Sandra ELLIS, on behalf of herself and others similarly situated, Plaintiff-Appellant, v. J.R.'S COUNTRY STORES, INC., a Colorado corporation, Defendant-Appellee, 779 F.3d 1184

HOLMES, Circuit Judge. Sandra Ellis appeals from the district court’s grant of

summary judgment in favor of J.R.’s Country Stores, Inc., her former employer, on her claim for violation of the Fair Labor Standards Act of 1938 (“FLSA”), 29 U.S.C. § 207. Our jurisdiction arises under 28 U.S.C. § 1291, and we affirm. I We offer at the outset an overview of the applicable statutory framework. We then provide the factual background and procedural history of this case, reciting all

summary-judgment evidence in the light most favorable to Ms. Ellis as the nonmov-ant. See Salazar v. Butterball, LLC, 644 F.3d 1130, 1136 (10th Cir.2011); Gwinn v. Awmiller, 354 F.3d 1211, 1215 (10th Cir. 2004). A Congress enacted the FLSA in order to “protect all covered workers from substandard wages and oppressive working hours, ‘labor conditions [that are] detrimental to the maintenance of the minimum standard of living necessary for health, efficiency and general well-being of workers.’ ” Barrentine v.

Arkansas-Best Freight Sys., Inc., 450 U.S. 728, 739, 101 S.Ct. 1437, 67 L.Ed.2d 641 (1981) (alteration in original) (quoting 29 U.S.C. § 202(a)); see Chavez v. City of Albuquerque, 630 F.3d 1300, 1304 (10th Cir.2011) (“The purpose of FLSA overtime is ‘to compensate those who labored in excess of the statutory maximum number of hours for the wear and tear of extra work and to spread employment through inducing employers to shorten hours because of the pressure of extra cost.’ ” (quoting Bay Ridge Operating Co. v. Aaron, 334 U.S. 446, 460, 68 S.Ct. 1186, 92 L.Ed. 1502 (1948))).

The FLSA effectuates this purpose by “generally requiring] an employer to pay its employees at a rate of one and one-half times their regular rate of pay for any time worked in excess of forty hours in a given workweek.” Archuleta v. Wal-Mart Stores, Inc., 543 F.3d 1226, 1228 (10th Cir.2008); accord Albers v. Bd. of Cnty. Comm’rs, 771 F.3d 697, 699 (10th Cir.2014). In other words, the statute provides for overtime pay in specified circumstances. See 29 U.S.C. § 207(a)(2).

If an employee satisfies her burden of “proving] that the employer is violating the FLSA,” Archuleta, 543 F.3d at 1233, she may be entitled to recoup unpaid overtime compensation and liquidated damages, see 29 U.S.C. § 216(b). But despite “the remedial nature of [the] FLSA,” Pacheco v. Whiting Farms, Inc., 365 F.3d 1199, 1206 (10th Cir.2004), “not all workers require[] the same kind of protection” under the statute, Ackerman v. Coca-Cola Enters., Inc., 179 F.3d 1260, 1263 (10th Cir.1999).

Notably, as is relevant here, “employee[s] employed in a bona fide executive, administrative, or professional capacity ... as such terms are defined ... by regulations of the Secretary [of Labor],” 29 U.S.C. § 213(a)(1), are exempt from the FLSA’s requirements and are thus ineligible for overtime compensation. These regulations “are entitled to judicial deference and are the primary source of guidance for determining the scope of exemptions to the FLSA.” Ackerman, 179 F.3d at 1264 (internal quotation marks omitted). Exercising its delegated authority on behalf of the U.S.

Department of Labor (“DOL”), the Secretary of Labor (“Secretary”) has promulgated several implementing regulations for the FLSA, one of which defines the term “employee employed in a bona fide executive capacity” as an employee who is:

(1) Compensated on a salary basis at a rate of not less than $455 per week ...;

(2) Whose primary duty is management of the enterprise in which the employee is employed or of a customarily recognized department or subdivision thereof;

(3) Who customarily and regularly directs the work of two or more other employees; and

(4) Who has the authority to hire or fire other employees or whose suggestions and recommendations as to the hiring, firing, advancement, promotion or any other change of status of other employees are given particular weight. 29 C.F.R. § 541.100(a); accord Maestas v. Day & Zimmerman, LLC, 664 F.3d 822, 827 (10th Cir.2012). Pursuant to the FLSA’s regulatory framework, an employee must be paid on a salary basis to satisfy the requirements of an “executive” exempt from the statute’s overtime requirements. See Auer v.

Robbins, 519 U.S. 452, 455-56, 117 S.Ct. 905, 137 L.Ed.2d 79 (1997); In re Wal-Mart Stores, Inc., 395 F.3d 1177, 1180 (10th Cir.2005). “An employee -will be considered to be paid on a ‘salary basis’ ” under the Secretary’s regulations if she “regularly receives each pay period on a weekly, or less frequent basis, a predetermined amount constituting all or part of [her] compensation, which amount is not subject to reduction because of variations in the quality or quantity of the work performed.” 29 C.F.R. § 541.602(a).

As we have explained, “[s]ince exempt employees are not paid by the hour, the FLSA’s implementing regulations prohibit employers from docking their pay for working less than a full eight-hour day.” McBride v. Peak Wellness Ctr., Inc., 688 F.3d 698, 705 (10th Cir.2012). We are obliged to interpret this “executive” exemption narrowly against employers. See Chessin v.

Keystone Resort Mgmt., Inc., 184 F.3d 1188, 1192 (10th Cir.1999) (“In a case involving the FLSA, an employer bears the burden of proving ... the applicability of an FLSA exemption; we must construe the exemption narrowly against the employer.”); Aaron v. City of Wichita, 54 F.3d 652, 657 (10th Cir.1995) (“Exemptions to the FLSA are to be narrowly construed.... An employer must prove that the employee is exempt by ‘clear and affirmative’ evidence.” (citation omitted) (quoting Donovan v. United Video, Inc., 725 F.2d 577, 581 (10th Cir.1984))).

An employer may lose the right to treat otherwise eligible employees as exempt “executives” in certain situations. For instance, “[a]n employer who makes improper deductions from salary shall lose the exemption if the facts demonstrate that the employer did not intend to pay employees on a, salary basis.” 29 C.F.R. § 541.603(a) [hereinafter “subsection (a)”].

Whether an employer making such improper deductions should be deemed not to have intended to pay on a salary basis turns on whether the employer has an “actual practice of making improper deductions,” id., as opposed to a “theoretical possibility of such deductions,” McBride, 688 F.3d at 705.

The Secretary has provided guidance in that regard, namely by detailing five applicable factors for courts to consider: The factors to consider when determining whether an employer has an actual practice of making improper deductions include, but are not limited to: the number of improper deductions, particularly as compared to the number of employee infractions warranting discipline; the time period during which the employer made improper deductions; the number and geographic location of employees whose salary was improperly reduced; the number and geographic location of managers responsible for taking the improper deductions; and whether the employer has a clearly communicated policy permitting or prohibiting improper deductions. 29 C.F.R. § 541.603(a).

On the face of subsection (a), it is evident that one variable which may inform courts as to the existence vel non of an “actual practice of making improper deductions” is whether the employer has promulgated a “clear[ ]” policy concerning improper deductions. Id. The Secretary provides helpful explication regarding this final salary-basis-test factor in another subsection of the same regulation, noting that a “clearly communicated policy” is one “that prohibits the improper pay deductions specified in [subsection] (

a) and includes a complaint mechanism.” Id. § 541.603(d) [hereinafter “subsection (d)”]. Further, according to subsection (d): [t]he best evidence of a clearly communicated policy is a written policy that was distributed to employees prior to the improper pay deductions by, for example, providing a copy of the policy to employees at the time of hire, publishing the policy in an employee handbook or publishing the policy on the employer’s Intranet. Id.

In sum, under the rubric of subsection (a)—as informed by subsection (d)—“if the facts demonstrate that” the employer maintained “[a]n actual practice of making improper deductions,” the default conclusion is that the employer “shall lose the exemption.” Id. § 541.603(a) (emphasis added). The employer is stripped of the exemption because its “actual practice” of improperly deducting pay vitiates the intent to pay a salary under the salary-basis test. See id.

Consequently, when the facts so indicate, “the exemption is lost during the time period in which the improper deductions were made.” Id. § 541.603(b); accord Baden-Winterwood v. Life Time Fitness, Inc., 566 F.3d 618, 628 (6th Cir.2009).

However, the Secretary has carved out a savings provision for “[improper deductions that are either isolated or inadvertent,” which allows the exemption to stand “if the employer reimburses the employees for such improper deductions.” 29 C.F.R. § 541.603(c) [hereinafter “subsection (c)”]; see Archuleta, 543 F.3d at 1235 (discussing an employer’s attempt to “take advantage of’ this savings provision “by reimbursing its pharmacists for the times it paid them less than their guaranteed minimum salary”).

As a practical matter, “[t]he ‘window of correction’ provided by [subsection (c) ] allows employers to treat otherwise eligible employees as salaried, regardless of the employer’s one-time or unintentional failure to adhere to [the] requirements” of the salary-basis test set forth in subsection (a). Spradling v. City of Tulsa, 95 F.3d 1492, 1503 (10th Cir.1996). B Having explained the legal standards material to the disposition of this appeal, we proceed to the salient background facts, viewed in the light most favorable to Ms. Ellis.

J.R.’s Country Stores, Inc. (“J.R.’s” or “the Company”) is a chain of convenience markets located throughout Colorado. Its individual shops, which sell gas, groceries, and sundries, are operated by store managers. As set forth in the Company’s Store Manager Base Pay Plan (“the Pay Plan”), each manager is considered a “salaried employee” and is expected to work “a minimum of 50 hours per week and a minimum 5 day work week.” Aplt.App. at 378 (2011 Pay Plan, filed Jan. 11, 2013). The Company also requires every store manager to “work whatever number of hours per week is necessary to effectively run [her] store.” Id.

In December 2007, Ms. Ellis began working as the manager of a J.R.’s store in Holly, Colorado. The Company classified her as an exempt, salaried employee and paid her $600 on a weekly basis (an amount that increased to $625 in February 2011), as well as a monthly bonus commensurate with her store’s performance. While Ms. Ellis was employed in this capacity, she generally worked fifty-hour (and sometimes closer to sixty-hour) weeks, which was consistent with the terms of the Pay Plan. On April 3, 2012, Ms.

Ellis received a paycheck in the amount of $593.80, instead of the $625 she customarily earned in a pay period. The Company had deducted $31.20 from that paycheck because for the work week of March 16 to March 22, 2012, Ms. Ellis reported having worked only 40.91 hours of the requisite fifty. More specifically, Ms. Ellis “missed less than a full day of work [that week].” Aplt. Opening Br. at 5. This was the only instance during Ms. Ellis’s tenure with the Company that she received less than her typical, predetermined pay. Ms. Ellis resigned on April 6, 2012.

Soon afterward, she sent the Company a letter “claiming] that she [was] owed $42,187.50 in unpaid overtime wages.” ApltApp. at 284 (Letter, dated May 18, 2012). In lodging that request, Ms. Ellis opined that she had “lost her exempt status under the [FLSA] ... when J.R.’s made a one-time deduction from [her] pay for not working fifty hours during a workweek,” which, in turn, entitled her to three years’ worth of retroactive overtime pay. Id. This was the correct result, according to Ms. Ellis, because the paycheck in question demonstrated a “willful” “practice of making improper deductions” by the Company.

Id. (internal quotation marks omitted). The Company initially denied both that this singular deduction was improper and that it constituted an actual practice of improper deductions under the applicable regulatory provisions. Nonetheless, the Company informed Ms. Ellis by letter that it would “take the high road ... and pay [her] for the overtime she worked during the time period in which the deduction occurred.” Id. at 285 (internal quotation marks omitted).

To explain the amount of the accompanying check, $332.88-which was more than ten times the amount of the deduction—the Company stated: During the workweek in which the deduction was made, [you] worked a total of 56.42 hours.... [Your] hourly rate was $12.50, meaning [your] overtime rate is $18.75. [Your] $625 weekly salary was based on a fixed 50 hour workweek. By reimbursing [you] the $150 that was deducted ..., J.R.’s has now made [you] whole for that workweek and has therefore paid [you] for the first 50 hours for purposes of the overtime calculation.

What remains is (1) [your] regular pay for the additional 6.42 hours, and (2) the “and a half’ for the 16.42 hours of overtime. Therefore, the calculation is as follows: (1) 6.42 hours x $12.50 (regular time) = $80.25 (2) 16.42 hours x $6.25 (half time) = $102.63 Total = $182.88. Therefore, on behalf of J.R.’s, enclosed please find a check ... in the amount of $332.88 ($150 + $182.88). Id. (emphasis omitted) (footnote omitted).

The Company further noted that it had “use[d] the hours worked during the March 23, 2012 workweek for purposes of the overtime calculation” for two reasons: (1) to comport with the regulatory language “during the time period in which the [deduction was] made,” 29 C.F.R. § 541.603(b); and (2) to produce “a more favorable calculation for” Ms. Ellis. Aplt. App. at 285 n. 2. It did so even though the deduction at issue “was made based on the number pf hours [Ms. Ellis] worked in the previous workweek”—40.91 hours. Id. (emphasis added). On July 23, 2012, Ms.

Ellis filed a lawsuit against her former employer in the United States District Court for the District of Colorado, bringing one claim under the FLSA. Alleging that her “compensation was reduced when she did not work at least 50 hours” per week, Ms. Ellis urged that she “was not an exempt employee [under the FLSA] because she was not paid on a true salary basis.” Id. at 11 (Compl., filed July 23, 2012). Thus, reasoned Ms.

Ellis, the Company’s failure to classify her as an hourly employee entitled her to recoup retroactive overtime pay “for all hours worked in excess of forty hours in a single work week” during her term of employment. Id. at 12. Ms. Ellis also signaled her intent to certify a class of similarly situated store managers. The Company filed a motion for

summary judgment, attaching as exhibits all time sheets and payroll records pertaining to Ms. Ellis’s employment. Instead of responding to the Company’s motion, Ms. Ellis filed a “Motion to Certify Conditionally a Collective Action Under the [FLSA] and for Court Assisted Notice,” id. at 289 (Mot. to Certify, filed Oct. 18, 2012) (capitalization altered), and, shortly thereafter, also a motion to deny or defer judgment under Federal Rule of Civil Procedure 56(

d) so that she could “reasonably engage in discovery sufficient to rebut a motion for

summary judgment,” id. at 314 (Mot. to Den. or Defer J., filed Oct. 31, 2012) (capitalization altered). For its part, the Company then sought a temporary stay of class certification, pending the district court’s

summary-judgment determination. The district court, in an order dated December 11, 2012, denied Ms. Ellis’s Rule 56(

d) motion and granted the Company’s motion to stay a class-certification ruling until the court’s decision on the motion for

summary judgment. Consequently, on January 11, 2013, Ms. Ellis filed her response to the Company’s

summary-judgment motion. Then, on July 12, 2013, the district court granted

summary judgment in favor of the Company. The substance of the court’s ruling was twofold. First, the court determined that the undisputed material facts demonstrated the Company’s intent to pay Ms. Ellis a salary and that the one-time pay deduction did not change that intent. Stated otherwise, the district court ruled that the Company’s deduction did not constitute a violation of the salary-basis test. Second, the court reasoned, even if Ms.

Ellis could demonstrate that the Company did not intend to pay her a salary, her FLSA claim would still founder because the Company was entitled to rely on the protection of the window-of-eorrection defense detailed in the FLSA’s implementing regulations. In light of the foregoing findings, the district court awarded

summary judgment to the Company and denied Ms. Ellis’s motion for class certification as moot. The court entered judgment on July 15, 2013, dismissing the lawsuit with prejudice. Ms. Ellis timely appealed from the district court’s judgment. II On appeal, Ms. Ellis challenges the district court’s

summary-judgment order on several fronts. “We review the district court’s

summary judgment decision de novo, applying the same standard as the-district court.” Brammer-Hoelter v. Twin Peaks Charter Acad., 602 F.3d 1175, 1184 (10th Cir.2010); accord Colo. Cross-Disability Coal. v. Abercrombie & Fitch Co., 765 F.3d 1205, 1218 (10th Cir.2014).

Summary judgment is appropriate “if the mov-ant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(a); accord Felkins v. City of Lakewood, 774 F.3d 647, 650 (10th Cir. 2014). As noted above, we “examine the record and all reasonable inferences that might be drawn from it in the light most favorable to the non-moving party”—that is, Ms. Ellis. Merrifield v. Bd. of Cnty. Comm’rs, 654 F.3d 1073, 1077 (10th Cir. 2011) (internal quotation marks omitted).

Moreover, “we can affirm on any ground supported by the record, so long as the appellant has had a fair opportunity to address that ground.” Alpine Bank v. Hubbell, 555 F.3d 1097, 1108 (10th Cir. 2009) (internal quotation marks omitted). Ms. Ellis also seeks review of the district court’s denial of deferment for expanded discovery pursuant to Rule 56(d), which we review for an abuse of discretion. See FDIC v. Arciero, 741 F.3d 1111, 1116 (10th Cir.2013).

We will find an abuse of discretion “when the district court bases its ruling on an erroneous conclusion of law or relies on clearly erroneous fact findings.” Walters v. Wal-Mart Stores, Inc., 703 F.3d 1167, 1172 (10th Cir.2013) (internal quotation marks omitted); accord Trentadue v.

FBI, 572 F.3d 794, 806 (10th Cir.2009). “A finding of fact is clearly erroneous if it is without factual support in the record or if, after reviewing all of the evidence, we are left with the definite and firm conviction that a mistake has been made.” In re Vaughn, 765 F.3d 1174, 1180 (10th Cir.2014) (internal quotation marks omitted). In the Rule 56(

d) context, the party requesting deferral of judgment— here, Ms. Ellis—shoulders the burden of demonstrating an abuse of discretion. See McBride, 688 F.3d at 703. Ill Ms. Ellis presents two overarching questions for our review of the district court’s

summary-judgment ruling: (1) whether the court misapplied the salary-basis test associated with her FLSA exemption (i.e., subsection (a)), and (2) whether the court incorrectly permitted the Company to avail itself of the window-of-correction defense (i.e., subsection (c)) to rectify any improper deduction to her pay. Not surprisingly, Ms. Ellis answers both questions in the affirmative and urges us to find that the district court committed error in awarding

summary judgment to the Company. We are not persuaded by any of Ms. Ellis’s appellate arguments and, in point of fact, find ourselves in substantial agreement with the district court in all respects. Before commencing our substantive discussion, however, we note the Company’s suggestion that we cabin our affirmance to the issue of whether the window-of-correction defense was satisfied. The Company reasons that such an approach “would forestall the need to address most of [Ms.] Ellis’s arguments,” Aplee. Br. at 6—most notably, her contention that the district court’s reading of subsections (

a) and (

c) contravenes settled principles of statutory

interpretation. Although we recognize that, under certain circumstances, the task of reconciling subsections (

a) and (

c) could potentially be difficult, on this record, Ms. Ellis’s statutory-interpretation argument does not give us cause to shrink from our jurisprudentially beneficial plan of comprehensively resolving this dispute. That is because (as more fully explicated below), on this record, the Company can clearly rely on subsections (

a) and (

c) and secure a successful outcome by doing so. More specifically, we conclude that there is no genuine issue of material fact that the Company had no practice or policy of making improper deductions for salaried employees (which effectively resolves the subsection (

a) question in the Company’s favor). And we also determine that the documented improper deduction that the Company made from Ms. Ellis’s paycheck was truly isolated (which effectively gives the Company victory on the subsection (

c) question). Accordingly, for the reasons stated herein, we are satisfied that the district court properly awarded

summary judgment to the Company. A We first address Ms. Ellis’s contention that the district court incorrectly found no genuine issues of material fact concerning the Company’s intent to pay her a salary; instead, reasons Ms. Ellis, the court should have considered her “an hourly employee in every sense.” Aplt. Opening Br. at 20. According to Ms. Ellis, the terms of the Pay Plan ineluctably yield this conclusion.

The Pay Plan, she says, is “unlike any other to be examined by a federal court for conformance to the salary basis test,” id., due to a “combination of unique factors”: a “hard floor” of fifty hours per week, a requirement to log the number of hours worked, and an alleged “stated policy of deducting pay for less than a day’s absence,” Aplt. Reply Br. at 18. For this reason, among others that we address below, Ms. Ellis argues that the district court’s ruling constitutes reversible error. Though Ms.

Ellis strives mightily on multiple fronts to attack the salary-basis aspect of the district court’s decision, we reject each of her arguments. We conclude that the Company did not lose this exemption as regards Ms. Ellis. 1 Under subsection (a), an “actual practice of making improper deductions demonstrates that the employer did not intend to pay employees on a salary basis” and results in the employer’s loss of the executive exemption for those employees. 29 C.F.R. § 541.603(a).

As noted, the Secretary has offered several guideposts for courts confronting this issue: .The factors to consider when determining whether an employer has an actual practice of making improper deductions include, but are not limited to: [1] the number of improper deductions, particularly as compared to the number of employee infractions warranting discipline; [2] the time period during which the employer made improper deductions; [3] the number and geographic location of employees whose salary was improperly reduced; [4] the number and geographic location of managers responsible for taking the improper deductions; and [5] whether the employer has a clearly communicated policy permitting or prohibiting improper deductions.

Id. Ms. Ellis argues that the district court rendered an erroneous decision by focusing exclusively on the first factor of the salary-basis test—the number of improper deductions. We disagree. On the contrary, we believe the district court’s ruling can be fairly read to address all of the salary-basis factors in some appreciable manner. First, the district court noted that the Company “reduced [Ms.

Ellis’s] pay on only one occasion,” ApltApp. at 452, even though—as the time sheets reflected—“[Ms.] Ellis worked less than 50 hours on 13 separate occasions, not counting holidays or days when [she] was sick or on vacation,” id. at 454. Next, with regard to the time period during which the Company made the improper deduction (i.e., the second factor), the court observed that Ms. Ellis’s pay was improperly reduced on April 3, 2012, which impacted one week-long pay cycle.

As to the third and fourth factors, the court stated: [W]ith respect to the number and geographic location of additional employees whose salary was improperly reduced, the Court stayed proceedings on that issue because, having experienced only one allegedly improper deduction, Ellis appeared to lack a viable claim, which could not be salvaged by recourse to evidence relating to other individuals ____[F]or substantially the same reason, the number and geographic location of managers responsible for taking the improper deductions does not support Ellis’s position.

No such “deductions” (plural), occurred—only the singular deduction that Ellis acknowledges. Id. at 456 (internal quotation marks omitted). And, finally, in assessing “whether the [Company] has a clearly communicated policy permitting or prohibiting improper deductions,” 29 C.F.R. § 541.603(a)—that is, the fifth factor—the district court rejected Ms.

Ellis’s assertion, which she made in an affidavit, that the Company’s policy was “not clear,” Aplt.App. at 454 n. 4 (internal quotation marks omitted), and expressly referenced the Company’s policy as set forth in its employee handbook, see id. at 456 (concluding that “[the Company’s] employee handbook contains a written policy” that “clearly communicates that improper deductions are prohibited,” as contemplated by subsection (d)). Because even a brief review of the challenged district court order belies Ms.

Ellis’s assertion that only one component of the salary-basis test—the number of improper deductions—received consideration, this argument does not avail her. We are satisfied by the district court’s cogent reasons offered in applying the test—and, although it disposed of the third and fourth factors summarily, we discern no error in that choice. The court had already scrutinized those factors in its December 11, 2012, ruling on Ms. Ellis’s Rule 56(

d) motion and, absent significant intervening developments, was under no legal obligation to revisit the issues. In any event, as the Company has noted, the fact that “other courts have examined as few as one of the five factors,” Aplee. Br. at 19, strongly militates against a conclusion that the court’s analytical approach here constituted error. See, e.g., McBride, 688 F.3d at 704-05 (arguably only considering the existence vel non of a deduction); Cash v. Cycle Craft Co., 508 F.3d 680, 683-84 (1st Cir.2007) (assessing only the first factor); Mathews v.

Bronger Masonry, Inc., 772 F.Supp.2d 1004, 1012-14 (S.D.Ind.2011) (assessing the first and second factors). All told, the district court’s straightforward application of the salary-basis test affords us no legally cognizable basis to reverse. 2 More broadly, Ms. Ellis disputes the district court’s conclusion that she failed to raise genuine issues of material fact concerning the existence of an actual Company practice or policy of making improper deductions. For the reasons discussed, we find her position unconvincing. a First, Ms.

Ellis argues that the district court incorrectly found no genuine issue of material fact concerning the existence of an actual practice of improper deductions by the Company—and, therefore, no genuine issue of material fact concerning the Company’s intent to pay her on a salary basis. We disagree. After setting out the components of the salary-basis test, the district court determined that the factors to consider when determining whether an employer has an actual practice of making improper deductions, on the record presented, did not prompt a finding that the Company had such a practice.

The court appropriately invoked the Supreme Court’s Auer decision to support its view that the Company’s one-time improper deduction from Ms. Ellis’s pay, “taken under unusual circumstances!, would] not defeat [Ms. Ellis’s] salaried status.” Aplt.App. at 452 (citing Auer, 519 U.S. at 460-61, 117 S.Ct. 905). This is hardly an unusual conclusion in FLSA jurisprudence, and it is the correct result here. See, e.g., Carpenter v.

City & Cnty. of Denver, 115 F.3d 765, 767 (10th Cir.1997) (noting with approval that “although there were two cases of alleged deductions, the [district] [c]ourt specifically recognized that such one time deductions under Unusual circumstances will not oust exempt status and may be remedied”); see also Kennedy v. Commonwealth Edison Co., 410 F.3d 365, 372 (7th Cir. 2005) (discussing subsection (

a) and its predecessor regulation, and concluding that “[i]dentifying a few random, isolated, and negligible deductions is not enough to show an actual practice or policy of treating as hourly the theoretically salaried.... This means that these isolated instances of deductions do not create a genuine issue of fact about the proper characterization of the plaintiffs’ positions.”); Block v. City of L.A., 253 F.3d 410, 415 (9th Cir.2001) (“In some cases, the number of [employer] suspensions alone may be sufficient indicia of the employer’s intent to resolve the ‘actual practice’ determination.

For example, the number may be so small that there would be no way to say that the' employer meant to treat an entire class of employees as hourly rather than salaried by virtue of one or two isolated suspensions.”); Aiken v. City of Memphis, 190 F.3d 753, 762 (6th Cir.1999) (“The evidence shows that only one captain ever faced a deduction in pay. Thus, plaintiffs cannot demonstrate an actual practice of applying such deductions to captains.”).

In affirming the district court on this basis, we note that the regulatory language—which “[is] entitled to judicial deference [as] the primary source of guidance for determining the scope of exemptions to the FLSA,” Ackerman, 179 F.3d at 1264 (internal quotation marks omitted)—cannot be overlooked. We find especially telling the Secretary’s use of the term deductions (rather than deduction) multiple times in the text of the FLSA’s implementing regulations. See generally 29 C.F.R. §§ 541.603(a)-(c). The Supreme Court has instructed that such word choices should be considered deliberate. See, e.g., Hertz Corp. v.

Friend, 559 U.S. 77, 93, 130 S.Ct. 1181, 175 L.Ed.2d 1029 (2010) (finding the fact that “[t]he word ‘place’ is in the singular, not the plural” critical in interpreting the relevant statute); Metro. Stevedore Co. v. Rambo, 515 U.S. 291, 296, 115 S.Ct. 2144, 132 L.Ed.2d 226 (1995) (“The use of ‘conditions,’ a word in the plural, suggests that Congress did not intend to limit the bases for modifying awards to a single condition.”).

Our growing body of FLSA caselaw reflects this understanding of the Secretary’s regulatory focus: we have held that “one change in base- hours [producing a deduction] ... is not the kind of frequent change necessary to create a factual dispute.” Archuleta, 543 F.3d at 1235; see also In re Wal-Mart, 395 F.3d at 1189 (in crafting rule regarding prospective deductions, expressly requiring proof of “frequent” “salary changes ” and “adjustments ” (emphases added)). Along those lines, we find it implausible that subsection (a)’s requirement of a “practice” of such deductions contemplates isolated conduct.

See 29 U.S.C. § 203(o) (treating “custom” and “practice” as synonymous); see also Webster’s Third New International Dictionary 1780 (2002) [hereinafter “Webster’s”] (defining “practice,” inter alia, as “perform-anee or application habitually engaged [in]” and “repeated or customary action” (emphases added)). In sum, we agree that Ms. Ellis did not meet her

summary-judgment burden regarding her first argument for reversal. We reach this conclusion because, as a matter of law, Ms. Ellis’s failure to identify more than the April 3, 2012, deduction precluded a finding of an “actual practice,” 29 C.F.R. § 541.603(a), by the Company of making improper salary deductions. b Ms. Ellis’s second salary-basis argument does not give us pause in reaching this conclusion.

Specifically, she directs her fire at what she perceives to be the Company’s impermissible deductions policy and contends that “[she] raised a genuine issue of material fact concerning the existence of an employer policy requiring deduction from her pay when she was absent from work for a brief period of time.” Aplt. Opening Br. at 21. This argument implicates both subsections (

a) and (d): subsection (

a) expressly counsels courts in reaching an “actual practice” determination to inquire regarding the existence vel non of a “clearly communicated [employer] policy permitting or prohibiting improper deductions,” and subsection (d)’s provisions inform that specific inquiry. However, we agree with the district court’s determination that the Company had no “policy” requiring improper deductions. And, therefore, we do not fault the court’s explicit repudiation of Ms.

Ellis’s “assertion] that the $31.20 deduction on April 3, 2012, ... was part of a policy requiring a deduction maintained by J.R.’s.” Aplt.App. at 453 (internal quotation marks omitted). As a preliminary matter, we note that the approach taken by the DOL with respect to an employer’s “policy” regarding deductions in the context of the salary-basis test is not hypertechnical. That is, the Secretary rejects a wooden requirement of actual deductions, but in their absence ... requires a clear and particularized policy—one which effectively communicates that deductions will be made in specified circumstances.

This avoids the imposition of massive and unanticipated overtime liability ... in situations in which a vague or broadly worded policy is nominally applicable to a whole range of personnel but is not significantly likely to be invoked against salaried employees. Auer, 519 U.S. at 461, 117 S.Ct. 905 (emphasis added) (citation omitted) (internal quotation marks omitted). Relevant here, the Company’s “policy,” as set forth in the version of the employee handbook in effect during Ms.

Ellis’s employment, declares that “[t]he Company prohibits deductions from an exempt, salaried employee’s pay except under the circumstances set forth in the [FLSA] and state law. If you believe that improper [deductions have occurred], it will promptly reimburse the employee and ensure the mistake will be corrected in the future.” ApltApp. at 384 (Emp. Handbook, filed Jan. 11, 2013). We would be hard-pressed to conclude that this language evinces a policy that mandates improper deductions, as Ms. Ellis intimates on appeal. Indeed, essentially the obverse, is true.

This is so because the foregoing handbook language tracks the text of the Secretary’s guidance regarding the salary-basis test, which specifies that an employer will retain the exemption as long as it maintains “a clearly communicated policy that prohibits the improper pay deductions specified in [sub- • section] (

a) and includes a complaint mechanism, reimburses employees for any improper deductions and makes a good faith commitment to comply in the future.” 29 C.F.R. § 541.603(d). Nevertheless, in Ms. Ellis’s view, the Company’s FLSA-related handbook policy flouts the regulatory scheme for two reasons. First, she claims, “[a] policy that requires the employee to research the law to determine the employer’s policy does not clearly communicate which deductions are not allowed.” Aplt. Opening Br. at 32. We understand Ms.

Ellis to argue that the law requires employers not to task their exempt employees with “learning that deductions from an exempt employee’s pay for absences from work of less than a day’s duration are prohibited by the FLSA.” Aplt.App. at 360 (Resp. to Mot. for Summ. J., filed Jan. 11, 2013). This contention did not avail her in the district court because she failed to marshal any authority “indicating that a policy fails to be clear merely because it incorporates by reference, but does not reiterate in full, the governing law.” Id. at 454 n. 4. Nor does this contention help Ms.

Ellis here; for, like the district court did, we find her hypothesis unsupported. Given Ms. Ellis’s obligation to prove the Company violated the FLSA, we cannot conclude that she has succeeded in light of the Company handbook’s obvious discussion of deductions in the context of “the circumstances set forth in the federal Fair Labor Standards Act (FLSA) and state law.” Id. at 384.

The “best evidence of a clearly communicated policy” is one “distributed to employees ... by, for example, providing a copy of the policy to employees at the time of hire, [or] publishing the policy in an employee handbook.” 29 C.F.R. § 541.603(d). The Company clearly satisfied the criterion of adequate communication in this case by furnishing its handbook. Ms. Ellis’s second argument on this score is even more tenuous: she claims that “[the Company’s] policy did not contain a complaint mechanism” and, therefore, the Company could not retain the exemption. Aplt. Opening Br. at 32.

This contention is patently incorrect. Our review of the employee handbook makes clear that it contemplates at least three species of employee complaints. An employee who experiences or observes harassment “must promptly notify the supervisor”—or, if she believes a violation of the law has occurred, she “is directed to advise the [Company] President.” Aplt. App. at 383. If an employee suspects her pay has been reduced, because of a “cash shortage or gas skip,” she “should notify [her] supervisor or the Company President immediately.” Id. at 384. Finally—and most germane to this case—the handbook has a

section discussing “open door communications” that provides, “If you have a problem, complaint, or need help with anything related to your job, ... [y]ou may ... [t]alk to your supervisor; or ... if you are not satisfied with. the results of such a discussion, please contact the President.” Id. at 383-84 (capitalization altered) (emphases added). In light of these provisions, we reject Ms. Ellis’s bald assertion regarding the absence of a complaint mechanism and reiterate our view that the Company’s deductions policy permits it to retain the challenged exemption.

For these reasons, we hold that the district court correctly found no evidence of an “actual practice” of making improper deductions or of a “policy” of making improper deductions by the Company. Therefore, the district court properly declined Ms. Ellis’s invitation to strip the Company, under the authority of subsection (a), of its exemption as to Ms. Ellis. 3 Next, Ms. Ellis entreats us to reverse the district court based upon its purported “evasion of the spirit of the FLSA,” Aplt. Opening Br. at 19-that is, its failure to consider her employment conditions sufficiently oppressive.

She complains, “Reading the District Court’s order one could conclude that an employer can adopt a hard floor of fifty hours and assign to the employee a virtually unlimited amount of work,” id. at 15, and that such an employer could still evade the FLSA’s overtime requirements. The crux of her argument, however, is that the district court relied upon improper precedent in making its determinations. Having carefully reviewed the district court’s ruling, we reach a different conclusion. Ms. Ellis challenges the district court’s reliance upon various DOL

interpretations of the FLSA’s implementing regulations, claiming that the court impermissibly cited DOL statements and opinion letters in order to avoid addressing her allegedly “extraordinary” working conditions. Id. at 16. In lodging this argument, though, she overlooks the deference that we and other courts have shown to the DOL’s

interpretation of its own regulations. Indeed, seventy-one years ago, we held that Congress, in effect, provided that employees should be exempt who fell within certain general classifications as rationally and reasonably defined and made certain by the [DOL’s Wage and Hour] Administrator. The general standard was laid down by Congress[ ]—bona fide executive, administrative, or professional capacity. The policy was made manifest by Congress[]—that of precise definition and delimitation by a reasonable and rational regulation defining and delimiting the general terms.

The delegation of such a power to define and delimit has been sustained by the decisions of the Supreme Court[J Congress has laid down a general standard and manifest a policy and within the framework thereof has delegated to the Administrator the duty to supply the details. Walling v. Yeakley, 140 F.2d 830, 832 (10th Cir.1944) (footnote omitted). In looking to the DOL’s Wage and Hour Administrator for such interstitial particulars, we have subsequently recognized the permissibility of deferring to the DOL’s

interpretations of the FLSA scheme by way of opinion letters. See In re Wal-Mart, 395 F.3d at 1184 (“The DOL considers these opinion letters to be rulings.... [0]pinion letters are entitled to great weight when they interpret the DOL’s own (ambiguous) regulations.” (citations omitted) (internal quotation marks omitted)); see also Rodriguez v. Whiting Farms, Inc., 360 F.3d 1180, 1189 (10th Cir.2004) (“[W]e may look to such opinions for guidance. Such

interpretations are entitled to respect.” (internal quotation marks omitted)). And, in this same vein, the Supreme Court has established the propriety of seeking interpretive guidance from the DOL’s

preambles to its regulations. See Christopher v. SmithKline Beecham Corp., — U.S. -, 132 S.Ct. 2156, 2162-63, 183 L.Ed.2d 153 (2012) (interpreting the term “employee employed in the capacity of outside salesman” in an FLSA exemption by looking to the DOL’s regulations, and also finding that “[additional guidance concerning the scope of the outside salesman exemption can be gleaned from ... the

preamble to the 2004 regulations” (internal quotation marks omitted)); see also Ramos v. Baldor Specialty Foods, Inc., 687 F.3d 554, 560-61 (2d Cir.2012) (interpreting the term “a customarily recognized department or subdivision” in FLSA’s executive exemption, and looking to the

preamble to the 2004 regulation as an interpretive guidepost). In light of the foregoing authority, it is clear that the district court was entitled to consult DOL

interpretations when ruling on the potentially ambiguous concept of intent to pay a salary. In particular, the court did not err in reasonably relying on the

preamble to the regulations or a 2006 DOL opinion letter. See In re Wal-Mart, 395 F.3d at 1186 (“[W]e need not take a jaundiced view of the DOL’s own

interpretation of ‘salary.’ ”). Both agency

interpretations provide strong justification for the district court’s conclusion that Ms. Ellis’s purportedly unduly burdensome job requirements did not run afoul of the Company’s duties under the FLSA. We are not unsympathetic to the hours of diligent work Ms. Ellis provided to the Company as a store manager. Nonetheless, it is pellucid that she was aware of this requirement throughout her employment—indeed, she admits that the Company’s leadership regularly apprised store managers of the Pay Plan’s position on work hours. Critically, Ms.

Ellis has not met her burden of proving that the fifty-hour-week minimum or the directive to track her hours expressly violates the FLSA. The DOL made clear, in unveiling amended salary-basis regulations in 2004, that “employers, without affecting their employees’ exempt status, may take deductions from accrued leave accounts; may require exempt employees to record and track hours; may require exempt employees to work a specified schedule; and may implement across-the-board changes in

schedule under certain circumstances.” Defining and Delimiting the Exemptions for Executive, Administrative, Professional, Outside Sales and Computer Employees, 69 Fed.Reg. 22,122, 22,178 (Apr. 28, 2004) (emphasis added). It is difficult to harmonize that language with Ms. Ellis’s suggestion that the DOL’s

interpretation lacked the “power to persuade” the district court (or, us, for that matter). Aplt. Opening Br. at 16 (quoting Christensen v. Harris Cnty., 529 U.S. 576, 587, 120 S.Ct. 1655, 146 L.Ed.2d 621 (2000)) (internal quotation marks omitted). In our view, the district court’s choice to credit the above-cited statements of the DOL was entirely reasonable. Similarly, we are not troubled by the district court’s citation to a 2006 DOL opinion letter in its assessment.

This particular letter was issued in response to an employer’s “wish[ ] to require exempt employees to work either 45 or 50 hours a week” and “to require ... that exempt employees make up work time lost due to personal absences of less than a day.” Aplt.App. at 33 (DOL Op. Letter No. FLSA2006-6, dated Mar. 10, 2006). The employer’s concern was not whether it could effect any salary deductions for employees who violated these proposed rules, but whether “consistent failure to observe the proposed requirements [c]ould result in discipline.” Id. (internal quotation marks omitted).

The DOL opined that the employer could implement the requirements with impunity—i.e., under those hypothetical facts, the employer would not lose the exemption. More to the point, the DOL advised that [t]he number of hours worked by an employee ... is a matter to be determined between the employer and the employee. An employer may require an exempt employee to make up work time lost due to personal absences of less than a day without loss of the exemption. ... As the

preamble to the final rule explains, an employer may require an exempt employee to do things such as to record and track hours and to work a specified

schedule without affecting the employee’s exempt status. Id. (citing Cowart v. Ingalls Shipbuilding, Inc., 213 F.3d 261 (5th Cir.2000)). These principles find support in both binding and persuasive caselaw. See, e.g., Aaron, 54 F.3d at 658 (“[T]he fact that the [employees’] paystubs indicated the number of hours covered is ... not inconsistent with salaried status. Such an accounting of hours is necessary....”); see also Spradling, 95 F.3d at 1500 (noting that “the facts pertaining to [the] plaintiffs’ pay are reviewed in light of Aaron”)-, accord Guerrero v. J.W.

Hutton, Inc., 458 F.3d 830, 835-36 (8th Cir.2006); Renfro v. Ind. Mich. Power Co., 370 F.3d 512, 516 (6th Cir .2004). Having failed to advance a compelling— let alone plausible—-justification for us to discount the district court’s consultation of DOL

interpretations of the FLSA, Ms. Ellis cannot prevail on this score. This particular strand of reasoning only strengthens our view that affirmance is the correct result. 4 Ms. Ellis also argues that the district court mishandled her attempt to demonstrate, via her own affidavit, a violation of the salary-basis test. The affidavit detailed Ms. Ellis’s view that the Company maintained an impermissible policy of making improper deductions—which, if true, would support her conclusion that the salary-basis test was violated. Ms.

Ellis relied heavily on this affidavit to support the assertion that the Company could not have intended to pay her a salary when the deduction at issue was intentional and made pursuant to its policy. In granting the Company’s

summary-judgment motion, the district court noted that Ms. Ellis had “supported] her assertion only with [this] affidavit which, in turn, merely recitefd] alleged statements of another [Company] manager that arguably substantiate^] Ellis’s description of [a] ‘policy’ of docking salaried employees’ pay.” Aplt.App. at 453 (emphasis added). The court found Ms. Ellis’s affidavit conclusory and self-serving. And we conclude that it was entitled to do so. As a threshold matter, Ms. Ellis is mistaken in her view that “the Court reviews this issue de novo.” Aplt. Opening Br. at 32. It is well-settled that a district court’s assessments of the admissibility and probative value of affidavits at the

summary-judgment phase involve, at bottom, evidentiary determinations; as such, they are reviewed for an abuse of discretion. See Sports Racing Servs., Inc. v. Sports Car Club of Am., Inc., 131 F.3d 874, 894 (10th Cir.1997) (“Like other evidentia-ry rulings, we review a district court’s decision to exclude evidence at the

summary judgment stage for abuse of discretion .... We cannot say that the district court abused its discretion in finding [the plaintiffs] affidavit a sham and excluding it.” (citations omitted)); accord Mitchael v. Intracorp, Inc., 179 F.3d 847, 854-55 (10th Cir.1999). Affidavits must contain certain indicia of reliability. “Unsubstantiated allegations carry no probative weight in

summary judgment proceedings^ they] must be based on more than mere speculation, conjecture, or surmise.” Bones v. Honeywell Int'l, Inc., 366 F.3d 869, 875 (10th Cir.2004) (citation omitted). Information presented in the nonmovant’s affidavit must be “based on personal knowledge and [must set] forth facts that would be admissible in evidence. We do not consider conclusory and self-serving affidavits.” Garrett v. Hewlett-Packard Co., 305 F.3d 1210, 1213 (10th Cir.2002) (citation omitted) (quoting Murray v. City of Sapulpa, 45 F.3d 1417, 1422 (10th Cir.1995)) (internal quotation marks omitted).

Because the statements in Ms. Ellis’s affidavit constitute inadmissible hearsay, they do not pass muster. In her affidavit, Ms. Ellis alleged that when she presented her time sheet for the week of her relevant absence (reflecting 40.91 hours worked), the Company’s payroll clerk asked whether she “wanted to take sick pay or vacation.” Aplt.App. at 371. Ms. Ellis claimed that she replied, “[D]o whatever you need to do.” Id. (internal quotation marks omitted).

She then described the following alleged conversation she had with the Company’s office manager after she realized she did not receive her full salary: I asked Kathy “Do we have an HR Department?” She said that would be her or Dan. I explained that I had lost a vacation day because I was sick. I was upset and asked whether that was what I got for all the 60 and 70 hour[ ] weeks I worked.... She said that is their “policy” and that is what she had to do. She said “I can get that straightened out. [The payroll clerk] should have done sick pay.”. Id. Additionally, Ms.

Ellis claimed that other Company leaders “were extremely upset that [she] had questioned the policy.” Id. She now challenges the district court’s conclusion that these particular statements would be inadmissible at trial. Basic hearsay jurisprudence makes clear that Ms. Ellis could not have introduced these statements at trial: she offered statements pertaining to her conversation with the office manager in order “to prove the truth of the matter asserted in the statement^].” Fed.R.Evid. 801(c)(2). Indeed, as Ms.

Ellis notes in her opening brief, she presented the alleged statement “[s]he said that is their ‘policy’ and that is what she had to do,” Aplt.App. at 371, in order to prove that “[the Company’s] policy required salaried employees to use a full vacation day or a full sick day when they did not work fifty hours,” Aplt. Opening Br. at 23. Stated otherwise, Ms. Ellis offered the manager’s alleged assertion that the Company had a policy—that would be legally impermissible—to prove that the Company in fad'had such a policy. This is classic hearsay; it consequently “cannot support [Ms. Ellis’s] opposition to

summary judgment.” Llewellyn v. Allstate Home Loans, Inc., 711 F.3d 1173, 1180 (10th Cir.2013); see Jaramillo v. Colo. Judicial Dep’t, 427 F.3d 1303, 1314 (10th Cir.2005) (“Hearsay testimony that would not be admissible at trial is not sufficient to defeat a motion for

summary judgment.”). Nevertheless, Ms. Ellis contends that the office manager’s statements are outside the ambit of Federal Rule of Evidence 802 because they are defined by the federal rules as non-hearsay. See Fed. R.Evid. 801(d). She urges us to consider those statements admissions of a party opponent under Rule 801(d)(2)(D).

But that would be error; “[u]nder our controlling precedent, an employee’s statements are not attributable to her employer as a party-opponent admission in an employment dispute unless the employee was ‘involved in the decisionmaking process affecting the employment action’ at issue.” Johnson v. Weld Cnty., 594 F.3d 1202, 1208-09 (10th Cir.2010) (quoting Jaramillo, 427 F.3d at 1314). Ms. Ellis’s contention that “[t]he office manager spoke as [the Company’s] representative on the subject of the pay deduction,” Aplt. Opening Br. at 23, finds no support in the record.

And reciting the office manager’s alleged statement that the Company’s human resources department “would be her,” Aplt.App. at 371, to prove that the office manager was involved in “the employment action at issue,” Johnson, 594 F.3d at 1209 (internal quotation marks omitted), is precisely what the hearsay rule forbids. Nor is this problem cured by Ms. Ellis’s assertion that “[the Company] ... does not offer any evidence” in rebuttal. Aplt. Reply Br. at 12. The Company had no need to do so, as the record is silent on the office manager’s involvement in the decisionmaking process for Ms.

Ellis’s pay deduction—except for the inadmissible “evidence” offered in Ms. Ellis’s affidavit. Ms. Ellis’s remaining argument regarding her affidavit—that we should reject the “more stringent standard” of Johnson and Jaramillo, Aplt. Reply Br. at 12—is also unconvincing. ' In her view, the better case upon which to rely is Aliotta v. National Railroad Passenger Corp., 315 F.3d 756 (7th Cir.2003). She seizes upon the Seventh Circuit’s description there of “general employment cases,” Aplt.

Reply Br. at 12, as “[having] law ... [that] is somewhat muddled because the great bulk of cases interpreting what is within an employee’s ‘scope of employment’ deals with employment discrimination.” Aliotta, 315 F.3d at 761-62. This hardly seems relevant, because even if Aliotta were an overtime-pay lawsuit (which it was not), or binding upon us (which it is not), the court in that case clearly determined that “the subject matter of the admission [must] match the subject matter of the employee’s job description.” Id. at 762. With no record evidence detailing the office manager’s job description other than Ms.

Ellis’s inadmissible hearsay statements, we could not make a similar matching determination here. We likewise agree in material respects with the district court’s resolution of Ms. Ellis’s arguments regarding the remaining affidavit statements—i.é., her averments that she worked more than her time sheets indicated. More specifically, we conclude that the district court’s reasoning was on target insofar as it found that Ms. Ellis’s unsupported assertions were at best “eon-clusory,” Aplt.App. at 454, and consequently of marginal probative value. See, e.g., Bones, 366 F.3d at 875.

Indeed, a huge dollop of conjecture would be necessary to divine from these averments a genuine issue of material fact. Cf. Aplt.App. at 373 (generally stating that “[The Company] has submitted documents ... as evidence that I didn’t work 50 hours or more during [a certain time period]. I did work more than 50 hours during [that time period]. I know I did.... ”). Perhaps, as the district court noted, Ms. Ellis could have improved her cause by submitting affidavits of other managers or co-workers. Her choice not to do so sounds the death knell for this argument.

For all of the reasons detailed above, we affirm the judgment of the district court insofar as it based its grant of

summary judgment on a finding that the Company did not violate the salary-basis test, as explicated in subsection (

a) and informed by subsection (d). We conclude that the Company intended to pay Ms. Ellis a salary, which means that she is exempt and may not receive overtime pay under the FLSA. B Next, Ms. Ellis insists that the district court’s ruling cannot stand because its

interpretation of the window-of-correction defense explicated in subsection (c) “conflicts with the principles of statutory

interpretation and the narrow

interpretation of FLSA exemptions.” Aplt. Opening Br. at 29. We disagree and hold that the district court did not err in. concluding that the Company was entitled to rely on this defense. Subsection (

c) provides that “[i]mproper deductions that are either isolated or inadvertent will not result in loss of the exemption for any employees subject to such improper deductions, if the employer reimburses the employees for such improper deductions.” 29 C.F.R. § 541.603(c) (emphases added). Here, three key facts prompted the district court to rely upon this provision. First, Ms. Ellis identified one improper paycheck deduction—$31.20 taken on April 3, 2012. Second, the Company reimbursed Ms. Ellis in the amount of $332.88 shortly after making that improper deduction. Third, Ms.

Ellis never disputed that this was an isolated deduction or that she was reimbursed in a timely manner. Consequently, given these undisputed facts, and with an eye on the “either ..'. or” language of subsection (c), the district court reasoned that “Ellis’s argument is untethered to the language of the exception.... To the extent Ellis means to equate ‘unintentional’ with ‘inadvertent,’ ... the defense can equally be satisfied when deductions are ‘isolated.’ ” ApltApp. at 459 (citation omitted). Resisting this conclusion, Ms. Ellis argues that subsection (

c) should not be “read in isolation from the remainder of the regulation,” Aplt. Opening Br. at 30, but instead, if read in context with subsections (

a) and (d), “should ... apply only when there is no other evidence of the employer’s intent, such as a policy allowing deductions,” id. at 31. Otherwise, she claims, subsections (

a) and (

d) would be nullified because an employer would have no need for a clear policy prohibiting improper deductions; instead, it could “intentionally dock an exempt employee’s pay and avoid all liability for overtime simply by reimbursing the employee.” Id. In effect, she argues that subsection (

c) is only triggered where the improper deduction is both isolated and unintentional. We cannot accept Ms. Ellis’s statutory-construction argument. Beginning with the text of subsection (c), as we must, see United States v.

Lamirand, 669 F.3d 1091, 1094 (10th Cir.2012), it is apparent that this language renders the window-of-eor-rection defense available to an employer who has made “[i]mproper deductions that are either isolated or inadvertent,” but has “reimburse[d] the employees for such improper deductions.” 29 C.F.R. § 541.603(c) (emphasis added). “[G]iven the clarity of that provision’s language, [we] could end [our analysis] there as well.” Tapia v. United States, — U.S. -, 131 S.Ct. 2382, 2388, 180 L.Ed.2d 357 (2011). We find subsection (

c) particularly clear insofar as it employs disjunctive terminology. The word “either” may be “used as a function word before two or more coordinate words ... joined usu[ally] by or to indicate that ... two or more alternatives ... are equally applicable.” Webster’s, supra, at 728. Its partner, “or,” is a “choice between alternative things.” Id. at 1585. Thus, it is patent that the district court could choose between “isolated” and “inadvertent” deductions and that both alternatives could satisfy the statute.

The court’s conclusion that “[t]he one-time deduction ... was certainly ‘isolated,’ ” ApltApp. at 458-59, means that it chose the “isolated” alternative as the way the Company prevailed on the window-of-correction defense. This was proper, for “isolated” means “solitary” or “occurring alone or once.” Webster’s, supra, at 1199 (capitalization omitted). The district court thus did not err in concluding that the lone improper deduction affecting Ms.

Ellis was “isolated”— even without addressing whether that improper deduction was also “inadvertent.” Generally speaking, we understand statutes containing disjunctive language to require that only one of the listed requirements must be satisfied. See, e.g., Graham v. Hartford Life & Accident Ins. Co., 589 F.3d 1345, 1353 (10th Cir.2009) (finding that a definition stating that “a plan need only be established or maintained” would be met if the party either established the plan or maintained the plan (internal quotation marks omitted)).

Additionally, we have said that “effect must be given, if possible, to every word, clause and sentence of a statute ... [which means we] therefore cannot ignore the use of the ‘or’ in” a statute and its accompanying regulations. Knutzen v. Eben Ezer Lutheran Hous. Ctr., 815 F.2d 1343, 1348-49 (10th Cir.1987) (citation omitted) (quoting 2A N. Singer, Sutherland on Statutory Construction § 46.06, at 104 (4th ed.1984)) (internal quotation marks omitted). Ms. Ellis correctly observes that courts should consider statutory and regulatory text as a whole, see Bethesda Hosp. Ass’n v.

Bowen, 485 U.S. 399, 405, 108 S.Ct. 1255, 99 L.Ed.2d 460 (1988), but she does not do so herself. Notably, her argument would contravene another subpart of the regulation—29 C.F.R. § 541.603(e)—which states, “This

section shall not be construed in an unduly technical manner so as to defeat the exemption.” Cf. First Nat’l Bank of Durango v. Woods (In re Woods), 743 F.3d 689, 702 (10th Cir.2014) (discouraging

interpretation that would effectively mean “that the exception would almost never apply” and concluding that Congress could not have intended such a “limiting effect” that “would almost entirely eviscerate the exception”). In that regard, a leading authority on statutory construction instructs us that: [i]t is not a proper use of the [“whole-text”] canon to say that since the overall purpose of the statute is to achieve x, any

interpretation of the text that limits the achieving of x must be disfavored. ... [L]imitations on a statute’s reach are as much a part of the statutory purpose as specifications of what is to be done. Antonin Scalia & Bryan A. Garner, Reading Law: The

Interpretation of Legal Texts 168 (2012). This concept is particularly apt here because Ms. Ellis repeatedly argues that the FLSA is a remedial statute designed to be resolved “in favor of employee coverage.” Aplt. Opening Br. at 14; accord id. at 15; id. at 19; id. at 43. The fact that one purpose of the FLSA is to ensure overtime pay for non-exempt employees does not preclude the possibility that an employer may “intentionally dock an exempt employee’s pay and avoid all liability for overtime simply by reimbursing the employee.” Id. at 31.

Such a situation does not necessarily abuse the window-of-correction defense or eviscerate the employee’s exempt status—provided, of course, that the intentional (i.e., not inadvertent) deduction was “isolated.” While we note that some of our sister circuits have intimated that this defense can only apply when an employer has made an innocent mistake, we remind Ms. Ellis that these decisions are not binding upon us.

Our own precedent makes clear that “[t]he ‘window of correction’ provided by [the predecessor version of subsection (c) ] allows employers to treat otherwise eligible employees as salaried, regardless of the employer’s one-time or unintentional failure to adhere to” the statute’s prohibition on improperly deducting salaried employees’ pay based on quantity of work performed. Spradling, 95 F.3d at 1503 (emphasis added).

And our holding in Spradling leads ineluctably to the conclusion that the district court properly allowed the Company to rely upon the window-of-correction defense regarding its lone improper deduction to Ms. Ellis’s pay. C In conclusion, we hold that subsections (

a) and (

c) can be read harmoniously. We further hold that the Company can rely on both provisions here: as to the former, there was no practice or policy of making inappropriate pay deductions for salaried employees; and, as to the latter, the one time the Company acted improperly as regards Ms. Ellis, that action was isolated. On these grounds, we affirm. IV Finally, we address the district court’s denial of Ms. Ellis’s motion to defer

summary judgment for the gathering of additional discovery under Federal Rule of Civil Procedure 56(d). In doing so, we are mindful of the Supreme' Court’s directive that “summary judgment [should] be refused where the nonmoving party has not had the opportunity to discover information that is essential to his opposition.” Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 250 n. 5, 106 S.Ct. 2505, 91 L.Ed.2d 202 (1986). We likewise note our obligation, under the abuse-of-discretion rubric, to “defer to the district court’s judgment so long as it falls within the realm of [the] rationally available choices.” Shook v.

Bd. ofCnty. Comm’rs, 543 F.3d 597, 603 (10th Cir.2008) (internal quotation marks omitted); accord Barber ex rel. Barber v. Cob. Dep’t of Revenue, 562 F.3d 1222, 1228 (10th Cir.2009). Here, as we explain below, we lack any cogent basis to disturb the reasoned judgment of the district court, and we conclude that it properly applied the governing rule. Rule 56(

d) allows the nonmovant to “show[] by affidavit or declaration that, for specified reasons, [she] cannot present facts essential to justify ... opposition [to a motion for

summary judgment].” Fed. R.Civ.P. 56(d). The district court may then: “(1) defer considering the motion or deny it; (2) allow time to obtain affidavits or declarations or to take discovery; or (3) issue any other appropriate order.” Id.; accord Arciero, 741 F.3d at 1116. The party seeking to enlarge the discovery period under this rule “must present an affidavit that identifies ‘the probable facts not available and what steps have been taken to obtain these facts.

The [party] must also explain how additional time will enable [her] to rebut the movant’s allegations of no genuine issue of material fact.’ ” Arciero, 741 F.3d at 1116 (quoting Trask v. Franco, 446 F.3d 1036, 1042 (10th Cir. 2006)); see also Been v. O.K. Indus., Inc., 495 F.3d 1217, 1235 (10th Cir.2007) (“[A] party at a minimum must ask the court to refrain from acting on the

summary judgment request until additional discovery can be conducted.” (internal quotation marks omitted)). We expect Rule 56(

d) motions to be robust, and we have observed that “[an] affidavit’s lack of specificity” counsels against a finding that the district court abused its discretion in denying a request for additional discovery under the rule. Trask, 446 F.3d at 1042. Ms. Ellis attempted to satisfy the foregoing directives in the district court by submitting the affidavit of Attorney Bradley Sherman. According to that affidavit, the probable facts unavailable to Ms.

Ellis included information in “pay records, deposition testimony, and other documents” that would “show a wide ranging policy and practice of making improper deductions” and allow Ms. Ellis “to determine if any deductions were in fact ‘isolated’ or not.” Aplt.App. at 319 (Aff. of Bradley Sherman, dated Oct. 31, 2012). The affidavit further indicated that Ms. Ellis had participated in the discovery conference required by Federal Rule of Civil Procedure 26(f), which we construe as an averment that Ms. Ellis had taken a step to obtain the allegedly unavailable facts.

Finally, the affidavit explained that additional time was essential to the litigation not only because of its early procedural posture (i.e., that Ms. Ellis simply had not had adequate time to investigate these facts), but also because, in Ms. Ellis’s view, “the analysis under 29 C.F.R. § 541.603 extends beyond a single employee and instead encompasses the employer’s pay practices regarding a broad range of employees.” Id. at 320. But the district court was not persuaded that such a wide swath of discovery was necessary.

In fact, it found that Attorney Sherman’s affidavit failed to demonstrate the need for any further discovery beyond Ms. Ellis’s pay and time records. Reasoning that this affidavit only raised a speculative hope of unearthing evidence sufficient to prevail at

summary judgment, the court denied Ms. Ellis’s motion. We are satisfied—notwithstanding Ms. Ellis’s arguments on appeal—that this ruling involved no abuse of discretion. We first address Ms. Ellis’s argument that she was unable to rebut the Company’s “isolated-deduction” allegations without a thorough “analysis of [the Company’s] pay practices regarding other employees.” Id. at 318. Ms. Ellis apparently believes that subsection (

a) always contemplates an employer-wide assessment—and, to be sure, subsection (

a) lists among its nonexhaustive factors “the number and geographic location of employees whose salary was improperly reduced.” 29 C.F.R. § 541.603(a). However, the inclusion of that particular factor among many does not render it mandatory. Thus, the district court was not legally required under all circumstances to consider any improper deductions involving other employees. And, on these facts, it did not abuse its discretion in declining to grant Ms. Ellis additional time to conduct discovery relating to any improper deductions made from other employees’ salaries. In this regard, we note that, at the precise moment the Company filed its motion for

summary judgment, the scope of the lawsuit was explicitly limited to one named plaintiff: Ms. Ellis. This remained true throughout all proceedings germane to this appeal, as evidenced by the district court’s contemporaneous rulings on the Company’s

summary-judgment motion (which it granted) and Ms. Ellis’s class-certification motion (which it denied). Thus, the district court did not commit legal error or otherwise abuse its discretion in declining to allow additional time to conduct other-employee discovery. Next—and relatedly—we reject Ms. Ellis’s contention that the procedural posture of her case justified relief under Rule 56(d). More to the point, one of the reasons she filed a Rule 56(

d) motion was that she was convinced that the Company’s then-pending

summary-judgment motion was directly aimed at thwarting an anticipated class action. The timeline of this litigation does not conclusively foreclose the possibility that the Company actually was motivated in this manner, but it does cast substantial doubt on the notion: the Company moved for

summary judgment on October 11, 2012; Ms. Ellis moved to certify a class on October 18, 2012; and Ms. Ellis moved for relief under Rule 56(

d) on October 31, 2012. Specifically, the problem for Ms. Ellis is her failure to attach any legal significance to the fact that the Company’s motion for

summary judgment predates her motion for class certification—viz., she has presented no convincing argument that the district court was somehow constrained to rule on the class-certification motion before the

summary-judgment motion. We submit that she cannot make this showing because no such obligation existed. See Crowley v. Montgomery Ward & Co., 570 F.2d 877, 879 (10th Cir.1978) (affirming the district court’s decision to dispose of case on

summary judgment even though “no ruling was made on the certification of the class”); cf. 7AA Charles Alan Wright et al., Federal Practice and Procedure § 1785.3, at 457 (3d ed. 2005) (“[I]t generally seems agreed that certification at the judgment stage is not automatically prohibited.”). Consequently, given the generous nature of the abuse-of-discretion standard, this argument lends Ms. Ellis no succor. On this record, we would be hard-pressed to find fault with the district court’s conclusion that Ms. Ellis required no further discovery to respond to the Company’s

summary-judgment motion. By that point in the case, the Company had provided time sheets and pay records for the relevant time period set forth in Ms. Ellis’s complaint, which was all Ms. Ellis could reasonably have required to rebut the Company’s allegations as they related to her, the sole named plaintiff. Those materials unmistakably revealed that the Company made only one deduction to Ms. Ellis’s pay in the amount of $31.20—a fact Ms. Ellis has never disputed. Moreover, while the

summary-judgment and class-certification motions were pending, the Company amended its answers to Ms. Ellis’s interrogatories to reflect that it had previously made pay deductions for two other store managers. This amendment did not benefit Ms. Ellis, though, because both cited subtractions stemmed from the employees’ use of “a full sick day,” Aplt.App. at 423 (Resp. to Pl.’s Mot. to Supplement R., Ex. A, filed Feb. 22, 2013), which is permissible under 29 C.F.R. § 541.602(b)(2). In light of Ms. Ellis’s obvious failure to marshal evidence of improper deductions, as the FLSA regulations contemplate, it was hardly irrational for the district court to have found her Rule 56(

d) motion speculative. We have held that a litigant’s unsupported averments cannot justify deferring a ruling on—let alone denying altogether—a motion for

summary judgment. See Meyer v. Dans un Jardin, S.A., 816 F.2d 533, 537 (10th Cir.1987) (“The nonmoving party has the burden of showing ... how additional time will enable [her] to rebut the movant’s allegations.” (emphasis added)); accord Culver v. Town of Torrington, 930 F.2d 1456, 1458-59 (10th Cir.1991). And, in a similar procedural context in Lewis v. City of Ft. Collins, we reached a result that further undermines Ms. Ellis’s position: In her brief in response to the motion for

summary judgment, plaintiff asserts that there has been “insufficient time for discovery” and that “[t]he parties have not begun the discovery process.” Thus, plaintiff argued that appellants’ motion for

summary judgment was “premature” and “improper.” Within the affidavit itself, plaintiff repeatedly asserts that she “will be able to show” certain facts relative to her claims.... These inspecific references are simply insufficient to meet [Rule 56(d) ] muster. ... Plaintiff has not attempted to particularize her request for discovery. She has not explained how any specific documents or depositions will aid in rebutting defendants’ showing of objective reasonableness. [Rule 56(d) ] is not a license for a fishing expedition.... 903 F.2d 752, 758-59 (10th Cir.1990) (first alteration in original) (emphasis added). Guided by these cases, we believe denying Ms. Ellis’s Rule 56(

d) motion was entirely appropriate. Reduced to its essence, then, Ms. Ellis’s Rule 56(

d) challenge on appeal comprises her view that because the district court could have granted the motion, it should have done so. That is patently not the law; “[u]nder an abuse of discretion standard, a trial court’s decision will not be disturbed unless the appellate court has a definite and firm conviction that the lower court made a clear error of judgment or ■exceeded the bounds of permissible choice in the circumstances.” Wright ex rel. Trust Co. of Kan. v. Abbott Labs., Inc., 259 F.3d 1226, 1235 (10th Cir.2001) (internal quotation marks omitted). No such error or impermissible choice is evident from this record. Accordingly, we affirm the district court’s denial of Ms. Ellis’s Rule 56(

d) motion. V For the reasons explicated above, we AFFIRM. . "Because the salary-basis test is a creature of the Secretary’s own regulations, his

interpretation of it is ... controlling unless plainly erroneous or inconsistent with the regulation.” Auer, 519 U.S. at 461, 117 S.Ct. 905 (internal quotation marks omitted). . The Company submitted time sheets indicating that for certain isolated weeks during her employment, Ms. Ellis reported working fewer than fifty hours. . As the district court observed, the "parties maintain different, though overlapping, explanations as to why Ellis’s pay was reduced.” Aplt.App. at 448 n. 1 (Order Granting Mot. for ■ Summ. J., filed July 12, 2013). Compare id. at 27 n. 3 (Mot. for Summ.

J., hied Oct. 11, 2012) ("Plaintiff ... informed J.R.’s that she wanted to use a sick day instead of a vacation day.”), with id. at 371 (Aff. of Sandra Ellis, dated Jan. 9, 2013) ("I ... lost a vacation day because I was sick.”). For our purposes, the principal points are (1) that Ms. Ellis failed to work the mandatory fifty-hour business week during that pay period, and (2) that "the parties agree that Ellis’s pay was reduced as a result of her inability to” do so. Id. at 448 n. 1. . For example, Ms. Ellis contends that if the Company is stripped of its exemption under subsection (

a) by virtue of a practice or policy of making improper deductions, then, as a matter of law, such conduct cannot be "isolated” under subsection (c). If we were obliged to reach this issue, we certainly would consider Ms. Ellis's position worthy of serious consideration and would not be inclined to summarily reject it out of hand. However, because the two provisions harmonize for purposes of this appeal, we need not venture down this road. . While we would not describe the Pay Plan as one “unlike any other,” Aplt. Opening Br. at 20, we note that existing caselaw at least suggests that the Pay Plan is unusual.

But the few isolated cases we have located—involving compensation plans that obligate employees to work in the vicinity of fifty hours per week—are not favorable to Ms. Ellis’s position. For instance, in an unpublished opinion, a panel of the Third Circuit considered the salaiy-basis test fulfilled when, under the operative plan, "[the plaintiff] was entitled to a guaranteed base pay of $60,000, and she was expected to work 45 hours per week.” Sander v. Light Action, Inc., 525 Fed.Appx. 147, 148 (3d Cir.2013). Some district courts have likewise found the test satisfied on similar facts. See, e.g., Ottaviano v.

Home Depot, Inc., 701 F.Supp.2d 1005, 1008-09 (N.D.Ill. 2010) (deeming employees exempt when Home Depot required a fifty-five-hour work week); Clougher v. Home Depot U.S.A., Inc., 696 F.Supp.2d 285, 295 (E.D.N.Y.2010) (finding that "the mere fact that Home Depot required even its salaried employees to work no less than 55-hours per week or face discipline ... [did] not undermine [the plaintiff’s] proper classification as a salaried employee"); Palazzolo-Robinson v. Sharis Mgmt.

Corp., 68 F.Supp.2d 1186, 1192 (W.D.Wash.1999) (finding an employee who "was told [when hired] ... that all managers worked 50 hours a week, ... and that compensation would be on a salary basis” to be exempt (internal quotation marks omitted)). Other cases involving mandatory "forty-hour-plus” work weeks also lend Ms. Ellis no succor because they arise in the context of the "fluctuating” work week, described at 29 C.F.R. § 778.114, which is inapposite here. Ultimately, under our controlling precedent, we cannot agree that the terms of the Pay Plan militate in favor of considering Ms.

Ellis non-exempt and stripping the Company of its exemption under subsection (a). . The, Court relied on a leading treatise on statutory construction which provides that, '‘[o]rdinarily[,] the legislature by use of a plural term intends a reference to more than one matter or thing,” 2A N. Singer, Sutherland on Statutory Construction § 47.34, at 274 (5th ed.1992), in reaching this conclusion. See Metro. Stevedore Co., 515 U.S. at 296, 115 S.Ct. 2144. . In fact, though decided in contexts different than this one, several cases expressly discussing incorporation by reference undermine Ms. Ellis's argument.

See, e.g., Doe v. Harris, 535 Fed.Appx. 630, 631 (9th Cir.2013) (declaring that California's "general rule” is that plea agreements "will be deemed to incorporate ... the existing law” (internal quotation marks omitted)), cert. denied, - U.S. -, 134 S.Ct. 1945, 188 L.Ed.2d 961 (2014); Fortier v. Principal Life Ins. Co., 666 F.3d 231, 238
