The only issue before us is whether the trial court erred in denying plaintiffs’ motion for summary judgment and granting defendants’ motion for summary judgment. Plaintiffs argue that the summary judgment order was in error because the insurance regulatory charge is a tax and its exclusion from the retaliatory tax computation violates the federal and state constitutions. After careful consideration of the record, briefs and contentions of the parties, we affirm.
Plaintiffs’ first argument is that the regulatory charge is a tax. Plaintiffs make five contentions. First, plaintiffs contend that the statutes show that the regulatory charge is a tax. The plaintiffs claim that statutes denominate the charge as a tax, it is measured like a tax, it is levied during the “taxable year,” and it appears in the General Statutes under “License Fees and Taxes” and is the only item in the Article that is not clearly a fee. Second, plaintiffs contend that case law requires the regulatory charge to be treated as a tax. Plaintiffs rely on American Equitable Assurance Co. of N.Y. v. Gold, 249 N.C. 461, 465, 106 S.E.2d 875, 878 (1959) to contend that a levy must be treated as a tax unless the legislature specifically makes its payment a condition of writing insurance. Plaintiffs argue that there is no statement in the statute making payment of the regulatory charge a condition of writing insurance. Third, plaintiffs urge that “the collection of a tax for a designated use does not make it less a tax,” and conclude that “ ‘taxes’ are not limited to levies that fall on all taxpayers or that are available for all governmental uses.” Fourth, plaintiffs argue that the regulatory charge was not a user fee, because it was not a quid pro quo for anything received by the plaintiff. Plaintiffs maintain that it was just a tax to raise revenue. Plaintiffs argue that North Carolina Ass’n of ABC Boards v. Hunt, 76 N.C. App. 290, 332 *167S.E.2d 693, disc. rev. denied, 314 N.C. 667, 336 S.E.2d 400 (1985), cited by defendants, should be limited to its facts. Finally, plaintiffs urge that this Court “should discourage legislative legerdemain.” Plaintiffs argue that this Court need not determine the purpose of the charge and the Insurance Fund, but need only conclude that the charge was a tax because it was not a license fee or a user fee.
Once the insurance regulatory charge is determined to be a tax, plaintiffs next argue that the retaliatory tax violates the equal protection clause of the Constitution because it is a discriminatory tax with no legitimate purpose. See Metropolitan Life Ins. Co. v. Ward, 470 U.S. 869, 84 L.Ed.2d 751, reh’g denied, 471 U.S. 1120, 86 L.Ed.2d 269 (1985). Plaintiffs argue that retaliatory taxes are allowed only if they reach parity of treatment. “[T]he imposition of retaliatory tax beyond the point of equalization solely to generate revenue at the expense of foreign insurers lacks legitimacy.” United Services Auto. Ass’n v. Curiale, 88 N.Y.2d 306, 313, 668 N.E.2d 384, 388, 645 N.Y.S.2d 413, 417 (1996).
Defendants argue that the regulatory charge is not a tax. They contend that because the charge is neither levied nor collected as a contribution to the maintenance of the general government, the regulatory charge does not constitute a tax. Proceeds from the regulatory charge do not go to the “general fund of the state” for the general maintenance of the government, but to a special discrete fund maintained by the State Treasurer, the Department of Insurance Fund. Defendants rely on North Carolina Ass’n of ABC Boards v. Hunt, 76 N.C. App. 290, 332 S.E.2d 693, disc. rev. denied, 314 N.C. 667, 336 S.E.2d 400 (1985). Defendants contend that the holding of Hunt was that a surcharge on liquor was not a tax, because the statute imposed “only the cost of regulation,” and the revenue from the surcharge did not go “to the general maintenance and expense of government.” Id. at 293, 332 S.E.2d at 695. See also Memphis Natural Gas Co. v. McCanless, 183 Tenn. 635, 651, 194 S.W.2d 476, 483 (1946) (“To be properly defined as ‘taxes’ the fees must be paid into the public treasury as a part of the general revenue and be subject to disbursement for the ‘general public need.’ ”). Accordingly, defendants argue that the regulatory charge is not a tax and that the trial court’s order should be affirmed.
The key issue here is whether the regulatory charge is a tax. In comparing taxes with regulatory fees, the court in San Juan Cellular Telephone Co. v. Public Service Com’n of Puerto Rico, 967 F.2d 683 (1st Cir. 1992) stated:
*168The classic ‘tax’ is imposed by a legislature upon many, or all, citizens. It raises money, contributed to a general fund, and spent for the benefit of the entire community. The classic ‘regulatory fee’ is imposed by an agency upon those subject to its regulation. It may serve regulatory purposes directly by, for example, deliberately discouraging particular conduct by making it more expensive. Or, it may serve such purposes indirectly by, for example, raising money placed in a special fund to help defray the agency’s regulation-related expenses.
Id. at 685 (citations omitted) (emphasis added). In applying San Juan Cellular to determine whether a charge is a tax, courts have developed a three-part test considering “(1) the entity that imposes the assessment; (2) the parties upon whom the assessment is imposed; and (3) whether the assessment is expended for general public purposes, or used for the regulation or benefit of the parties upon whom the assessment is imposed.” Bidart Brothers v. California Apple Commission, 73 F.3d. 925, 931 (9th Cir. 1996). See also Cumberland Farms, Inc. v. Tax Assessor, State of Maine, 116 F.3d 943 (1st Cir. 1997).
Applying the San Juan Cellular test, we hold that the regulatory charge imposed by G.S. 58-6-25 is not a tax. We note that the charge imposed here is imposed by the General Assembly, not by an administrative agency. This factor weighs in favor of a finding that the charge is a tax. See Bidart, 73 F.3d at 931. However, this factor is not dispositive. While the charge is imposed by the General Assembly, it is also imposed only upon insurance companies. “An assessment imposed upon a broad class of parties is more likely to be a tax than an assessment imposed upon a narrow class.” Id. Accordingly, after applying the first two prongs of the San Juan Cellular test, the nature of the regulatory charge remains somewhat unclear. “Where the first two factors are not dispositive, courts examining whether an assessment is a tax ‘have tended ... to emphasize the revenue’s ultimate use.’ ” Bidart, 73 F.3d at 932 (quoting San Juan Cellular, 967 F.2d at 685) (emphasis added). See also Cumberland Farms, 116 F.3d at 947 (“the most salient factor in the decisional mix concerns the destination of the revenues raised by the impost”).
In determining the nature of the regulatory charge under the final prong of the San Juan Cellular test, we find persuasive the Texas Court of Appeals decision in Prudential Health Care Plan, Inc. v. Commissioner of Insurance, 626 S.W.2d 822 (1981). In Prudential, *169Prudential Health Care Plan, Inc. sued to recover $90,627.89 paid under protest to the Comptroller of Public Accounts pursuant to the requirements of article 20A.33 of the Texas Insurance Code. Id. at 825. That statute provided as followed:
(a) To defray the expense of carrying out the provisions of this Act, there shall be annually assessed and collected by the State of Texas, through the State Board of Insurance, from each corporation operating under this Act, in addition to all other taxes now imposed, or which may hereafter be imposed by law, a tax of one percent of all revenues received by such corporation in return for issuance of health maintenance certificates or contracts in this state, according to the reports made to the State Board of Insurance as required by law. Said taxes, when collected, shall be placed in a separate fund with the State Treasurer which shall be kept separate and apart from other funds and money in his hands, and shall be known as the Health Maintenance Organization Fund, said fund to be expended during the current and succeeding years, or so much thereof as may be necessary, in carrying out such provisions. Such expenditures shall not exceed in the aggregate the sum assessed and collected from such corporations; and should there be an unexpended balance at the end of any year, the State Board of Insurance shall reduce the assessment for the succeeding year so that the amount produced and paid into the State Treasury together with said unexpended balance in the treasury will be sufficient to pay all expenses of carrying out the provisions of this Act, which funds shall be paid out and filed by a majority of the State Board of Insurance when the comptroller shall issue warrants therefor. Any amount remaining in said fund at the end of a year shall be carried over and expended in accordance with the provisions of this article during the subsequent year or years. Provided, that no expenditures shall be made from said fund except under the authority of the legislature as set forth in the general appropriations bill.
Id. at 825-26 (emphasis added). Prudential attacked the constitutionality of article 20A.33, claiming that the article contravened the Texas constitutional provision “requiring that all taxation, specifically including occupation taxes, be ‘equal and uniform.’ ” Id. at 826. The Commissioner responded that
the charges imposed by article 20A.33 do not contravene the ‘equal and uniform’ requirement of [the Texas Constitution] *170because they are not taxes at all, being only ‘fees’ imposed for regulatory purposes under the police power, and not the taxing power, of the sovereign, notwithstanding their denomination as ‘taxes.’
The Court found in favor of the Commissioner, determining that the charges were fees, not taxes:
We believe there are sufficient indicia of the legislative intent to warrant our holding that the charge authorized by subdivision (a) is intended primarily for regulation and not for revenue. While no single indicia standing alone compels the holding, the several do when considered together, viz.: the assignment of the revenue to a particular fund to be used solely for carrying out the regulatory purposes of the statute; the annual adjustments required of the Commissioner to produce only that amount of revenue needed to pay the cost of regulation... and authority for the charge is found among numerous other powers, requirements and conditions which are, without question, purely regulatory in nature, in a statute having the general purpose of regulation. Therefore, in accordance with the rule that the primary purpose of such a charge determines whether it is a tax or a regulatory fee, we hold it to be the latter in this case.
Id. at 829 (citations omitted).
In comparing the regulatory charge here with the assessment challenged in Prudential, we find similarly that the “ultimate use” of the revenue warrants our holding that the regulatory charge is not a tax. First, in Prudential, the fees, when collected, were placed is a segregated account called the Health Maintenance Organization Fund. Id. at 825. Here, G.S. 58-6-25(d) required that “proceeds of the charge levied . . . shall be credited to the [Insurance] Fund ...” and not the general fund of the state. Second, the funds in Prudential were to be used only to defray the cost of regulation. Id. The statute in the instant case, G.S. 58-6-25(a), stated that the charge “is levied on each insurance company ... to defray the cost to the Department of regulating the insurance industry ...” and (d) stated that the proceeds “shall be used only to pay the expenses of the Commissioner and the Department that are incurred in regulating the insurance industry . .. and the general administrative expenses of the State incident thereto.” Third, in Prudential, annual adjustments were required of the Commissioner to assure that the fee produced *171only the amount necessary to pay the cost of regulation. Id. at 829. Here, G.S. 58-6-25(b) requires similar adjustments, stating that the rate charged “may not exceed the rate necessary to generate funds sufficient to defray the estimated cost of the operations of the Department for each upcoming fiscal year.” Accordingly, we hold that the “ultimate use” of the insurance regulatory charge is regulation and the charge is not a tax.
Plaintiffs alternatively argue that even if the surcharge was not a tax, its exclusion from the retaliatory tax computation was still unconstitutional. Plaintiffs argue that aggregation of all tax and non-tax levies is the only constitutionally permissible avenue to equalization. Defendants respond that plaintiffs have not satisfied their burden of establishing the unconstitutionality of G.S. 105-228.8, arguing that “[t]here is nothing invalid or suspect about the decision of the legislature to require ... a comparison of only premium taxes paid by a foreign insurer and a domestic insurer for retaliatory purposes.” Defendants contend that non-tax charges are dealt with in G.S. 58-16-25. Accordingly, defendants maintain that G.S. 105-228.8 is not unconstitutional and summary judgment should be affirmed.
We hold that the plaintiffs have not met their burden of establishing the unconstitutionality of G.S. 105-228.8. We note that “insurance commissioners in some states consider only the items of tax on premium income and fees paid and disregard other burdens because of the practical difficulties involved in computing and comparing the varying exactions.” Republic Ins. Co. v. Commissioner of Taxation, 272 Minn. 325, 331, 138 N.W.2d 776, 780 (1965) (citing 39 Notre Dame Lawyer 243). Accordingly, we hold that it was not constitutionally invalid for the statute to require a comparison of only premium taxes paid by a foreign insurer for retaliatory purposes.
In sum, because the “ultimate use” of the regulatory charge is regulation, we hold that it was not a tax. Further, the exclusion of the charge in the computation of plaintiffs retaliatory premium tax liability was not unconstitutional. The order of the trial court is affirmed.
