    OPINION
    PER CURIAM                                              DECIDED: December 15, 2014
    This discretionary appeal concerns whether the class action proceedings in this
    case improperly subjected Appellants to a “trial by formula.” The trial court certified the
    class, a jury rendered a divided verdict, and the Superior Court affirmed in part and
    reversed in part. We now affirm.
    Appellees brought various class action claims against their former employers,
    Wal-Mart Stores, Inc., and Sam’s Club (hereinafter “Wal-Mart”), based on policies and
    conduct pertaining to rest breaks and meal breaks. Appellees asserted that Wal-Mart
    had promised them paid rest and meal breaks, but then had forced them, in whole or in
    part, to miss breaks or work through breaks, and also to work “off-the-clock,” i.e., to
    work without pay, after a scheduled shift had concluded.1 The trial court certified a
    class consisting of “all current and former hourly employees of Wal-Mart in the
    Commonwealth of Pennsylvania from March 19, 1998 to the present December 27,
    2005.” See Order, 12/27/05, at 1. The class ultimately consisted of 187,979 members.
    The jury trial of this class action alleging systemic wage and hour violations
    spanned six weeks, resulting in a voluminous record. Appellees called eighteen fact
    witnesses and three expert witnesses during their case-in-chief.             The parties’
    examinations of Appellees’ expert witnesses took six full days of trial (September 11,
    12, 13, 19, 20, and 21). Additionally, lengthy arguments were conducted during trial but
    outside the hearing of the jury on Wal-Mart’s motions to strike portions of the testimony
    of Appellees’ experts. Ultimately, the jury rendered a verdict in favor of Wal-Mart on all
    1
    Appellees alleged claims against Wal-Mart for breach of contract, unjust enrichment,
    and violations of the Pennsylvania Wage Payment and Collection Law (“WPCL”) and
    Pennsylvania Minimum Wage Act (“PMWA”).
    [J-43A&B-2013] - 2
    claims relating to meal breaks but in favor of Appellees on all claims relating to rest
    breaks and off-the-clock work. The amount of the judgment ultimately entered on the
    verdict was $187,648,589.2 Wal-Mart appealed the judgment, and the Superior Court
    affirmed in part and reversed in part in a published unanimous per curiam opinion,
    which corrected a patent mathematical error committed by the trial court,3 reversed the
    award of attorneys’ fees, and remanded to the trial court to recalculate the lodestar it
    had employed to determine the amount of attorneys’ fees. Braun v. Wal-Mart Stores,
    Inc., 
    24 A.3d 875
     (Pa. Super. 2011).       This Court granted Wal-Mart’s request for
    discretionary review, limited to the following issue framed by Wal-Mart:
    Whether, in a purported class action tried to verdict, it
    violates Pennsylvania law (including the Pennsylvania Rules
    of Civil Procedure) to subject Wal-Mart to a “Trial by
    Formula” that relieves Plaintiffs of their burden to produce
    class-wide “common” evidence on key elements of their
    claims.

    47 A.3d 1174

    This amount breaks down as follows:
    WPCL verdict:                               $ 49,568,541
    Common Law verdict:                         $ 29,178,873
    Statutory Interest:                         $ 10,163,863
    WPCL liquidated damages:                    $ 62,253,000
    WPCL attorney fees:                         $ 33,813,986
    WPCL expenses:                              $ 2,670,325
    Additional attorney fees in the amount of $11,880,589 and expenses of $938,222 were
    ordered to be paid from the fund arising from the common law verdict.
    3
    The Superior Court’s correction of the error reduced the WPCL verdict amount from
    $49,568,541 to $49,289,541.
    [J-43A&B-2013] - 3
    The issue accepted for review requires this Court to address: (1) whether Wal-
    Mart was subjected to a “trial by formula”; and (2) whether Appellees were thereby
    improperly relieved of their burden to produce class-wide common evidence on key
    elements of their claims. Notwithstanding Wal-Mart’s inclusion of the phrase “purported
    class action” in the issue presented for review, the propriety of the certification of the
    class in the first instance is not before the Court in this appeal. Notably, however, much
    of Wal-Mart’s challenge to the method of trial is premised upon its contention that the
    class never should have been certified because Appellees did not present sufficient,
    class-wide “common” evidence of contract formation, breach, or unjust enrichment.
    Moreover, Wal-Mart asserts that the trial court’s class certification, the jury verdict, and
    the Superior Court affirmance all improperly relied upon “sham statistics and baseless
    extrapolations of [Appellees’] expert witnesses, Drs. Baggett and Shapiro[,]” regarding
    “Wal-Mart’s time clock and cash register records.” Appellants’ Brief at 27, 30. In short,
    Wal-Mart asserts that Appellees’ statistical and extrapolation evidence was flawed in
    that it failed to show “that class members, on a class-wide basis, missed breaks, took
    shortened breaks or worked off-the-clock.” Id. at 18-19.
    More specifically, Wal-Mart claims that the time clock and cash register records
    did not show that employees had been forced to miss breaks or work off-the-clock, and
    that Appellees’ expert analysis reaching the opposite conclusion was based on faulty
    assumptions that failed to account for the actual practices of Wal-Mart and its
    employees. Specifically, Wal-Mart claims that the analysis regarding rest breaks failed
    to account for “voluntary” missed breaks, and that the analysis regarding off-the-clock
    work failed to account for the alleged fact that it was not uncommon for cashiers to log
    into and operate cash registers under another employee’s name.             Thus, Wal-Mart
    asserts that the class was overbroad, that appellees had not shown proper proof of Wal-
    [J-43A&B-2013] - 4
    Mart’s liability as to each “purported” class member, and that Wal-Mart had been
    subject to a “trial by formula” that denied Wal-Mart its right to due process in violation of
    Pennsylvania law.4 Appellants’ Brief at 18-19. Specifically, Wal-Mart claims it was
    denied the right to defend inherently individual issues of liability. Id. at 22-24.
    The Superior Court’s slip opinion in this case is 211 pages long, and thoroughly
    details the evidence presented at trial. We set forth here only those facts necessary for
    resolution of the single issue raised on appeal, in which Wal-Mart challenges the
    method by which the trial was conducted.
    Wal-Mart employees (characterized as “associates” in Wal-Mart’s employee
    handbooks and other written policies) are required to “punch” time clocks.            During
    orientation for new employees, employee handbooks are distributed that, among other
    things, inform employees that they are entitled to paid rest breaks and that they will be
    paid for all hours worked. Additionally, all employees are informed, through a variety of
    means, about Wal-Mart’s rest break policy, known as PD - 07, and its off-the-clock work
    policy, known as PD - 43. The rest break policy states that a paid, 15-minute break will
    be given to an employee who works between three and six hours, and that an additional
    paid, 15-minute break will be given to an employee who works more than six hours.
    The rest break policy requires that employees take full, uninterrupted breaks, and warns
    that disciplinary action may result if an employee misses breaks or takes breaks that are
    either too long or too short. Wal-Mart’s off-the-clock work policy provides that it is
    against company policy for any employee to perform work without being paid, and that
    employees will be compensated for all work performed.
    Prior to February 10, 2001, Wal-Mart employees were required to clock out and
    clock back in for each rest break, i.e., employees were required to “punch” or “swipe” a
    4
    There are no federal due process claims asserted.
    [J-43A&B-2013] - 5
    time clock at the beginning and end of every rest break. Beginning in 1999, Wal-Mart
    conducted approximately ten regional internal audits that indicated widespread rest
    break violations, such as missed breaks, breaks that were too long, or breaks that were
    too short. In 2000, Wal-Mart conducted the “Shipley Audit,” which was national in scope
    and included an examination of time clock and cashier log-in records. The Shipley
    Audit revealed that in one week, across 127 Wal-Mart stores, including five in
    Pennsylvania, more than 60,000 rest break violations had occurred. The Shipley Audit
    showed that an average of two rest breaks per week per employee were either missed
    or shortened at every store. The results were reported to top-level Wal-Mart executives,
    and on February 10, 2001, Wal-Mart eliminated its policy requiring employees to clock
    out and clock back in for each rest break.5 Additionally, there was evidence that, prior
    to 2003, it was possible for Wal-Mart cashiers to log in to and operate cash registers
    even if they were “off-the-clock.”    In 2003, Wal-Mart instituted a “lock-out” system
    whereby no employee who was off-the-clock could log in to a cash register. However,
    the system permitted managers to override lock-outs, i.e., to enable an off-the-clock
    employee to log in to and operate a cash register.
    In both seeking certification of the class and litigating their case at trial, Appellees
    presented the expert opinions of statisticians L. Scott Baggett, Ph.D., and Martin M.
    Shapiro, Ph.D., who had analyzed Wal-Mart’s own business records regarding hours
    worked, breaks taken, and wages paid to each employee, as well as the results of the
    Shipley Audit.6   At trial, Dr. Baggett testified that he had been provided the hourly
    5
    Wal-Mart stipulated at trial that as of one month prior to the change in policy, lawsuits
    alleging violations of Wal-Mart’s rest break policy had been filed in seven states:
    Colorado, Indiana, Louisiana, New Mexico, North Carolina, Ohio, and Texas.
    6
    Wal-Mart maintained “Time Clock Archive Reports” that showed total hours worked
    and total breaks taken by every employee for every shift worked. Wal-Mart’s “Time
    (Kcontinued)
    [J-43A&B-2013] - 6
    employee time clock, rest break, and payroll records for all 139 Wal-Mart stores in
    Pennsylvania for the period from 1998 through early 2006, which amounted to 46 million
    individual shifts.   Dr. Baggett further testified that the data provided had been
    incomplete, and that statistical extrapolation from the data revealed that, in fact, 52
    million individual shifts had occurred during that time period; he testified that his
    computation of that total had been formulated within a reasonable degree of statistical
    certainty. Dr. Baggett also explained his methodology for determining how many rest
    breaks should have been earned over the course of those 52 million individual shifts,
    and how many rest breaks had been missed. Among other things, this undertaking
    required calculating numbers for the period from February 2001 to 2006, during which
    time actual rest break data was no longer available, due to the 2001 change in Wal-
    Mart’s policy that eliminated the requirement for employees to clock out and clock back
    in at the beginning and end of rest breaks. Dr. Baggett explained that his method for
    extrapolating the total amount of breaks that had been missed but unrecorded included
    (continuedK)
    Clock Punch Exception Reports” showed missed, inadequate, or overly-long breaks for
    all employees. These business records were used by Wal-Mart primarily for purposes
    of calculating payroll, and were analyzed by Appellees’ experts. At the class-
    certification stage, Dr. Baggett testified that he had analyzed some 24,000 individual
    employee work shifts in twelve Pennsylvania Wal-Mart stores between March 1998 and
    December 2000, and had concluded that some 40% of hourly workers had not received
    the number or duration of rest breaks to which they had been entitled. Dr. Baggett
    stated that his analysis squared with the results of the Shipley Audit. In challenging
    class certification, Wal-Mart presented the deposition testimony of its own expert to
    explain that the evidence relied upon by Appellees’ experts to show missed breaks was
    not reliable because an employee’s failure to clock out and clock back in from any given
    break did not necessarily indicate that the employee had failed to take a break. In
    certifying the class, the trial court ruled that “the discrepancies in testimony [regarding
    the accuracy/reliability of the business records] will undoubtedly be an issue for jury
    determination at trial.” Trial Court Opinion, 12/27/05, at 11.
    [J-43A&B-2013] - 7
    baseline calculations of the number of known, recorded missed breaks that had
    occurred prior to the 2001 change in rest break time clock policy. Based on these
    extrapolations, coupled with the average rate of pay for hourly Wal-Mart employees, all
    of which had been calculated within a reasonable degree of statistical certainty, Dr.
    Baggett testified that the total damages to Wal-Mart hourly employees for missed rest
    breaks during the relevant time period had been $68,412,107. Dr. Baggett also testified
    that, although he could not tell from the data why any individual rest break had been
    missed, he presumed rest breaks had not been missed voluntarily because Wal-Mart’s
    policy prohibited employees from missing or working through scheduled rest breaks.
    Dr. Shapiro testified for Appellees regarding off-the-clock work.      Dr. Shapiro
    stated that he had compared the Wal-Mart time clock, payroll, and rest break computer
    databases, and found numerous recorded instances of employees actively logged in to
    cash registers or computer-based learning terminals during times when they had
    simultaneously been clocked out for a break or had been clocked out of a shift
    altogether. He added that the total amount of such off-the-clock work hours decreased
    significantly after Wal-Mart instituted its “lock-out” policy in 2003. Dr. Shapiro had been
    provided with time clock and cash register log-in data for sixteen Pennsylvania Wal-Mart
    stores for the period from 2001 to 2006. In his testimony, Dr. Shapiro explained how he
    had extrapolated from that data to determine the average total number of hours of off-
    the-clock work performed by all hourly employees at all Pennsylvania Wal-Mart stores
    during the period from 1998 to 2005. He calculated that the unpaid earnings for all Wal-
    Mart employees working off-the-clock during the relevant period was $2,993,063.32,
    and testified that his computation had been formulated within a reasonable degree of
    statistical certainty.
    [J-43A&B-2013] - 8
    Appellees also presented the expert testimony of organizational psychologist and
    statistician, Frank Landy, Ph.D., who testified that Wal-Mart had promised all its
    employees, through a variety of means, that paid breaks were a benefit of employment
    with Wal-Mart, and that its employees understood and expected that all breaks were to
    be paid breaks. In discussing the Shipley Audit, Dr. Landy testified that Wal-Mart stores
    had used daily “time adjustment slips” to correct known rest break violation errors. He
    explained: “Adjustment means that the associate actually comes in and says, no, no, I
    actually did get my break; I just forgot to swipe in [and] out for [it].” Dr. Landy testified
    that only approximately 10% of the total number of rest break violations had been
    corrected through time adjustment slips, which led him to the conclusion that “the
    magnitude of this problem even after they correct it for honest mistakes is big.” See
    Braun, 
    24 A.3d at 932
     (quoting Dr. Landy’s trial testimony). 7
    7
    Dr. Landy also testified, inter alia, that Wal-Mart store managers earned significant
    year-end bonuses for maximizing profits, the key to which was keeping payroll costs
    down by intentionally understaffing their stores and forcing employees to miss breaks
    and work off-the-clock. He opined that a store manager could earn a $1300 annual
    bonus by simply shaving one minute per week per employee from a store’s payroll
    obligation. He further explained that if a manager could shave one hour per week per
    employee from a store’s payroll obligation, the annual bonus would be $82,000. The
    Superior Court summarized Dr. Landy’s testimony as follows:
    Dr. Landy also discussed understaffing in Wal–Mart stores.
    He opined that Wal–Mart's “preferred scheduling” program
    was the “root cause” of understaffing in the stores. There is
    a correlation, Dr. Landy stated, between understaffing and
    employees’ ability to receive breaks: the more understaffed
    the stores, the greater the pressure on managers not to
    provide breaks and on employees not to take breaks. He
    explained how the pressure to reduce payroll costs led to
    understaffing. Dr. Landy noted that the Wal–Mart store-
    manager-bonus system had a “negative effect” on
    compliance with Wal–Mart's policies on breaks and pay.
    Lastly, Dr. Landy testified that after Wal–Mart conducted its
    (Kcontinued)
    [J-43A&B-2013] - 9
    Appellees also presented the testimony of a number of former and current Wal-
    Mart employees, who testified that they had regularly been forced to work without taking
    breaks (or to take shortened breaks) because the stores in which they worked were
    chronically understaffed. In response, Wal-Mart presented the testimony of a number of
    current and former employees (all of whom had opted out of the class), who testified
    that they had never been forced to miss a rest break and had always been paid for the
    breaks they did take.
    During the defense case, Dr. Denise Martin, an expert statistician, testified that
    she had identified a number of alleged errors in the methods used by Appellees’ experts
    to arrive at their estimated damages computations. Principally, Dr. Martin took issue
    with Dr. Baggett’s premise that an employee’s failure to clock out and clock back in from
    a rest break indicated a missed rest break, as well as his conclusion that no missed
    breaks were voluntary. In Dr. Martin’s opinion, Dr. Baggett had used “bad” data to
    account for missing data, which is “statistically improper.” With respect to Dr. Shapiro’s
    methodology, Dr. Martin criticized his assumption that cashiers did not routinely log in to
    cash registers under another employee’s name. On this basis, Dr. Martin testified that
    (continuedK)
    Shipley Audit, Wal–Mart eliminated the requirement that
    employees punch the time clock for rest breaks; he opined
    that Wal–Mart eliminated “smoking gun” evidence of its
    policy violations to limit its liability.
    Braun, 
    24 A.3d at 887
     (citations to record and footnotes omitted).
    In contrast, Wal-Mart’s retail expert, Wade Fenn, testified that there was no link
    between Wal-Mart’s managers’ bonus compensation program and rest breaks, that
    Wal-Mart’s practices were consistent with other big-box retailers, and that Dr. Landy’s
    testimony regarding hypothetical year-end bonuses had been based on an erroneous
    comparison of employee hours to store profitability.
    [J-43A&B-2013] - 10
    Dr. Shapiro’s comparisons of time clock data to cash register log-in data were improper
    and resulted in an erroneous calculation of the number of hours of off-the-clock work
    that had occurred during the relevant time period.
    In this appeal, Wal-Mart asserts that it was subjected to “trial by formula,” a
    practice disapproved by the United States Supreme Court in Wal-Mart Stores, Inc. v.
    Dukes, __ U.S. __, 
    131 S. Ct. 2541
     (2011), and Comcast Corp. v. Behrend, __ U.S. __,
    
    133 S. Ct. 1426
     (2013).     The Court notes that Wal-Mart’s formulation of the issue
    accepted for review focuses on the procedural conduct of the trial. Nevertheless, Wal-
    Mart argues that the class was improperly certified because Appellees failed to prove
    that questions of law and fact were common to the class, and that common questions
    predominated over individual issues.8
    8
    Specifically, Wal-Mart asserts that the trial court, in certifying the class, and the
    Superior Court in affirming class certification, disregarded the “individualized issues
    [that] included whether class members actually missed breaks or had them cut short;
    whether, if a class member missed a break, his or her actions were voluntary; whether
    cashiers whose cash register log-in records did not match their time clock records
    actually worked off-the-clock; whether Wal-Mart intended to be contractually bound to
    each class member by the employment handbooks [promising paid breaks]; and
    whether each class member relied on the employee handbooks in deciding to work at
    Wal-Mart.” Appellants’ Brief at 28. The Court notes that an order granting class
    certification will not be disturbed on appeal unless the court abused its discretion in
    applying the procedural requirements for class certification. Samuel-Bassett v. Kia
    Motors Am., Inc., 
    34 A.3d 1
    , 15 (Pa. 2011). In deciding whether class action procedural
    requirements were misapplied or an incorrect legal standard was used in ruling on class
    certification, our standard of review is de novo and our scope of review is plenary. 
    Id.
    Wal-Mart’s allegation that both courts below disregarded individualized issues does not
    prove misapplication of procedural requirements because the existence of
    distinguishing individual facts among class members is not fatal to certification. Id. at
    23. Appellees here were not required to prove that the claims of all class members
    were identical. Class members may assert a single common complaint even if they
    have not all suffered actual injury, and demonstrating that all class members are subject
    to the same harm will suffice. Id. (citing Liss & Marion, P.C. v. Recordex Acquisition
    Corp., 
    983 A.2d 652
    , 666 (Pa. 2009)). For this reason, we do not discern an abuse of
    discretion in the pre-trial certification decision.
    [J-43A&B-2013] - 11
    In effect, Wal-Mart’s arguments in support of its assertion that the class should
    not have been certified mirror its arguments in support of the assertion that it was
    subjected to a trial by formula.    Nevertheless, the focus in this appeal should be
    primarily on the proofs offered at trial and whether the proceeding conducted by the trial
    court amounted to a trial by formula that relieved Appellees of their burden to produce
    common evidence on key elements of their claims.9 Our review of this question of law
    is plenary and de novo. Lower Makefield Twp. v. Lands of Dalgewicz, 
    67 A.3d 772
    ,
    775 (Pa. 2013).
    In response, Appellees argue that on the merits, class certification was warranted
    here, and that Wal-Mart was not subjected to a trial by formula, but rather was faced
    with a recognized and acceptable style of class action known as “replicated proof,” in
    which the same underlying evidence, if relevant and credible, proves each class
    member’s claim as if each class member had proceeded alone. Appellees’ Brief at 18
    (citing Liss & Marion v. Recordex Acquisition Corp., 
    983 A.2d 652
     (Pa. 2009)). In a

    retail associations, and a group of national, state, and local chambers of commerce.

    Due process in legal proceedings requires an opportunity to confront and cross-
    examine adverse witnesses.       Goldberg v. Kelly, 
    397 U.S. 254
    , 269-70 (1970).           As
    observed by the United States Court of Appeals for the Third Circuit, the validity of an
    argument challenging the manner in which a trial has been conducted and alleging that
    it was so highly prejudicial so as to amount to a denial of due process must be
    measured against the background of the trial as a whole; the complexity of the litigation;
    the length of the trial; the quantity of evidence received; and, the difficulty of the task
    that confronted the factfinder. Citron v. Aro Corp., 
    377 F.2d 750
    , 752 (3d Cir. 1967).
    The class action mechanism is designed to permit a named individual to proceed to trial
    on behalf of the class, including him- or herself, and to try all of the class members’
    claims together to judgment. Samuel-Bassett, 34 A.3d at 34 (citing Pa.R.C.P. 1715(c)).
    The United States Supreme Court's disapproval of “trial by formula” in Dukes was
    directed at a plan to try a sample set of class members’ claims of sex discrimination
    and, if discrimination was found and the claims were meritorious, to then multiply the
    average back-pay award to determine the class-wide recovery without further
    individualized proceedings. Dukes, __ U.S. at __, 
    131 S. Ct. at 2561
    . To the High
    Court, this “novel” process would have robbed Wal-Mart (in that case) of its right to
    litigate its defenses to individual claims, because liability for all but the sample set would
    never be tried.    
    Id.
       The United States Court of Appeals for the Sixth Circuit has
    described the “trial by formula” method disapproved in Dukes as follows:
    Dukes proposed a “Trial by Formula” process. Under this
    system, the district court would appoint a master to
    determine whether and how much backpay was due to a
    sample set of class members. The court would then multiply
    the total number of class members by the percentage of
    claims the special master determined were valid. Next, it
    would multiply that number by the average backpay award
    for sample claimants with a valid claim to determine the
    [J-43A&B-2013] - 13
    class’s recovery. The Court did not make clear whether
    Dukes proposed that the class’s recovery would be
    distributed pro rata, whether there would be some sort of
    claims procedure, based on the particular applicant’s date of
    non-promotion, or whether class counsel would dispose of
    the money through a cy pres distribution. Regardless, the
    Court held that the Trial by Formula approach would violate
    the Rules Enabling Act because it would abridge or modify
    Wal–Mart's right to present affirmative defenses to individual
    backpay determinations. Dukes, 
    131 S.Ct. at 2561
    .
    Davis v. Cintas Corp., 
    717 F.3d 476
    , 486 n.2 (6th Cir. 2013).
    Similarly, a Magistrate Judge of the United States District Court for the Southern
    District of New York described the “trial by formula” method disapproved in Dukes in the
    following terms:
    Specifically, the Supreme Court rejected a “Trial by
    Formula,” in which the plaintiffs would hold a trial for a
    sample set of class members’ claims of sex discrimination
    and then multiple the average backpay award to determine
    the class-wide recovery without further individualized
    proceedings. Under this proposal, Wal–Mart would have
    been denied its right to litigate its defenses to individual
    claims of discrimination, as liability for all but the sample set
    would have never been tried. Chipotle contends that Dukes
    requires individualized discovery of opt-in plaintiffs so that it
    can litigate its individualized defenses, and that the denial of
    this information might, in fact, render certification
    inappropriate.
    ***
    In Dukes, the Supreme Court focused on the need for a
    common contention that is capable of class-wide resolution:
    “Without some glue holding the alleged reasons [behind all
    of Wal–Mart's individual employment] decisions together, it
    will be impossible to say that examination of all the class
    members' claims for relief will produce a common answer to
    the crucial question why was I disfavored.” Dukes, 
    131 S.Ct. at 2552
     (emphasis in original).
    [J-43A&B-2013] - 14
    Scott v. Chipotle Mexican Grill, Inc., 
    300 F.R.D. 188
    , 191 (S.D.N.Y. 2014) (citations and
    quotation marks omitted).
    In this case, contrary to Wal-Mart’s assertions, the now-disapproved “trial by
    formula” process at issue in Dukes was not at work here, because there was no initial or
    prior adjudication of Wal-Mart’s liability to a subset of employees that would then be
    extrapolated to the rest of the class.    Instead, the extrapolation evidence Wal-Mart
    challenges in this appeal involves the amount of damages to the class as a whole. By
    contrast, the evidence of Wal-Mart’s liability to the entire class for breach of contract
    and WPCL violations was established at trial by presentation of Wal-Mart’s own
    universal employment and wage policies, as well as its own business records and
    internal audits. These records were sufficient to support the factfinder’s determination
    that there was an extensive pattern of discrepancies between the number and duration
    of breaks earned and the number and duration of breaks taken. Both parties had ample
    opportunity to present evidence to explain these discrepancies, i.e., to show that the
    discrepancies were or were not evidence of class-wide wage-and-hour violations. Thus,
    Wal-Mart’s claim that it was denied due process fails.
    Also, in Dukes, the class-action was brought for alleged violations of Title VII of
    the Civil Rights Act of 1964, and specifically alleged sexual discrimination in the hiring
    and promotion of female workers. The evidence in Dukes showed that Wal-Mart had an
    express policy prohibiting sex discrimination. Importantly, although some Wal-Mart
    managers applied their own subjective gender biases in making hiring and promotion
    decisions, some did not.      Thus, the High Court ruled that the element of class
    commonality was lacking because the required showing of “significant proof” that Wal-
    Mart operated under a “general policy of discrimination” was “entirely absent.” Dukes,
    __ U.S. at __, 
    131 S.Ct. at 2553
    . The Court noted that the expert opinion evidence of a
    [J-43A&B-2013] - 15
    “general policy of discrimination” offered by the plaintiffs could not assess “whether 0.5
    percent or 95 percent of the employment decisions at Wal-Mart might be determined by
    stereotyped thinking.” 
    Id.
    In this case, where systemic wage-and-hour violations were asserted, evidence
    was presented by appellees that, if believed, supported an inference that Wal-Mart
    managers company-wide were pressured to increase profits and decrease payroll by
    understaffing stores through the preferred scheduling system, and that these factors,
    including the managers’ annual bonus compensation program, impeded the ability of
    employees, across the board, to take scheduled, promised, paid rest breaks. The lack
    of proof of class commonality present in Dukes is not present here.
    Turning to Comcast v. Behrend, which Wal-Mart also cites here, the question for
    review before the High Court in that case was “[w]hether a district court may certify a
    class action without resolving whether the plaintiff class had introduced admissible
    evidence, including expert testimony, to show that the case is susceptible to awarding
    damages on a class-wide basis.” __ U.S. at __, 
    133 S. Ct. at
    1431 n.4. In that matter,
    two million Comcast customers comprised the class alleging various antitrust violations.
    The Court noted that both the U.S. District Court for the Eastern District of Pennsylvania
    and the U.S. Court of Appeals for the Third Circuit had perceived no need for the
    plaintiffs to “tie each theory of antitrust impact” to a calculation of damages. 
    Id.
     at __,
    
    133 S.Ct. at 1433
    .    The Court determined that the District Court and the Court of
    Appeals had entirely ignored the “first step” of a “damages study,” which requires “the
    translation of the legal theory of the harmful event into an analysis of the economic
    impact of that event.”

    133 S.Ct. at 1435
     (italics in original) (citing Federal
    Judicial Center Reference Manual on Scientific Evidence 432 (3d ed. 2011). Because
    the damages methodology used in Behrend identified damages that were not the result
    [J-43A&B-2013] - 16
    of the specific antitrust violation for which the class had been certified, the High Court
    reversed the order upholding the class certification. 
    Id.
     at __, 
    133 S.Ct. at 1434-35

    The Behrend Court, did, however, recognize that where a theory of liability is
    capable of class-wide proof, calculations of damages need not be exact. 
    Id.
     at __, 
    133 S.Ct. at 1433-34
    . Indeed, as one federal district court has noted, one takeaway from
    the Supreme Court’s decisions in this area is that “the propriety of class certification in
    wage and hour cases that involve recordkeeping violations should be assessed in light
    of the relaxed burden of proving damages.” Gomez v. Tyson Foods, Inc., 
    295 F.R.D. 397
    , 400 (D. Neb. 2013) (citing Behrend and Dukes). It is also well-settled that when an
    employer fails to keep complete records of hours, employees may prove their hours
    through representative testimony. Anderson v. Mt. Clemens Pottery Co., Inc., 
    328 U.S. 680
    , 688 (1946), superseded by statute on other grounds. “[E]ven where the lack of
    accurate records grows out of a bona fide mistake as to whether certain activities or
    non-activities constitute work, the employer, having received the benefits of such work,
    cannot object to the payment for the work on the most accurate basis possible under
    the circumstances.” 
    Id.
     One federal Circuit Court has observed that “[a] rule preventing
    employees from recovering for uncompensated work because they are unable to
    determine precisely the amount due would result in rewarding employers for violating
    federal [and state] law.” Reich v. Southern New England Telecomms. Corp., 
    121 F.3d 58
    , 69 (2d Cir. 1997) (citing Mt. Clemens, 
    328 U.S. at 687
    ).
    Unlike the plaintiffs in Behrend, who failed to translate the legal theory of their
    harm into an analysis of its economic impact, Appellees here offered data and analysis
    from Wal-Mart’s own business records, including time clock and cashier log-in data, to
    support their claim of damages related to systemic wage and hour violations. Wal-Mart
    responds now, as it did at trial and on direct appeal, that the time clock and cash
    [J-43A&B-2013] - 17
    register log-in data do not necessarily reflect that breaks were missed or shortened.
    Nevertheless, by advancing this argument, Wal-Mart impliedly acknowledges that its
    record-keeping has been incomplete, and it cannot now avoid the relaxed burden of
    proving damages through extrapolation. Mt. Clemens.
    The essence of Wal-Mart’s appeal is its assertion that the class-action device, in
    this instance, had “run amok,” resulting in a “trial by formula” during which Appellees’
    requirement to prove the essential elements of their claims as to each class member
    was eliminated. Appellants’ Brief at 18. Indeed, Wal-Mart seems to suggest that the
    class claims of breach of contract and unjust enrichment could only be properly proven
    by an individual examination of the 187,979 class members to determine whether each
    had been promised paid breaks that they were then forced to miss, or partially work
    through, and whether each had, or had not, been forced to work off-the-clock.
    Relatedly, Wal-Mart suggests that any determination of damages is only proper on an
    individual class member basis, and that any tabulation of damages across-the-board
    would violate due process. The Court disagrees.11
    There was a single, central, common issue of liability here: whether Wal-Mart
    failed to compensate its employees in accordance with its own written policies. On that
    question, both parties presented evidence. Wal-Mart’s liability was proven on a class-
    wide basis. Damages were assessed based on a computation of the average rate of an
    11
    We are persuaded by the observation of the federal district court in Jackson v.
    Bloomberg, 
    298 F.R.D. 152
    , 168 (S.D.N.Y. 2014), which declined to read into Behrend
    “a principle that would fundamentally undermine the use of the class action vehicle in
    the wage-and-hour context.” In addition, we subscribe to what appears to be the
    prevailing view that Dukes does not bar class actions in wage and hour cases. See
    Ensor v. Chipotle Mexican Grill, Inc., 
    300 F.R.D. 188
    , 191 (S.D.N.Y. 2014) (“The weight

    cases.”); Morris v. Affinity Health Plan, Inc.,
