OPINION
delivered the opinion of the court,
We granted permission to appeal to determine: 1) whether an indirect purchaser may bring an action under the Tennessee Trade Practices Act against defendants involved in an price-fixing scheme; 2) whether the conduct complained of falls within the scope of the act; and 3) whether the trial court erred in declining to grant summary judgment to the defendants as to the plaintiffs unjust enrichment claim. We conclude that although an indirect purchaser may bring an action under the Tennessee Trade Practices Act, the conduct complained of in this case did not substantially affect Tennessee commerce and thus falls outside the scope of the act. We further conclude that to sustain an unjust enrichment claim, the plaintiff is not required to: 1) establish that the defendants received a direct benefit or 2) exhaust all remedies against the party with whom the plaintiff is in privity if the pursuit of the remedies would be futile. Because the plaintiff failed to provide a factual basis to support its bare allegation that any attempt to exhaust its remedies would have been futile, the trial court erred in failing to grant the defendants’ motion for summary judgment on the unjust enrichment claim. Accordingly, the judgment of the Court of Appeals is affirmed in part and reversed in part, and the case is remanded *516 to the trial court for further proceedings in accordance with this opinion.
Defendant Eastman Chemical Co. (“Eastman”) is a Delaware corporation with its principal place of business in Kingsport, Tennessee. Defendants Hoechst Aktiengesellschaft (“Hoechst”) and Nutrinova Nutrition Specialities & Food Ingredients, GmbH (“Nutrinova”) are German corporations with principal places of business in Frankfurt, Germany. Defendants Daciel Chemical Industries, Ltd. (“Daciel”) and Nippon Gohsei Industries, Ltd. (“Nippon”) are Japanese corporations with principal places of business in Tokyo and Osaka, Japan, respectively. Eastman, Hoechst, Nutrinova, Daciel, and Nippon (collectively “defendants”) are producers of sorbates. Sorbates are food preservatives used in small quantities in high-moisture and high-sugar products to slow the growth of mold.
Between 1998 and 2001, each defendant pleaded guilty to fixing the prices of sor-bates in violation of the Sherman Antitrust Act. See 15 U.S.C. § 1 (1997). The defendants also have settled federal lawsuits brought by a nationwide class of direct purchasers of sorbates as well as lawsuits brought by indirect purchasers in fourteen states, including Tennessee, and the District of Columbia.
Plaintiff Freeman Industries, LLC (“Freeman”) is a New York corporation with its principal place of business in Tuck-ahoe, New York. Freeman is an end-user of food products containing sorbates and purchases these products at supermarkets in New York. Freeman, as an indirect purchaser of sorbates, filed a lawsuit against the defendants claiming a violation of the Tennessee Trade Practices Act (“TTPA”), Tenn.Code Ann. § 47-25-101 et seq. (2001), and unjust enrichment.
The trial court granted the defendants’ motion to dismiss Freeman’s TTPA claim. The trial court concluded that the TTPA does not apply to indirect purchasers or to transactions occurring outside of Tennessee. The trial court denied the defendants’ motion for summary judgment as to Freeman’s unjust enrichment claim.
On interlocutory review, the Court of Appeals concluded that although indirect purchasers may recover under the TTPA, the act does not apply to indirect purchasers who are not “Tennessee consumers.” The Court of Appeals further concluded that Freeman could not recover under the TTPA because it failed to establish that it “had a transaction in Tennessee that was substantially affected by the defendants’ illegal conduct.” With respect to Freeman’s unjust enrichment claim, the Court of Appeals held that a plaintiff is not required to confer a direct benefit upon a defendant to proceed with a claim for unjust enrichment. The Court of Appeals therefore modified the portion of the trial court’s judgment that held that the TTPA is not applicable to indirect purchasers and affirmed the trial court’s judgment in all other respects. We granted review.
ANALYSIS
A. Tennessee Trade Practices Act
We must first decide whether the trial court erred in granting the defendants’ motion to dismiss Freeman’s TTPA claims pursuant to Tennessee Rule of Civil Procedure 12.02(6). A motion to dismiss a complaint for failure to state a claim pursuant to Rule 12.02(6) “admits the truth of all of the relevant and material allegations contained in the complaint, but it asserts that the allegations fail to establish a cause of action.”
Leach v. Taylor,
1. Indirect Purchasers
Tennessee Code Annotated section 47-25-106 (2001) provides for a civil remedy against those who violate the TTPA. Section 47-25-106 states that:
[a]ny person who is injured or damaged by any such arrangement, contract, agreement, trust, or combination described in this part may sue for and recover, in any court of competent jurisdiction, from any person operating such trust or combination, the full consideration or sum paid by the person for any goods, wares, merchandise, or articles, the sale of which is controlled by such combination or trust.
By providing a civil remedy to “[a]ny person who is injured or damaged” as the result of violations of the TTPA, the plain language of section 47-25-106 provides a cause of action to indirect purchasers.
See City of Cookeville ex rel. Reg’l Med. Ctr. v. Humphrey,
This Court has identified two purposes of the TTPA.
See Baird v. Smith,
The defendants contend that the language of Tennessee Code Annotated section 47-25-106 permitting recovery of “the full consideration or sum paid by the person” for the products, “the sale of which is controlled by such combination or trust,” *518 limits recovery to direct purchasers. According to the defendants, the only sale “controlled by” an antitrust violator is the transaction between the violator and the direct purchaser. We believe that their argument is flawed. First, “control” means “[p]ower or authority to manage, direct, superintend, restrict, regulate, govern, administer, or oversee” as well as “[t]he ability to exercise a restraining or directing influence over something.” Black’s Law Dictionary 329 (6th ed.1990). A sale “controlled by” an antitrust violation includes not only a sale made by the violator to the direct purchaser but also a transaction between the direct purchaser and the consumer in which the price of the product purchased by the consumer is influenced by the antitrust violator’s conduct.
Second, we believe that this language pertains not to persons who may recover but to the recovery itself. A plain reading of section 47-25-106 permits a person to recover the consideration or sum that was “controlled by” or influenced by the antitrust violator. In other words, an indirect purchaser may recover from the antitrust violator the amount of the overcharge that the direct purchaser passed on to the indirect purchaser. 2
Third, we conclude that the United States Supreme Court’s holding in
Illinois Brick Co. v. Illinois,
The Supreme Court’s holding in
Illinois Bñck Co.,
however, applies only to federal antitrust law. Clearly, states may provide a remedy to indirect purchasers under their own antitrust laws.
California v.
*519
ARC Am. Corp.,
In response to
Illinois Brick Co.,
many states amended their antitrust statutes to either provide indirect purchasers with a private right of action or permit the state’s attorney general to bring an action as
parens patriae
on behalf of indirect purchasers.

The defendants identify various failed attempts by the Tennessee legislature to amend the TTPA to expressly permit indirect purchaser claims in support of its contention that the TTPA does not currently provide for such suits. While legislative inaction is generally irrelevant to the interpretation of existing statutes, the legislature’s failure to “express disapproval of a judicial construction of a statute is persuasive evidence of legislative adoption of the judicial construction.”
Hamby v. McDaniel,
The present case, however, involves the Tennessee legislature’s failure to amend a state statute in response to a federal court’s interpretation of a federal statute. Furthermore, the United States Supreme Court has emphasized that its holding in
Illinois Brick Co.
applies only to federal antitrust law.
ARC America Corp.,
impossible to assert with any degree of assurance that [legislative] failure to act represents (1) approval of the status quo, as opposed to (2) inability to agree upon how to alter the status quo, (3) unawareness of the status quo, (4) indifference to the status quo, or even (5) political cowardice.
Johnson v. Transp. Agency Santa Clara County, Cal.,
Furthermore, unlike many states that have applied
Illinois Brick Co.
in disallowing indirect purchasers from bringing a private action under their antitrust laws, Tennessee does not have a statutory “harmony clause” mandating courts to interpret the TTPA consistently with federal law.
Cf. Stifflear v. Bristol-Myers Squibb Co.,
In addition, the concerns identified by the United States Supreme Court in
Illinois Brick Co.
do not justify prohibiting indirect purchaser suits under the TTPA. The Supreme Court expressed concerns regarding the possibility of multiple liability.
Illinois Brick Co.,
The Supreme Court also expressed concern regarding the decreased incentive for direct purchasers to bring suit.
Illinois Brick Co.,
Finally, the Supreme Court expressed concern regarding the risk of highly complex litigation due to the difficulty in apportioning damages.
Id.
at 745-47,
Accordingly, we conclude that an indirect purchaser may bring an action under Tennessee Code Annotated section 47-25-106 for conduct in violation of the TTPA even though the indirect purchaser is a non-resident of this state.
2. Scope of the TTPA
We must next determine whether the conduct complained of falls within the scope of the TTPA. Tennessee Code Annotated section 47-25-101 (2001) provides that
[a]ll arrangements, contracts, agreements, trusts, or combinations between persons or corporations made with a view to lessen, or which tend to lessen, full and free competition in the importation or sale of articles imported into this state, or in the manufacture or sale of articles of domestic growth or of domestic raw material, and all arrangements, contracts, agreements, trusts, or combinations between persons or corporations designed, or which tend, to advance, reduce, or control the price or the cost to *521 the producer or the consumer of any such product or article, are declared to be against public policy, unlawful, and void.
This Court last addressed the reach of the TTPA in
Standard Oil Co. v. State,
In
Standard Oil Co.,
this Court reasoned that the state legislature knew it did not have the power to enact laws that regulated interstate commerce and thus did not intend to enact unconstitutional law.
The language of Tennessee’s antitrust statutes have not changed significantly since
Standard Oil Co. Compare Standard Oil Co.,
The dual sovereignty theory presuming mutually exclusive jurisdiction for state antitrust laws and federal antitrust laws has since been rejected. The United States Supreme Court now considers state antitrust regulations to supplement and complement the federal antitrust laws and the enforcement of these state laws to be consistent with the federal antitrust laws.
See ARC Am. Corp.,
*522
In construing statutes, we must ascertain and give effect to the legislature’s intent and purpose. See
Lipscomb v. Doe,
The TTPA prohibits agreements adversely affecting competition in the “sale of articles imported into this state” or influencing the “price or the cost to the producer or the consumer of any such product or article.” Tenn.Code Ann. § 47-25-101 (2001). According to its plain language, the TTPA prohibits arrangements that decrease competition or affect the prices of goods even if those goods arrived in Tennessee through interstate commerce. The act does not contain any language indicating that the legislature intended that the scope of the act be limited to intrastate commerce. Had the legislature intended such a limitation, the legislature simply could have included the limitation in the act.
In developing a standard for determining the application of the TTPA to a particular set of circumstances, we must determine whether the focus should be upon the anticompetitive conduct of the defendant or the effects of the anticompetitive conduct. In examining whether the circumstances of a particular case fall within the TTPA, the Court of Appeals has employed a conduct-based test focusing upon the character of the defendant’s anticom-petitive conduct giving rise to the dispute.
See Lynch Display Corp. v. Nat’l Souvenir Ctr., Inc.,
Furthermore, the purpose of the TTPA is to protect the state’s trade or commerce affected by the anticompetitive conduct.
See State ex rel. Astor v. Schlitz Brewing Co.,
We must now determine the standard to employ in examining whether the effects of the anticompetitive conduct on Tennessee trade or commerce fall within the scope of the TTPA. One possible standard is a “predominant effects” standard. The term “predominant” is defined as “[something greater or superior in power and influence to others with which it is connected or compared.” Black’s Law Dictionary 1177 (6th ed.1990). Thus, anticompetitive conduct cannot predominantly affect both intrastate commerce and interstate commerce. Under a “predominant effects” standard, courts would be required to *523 weigh the effects of anticompetitive conduct on Tennessee commerce against its effects on interstate commerce and determine which effects are greater. If the effects on interstate commerce are greater than the effects on Tennessee commerce, the TTPA would not apply.
In construing the TTPA, other jurisdictions have utilized a “predominant” standard in applying a conduct-based test.
See e.g., In re Terazosin Hydrochloride Antitrust Litig.,
We conclude that the proper standard for determining whether a case falls within the scope of the TTPA is a “substantial effects” standard. Pursuant to this standard, courts must decide whether the alleged anticompetitive conduct affects Tennessee trade or commerce to a substantial degree. Federal courts have applied the substantial effects standard to the Sherman Antitrust Act.
See Hartford Fire Ins. Co. v. California,
The determination of whether an effect is substantial does not involve “mathematical nicety.”
Anesthesia Advantage, Inc. v. Metz Group,
In the present case, Freeman alleges that Eastman engaged in conduct from its principal place of business in Kingsport, Tennessee, including: 1) communicating with its co-defendants through in-person meetings, telephone calls, letters, and email resulting in an agreement to fix the prices of sorbates; 2) implementing the agreement by drafting price schedules and letters to third parties, adjusting prices and production volumes of sorbates, and taking orders and implementing sales to customers at the new prices; and 3) attempting to conceal its conduct by limiting the number of its employees having knowledge of the agreement. These allegations primarily relate to the defendants’ actions in conspiring and implementing the conspiracy to fix the prices of sorbates.
The focus under the substantial effects standard, however, is not on the anticom-petitive conduct itself but on the effects of the conduct on Tennessee commerce. While Freeman alleged that Eastman took orders and implemented sales to customers at the new prices from Tennessee, we do not believe that this bare allegation without more is sufficient to establish that Tennessee commerce was substantially affected. Furthermore, Freeman fails to establish how the defendants’ anticompeti-tive conduct affected Tennessee commerce to a substantial degree even though the conduct resulted in Freeman paying higher prices to retailers for items containing sorbates. To the contrary, there is no indication that the items that Freeman purchased contained sorbates manufactured by Eastman, the lone defendant with ties to Tennessee. Therefore, we conclude that Freeman’s claim does not fall within the scope of the TTPA and that the trial court properly granted the defendants’ motion to dismiss Freeman’s claim.
B. Unjust Enrichment
We must next determine whether the trial court erred in denying the defendants’ motion for summary judgment regarding Freeman’s claim of unjust enrichment. Summary judgment is appropriate only when the moving party demonstrates that no genuine issues of material fact exist and’-that the moving party is entitled to judgment as a matter of law.
See
Tenn. R. Civ. P. 56.04;
Penley v. Honda Motor Co.,
We have previously recognized two types of implied contracts: contracts implied in fact and contracts implied in law.
See Paschall’s, Inc. v. Dozier,
The elements of an unjust enrichment claim are: 1) “[a] benefit conferred upon the defendant by the plaintiff’; 2) “appreciation by the defendant of such benefit”; and 3) “acceptance of such benefit under such circumstances that it would be inequitable for him to retain the benefit without payment of the value thereof.”
Paschall’s, Inc.,
A plaintiff need not be in privity with a defendant to recover under a claim of unjust enrichment.
See Paschall’s, Inc.,
The defendants further contend that Freeman failed to establish that it exhausted its remedies against the supermarket from which it purchased the food products that contained sorbates. The defendants submitted various affidavits to demonstrate that Freeman had not sought to recover from the supermarket. We conclude that through these affidavits, the
*526
defendants have negated the exhaustion of remedies element of Freeman’s unjust enrichment claim. Thus, the burden shifts to Freeman to provide specific facts establishing the existence of disputed issues of material fact that must be resolved by the trier of fact.
See Blair v. West Town Mall,
In response, Freeman submitted an affidavit from its counsel maintaining that he was unaware of any viable claims against the supermarket. Freeman essentially contends that pursuit of any causes of action against the supermarket would have been futile. Although our courts have not addressed the issue of futility with regard to the exhaustion of remedies element of an unjust enrichment claim, our courts have recognized this exception in other causes of action with an exhaustion of remedies requirement.
See e.g., Wilson v. Miller,
CONCLUSION
We conclude that although Freeman may bring a claim against the defendants under the TTPA as an indirect purchaser, the conduct of which Freeman complains does not fall within the scope of the act because Tennessee commerce was not substantially affected by the conduct. As to the unjust enrichment claim, we hold that Freeman was not required to establish that the defendants directly benefitted from the transaction between Freeman and the supermarket. We further hold, however, that the trial court erred in declining to grant the defendants’ motion for summary judgment as to the unjust enrichment claim due to Freeman’s failure to provide a factual basis to support its allegation that any attempt to exhaust its remedies against the supermarket would have been futile. Accordingly, we affirm the judgment of the Court of Appeals in part and reverse in part, and we remand the case to the trial court for further proceedings consistent with this opinion.
The costs of appeal are taxed to the appellant, Freeman Industries, and its sureties, for which execution may issue if necessary.
Notes
. Tennessee Code Annotated section 47-25-101 (2001) provides that
All arrangements, contracts, agreements, trusts, or combinations between persons or corporations made with a view to lessen, or which tend to lessen, full and free competition in the importation or sale of articles imported into this state, or in the manufacture or sale of articles of domestic growth or of domestic raw material, and all arrangements, contracts, agreements, trusts, or combinations between persons or corporations designed, or which tend, to advance, reduce, or control the price or the cost to the producer or the consumer of any such product or article, are declared to be against public policy, unlawful, and void. Tennessee Code Annotated 47-25-102 prohibits agreements "to sell and market ... products and articles, manufactured in this state, or imported into this state, to any producer or consumer at prices reduced below the cost of production or importation into this state.” The statute further prohibits "any other arrangements, contracts, or agreements, by and between its agents and sub-agents, which tend to lessen full and free competition in the sale of all such articles manufactured and imported into the state, and which amount to a subterfuge for the purpose of obtaining the same advantage and purposes.”
. The defendants contend that permitting Freeman to recover the full consideration that it paid to the direct purchaser for the food products violates the constitutional principles of fairness and due process. Because we interpret Tennessee Code Annotated section 47-25-106 as permitting Freeman to recover only the amount of the overcharge that the direct purchaser passed on to Freeman, we need not reach this issue.
. Section 4 of the Clayton Act, 15 U.S.C. § 15, provides: [A]ny person who shall be injured in his business or property by reason of anything forbidden in the antitrust laws may sue therefor in any district court of the United States in the district in which the defendant resides or is found or has an agent, without respect to the amount in controversy, and shall recover threefold the damages by him sustained, and the cost of suit, including a reasonable attorney’s fee.
