OPINION AND ORDER

JOHN G. KOELTL, District Judge:

The plaintiffs bring this action under the Fair Labor Standards Act ("FLSA"), 29 U.S.C. § 201 et seq., and the New York Labor Law ("NYLL"), §§ 190 et seq. & 650 et seq., claiming various violations of their right to receive a minimum wage and overtime compensation. The plaintiffs are current and former hourly employees of RiverBay Corp. ("RiverBay"). On December 20, 2013, the Court granted the plaintiffs' motion for conditional certification of a collective action pursuant to Section 216(b) of the FLSA. The plaintiffs now move for certification of three proposed NYLL Subclasses pursuant to Rule 23 of the Federal Rules of Civil Procedure. For the reasons that follow, the plaintiffs' motion is granted.

I.

The factual background and procedural history of this case are set forth in the Court's Opinion and Order addressing the defendants' motion to dismiss and the parties' cross-motions for summary judgment, which is being issued together with this Opinion. Familiarity with that Opinion is assumed. The following facts relevant to the present motion are undisputed unless otherwise noted.

A.

Named Plaintiffs Katherine Bell, Jonathan Frias, Rosaly Ramirez, Lorna Thomas, and Linda Williams are current and former hourly employees of RiverBay. (Am. Compl. ¶¶ 8-12.) Defendant River-Bay manages Co-Op City, which is the largest cooperative housing development in the world. (Am. Compl. ¶ 14.) Defendant Marion Scott is the exclusive property manager for all of RiverBay's residential and commercial properties. (Am. Compl. ¶ 15.) Individual Defendants Vernon Cooper and Peter Merola are River-Bay's General Manager and Director of Finance, respectively. (Am. Compl. ¶¶ 17-18.)

In this action, the plaintiffs claim various violations of their rights to minimum wage and overtime compensation under the FLSA and the NYLL. These claims fall into three categories: the plaintiffs allege that the defendants unlawfully provided compensatory time off in lieu of cash for overtime hours worked by the plaintiffs (the "comp time claims"); that the defendants unlawfully failed to incorporate a nighttime wage differential in the plaintiffs' base pay when calculating the plaintiffs' overtime wages (the "nighttime differential claims"); and that the defendants impermissibly reduced the plaintiffs' compensation by under-counting the hours that the plaintiffs worked in various ways (the "under-counting claims").

B.

In moving for class certification, the named plaintiffs seek to represent three proposed Subclasses of current and former hourly employees at RiverBay who have claims for the unlawful deprivation of wages in violation of the NYLL.

Proposed Subclass 1 includes hourly employees at RiverBay who allege that they clocked in and began working before the start of their scheduled shifts, or continued to work after the end of their scheduled shifts and then clocked out late, and were not compensated for work performed during these on-the-clock off-schedule "gap" periods.1 These plaintiffs allege that RiverBay had a corporate policy of paying hourly employees according to their scheduled shifts even though the employees' payroll records indicated that they clocked in early or clocked out late, and that the deprivation of wages for hours earned during on-the-clock "gap" periods was unlawful under the NYLL.

Proposed Subclass 2 includes hourly employees at RiverBay who allege that they were provided overtime compensation in the form of compensatory time off ("comp time") in lieu of cash for time worked in excess of forty hours per week. These plaintiffs allege that RiverBay had a corporate policy of permitting hourly employees to receive overtime compensation in the form of comp time, and that this policy is unlawful under the NYLL.

Finally, Proposed Subclass 3 includes hourly employees at RiverBay who earned premium compensation for work performed during night shifts ("nighttime differential" pay), and who allege that RiverBay had a policy of excluding this nighttime differential pay from their regular wages when calculating their overtime compensation, in violation of the NYLL.

C.

On December 20, 2013, the Court granted the plaintiffs' motion for conditional certification of a collective action and Court-authorized notice pursuant to Section 216 of the FLSA, 29 U.S.C. § 216. (See Dec. 20, 2013 Hr'g Tr. at 59.) The Court approved the final language for the notice in a Memorandum Opinion and Order dated January 30, 2014, and on February 20, 2014, the notice was sent to a list of approximately 1,700 potential plaintiffs that had been furnished by the defendants. At the time the present motion was filed, ninety-six opt-in plaintiffs had consented to joining the conditionally certified collective action. (Decl. of Wade C. Wilkinson in Supp. of Pls.' Mot. for Certification of the N.Y. Subclasses ("Wilkinson Decl.") ¶ 6.)

On January 27, 2014, the defendants moved to dismiss the plaintiffs' federal and state comp time and nighttime differential claims on the ground that they are preempted under § 301 of the Labor-Management Relations Act ("LMRA"), 29 U.S.C. § 185(a), and to dismiss Defendant Merola from the action on the ground that he is not individually liable under the FLSA or the NYLL. On February 6, 2014, Plaintiffs Frias, Thomas, and Williams moved for summary judgment on their comp time claims, and Plaintiffs Bell, Frias, Ramirez, Thomas, and Williams moved for summary judgment on their nighttime differential claims. On March 10, 2014, the defendants cross-moved for summary judgment on these same claims. In the accompanying Opinion, the Court denied the motion to dismiss, granted the summary judgment motions brought by Frias and Thomas for liability on their comp time claims, and denied all other summary judgment motions. The plaintiffs filed the present motion for certification of three NYLL Subclasses on March 17, 2014.

II.

Before certifying a class, the Court must determine that the party seeking certification has satisfied the four prerequisites of Rule 23(a): (1) numerosity, (2) commonality, (3) typicality, and (4) adequacy of representation. See Fed.R.Civ.P. 23(a); Teamsters Local 445 Freight Div. Pension Fund v. Bombardier, Inc., 546 F.3d 196, 202-03 (2d Cir.2008); In re Initial Pub. Offerings Sec. Litig. ("In re IPO"), 471 F.3d 24, 32 (2d Cir.2006). The Court must find, more specifically, that: "(1) 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 the representative parties will fairly and adequately protect the interests of the class." Fed.R.Civ.P. 23(a). The Court must also find that the class qualifies under one of the three sets of criteria set forth in Rule 23(b). See Amchem Prods., Inc. v. Windsor, 521 U.S. 591, 614, 117 S.Ct. 2231, 138 L.Ed.2d 689 (1997); Teamsters, 546 F.3d at 203; In re IPO, 471 F.3d at 32.

The plaintiffs here seek certification under Rule 23(b)(3), which provides for a class to be maintained where "the questions of law or fact common to the class members predominate over any questions affecting only individual members, and ... a class action is superior to other available methods for fairly and efficiently adjudicating the controversy." Fed. R.Civ.P. 23(b)(3); see also Comcast Corp. v. Behrend, ___ U.S. ___, 133 S.Ct. 1426, 1431, 185 L.Ed.2d 515 (2013). If the requirements of 23(a) have been met, and the claims fall within the scope of Rule 23(b)(3), a court may, in its discretion, certify the class. See In re IPO, 471 F.3d at 41 ("[A] district judge may certify a class only after making determinations that each of the Rule 23 requirements has been met.").

"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 in fact sufficiently numerous parties, common questions of law or fact, etc." Wal-Mart Stores, Inc. v. Dukes, ___ U.S. ___, 131 S.Ct. 2541, 2551, 180 L.Ed.2d 374 (2011). Plaintiffs seeking class certification bear the burden of demonstrating by a preponderance of the evidence that the proposed class meets each of the requirements for class certification set forth in Rule 23. Teamsters, 546 F.3d at 202. When assessing whether plaintiffs have met this burden, courts must take into account "all of the relevant evidence admitted at the class certification stage." In re IPO, 471 F.3d at 42. A court may certify a class only after determining that "whatever underlying facts are relevant to a particular Rule 23 requirement have been established." Id. at 41. "[T]he obligation to make such determinations is not lessened by overlap between a Rule 23 requirement and a merits issue," although a court "should not assess any aspect of the merits unrelated to a Rule 23 requirement." Id.; see also Mazzei v. Money Store, 288 F.R.D. 45, 54-55 (S.D.N.Y.2012).

In ruling on a motion for class certification, "[c]ourts have discretion to create additional classes or split a class into subclasses...." Mazzei, 288 F.R.D. at 56 (citations omitted). When exercising its discretion to certify subclasses, a court must assure itself that each subclass independently meets the requirements of Rule 23. Id.; Burka v. N.Y. City Transit Auth., 110 F.R.D. 595, 601 (S.D.N.Y.1986).

Where, as here, a collective action under the FLSA involves claims under the NYLL, "courts in the Second Circuit routinely certify class actions ... so that New York State and federal wage and hour claims are considered together." Damassia v. Duane Reade, Inc., 250 F.R.D. 152, 163 (S.D.N.Y.2008) (collecting cases); see also Lee v. ABC Carpet & Home, 236 F.R.D. 193, 202-03 (S.D.N.Y.2006) ("[W]here a collective action under the FLSA that is based on the same set of facts has been approved, there is an inclination to grant class certification of state labor law claims." (citing Ansoumana v. Gristede's Operating Corp., 201 F.R.D. 81, 86 (S.D.N.Y.2001))).

III.

The plaintiffs' first proposed Subclass is defined to include current and former RiverBay employees who have been denied compensation for work performed after clocking in but before the start of a scheduled shift, or after the end of a scheduled shift but before clocking out. The defendants argue that certification of this Subclass should be denied because this Subclass does not meet the commonality or typicality requirements of Rule 23(a)(2) and (3), and because the plaintiffs cannot demonstrate that common questions of law or fact predominate over individualized inquiries that would be required to establish liability and damages for the plaintiffs' schedule-based pay claims, such that the predominance requirement of Rule 23(b)(3) is not satisfied.

A.

The numerosity requirement of Rule 23(a)(1) is presumed satisfied for classes with more than forty members. See Consol. Rail Corp. v. Town of Hyde Park, 47 F.3d 473, 483 (2d Cir.1995). Here, the total number of plaintiffs in all three subclasses is approximately 1,700. The plaintiffs assert that Subclass 1 consists of more than forty members, (see Wilkinson Decl. ¶ 6), and the defendants do not oppose certification of Subclass 1 on the ground that the numerosity requirement is not satisfied. Accordingly, the Court concludes that Subclass 1 is sufficiently large to satisfy the numerosity requirement of Rule 23(a)(1). See Katz v. Image Innovations Holdings, Inc., No. 06cv3707, 2010 WL 2926196, at *3 (S.D.N.Y. July 22, 2010).

B.

Rule 23(a)(2) requires a showing that "there are questions of law or fact common to the class." Fed.R.Civ.P. 23(a)(2). To satisfy the commonality requirement, class members' claims must "depend upon a common contention," and the common contention "must be of such a nature that it is capable of classwide resolution." Dukes, 131 S.Ct. at 2551. The plaintiffs contend that RiverBay has a corporate policy of paying all hourly employees according to their scheduled shifts, rather than their on-the-clock hours, and that this policy routinely deprives the plaintiffs of compensation for work performed after clocking in but before the start of a shift, or work performed after the end of a shift but before clocking out. The plaintiffs argue that a determination of the existence of this policy will facilitate the classwide resolution of the schedule-based pay claims under the NYLL.

"To establish liability under the... NYLL on a claim for unpaid overtime, a plaintiff must prove that he performed work for which he was not properly compensated, and that the employer had actual or constructive knowledge of that work." Eschmann v. White Plains Crane Serv., Inc., No. 11cv 5881, 2014 WL 1224247, at *4 (E.D.N.Y. Mar. 24, 2014) (citation and internal quotation marks omitted). In general, the NYLL incorporates the overtime requirements of the FLSA. N.Y. Comp.Codes R. & Regs. tit. 12, § 142-2.2. The FLSA requires that for a workweek longer than forty hours, an employee who works in excess of forty hours must be compensated time and a half for the excess hours. See 29 U.S.C. § 207(a)(1).

The record on this class certification motion strongly supports the existence of a policy at RiverBay of paying employees only for their scheduled shifts when payroll records indicate that the employees worked longer than their scheduled shifts. (See, e.g., Wilkinson Decl., Ex. D at 27-28, Ex. E at 116-17.) This alleged policy is the cause of the injuries alleged in Subclass 1, and its establishment on the merits is therefore "at the `core' of the cause of action alleged" by the Subclass members. Espinoza v. 953 Assocs. LLC, 280 F.R.D. 113, 127 (S.D.N.Y.2011). Moreover, it is undisputed that payroll records would enable a comparison between hours spent on the clock and hours that were actually compensated.2 Thus, for a given plaintiff, determining when application of the alleged schedule-based pay policy resulted in overtime liability for time worked in excess of forty hours in a given workweek would be largely a matter of arithmetic, with inputs from the payroll records. For these reasons, the establishment of the alleged RiverBay-wide schedule-based pay policy would carry the litigation of the claims at issue in Subclass 1 a significant step toward its resolution. See Dukes, 131 S.Ct. at 2551 (noting that for commonality purposes, a "common question" must be able "to generate common answers apt to drive the resolution of the litigation"). The common contention of a classwide policy of denying compensation for pre- and post-shift on-the-clock work is therefore sufficient to satisfy the commonality requirement of Rule 23(a)(2) for Subclass 1. Cf. Morangelli v. Chemed Corp., 922 F.Supp.2d 278, 307-08 (E.D.N.Y.2013); Morris v. Affinity Health Plan, Inc., 859 F.Supp.2d 611, 615-16 (S.D.N.Y.2012); Espinoza, 280 F.R.D. at 127.

While the defendants invoke Wal-Mart Stores, Inc. v. Dukes in opposing certification of Subclass 1, nothing about that case precludes a finding that the commonality requirement has been satisfied here. The Supreme Court in Dukes concluded that the commonality requirement had not been satisfied in a class action brought by employees alleging employment discrimination under Title VII. The Court found that the plaintiffs' claims did not rest upon a common contention capable of classwide resolution because the plaintiffs could not claim that a uniform employment policy was the cause of their injuries. See 131 S.Ct. at 2554. The plaintiffs had alleged that their employer had a corporate policy of allowing discretion by local supervisors over employment decisions, and that supervisors had exercised this discretion in a discriminatory manner. Id. at 2548. The Court concluded that this was "just the opposite of a uniform employment practice that would provide the commonality needed for a class action; it [wa]s a policy against having uniform employment practices." Id. at 2554. Thus, deciding the plaintiffs' claims would require analyzing the employment decisions of individual managers in individual cases, and there was therefore no classwide answer as to why each plaintiff was a victim of discrimination. Id.

Here, by contrast, the evidence points clearly to the existence of a corporate employment policy with an impact on employees across RiverBay. RiverBay's payroll coordinator testified that RiverBay employees are "paid to schedule." (Wilkinson Decl., Ex. D at 27.) The employee depositions submitted in connection with this motion indicate unanimously that the plaintiffs performed on-the-clock pre- and post-schedule work and were not paid for it, and many employees testified that they knew others who also performed uncompensated on-the-clock work. (See, e.g., Decl. of Wade C. Wilkinson in Further Supp. of and in Reply to Defs.' Opp. to Pls.' Mot. for Certification of the N.Y. Subclasses ("Wilkinson Reply Decl."), Ex. N at 18, 21-22, 51, Ex. O at 60, Ex. P at 19-20; Wilkinson Decl., Ex. G at 92-93, Ex. H at 45-46, 83, 111-13, Ex. I at 38, 71, 73, 92, 102, Ex. J at 54-56, 64, 164-66, 225, 250, 256, Ex. K at 65-66, 69, 86, 89, Ex. Q at 75-77.) The extent to which this uncompensated on-the-clock work was performed during weeks in which plaintiffs worked more than forty hours may require individualized determinations,3 but these determinations are likely to consist of mechanical calculations based on payroll records and undisputed employment policies at RiverBay. See, e.g., Schear v. Food Scope Am., Inc., 297 F.R.D. 114, 126 (S.D.N.Y.2014); In re U.S. Foodserv. Inc. Pricing Litig., No. 06cv1657, 2011 WL 6013551, at *16 (D.Conn. Nov. 29, 2011), aff'd, 729 F.3d 108 (2d Cir.2013). Moreover, it is axiomatic that "[t]he commonality requirement may be met when individual circumstances of class members differ," as long as class members' "injuries derive from a unitary course of conduct." Espinoza, 280 F.R.D. at 127 (citation omitted); see also Morangelli, 922 F.Supp.2d at 308; Whitehorn v. Wolfgang's Steakhouse, Inc., 275 F.R.D. 193, 199 (S.D.N.Y.2011). Thus, courts addressing the commonality requirement after Dukes have typically held that the requirement is satisfied where employees claim that they were denied minimum wage or overtime compensation as a result of a corporate employment policy. See Shahriar v. Smith & Wollensky Rest. Grp., Inc., 659 F.3d 234, 252 (2d Cir.2011); Espinoza, 280 F.R.D. at 127; Youngblood v. Family Dollar Stores, Inc., No. 09cv3176, 2011 WL 4597555, at *4 (S.D.N.Y. Oct. 4, 2011); Ramos v. SimplexGrinnell LP, 796 F.Supp.2d 346, 355 (E.D.N.Y.2011) (opinion of the Magistrate Judge). The evidence in this case supports the existence of a RiverBay-wide payroll policy that was the reason for the Subclass members' alleged injuries under the NYLL, and the commonality requirement is therefore satisfied for Subclass 1.

C.

Rule 23(a)(3) is satisfied when "the claims of the class representatives [are] typical of those of the class, and ... when each class member's claim arises from the same course of events, and each class member makes similar legal arguments to prove the defendant's liability." Marisol A. v. Giuliani, 126 F.3d 372, 376 (2d Cir.1997). "While it is settled that the mere existence of individualized factual questions with respect to the class representative's claim will not bar class certification, class certification is inappropriate where a putative class representative is subject to unique defenses which threaten to become the focus of the litigation." Gary Plastic Packaging Corp. v. Merrill Lynch, Pierce, Fenner & Smith, Inc., 903 F.2d 176, 180 (2d Cir.1990) (citations omitted). The Supreme Court has emphasized that "the commonality and typicality requirements of Rule 23(a) tend to merge. Both serve as guideposts for determining whether under the particular circumstances maintenance of a class action is economical and whether the named plaintiff's claim and the class claims are so interrelated that the interests of the class members will be fairly and adequately protected in their absence." Dukes, 131 S.Ct. at 2551 n. 5 (citation omitted).

The defendants have not proffered any arguments that address specifically whether the typicality requirement is satisfied for Subclass 1. To the extent that the defendants emphasize the individualized inquiries that may be necessary to establish liability and damages, any such inquiries do not defeat a finding that the named plaintiffs' claims are typical of those of the proposed Subclass. See Espinoza, 280 F.R.D. at 128 ("[T]he minimum wage and overtime claims alleged by Plaintiffs are similar to those of the class members and arise from the same allegedly unlawful practices and policies .... Typicality is satisfied despite differences in damages arising from a disparity in injuries among the class members."). Here, the named plaintiffs have testified that they were harmed by the conduct alleged to have injured the class, (see, e.g., Wilkinson Decl., Ex. I at 38, Ex. J at 250, Ex. K at 86), and the defendants have not indicated any specific factual defenses applicable to the named plaintiffs' claims that would be atypical of the class. Accordingly, the typicality requirement is satisfied for Subclass 1.

D.

Adequacy under Rule 23(a)(4) consists of two requirements: "First, class counsel must be qualified, experienced and generally able to conduct the litigation. Second, the class members must not have interests that are antagonistic to one another." In re Drexel Burnham Lambert Grp., Inc., 960 F.2d 285, 291 (2d Cir.1992) (citation omitted); see also Dukes, 131 S.Ct. at 2551 n. 5 ("[T]he [adequacy] requirement... raises concerns about the competency of class counsel and conflicts of interest."). The defendants do not challenge the adequacy of representation in this action, and there are no evident conflicts of interests in the Subclass. Plaintiffs' counsel has pursued a number of similar actions and has vigorously litigated the action before this Court. Accordingly, the adequacy requirement is satisfied for Subclass 1. See Damassia, 250 F.R.D. at 158; In re Buspirone Patent Litig., 210 F.R.D. 43, 58 (S.D.N.Y.2002).

E.

"Although it is not explicitly spelled out in Rule 23, courts have added an implied requirement of ascertainability with respect to the class definition." Schear, 297 F.R.D. at 125 (citation and internal quotation marks omitted). Under this requirement, a class must be identifiable before it may be properly certified. Id. "An identifiable class exists if its members can be ascertained by reference to objective criteria." Id. (citation omitted). Here, neither party has addressed the ascertainability requirement. It is nevertheless clear that the members of Subclass 1 can be ascertained by reference to objective criteria, such as dates of employment and information from payroll records. See, e.g., Morris v. Alle Processing Corp., No. 08cv4874, 2013 WL 1880919, *6-7 (E.D.N.Y. May 6, 2013). Accordingly, the implied ascertainability requirement is satisfied for Subclass 1.

F.

In addition to satisfying the Rule 23(a) prerequisites, the plaintiffs must show, pursuant to Rule 23(b)(3), "that the questions of law or fact common to class members predominate over any questions affecting only individual members, and that a class action is superior to other available methods for fairly and efficiently adjudicating the controversy." Fed.R.Civ.P. 23(b)(3).

1.

The plaintiffs here argue that the predominance requirement is satisfied for Subclass 1 because the Subclass members have suffered the same injury under the NYLL resulting from the same general policy, and any individualized determinations in the action will consist mainly of mechanical calculations that can be performed on the basis of payroll records, and will therefore not overwhelm the litigation. The defendants argue that Subclass 1 does not satisfy the predominance requirement because individualized issues will predominate over classwide issues in the determination of liability and damages. This is so, they argue, because it cannot be assumed that the time an employee spends "clocked in" is an accurate reflection of time spent "working" for purposes of overtime liability under the NYLL; thus, in order to establish liability and damages, the Court will have to conduct individualized, fact-specific inquiries into whether a given plaintiff was actually working during the time that plaintiff was on the clock.

For their position, the defendants rely primarily on Babineau v. Federal Express Corp., 576 F.3d 1183 (11th Cir.2009). Babineau involved claims by employees of Federal Express Corporation, Inc. ("FedEx") for breach of contract and unjust enrichment resulting from FedEx's alleged failure to pay its employees for "gap" periods — that is, periods between clocking in and the start of a scheduled shift, or between the end of a scheduled shift and clocking out. 576 F.3d at 1185, 1187-88. The district court had concluded that Rule 23(b)(3) was not satisfied because the record indicated a significant likelihood that plaintiffs were not actually performing work-related duties during "gap" periods — thus, a determination of liability would depend upon individualized inquiries that were likely to predominate over common questions. See id. at 1192-93. Although the claims at issue in Babineau were for breach of contract, the plaintiffs had argued that the employment contracts at issue incorporated state and federal law, including federal regulations defining "hours worked" as "all periods in which the employee is suffered or permitted to work whether or not required to do so," and "time given by the employee to the employer even though part of the time may be spent in idleness." See id. at 1192 (quoting 29 C.F.R. §§ 4.178 & 778.223).

The Court of Appeals for the Eleventh Circuit concluded that even assuming the federal regulations promulgated under the FLSA were applicable, there was a realistic likelihood based on the record that individualized inquiries into whether a plaintiff was working during "gap" periods would predominate over classwide issues. See id. at 1193-94. In reaching this conclusion, the Court of Appeals emphasized another federal regulation that states: "In those cases where time clocks are used, employees who voluntarily come in before their regular starting time or remain after their closing time, do not have to be paid for such periods provided, of course, that they do not engage in any work." Id. at 1193 (quoting 29 C.F.R. § 785.48(a)). In light of this definition of "work," and "particularly in light of employee testimony regarding the various non-work-related activities that took place during the gap periods and the various personal reasons that employees listed for coming in early and staying late," the district court had not abused its discretion in denying class certification on Rule 23(b)(3) grounds. Id. at 1192-93.

The defendants argue that here, as in Babineau, individualized inquiries into whether a given plaintiff was working during on-the-clock pre- and post-shift "gaps" will predominate over classwide issues. However, the conclusions reached in Babineau are not persuasive in this case. The court in Babineau affirmed the denial of class certification because "[e]ven if FedEx policies pressured some employees to arrive early or stay late, it [wa]s clear from the record that other employees did so voluntarily and for purely personal reasons," and therefore not all on-the-clock time indicated in the payroll records would have been compensable under the employment contracts. Id. at 1193.

In this case, by contrast, the record supports the conclusion that the plaintiffs were working during pre- and post-shift on-the-clock "gaps."4 All nine plaintiffs whose deposition transcripts were submitted in connection with this motion testified that they perform work-related duties when they clock in early or clock out late.5 (See, e.g., Wilkinson Decl., Ex. G at 19-20, 23, 27, Ex. H at 45-46, Ex. I at 48, 70, 77, Ex. J at 54, 165, Ex. K at 66, 82, 90, Ex. Q at 186; Wilkinson Reply Decl., Ex. N at 22, 119, Ex. O at 62, Ex. P at 54.) Many plaintiffs testified that their employers had actual knowledge of this work, (see, e.g., Wilkinson Decl., Ex. G at 27, Ex. H at 62, Ex. K at 68-69, 111), and for other employees, constructive knowledge may suffice.6 See Kuebel v. Black & Decker, Inc., 643 F.3d 352, 361 (2d Cir.2011) ("To establish liability under the FLSA on a claim for unpaid overtime, a plaintiff must prove that he performed work for which he was not properly compensated, and that the employer had actual or constructive knowledge of that work."); N.Y. Comp.Codes R. & Regs. tit. 12, § 142-2.2 (adopting the overtime standards applicable under the FLSA into the NYLL overtime compensation requirements). In addition to these testifying plaintiffs, four other opt-in plaintiffs submitted sworn declarations in which they attest that they worked during pre- and post-shift "gap" periods, (see Wilkinson Reply Decl., Ex. Q ¶¶ 5-6, Ex. R ¶¶ 5-7, Ex. S ¶¶ 5-7, Ex. T ¶¶ 5-7), and twenty-two additional opt-in plaintiffs submitted responses to interrogatories in which they attest that they worked during pre- and post-shift "gap" periods.7 (See Wilkinson Reply Decl., Ex. U.)

Although individualized factual inquiries cannot be avoided, the Court has a duty to assess all of the relevant evidence admitted at the class certification stage and to resolve factual disputes relevant to each of the Rule 23 requirements, In re IPO, 471 F.3d at 41-42, and unlike in Babineau, the record here does not indicate a significant likelihood that individualized factual inquiries into whether individual plaintiffs were working during pre- and post-shift "gaps" will overwhelm the classwide resolution of the claims in Subclass 1.8 Cf. Indergit v. Rite Aid Corp., 293 F.R.D. 632, 654-58 (S.D.N.Y.2013) (finding the predominance requirement satisfied for a class involving claims that employees were misclassified as "exempt" under the NYLL, where, despite differences in the work duties of the plaintiffs, there were consistent patterns in the evidence, and the proposed class members were uniformly treated as "exempt"); Whitehorn, 275 F.R.D. at 200 ("[P]redominance is not defeated by the fact that potential plaintiffs worked at different restaurant locations and in different categories of tipped positions where, as here, Defendants admit that the pay policy was identical.").

To the contrary, the record suggests that if the plaintiffs succeed in demonstrating a corporate policy of routinely denying RiverBay employees compensation for pre- and post-shift work, the primary hurdle to recovery is likely to consist predominantly of arithmetical calculations based on payroll records and other documentary evidence.9 The plaintiffs have therefore established by a preponderance of the evidence that classwide issues will predominate over individualized inquiries, and, accordingly, the predominance requirement is satisfied for Subclass 1. See, e.g., Shahriar, 659 F.3d at 253 ("If Plaintiffs succeed in showing that the expediters, silver polishers, coffee makers, and/or managers were not eligible to receive tips under New York law, then each of the class plaintiffs will likely prevail on his or her ... claims, although class plaintiffs' individualized damages will vary."); Niemiec v. Ann Bendick Realty, No. 04cv897, 2007 WL 5157027, at *12 (E.D.N.Y. Apr. 23, 2008) ("The issues raised by [the overtime] claims are subject to generalized proof, and predominate over individual issues such as the alleged exempt status of the ... class members or the swapping of weekend schedules by class members...."); Noble v. 93 Univ. Place Corp., 224 F.R.D. 330, 345 (S.D.N.Y.2004) (finding the predominance requirement satisfied even though "determinations as to damages, exempt status, and alleged labor agreements w[ould] require individualized findings").

The defendants' conclusory invocation of the Supreme Court's recent decision in Comcast Corp. v. Behrend does not alter this result. In Comcast, the Court warned that Rule 23(b)(3) is not satisfied when the plaintiffs' theory of damages is not directly linked to the plaintiffs' theory of liability, because in such cases, "individual damage calculations will inevitably overwhelm questions common to the class." See 133 S.Ct. at 1433-35. The relevance of the holding in Comcast outside the antitrust context is not yet clear,10 but where, as here, damages can likely be proved by means of mechanical calculations of wages lost, Comcast poses no bar to a finding that predominance is satisfied. See, e.g., Leyva v. Medline Indus., Inc., 716 F.3d 510, 513-14 (9th Cir.2013); Schear, 297 F.R.D. at 126. Here, the plaintiffs' theory of damages is consistent with their theory of liability, and computing damages is likely to be a mere matter of arithmetic. Thus, the concerns articulated in Comcast are inapposite, and the predominance requirement of Rule 23(b)(3) is satisfied for Subclass 1.

2.

In order to satisfy Rule 23(b)(3), the plaintiffs must also show "that a class action is superior to other available methods for fairly and efficiently adjudicating the controversy." Fed.R.Civ.P. 23(b)(3). Here, the defendants do not object to class certification on superiority grounds, and it is clear that a class action is the superior method for the fair and efficient adjudication of the claims in Subclass 1. The plaintiffs are significant in number, and they are aware of no individual actions with similar claims against the defendants here. See Katz, 2010 WL 2926196, at *6. Moreover, the plaintiffs plausibly represent that given the relatively small amounts involved in the individual claims here, the likelihood is low that the plaintiffs would pursue separate actions if certification were denied. See Iglesias-Mendoza v. La Belle Farm, Inc., 239 F.R.D. 363, 373 (S.D.N.Y.2007). Accordingly, the superiority requirement is satisfied for Subclass 1. See Damassia, 250 F.R.D. at 164.

G.

For the foregoing reasons, the requirements of Rule 23(a) and (b)(3) are satisfied for Subclass 1, and the plaintiffs' motion to certify this Subclass is therefore granted.

IV.

The plaintiffs have moved for certification of two additional proposed Subclasses. Subclass 2 is defined to include current and former RiverBay employees who received comp time in lieu of cash for overtime hours, and Subclass 3 is defined to include current and former RiverBay employees who received premium "nighttime differential" pay for work performed during night shifts, and who allege that their overtime compensation was not upwardly adjusted to reflect the addition of this premium pay to their base compensation. The defendants raise only two limited objections to the certification of these two Subclasses. First, they argue that proposed Subclass 2 should not be certified because individualized issues with respect to liability and damages will predominate over classwide issues. Second, they argue that proposed Subclass 3 does not satisfy the adequacy requirement because the named plaintiffs do not have valid nighttime differential claims, and because the named plaintiffs have brought other claims in addition to their nighttime differential claims.

A.

The plaintiffs represent that Subclasses 2 and 3 will consist of more than forty members each, (see Wilkinson Decl. ¶ 6), and the defendants do not dispute this assertion. Thus, for the reasons that apply to Subclass 1, Subclasses 2 and 3 satisfy the numerosity requirement. See Consol. Rail Corp., 47 F.3d at 483 (holding that numerosity is presumed satisfied when a class consists of more than forty members); Katz, 2010 WL 2926196, at *3 (concluding that numerosity was satisfied on the basis of undisputed representations that the class was sufficiently large).

B.

With respect to Subclass 2, the plaintiffs contend that RiverBay had a corporate policy of providing comp time in lieu of cash for overtime hours, and that this raises a classwide issue that satisfies the commonality requirement of Rule 23(a)(2). The payment of comp time in lieu of cash wages for hours worked in excess of forty in a given workweek is unlawful under the NYLL.11 See N.Y. State Dep't of Labor, Opinion Letter No. RO-09-0161, at 2 (June 18, 2010). The record strongly supports the conclusion that RiverBay had a policy of paying comp time in lieu of cash wages for overtime, and that this policy applied across all departments at RiverBay. (See, e.g., Wilkinson Decl., Ex. C at 39, Ex. D at 96, Ex. M at 9, Ex. O at 1, Ex. P at 40.) Factual differences may exist as to how this policy was implemented across departments and CBAs, but it is nevertheless evident at this juncture that the payment of comp time was controlled on a RiverBay-wide basis, (see Wilkinson Decl., Ex. O at 1), and that the relevance of any factual differences in the way the comp time policy was implemented can be resolved by means of mechanical calculations based on payroll records and the payroll policies memorialized in the applicable CBAs. See Schear, 297 F.R.D. at 126; Espinoza, 280 F.R.D. at 127 ("The commonality requirement may be met when individual circumstances of class members differ...."). Differing factual circumstances do not preclude a finding of commonality where, as here, the alleged injuries of the class members derive from a unitary course of conduct alleged to have caused the plaintiffs' injuries. See Espinoza, 280 F.R.D. at 127. Accordingly, the commonality requirement is satisfied for Subclass 2.

For similar reasons, the commonality requirement is satisfied for Subclass 3. The defendants do not dispute that the failure to include premium pay, such as nighttime differential pay, in an hourly employee's regular rate of pay for purposes of calculating overtime liability would violate the NYLL to the extent that this occurred for weeks in which an employee worked more than forty hours.12 The record provides reasonable support for the conclusion that RiverBay had a corporate policy of calculating overtime pay without including nighttime differential pay, and that this policy affected a broad range of hourly employees across departments. (See, e.g., Wilkinson Decl., Ex. C at 90-93, Ex. Q at 26; Wilkinson Reply Decl., Ex. P at 38.) There is a reasonable likelihood that this policy was applied in weeks during which employees worked more than forty hours, and the plaintiffs plausibly assert that once this policy is established, determining weeks in which liability accrued would be largely a matter of arithmetic. (See, e.g., Wilkinson Decl., Ex. C at 97.) The defendants argue that individual differences exist among plaintiffs with respect to liability and damages because overtime policies differed by department and CBA, but such differences do not defeat a finding of commonality. See Espinoza, 280 F.R.D. at 127. Accordingly, the commonality requirement is satisfied for Subclass 3.

C.

There is no indication in the record that the claims of the named plaintiffs in Subclass 2 or 3 would hinge on issues or defenses that would "threaten to become the focus of the litigation," Gary Plastic Packaging Corp., 903 F.2d at 180 (citation omitted), and there is no express objection from the defendants to certification of Subclasses 2 or 3 on typicality grounds. The defendants argue that the named plaintiffs in Subclass 3 have failed to establish that they have valid nighttime differential claims, and this argument could plausibly be viewed as a challenge to typicality under Rule 23(a)(3). See Mazzei, 288 F.R.D. at 57-58 ("Under both the typicality and adequacy prongs of Rule 23(a), a purported class representative must have suffered the same injury as those people he or she seeks to represent." (citation omitted)). Nevertheless, the argument is without merit. Multiple named plaintiffs testified that their overtime compensation did not reflect nighttime differential pay that they had earned, (see, e.g., Wilkinson Decl., Ex. H at 94-96, Ex. J at 261-62), and there is no basis to assume that issues unique to these plaintiffs' claims would overwhelm the litigation. For these reasons, the typicality requirement is satisfied for Subclasses 2 and 3.

D.

As explained above, the record indicates that the first requirement under Rule 23(a)(4), adequacy of class counsel, is satisfied in this case. The second requirement — that class members "not have interests that are antagonistic to one another," In re Drexel Burnham Lambert Grp., 960 F.2d at 291-is also satisfied for Subclasses 2 and 3. The record indicates no evident conflicts of interest or any other reason to believe the named plaintiffs would not adequately represent the interests of the Subclasses. The defendants argue that the named plaintiffs in Subclass 3 have interests antagonistic to the class members because they are asserting other claims in addition to their nighttime differential claims.13 However, the defendants do not explain why this would create a conflict of interest, and nothing about the other claims at issue in this action suggests any such conflict. Absent any evident conflict, the defendants' position is without merit. Accordingly, Rule 23(a)(4) is satisfied for Subclasses 2 and 3.

E.

The implied ascertainability requirement is also satisfied for Subclasses 2 and 3, because the members of these Subclasses can be ascertained by reference to the same sorts of objective criteria used to ascertain the members of Subclass 1. See, e.g., Schear, 297 F.R.D. at 125; Morris, 2013 WL 1880919, *6-7.

F.

The plaintiffs must also satisfy the Rule 23(b)(3) predominance and superiority requirements for Subclasses 2 and 3 in order for these Subclasses to be certified.

1.

The defendants do not object to certification of Subclass 3 on predominance grounds. They do argue, however, that Subclass 2 fails to meet the predominance requirement because differences in payroll policies across departments and CBAs will cause individualized issues to predominate over class issues.

With respect to Subclass 2, the predominance requirement is satisfied. Liability on the comp time claims under the NYLL is likely to turn on the classwide issue of whether RiverBay had a corporate policy of paying comp time in lieu of cash wages for overtime hours. If the plaintiffs establish that RiverBay had such a policy, determining whether this resulted in unpaid overtime liability under the NYLL is likely to involve little more than arithmetic. Cf. Schear, 297 F.R.D. at 126. Regardless of how complicated or individualized the calculations become, such mechanical determinations will not overwhelm the litigation. See, e.g., Whitehorn, 275 F.R.D. at 200 (finding the predominance requirement satisfied because "common legal issues related to the members' entitlement to overtime wages and the proper measure of such wages clearly" were not outweighed by "mechanical calculations" relating to overtime hours worked and wages due). Accordingly, the predominance requirement is satisfied for Subclass 2. See Shahriar, 659 F.3d at 253; Niemiec, 2007 WL 5157027, at *12; Noble, 224 F.R.D. at 345.

No challenge has been made to Subclass 3 on predominance grounds, and it is clear that Subclass 3 also satisfies this requirement. The existence of a RiverBay-wide policy of excluding nighttime differential pay when calculating overtime liability is a substantial, classwide question that is at the crux of whether the defendants are liable on the nighttime differential claims. Individualized assessments of whether, and to what extent, application of this policy violated each plaintiff's rights under the NYLL will require little more than arithmetic, and can be made on the basis of payroll records. See Shahriar, 659 F.3d at 253; Schear, 297 F.R.D. at 126; Niemiec, 2007 WL 5157027, at *12; Noble, 224 F.R.D. at 345. Accordingly, Subclass 3 also satisfies the predominance requirement.

2.

Finally, the defendants do not object to certification on superiority grounds, and for the reasons applicable to Subclass 1, the superiority requirement is satisfied for Subclasses 2 and 3. There is a significant number of plaintiffs in each class, there do not appear to be related individual actions pending, and there is a low likelihood that plaintiffs would pursue individual actions if certification were denied. See Katz, 2010 WL 2926196, at *6; Damassia, 250 F.R.D. at 164; Iglesias-Mendoza, 239 F.R.D. at 373.

G.

For the foregoing reasons, the requirements of Rule 23(a) and (b)(3) are satisfied for Subclasses 2 and 3, and the plaintiffs' motion to certify these Subclasses is therefore granted.

CONCLUSION

The Court has considered all of the arguments of the parties. To the extent not specifically addressed above, the remaining arguments are either moot or without merit. For the reasons explained above, the plaintiffs' motion for class certification is granted. The Clerk is directed to close Docket No. 129.

The plaintiffs should provide a proposed order for class notice by August 15, 2014. The defendants may provide any objections and response by August 29, 2014.

SO ORDERED.
