting point for negotiations. _S__e_e_ In re EPDM Antitrust Litig., 256 F.R.D. at 88-89; ln re Urethane Antitrust Litig., 251 F.R.D. at 637-38. The answer is yes. Not only have defendants’ own executives admitted that negotiations started with the standard fuel surcharge program, s_eg HD Ex. 88, Gehl Dep. at 55; HD Ex. 85, Allen Dep. at 24~27; HD Ex. 83, Lawson Dep. at 38-41; HD Ex. 77, Listwak Dep. at 23, l29; HD Ex. 89, Pagan Dep. at 55-56; HD Ex. 66, Young Dep. at 71»75, but plaintiffs have shown m in reliance on defendants’ own documents and economic analysis of defendants’ transaction data m that defendants’ standardized fuel surcharge programs overwhelmingly were applied without discounting the base rate. §_e__q supra at 106-13. iii. Expert opinions on injury-iii-fact Plaintiffs do not rely only on the extensive documentary evidence in the record to show that injury-in-fact is capable of proof at trial with evidence conimon to the class. Plaintiffs 116 also submit that they anticipate presenting at trial the testimony of Dr. Rausser, who, as they describe, confirms with economic principles common to the class and a regression analysis that injury-in-fact is capable of common proof. §<_:_§ Class Mem. at 71-75; s_e_e gi_l§r_) Class Mot., Ex. B, Trial Plan at 8-9. In his report, Dr. Rausser first discusses the rail freight industry and concludes that five structural factors strongly suggest that a conspiracy to impose supra-competitive fuel surcharges on shippers would have succeeded in subjecting the class to a common injury-in-fact. § lst Rausser Report at 10-52; 2d Rausser Report at 80-81. Then, Dr. Rausser performs economic regression analyses on defendants’ transaction data that he says reveal that class members suffered a common injury-in-fact from the alleged conspiracy. § lst Rausser Report at 80-101, 120; 2d Rausser Report at 9l-92. Dr. Rausser has developed two economic regression modeis: a "conimon factor model and a damage inodel." Oct. 6 Tr. at 137. According to plaintiffs and Dr. Rausser, "[t]hese models together show that there are identifiable common factors that explain pricing in the rail freight industry; and . . . that the conspiracy caused significant overcharges across the class." l,d.; §§ 2d Rausser Report at 91-92. Thus, plaintiffs say that Dr. Rausser has established that economic analyses relying on evidence common to the class _ defendants’ transaction data and economic principles common to the class - "can be used to show that Defendants’ conspiracy led to artificially high prices during the Class Period for Class inembers." lst Rausser Report at 80-81.3' 2' As discussed below, §§ infra at 138-39, Dr. Rausser also concludes that a common damage methodology works in this case. 117 Dr. Willig disagrees with some of Dr. Rausser’s views about the rail freight inarket. _S`Q§ Willig Report at 64-l0(). More importantly, Dr. Willig finds flaws in Dr. Rausser’s regression analyses, § i_d. at 107-59, and concludes that individualized inquiry is required to determine whether a particular shipper was injured-in-fact as a result of the alleged conspiracy _S§e_ 'l] 285. As the Third Circuit instructed in In re llydrogen Peroxide Antitrust Litig., the Court has weighed the expert reports of Dr. Rausser and Dr. Willig as a part of the rigorous analysis Rule 23 deinands. §p_e re Hydrogen Peroxide Antitrust l.itig., 552 F.3d at 323-24. The Court finds persuasive Dr. Rausser’s analysis, which supports plaintiffs’ argument that injury-in-fact is capable of proof at trial through evidence common to the class. The Court finds that Dr. Rausser’s theory is "plausible," Behrend v. Comcast Corp., 655 F.3d at 204 n.l3; § Hydrogen Peroxide Antitrust Litig., 552 F.3d at 325, and "susceptible to proof at trial through available evidence common to the class." ln re Hydrogen Peroxide Antitrust l,itig., 552 F.3d at 325. Dr. Rausser persuasively has established "the key logical steps behind [his] theory,” In re New Motor Vehicles Canadian Exp.

'I`ogether, they provide rail services throughout the continental United 118 States "to nearly every industrial, wholesale, retail, and resource-based sector of the economy." _I_c_i_. ln short, Dr. Rausser concludes that defendants have "an enormous market share in the rail freight market," and that this "structure . . . created an environment conducive to collusiori[.]" lc_l. at 20. The product at issue is freight service. _S__e_e_ 1stRausser Report at 16. As Dr. Rausser describes it, freight services are "homogenous and interchangeable across Defendants." E. at 27. He further explains: The service that the Class l railroads offer shippers is interchangeable and therefore, when shippers make a choice between railroads, they do so based on price. The service that is offered to the market is simply the movement of goods between origin and destination. Shippers can even use their own cars and often do. Any differences that may exist between shippers concerning reliability and speed are very likely to be eliminated over time as railroads compete with each other and invest to eliminate any service deficiencies they may have. lc_l. ln view of this characterization of the product, Dr. Rausser concludes that "[b}ecause customers choose between railroads based on price, there are strong incentives for railroads to restrict the resulting price competition by collusion." lc_l. Having examined the geographic market and the product at issue, Dr. Rausser contends that the rail freight industry has five characteristics that make it conducive to price fixing: (l) the industry is heavily concentrated; (2) there are significant barriers to entry; (3) rail freight services are interchangeable across defendants, and shippers choose their railroad based on price; (4) the demand for rail freight services generally is inelastic; and (5) pricing is transparent. _S__e_§ 2d Rausser Report at 79. And according to Dr. Rausser, these five characteristics strongly suggest that "had a conspiracy occurred it would have succeeded in 119 subjecting the Class to a conin'ion" injury-in-fact. 2d Rausser Report at 80. Dr. Rausser concludes: Ciiaractei'i'stic 1 -~ as the industry is concentrated in the hands of the Defendants, the alleged cartel would have been able to sustain high prices across the Class and non-Defendant railroads would have lacked the capacity to lure Class members away with lower prices; Characleri`slic 2 - the Defendaiits’ high prices would not have been undercut by the creation of new railroads (a'e novo entry), or the expansion of existing railroads; Chai‘actei‘istic 3 -e because Class members considered the railroads’ services as interchangeable and chose their railroad based on price, they would have been harmed by the restriction of that choice and the routinely imposed higher prices; Characteristic 4 _ although some shippers may have been able to find viable transport alternatives to rail (all price-fixing cartels lose some custorners), the vast majority would have been unable to do so and, thus, Defendants could profitably elevate their prices in a coordinated manner without risk of losing substantial business; Characlerisli'c 5 - costs of implementing and maintaining the conspiracy would have been extremely low due to thoroughly standardized service descriptions, established mechanisms for communicating and tracking prices, and ease of using generally available indexes to increase prices. 2d Rausser Report at 80-81 (footnotes omitted).” 22 Defendants contend that one part of "Characteristic 5" references objectionable interline-related cornniunications. §§ Defs. lnterline Objections, Ex. C, at 80-81. Specitically, defendants say that Dr. Rausser improperly has relied on interline-related communications when he states that costs of implementing and maintaining the conspiracy would have been extremely low due to "establislied niechaiiisnisfoi' coinniiuiicaiing and tracking prices[.]" E. (emphasis added). 'l`he Court has not relied on this part of Characteristic 5 in reaching in decision on plaintiffs’ motion for class certification 120 Not surprisingly, Dr. Willig disagrees with Dr. Rausser: he contends that the industry characteristics discussed by Dr. Rausser "do not suggest, and provide no valid basis for conciuding, that the alleged conspiracy would have had a systematic effect on rail rates paid by inembers of the purported class." Willig Report1[43. As Dr. Willig sees it, the economics of the rail industry imply that there can no common evidence of class~wide injury-in-fact. Willig Report at 64. Dr. Willig’s disagreement with Dr. Rausser appears to focus on two questions about the structure of the rail freight industry: whether freight prices are truly interchangeable; and whether pricing is transparent. As for the first issue, Dr. Willig contends that rail contracts involve a wide variety of complex contractual agreements and are inultidimensional in nature. Willig Report 11 115. Dr. Willig concludes: Testimony from defendants’ marketing personnel as well as defendants’ transaction data demonstrate that FSCS cannot be viewed in insolation from the other dimensions of agreements between railroads and shippers. Rather, only an individualized inquiry can determine whether shippers benefitted froin modification of other parts of the agreement as part of their agreement to pay an FSC. The existence and magnitude of such modifications cannot be measured on a class-wide basis since they depend upon the terms of both rate and non-rate provisions of the agreements Willig Report 11 115. According to defendants, they "do not provide a product, much less a fungible coinmodity"; rather, they "provide the inajority of their services pursuant to contracts that reflect the diversity of rail customers and are highly differentiated, varying by customer, lane, equipment, product being sliipped, and numerous other factors." Class Opp. at 58; se_e wang Report 11 116. 121 Regardiiig the second issue, Dr. Willig contends that Dr. Rausser’s claim that pricing is transparent is incorrect Willig Report ‘il 43. According to Dr. Willig, "rates typically paid by members of the proposed class are confidential and are not transparent to other menibers of the alleged conspiracy." I_c_l_. This industry characteristic, Dr. Willig says, "creates practical incentives for members of the alleged cartel to ‘cheat’ or ‘deviate’ by offering concessions to shippers on base rates, fuel escalation provisions, or other elements of rail contracts." @. The Court finds persuasive Dr. Rausser’s characterization of the rail freight industry. There is no question that the rail freight industry is concentrated in the hands of the four defendants - they possess 90 percent market share based on track miles and control 94 percent of the market based on freight revenue w and Dr. Willig does not claim otherwise. Nor does Dr. Willig dispute Dr. Rausser’s contention that there are signiiicant barriers to entry. As for the nature of the product, the Court disagrees with defendants that "there are a lot of individualized factors that drive shippers to choose between different rail freight service providers." Oct. 6 Tr. at 32. Dr. Rausser persuasively has explained that customers routinely switch between railroads for shipments along the same routes, "confirining that they see the railroads’ services as interchangeable." lst Rausser Report at 2'7; §§ E. at 27-29. The Court also credits Dr. Rausser’s conclusion that demand for freight services generally is inelastic. § lst Rausser Report at 29-36. As he explains, "an analysis of the industry demonstrates that Defendants’ businesses are concentrated in commodities and distances over which rail is the most cost efficient transport option and therefore the demand that they faced was in general ineiastic." l_gl". at 31-32. 122 Finally, regarding the issue of transparency, Dr. Rausser acknowledges, as he inust, the existence of private contracts, but explains that rail freight pricing nevertheless is established, well defined, and easily understood _S_e_e lst Rausser Report at 37.23 As Dr. Rausser States: "[F]reight railroad companies use common types of price aitthorily documents, which provide a detailed account of all the base freight charges, surcharges, accessorial, and fuel surcharges associated with a specified rail inovernent." i_d_. at 37 (einphasis in original). Although rail freight is, of course, a service, rather than a good, "that service is well defined and highly standardized using coniinodity classifications for the material shipped, tonnage as a measure of quantity, and miles representing the distance traveled." 2d Rausser Report at 29. Thus, "[i]ntelligence on price quotes for this service can be exchanged and both parties in the exchange know exactly what they are talking about," which "eases the costs of monitoring for a caitel." _I_gl_. Moreover, the allegedly conspiratorial inechanisin applied by defendants _ standardized fuel surcharges ~ does not require constant communications once the details of the surcharge have been agreed upon. _S__e_e_ lst Rausser Report at 50. And although Dr. Willig contends that the existence of private price quotes creates practical incentives to "cheat" or "deviate" by offering concessions, §e_e_ Willig Report ‘l§ 43, as the Court previously has found by a preponderance of the evidence, § s_up_r_g at 106, the examples of discounting are, at best, anornalies. 23 l\/loreover, as Dr. Rausser points out, the existence of private price agreements in the rail freight industry does not distinguish the industry "from many other industries, including some that have experienced price fixing despite the supposedly confidential nature of customer contracts." 2d Rausser Report at 10 & n.l6 (citing peer-reviewed study concluding that "cartels in industries with fuller reporting on prices are not statistically significantly higher than for cartels in other industries"). » 123 The Court therefore is not persuaded by Dr. Willig’s characterization of the rail freight industry, ge Willig Report‘l§1l43, 115-16, or by defendants’ attempts to discredit Dr. Rausser’s analysis. _S_g§ Defs. Hr’ g Binder, Part IlI at 45; Oct. 7 Tr. at 222-35. Rather, the Court finds that the five structural characteristics of the rail freight industry identified by Dr. Rausser, and the evidence he marshals regarding those characteristics, provide strong support for plaintiffs’ contention that injury-in-fact is capable of proof at trial with evidence common to the class. §§ In re Puerto Rican Cabotage Antitrust Litig., 269 F.R.D. at 139 (considering, among other things, highly concentrated industry, high entry barriers, static elasticity, and price competition in finding by a preponderance of the evidence that predominance requirement was satisfied); ln re EPDl\/l Antitrust Litigi., 256 F.R.D. at 92 (according to expert analysis credited by the court, certain market factors "lay the groundwork for plaintiffs’ arguinent that, if collusive behavior did occur, it would have been effective in raising prices across the class, thus demonstrating class-wide injury»in~fact"). 2. Backgrouricl on multiple regression analysis The centerpiece of Dr. Rausser’s report focuses on two economic models that examine defendants’ transaction data through multiple regression analysis. § 2d Rausser Report at 91-92; § all § at 1 l. Before addressing the specific analyses done in this case, the Court provides below some background on multiple regressions in general, as set forth in a reference guide published by the Federal Judicial Center: Multiple regression analysis is a statistical tool for understanding the relationship between or among two or more variables. Multiple regression involves a variable to be explained - called the dependent variable »-~ and additional explanatory variables that are thought to produce or be associated with changes 124 in the dependent variable. For example, a inultiple regression analysis might estimate the effect of the number of years of work on salary. Salary would be the dependent variable to be explained; years of experience would be the explanatory variable. Multiple regression analysis is sometimes well suited to the analysis of data about coinpeting theories for which there are several possible explanations for the relationships among a number of explanatory variables. Multiple regression typically uses a single dependent variable and several explanatory variables to assess the statistical data pertinent to these theories. . . . {For example, ]in an antitrust cartel damages case, the plaintiffs expert might utilize inultiple regression to evaluate the extent to which the price of a product increased during the period in which the cartel was effective, after accounting for costs and other variables unrelated to the cartel. The defendant’s expert might use multiple regression to suggest that the plaintiffs expert had omitted a number of price-determining variables More generally, inultiple regression may be useful (l) in determining whether a particular effect is present; (2) in measuring the magnitude of a particular effect; and (3) in forecasting what a particular effect would be, but for an intervening event . . . Multiple regression analysis can be a source of valuable scientific testimony in litigation. However, when inappropriately used, regression analysis can confuse important issues while having little, if any, probative value. RUBiNFELo, supra, at 305~08. "In an antitrust suit, plaintiffs will generally use multiple regression analysis to demonstrate that a ‘conspiracy’ variable has influence over the dependent variable (price) - that is, class members paid a higher price than the basic economic principles of supply and demand would otherwise dictate, thus demonstrating collusive behavior was at work." In re EPDM Antitrust Litig., 256 F.R.D. at 95; § Schumacher v. 'l`yson fresh Meats, Inc., Civil Action No. 02~1027, 2006 WL 47504, at *l n.l (D.S.D. Jan. 5, 2006) ("A inultiple regression analysis is 125 a statistical tool that atteiripts to reveal relationships between explanatory variables and a dependent variable."). A inultiple regression model must, of course, be correctly set up for the results to be valid. The expert’s choices are crucial for the success of the analysis and the ultimate fact-finder should consider the following when evaluating the efficacy of the expert’s analysis: has the expert correctly identified the dependent variable; has he or she chosen the correct explanatory variable that is relevant to the question at issue; are the additional variables chosen all correct or are some missing and/or irrelevant; is the form of the analysis correct? In re EPDM Antitrust l,itig., 256 F.R.D. at 95; g Roizii~irai.o, supra, at 310-17. Ultimately, "[e]ven the best regression equation cannot prove causation." Schuinacher v. Tyson Fresh Meats, Inc., 2006 WL 4'7504, at *'7; §§ RuaiNFnLi;>, _sgpg@, at 310. Rather, "[t]he most it can show is a con‘elation that can give rise to an inference that causation exists."

'l`hus, "one must infer that a causal relationship exists on the basis of an underlying causal theory that explains the relationship between the two variables." RUBINFELD, gi_gr_za_, at 3 l0. 3. Dr. Rausser ’s regressi`on.s' are workable and su.s'ceptlble to pi'oof`at tr‘lal llzi'ouglz cameron evi`clence. As discussed, Dr. Rausser explains that he developed two multiple regression inodels, a coinmon factor model and a damage rriodel, that together reveal that 126 injury-in-fact can be established at trial with evidence common to the class. Y, gg;, 2d Rausser Report at 91~92, 99~100; §;e_e_ _a_l_§_p_ Oct. 6 Tr. at 137. As Dr. Rausser describes it, his common factor model performs "an investigation of whether . . . common transaction characteristics predominate over individual factors in determining the variation in freight rates." 2d Rausser Report at 84. Dr. Rausser analyzed defendants’ transaction data and concluded that there are seven common factors that predominately explain rail price variations, and that these factors can be controlled for in a regression. g lst Rausser Report at 92. ln other words, according to Dr. Rausser, his common factor model explains pricing in the rail freight industry and shows, relying only on defendants’ transaction data, that rail freight pricing is "highly standardized.” E. at 84. According to Dr. Rausser, the seven factors that predominately explain rail price variations are: (l) weight of the shipment; (2) distance; (3) whether the shipment is interline; (4) the origin and destination; (5) the con'imodity being transported; (6) the rail car type; and (7) the quarter of departure. _S»_e_:t_: lst Rausser Report at 92. Dr. Rausser concludes that these seven factors are highly predictive of freight rates: he says that these factors explain "over 75% of the variation in actual per car revenues for individual shipments." 2d Rausser Report at 66-67. Because, according to Dr. Rausser, the seven common factors predominate over individual factors in determining rail freight price, the seven common factors can be used in a common analysis of iinpact. §;;_g 2d Rausser Report at 67; Y_e alj lst Rausser Report at 7 (statirig that "coininon factors can be measured using the Defendants’ transaction data and used in a common analysis to identify and quantify the harm experienced by the Class"). Dr. Rausser’s damage model builds on the common factor model to show, again relying on defendants’ transaction data, that the alleged conspiracy injured class iiienibers by 127 inflating freight prices and to quantify the amount of damages. _Sg%_ 2d Rausser Report at 91-92. Dr. Rausser says that the damage model works by taking into account the factors that influenced defendants’ prices during the class period as cornpared to "benchinark" prices during the three preceding years. lst Rausser Report at l 13. Dr. Rausser says that his regression analyses - applied now to 100 percent of defendants’ transaction data, §§ 2d Rausser Report at 12 m find "that all-in freight rates were higher during the Class Period than could be explained by economic forces other than the alleged price-fixing eonspiracy" and reveal "a structural break in the relationship between fuel prices and freight rates starting in 2003, consistent with the advent of a price~fixing conspiracy using Fuel Surcharges as its facilitating inechanism." I_d. at 82-83; §§ lst Rausser Report at 120. Dr. Rausser’s damage model calculates a class-wide overcharge of 13.4 percent. __S__e_e 2d Rausser Report at 83; lst Rausser Report at 119~20. Defendants and Dr. Willig argue that Dr. Rausser’s economic regressions suffer from fatal flaws, and that neither his common factor model nor his damage model satisfies plaintiffs’ burden of showing that injury-in-fact is capable of proof at trial with common evidence. y Class Opp. at 63. As for the common factor model, defendants contend that it has four flaws. Y i_d. at 63~65. First, defendants contend that Dr. Rausser "only studied traffic destined for three geographic areas out of the thousands served by Defendants and only for a single year -~- 2006." § at 63. The three destinations that he chose, according to defendants, are not representative samples I_d. Second`, defendants argue that although Dr. Rausser’s model shows that certain characteristics "play an important role in overall rail rates," it "says nothing about whether the conspiracy caused all class inembers to pay a fuel surcharge they otherwise would not have paid or how that fuel surcharge compared to whatever cost recovery inechanisin 128 would have been used instead." E. at 64. Third, defendants argue that Dr. Rausser’s model "purports to explain 76~89% of the variation in overall rates," but provides "no scientific basis to dismiss the ll-Z~ 2012 WL 253298, at *4 (N.l). Cal. Jan. 26, 2012) ("Defendants have not challenged the reasonableness of plaintiffs’ methodology for proving classwide impact. lnstead, their arguments concern the application of that methodology. Such analysis, liowever, goes beyond the inquiry at the class certification stage.") (citing ln re Graphics Processing Units Antitrust l_.itig., 253 F.R.D. 478, 490 (N.p. car 2003))?" 24 Both sides and their experts reference and rely on a 2009 study that was conducted by Laurits R. Christensen Associates, Inc. and commissioned by the STB to analyze competition, capacity, and service quality in the rail freight industry. _S_;;_g, _e;g;, Oct. 6 Tr. at 140-4]; Oct. 7 Tr. at 2?2-73; g;<_: generally HD Ex. 12, Li\uiurs R.

The Court concludes that they are: Dr. Rausser has established "the key logical steps behind [his] theory" that injury-in-fact is capable of proof at trial with common evidence. ln re New Motor Vehicles Canadian Exp. Antitrust Litig., 522 F.3d at 26. Relying on principles common to the class and an analysis of 100 percent of defendants’ transaction data, Dr. Rausser has presented a workable regression analysis that is susceptible to proof at trial through available evidence common to the class. § Behrend v. Comcast Corp., 655 F.3d at 198; in re l~lvdrogen Peroxide Antitrust Litig., 552 F.3d at 325. The burden for plaintiffs at the class certification stage is to show by a preponderance of the evidence "that the element of antitrust impact is capable of proof at trial through evidence that is common to the class rather than individual to its ineinbers." ln re Hydrogen Peroxide Antitrust Litig., 552 F.3d at 311-12. Plaintiffs have satisfied that burden. The Court has examined all the relevant evidence and arguments including all relevant expert opinion, _Y_e § at 315 n. l 3, and finds by a preponderance of the evidence that plaintiffs have shown that impact is capable of proof at trial through common evidence. "Christensen Report"). Plaintiffs say that the Christensen Report supports Dr. Rausser’s conclusion that there was a structural break in the relationship between fuel costs and rail freight prices that was consistent with the start of the alleged conspiracy. _Y_e Oct. 6 'l`r. at 140-41; _s_e_e_: § Christensen Report at 9-16~9-17. Defendants say, among other things, that the Christensen Report "does quite the opposite." Oct. 7 Tr. at 272. Defendants do not dispute, however, that the Christensen Report relies on evidence common to the class and itself constitutes such coinmon evidence. 'i`hus, if anything, the Christensen Report supports plaintiffs view that injury-in-fact is caj)able of coinmon proof at trial. The question of which party’s characterization of that report is correct is a rnatter to be resolved by the finder of fact at trial. 136 3. Damages The third element that plaintiffs will have to prove at trial is "ineasurable datnages." In re Hvdrogen Peroxide Antitrust Litig., 552 F.3d at 311; l\/leijer, Inc. v. Warner Chilcott Holdings Co. lll, 246 F.R.D. at 307. The element of damages is distinct from impact: impact asks "\»vhetlzer the plaintiffs were harmed," whereas damages "quantify by how rrzuch." ln re EMDM Antitrust Litig., 256 F.R.D. at 88 (emphasis in original). "The inquiry for a district court at the ciass certification stage is whether the plaintiffs have demonstrated by a preponderance of the evidence that they will be able to measure damages on a class~wide basis using common proof." Behrend v. Comcast Co;p., 655 F.3d at 204. "Some variation of damages among class inembers does not defeat class certification." Behrend v.

Moreover, as the Seventh Circuit recently stated: "It is well established that the presence of individualized questions regarding damages does not prevent certification under Rule 23(b)(3)."

City Optical Inc., 39 F.3d 765, 771 (?th Cir. ]994) (recogriiziiig that "[t]here have been inany antitrust class actions in which the relief sought was damages, and the fact that the damages would generally be different for each rnember of the class was not deemed an insurperable obstacle"); § also Kottaras v. Whole Foods Mkt., Inc., 2012 WL 259862, at *?. To be sure, however, "[c]oinplex and individualized questions of damages . . . weigh against finding predominance." Behrend v. Comcast Corp., 655 F.?>d at 204. Plaintiffs rely on Dr. Rausser to show that analysis common to the class can be used to calculate and apportion class-wide damages among ciass members. § Class Mem. at 75. As plaintiffs describe it, Dr. Rausser has observed that “it is entirely feasible to perform the estimation of the percentage overcharge across the entire class for each regression specification described in his report, yielding a caicuiation of overcharge for the entire class." E. According to Dr. Rausser, his analysis reveals that "a professionally accepted regression based methodology using the Defendants’ transaction data . . . does in fact work" in assessing class-wide damages lst Rausser Report at 1 13. As Dr. Rausser expiains, he "developed such a regression niodel" - that is, his damage modei -- "to test whether the prices during the Class Period are significantly different than prices generated from an appropriate ‘bencliinark’ period, after adjusting for differences in all relevant economic forces." lc_l. Dr. Rausser has calculated class-wide damages using his damage inodel einployiiig the conspiracy and pre-conspiracy transaction data: The percentage overcharge due to the alleged conspiracy can be calculated using the regression model to coinpare freight rates in the Class Period to those in the pre-Class Period, while using the 138 Defendants’ transaction data and publicly available data to account for the other predominating common economic forces that determine prices. The transaction data can be used to account for the effect of shipment specific cliaracteristics, such as weight, distance, route, car type, coinmodity type, and so on. . . . The regression model can be used to "back out" the effect of these factors to isolate the effect of the alleged conspiracy on freight rates. lst Rausser Report at ll4. He further adds that "to calculate each individual custorner’s damages[,] the relationship between price drivers and freight rates calculated by the model mn on the full range of data can be used to estimate the but-for price for each customer transaction." I_d. at 122. 'I`hus, the "difference between this but-for price and the actual price paid is the overcharge to that customer for that transaction." at 122-23. Defendants argue that "the complications of the individualized proof of damages here preclude class certification." Class Opp. at 72. As defendants describe it, in most price ` fixing cases, plaintiffs will propose to calculate a standard overcharge percentage, which then is applied to all class member purchases. §§ _i_d. at 73. In that situation, defendants contend that an assessment of damages is not particularly compiicated: °‘the only individualized task is to tally up a class member’s purchases, which are then multiplied by the common overcharge percentage." Id. Here, however, defendants argue that determining individualized damages requires evidence of, among other things: (l) the [individual] class inember’s actual fuel surcharge payments, (2) the but-for fuel cost recovery that would have applied to that class inember in light of its specific competitive situation, including both the timing of when that fuel surcharge would have been added and its terms, and (3) other adjustments to the base rate or non-rate elements of the contract that were made as part of the negotiations to add the fuel surcharge, 139 Class Opp. at 73. According to defendants, "[t]liese are all individualized determinations," and Dr. Rausser’s damage model "does not account for any of these elements and therefore cannot be used to estimate an individual class inember’s damages." ld. 'I`hus, defendants contend that class certification niust be denied. §§ _ig_ at 73-74 (citing Piggly Wiggly Cfarksville, lnc. v. interstate Brands Corp., 2l5 F.R.D. 523, 530-31 (E.D. Tex. 2003)); _s__e_§a_lg)_ Willig Report at 137-5 l.. The Court disagrees with defendants and finds that plaintiffs have satisfied their burden of showing by a preponderance of the evidence that "they will be able to measure damages on a class-wide basis using common proof." Behrend v. Comcast Corp., 655 F.3d at 204. Dr. Rausser has developed a workable regression model that uses defendants’ transaction data to calculate damages to the class and to each class member. in his original repoit, Dr. Rausser applied his regression methodology on a dataset that included about 25 percent of each defendants’ total unregulated freight traffic over the period 2000 to 2008. _$__e_e_ Class Reply at 37. As Dr. Rausser explains in his reply report, he now has run his regression model on the complete set of defendants’ transaction data. §_§_;Q 2d Rausser Report at 96; § rul Class Reply at 3'7. And, according to Dr. Rausser, "[t]he results on 100% of the relevant transactions confirm that a structural break in the relationship between fuel prices and freight rates occurred in 2003, and that this break increased freight rates above what they would have been absent the conspiracy. The estimated class-wide overcharge is 13.4%." 2d Rausser Report at 83. Furthermore, as Dr. Rausser explains, his damage model "does not assume that all shippers paid the same overcharge." 2d Rausser Report at 92. Rather, he explains that his damage model "can be used to calculate individual damages[.]" Q. 140 The Court rejects defendants’ argument that Dr. Rausser’s damage model cannot be applied on a class-wide basis to calculate damages because such damages vary on particular shipments. § Class Opp. at 65; Willig Report 11 2'73. Even if that were true, it would not preclude a finding of predo1ninance. _S_§g Messner v. Northshore Univ. HealthSystem, 699 F.3d at 815; §§ supra at 137-38. And in any event, the Court agrees with Dr. Rausser that the reported variation among shipments is to be expected and does not prevent a common damage methodology from applying in this case. g 2d Rausser Report at 98 n.225. The Court also rejects defendants’ argument that Dr. Rausser’s damage model "yields nonsensical results." Class Opp. at 66. As defendants describe it: "Dr. Rausser says injury to class members results from the payment of fuel surcharges, but the damages he calculates, which are expressed as percentage reductions in all-in-rates, vastly exceed the fuel surcharges actually assessed." I_d.; _s_eg Willig Report 1§1] 258-60. The Court agrees with plaintiffs that this criticism is misplaced. As Dr. Rausser persuasively explains: My damage methodology pertains to all-in rates, rather than merely the increase in Fuel Surcharge percentages, and estimates how much those all-in rates increased as a result of Defendants’ conspiratorial conduct. As documented throughout the discovery record, the Fuel Surcharge is the facilitating mechanism used by Defendants to increase these all-in rates. The computed all-in overcharge which l have arrived at using 100% of the transaction data is 13.4%, a figure well below the average percentage Fuel Surcharge imposed during the Class Period. 2d Rausser Report at 96 (emphasis in original). To the extent that there are instances where calculated overcharges do exceed the fuel surcharges assessed, the Court credits Dr. Rausser’s explanation that this reflects various factors, including, for example, instances of "double-dipping" - that is, when fuel surcharges were applied on top of base rates that 141 themselves already have built-in fuel cost recovery mechanisms -- and instances of rebasing. §§ at 96. As the Third Circuit recently stated: "At the class certification stage we do not require that Plaintiffs tie each theory of antitrust impact to an exact calculation of damages, but instead [require] that they assure us that if they can prove impact, the resulting damages are capable of measurement and will not require labyrinthine individual calcu1ations." Behrend v. Comcast Corp., 655 F.3d at 206. The Court is persuaded that Dr. Rausser’s damage model satisfies this burden, and the Court finds by a preponderance of the evidence that plaintiffs "will be able to measure damages on a class-wide basis using common proof." id at 204. B. Superiority 'The second requirement of Rule 23(b)(3) is superiority: a court must find "that a class action is superior to other available methods for fairly and efficiently adjudicating the controversy." FED. R. Civ. P. 23(b)(3); §§_e Meiier, lnc. v. Warner Chilcott Holdings Co. lll, 246 F.R.D. at 3 13. This requirement "ensures that resolution by class action will ‘achieve economies of time, effort, and expense, and promote . . . uniformity of decision as to persons siinilarly situated, without sacrificing procedural fairness or bringing about other undesirable consequences." l\/leijer, Inc. v. Warner Chilcott l~loldings Co. III, 246 F.R.D, at 313 (quoting Arnchein Prods Inc. v. Windsor, 521 U.S. at 615) (alteration in original). "When common questions are found to predominate, then courts also generally have ruled that the second prerequisite of Rule 23(b)(3) »-»- that the class suit be superior to any other available means of settling the controversy - is satisfied in the context of an antitrust 142 action." in re Readv-Mixed Concrete Antitrust Litig., 261 F.R.D. at 173 (quotations oinitted). 1n contrast, when individual issues predominate, a class action will be deemed inferior. _$_e_§ McCarthy v. Kleindienst, 741 F.2d at 14l 5; §_e_e also Williains v. Glicl 1997 WL 33772612, at *ll (D.D.C. Feb. l4, 1997) ("The greater the number of individual issues, the less likely superiority can be established."). Defendants contest the superiority requirement on the same grounds as they contest predorninance: they say that a class action is inferior because individual issues predominate regarding injury and damages. g Class Opp. at 74-75. But as the Court has concluded, individual issues do not predominate, and so the Court finds that plaintiffs have satisfied the superiority requirement. This case involves approximately 30,000 shippers, and plaintiffs have shown by a preponderance of the evidence that the elements of plaintiffs’ Sherman Act claim are capable of proof at trial through evidence that is common to the class. Given the size, complexity, and expense of this case, the Court finds that class action treatment is superior to any other available methods for fairly and efficiently adjudicating plaintiffs’ claim. § FED. R. CIV. P. 23(b)(3). The Court has considered plaintiffs’ proposed trial plan, § Class Mot., Ex. B, Trial Plan at l-l0, as well as any possible difficulties in a trial on plaintiffs’ Sherman Act claim. Y Class Opp. at 77-78. The Court concludes that the resolution of this case by class action will "‘achieve economies of time, effort, and expense, and promote . . . uniformity of decision as to persons siinilarly situated, without sacrificing faimess or bringing about other undesirable consequences." Meiier, lnc. v. Warner Chilcott Holdings Co. 111, 246 F.R.D. at 313 (quoting Amchem Prods lnc. v. Windsor, 521 U.S. at 615). 143 Vl. CONCLUSION F or the foregoing reasons, the Court finds by a preponderance of the evidence (l) that plaintiffs have established each fact necessary to meet the requirements of Rule 23 of the Federal Rules of Civil Procedure; and (2) that plaintiffs have established that the elements of their Sherman Act claim are capable of proof at trial through evidence that is common to the class rather than individual to its members. Therefore, the Court will grant the motion of the direct purchaser plaintiffs’ for class certification [Dkt. No. 337]; will certify this case as a class action under Rule 23(b)(3) for purposes of litigation and trial; will define the class as proposed by the direct purchaser plaintiffs’ in their motion for class certification; will certify for class treatment the direct purchaser plaintiffs’ claim for price fixing in violation of Section 1 of the Sherman Act, 15 U.S.C. § l; will designate the eight named plaintiffs as the class representatives; and will appoint Quinn Emanuel Urquhart & Sullivan, LLP and Hausfled LLP as co-lead class counsel for the class. The Court will not rule at this time on the motion of the defendants to exclude interline-related communications from consideration for class certification or for any other purpose {Dkt. No. 4l7]. This Opinion temporarily has been issued under seal in its entirety in view of the possibility that the Court has referenced "Conlidential" or "Highly Conlidential - Attorneys’ Eyes Only" material, as described in the Protective Order issued in this case. §_5;§ Protective Order ‘|ljl 1.3, l.4, Jan. 29, 2009 (Facciola, l\/lag. .l.)
