The fluctuating workweek ("FWW") method is one way of calculating overtime compensation that satisfies the requirements of the Fair Labor Standards Act ("FLSA"). See
The district court held that Saybolt's payment scheme violated the FLSA, but the violation was not willful. The district court adopted the plaintiffs' model for calculating damages after concluding that Saybolt was judicially estopped from challenging this model. The district court also awarded liquidated damages. We affirm the district court's conclusions as to liability and willfulness, reverse the district court's ruling on estoppel and its calculation of damages, vacate the district court's order on liquidated damages, and remand for reconsideration of the liquidated damages award and for reconsideration of its calculation of damages in accordance with this opinion and entry of an appropriate judgment.
BACKGROUND
I. Saybolt's Payment Scheme and the FWW Method
The FLSA requires that nonexempt employees receive an overtime premium of not less than one and one-half times their "regular rate of pay" for each hour worked over 40 hours in a given workweek.
A second group of Saybolt inspectors ("the FWW inspectors") received overtime compensation under the FWW method. Federal regulations state that this method is appropriate when an employee works hours that fluctuate from week to week and the employee agrees that a fixed weekly salary will constitute straight-time pay (i.e., non-overtime pay) for all the hours worked in a week, however many or few. See
Calculation of overtime premiums under the FWW method is different from the standard FLSA method in several respects. First, the "regular rate" under the FWW method is determined by dividing the weekly base salary by the total number of hours an employee actually works during the week. This is an application of the principle that the "regular rate" equals the weekly salary divided by "the number of hours which the salary is intended to compensate." See id . § 778.113(a). In the FWW context, "the salary is intended to *922compensate" all hours an employee actually works. Because the hours actually worked each week fluctuate, the "regular rate" under the FWW method will fluctuate from week to week as well. See
Another key difference under the FWW method is that the "overtime rate" is one-half, instead of one and one-half, times the "regular rate." See
Under Saybolt's payment scheme, FWW inspectors were purportedly paid overtime under the FWW method. But the company also paid incentive payments for working on a scheduled day off ("day-off pay"), working at sea ("offshore pay"), and working on a scheduled holiday ("holiday pay"). Non-FWW inspectors were ineligible for these incentives. When calculating the "regular rate," Saybolt added weekly incentive payments to the weekly base salary. Therefore, if a FWW inspector had a weekly base salary of $600, earned $150 in incentive payments, and worked a 60-hour workweek, the "regular rate" for that week would be $12.50 per hour ($600 base salary plus incentive payments of $150 for a total of $750 divided by the 60 hours worked). The "overtime rate" would be $6.25 per hour (one half times the $12.50 "regular rate"), resulting in an overtime premium of $125 (20 overtime hours times the $6.25 "overtime rate"). The FWW inspector's total compensation for the 60-hour week would be $875 ($600 base salary plus $150 incentive pay plus $125 overtime premium).
II. Saybolt's Legal Advice
Saybolt communicated with outside counsel to assess whether the FWW method allowed for additional incentive payments. In May 2009, Saybolt contacted attorney Robert Ivey. Ivey counseled Saybolt that combining incentive payments with the FWW method was a "potential issue." Ivey explained that several district courts and the First Circuit had concluded that paying hours-based premiums in addition to a weekly salary precluded the use of the FWW method. But Ivey also explained that the Fifth Circuit had not addressed the question and that the Department *923of Labor ("DOL") had issued proposed regulations in 2008 that would allow the payment of incentives under the FWW method.
Saybolt contacted Joseph Maddaloni, another outside attorney, in January 2010. Saybolt forwarded Ivey's recommendation to Maddaloni and said that it was "seeking a final opinion and recommendation in order to bring closure to this pay practice." Maddaloni said he disagreed with the court decisions rejecting the use of incentive payments under the FWW method. But Maddaloni conceded that the judges involved were well respected and that a New Jersey district court would likely find their reasoning persuasive. Maddaloni concluded that "while I have always taken the position that Saybolt's use and application of the FWW was defensible, I am concerned that under the present state of the law and the facts that may no longer hold true." Maddaloni later testified that he had considered the law on this issue to be unsettled.
III. Proceedings in the District Court
In January 2010, Joseph Dacar, on behalf of Saybolt inspectors paid under the FWW method, filed a collective action complaint in the Eastern District of North Carolina. A year later, the case was transferred to the Southern District of Texas, and the plaintiffs filed an amended complaint, alleging that (1) Saybolt did not comply with the requirements for using the FWW method and (2) Saybolt willfully violated the FLSA. The complaint also substituted Lyle Deroche and Felton Ravia as named plaintiffs in place of Dacar. The district court conditionally certified a collective action in June 2011, and a total of 112 employees and former employees opted into the case.
In January 2013, the parties filed cross-motions for summary judgment. Saybolt moved for partial summary judgment on the issue of willfulness; the plaintiffs moved for summary judgment on willfulness, liability, damage calculation, and liquidated damages. In August 2014, the district court granted Saybolt's motion and held that Saybolt's violation, if any, was not willful. The plaintiffs moved for reconsideration.
In December 2015, the district court denied the plaintiffs' motion for reconsideration but granted, in part, their motion for summary judgment. The district court held that Saybolt had violated the FWW method because the plaintiffs were not paid a "fixed salary," that liquidated damages were appropriate, and that damages should not be offset by the incentive payments the plaintiffs already received.
In December 2016, the district court held a hearing on damages. The district court asked the parties to brief any remaining issues related to the damages calculation. Saybolt's brief contended that the "regular rate" for calculating overtime damages should be based on the plaintiffs' hours actually worked-not on a 40-hour workweek-and that overtime hours should be multiplied by one half-not one and one-half-times that "regular rate." The district court held that Saybolt was judicially estopped from contesting the appropriate damages model and ordered damages of $3,020,813.21 plus an equal amount in liquidated damages.
The plaintiffs timely appealed the district court's partial grant of summary judgment on Saybolt's willfulness. Saybolt cross-appealed the district court's summary judgment on liability and damages.

DISCUSSION
I. Liability
As explained above, the FLSA generally requires that employees be paid an overtime premium of one and one-half times the "regular rate of pay" for all hours worked in excess of the 40-hour workweek.
(1) the employee's hours must fluctuate from week to week;
(2) the employee must receive a fixed salary that does not vary with the number of hours worked during the week (excluding overtime premiums);
(3) the fixed amount must provide compensation every week at a regular rate at least equal to the minimum wage; and
(4) the employer and employee must share a clear mutual understanding that the employer will pay the fixed salary regardless of the number of hours worked.
Brantley v. Inspectorate Am. Corp. ,
The case against Saybolt is simple: the FWW method requires a fixed weekly salary that does not vary by the number of hours worked, and Saybolt's incentive payments caused weekly variance in the FWW
*925inspectors' straight-time pay.
In O'Brien v. Town of Agawam , the First Circuit squarely addressed this issue and found that payment of "additional compensation" for nighttime shifts in addition to a fixed weekly base salary failed to comply with the FWW method.
Indeed, despite the proposed regulations that Saybolt relied on, the DOL ultimately decided against the amendment in 2011 and issued a final rule stating that incentive payments are "incompatible with the fluctuating workweek method" and that it would not "be appropriate to expand the use of this method of computing overtime pay beyond the scope of the current regulation." See Updating Regulations Issued Under the Fair Labor Standards Act,
Saybolt relies on two decisions to support its payment scheme. Both cases are readily distinguishable. First, Saybolt notes that in Aiken v. County of Hampton , a district court affirmed the compatibility of the FWW method with additional "holiday pay" bonuses.
Second, Saybolt contends that the First Circuit's recent decision in Lalli v. General Nutrition Centers, Inc. , undermines O'Brien by holding that the payment of *926additional commissions is compatible with the FWW method.
In sum, we hold that Saybolt failed to comply with the FWW method, and, therefore, its use of that method to calculate the FWW inspectors' overtime premiums was erroneous.
II. Willfulness
If a plaintiff can demonstrate that a defendant's violation of the FLSA was willful, then the limitations period is extended from two to three years. See
Evidence that a defendant was merely negligent regarding FLSA requirements is insufficient to show willfulness. See Steele v. Leasing Enters.,Ltd. ,
The plaintiffs contend that the legal opinions of Ivey and Maddaloni cast doubt on the continuing viability of Saybolt's payment procedure. But both attorneys also communicated that the legal landscape was unsettled even if courts within the First Circuit would likely rule against Saybolt's payment method. The plaintiffs also cite the existence of a 2009 lawsuit in New York regarding the legality of Saybolt's pay practices. See Lauer v. Saybolt LP , No. 09-CV-3442,
*927In sum, the plaintiffs offer no evidence from which a court could infer that Saybolt willfully violated the FLSA. This conclusion does not mean that an absence of controlling authority or reliance on advice of counsel or the existence of proposed regulations necessarily preclude a willfulness determination. But in this case, all three countervailing considerations are present, and the plaintiffs have not created an issue of disputed fact regarding Saybolt's willfulness.
III. Judicial Estoppel
The district court held that Saybolt was judicially estopped from challenging the methodology used to calculate overtime damages. The doctrine of judicial estoppel is appropriate when (1) a party has asserted a position that is plainly inconsistent with a previously asserted position, (2) the earlier position was accepted by the court, and (3) the party did not act inadvertently. Reed v. City of Arlington ,
Before the district court entered summary judgment, Saybolt suggested that damages, if any, should be based on what the plaintiffs would have earned under a non-FWW payment scheme. Saybolt's own non-FWW inspectors would serve as comparators. Because non-FWW inspectors were not eligible for incentive payments, Saybolt argued that any incentives the plaintiffs earned should offset the damages or, at least, should not be included in the "regular rate" used to calculate damages.
At summary judgment, the district court rejected the non-FWW comparator model by holding that incentive payments must be included in the "regular rate" calculation and could not offset damages. The court did not otherwise determine how damages would be calculated. Almost a year later, the district court held its hearing on damages and asked for final briefing on the issue. Saybolt's brief argued that the FWW method should be used to calculate damages. That is, the "regular rate" should be calculated by dividing total compensation (base salary plus incentives) by all the hours actually worked by the plaintiffs and that the "overtime rate" for calculating damages should be one-half times the "regular rate." The district court held that Saybolt was judicially estopped from making these arguments because Saybolt had previously argued that the "regular rate" for damage calculation could be based on a 40-hour workweek and that the plaintiffs could receive an "overtime rate" of one and one-half times that "regular rate." We disagree.
Saybolt's initial position-that damages should be calculated using non-FWW inspectors as comparators-was not plainly inconsistent with its subsequent argument that damages should be calculated under the FWW method. Cf. Hall v. GE Plastic Pac. PTE Ltd. ,
Nor did the district court accept Saybolt's initial position as is required for judicial estoppel. Indeed, the court rejected the comparator model by requiring that incentive payments be included in the *928"regular rate" calculation. This is why Saybolt fell back on the alternative argument that, since incentive payments must be included, the FWW method should be used to calculate the plaintiffs' damages. Accordingly, the district court erred in holding that Saybolt was judicially estopped from challenging the plaintiffs' damages model.
IV. Damages
An employer who violates the FLSA's overtime requirements is "liable to the employee or employees affected in the amount of ... their unpaid overtime compensation."
Because judicial estoppel does not prevent Saybolt from challenging the plaintiffs' model, we may consider the alternative models that Saybolt has proposed. To begin with, we note that this is a difficult case in which to estimate the plaintiffs' "unpaid overtime compensation." It is not a misclassification case in which the plaintiffs were never paid overtime at all. See, e.g., Hills v. Entergy Operations, Inc. ,
Saybolt proposes that the Court assess damages by looking to its non-FWW comparator inspectors. However, Saybolt has not thoroughly argued this method of damages on appeal or explained how the non-FWW comparators provide a sufficient empirical basis to make the damages model feasible.
Saybolt's fallback damages methodology contains two separable elements: (1) the "regular rate" should be calculated using a denominator of all hours actually worked and not a hypothetical 40-hour denominator and (2) the plaintiffs should receive only one-half times this "regular rate" instead *929of the one and one-half times awarded by the district court.
DOL regulations and relevant case law establish that the "regular rate" should be calculated based on the number of hours the plaintiffs' salary was intended to compensate. There is no 40-hour "default" for calculating the "regular rate," as the plaintiffs suggest. To the contrary, DOL regulations state that the "regular rate" is "determined by dividing [an employee's] total remuneration for employment ... in any workweek by the total number of hours actually worked by him in that workweek for which such compensation was paid ."
Here, the record is unequivocal that the plaintiffs' hours varied from week to week and that they received the same base salary (plus incentives) regardless whether they worked 25 or 65 hours. Under these circumstances, it does not matter that the FWW regulations are inapplicable. For instance, in Singer , the firefighter plaintiffs worked 120 hours in one 14-day pay period and 96 hours in the next.
The plaintiffs cite several cases to support the district court's use of a hypothetical 40-hour divisor, but these are distinguishable or unpersuasive. See Yourman v. Dinkins ,
We agree with the district court's conclusion that plaintiffs are entitled to an award of one and one-half times the "regular rate" instead of using the one-half multiplier that Saybolt claims is appropriate. Use of the one-half multiplier depends on whether the employer establishes that the FWW method of compensation is appropriate under the regulation. See
In Singer , we held that the FWW method did not apply because the employer failed to establish one of the four requirements for its application. Singer ,
The fire fighters correctly observe that the fluctuating method would be inappropriate in this case. An employer can use this method only if the employer and employee have a "clear mutual understanding" that the method applies. 29 C.F.R. 778.114(a) ; Heder v. City of Two Rivers, Wisconsin ,295 F.3d 777 , 780 ; Valerio v. Putnam Assoc. Inc. ,173 F.3d 35 , 39 (1st Cir.1999). In this case, neither party has presented evidence of such a "clear mutual understanding."
However, the fire fighters are incorrect to say that the district court applied the fluctuating method in this case. The district court did not calculate the fire fighters' damages by multiplying their overtime hours by one-half of their regular rate of pay. Instead, the district court multiplied the fire fighters' overtime hours (i.e., the hours exceeding 106 in a 14-day work period) by one-and-one half of their regular rate of pay. The district court thus used the usual method of calculating overtime pay, not the less common fluctuating method. See29 C.F.R. § 778.107 ("The general overtime pay standard ... requires that overtime must be compensated at a rate not less than one and one-half times the regular rate at which the employee is actually employed[.]").
Additionally, in O'Brien , the First Circuit rejected the district court's conclusion that the employer there had properly calculated police overtime in accordance with the FWW.
We find nothing in the facts of today's case to warrant a departure from the general rule that the one-half multiplier can be used only in connection with a qualified FWW payment method that meets each of the regulatory requirements. See
Because Saybolt failed to pay its workers a "fixed salary," we must also conclude that one and one-half is the applicable multiplier for calculating the proper amount of overtime pay owed. Accordingly, the district court did not err in using the one and one-half multiplier. Because we determine here that the appropriate denominator for calculating the regular rate includes all hours intended to be compensated, applying the one and one-half multiplier is not a windfall to the plaintiffs. It is merely the ordinary calculation of overtime mandated by the FLSA. See
V. Liquidated Damages
The FLSA provides that liquidated damages be awarded for FLSA violations in an amount equal to the actual damages.
To prove the reasonableness of its conduct, Saybolt repeats the reasons that its conduct was not willful. Saybolt suggests that the district court's willfulness determination precludes the award of liquidated damages. This fails to account for the fact that the evidentiary burden has shifted. Indeed, this court has held that, "[e]ven if the district court determines that the employer's actions were taken in good faith and based on reasonable grounds, the district court still retains the discretion to award liquidated damages." Heidtman v. Cty. of El Paso ,
*932Nevertheless, because the district court erred in adopting the plaintiffs' damages methodology, we must vacate the liquidated damages award and remand for the district court to determine whether liquidated damages remain appropriate.
CONCLUSION
For the foregoing reasons, we: (1) affirm the judgment of the district court on liability and willfulness; (2) reverse the district court's ruling on estoppel and its calculation of damages; (3) vacate the district court's order on liquidated damages; (4) remand for reconsideration of the liquidated damages award; and (5) remand for calculation of damages
EDITH H. JONES, Circuit Judge, concurring and dissenting:
Although I agree with the per curiam opinion's discussion of liability and willfulness in this FLSA case, and I agree with requiring the use of hours actually worked for purposes of damages, I would reverse the overtime rate calculation on different grounds from those stated by the majority. The majority's proposed formula effects an illegal windfall for the plaintiffs, contrary to the Supreme Court and this court. I would remand for the district court to calculate damages using the FWW weekly wage actually paid by Saybolt, adding one-half times the hourly rate for each hour a plaintiff worked in excess of 40 hours. The majority's formulation, which affords a one-and-a-half hourly multiplier for overtime, overcompensates the plaintiffs. The majority fail to recognize the plaintiffs have already been paid, under the FWW method, a higher rate for weeks in which they worked less than 40 hours.
The majority premises this result on DOL's April 2011 final rule and on this court's decision in Singer . Neither rationale holds water. Using the 2011 rule to impose damages on Saybolt before the final rule was promulgated is unfair. Worse, it confuses liability and damages. It is one thing to conclude that the case law did not support Saybolt's methodology before the 2011 rule came into force; it is another to retroactively apply the rule for the purpose of calculating damages.
Under the circumstances of this case, the majority's invocation of time-and-a-half for overtime contravenes the principle that the purpose of actual damages under the FLSA is to compensate employees for unpaid overtime-it is not to punish employers. Even a finding of willfulness does not impose exemplary damages on employers but merely lengthens the limitations period from two years to three. See
When the FLSA's purpose in awarding actual damages is faithfully followed, it is apparent that the one-half multiplier for overtime hours sufficiently compensates the plaintiffs here. The one-half multiplier is more closely tied to Saybolt's attempt to invoke the FWW method. The FWW method's logic is that, where the employees agreed to receive a fixed salary for all hours worked in a pay period, and the actual hours worked varied below and above 40/week, then they have already received straight-time pay for their overtime and should receive only an additional one-half the "regular rate" for each overtime hour. See
The majority erroneously rely on two cases in an attempt to support their damage formula. As regards the FWW method, however, the footnote in Singer v. City of Waco,
It is also significant that in Singer, the court approves offsetting the time-and-a-half time owed for the firemen's "long" weeks by the amounts they were overcompensated *934for every third "short" week. See Part VII of Singer,
Finally, the majority miscite the First Circuit's O'Brien decision as supporting the incorrect damage methodology. O'Brien v. Town of Agawam,
For these reasons, I respectfully dissent from that part of the majority opinion which holds Saybolt liable for the punitive imposition of time-and-a-half compensation under the circumstances of this case.
Likewise, if the same employee worked only 20 hours, the FWW method would yield a "regular rate" of $30.00 per hour for that week.
These hypothetical calculations do not reflect the actual wages earned by either the FWW or non-FWW inspectors. Saybolt suggests that the total compensation for non-FWW inspectors did not differ significantly from that of FWW inspectors. This conclusion is reasonable: non-FWW inspectors would have been paid a much larger overtime premium (especially for longer workweeks), but they received no incentive pay.
At summary judgment, the plaintiffs also argued that Saybolt had failed to satisfy the fourth requirement because there was no "clear mutual understanding" that their salaries covered all hours worked. The district court pretermitted this question after finding that Saybolt violated the "fixed salary" requirement.
As a threshold matter, the plaintiffs claim that Saybolt waived the argument that it paid a "fixed salary" by failing to raise it at summary judgment. On the contrary, Saybolt's response to the plaintiffs' summary judgment motion stated that there were "genuine issues of fact as to whether Plaintiffs received a fixed amount as straight-time pay." The district court discussed and ruled on the question.
The plaintiffs also claim that Saybolt failed to pay a "fixed salary" by making impermissible deductions from inspectors' weekly salaries when they took time off. The plaintiffs provide no evidence that these deductions were actually made from the plaintiffs' salaries. Payment records demonstrate that sick or vacation pay would be used bump up inspectors' weekly wage to ensure a fixed weekly amount.
Several district courts have followed O'Brien in finding that additional incentive payments can invalidate the use of the FWW method. See Hanson v. Camin Cargo Control, Inc. ,
We likewise reject the plaintiffs' claims (1) that Saybolt waived its challenges to the damages model and (2) that the invited error doctrine bars these arguments. Regarding waiver, Saybolt pressed the arguments made on appeal multiple times before the entry of final judgment; they were thus properly presented to the court. See Keenan v. Tejeda ,
The 40-hour divisor-as opposed to using hours actually worked-augments the "regular rate" because an employee is only owed overtime when she actually works more than 40 hours. Thus, when calculating overtime compensation, using the hypothetical 40-hour divisor will always result in a larger "regular rate."
Because this damages model has not been adequately briefed, we leave for another day whether such a model, or any other damages model, may be appropriate in cases in which an employer fails to satisfy the requirements allowing use of the FWW method.
Though the First Circuit remanded the case to the district court to calculate the actual overtime owed, the reasoning in the opinion did not give the district court discretion to apply the one-half multiplier because, as the court found, § 788.114 did not apply. See id. at 287-90.
As set forth above, a plaintiff is entitled to overtime pay for any week in which he worked in excess of 40 hours. To determine the amount of overtime compensation due, the district court should first determine a plaintiff's regular hourly rate of pay by dividing the total amount of remuneration paid in a workweek (including incentive payments ) by the total number of hours intended to be compensated (which, in this case, is the total number of hours actually worked) in that workweek. See
Consequently, there is significant logical appeal to Saybolt's initial proposal that the court should assess damages by looking to its non-FWW comparator inspectors. Saybolt acknowledges that this would be a novel method of calculating damages, but here the method seems to fit: the plaintiffs say they should not have been paid under the FWW method, and the non-FWW comparators' wages could demonstrate how the plaintiffs would have been paid absent the mistake. Saybolt, however, has not thoroughly argued this method of damages on appeal or explained how the non-FWW comparators provide a sufficient empirical basis to make the damages model feasible.
