General Dynamics Corp. v. Sharp

KIDD, Justice. General Dynamics Corporation appeals from a summary judgment granted to appel-lees 1 (collectively the “Comptroller”) in a tax-protest suit. See Tex.Tax Code Ann. §§ 112.051-112.060 (West 1992 & Supp.1996). Primarily at issue is whether the earned surplus portion of the amended Texas franchise tax is unconstitutionally retroactive. General Dynamics also contends that Texas’ single-factor method of apportioning its Texas franchise tax base violates the United States and Texas Constitutions. We will affirm the trial court’s judgment. THE CONTROVERSY 1. The Franchise Tax Act a. The Franchise Tax Base In 1905, the Texas Legislature enacted the Franchise Tax Act. Acts of 1905,29th Leg., ch. 19, p. 21, § 1. The franchise tax is levied annually on corporations that are incorporated in Texas or that conduct business in Texas, for the privilege of doing business in this State. Tex.Tax Code Ann. § 171.001 (West 1992 & Supp.1996); United North & South Dev. Co. v. Heath, 78 S.W.2d 650, 652 (Tex.Civ.App.-Austin 1934, writ ref d). The amount of franchise tax levied should approximate the value of this privilege. Sterling Oil & Ref. Corp. v. Isbell, 202 S.W.2d 300, 302 (Tex.Civ.App.-Austin 1947, no writ). “The formula used in the franchise tax is the valuation of the privilege granted by the Legislature.” General Dynamics Corp. v. Bullock, 547 S.W.2d 255, 258 (Tex.1976), cert. denied, 434 U.S. 1009, 98 S.Ct. 717, 54 L.Ed.2d 751 (1978). However, devising a formula that accurately assesses the value of each corporation’s privilege has not been a simple task. Prior to 1992, the franchise tax was based solely on a corporation’s taxable capital. A 1991 amendment to the franchise tax changed the tax base to the higher of taxable capital or earned surplus. 2 Tex.Tax Code Ann. § 171.002 (West 1992). Because the franchise tax was based solely on taxable capital prior to the amendment, capital-intensive industries bore the brunt of the tax, even in unprofitable years. On the other hand, service industries, even those generating large profits, did not pay as much, unless they were also capital intensive. The 1991 amendment to the franchise tax reapportioned the tax base. b. Apportioning the Tax Base The portion of a multi-state corporation’s taxable capital and earned surplus subject to the Texas franchise tax is calculated by using a single-factor, gross-receipts apportionment formula (“the Texas formula”). Tex.Tax Code Ann. §§ 171.103, 171.1031, 171.105, 171.1051 (West 1992 & Supp.1996). Gross receipts are generated from business and investment activities, such as selling goods and services, receiving dividends and interest, and realizing capital gains. Id. A corporation’s gross receipts generated in Texas are divided by the corporation’s total worldwide gross receipts to arrive at a fraction representing the corporation’s percentage of business in Texas. This percentage is then multiplied by the total tax base to calculate the amount of tax base apportionable to Tex *864 as. Tex.Tax Code Ann. § 171.106 (West 1992). The apportioned tax base is then multiplied by the tax rate to determine a corporation’s Texas franchise tax liability. See Tex.Tax Code Ann. §§ 171.002, 171.006, 171.110 (West 1992 & Supp.1996). From 1969 to 1988 Texas allowed corporations to use either the single-factor method of apportionment or a multiple-factor test. See Act of Sept. 6, 1969, 61st Leg., 2d C.S., eh. 1, art. 7, § 1, 1969 Tex.Gen.Laws 95, 96 repealed by Act of March 1, 1989, 71st Leg., R.S., § 2,1989 Tex.Gen.Laws 200. The multiple-factor test was repealed in 1989. Id. Now, the single-factor method of apportioning a corporation’s tax liability is the only method allowed by law in Texas. Tex.Tax Code Ann. § 171.106 (West 1992). 2. Factual Background General Dynamics’ situation in- this appeal is somewhat unique. In 1984, General Dynamics entered into a contract with the United States military to manufacture 720 F-16 fighter jets. Over a period of seven years, from 1984 to 1991, General Dynamics manufactured the F-16s and periodically delivered the jets to a military base in Texas. 3 Periodically, the government paid General Dynamics for the F-16s as the contract progressed. Thus, General Dynamics received profits each year from the manufacture and sale of the F-16s. In total, General Dynamics was paid approximately $974 million in profit from the contract. For federal income tax purposes, however, General Dynamics chose to utilize the “completed contract” method of reporting its profit. See Internal Revenue Code § 451 (26 U.S.C. § 451 (1994)). Under the “completed contract” method, a taxpayer realizes income for tax purposes in the year in which the contract was completed, in this case 1991. Id. Thus, for federal income tax purposes, General Dynamics realized all of the income earned over the life of the contract in 1991. In 1991, the Texas Legislature amended the Franchise Tax Act to add earned surplus as a method of calculating a corporation’s tax liability. Tex.Tax Code Ann. §§ 171.002, 171.110 (West 1992 & Supp.1996). The amendment became effective on January 1, 1992, and added a corporation’s earned surplus for the preceding year as an alternative tax base. 4 The earned surplus portion of the franchise tax relies primarily on net income as calculated for federal income tax purposes. See Tex.Tax Code Ann. § 171.110(a)(1) (West 1992 & Supp.1996). Thus, General Dynamics owed franchise tax on the full $974 million realized in 1991 for federal income tax purposes. 5 As a result, General Dynamics paid $33,-872,003 of its franchise tax under protest. See Tex.Tax Code Ann. §§ 112.051-112.060 (West 1992 & Supp.1996). General Dynamics filed suit against the Comptroller in an effort to recoup the protested franchise tax. The district court granted the Comptroller’s motion for summary judgment, and General Dynamics appeals to this Court. 3. The Parties’ Contentions General Dynamics’ primary contention is that the earned surplus portion of the franchise tax violates the Retroactivity Provision of the Texas Constitution. See Tex. Const, art. I, § 16. General Dynamics argues that the earned surplus portion of the franchise tax is actually a new “corporate income tax” and not merely a modification of an old tax. Because the amendment affected transactions or considerations from earlier years, General Dynamics argues that the amendment retroactively impairs its vested rights. Essentially, General Dynamics argues that, because it reasonably relied on the franchise tax as it existed in 1984 when deciding to opt for the “completed contract” method of as *865 sessing federal income taxes, the 1991 franchise tax amendment impaired its vested right in the continuation of the pre-1992 franchise tax scheme. The Comptroller argues that the franchise tax is not unconstitutionally retroactive. The Comptroller contends that because General Dynamics’ franchise taxes were not levied before the effective date of the amendment, the amendment did not operate retroactively. The Comptroller urges that the use of the previous year’s earned surplus as a measure of the franchise tax does not make the amendment retroactive. The secondary issue in this appeal concerns Texas’ method of apportioning its franchise tax base for multi-state corporations. Most states apportion their share of a corporation’s tax base by using a percentage generated by a three-factor formula equally weighing the percentage of property, payroll, and sales in the taxing state. Texas, however, uses a single-factor apportionment formula based solely on sales. Therefore, the Texas formula apportions a percentage of the tax base equal to the percentage of the corporation’s sales in Texas. In General Dynamics’ situation, Texas’ use of the single factor method yielded approximately $11 million more in Texas franchise tax owed. In other words, General Dynamics would owe approximately $11 million less in Texas franchise tax if Texas had used the three-factor apportionment formula. General Dynamics argues that this disparity is excessive and unfair and, therefore, the Texas formula violates the Commerce and Due Process Clauses of the United States Constitution and the Due Course of Law Provision of the Texas Constitution. The Comptroller responds that states are given wide latitude to develop apportionment formulas for state excise taxes and that the use of a single-factor formula should be upheld unless its use leads to a grossly excessive disparity in comparison with the three-factor formula. The Comptroller urges that the apportionment disparity in this ease is not sufficiently high to make the Texas formula unconstitutional. DISCUSSION “[W]e begin with a presumption of validity. It is to be presumed that the Legislature has not acted unreasonably or arbitrarily; and a mere difference of opinion, where reasonable minds could differ, is not a sufficient legal basis for striking down legislation....” Texas Workers’ Compensation Comm’n v. Garcia, 893 S.W.2d 504, 520 (Tex.1995); see also Prudential Health Care Plan, Inc. v. Commissioner of Ins., 626 S.W.2d 822, 827 (Tex.App.-Austin 1981, writ refd n.r.e.). If a legislative scheme or design can be justified under any possible state of facts, we will assume the existence of those facts. Garcia, 893 S.W.2d at 520; Massachusetts Indem. & Life Ins. Co. v. Texas State Bd. of Ins., 685 S.W.2d 104, 109 (Tex.App.-Austin 1985, no writ). When a statute is challenged as retroactive, we presume that it is meant to operate prospectively unless it explicitly states that it is retroactive. Code Construction Act, Tex.Gov’t Code Ann. § 311.022 (West 1988). 1. Retroactivity In its first two points of error, General Dynamics contends that the amendment to the franchise tax was unconstitutionally retroactive. On August 13, 1991, the Legislature passed the law that added earned surplus to the tax base of the franchise tax. Acts of 1991, 72nd Leg., 1st C.S., ch. 5, § 8.03, 1991 Tex.Gen.Laws 134, 152 (House Bill 11, effective January 1,1992). The effective date for House Bill 11 was January 1, 1992, and it applied to tax reports due on or after that date. Id. Corporations were not required to use the earned surplus method of calculating tax liability for reports due before the act’s effective date. Id. However, corporations were required to use their 1991 income to assess the amount of franchise tax owed for the privilege of doing business in Texas for the calendar year 1992. See Tex. Tax Code Ann. §§ 171.002, 171.110 (West 1992 & Supp.1996). In General Dynamics’ case, its 1991 income was actually accumulated over a seven-year period; however, because it chose to report the entire profit in 1991 for federal income tax purposes, that income was used to calculate earned surplus for General Dynamics’ 1992 franchise tax. *866 Id.; Internal Revenue Code § 451 (26 U.S.C. § 451 (1994)). Article I, section 16 of the Texas Constitution provides: “No bill of attainder, ex post facto law, retroactive law, or any law impairing the obligation of contracts shall be made.” Tex. Const. art. I, § 16. Retroactive laws are unconstitutional only if they impair vested rights. State v. Project Principle, Inc., 724 S.W.2d 387, 390 (Tex.1987); Deacon v. City of Euless, 405 S.W.2d 59, 62 (Tex.1966); Durish v. Channelview Bank, 809 S.W.2d 273, 278 (Tex.App.-Austin 1991, writ denied); 1 George D. Braden et al., The Constitution of the State of Texas: An Annotated and Comparative Analysis 58-62 (1977). General Dynamics argues that the earned surplus portion of the franchise tax is unconstitutionally retroactive because it imposed a new “corporate income tax” that operated on income earned in the prior calendar year. Therefore, General Dynamics argues that the new “corporate income tax” destroyed or impaired its vested rights because it “ereate[d] a new obligation, imposefd] a new duty, or attach[ed] a new disability, in respect to transactions or considerations already past .... ” Cardenas v. State, 683 S.W.2d 128, 131 (Tex.App.-San Antonio 1984, no writ). We reject General Dynamics’ argument because the amendment to the franchise tax operated prospectively, not retroactively. It is important to note the difference between a direct tax on property and the franchise tax. A direct tax on property is paid simply because the taxpayer owns the property at a given time. The franchise tax, however, is an excise tax levied as payment for the privilege of doing business during the year in which the tax is levied. American Home Assurance v. Texas Dep’t of Ins., 907 S.W.2d 90, 93 (Tex.App.-Austin 1995, writ requested); Sterling Oil, 202 S.W.2d at 302. The franchise tax is therefore prospective because the tax levied beginning January of a given calendar year pays for the privilege of doing business through December of that calendar year. As long as a tax is levied only after its effective date and is levied at least in part for the privilege of doing business during the current year, then it is not a retroactive tax. See American Home Assurance, 907 S.W.2d at 93; Houston Oil Co. v. Lawson, 175 S.W.2d 716, 722 (Tex.Civ.App.—Galveston 1943, writ ref d). General Dynamics argues that the tax is nevertheless retroactive because it uses facts from the prior calendar year, namely net worth and earned surplus, to measure the value of the privilege for which the franchise tax is paid. We disagree. “A statute is not retroactive merely because it draws upon antecedent facts for its operation.” Lewis v. Fidelity & Deposit Co., 292 U.S. 559, 571, 54 S.Ct. 848, 853, 78 L.Ed. 1425 (1934) (quoted in American Home Assurance, 907 S.W.2d at 93). A statute is retroactive only if it operates before its effective date. See State v. Galveston, Harrisburg, & San Antonio Ry., 100 Tex. 153, 97 S.W. 71, 78 (1906), rev’d on other grounds, 210 U.S. 217, 28 S.Ct. 638, 52 L.Ed. 1031 (1908); De Cordova v. City of Galveston, 4 Tex. 470, 479 (1849). The franchise tax operates only when it is levied for the privilege of doing business; it does not operate in the preceding year used to measure the value of the privilege. See Galveston, Harrisburg, & San Antonio Ry., 97 S.W. at 75; Coffee v. Castleberry, 258 S.W. 889 (Tex.Civ.App.—Amarillo 1924), referred and affirmed, 272 S.W. 767, 768 (Tex.Comm’n App.1925, judgm’t adopted). Therefore, the fact that the value of the privilege is measured by the financial circumstances of the taxpayer in a prior calendar year does not make the taxing statute retroactive. See Galveston, Harrisburg, & San Antonio Ry., 97 S.W. at 75, 79. The franchise tax amendment at issue in this appeal became effective January 1, 1992. It is not disputed that the tax was levied only after that date. Accordingly, we hold that the franchise tax amendment does not violate the Texas Constitution because it operates prospectively, not retroactively. However, even if the amendment were construed to operate retroactively, we would still hold that it does not violate the constitution. A retroactive law only violates the constitution if it also impairs vested rights. Project Principle, 724 S.W.2d at 390; *867 Deacon, 405 S.W.2d at 62; Durish, 809 S.W.2d at 278. General Dynamics argues-that its vested rights have been impaired because the amendment to the franchise tax violated the expectations upon which it relied in formulating its business plan for 1991 and its decision to use the “completed contract” method of accounting to realize all income in 1991. We disagree. General Dynamics’ vested rights have not been impaired because no Texas taxpayer has a vested right in the continuation of a particular measurement method for the franchise tax. See Smith v. Davis, 426 S.W.2d 827, 834 (Tex.1968). General Dynamics relies upon Ohio authority to argue that its vested rights have been impaired by the franchise tax amendment. See Lakengren v. Kosydar, 44 Ohio St.2d 199, 339 N.E.2d 814 (1975). In Lakengren, the Ohio Supreme Court held that an amendment to Ohio’s franchise tax was unconstitutionally retroactive under similar circumstances. Id. 339 N.E.2d at 815-17. We reject General Dynamics’ reliance on Ohio law because Texas courts have decided the issue differently. In Lakengren, the Ohio Supreme Court noted that an Ohio taxpayer had a vested right in the continuation of a particular tax scheme as long as the taxpayer reasonably relied on the tax scheme. See id., 339 N.E.2d at 815, 817 (“The prohibition against retroactive laws ... is a protection for the individual who is assured that he may rely upon the law as it is written and not be subject later to new obligations thereby.” (emphasis added)). The Texas Supreme Court has specifically rejected the rationale advanced by General Dynamics: “A property owner has no vested right to have his property assessed by any particular method or system...” Davis, 426 S.W.2d at 834. Because the franchise tax amendment at issue is not retroactive and does not impair General Dynamics’ vested rights, we hold that it is not unconstitutionally retroactive and overrule General Dynamics’ first and second points of error. 2. Apportionment In its third point of error, General Dynamics challenges the Texas formula used to apportion the franchise tax base. A multi-state corporation such as General Dynamics has its tax base apportioned among the various states in which it does business. States use different formulas to approximate the amount of the tax base attributable to each taxing state. Texas uses a single-factor formula based on gross receipts; in other words, Texas apportions a percentage of the corporation’s total tax base equal to the corporation’s Texas gross receipts divided by the corporation’s total gross receipts. See Tex.Tax Code Ann. §§ 171.002, 171.006, 171.110 (West 1992 & Supp.1996). Almost every other state that charges corporations for the privilege of doing business uses a three-factor method of apportionment based on payroll, property, and gross receipts. 6 *868 General Dynamics complains that its Texas franchise tax burden for the period at issue was approximately $11 million higher under the Texas formula than it would have been if Texas had used the three-factor formula. Because General Dynamics has relatively more gross receipts in Texas but relatively less property and payroll in Texas than in other states, the three-factor formula would have reduced the percentage of its tax base apportioned to Texas. General Dynamics blames the Texas formula for this disparity and argues that, as applied in this appeal, the Texas formula is unfair and violates the Commerce 7 and Due Process Clauses 8 of the United States Constitution and the Due Course of Law Provision 9 of the Texas Constitution. General Dynamics shoulders a heavy burden in challenging the constitutionality of the Texas formula as applied in this appeal. The United States Supreme Court has repeatedly held that states are entitled to great latitude in devising formulas to apportion their tax bases. Moorman Mfg. Co. v. Bair, 437 U.S. 267, 274, 98 S.Ct. 2840, 2345, 57 L.Ed.2d 197 (1978). In Moorman, the Court sustained the constitutional validity of an Iowa single-factor formula identical to the Texas formula at issue in this appeal. Id. at 270, 281, 98 S.Ct. at 2342, 2348. The Court noted that a single-factor formula is presumptively valid. Id. at 273, 98 S.Ct. at 2344. Even though a majority of states use the three-factor apportionment formula, a healthy respect for federalism dictates that the minority of states using single-factor formulas cannot be blamed for any resulting disparities. Id. at 276-77, 98 S.Ct. at 2346. General Dynamics contends that the Texas formula creates an unfair disparity and is therefore unconstitutional because the formula increased its franchise tax liability by almost $11 million. However, the validity of an apportionment scheme does not depend on the absolute amount of tax at issue nor even on the fairness of the formula as applied. General Dynamics persuasively argues that the Texas formula may be unfair in some instances. 10 However, even assuming that the Texas formula may operate with some degree of unfairness, a decision to change the formula properly lies within the province of the Texas Legislature. We do not sit to devise wise tax policy for this State; our inquiry ends once we determine that the formula is constitutional. See Isbell v. Gulf Union Oil Co., 147 Tex. 6, 209 S.W.2d 762, 765 (1948); Aerospace Optimist Club v. Texas, 886 S.W.2d 556, 559 (Tex.App.-Austin 1994, no writ). Whatever the faults of the Texas formula, we cannot say that it is unconstitutional. To show that an apportionment method is unconstitutional, a taxpayer must prove by “‘clear and cogent evidence’ that the income attributed to the State is ‘out of all appropriate proportion to the business transacted ... in that State,’ or has led to a ‘grossly distorted result.’” Moorman, 437 U.S. at 274, 98 S.Ct. at 2345 (quoting Hans Rees’ Sons v. North Carolina, 283 U.S. 123, 135, 51 S.Ct. 385, 389, 75 L.Ed. 879 (1931) and Norfolk & Western Ry. v. Missouri State Tax Comm’n, 390 U.S. 317, 326, 88 S.Ct. 995, 1001, 19 L.Ed.2d 1201 (1968)). The disparity is measured by the difference between the percentage of the tax base apportioned under *869 the challenged formula and a hypothetical percentage apportioned under the formula urged by the taxpayer. As indicated by the Supreme Court precedents discussed below, even a significant disparity does not suffice to find a challenged formula unconstitutional. The Court has only twice held the application of a single-factor formula to be unconstitutional. See Hans Rees’ Sms, 283 U.S. at 132-36, 51 S.Ct. at 388-89; Norfolk & Western Ry., 390 U.S. at 326-29, 88 S.Ct. at 1001-03. In Hans Rees’ Sons, the difference between the taxpayer and statutory formulas was 250 percent. 11 See Hans Rees’ Sons, 283 U.S. at 132-36, 51 S.Ct. at 388-89. In Norfolk & Western Ry., the difference between the two formulas was 162-205%. Norfolk & Western Ry., 390 U.S. at 326-29, 88 S.Ct. at 1001-03. In this appeal, the difference in the apportionment of General Dynamics’ Texas tax base under the two formulas is 28%. The 28% difference in this appeal is simply insufficient to show a grossly distorted result that is out of all proportion with the percentage actually apportioned. Not only is the disparity an order of magnitude smaller than in the two challenges the Supreme Court has sustained, but the Court has also upheld percentage disparities ranging between 14-93%. 12 See Container Corp., 463 U.S. at 174 n. 11, 175 n. 12, 184, 103 S.Ct. at 2944 n. 11, 2945 n. 12, 2950 (14%); Moorman, 437 U.S. at 271, 98 S.Ct. at 2343 (25-40%); Underwood Typewriter v. Chamberlain, 254 U.S. 113, 119-120, 41 S.Ct. 45, 46, 65 L.Ed. 165 (1920) (93%). As a matter of law, the disparity in this appeal is too small to sustain a constitutional challenge to the Texas formula. See Container Corp., 463 U.S. at 184, 103 S.Ct. at 2950 (“[the 14% disparity is] a far cry from the more than 250% difference which led us to strike down the state tax in Hans Rees’ Sons, Inc., and a figure certainly within the substantial margin of error inherent in any method of attributing income among the components of a unitary business.”) (citations omitted). General Dynamics, relying on Justice Powell’s dissenting opinion in Moorman, also argues that a single-factor method of apportionment discriminates against interstate commerce. See Moorman, 437 U.S. at 283, 98 S.Ct. at 2349 (Powell, J., dissenting). General Dynamics reasons that an out-of-state corporation is likely to have substantial out-of-state property and payroll that would serve to dilute the overall apportionment factor based solely on sales if a multiple-factor method was used. We reject this argument. First, we decline to follow a dissenting opinion over well-settled Supreme Court precedent. Second, we agree with the majority opinion in Moorman that the single-factor apportionment formula treats all corporations “with an even hand.” See Moorman, 437 U.S. at 277 n. 12, 98 S.Ct. at 2346 n. 12. The Texas formula is geographically neutral because it uses the single factor without regard to the state of incorporation. Though the Texas formula may operate more favorably for corporations with relatively lower sales in Texas, the rule applies in the same fashion to Texas and foreign corporations alike. The Texas single-factor formula for apportionment is not unconstitutional as applied to General Dynamics. General Dynamics has shown that its tax burden would have been lower if Texas had used a three-factor apportionment formula. However, the increase in General Dynamics’ tax base apportioned to Texas is insufficient as a matter of law to demonstrate that the Texas formula as applied to it is unconstitutional. We therefore overrule General Dynamics’ third point of error. *870 CONCLUSION Having overruled each of appellant’s points of error, we affirm the district court’s judgment. POWERS, J., not participating. Footnotes [1] Appellees are John Sharp, Comptroller of Public Accounts of the State of Texas; Martha Whitehead, Successor in Office to Kay Bailey Hutchi-son, Treasurer of the State of Texas; and Dan Morales, Attorney General of the State of Texas. [2] Corporations' taxable capital consists of stated capital and surplus. Tex.Tax Code Ann. § 171.101(a)(1) (West 1992). Stated capital is defined by reference to the Texas Business Corporation Act. See Tex.Bus.Corp.Act, art. 1.02(18) (West Supp.1996). The Franchise Tax Act defines surplus as net assets minus stated capital. Tex.Tax Code Ann. § 171.109(a)(1) (West 1992). Net assets are total assets minus total debts. Tex.Tax Code Ann. § 171.109(a)(2) (West 1992). Earned surplus is reportable federal net income, less certain foreign source income, plus officer and director compensation. Tex.Tax Code Ann. § 171.110(a)(1) (West 1992 & Supp.1996). [3] General Dynamics delivered 108 aircraft in 1987, 178 in 1988, 158 in 1989, 200 in 1990, and 76 in 1991 for a total of 720 F-16s. [4] The reason for using past income to measure the privilege of doing business in a current year is because past or accumulated wealth is the financial starting point for the current year’s business.

[7] The Commerce Clause states that Congress shall have the power “[t]o regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes.” U.S. Const. art. I, § 8, cl. 3. [8] The Due Process Clause provides that no person shall be deprived "of life, liberty or property, without due process of law.” U.S. Const. amends. V and XIV, § 1. [9] The Due Course of Law Provision provides: “No citizen of this State shall be deprived of life, liberty, or property, or privileges and immunities, or in any manner disfranchised, except by the due course of the law of the land.” Tex. Const, art. I, § 19. [10] General Dynamics argues that the three-factor formula more appropriately values the privilege to do business because companies with relatively higher payroll and property in Texas use substantial state services and therefore should have a higher percentage of their tax base apportioned to Texas. Conversely, corporations such as General Dynamics that have relatively higher sales in Texas would have a lower percentage of their tax base apportioned to Texas. [11] Appellant has calculated the disparity in Hans Rees' Sons as 469 percent. The Supreme Court, however, calculated it at 250 percent in a subsequent opinion. See Container Corp. of Am. v. Franchise Tax Bd., 463 U.S. 159, 184, 103 S.Ct. 2933, 2950, 77 L.Ed.2d 545 (1983). We have used the Supreme Court's number, but we note that it makes no difference in this appeal. [12] The Court has upheld formulas producing greater percentage disparities in situations where a lower dollar amount was involved, making the percentage disparity far less meaningful.
