    v.                                                          (Super. Ct. No. 37-2007-00069288-

    SHARP HEALTHCARE et al.,
    Defendants and Respondents.
    APPEAL from an order of the Superior Court of San Diego County, Ronald S.
    Prager, Judge. Affirmed.

    Appellants.
    Littler Mendelson, Theodore R. Scott and Jody A. Landry for Defendants and
    Respondents.
    Before us for a second time is a proposed class action brought by Juan Marcos
    Almaraz, Susan K. Bowers, Ruth Donley, Carolyn M. Hitchin, Beth Hurley, Kurt Kalker,
    Lois K. Klepin and Maureen C. Schickler (Plaintiffs), alleging violations of state wage
    and hour laws against Sharp HealthCare, Grossmont Hospital Corporation, Sharp Chula
    Vista Medical Center, Sharp Memorial Hospital and Sharp Coronado Hospital and
    Healthcare Center (collectively "Sharp") on behalf of a proposed class comprised of
    Sharp's registered nurses (RN's). When this action was originally before us in 2010, we
    reversed the trial court's order denying class certification and remanded with instructions
    that the trial court reconsider the class certification motion to address additional theories
    of liability asserted by Plaintiffs.1 On remand, the trial court reconsidered and denied the
    motion for class certification, and Plaintiffs now appeal from that order.
    As we will explain, we conclude that the trial court was within its discretion to
    deny the motion for class certification, and we accordingly affirm the trial court's order.
    I
    FACTUAL AND PROCEDURAL BACKGROUND
    A.     Allegations of the Complaint
    As set forth in the 2010 opinion, Plaintiffs are RN's who work or worked at health
    care facilities operated by Sharp. In June 2007, Plaintiffs filed a class action complaint
    on behalf of a proposed class defined as "[a]ll non-exempt [RN's] currently or formerly
    employed by Sharp HealthCare in the County of San Diego at one of its affiliated health
    1     Our previous opinion in this matter was Almaraz v. Sharp HealthCare, D055739
    (Nov. 16, 2010) [nonpub. opn.] (the 2010 opinion).
    2
    care institutions on or after June 28, 2003." The complaint contained four causes of
    action.
    The first cause of action alleged that Sharp had failed to pay wages for all time
    worked in violation of Labor Code sections 204 and 1194. Specifically, the complaint
    alleged that (1) RN's were not paid for time worked before or after scheduled shifts; and
    (2) that although RN's worked through meal periods, half-hour meal periods were
    deducted from their wages.
    The second cause of action alleged that Sharp failed to provide RN's with
    30-minute meal periods relieved of all duties, in violation of Labor Code section 226.7
    and section 11 of Industrial Welfare Commission Wage Order No. 5-2001 (see Cal. Code
    Regs., tit. 8, § 11050, subd. 11).2
    2       Labor Code section 226.7 provides: "(a) No employer shall require any employee
    to work during any meal or rest period mandated by an applicable order of the Industrial
    Welfare Commission. [¶] (b) If an employer fails to provide an employee a meal period
    or rest period in accordance with an applicable order of the Industrial Welfare
    Commission, the employer shall pay the employee one additional hour of pay at the
    employee's regular rate of compensation for each work day that the meal or rest period is
    not provided."
    "The Industrial Welfare Commission [(IWC)] . . . is the state agency empowered
    to formulate wage orders governing employment in California." (Murphy v. Kenneth
    Cole Productions, Inc. (2007) 
    40 Cal.4th 1094
    , 1102, fn. 4.) With respect to meal
    periods, the applicable wage order provides in relevant part: "(A) No employer shall
    employ any person for a work period of more than five (5) hours without a meal period of
    not less than 30 minutes, except that when a work period of not more than six (6) hours
    will complete the day's work the meal period may be waived by mutual consent of the
    employer and the employee. Unless the employee is relieved of all duty during a 30
    minute meal period, the meal period shall be considered an 'on duty' meal period and
    counted as time worked. An 'on duty' meal period shall be permitted only when the
    nature of the work prevents an employee from being relieved of all duty and when by
    written agreement between the parties an on-the-job paid meal period is agreed to. The
    3
    The third cause of action alleged that Sharp failed to provide RN's with 10-minute
    rest periods relieved of all duties in violation of Labor Code section 226.7 and section 12
    of Industrial Welfare Commission Wage Order No. 5-2001 (Cal. Code Regs., tit. 8,
    § 11050, subd. 12).
    The fourth cause of action alleged a violation of the unfair competition law (Bus.
    & Prof. Code, §§ 17200-17209) (the UCL) premised on Sharp's alleged violations of the
    state wage and hour laws.
    B.     The Original Class Certification Motion and Our 2010 Opinion
    Plaintiffs filed their original motion for class certification in April 2009. As we
    explained in the 2010 opinion, Plaintiffs' class certification motion was unfocused, and
    thus did not clearly and logically set forth the basis for Plaintiffs' claim that — despite
    Sharp's stated policies — RN's did not in fact receive required rest and meal periods or
    the appropriate compensation in lieu of those meal and break periods. In opposing class
    written agreement shall state that the employee may, in writing, revoke the agreement at
    any time. [¶] (B) If an employer fails to provide an employee a meal period in
    accordance with the applicable provisions of this order, the employer shall pay the
    employee one (1) hour of pay at the employee's regular rate of compensation for each
    workday that the meal period is not provided." (Cal. Code Regs., tit. 8, § 11050,
    subd. 11(A)-(B).) Specifically with respect to health care workers, the wage order
    provides: "(D) Notwithstanding any other provision of this order, employees in the
    health care industry who work shifts in excess of eight (8) total hours in a workday may
    voluntarily waive their right to one of their two meal periods. In order to be valid, any
    such waiver must be documented in a written agreement that is voluntarily signed by both
    the employee and the employer. The employee may revoke the waiver at any time by
    providing the employer at least one (1) day's written notice. The employee shall be fully
    compensated for all working time, including any on-the-job meal period, while such a
    waiver is in effect." (Cal. Code Regs., tit. 8, § 11050, subd. 11(D).)
    4
    certification, Sharp correctly observed that Plaintiffs' allegations were difficult to
    understand, but it attempted to summarize those allegations as follows:
    "Sharp admits finding it difficult to ascertain from Plaintiffs[']
    [memorandum of points and authorities] the basis for Plaintiffs' contention
    that the meal/rest period and off the clock claims of all [RN's] can be
    resolved through common proof. . . . That being said, it appears that
    Plaintiffs' primary theory is that [RN's] are denied meal/rest periods
    because their Units will be out of compliance with staffing ratios if they
    take them ('Ratio Theory'). Secondarily, Plaintiffs appear to contend that
    [RN's] working 12[-]hour shifts do not understand that they are entitled to
    three 10[-]minute breaks per shift and therefore are denied a third break
    every day they work ('Confusion Theory'), and that [RN's] do not put
    down all time worked on their timecards and do not record NB even when
    they do not get meal/rest periods, because they have been intimidated into
    not doing so by their supervisors ('Coercion Theory')."
    In the 2010 opinion, we adopted the terms "Ratio Theory," "Confusion Theory"
    and "Coercion Theory" to describe Plaintiffs' theories of liability.
    In ruling on the original motion for class certification, the trial court discussed the
    Ratio Theory, Confusion Theory and Coercion Theory, and decided that none of them
    were appropriate for class treatment because common questions of law and fact did not
    predominate and because Plaintiffs had not met their burden to show that the case could
    be managed on a class basis. As relevant to the issues we will discuss below, the trial
    court explained that common questions of law and fact did not predominate for the
    Confusion Theory because it was "based on generalized assumptions which are premised
    upon subjective analysis of each individual's state of mind." The trial court stated,
    "Furthermore, there is likely a lack of any substantial commonality since there are over
    100 different managers with various hospitals/facilities. An analysis of the states of mind
    of nurses deposed has led this Court to conclude that Plaintiffs have not met their burden
    5
    of presenting substantial evidence to support these theories. There is a complete lack of
    consensus covering a broad range of highly individualized responses with respect to meal
    and rest breaks. . . . Where coercion and confusion is claimed, the responses are highly
    subjective and would require individualized examination to reconcile the disparities on
    the time card, prepared while the information was fresh in each nurse['s] mind. Also,
    each nurse would have to explain his or her departure from legal requirements." The trial
    court separately explained that Plaintiffs had failed to meet their burden to establish that
    the case would be manageable as a class action in light of the fact that "[t]hey have
    lumped together approximately 3[,]900 nurses working for over 100 managers in 164
    units."
    In the 2010 opinion, we did not specifically address whether the trial court was
    within its discretion to decide that the Ratio Theory, Confusion Theory and Coercion
    Theory were inappropriate for class treatment. Instead, we concluded that the trial court
    abused its discretion because it had not considered whether class treatment was
    appropriate as to two additional theories of liability that Plaintiffs described in their
    briefing of the motion for class certification and were consistent with the allegations of
    Plaintiffs' complaint. Those theories were (1) the claim that Sharp acted unlawfully in
    requiring that RN's working over eight hours agree to sign forms waiving either their first
    or second meal period; (2) the claim that RN's were not receiving appropriate overtime
    6
    pay for educational, training and orientation activities designated by the code "EDUC."3
    We remanded "for the trial court to reconsider the motion, taking into account Plaintiffs'
    additional theories of liability, as expressed in their class certification motion, premised
    on (1) the meal waiver forms, and (2) the failure to pay overtime for activities coded as
    'EDUC.' " For the benefit of the trial court on remand, the 2010 opinion also addressed
    Plaintiffs' challenge to several evidentiary rulings made by the trial court, concluding that
    most of the challenged rulings were proper, with the exception of the trial court's
    exclusion of certain statements in the Plaintiffs' declarations.
    C.     Proceedings on Remand
    On remand, the parties entered into a stipulation regarding the scope of the trial
    court proceedings required by the 2010 opinion, which stated that "[t]he parties agree that
    the Court is to reconsider Plaintiff's motion for class certification taking into account
    every theory of liability advanced by Plaintiffs, including Plaintiffs' two additional
    theories of liability . . ." (i.e., the EDUC/Overtime Theory and Meal Waiver Theory), and
    "taking into account all admissible evidence."
    Plaintiffs then filed a memorandum of points and authorities in support of a
    "reconsidered motion for class certification" (Plaintiffs' reconsidered motion). Although
    Plaintiffs' reconsidered motion is somewhat unfocused, it discusses the EDUC/Overtime
    3     In their briefing of the current appeal, Plaintiffs have referred to these theories as
    the "EDUC/Overtime Theory" and the "Meal Waiver Theory." We will follow the same
    convention.
    7
    Theory, the Meal Waiver Theory, and the complaint's UCL cause of action, arguing that
    those theories are suitable for class treatment.4
    Plaintiffs' reconsidered motion clarified that the Meal Waiver Theory was based
    on the allegation that the IWC lacked the authority to issue section 11(D) of Wage Order
    No. 5, which states that employees in the healthcare industry "who work shifts in excess
    of eight (8) total hours in a workday may voluntarily waive their right to one of their two
    meal periods." (Ibid.) According to Plaintiffs, section 11(D) of Wage Order No. 5 is
    void because it conflicts with Labor Code section 512, subdivision (a), which provides
    that "if the total work period per day of the employee is no more than six hours, the meal
    period may be waived by mutual consent of both the employer and employee." (Ibid.)
    Plaintiffs' reconsidered motion also argued that despite the trial court's prior
    decision that class treatment was not appropriate for the Confusion Theory, the court
    should certify a class as to the UCL cause of action based on a similar concept as the
    Confusion Theory. Plaintiffs argued that class certification was proper as to what it
    refers to in its appellate briefing as a "Confusion Theory through a UCL lens" on the
    purported basis that — in a claim brought under the UCL — "proof of an unlawfully
    deceptive practice as to one class member allows an inference of reliance as to all,"
    limiting the number of individual issues that would have to be decided.
    4      Plaintiffs explain in their appellate briefing that on "remand, Plaintiffs abandoned
    their Ratio and Coercion Theories."
    8
    Regarding the EDUC/Overtime Theory, Plaintiffs' reconsidered motion stated that
    although the trial court had excluded evidence relating to that theory in ruling on the
    original class certification motion, Plaintiffs proposed to provide "additional evidence"
    on that issue in connection with the reconsidered motion. However, as Sharp pointed out
    in its opposition, that "additional evidence" was the same evidence that the trial court has
    already excluded in connection with the original class certification motion.
    In a lengthy minute order, the trial court denied Plaintiffs' reconsidered motion.
    After thoroughly and accurately setting forth the legal standards governing class
    certification, the trial court separately discussed whether class treatment was appropriate
    for the three different theories of liability covered in Plaintiffs' reconsidered motion.
    As to the "Confusion Theory through a UCL lens,"5 the trial court noted that the
    UCL theory was not one of the two theories that the 2010 opinion instructed it to consider
    on remand, and it pointed out that Plaintiffs had cited no persuasive authority to support
    their argument that the trial court should consider new theories of liability. However, the
    trial court nevertheless reached the merits of whether the Confusion Theory through a
    UCL lens was suitable for class treatment. The trial court concluded that based on
    "admissible evidence presented to the court, . . . Plaintiff failed to establish a certifiable
    5       The trial court did not employ this phrase to describe Plaintiffs' new theory of
    liability under the UCL, as it was used by Plaintiffs for the first time in their appellate
    briefing. We use the term here because it is a good description of Plaintiffs' theory, and
    in shorthand we will refer to the theory as the "UCL Theory."
    9
    class" based on that theory, or any of "the theories presented in the original motion or
    theories that may be derived from said theories."
    In addressing the Meal Waiver Theory, the trial court set forth alternative bases for
    denying class certification. First, it determined that the Meal Waiver Theory failed on the
    merits because Labor Code section 512, subdivision (b) "specifically authorized [the
    IWC] to enact an exception to the general requirements of section 512, subd[ivision] (a)."
    The trial court also explained that "[e]ven if the Court were to consider the IWC's wage
    order invalid, Plaintiffs still failed to establish the prerequisites of ascertainability,
    commonality, and typicality . . . ." Specifically, the court stated that (1) the class was
    overbroad and unascertainable because the "parties agree that waiver forms do not apply
    to approximately 30 percent of the RN[']s"; (2) individual issues would predominate
    because establishing whether a class member was harmed would require an
    individualized inquiry into whether the RN's self-scheduled their meals or already
    received a premium payment for a specific day of work by including the "NB" code on
    their timecards; and (3) Plaintiffs had not established the manageability of litigating the
    Meal Waiver Theory as a class action, in that Plaintiffs did not put forth a specific trial
    plan and instead "merely informed the Court of tools it may use to test the viability of
    their theories." (Italics omitted, underscoring added.)
    With respect to the EDUC/Overtime Theory, the trial court explained that because
    Plaintiffs had submitted no admissible evidence regarding that theory, the court had no
    basis for concluding that any of the requirements for class treatment had been met.
    10
    II
    DISCUSSION
    A.     Applicable Legal Standards
    The legal standards that we set forth in the 2010 opinion continue to apply, and we
    restate them here.
    1.     Standard of Review for Challenge to Order Denying Class Certification
    "[T]rial courts are ideally situated to evaluate the efficiencies and practicalities of
    permitting group action" and are accordingly "afforded great discretion in granting or
    denying certification." (Linder v. Thrifty Oil Co. (2000) 
    23 Cal.4th 429
    , 435 (Linder)
    435.) We thus apply an abuse of discretion standard of review to an order denying class
    certification. (Sav-On Drug Stores, Inc. v. Superior Court (2004) 
    34 Cal.4th 319
    , 326
    (Sav-On).) "A certification order generally will not be disturbed unless (1) it is
    unsupported by substantial evidence, (2) it rests on improper criteria, or (3) it rests on
    erroneous legal assumptions." (Fireside Bank v. Superior Court (2007) 
    40 Cal.4th 1069
    ,
    1089 (Fireside).) "Under this standard, an order based upon improper criteria or
    incorrect assumptions calls for reversal ' "even though there may be substantial evidence
    to support the court's order." ' [Citations.] Accordingly, we must examine the trial court's
    reasons for denying class certification. 'Any valid pertinent reason stated will be
    sufficient to uphold the order.' " (Linder, at p. 436.)
    2.     Requirements for Class Certification
    "Section 382 of the Code of Civil Procedure authorizes class suits in California
    when 'the question is one of a common or general interest, of many persons, or when the
    11
    parties are numerous, and it is impracticable to bring them all before the court.' " (Linder,
    supra, 23 Cal.4th at p. 435.) "Class certification requires proof (1) of a sufficiently
    numerous, ascertainable class, (2) of a well-defined community of interest, and (3) that
    certification will provide substantial benefits to litigants and the courts, i.e., that
    proceeding as a class is superior to other methods." (Fireside, 
    supra,
     40 Cal.4th at
    p. 1089.) "The party seeking certification has the burden to establish the existence of
    both an ascertainable class and a well-defined community of interest among class
    members." (Sav-On, 
    supra,
     34 Cal.4th at p. 326.) "The 'community of interest'
    requirement embodies three factors: (1) predominant common questions of law or fact;
    (2) class representatives with claims or defenses typical of the class; and (3) class
    representatives who can adequately represent the class." (Ibid.)
    The requirement that common questions of law and fact predominate " 'means
    "each member must not be required to individually litigate numerous and substantial
    questions to determine his [or her] right to recover following the class judgment; and the
    issues which may be jointly tried, when compared with those requiring separate
    adjudication, must be sufficiently numerous and substantial to make the class action
    advantageous to the judicial process and to the litigants." ' " (Lockheed Martin Corp. v.
    Superior Court (2003) 
    29 Cal.4th 1096
    , 1108.)
    The concept of manageability arises under the issue of whether a class action is
    superior to individual lawsuits. "[E]ven if questions of law or fact predominate, the lack
    of superiority provides an alternative ground to deny class certification. [¶] . . . [¶] In
    deciding whether a class action would be superior to individual lawsuits, ' the court will
    12
    usually consider [four factors]: [¶] [(1)] The interest of each member in controlling his
    or her own case personally; [¶] [(2)] The difficulties, if any, that are likely to be
    encountered in managing a class action; [¶] [(3)] The nature and extent of any litigation
    by individual class members already in progress involving the same controversy; [and]
    [¶] [(4)] The desirability of consolidating all claims in a single action before a single
    court.' " (Basurco v. 21st Century Ins. Co. (2003) 
    108 Cal.App.4th 110
    , 120-121, italics
    added (Basurco).) As our Supreme Court has commented, the proponent's burden of
    establishing the propriety of class certification "clearly contemplates a demonstration of
    predominance and manageability." (Washington Mutual Bank v. Superior Court (2001)
    
    24 Cal.4th 906
    , 922, italics added (Washington Mutual).)
    B.     The Trial Court Did Not Refuse to Consider the UCL Theory
    Plaintiffs' first contention is that the trial court abused its discretion because it
    improperly refused to consider whether class treatment was proper for the UCL Theory.
    According to Plaintiffs, the court refused to consider that issue because it decided, as a
    preliminary matter, that the scope of the issues specified for remand in the 2010 opinion
    did not include whether the class certification motion should be granted as to the UCL
    Theory.
    Plaintiffs' argument is easily rejected because its factual premise is faulty. As we
    have described, the trial court did not refuse to consider whether class treatment was
    appropriate for the UCL Theory. Instead, as an alternative basis for its ruling, the trial
    court reached the merits of the class certification issue and stated that Plaintiffs had failed
    to establish a certifiable class. Therefore, we reject Plaintiffs' contention that the trial
    13
    court erred by refusing to consider the merits of whether the UCL theory provided a
    suitable basis for class certification.6
    C.     The Trial Court Properly Refused to Consider the Evidence It Had Already Ruled
    Inadmissible to the Extent the 2010 Opinion Affirmed Those Rulings
    Plaintiffs next take issue with the trial court's refusal to consider certain evidence
    when ruling on Plaintiffs' reconsidered motion for class certification.
    As background to this issue, as we explained in the 2010 opinion, the trial court
    either struck or ruled inadmissible a significant portion of the evidence that Plaintiffs
    attempted to rely on to support the class certification motion. With respect to the
    evidence Plaintiffs submitted with their moving papers, the trial court excluded — among
    other things — several paragraphs of the declarations of two of Plaintiffs' expert
    witnesses and some of the paragraphs of the declarations filed by the named plaintiffs.
    Along with their reply memorandum, Plaintiffs attempted to file a supplemental
    declaration signed by their attorney, which attached 37 exhibits including the full
    transcripts from recently taken depositions of 10 RN's and over 600 pages of timecards
    and payroll reports from putative class members purporting to show "various categories
    of wage and hour violations." With the exception of certain impeachment evidence, the
    trial court granted Sharp's motion to strike the supplemental evidence that Plaintiffs
    6       Because the trial court did consider the merits of whether the UCL Theory was
    appropriate for class treatment, we need not, and do not, address Plaintiffs' contention
    that the trial court should have considered the UCL Theory on the ground that on remand
    the trial court was required to " 'consider afresh' " whether Plaintiffs satisfied the class
    action requirements on any theory, even those not explicitly set forth in our directions to
    the trial court in the 2010 opinion.
    14
    submitted with their reply memorandum. The 2010 opinion closely analyzed Plaintiffs'
    challenges to the trial court's evidentiary rulings, affirming all of them except for rulings
    excluding some of the paragraphs of the named plaintiffs' declarations.
    In its ruling on Plaintiffs' reconsidered motion, the trial court explained that it
    would not revisit its evidentiary rulings made in connection with its original ruling on the
    motion for class certification. The trial court specifically rejected Plaintiffs' argument
    that the stricken evidence previously submitted with the reply memorandum should now
    be admitted because it was being submitted as part of the initial moving papers for
    Plaintiffs' reconsidered motion. As the trial court explained, "The Court of Appeal
    recognized the relevance of the evidentiary issues raised by Plaintiffs on remand . . . and
    did a careful analysis of this Court's rulings. Plaintiffs' assertion that it may present
    evidence that this Court and the Court of Appeal found to be objectionable in this
    reconsidered motion to support their theories, i.e., evidence presented with the reply
    brief, disregards the Court of Appeal's recognition of the relevance of these rulings on
    remand and does not square with the time and attention that the Court of Appeal spent on
    the evidentiary aspect of the class certification motion."
    We agree with the trial court. In the 2010 opinion we directed the trial court to
    review the motion for class certification that Plaintiffs had already filed, with an explicit
    focus on the Meal Waiver Theory and EDUC/Overtime Theory. As the trial court
    correctly observed, we extensively discussed the evidentiary challenges raised by
    Plaintiffs in the 2010 appeal — including Plaintiffs' challenge to the exclusion of the
    evidence they filed with the reply memorandum — because we intended those
    15
    evidentiary rulings to remain in place during the trial court's reconsideration of the class
    certification motion. Plaintiffs' request that the trial court consider evidence that it
    already ruled inadmissible is contrary to our instructions in the 2010 opinion.
    In addition to contending that the trial court should have admitted the previously
    excluded evidence, Plaintiffs argue that the excluded evidence concerning the
    EDUC/Overtime Theory still should have played some role in the trial court's analysis of
    whether that theory was appropriate for class certification.
    As an initial matter, we note that the trial court's refusal to consider the evidence
    relating to the EDUC/Overtime Theory had a profound impact on Plaintiffs' case because
    the trial court's evidentiary rulings resulted in the exclusion of all of the evidence relating
    to whether class treatment was appropriate for the EDUC/Overtime Theory. Based on
    the complete lack of evidentiary support, the trial court concluded in ruling on Plaintiffs'
    reconsidered motion, that Plaintiffs had not met their burden with respect to the
    EDUC/Overtime Theory to establish the requirements for class certification.
    Focusing first on the evidence on the EDUC/Overtime Theory submitted with
    their moving papers for the class certification motion, Plaintiffs acknowledge that the
    trial court sustained Sharp's objections to the declaration and attached exhibit submitted
    by Plaintiffs' counsel, Robert Cantore. However, Plaintiffs argue that the trial court still
    should have considered that declaration and attached exhibit when deciding the class
    16
    certification motion, even though they were technically excluded from evidence.7
    Plaintiffs argue that although "the attorney's declaration was stricken as evidence . . . ,
    that does not mean that the declaration should not have been considered" to show that
    Cantore "had discovered evidence . . supporting Plaintiffs' EDUC/Overtime Theory . . . in
    Sharp's own payroll records." Next, focusing on the evidence on the EDUC/Overtime
    Theory submitted with the reply memorandum, Plaintiffs argue that even though it was
    stricken, that evidence nevertheless "should have been considered in assessing not
    whether Plaintiffs' claims have merit but whether they were susceptible to class
    treatment."
    The argument is nonsensical and we reject it. The point of the class certification
    motion was for Plaintiffs to establish that the requirements for class certification existed
    for the EDUC/Overtime claims and their other theories of liability. Plaintiffs submitted
    the evidence for that purpose, and the trial court excluded it. Plaintiffs have cited no
    authority, and we are aware of none, that would allow the court to consider excluded
    evidence for the limited purpose of ruling on a class certification motion. Without any
    7      Paragraph 6 of the declaration of Robert A. Cantore stated, "In addition to
    assembling documents and deposition transcripts, I also caused paralegals from my office
    to review the time cards produced by Defendants for the named plaintiffs. Attached
    hereto as Exhibit 3 is a true and correct copy of [a] spreadsheet prepared by my firm's
    paralegals showing how Defendants' systemwide Payroll Department incorrectly denied
    or miscalculated overtime compensation, often more than 50 percent of the time, in
    instances when the systemwide payroll code EDUC was applied to training, education,
    orientation or meetings recorded on the [sic] seven of the eight Plaintiffs' time cards."
    The trial court sustained Sharp's objection to that paragraph for lack of personal
    knowledge and to exhibit 3 referred to therein. Plaintiffs did not challenge that
    evidentiary ruling in their first appeal, and they do not challenge it now.
    17
    admissible evidence supporting its claim that each of the requirements for class
    certification existed for the EDUC/Overtime Theory of liability, the trial court properly
    denied class certification.
    D.     The Trial Court Was Within Its Discretion to Conclude That the Class Was
    Overbroad with Respect to the Meal Waiver Theory
    As one of the alternative bases for denying class certification on the Meal Waiver
    Theory, the trial court stated that "the class as defined is overbroad" because the parties
    agreed that "the waiver forms do not apply to approximately 30 percent of the RN[']s
    since they do not work shifts in excess of 10 hours." As the trial court explained, "[a]
    class cannot be certified when a proposed class is overbroad because a substantial portion
    of the class were never subjected to or damaged by the asserted illegal practice[,]" and
    "[a]s a result the class is unascertainable." Plaintiffs contend that the trial court's ruling
    on this issue was an abuse of discretion. As we will explain, we disagree.
    As an initial matter, we discuss the concept of overbreadth and ascertainability as
    it applies in class certification motions. As we have explained, "[t]he party seeking
    certification has the burden to establish the existence of . . . an ascertainable class . . . ."
    (Sav-On, supra, 34 Cal.4th at p. 326.) For a proposed class to be ascertainable, (1) the
    class definition must state precise and objective criteria that allow identification of
    persons who have claims and will be bound by the results of the litigation (Marler v.
    E.M. Johansing, LLC (2011) 
    199 Cal.App.4th 1450
    , 1459; Medrazo v. Honda of North
    Hollywood (2008) 
    166 Cal.App.4th 89
    , 101; Global Minerals & Metals Corp. v. Superior
    Court (2003) 
    113 Cal.App.4th 836
    , 858); and (2) there must be a way to identify those
    18
    persons and give them notice of the litigation without undue expense or time, usually by
    reference to official or business records (Archer v. United Rentals, Inc. (2011) 
    195 Cal.App.4th 807
    , 828; Sevidal v. Target Corp. (2010) 
    189 Cal.App.4th 905
    , 919
    (Sevidal)). "Courts have recognized that 'class certification can be denied for lack of
    ascertainability when [(1)] the proposed definition is overbroad and [(2)] the plaintiff
    offers no means by which only those class members who have claims can be [separated]
    from those who should not be included in the class.' " (Sevidal, at p. 921.)
    Here, the proposed class encompasses all non-exempt RN's employed by Sharp or
    its affiliates since June 28, 2003. As the trial court observed, approximately 30 percent of
    the RN's could not have been harmed by Sharp's use of meal waivers because they did
    not work shifts over 10 hours.8 On that basis, the trial court determined that the class
    was overbroad and therefore unascertainable. We agree. By broadly including all of
    Sharp's nonexempt RN's in the class — even the 30 percent who suffered no harm — the
    class definition did not describe "an identifiable group that was harmed by the defendant"
    (Akkerman v. Mecta Corp., Inc. (2007) 
    152 Cal.App.4th 1094
    , 1100, italics added), or " 'a
    set of common characteristics sufficient to allow a member of [the proposed class] to
    8       Plaintiffs state in their reply brief that they are not completely in agreement with
    the trial court's statement that waiver forms do not apply to the approximate 30 percent of
    RN's because those RN's work shifts shorter than 10 hours. Plaintiffs state that some of
    those RN's may have worked longer shifts at other times during the class period although
    they do not currently work a shift of that length. However, Plaintiffs state they are not
    able to estimate how many RN's would be in that position and would need to conduct
    further discovery on the issue.
    19
    identify himself or herself as having a right to recover based on the description.' "
    (Sevidal, supra, 189 Cal.App.4th at p. 920, italics added.)
    Plaintiffs contend that 30 percent is not a significant percentage of class members
    for the purpose of an ascertainability and overbreadth analysis. Plaintiffs rely on cases in
    which a class was determined to be overbroad when more than half of the class did not
    suffer injury. (Pfizer Inc. v. Superior Court (2010) 
    182 Cal.App.4th 622
    , 632 [in a case
    alleging deceptive advertising, the class was overbroad when "many, if not most, class
    members were not exposed" to the allegedly deceptive advertising campaign (italics
    added)]; Sevidal, supra, 189 Cal.App.4th at p. 921 [in a case alleging false advertising
    and similar claims, the class was overbroad when "approximately 80 percent" of the class
    members were never exposed to the alleged misrepresentation].) In our view Sevidal and
    Pfizer present outlying factual scenarios and do not stand for the general principle that a
    trial court lacks discretion to determine that a class is overbroad unless more than half of
    the class members suffered no harm. Instead of asking whether a majority of the class
    members lacked any injury, the more sensible inquiry is set forth in Bell v. Farmers Ins.
    Exchange (2004) 
    115 Cal.App.4th 715
    , 743, where the court inquired whether the
    unharmed class members represented only a "marginal element" in the class. Bell
    determined the class was not overbroad when a random sample showed that only
    5.7 percent of the employees in the random sample lacked an interest in the objectives of
    the litigation. (Ibid.) Similarly, the standard applied in Sevidal was whether the
    percentage of class members without any injury was "significant" rather than "only
    slightly overinclusive." (Sevidal, at p. 921.) Here, the percentage of class members who
    20
    suffered no injury is nearly one-third of the entire class, which is far greater than a
    marginal 5.7 percent in Bell, and cannot reasonably be described as only slightly
    overinclusive, as stated in Sevidal.
    Plaintiffs also contend that trial court's ascertainability analysis improperly
    ignored Bufil v. Dollar Financial Group, Inc. (2008) 
    162 Cal.App.4th 1193
    , 1208, which
    — like this case — concerned a proposed class action alleging that the employer violated
    the wage and hour laws by requiring employees to sign unlawful meal waiver forms. (Id.
    at p. 1198.) Plaintiffs argue that like in Bufil, the trial court should have concluded that
    although some class members may not have been impacted by the allegedly illegal meal
    waivers, the class is still ascertainable and not overbroad. We reject Plaintiffs' argument
    because the class definition in Bufil was specifically designed to eliminate the problem of
    overbreadth by including only those employees whose time records showed them to be
    impacted by the allegedly illegal policy. (Id. at p. 1201.) Accordingly, the proposed
    class in Bufil was "by definition . . . ascertainable from [the employer's] records" because
    it specifically included only those employees who timesheet records show that they were
    injured by the employer's alleged illegal policy. (Id. at p. 1208.) Here, in contrast,
    Plaintiffs have not even attempted to define a class that would only include those RN's
    who were impacted by Sharp's meal waiver policy, and they further have not shown that
    it would even be possible to narrow the class using existing records. Instead — as the
    trial court correctly pointed out — Plaintiffs have proposed a grossly overbroad class that
    sweeps in all of Sharp's nonexempt RN's regardless of the fact that approximately
    30 percent of them have not been impacted by Sharp's meal waiver policy.
    21
    E.     The Trial Court Was Within Its Discretion to Determine That Plaintiffs Failed to
    Establish That the Case Would Be Manageable as a Class Action with Respect to
    the Meal Waiver Theory
    We next examine Plaintiffs' contention that the trial court abused its discretion in
    determining that the litigation of the Meal Waiver Theory would not be manageable as a
    class action.
    As we have explained, in addition to establishing that common questions of law or
    fact predominate, to prevail on a class certification motion, a party must establish that "a
    class action would be superior to individual lawsuits," taking into account " '[t]he
    difficulties, if any, that are likely to be encountered in managing a class action.' "
    (Basurco, supra, 108 Cal.App.4th at p. 121.) In Plaintiffs' reconsidered motion, Plaintiffs
    supplied only vague explanations of how the Meal Waiver Theory would be manageable
    as a class action. Plaintiffs argued, "In the instant action, the Court may provisionally
    certify the class and one or more subclasses corresponding to each theory of recovery
    advanced by Plaintiffs, until it can be determined through examination of Sharp's records
    or random sampling or some combination thereof, whether sub-classes should be further
    sub-divided to account for differences between, say, RN[']s assigned to eight-hour and
    twelve-hours schedules. In addition to subclasses, California courts have endorsed
    several other methods to manage individual issues and preserve the efficiencies of class
    treatment, including pattern and practice evidence, statistical evidence, sampling
    evidence, expert testimony, and other indicators of a defendant's centralized practices."
    When discussing manageability, Plaintiffs referred specifically to the Meal Waiver
    Theory only in a brief sentence: "[T]he lawfulness of Sharp's systemwide late lunching,
    22
    meal waiver forms and EDUC payroll practices can be determined 'in the abstract,' i.e., as
    a matter of law with limited or no factual inquiry." Although Plaintiffs acknowledged
    that for each theory "calculating damages . . . may require some individualized inquiry,"
    they claimed — without providing specifics — that "these issues can nonetheless be
    resolved on the basis of Sharp's official records — above all, putative class members'
    time cards and payroll reports."
    On appeal, Plaintiffs continue to fall back on their vague assertions about the
    manageability of the Meal Waiver Theory as a class action, without any citation to the
    record. Plaintiffs state in their appellate brief that they "repeatedly have informed the
    trial court that they have examined some (albeit not all) of Sharp's records . . . and are
    currently satisfied they can provide their case (on each theory) using these records alone.
    Put simply, what else does the trial court want or need at the early stage of the
    litigation . . . ?" Plaintiffs argue that because Sharp is required by federal law to maintain
    time records for its employees, the appropriate documentation for the classwide
    resolution of this case must exist in Sharp's files. However, they fail to specifically
    explain exactly what type of documentation they would rely on to establish their case if it
    is litigated as a class action and how that documentation relates to the issues that would
    have to be resolved.
    Based on Plaintiffs' deficient showing on the issue of manageability, the trial court
    stated that the Meal Waiver Theory would be inappropriate for class treatment because
    Plaintiffs had not established that procedural tools were available to make it manageable
    on a class basis. As the trial court explained, "Instead of a specific plan, Plaintiffs merely
    23
    informed the Court of tools it may use to test the viability of their theories. This is not
    sufficient." (Italics omitted.) The trial court pointed out that issues particular to each
    class member could arise in litigating the Meal Waiver Theory, such as whether class
    members self-scheduled their meal periods, whether they already received a premium
    payment on a day they delayed their meal period, and whether they were one of the
    approximate 30 percent of class members who did not work long enough shifts to be
    impacted by the meal waivers. With reference to these issues, the trial court pointed out
    that it could not "assume, based only on Plaintiffs' counsel's assertion, that all can be
    known simply by referencing the time cards."9
    We agree with the trial court that Plaintiffs have not met their burden to establish
    how this case can be managed as a class action with respect to the Meal Waiver Theory
    or any of their theories. Plaintiffs have provided nothing but vague assertions that they
    intend to rely on Sharp's employment records. They have made no attempt to explain
    what those records are or how those records can and will be used in the litigation. To
    prevail on a class certification motion, "[i]t is not sufficient . . . simply to mention a
    9       As we understand the trial court's comments, it was not rejecting any specific
    methodology that Plaintiffs were proposing to manage the litigation as a class action, and
    thus its decision on manageability did not touch on the issue currently before our
    Supreme Court regarding whether certain representative testimony and statistical
    evidence may be used as trial management strategies in a wage and hour class action.
    (Duran v. U.S. Bank National Assn. (May 16, 2012, S200923), granting review of Duran
    v. U.S. Bank National Assn. (2012) 
    203 Cal.App.4th 212
    ; see also Wal–Mart Stores, Inc.
    v. Dukes (2011) 564 U.S. __ [
    131 S.Ct. 2541
    , 
    180 L.Ed.2d 374
    ].) Instead, the trial court
    ruled that Plaintiffs had not met their burden to establish manageability precisely because
    they had not identified any approach to making this case manageable as a class action.
    24
    procedural tool; the party seeking class certification must explain how the procedure will
    effectively manage the issues in question . . . ." (Dunbar v. Albertson's, Inc. (2006) 
    141 Cal.App.4th 1422
    , 1432-1433.) As our Supreme Court has explained in the context of
    discussing the requirements for certification of a nationwide class, a trial court "cannot
    simply rely on counsel's assurances of manageability" and "cannot accept 'on faith' " the
    accuracy of counsel's assertions as to manageability. (Washington Mutual, supra, 24
    Cal.4th at p. 924.) "[C]lass action proponents 'should not expect the court to ferret
    through, disseminate, and craft manageable schemes' " from the material provided by
    plaintiffs, because that "burden 'clearly rests' with the proponents." (Id. at pp. 924-
    925.)10
    By failing to provide any specifics as to how they proposed to litigate the Meal
    Waiver Theory as a class action despite the issues requiring individual proof, Plaintiffs
    failed to meet their burden. Because Plaintiff provided only vague assurances that the
    litigation would be manageable as a class action, the trial court was well within its
    discretion to conclude Plaintiffs failed to meet their burden on that issue with respect to
    the Meal Waiver Theory.
    10     Further, although Plaintiffs vaguely suggested that subclasses could be created to
    help manage this litigation, a court need not consider the creation of subclasses when
    "plaintiffs failed to provide the trial court with a concrete proposal describing how such
    subclasses would be defined, how they would be administered, or how they would help
    the court deal with the complexities inherent in the proposed class." (Block v. Major
    League Baseball (1998) 
    65 Cal.App.4th 538
    , 545.)
    25
    F.     Reversal Is Not Warranted on the Basis That the Trial Court Considered the
    Merits of the Meal Waiver Theory
    Relying on our Supreme Court's comment in Fireside, 
    supra,
     40 Cal.4th at
    page 1074, that "[t]rial courts in class action proceedings should decide whether a class is
    proper, and if so, order class notice before ruling on the substantive merits of an action,"
    Plaintiffs argue that the trial court abused its discretion by considering the merits of the
    Meal Waiver Theory.
    Our Supreme Court's view on whether the merits should be considered in ruling on
    a class action certification motion was recently clarified in Brinker Restaurant Corp. v.
    Superior Court (2012) 
    53 Cal.4th 1004
     (Brinker). Brinker stated that "any 'peek' a court
    takes into the merits at the certification stage must 'be limited to those aspects of the
    merits that affect the decisions essential' to class certification." (Id. at p. 1024.)
    However, in this case, we need not decide whether the trial court's discussion of the
    merits of the Meal Waiver Theory was permissible under the rule expressed in Brinker
    because the trial court provided three alternative bases for its ruling denying class
    certification on the Meal Waiver Theory.
    Specifically, as we have explained, apart from discussing the merits of the Meal
    Waiver Theory, the trial court decided that as to the Meal Waiver Theory (1) the class
    was overbroad and unascertainable; (2) individual issues would predominate; and
    (3) Plaintiffs had not established the manageability of litigating the Meal Waiver Theory
    as a class action. We concluded above that Plaintiffs' challenge to two of the alternative
    bases for the trial court's ruling on the Meal Waiver Theory lack merit: the class was
    26
    overbroad and the case was not manageable as a class action. Further, Plaintiffs present
    no argument challenging the remaining of the trial court's three alternative bases for
    denying class certification basis, namely, that individual issues predominate.
    In our review of the trial court's class certification ruling, " '[a]ny valid pertinent
    reason stated will be sufficient to uphold the order.' " (Linder, supra, 23 Cal.4th at p. 436;
    see also Kaldenbach v. Mutual of Omaha Life Ins. Co. (2009) 
    178 Cal.App.4th 830
    , 844
    [reversal not warranted "simply because some of the court's reasoning was faulty, so long
    as any of the stated reasons are sufficient to justify the order"].) Here, because the trial
    court gave three valid pertinent reasons other than its consideration of the merits, we
    reject Plaintiffs' argument that the trial court's order denying class certification should be
    reversed based on the court's consideration of the merits of the Meal Waiver Theory.11
    11     We note that Plaintiffs' reply brief raises several additional substantive issues that
    were not presented in the opening brief, all of which are premised on our Supreme
    Court's recent opinion in Brinker, supra, 
    53 Cal.4th 1004
    , issued after Plaintiffs filed
    their opening appellate brief. The basic argument in Plaintiffs' reply brief is that because
    of Brinker, "all of Plaintiffs' theories should be placed back before the trial court," even
    those that were not raised in the opening brief as a basis for the appeal, and even those
    that were not the subject of Plaintiffs' reconsidered motion. We have incorporated
    Brinker into our analysis to the extent it is relevant to the issues raised in Plaintiffs'
    opening brief, but we do not address any new substantive grounds for appeal that
    Plaintiffs raised for the first time in their reply brief. (See Reichart v. Hoffman (1997) 
    52 Cal.App.4th 754
    , 764; People v. Zamudio (2008) 
    43 Cal.4th 327
    , 353 ["Normally, a
    contention may not be raised for the first time in a reply brief."].)
    Further, we note that Plaintiffs' opening brief contains several vague and
    undeveloped arguments that are either not set forth in the argument section of their brief
    or are not contained within the scope of their argument headings. We do not address
    those arguments as they are not properly presented. (Alameida v. State Personnel Bd.
    (2004) 
    120 Cal.App.4th 46
    , 59 ["We may disregard arguments not properly presented
    under appropriate headings."].)
