OPINION

GRABER, Circuit Judge:

We consider here a question of first impression for our circuit: Are "service advisors" who work at a car dealership exempt from the overtime pay requirements of the Fair Labor Standards Act (FLSA) of 1938, 29 U.S.C. §§ 201-219, under 29 U.S.C. § 213(b)(10)(A), which exempts "any salesman, partsman, or mechanic primarily engaged in selling or servicing automobiles"? Reviewing de novo, Fortyune v. City of Lomita, 766 F.3d 1098, 1101 (9th Cir.2014), petition for cert. filed, ___ U.S.L.W. ___ (U.S. Jan. 26, 2015) (No. 14-920), we answer that question "no" and, accordingly, reverse the district court's holding to the contrary.

FACTUAL AND PROCEDURAL HISTORY

Defendant Encino Motorcars, LLC, sells and services new and used Mercedes-Benz automobiles.1 Defendant employed or employs Plaintiffs Hector Navarro, Mike Shirinian, Anthony Pinkins, Kevin Malone, and Reuben Castro as "service advisors." The complaint alleges:

Defendant pays service advisors on a commission basis only; Plaintiffs receive neither an hourly wage nor a salary.

In 2012, Plaintiffs filed this action alleging, among other things, that Defendant has violated the FLSA by failing to pay overtime wages. The district court dismissed the overtime claim because, the court concluded, Plaintiffs fall within the FLSA's exemption for "any salesman, partsman, or mechanic primarily engaged in selling or servicing automobiles." 29 U.S.C. § 213(b)(10)(A). Plaintiffs timely appeal.2

DISCUSSION

Title 29 U.S.C. § 207(a)(1) requires that employers pay time-and-a-half for hours worked in excess of 40 per workweek. But § 213(b)(10)(A) provides that "[t]he provisions of section 207 of this title shall not apply with respect to ... any salesman, partsman, or mechanic primarily engaged in selling or servicing automobiles, trucks, or farm implements, if he is employed by a nonmanufacturing establishment primarily engaged in the business of selling such vehicles or implements to ultimate purchasers." Defendant, as a car dealership, is a "nonmanufacturing establishment primarily engaged in the business of selling ... vehicles ... to ultimate purchasers." Id. The question is whether each Plaintiff is a "salesman, partsman, or mechanic primarily engaged in selling or servicing automobiles." Id.

Plaintiffs argue that we must defer to the United States Department of Labor's 2011 regulatory definitions, set out at 29 C.F.R. § 779.372(c). 76 Fed.Reg. 18,832-01 (Apr. 5, 2011). Those regulations state, in relevant part:

Salesman, partsman, or mechanic.

29 C.F.R. § 779.372(c). As the agency explained in 2011, the regulatory definitions "limit[] the exemption to salesmen who sell vehicles and partsmen and mechanics who service vehicles." 76 Fed. Reg. at 18,838. Because Plaintiffs do not fit within any of those definitions, they are not exempt from the FLSA's overtime wage provisions. Defendant concedes that Plaintiffs do not meet the regulatory definitions, but counters that we should not defer to the regulation.

We conduct the familiar two-step inquiry to determine whether to defer to the agency's interpretation. McMaster v. United States, 731 F.3d 881, 889 (9th Cir. 2013), cert. denied, ___ U.S. ___, 135 S.Ct. 160, 190 L.Ed.2d 49 (2014). "At step one, we ask `whether Congress has directly spoken to the precise question at issue.'" Id. (quoting Chevron, U.S.A., Inc. v. Natural Res. Def. Council, Inc., 467 U.S. 837, 842, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984)). If so, then the inquiry is over, and we must give effect to the "unambiguously expressed intent of Congress." Chevron, 467 U.S. at 843, 104 S.Ct. 2778. But if the statute is silent or ambiguous, then we must determine, before step two, what level of deference applies. McMaster, 731 F.3d at 889. "If we determine that Chevron deference applies, then we move to step two, where we will defer to the agency's interpretation if it is `based on a permissible construction of the statute.'" Id. (quoting Chevron, 467 U.S. at 843, 104 S.Ct. 2778).

A. At Chevron Step One, the Statute is Ambiguous.

When construing a congressional enactment, "our inquiry begins with the statutory text." BedRoc Ltd. v. United States, 541 U.S. 176, 183, 124 S.Ct. 1587, 158 L.Ed.2d 338 (2004). In addition, in the present context we must apply the background rule that "[t]he FLSA is to be construed liberally in favor of employees; exemptions are narrowly construed against employers." Haro v. City of Los Angeles, 745 F.3d 1249, 1256 (9th Cir.), cert. denied, ___ U.S. ___, 135 S.Ct. 138, 190 L.Ed.2d 45 (2014). "FLSA exemptions... are to be withheld except as to persons plainly and unmistakably within their terms and spirit."3 Solis v. Washington, 656 F.3d 1079, 1083 (9th Cir.2011) (internal quotation marks omitted). "An employer who claims an exemption from the FLSA bears the burden of demonstrating that such an exemption applies." Id. (internal quotation marks omitted).

As noted, the statute exempts "any salesman, partsman, or mechanic primarily engaged in selling or servicing automobiles." 29 U.S.C. § 213(b)(10)(A). The statute does not define the terms "salesman, partsman, or mechanic." Examining the statutory text and applying canons of statutory interpretation, we cannot conclude that service advisors such as Plaintiffs are "persons plainly and unmistakably within [the FLSA's] terms and spirit," Solis, 656 F.3d at 1083 (internal quotation marks omitted).

It is plausible to read the term "salesman" broadly and to connect the term to "servicing automobiles"; that is, one could consider a service advisor to be a "salesman... primarily engaged in ... servicing automobiles." But, as explained in more detail below, in Part C, it is at least as plausible to read the nouns in a more cabined way: a salesman is an employee who sells cars; a partsman is an employee who requisitions, stocks, and dispenses parts; and a mechanic is an employee who performs mechanical work on cars. Service advisors do none of those things; they sell services for cars. They do not sell cars; they do not stock parts; and they do not perform mechanical work on cars.

It is not clear from the text of the statute whether Congress intended broadly to exempt any salesman who is involved in the servicing of cars or, more narrowly, only those salesmen who are selling the cars themselves. Certainly Congress did not exempt all employees of a car dealership; for example, a bookkeeper who tracks invoices for car sales and servicing is plainly not exempt, nor is a secretarial employee who routes calls to the salesmen, partsmen, and mechanics. Nor do canons of statutory interpretation aid Defendant. To the contrary, the § 213 "exemptions are narrowly construed against employers." Haro, 745 F.3d at 1256.

In sum, the statutory text and canons of statutory interpretation yield no clear answer to whether Congress intended to include service advisors within the exemption. Because Congress has not "directly spoken to the precise question at issue," Chevron, 467 U.S. at 842, 104 S.Ct. 2778, the statute is ambiguous.

B. Chevron Provides the Appropriate Lens.

When a statute is ambiguous, then we must determine, "prior to step two," the appropriate standard: either the Chevron test of reasonableness or a lower standard under United States v. Mead Corp., 533 U.S. 218, 121 S.Ct. 2164, 150 L.Ed.2d 292 (2001). McMaster, 731 F.3d at 889. Because we consider here a regulation duly promulgated after a notice-and-comment period, Chevron's "reasonableness" standard applies. See, e.g., Renee v. Duncan, 623 F.3d 787, 795 (9th Cir.2010) ("The challenged federal regulation interprets a federal statute. The regulation was adopted by the responsible federal agency through notice and comment rulemaking. We therefore apply the analytical framework outlined in Chevron.").

Nothing in the history of the regulation undermines that conclusion. Indeed, the original version of the regulation, promulgated in 1970, contained the same narrow definitions of "salesman," "partsman," and "mechanic." See 29 C.F.R. § 779.372(c)(1)-(3) (1970); see also Dep't of Lab., Wage & Hour Div., Opinion Letter No. 660, 66-69 Lab. Cas. (CCH) ¶ 30,652 (Aug. 4, 1967) (also providing the same narrow definitions). Those regulatory definitions have not changed in any relevant way since 1970. Because the agency's formal, regulatory position has not changed, the cases cited by Defendant are not on point. In Christopher v. SmithKline Beecham Corp., ___ U.S. ___, 132 S.Ct. 2156, 2165, 183 L.Ed.2d 153 (2012), the Supreme Court addressed what level of deference to give to an agency's interpretation of its own regulations. Importantly, the parties agreed that "the regulations themselves... [were] entitled to deference under Chevron." Id. Similarly, Sandifer v. U.S. Steel, 678 F.3d 590, 598-99 (7th Cir.2012), involved only opinion letters; the agency had not issued formal regulations.

It is true that the Department of Labor occasionally has adopted the broader definitions, urged by Defendant here, in documents other than regulations. For example, the agency issued an opinion letter in 1978 that defined a "salesman" to encompass service advisors. Dep't of Lab. Opinion Letter No. WH-467, 1978 WL 51403 (July 28, 1978). Similarly, the agency amended its Field Operations Handbook in 1987 along the same lines. Field Operations Handbook, Dep't of Lab., Wage & Hour Div., 24L04-4, Insert No. 1757 (Oct. 20, 1987).

The agency even proposed amending the formal regulation to adopt the broader definitions. 73 Fed.Reg. 43,654-01, 43,658-59, 43,671 (July 28, 2008). But it ultimately decided against making that change after receiving comments from the public and considering the relevant court decisions. 76 Fed.Reg. at 18,838. The agency "acknowledge[d] that there are strongly held views on several of the issues presented in this rulemaking, and it has carefully considered all of the comments, analyses, and arguments made for and against the proposed changes in developing this final rule." Id. at 18,832. The regulatory history shows that the Department of Labor has given this particular issue considerable thought and has concluded that the better reading of the statute is to "limit[] the exemption to salesmen who sell vehicles and partsmen and mechanics who service vehicles." Id. at 18,838.

Moreover, even if we were to consider the agency's 2011 final rule a change of position, we still would conclude that Chevron supplies the appropriate standard of deference. As the Supreme Court explained in FCC v. Fox Television Stations, Inc., 556 U.S. 502, 129 S.Ct. 1800, 173 L.Ed.2d 738 (2009), an agency is permitted to change its position. Consistent with Fox, the agency here expressly acknowledged that its position was contrary to its earlier opinion letter, and the agency rationally explained why, in its view, the court decisions to the contrary were erroneous. Under Fox, 556 U.S. at 515-18, 129 S.Ct. 1800, nothing more is required. Cf. Perez v. Mortg. Bankers Ass'n, ___ U.S. ___, 135 S.Ct. 1199, ___ L.Ed.2d ___ (2015) (holding that an agency may change its position in an interpretive rule without notice and comment).

The Department of Labor's regulations consistently — for 45 years — have interpreted the statutory exemption to apply narrowly. The agency reaffirmed that interpretation most recently in 2011, after thorough consideration of opposing views and after a formal notice-and-comment process. Under these circumstances, Chevron provides the appropriate legal standard.

C. At Chevron Step Two, the Regulation Is Reasonable.

"Under Chevron step two, if the agency's interpretation is a reasonable one, this court may not substitute its own construction of the statutory provision." CHW W. Bay v. Thompson, 246 F.3d 1218, 1223 (9th Cir.2001) (brackets and internal quotation marks omitted). Here, the Department of Labor has interpreted the statutory exemption to exclude service advisors by choosing the narrower definition of the term "salesman." For the reasons described below, we conclude that the agency has made a permissible choice. The interpretation accords with the presumption that the § 213 exemptions should be construed narrowly. Haro, 745 F.3d at 1256. Moreover, we are mindful of our role as a reviewing court: "The agency's interpretation need not be the best construction of the ambiguous statute." Cervantes v. Holder, 772 F.3d 583, 591 (9th Cir.2014).

We recognize that our decision to uphold the agency's interpretation conflicts with decisions of the Fourth and Fifth Circuits, several district courts, and the Supreme Court of Montana. Walton v. Greenbrier Ford, Inc., 370 F.3d 446 (4th Cir.2004); Brennan v. Deel Motors, Inc., 475 F.2d 1095 (5th Cir.1973); Brennan v. N. Bros. Ford, Inc., No. 40344, 1975 WL 1074 (E.D.Mich. Apr. 17, 1975) (unpublished), aff'd sub. nom Dunlop v. N. Bros. Ford, Inc., 529 F.2d 524 (6th Cir.1976) (table); Brennan v. Import Volkswagen, Inc., No. W-4982, 1975 WL 1248 (D.Kan. Oct. 21, 1975) (unpublished); Yenney v. Cass Cnty. Motors Co., No. 76-0-294, 1977 WL 1678 (D.Neb. Feb. 8, 1977) (unpublished); Thompson v. J.C. Billion, Inc., 368 Mont. 299, 294 P.3d 397 (2013). We respectfully disagree with those decisions.

In Deel Motors and the district court opinions following that case in the 1970s, courts held that service advisors are exempt because their duties and pay structure are "functionally similar" to those of the salesmen, partsmen, and mechanics whom the statute expressly exempts. 475 F.2d at 1097. But those cases pre-dated Chevron and the modern framework for deferring to an agency's interpretation. See id. (asking not whether the agency's interpretation was reasonable but, instead, determining for itself "the best interpretation," "the better reasoned interpretation," and "a common sense interpretation"); see also id. at 1098 (concluding that "[t]he intended scope of [the exemption] is not entirely clear" but not considering deference to the agency's position). In that regard, we agree with the Fourth Circuit that "[the] `functionally similar' inquiry cannot be squared with FLSA's plain statutory and regulatory language." Walton, 370 F.3d at 451. Nothing in the statutory text suggests that Congress meant to exempt salesmen, partsmen, mechanics, and any other employees with functionally similar job duties and pay structure; the text exempts only certain salesmen, partsmen, and mechanics.

The closer question is whether the agency's interpretation is unreasonable because it is unduly restrictive, as the Fourth Circuit held in Walton and the Montana Supreme Court held in Thompson.4 Those courts read § 213(b)(10)(A) as follows: "any salesman, partsman, or mechanic primarily engaged in [the general business of] selling or service automobiles." Service advisors are "salesmen" because their job is to sell services for cars. And service advisors are involved in the general business of "servicing automobiles," because their role is to help customers receive mechanical work on their cars. Accordingly, service advisors fall within the statutory definition. In effect, those courts held that that is the only reasonable reading of the statute.

The agency reads the statute differently: "any salesman, partsman, or mechanic primarily [and personally] engaged in selling or servicing automobiles." Service advisors may be "salesmen" in a generic sense, but they do not personally sell cars and they do not personally service cars. Accordingly, service advisors fall outside the statutory definition. In effect, the agency reads the statute as exempting salesmen who sell cars and partsmen and mechanics who service cars.

The Fourth Circuit rejected that interpretation as unreasonable because, with respect to "salesman," it purportedly reads out of the statute the second half of the disjunctive clause "`selling or servicing automobiles.'" Walton, 370 F.3d at 452 (emphasis by Walton) (quoting § 213(b)(10)(A)); see also Thompson, 294 P.3d at 402 ("A plain, grammatical reading of [the statute] makes clear that the term `salesman' encompasses a broader category of employees than those only engaged in selling vehicles" because of "[t]he use of the disjunctive `or' between the words `selling or servicing'"). The Fourth Circuit's point is that, when Congress uses a list of disjunctive subjects (here, "salesman, partsman, or mechanic") followed by a list of disjunctive verbs (here, "selling or servicing"), the ordinary interpretation of that construction is that each subject is linked with each verb. For example, if someone says, "if my dogs or cats are eating or drinking, then I know not to pet them," we understand that phrase to be all-encompassing: the speaker refrains from petting a dog that is eating or drinking and a cat that is eating or drinking. It would contravene the speaker's intent to include, for example, only cats that were eating but to exclude dogs that were eating.

Critically, however, that analysis depends on context. Consider this slightly modified hypothetical: "if my dogs or cats are barking or meowing, then I know that they need to be let out." The Fourth Circuit's grammatical interpretation of that phrase would include a meowing dog and a barking cat. But most English speakers would interpret the sentence to refer only to a barking dog and a meowing cat. At a minimum, that implicit limitation would offer a reasonable interpretation of the speaker's intent.

Returning to the statute at hand, the agency's interpretation is reasonable. A natural reading of the text strongly suggests that Congress did not intend that both verb clauses would apply to all three subjects. For example, it is hard to imagine, in ordinary speech, a "mechanic primarily engaged in selling ... automobiles." That is, it seems that Congress intended the subject "mechanic" to be connected to only one of the two verb clauses, "servicing." The nature of the word "mechanic" strongly implies the actions that the person would take — servicing. See American Heritage College Dictionary 842 (3d ed.2000) (defining "mechanic" as a "worker skilled in making, using, or repairing machines, vehicles, and tools"). The same can be said of the subject "salesman." It is hard to imagine, in ordinary speech, a "salesman ... primarily engaged in ... servicing automobiles." Congress likely intended the subject "salesman" to be connected to only one of the two verb clauses, "selling." The nature of the word "salesman" strongly implies the actions that the person would take — selling. See id. at 1203 (defining "salesman" as a "man who sells merchandise").

It is important to note that the agency's reading does not render any term meaningless or superfluous. All three subjects (salesman, partsman, and mechanic) and both verbs (selling and servicing) retain meaning; it is just that some of the verbs do not apply to some of the subjects. If the agency read out a word altogether, its interpretation likely would be unreasonable. See, e.g., Chubb Custom Ins. Co. v. Space Sys./Loral, Inc., 710 F.3d 946, 966 (9th Cir.2013) ("It is a well-established rule of statutory construction that courts should not interpret statutes in a way that renders a provision superfluous."), cert. denied, ___ U.S. ___, 134 S.Ct. 906, 187 L.Ed.2d 833 (2014). But the regulation does not run afoul of that doctrine.

Non-textual indicators of congressional intent, such as legislative history, are inconclusive. See Fournier v. Sebelius, 718 F.3d 1110, 1123 (9th Cir.2013) (holding that, at Chevron step two, "legislative history permissibly may be considered"), cert. denied, ___ U.S. ___, 134 S.Ct. 1501, 188 L.Ed.2d 378 (2014). We have found no mention, in the relevant reports or hearings, of service advisors, by name or by role. All references to "salesman" appear to refer to an employee who sells cars only. See, e.g., 112 Cong. Rec. S20,504 (Aug. 24, 1966) (statement of Sen. Yarborough) ("It would not affect the salesman. He can go out and sell an Oldsmobile, a Pontiac, or a Buick all day long and all night."); id. ("The salesman tries to get people mainly after their hours of work. In some cases a man will leave his job, get his wife, and go to look at automobiles. So the hours of a salesman are different.").

In 1961, Congress exempted "any employee" of a car dealership. 29 U.S.C. § 213(a)(19) (1961); Pub.L. No. 87-30, § 9, 75 Stat. 65 (1961). A few years later, the Eighty-Ninth Congress considered three bills on this topic. The first bill, introduced in 1965, would have repealed altogether the exemption for employees of dealerships. H.R. 8259, 89th Cong. § 305 (introduced in House on May 18, 1965). The next bill, also introduced in 1965, would have exempted from overtime requirements "any salesman or mechanic employed by" a car dealership. H.R. 10,518, 89th Cong. § 209 (introduced in House on Aug. 17, 1965); H.R. 10,518, 89th Cong. § 209 (reported in House on Aug. 25, 1965). Neither of those bills passed.

The final bill — H.R. 13,712 — was enacted into law on September 23, 1966.5 The first three versions, introduced in the first half of 1966, exempted either "any salesman or mechanic" or "any salesman, mechanic, or partsman" employed by a car dealership. H.R. 13,712, 89th Cong. § 209 (introduced in House on Mar. 16, 1965); id. (reported in House on Mar. 29, 1966); id. (referred in Senate on May 27, 1966). The final three versions all qualified the list of employees with the phrase, "primarily engaged in selling or servicing automobiles." Id. (reported in Senate on Aug. 23, 1966); id. (ordered to be printed in Senate on Aug. 25, 1966); Pub.L. No. 89-601 (Sept. 23, 1966). We know, then, that sometime in 1966 between May 27 and August 23, the Senate added that phrase. Unfortunately, the legislative history is silent on its meaning. See, e.g., 112 Cong. Rec. H21,940 (Sept. 7, 1966) (House Conference Report: "The conference substitute conforms to the House provision regarding partsmen, except that such exemption shall be available only to salesmen, partsmen, and mechanics primarily engaged in selling or servicing such vehicles."); 112 Cong. Rec. 522,651 (Sept. 14, 1966) ("The resulting language follows the House exemption — including the Senate floor amendment — but with a somewhat narrower scope."); Sen. Comm. on Lab. & Pub. Welf., Report No. 1487, p. 14, 89th Cong. (Aug. 23, 1966) ("Committee Report") ("Section 13(b) is amended to provide an overtime exemption for salesmen and mechanics who are primarily engaged in selling or servicing automobiles....").

The only possible exception, noted by Deel Motors, 475 F.2d at 1097 n. 2, is found in the Committee Report on August 23, 1966:

Committee Report at 32. The Fifth Circuit quoted selectively from that passage for the proposition that the committee intended to exempt all mechanics and salesmen. Deel Motors, 475 F.2d at 1097 n. 2. But the quoted passage also is found in earlier committee reports, which were written before the limiting phrase was added. E.g., Sen. Comm. on Educ. & Lab., Report No. 871, p. 38, 89th Cong. (Aug. 25, 1965). Because the passage appeared both before and after the addition of the "primarily" proviso, the best reading of that passage is that the committee was addressing what provisions apply to employees who work in separate buildings, not what types of salesmen are exempt.

In sum, there are good arguments supporting both interpretations of the exemption. But where there are two reasonable ways to read the statutory text, and the agency has chosen one interpretation, we must defer to that choice. Chevron, 467 U.S. at 844, 104 S.Ct. 2778. Accordingly, we hold that Plaintiffs are not exempt under 29 U.S.C. § 213(b)(10)(A).

Dismissal of claims 3, 5, and 7 AFFIRMED; dismissal of claim 1 and the supplemental state-law claims REVERSED; case REMANDED. Costs on appeal awarded to Plaintiffs.
