In this appeal, we determine the appropriate test for applying an enhancement under the United States Sentencing Guideline (“U.S.S.G.”) § 2B6.1 for being “in the business of receiving and selling stolen property.” We also decide whether the enhancement applies to a thief’s wife who: (1) submitted fraudulent paperwork to register at least twenty vehicles stolen by her husband over a ten-year period; (2) conveyed title to, and accompanied her husband in delivering, the vehicles to buyers; (3) permitted some of the vehicles to be kept on her property; and (4) drove at least one of the stolen vehicles. The sentencing court applied the enhancement. Because we find that the defendant both received and sold stolen property with regularity and sophistication, we AFFIRM.
I. BACKGROUND
Sharon Saunders, the wife of Terence James Saunders, 1 pled guilty to one count of possessing with intent to sell motor vehicles with altered vehicle identification numbers, in violation of 18 U.S.C. § 2321(a). She now appeals her eighteen-month sentence pursuant to 18 U.S.C. § 3742(a)(2) on the ground that the district court incorrectly applied the enhancement under U.S.S.G. § 2B6.1(b)(2) for being in the business of receiving and selling stolen property (“in the business enhancement”).
Over a span of ten years, Sharon’s husband stole more than seventy vehicles. Together they altered their production dates to make them ten years or older, which allowed them to be registered without any title documentation. They would then change the identification numbers of, obtain State of Georgia registrations for, and sell the vehicles to unsuspecting third parties or keep them for personal use. Sharon’s specific role was to assist in applying for and obtaining documents for the vehicles in three Georgia counties, knowing they were stolen and had altered and fraudulent identification numbers. She was driving one of the stolen vehicles, which was licensed in her name, just before her arrest and she permitted some stolen vehicles to be kept on her property. Her signature was found on the bills of sale for at least twenty-seven vehicles and she accompanied her husband in transporting some of them for delivery to their purchasers.
The probation officer recommended the enhancement. At the sentencing hearing, Sharon objected, arguing that she had been a homemaker and financially dependent on her husband. In overruling her objections, the district court determined that:
*1262 [Sharon] was in the business; and, under [either] conspiracy theory, Pinkerton theory, aiding and abetting theory, co-conspirator theory, [or] actual possession and constructive possession theory, she possessed one or more of these trailers and was in the business of selling them after they had been stolen by her husband. She was an intеgral part of that procedure. Without her, a direct number of these would not have gone through.
R5-9-10. The court sentenced Sharon to eighteen months of incarceration, noting that the sentence would have been at the high end of the guidelines range had the two-level enhancement not been applied. 2 Sharon timely appealed, arguing that the district court used the wrong standard for applying the enhancement and that, even had the correct standard been applied, the evidence would have been insufficient to prove that Sharon had received the vehicles or that she was in the business of fencing stolen property. 3
II. DISCUSSION
Section 2B6.1(b)(2) of the Guidelines, applicable to convictions under 18 U.S.C. § 2321(a), provides a two-level enhancement to the base offense level, imposed for altering or removing motor vehicle identification numbers, or trafficking in motor vehicles or parts with altered or obliterated identification numbers, “[i]f the defendant was in the business of receiving and selling stolen property.” U.S.S.G. § 2B6.1(b)(2) (2001). 4 The Commentary provides no clarification of the enhancement or definition for being “in the business.” 5 See U.S.S.G. § 2B6.1, comment. We, also, have not particularized the appropriate test for applying the enhancement.
Initially, we must determine whether the district court used an incorrect standard, as Sharon argues, when it concluded that she was an “integral part” of her husband’s illegal operation and necessary
*1263
for its success. She contends that the correct standard is whether she personally participated in the scheme in a manner sufficient to trigger application of the enhancement. We agree. In
United States v. Maung,
Sharon next argues that, even if the court did not use an incorrect standard, it erroneously applied the standard to the facts of her case. “When a dеfendant challenges the district court’s application of the sentencing guidelines, we review the district court’s underlying findings of fact for clear error and application of the guidelines to those facts de novo.” Id. at 1118. We have never before had an opportunity to fully develop the appropriate test for applying the enhancement. We do so now. 6
[T]he circuits have split on the proper test for determining whether a defendant, who was not the actual thief, 7 was “in the business” or not [under a similar enhancement in § 2B1.1], Two tests have emerged. The “fence” test, adopted by the Fifth, Sixth, and Seventh Circuits, requires proof that the defendant was a person who bought and sold stolen property, and thereby encouraged others to commit property crimes. The “totality of the circumstances” test, embraced by the First, Third, and Ninth Circuits, and perhaps by the Second Circuit, employs a “case by case approach with emphasis on the ‘regularity and sophistication of a defendant’s [criminal] operation.’ ”
Maung,
Effective 1 November 2001, the Sentencing Commission resolved the circuit split and revised the commentary to § 2B1.1, a guideline addressing “basic forms of property offenses.” U.S.S.G. Ch.2, Pt. B.l intro, comment. In doing so, the Commission “clariffied] the meaning of ‘person in the business of receiving and selling stolen property’ ” and adopted the totality of the circumstances approach. 8 *1264 U.S.S.G.App. C, Amend. 617 at 182 (2001). No such clarification exists for § 2B6.1(b)(2). Thus, as a preliminary matter, we must decide whether the Sentencing Commission intended to extend the meaning it attributed to the enhancement under § 2Bl.l(b)(4) to that under § 2B6.1(b)(2).
“[W]here the guidelines provide no indication as to a particular application the Court looks to the language and purpose of the Sentencing Guidelines for instruction.”
United States v. Pompey,
Here, however, the clarifying words are not used the same in the two different sections. In fact, the Sentencing Commission amended § 2B1.1 with language clarifying the enhancement but did not similarly amend § 2B6.1, even though its language and structure are virtually identical and the underlying offenses conceptually similar. “ ‘[W]here Congress includes particular language in one section of a statute but omits it in anothеr section of the same Act, it is generally presumed that Congress acts intentionally and purposely in the disparate inclusion or exclusion.’ ”
Russello v. United States,
*1265 A. Proper Test for Applying the Enhancement
1. The “in the business” Test
Based on our own analysis, we now adopt the totality of the circumstances test for applying the two-level enhancement set out in § 2B6.1(b)(2) for being “in the business of receiving and selling stolen property.” Under the “fence test,” “the sentencing courts merely examine[] the defendant’s operation to determine: (1) if stolen property was bought and sold, and (2) if the stolen property transactions encouraged others to commit property crimes.”
United States v. Warshawsky,
The Sentencing Commission has decided that fences deserve longer sentences than mere thieves because a sentence based solely on “the amount of (stolen) property” recovered by the police “is likely to underrepresent the scope of their criminality and the extent to which [the defendant] encourage[s] or facilitate[s] other crimes.”
Warshawsky,
By contrast, circuits adopting the totality of the circumstances test “undertake a case-by-case approach, weighing ... [all] the circumstances, with particular emphasis on the regularity and sophistication оf a defendant’s operation.”
United States v. St. Cyr,
Nevertheless, a sentencing court can certainly consider evidence about the amount of income generated through fencing activities, the defendant’s past activities, his demonstrated interest in continuing or expanding the operation, and the value of the property handled. Where there is no indication either of a pattern of dealing in stolen property or of a developed operation that promises such consistency for the future, the defendant is unlikely to be “in the business.” ... [C]ourts have insisted that more than isolated, casual, or sporadic activity be shown before a business is found to exist.
*1266
Id.
at 703-04 (citations omitted).
11
The sophistication of the defendant’s operations is also important and “may itself indicate business conduct ... [as] a meaningful proxy for regularity, say, by showing that the operation crossed a threshold of sophistication and commitment.”
12
Id.
at 704;
see also United States v. Cottman,
We adopt the totality of the circumstances test for several reasons. First, determining the regularity and sophistication of a defendant’s fencing operation, though inherently subjective, is far less so than deciphering to what extent the operation encourages subsidiary, future crimes. For the same reason, it is also more lenient on defendants. Moreover, the policy rationale on which courts such as War-shawsky relied in developing the fence test has subsequently been withdrawn from the guidelines сommentary in 1993 when §§ 2B1.1 and 1.2 were consolidated. Concluding that there was never a bright line for applying the enhancement, the First Circuit in St. Cyr noted:
[The commentary] proves too much.... [E]ven purchasers of stolen goods who never sell and sellers of stolen goods who never purchase can strengthen the black market and thereby facilitate other crime_ It is almost always possible to argue that the conduct for which a defendant has been convicted is likely to underrepresent his *1267 entire criminal career or his contribution to a general subculture of criminality. There is no sound basis on which trafficking in stolen goods, per se, can be singled out in this respect.
2. The Fence Requirement
Because Sharon also attacks the district court’s application of the enhancement on the ground that she was not a fence, we address whether the totality of the circumstances test operates to the exclusion of the first prong of the fence test: whether stolen рroperty was actually bought and sold. In short, can the enhancement be applied where the defendant was either a seller who did not receive or a receiver who did not sell? We hold that it cannot; a prerequisite to the application of the two-level enhancement in § 2B6.1(b)(2) is that the defendant personally received and sold stolen property.
In considering this question, we look first to the plain language and ordinary meaning of the enhancement.
See United States v. Singh,
The structure of the guidelines and “parallel development of the [other] sentencing guideline governing thefts of property” are also instructive.
McMinn,
We also look to the underlying purpose of the enhancement.
See Singh,
[In this regard t]he services of a professional fence undoubtedly facilitate the ready, advantageous disposition of property stolen by the less well-situated thief.... Furthermore, the interposition of a soрhisticated fencing operation between the thief and the ultimate purchaser of the stolen property may confound or obstruct the investigation and prosecution of theft offenses ... [as] the loot is more likely to be dispersed before law enforcement agencies can respond.
McMinn,
Moreover, we said in
Maung
that “[a] defendant who has not received and sold cannot be ‘in the business of receiving and selling.’”
Finally, we note that an interpretation of the enhancement requiring that the defendant be a fence is not inconsistent with our adoption of the totality of the circumstances test for applying the enhancement. The fence test has two prongs.
16
The first requires the receipt and sale of stolen goods as a threshold requirement, the second, the facilitation of theft and other crimes. It is the second prong that distinguishes the fence test from the totality of the circumstances test because it sets out the touchstone for determining whether the defendant was actually “in the business.” That the defendant must also re
*1269
ceive and sell stolen goods is the common denominator between the two tests. The decisions of the First Circuit most clearly illustrate this proposition. In
St. Cyr,
the court rejected the fence test and adopted the totality of the circumstances test.
Other courts agree. “Although some Circuits have described the ‘totality of the circumstances’ approach, upon which this Court relies, as a ‘competing test,’ ... [we are not] foreclose^] ... from requiring in the future that a defendant be a ‘fence’ for the enhancement to apply.”
Cottman,
B. Application of the Enhancement
Here, the district court’s factual findings were not clearly erroneous and justified application of the two-level enhancement.
18
We first examine the facts
*1270
supporting the conclusion that Sharon both received and sold stolen cars and then proceed to the totality of the circumstances inquiry as to the regularity and soрhistication of the operation, keeping in mind that “[t]he Government bears the burden of establishing by a preponderance of the evidence the facts necessary to support a sentencing enhancement.”
United States v. Askew,
We first determine whether Sharon sold the stolen vehicles. In
Maung,
we refused to enhance the defendant’s sentence under § 2B6.1(b)(2) because he was not personally involved in selling the stolen vehicles.
A defendant is not entitled to immunity from the enhancement only by virtue of his or her status as a homemaker. However, spousal financial dependence, alone, is also insufficient to conclude that the defendant enjoyed the proceeds of an illegal operation conducted by his or her spouse and therefore was “in the business.” It does not rise to the level of the type of partnership envisioned in
United States v. Collins,
Sharon’s conduct, however, went beyond mere paperwork or dependence on the illegal proceeds. First, her signature appeal's on the bills of sale for twenty-seven of the vehicles. At sentencing, defense counsel conceded that Sharon “had to sign [the vehicles] out and sign them over to the Florida Pine Straw people, and then they would issue the check thereto.” R5-8. While, “receiving goods and having them loaded into containers, as well as completing the necessary exportation paperwork” may not be selling stolen property,
Maung,
We also find that Sharon received stolen vehicles. On appeal, she argues that, because her husband personally stole the vehicles, he was not а fence and, therefore, neither was she, since her “criminal liability flows from the assistance she provided her husband.”
23
Reply Br. at 8. It is true that the act of receiving stolen goods is commonly understood as distinct from the initial theft. “Under the common-law tradition, stealing property from another normally does not equate with ‘receiving’ property from its rightful owner.”
McMinn,
*1272
The evidence demonstrates, however, that Sharon did receive stolen vehicles. We have said “that the Congress did not intend a limited, technical definition of the word ‘receive.’ We believe that accepting a good and having either physical control of or apparent legal power over a good is sufficient to show that an individual rеceived it.”
United States v. Strauss,
Here, it is undisputed that some of the stolen vehicles were titled in Sharon’s name and that she fraudulently registered at least twenty of the stolen vehicles in Georgia and kept some of the vehicles on her property. Thus, she had apparent legal control over them. That she possessed the vehicles in this manner and did not herself steal them also gives rise to circumstantial evidence of prior receipt. Moreover, case law has generally held that “it is immaterial from whom ... [stolen goods] are received ... [and] it makes no difference whether [the] accused, in receiving the goods, acted for himself or merely as [an] agent for another.” 76 C.J.S. Receiving Stolen Goods § 6. The fact that Sharon obtained control over the vehicles, and accepted the vehicles, from her own husband-thief is therefore inconsequential. 24
*1273 Having concluded that Sharon received and sold stolen vehicles and therefore acted as a fence, we now inquire whether, under the totality of the circumstances, Sharon was “in the business of receiving and selling stolen vehicles.” We pay particular attention to the regularity and sophistication of the illegal operations. Because Sharon conceded at the plea colloquy that her knowingly illegal activities spanned at least four and one-half years аnd admitted a total loss to her victims of $259,203.56, we do not hesitate in concluding that her fencing activities were regular, frequent and voluminous. Additionally, the facts that (1) the vehicles’s paperwork was altered to indicate that they were more than ten years old, (2) the vehicles were registered in Georgia so that it would be unnecessary to obtain a title for them, and (8) the defendants involved at least one other co-conspirator in their activities, indicate the necessary degree of sophistication. Accordingly, the district court did not err in enhancing Sharon’s sentence under § 2B6.1(b)(2).
III. CONCLUSION
We have determined that in applying the two-level enhancement under § 2B6.1(b)(2) for being “in the business of receiving and selling stolen property,” the defendant must have, at a minimum, acted as a fence. Beyond that, the sentencing court must examine the totality of the circumstances with a particular emphasis on the regularity and sophistication of the illegal activity to determine whether the defendant’s conduct amounted to a fencing business. This inquiry may include other
factors such as the value of the stolen property, the defendant’s past activities involving stolen property and the extent to which the illegal operations encouraged or facilitated other criminal activity. As we have explained, the defendant here obtained title and registration for, and signed the bills of sale transferring ownership of, some of the stolen vehicles. Furthermore, her illegal conduct spanned almost five years and caused hundreds of thousands of dollars of loss to her victims. Because the enhancement was correctly applied by the district court, we AFFIRM.
Notes
. Because the facts of this appeal involve a husband and wife with the same last name, we will refer to Mrs. Saunders as "Sharon” throughout this opinion.
.Without the enhancement, the offense level would have been thirteen and, with a criminal history category of I, a guidelines range of twelve to eighteen months. With the enhancement, the offense level was fifteen and the range eighteen to twenty-four months. We have held that a defendant may appeal a sentence even if it falls within the guidelines ranges advocated by both parties,
United States v. Fuente-Kolbenschlag,
. In her objections to the Presentence Investigation Report ("PSR"), Sharon argued that, because she did not plead guilty to the conspiracy count dropped by the prosecution pursuant to her plea bargain, the specific offense characteristics under § 2B6.1(b)(2) could not apply to her. On appeal, she does not renew this argument and, therefore, it is not before us.
. The probation officer relied upon the Guidelines Manual that became effective on 1 November 2000. Although Sharon's sentencing hearings began in October 2001, she was not actually sentenced until 6 December 2001. Because "[t]he court shall use the Guidelines Manual in effect on the date that the defendant is sentenced,” § 1B1.11, we reference the Manual effective on 1 November 2001 throughout this opinion. The 2001 version involved no substantive changes to § 2B6.1.
. As we discuss, however, an amendment to an identical enhancement in § 2B1.1(b)(4)(B) affects the analysis as a clarifying amendment.
. In
Maung,
we reversed the defendant's sentence because we found that he had not personally participated in the business of receiving and selling stolen property.
. Courts "generally have agreed that a thief who sells goods that he himself has stolen is not ‘in the business of receiving and selling stolen property.’ ”
Maung,
.Section 2B 1.1 (b)(4) provides: "If the offense involved receiving stolen property, and the defendant was a person in the business of receiving and selling stolen property, increase by 2 levels.” After the amendment, the commentary instructs courts to consider a "non-exhaustive list of factors in determining whether the defendant was in the business of receiving and selling stolen property”:
(A) The regularity and soрhistication of the defendant’s activities.
*1264 (B) The value and size of the inventory of stolen property maintained by the defendant.
(C) The extent to which the defendant’s activities encouraged or facilitated other crimes.
(D) The defendant’s past activities involving stolen property.
U.S.S.G. § 2B1.1, comment, (n. 4). Amendments to the commentary are generally binding.
Stinson v. United States,
. We nevertheless note the striking similarities between the two sections. Aside from language in § 2B 1.1(b)(4) limiting its application to offenses involving receiving stolen property, the texts of the two enhаncement provisions are identical. In addition, § 2B1.1 "covers offenses involving altering or removing motor vehicle identification numbers, trafficking in automobiles or automobile parts with altered or obliterated identification numbers,” the same offense as in § 2B6.1. U.S.S.G. § 2B1.1, comment, (backg’d.). Finally, for the purpose of grouping multiple counts, the guidelines require that §§ 2B1.1, 6.1 be grouped together under § 3D1.2(d). Because of these similarities, our opinion in *1265 Mating draws freely from decisions in other circuits that address the enhancement under § 2B1.1(b)(4). We do also, but do not find that mere reliance on the analysis in nonbinding precedent addressing this similar enhancement requires us to adopt § 2Bl.l's commentary for use in § 2B6.1.
. For other cases applying the fence test,
see, e.g., United States v. Myers,
. Courts have generally held that evidence of fencing operations prior to that charged in the indictment is not required.
See, e.g., United States v. Cottman,
. The Second Circuit has held that taking sophistication into account in applying the enhancement also does not constitute impermissible “double counting” of the base offense level.
See United States v. Salemi,
.For cases applying the totality of the circumstances test,
see, e.g., United States v. Coviello,
. As noted below, while the language of the commentary has been withdrawn, we find that the underlying purpose of the enhanсement — to punish fences more severely — survives.
. Although this language no longer appeared after the consolidation of §§ 2B1.1 and 2B1.2 in 1993, there is no reason to suppose that the omission was motivated by a desire to abolish or modify the underlying legislative purpose.
But see United States v. Richardson,
. See infra p. 1265.
.
See, e.g., Coviello,
. In her reply brief, Sharon obliquely makes the argument that the district court failed to make explicit findings of fact and conclusions of law. Reply Br. at 6 n. 3. Yet, we have observed that “[w]hen the court mandates no departure [from the applicable guidelines range], the sentencing judge need not offer further reasons justifying the sentence.”
United States v. West,
. We did not mean to suggest that these are the only two factors that could implicate a defendant in selling stolen property.
. She also argued at sentencing that the court should consider a downward departure both because she committed the acts under the duress of physical threats from her husband, see U.S.S.G. § 5K2.12 (2001), and because her conduct constituted aberrant behavior. See U.S.S.G. § 5K2.20. Even though the court took these arguments into account in determining the sentence within the applicable guidelines range, it declined to grant Sharon the downward departures she requested and this is not before us on appeal. Although Sharon's counsel makes a plausible argument that there could be no real partnership where Sharon succumbed to the physical intimidation of her husband, the enhancement makes no accommodation for duress and coercion other than the downward departure in § 5K2.12.
. As to Sharon's argument that the government did not prove that she knowingly transported the vehicles, her counsel’s admission at sеntencing as to her state of mind speaks for itself: "[A]t first there was no suspicion, then there was some suspicion, and then there was willful blindness, knowing that he[r husband] couldn't be coming up with that many good deals, and then to the point of where he had Ms. Saunders actually get some vehicles or trailers titled in her name.” R4-6.
. Sharon contends, however, that any concession made during the plea colloquy was "undercut by the fact that neither the Government nor the district court relied upon it at the sentencing.” Reply Br. at 7. Sharon cites no authority for this proposition, nor are we able to find any. Moreover, we have said that "[t]he findings of fact of the sentencing court may be based on evidence heard during trial, facts admitted by a defendant’s plea of guilty, undisputed statements in the presen-tence report, or evidence presented at the sentencing hearing.”
United States v. Wilson,
.It is unnecessary to apply a "plain error” analysis to this argument because we will assume that, in objecting to the enhancement itself, defense counsel properly objected at sentencing to the implicit finding that Sharon was also a fence.
. Thus, a person who acts as the agent of a thief when selling stolen property can be guilty of "receiving” that property from the thief where the other elements of the offense are met. Although there appears to be no federal cases addressing this precise issue, we have said that it is "[in]significant how [an] accused [charged with transporting stolen goods] acquired possession of the[m].”
Johnson v. United States,
