ARK. J 207 R. L. QUALLS, Director DEPARTMENT OF FINANCE AND ADMINISTRATION, State of Arkansas v. MONTGOMERY WARD & CO., INC. 78-35 585 S.W. 2d 18 Opinion delivered July 2, 1979 [Rehearing denied September 4, 1979.]

1. TAXATION - INTEREST ON LOANS OF MULTI-STATE CORPORATIONS TO RELATED CORPORATIONS CONSTITUTES BUSINESS INCOME - AP-PORTIONMENT OF BUSINESS INCOME AMONG THE SEVERAL STATES FOR INCOME TAX PURPOSES PROPER. - Income from interest on 10? ns made in the regular course of the business of a multi-state corporation doing business in Arkansas from its excess work­ing capital to its subsidiary, affiliate, parent and related cor­porations is business income and should be apportioned, for the purpose of taxation, among all the states in which the corpora­tion does business, pursuant to Ark. Stat. Ann. § 84-2063 (Supp. 1977). 2. TAXATION - UNIFORM DIVISION OF INCOME FOR TAX PURPOSES ACT - PURPOSE OF ACT TO BRING UNIFORMITY IN TAXING MULTI-STATE CORPORATIONS. - The Uniform Division of Income for Tax Pur­poses Act (UDITPA) [Act 413, Ark. Acts of 1961, Ark. Stat. Ann. § 84-2055, el seq. (Supp. 1977)] was adopted to bring about uniformity among the states in taxing the income of multi-state corporations, and to avoid potential duplication of taxing the same income, by providing for a fair means of assign­ing taxable income among the states. 3. TAXATION - "BUSINESS INCOME" - DEFINITION CONTAINED IN UDITPA. "Business income" is defined by Ark. Stat. Ann. § 84-2055 (a) (Supp. 1977) as income arising from transactions and activity in the regular course of the taxpayer's trade or business and includes income from tangible and intangible property if the acquisition, management, and disposition of the property constitute integral parts of the taxpayer's regular trade or business operations. 4. TAXATION - "NON-BUSINESS INCOME" UNDER UDITPA WHAT CONSTITUTES. - "Non-business income" is all income other than business income as defined by Ark. Stat. Ann. § 84-2055 (a) (Supp. 1977). [Ark. Stat. Ann. § 80-2055 (3) (Supp. 1977).1 5. TAXATION - A SSIGNING INCOME OF MULTI-STATE CORPORATION TO VARIOUS STATES UNDER UDITPA USE OF THREE-FACTOR AP-PORTIONMENT FORMULA. - The method of assigning income of a multi-state corporation among the various states under UDITPA involves a three-factor apportionment formula requir­ing a determination of three ratios, based upon property,

208 QUALLS, DIRECTOR V. MONTGOMERY WARD & CO. 1266 payroll and sales, the ratios being determined by dividing the particular factor, as it relates to Arkansas, by the corporation's total for that factor; and when each of the factors is determined they are averaged by adding them and dividing by three, the taxpayer's net business income being then multiplied by the resulting fraction, which results in the amount of the cor-poration's income which is subject to income tax in Arkansas. 6. TAXATION NON-BUSINESS INCOME ALLOCATION TO A PAR-TICULAR STATE UNDER UDITPA. "Non-business income" is not apportioned but is allocated to 'a certain state under the provisions of UDITPA.

7. TAXATION INTEREST ON LOANS BY MULTI-STATE CORPORATION TO RELATED CORPORATIONS PRODUCT OF TRANSACTIONS & AC-TIVITY IN REGULAR COURSE OF BUSINESS. Interest on loans and advances by a multi-state corporation doing business.in Arkan-sas, made to corporate relatives on a regular basis, is income from intangible property belonging to the corporation arising from transactions and activity in the regular course of business, and constitutes business income as defined in Ark. Stat. Ann. § 84-2055 (a) (Supp. 1977).

8. TAXATION TAXABLE TRANSACTIONS BY MULTI-STATE COR-PORATIONS MUST BE IN REGULAR COURSE OF TAXPAYER'S TRADE OR BUSINESS OPERATIONS. Under UDITPA, it is not required that transactions by a multi-state corporation be in the course of the corporation's regular trade, but it is only required that the transactions be in the "regular course of the taxpayer's trade or business operations."

9. TAXATION TAXATION OF "BUSINESS INCOME" USE OF IN-TEREST AS WORKING CAPITAL INFERS THAT IT IS BUSINESS INCOME. The acquisition, management and disposition of the working capital of a corporation, which includes interest on loans to the corporation's subsidiaries, constituted an integral part of the corporation's regular trade or business operation, and the use of the interest just as other working capital is used leads to the conclusion that it is business income.

10. CORPORATIONS LENDING MONEY TO RELATD CORPORATIONS CONSTITUTES ACTIVITY IN REGULAR COURSE OF BUSINESS COR-PORATION NEED NOT BE MONEY LENDER. Under the cir­cumstances prevailing, the regular and consistent lending of money by a corporation to its related corporations consists of transactions constituting an activity in the regular course of the corporation's business, and the fact that the corporation's regular trade or business operations did not include money lending is of no significance.

11. TAXATION 1963 AMENDMENT OF UDITPA EFFECT. Ark. Stat. Ann. § 84-2055 (a) (Supp. 1977) was amended by Act 529,

ARK.] QUALLS, DIRECTOR V. MONTGOMERY WARD & CO. 209 Ark. Acts of 1963 (which was repealed by Act 1024 of 1979, after the case at bar was submitted), whereby the scope of the term "business income" was extended where a corporation, domiciled in Arkansas, and owning 50% or more of the stock of a subsidiary, would be required to include all interest paid to it by that subsidiary as business income, to be apportioned among the states in which the parent corporation did business, if those states had a formula for apportionment of business income, and only if the parent- having its commercial domicile in Arkansas owned less than one-half of the stock of the subsidiary would the interest be allocated to Arkansas as non-business income; however, the sentences added by the 1963 act were not con­trolling when the interest arose from transactions and activities in the regular course of the parent's business and was income from money, the acquisition, management and disposition of which constituted an integral part of the parent's regular business operations, unless the interest was paid by a corpora­tion in which the recipient owned less than one-half of the stock. 12. CORPORATIONS - LOANS & ADVANCES BY CORPORATION TO COR-PORATE RELATIVES - PART OF REGULAR BUSINESS OPERATIONS. Loans and advances by a corporation to its corporate relatives are a part of the corporation's regular business operations where it is the apparent purpose and intent of the corporation in so doing to assure their financial stability and continued opera-tion, which would be beneficial to the corporation's regular business; their expansion is dependent, in most instances, upon the corporation's approval; and management and overhead ex­penses are paid to the corporation by its corporate relatives in relation to these loans. 13. TAXATION - INCOME OF CORPORATION FROM INTEREST ON LOANS TO CORPORATE RELATIVES - FACT THAT INCOME IS SMALL IM-MATERIAL. - The fact that income from interest on loans made by a corporation to its corporate relatives may be small in proportion to its total income does not mean that the trans­actions and activities giving rise to it were not in the regular course of the corporation's business or the money lent not ac-cumulated, managed or disposed of as an integral part of its regular business operations. 14. TAXATION - RELATED CORPORATIONS WHICH ARE NOT REQUIRED TO FILE COMBINED TAX RETURNS - NOT INDICATIVE THAT INCOME ARISING FROM DIVIDENDS OR INTEREST IS NOT INCOME ARISING FROM TRANSACTIONS IN REGULAR COURSE OF BUSINESS. - Simply because the management, operation and activity of a corpora­tion in which the taxpayer owns stock is not so closely con­nected with the management, operation and activities of the taxpayer to warrant a combined tax return, does not ipso facto

210 QUALLS, DIRECTOR V. MONTGOMERY WARD & CO. 1266 mean that the dividends the taxpayer receives from that stock (or income it receives from interest on loans) cannot be income arising from transactions and activities in the regular course of the taxpayer's trade or business, or that it does not constitute integral or necessary parts of the taxpayer's trade or business operations.

15. STATUTES DECISION BASED ON CONSTRUCTION OF TAXATION STATUTES, NOT ON REGULATIONS REGULATIONS REFLECT REVENUE DEPARTMENT'S VIEW OF PROPER APPLICATION. The decision in the case at bar is based upon the Supreme Court's construction of the applicable statutory provisions and not upon the regulations of the revenue department, the only significance of these regulations being that they reflect the revenue department's view of the proper application of the statute-at the time the assessment was made against the appellee corporation. 16. TAXATION UDITPA, AS ADOPTED IN ARKANSAS PRESUMP-TIVELY CONSTITUTIONAL. The Uniform Division of Income for Tax Purposes Act (UDITPA), as adopted in Arkan-sas, [Act 413, Ark. Acts of 1961, Ark. Stat. Ann. § 84-2055 el seq. (Supp. 1977)] is presumptively constitutional and all doubt as to its validity must be resolved in favor of the act. 17. TAXATION CONSTITUTIONALITY OF CONCEPT OF FORMULARY AP-PORTIONMENT ESTABLISHED BURDEN ON TAXPAYER TO SHOW ARKANSAS FORMULA PLACES BURDEN ON INTERSTATE COMMERCi. The constitutionality of the concept of formulary apportion­ment under both the due process and commerce clauses is now well established, and the burden is upon the taxpayer to show that a formula such as that used in Arkansas places a burden on interstate commerce in a constitutional sense. 18. TAXATION FORMULA FOR APPORTIONMENT OF TAXES OF MULTI-STATE CORPORATION CLEAR & COGENT EVIDENCE REQUIRED TO PROVE UNCONSTITUTIONALITY. One who attacks a formula for the apportionment of taxes of a multi-state corporation among the various states where it does business must show by clear and cogent evidence that the use of the formula results in ex­traterritorial values being taxed and that it violates due process. 19. TAXATION IMPOSITION OF TAXES ON FOREIGN CORPORATIONS DOING BUSINESS IN STATE BASIS & PURPOSE. Taxes are im­posed on corporations doing business in a state as a pecuniary charge for the protection the state affords them in their operations within the state; and the provision of an orderly market in which the taxpayer may do business is a sufficient basis.

20. TAXATION LIMITATION ON STATE'S POWER TO TAX FOREIGN COR-PORATIONS WHAT CONSTITUTES. The limitation on a state's power to tax a foreign corporation is that the measure of the tax

ARK.] QUALLS, DIRECTOR V. MONTGOMERY WARD & CO. 211 must bear some reasonable relation to its doing business in the state, i.e., there must be some minimal connection between the activities and the taxing state. 21. CONSTITUTIONAL LAW - VIOLATION OF COMMERCE CLAUSE - WHAT CONSTITUTES. - A state may violate the commerce clause when it discriminates against interstate commerce by subject­ing it to the burden of multiple taxation to which local com­merce is not exposed. 22. TAXATION - STATE TAX STATUTES - CONSTITUTIONALITY UNDER DUE PROCESS & INTERSTATE COMMERCE CLAUSES. - A tax levied by a state may run afoul of the due process and interstate com­merce clauses, if it is not laid on property, business done, or transactions carried on within the state. 23. TAXATION - STATE APPORTIONMENT STATUTES - CON-STITUTIONAL WHERE TAXES LEVIED ONLY ON PROFITS EARNED WITHIN STATE. - A staie does not vfolate U.S. Const., Amend. 14, when its legislature, faced with the practical impossibility of allocating specifically the profits earned by a corporation engag­ed in interstate commerce through processes conducted within the borders of that state, adopts a method of apportionment that reaches, and was meant to reach, only the profits earned within the state. 24. TAXATION - TAX ON BOTH INTERSTATE & INTRASTATE INCOME OF CORPORATION - CONSTITUTIONAL WHERE FAIRLY APPORTIONED AMONG STATES. - The entire net income of a corporation generated by interstate, as well as intrastate, activities may be fairly apportioned among the states for tax purposes by a for­mula utilizing in-state aspects of interstate affairs without violating either the due process or commerce clauses of the United States Constitution. 25. TAXATION - NON-DISCRIMINATORY STATE TAXATION OF PROP-ERLY APPORTIONED NET INCOME FROM INTERSTATE OPERATIONS OF FOREIGN CORPORATIONS - CONSTITUTIONALITY. - Net in­come from the interstate operations of a foreign corporation may be subjected to state taxation, provided the levy is not dis­criminatory and is properly apportioned to local activities within the taxing state, forming sufficient nexus to support the same, without violating either the due process or commerce clauses of the United States Constitution. 26. TAXATION - STATE'S TAXATION OF FOREIGN CORPORATIONS - CONNECTION WITH TAXING STATE REQUIRED. - There must be some minimal connection between the business activities generating the income of a foreign corporation and the taxing state, the income attributed to the state for taxing purposes must be rationally related to values connected with the taxing state, and the mere fact that the demand of the tax exaction is

212 QUALLS, DIRECTOR U. MONTGOMERY WARD & CO. [266 contingent upon events brought to pass outside the state does not destroy the nexus between the tax and transactions within the state for which the tax is an exaction.

27. TAXATION - THREE-FACTOR FORMULA FOR TAXING MULTI-STATE FOREIGN CORPORATIONS - CONSTITUTIONALITY. - The three-factor formula or another quite similar adopted in other states for taxing multi-state foreign corporations has been held to be constitutional in that it does not violate either the due process clause or the commerce clause of the Constitution of the United States.

28. TAXATION - APPORTIONMENT FORMULA - EXACT MEASURE NOT REQUIRED TO MEET DUE PROCESS REQUIREMENTS. - It iS not necessary that a state demonstrate that an apportionment for­mula results in an exact measure in order to avoid trans­gression of the due process and commerce clauses of the United States Constitution, and the mere fact that application of the formula may result in some overlapping of measures of net in­come among states is not fatal. 29. TAXATION - VALIDITY OF STATE APPORTIONMENT FORMULA - ROUGH APPROXIMATION OF APPORTIONMENT SUFFICIENT. - In considering the validity of a statute's apportionment formula in the light of the prohibition against a state's burdening interstate commerce, the United States Supreme Court has recognized the practical impossibility of a state's achieving a perfect apportion­ment of expansive, complex, multi-state business activities, and finds a rough approximation, rather than precision, sufficient. 30. TAXATION - STATE TAX LAW ON MULTI-STATE CORPORATIONS - CLEAR PROOF THAT TAX IS LEVIED UPON INTERSTATE COMMERCE REQUIRED FOR NULLIFICATION. - Unless it iS demonstrated that an apportionment formula which includes consideration of in­terstate and out-of-state transactions in relation to the intrastate privilege of doing business produces a palpably dispropor­tionate result, making it patent that the tax is levied upon in­terstate commerce, a state's tax law will not be nullified.

31. TAXATION - INCOME FROM INTEREST AS PART OF WORKING CA PITAL OF MULTI-STATE CORPORATION - PORTION AT-TRIBUTABLE TO ARKANSAS TAXABLE UNDER THREE-FACTOR AP-PORTIONMENT FORMULA. - Where income earned in Arkansas went into the appellee corporation's working capital and, in the regular course of appellee's business, loans and advances to related corporations earned interest which also went into work­ing capital, a part of which was used to carry on operations in Arkansas, these facts provide the necessary nexus, not to justify taxation of the total amount of this interest income, but to justify taxing that portion attributable to Arkansas under the three-factor apportionment formula.

- ARK.] QUALLS, DIRECTOR v. MONTGOMERY WARD & CO. 213 Appeal from Pulaski Chancery Court, Third Division, Bruce Bullion, Chancellor; reversed Robert G. Brockmann, James R. Eads, Jr., Joseph V. Svoboda, Barry E. Coplin and Thomas Clark, Jr., by Jack East III, for appellant. William D. Dexter, Olympia, Wash., for amicus curiae (for appellant) Multistate Tax Commission.

Richard A. Williams and Eugene G; Sayre of Williams, Selig, Overbey & Sayre, for appellee. George W. Koch, Washington; D.C. for amicus curiae (for appellee) Committee on State Taxation of Council of State Chambers of Commerce. JOHN A. FOGLEMAN, Justice. This case involves the very complex problem of apportionment of income of a multi-state corporation for purposes of income taxation in the various states in which the corporation does business. Montgomery Ward & Company, Inc., is an Illinois corporation. Its cor­porate headquarters and principal place of business are in Chicago, Illinois. Its primary business is sale of a wide range of merchandise at retail outlets located in all but one of the states of the United States. It is qualified to do, and, during the years involved, did, business in Arkansas through retail stores, catalog stores, and catalog agency stores. It derives in­come from interest on loans made by it to its subsidiary, af-filiate, parent and related corporations. On its corporate in­come tax returns to the State of Arkansas for its fiscal years ending February 2, 1972, January 31, 1973, and January 30, 1974, Ward deducted this interest income from its nationwide income before computing income tax due the State of Arkansas pursuant to the apportionment proVision of the Arkansas version of the Uniform Division of Income for Tax Purposes Act [Ark. Stat. Ann. § 84-2055, et seq. (Supp. 1975 and 1977)]. After agents of the Arkansas Department of Finance and Administration had audited these returns, they disallowed this deduction of interest income and assessed an additional

214 QUALLS, DIRECTOR U. MONTGOMERY WARD & Co. (266 tax of $26,975.40, not all of which was attributable to this deduction. Ward protested and requested an administrative hearing, which was held before the Arkansas Revenue Department Hearing Board. On May 10, 1976, that board sustained the disallowance of this deduction, but reduced the assessment, because of the allowance of other protested items, to $17,148, which Ward paid under protest. Ward timely filed this suit for a refund in the Chancery Court of Pulaski County, where it was tried on April 5, 1977, and a decree entered on October 19, 1977. This appeal was taken from that decree. Ward has consistently taken the position that it correctly treated this interest as "non-business in-come," as defined by Ark. Stat. Ann. § 84-2055 (e) (Supp. 1977), and that it should be allocated to Illinois, the state in which its principal office is located, for purposes of taiation, pursuant to Ark. Stat. Ann. § 84-2061 (Supp. 1977). Appellant, and his predecessors in office, have, at all times, contended that this interest income, for the years in question, should, for the purpose of taxation, be apportioned among all the states in which Ward did business, pursuant to Ark. Stat. Ann. § 84-2063 (Supp. 1977). The chancery Court agreed with appellee and rendered its decree for refund of the tax paid under protest. We disagree with the chancery court and agree with appellant. In its complaint, Ward alleged that this interest was "non-business income," as defined by the statute, because it was not an integral part of its regular trade or business operations. In the alternative, Ward asserted that this section violated the due process and equal protection clauses of die Constitution of Arkansas and the Fourteenth Amendment to the Constitution of the United States and the commerce clause of the United States Constitution. The chancery court decided the case without reaching the constitutional questions. It was proper for that court to do this, -if it correctly held that the interest was "non-business income." Since the correctness of that holding is appellant's first point for rever-sal, we approach it first. The tax was assessed on the basis of a definition of business income now set out in Regulation IV.1(a) of the Arkansas Revenue Department, an agency of the Depart-

ARK.] QUALLS, DIRECTOR V. MONTGOMERY WARD & Co. 215 ment of Finance and Administration. Pertinent language of that regulation follows:

In essence, all income which arises from the conduct of trade or business operations of a taxpayer is business in-come. For purposes of administration of Article IV [of the Multistate Tax Compact], the income of the tax­payer is business income unless clearly classified as non-business income.

* * * *** Income of any type or class and from any source is business income if it arises from transactions and activi­ty occurring in the regular course of a trade or business. Accordingly, the critical element in determining whether income is "business income" or "nonbusiness income" is the identification of the transactions and ac­tivity which are the elements of a particular trade or business. In general all transactions and activities of the taxpayer which are dependent upon or contribute to the operations of the taxpayer's economic enterprise as a whole constitute the taxpayer's trade or business and will be transactions and activity arising in the regular course of, and will constitute integral parts of, a trade or business.

Regulation IV.7(3) also speaks on the subject, viz: Interest income is business income where the intangible with respect to which the interest was received arises out of or was created in the regular course of the taxpayer's trade or business operations or where the purpose for acquiring and holding the intangible is related to or in­cidental to such trade or business operations. Several examples illustrative of the application of interest in­come to be treated as business income under Regulation IV.7(3) follow the text of the regulation. None of them specifically cover the interest involved here, but they do in­clude interest on federal income tax refunds, interest on a judgment against a debtor, interest on a special account

216 QUALLS, DIRECTOR V. MONTGOMERY WARD & CO. (266 maintained to cover workmen's compensation, rain and storm damage, and machinery replacement, interest on tem­porary investment of funds intended for payment of federal, state and local taxes, interest on funds held pending redemp­tion of money orders and traveler's checks issued by the tax-payer, interest on working capital and extra cash invested in securities, and interest on the proceeds of sale of a subsidiary which are held in an interest-bearing account until utilized. Litigation related to income taxes is usually complex because of the necessity for tax laws to be drafted in language peculiar to that field of taxation, but broad enough to cover the declaration of legislative intent as to taxable income, deductions, and exemptions. In order to carry out the legislative intent, it is necessary for the General Assembly to adopt statutory definitions of terms used in an effort to minimize differences in interpretations of the legislative in­tent which would inevitably arise from efforts to apply the usual and ordinary meanings given the statutory words. In a uniform act definitions are, of course, intended to promote uniformity in the application of tax laws. Dealing with the equitable taxation of a multi-state cor-poration, enmeshed in a pattern of intercorporate and in­tracorporate dealings with parents, affiliates and sub-sidiaries, appears to have been a serious problem to the legislators and administrators and the problem of judicial in­terpretation of unfamiliar technical language applied to an unfamiliar field becomes the most perplexing of all statutory interpretations. When constitutional issues are involved, the matter is further complicated. An additional problem is the necessity for preserving and promoting uniformity of applica­tion of a uniform act in all the states adopting it. See Ark. Stat. Ann. § 84-2073 (Repl. 1977). There is virtually no dispute about the facts. The real question involved is one of statutory interpretation and the application of that interpretation to the facts. The basic ques­tion is whether interest earned on loans and advances by one' member of a complex corporate family to its corporate parent, its corporate siblings, and its corporate children, is

ARK.] QUALLS, DIRECTOR v. MONTGOMERY WARD & Co. 217 business or non-business income, as those terms are defined by statute. The basic statutory provision involved is a section of Act 413 of 1961, which as amended, is digested as Ark. Stat. Ann. § 84-2055 et seq. (Supp. 1977). The act is the adoption by Arkansas of the Uniform Division of Income for Tax Purposes Act, known as UDITPA. It appears to have been adopted as an effort to bring about uniformity among the states in taxing the income of multi-state corporations and to establish an equitable basis for taxation by avoiding potential duplication of taxing of the same income and by providing for a fair means of assigning taxable income among the states. The particular section is Ark. Stat. Ann. § 84-2055 (a), defining business income. Appellant contends that the interest in question is business income to Ward and that it should be ap­portioned among the states in which Ward does business, in the same manner as Ward's other business income. Ward contends, and the chancery court held, that this interest is not an integral part of its regular trade or business and, therefore, is non-business income taxable only in the State of Illinois. The answer requires us to interpret § 84-2055 (a) and apply it to the facts. The pertinent part of that section reads: "Business income" means income arising from transac­tions and activity in the regular course of the taxpayer's trade or business and includes income from tangible and intangible property if the acquisition, management, and disposition of the property constitute integral parts of the taxpayer's regular trade or business operations. *** Non-business income is all income other than business in­come as above defined. Ark. Stat. Ann. § 84-2055 (e) (Supp. 1977). The method of assigning income among the various states under UDITPA involves a three-factor apportionment formula. This formula involves a determination of three ratios, based upon property, payroll and sales. Insofar as Arkansas and Ward are concerned, the ratios are determined by dividing the particular factor, as it relates to Arkansas, by

218 QUALLS, DIRECTOR V. MONTGOMERY WARD & CO. [266 Ward's total for that faCtor. For example, Ward's total sales in Arkansas divided by Ward's total sales produces one fac-tor. When each of the factors is determined, they are averag­ed by adding them and dividing by three. The taxpayer's net business income is then multiplied by the resulting fraction and the result is the amount of Ward's income which is sub­ject to income tax in Arkansas. Non-business income is not apportioned, but is allocated to a certain state under the provisions of the act. Interest is one of the types of income from intangibles allocated to the domicile of the corporation, i.e., Illinois, in this case. The fact that the interest income may have been actually earned entirely within the state of Illinois is not controlling, if it is indeed business income un­der the statutory definition. The entire statutory apportion­ment formula involves items which are otherwise unrelated to Arkansas. In order to determine the net income to which is applied the Arkansas fraction resulting from the three-factor formula, deductions were made from the income shown on Ward's federal income tax returns, after the interest income involved here had been eliminated. These deductions include such items as interest expense of Ward paid for the use of funds borrowed for general business purposes. No money has been borrowed by Ward for the specific purpose of making loans or advances to affiliates or subsidiaries. Some of the in­terest expense deducted is for interest paid on loans for property acquired in other states. All interest deductible on the federal income tax return was deducted before arriving at the income taxable in Arkansas. The expense of all repairs made in all states in which Ward has facilities is likewise deducted. Bad debts on accounts receivable both within and without Arkansas are also deducted. Nationwide deprecia­tion and amortization are other such deductions.

There was no activity in Arkansas in relation to the loans and advances from which the interest in question was deriv-ed. The financial department of the office of Ward's treasurer in Chicago is the only department of the company involved. This activity is an insignificant part of the overall activities of Ward. The funds for the loans and advances come from cash available after projection of Ward's own cash needs. Ward's treasurer is responsible for the overall maintenance of Ward's financial position. He reviews all potential dispositions and

ARK.] QUALLS, DIRECTOR U. MONTGOMERY WARD & Co. 219 acquisitions. Acquiring the interest income was not the pur­pose for which the loans in question were made and making them was not considered an integral part of the funding of the merchandising operation. One of the companies to which loans were made was the holding company which owned Ward and three other cor­porations that do no business in Arkansas. Three others were real estate subsidiaries of Ward whose only function was to hold title to real estate used by Ward in the furtherance of its retail business. None of this real estate is in Arkansas. These subsidiaries and many others are operated at a loss from the standpoint of federal income tax. Among the companies were subsidiaries which sold a major part of their products to Ward. Some of them sold nothing to, and bought nothing from, Ward and have no transactions with Ward other than loans and advances made to them. One of the subsidiaries is a credit corporation that acquiries all accounts receivable of Ward. Ward retains the interest on the accounts but it seems that the finance company purchases the accounts at a dis-count. It is clear that most of the subsidiaries do no business in Arkansas and are not qualified to do business in Arkansas. None of them have any inventory, employees or physical facilities in Arkansas. There is no evidence that any of them do any business in Arkansas. The loans and advances were made to meet the cash needs of the affiliates and subsidiaries for their corporate pur-poses, including acquisition of buildings, current expenses and other legitimate business purposes. It is admitted that it is possible that they are made to fund operating losses. If some of the subsidiaries which are Ward's suppliers should go out of business, Ward would have to find new suppliers. Ward is interested in the well-being of its holding company and Ward's state and local tax manager testified that it is rather doubtful that Ward would refuse to make a loan to that company. That witness also testified that Ward was indeed interested in keeping the credit company afloat, that it would not be helpful to Ward for its subsidiaries holding title to its real estate to go bankrupt, that it was in the best business interest of Ward that the subsidiary that owned

220 QUALLS, DIRECTOR V. MONTGOMERY WARD & CO. [266 Ward's executive office building (which it had outgrown) continue in operation. He also testified that pricing policies of the subsidiaries are negotiated with Ward at arms length, just as Ward negotiates with any other supplier. The prices of one subsidiary must be the same for Ward as for other customers in order to avoid violation of anti-trust laws. Ward charges management and operations expenses to its sub-sidiaries, and either Ward or the holding company approves their budgets. Subsidiaries of Ward cannot expand their operations without Ward's approval and affiliates cannot, without the holding company's approval. The funds for loans and advances to the related cor­porations come from Ward's working capital cash. The work­ing capital represents all the liquid assets of Ward that are available in the furtherance of its business. Income earned in Arkansas and other states from retail operations and interest income on trade accounts receivable become a part of the working capital. All funds are put into a general cash reserve to be used as needed and no effort is made to segregate or isolate any of the funds derived from sales in a particular state or from returns on any investments. Loans are made to a related corporation by Ward when that corporation cannot meet its own needs for cash. Ward will supply cash to meet the needs of its subsidiaries as long as it has cash available above its own needs. Loans and advances are made regularly and consistently, and were during the three years in question, with the exception of one or two of the subsidiaries to which single loans were made for property acquisition. The loans are made for varying terms. Some are short term, and at least one is for a term of 20 years.

The "Cash Operations Manager," an employee of the Treasurer's Division of Ward, actually handles the advances to the subsidiaries, and accounts for, manages and services them and records all the advances and payments. The cash funds received as interest income from these loans are com­mingled with all other general cash funds of Ward, and become a part of Ward's working capital to be used for Ward's general corporate purposes, which may include other loans to subsidiary or affiliated corporations. As a result, money received from this interest income might be used for

ARK.] QUALLS, DIRECTOR V. MONTGOMERY WARD & Co. 221 payment for advertising in Arkansas, for inventory in Arkan­sas or payment of salaries in Arkansas; however, no effort is made to identify the flow of cash in this account. The interest on the loans and advances to corporate relatives is income from intangible property belonging to Ward. Due to the regularity and consistency of these loans and advances, the income arises from transactions and activi­ty in the regular course of Ward's business. In Champion Inter­national Corp. v. Bureau of Revenue, 88 N.M. 411, 540 P. 2d 1300 (1975), the New Mexico Supreme Court defined the phrase "transactions and activity in the regular course of the tax-payer's trade or business" in this section, thus: Business deals and the performance of a specific func­tion in the normal, typical, customary or accustomed policy or procedure of the taxpayer's trade or business. It must be remembered that these transactions are not re­quired to be in the course of Ward's regular trade. It is only required that the transactions be in the "regular course of the taxpayer's trade or business operations." See McVean Barlow, Inc. v. New Mexico Bureau of Revenue, 88 N.M. 521, 543 2d 489 (1975). The acquisition, management and disposition of the working capital most assuredly constituted an integral part of Ward's regular trade or business operation. The use to which the interest was put after it was paid is also of some significance in determining whether it is business income. Its use, just as other working capital is used, also leads to the conclusion that it is business income. Champion International Corp. v. Bureau of Revenue, supra; Montgomery Ward Co' Co. v. Commissioner of Taxation, 276 Minn. 479, 151 N.W. 2d 294 (1967). See also, Great Lakes Pipe Line Co. v. Commissioner of Taxation, 272 Minn. 403, 138 N.W. 2d 612 (1965), appeal dis-missed, 384 U.S. 718, 86 S. Ct. 1886, 16 L. Ed. 2d 881 (1966). Thus, the interest from the loans and advances clearly constitutes business income as defined in Ark. Stat. Ann. § 84-2055 (a). The fact that Ward's regular trade or business operations do not include money lending is of no significance.

222 QUALLS, DIRECTOR U. MONTGOMERY WARD & Co. 1266 Obviously, the lending of money to Ward's related cor­porations consists of transactions and constitutes an activity in the regular course of Ward's business. We cannot view these loans and advances as a mere temporary investment of idle cash, as Ward would have us do. Even if they were, any short term investment of these funds pending their eventual use in the course of Ward's regular business operations might well be apportionable. Sperry & Hutchinson Co. v. Department of Revenue, 270 Or. 329, 527 P. 2d 729 (1974); Montana Depart­ment of Revenue v. American Smelting & Refining Co., 567 P. 2d 901 (Mont., 1977), appeal dismissed, 434U.S. 1042, 98 S. Ct. 884, 54 L. Ed. 2d 793 (1978); Great Lakes Pipe Line Co. v. Com­missioner of Taxation, supra. Appellee relies upon Western Natural Gas Co. v. McDonald, 202 Kan. 98, 446 P. 2d 781 (1968), to support its contention that the interest in question is not business income. That case is not really pertinent here. The item of income held not to be business income under UDITPA in that case was the gain on the liquidating sale of oil and gas leases actually held in the state of Kansas. The Kansas Supreme Court, however, applied a basic test, not identical, but similar in effect, to that we have, i.e., that the controlling factor was the nature of the particular transaction giving rise to the income. It is said that the transaction and activity "must have been in the regu­lar course of taxpayer's business operations." We would like­ly agree with the Kansas court that the income was not ap-portionable, if we were treating the capital gain from a sale of similar assets in liquidation.

Appellee contends that two sentences added to § 84- 2055 (a) by Act 529 of 1963 (repealed by Act 1024 of 1979, after this case was submitted) clearly show that there was no legislative intent that interest on its loans to related cor­porations be included as "business income." Those two sentences read:

Business income shall include any dividends or interest paid to a corporation having its commercial domicile in this state by another corporation provided the recipient owns at least 50% of the outstanding capital stock of the distributing or paying corporation. If the recipient cor-

ARK.] QUALLS, DIRECTOR /J. MONTGOMERY WARD & Co. 223 poration owns less than 50% of the outstanding capital stock of the distributing or paying corporation, such dividends or interest shall be nonbusiness income and shall be allocated and taxed as such. We cannot agree with appellee. The basic definition of business income remained unchanged. The scope of the term was extended where a corporation, domiciled in Arkansas, and owning 50% or more of the stock of a subsidiary, would be required to include all interest paid to it by that subsidiary as business income, to be apportioned among the states in which the parent corporation did business, if those states had a formula for apportionment of business income. Only if the parent having its commercial domicile in Arkansas owned less than one-half of the stock of the subsidiary would the in­terest be allocated to Arkansas as non-business income. This does not mean that other states would have to treat such in­terest income in the same manner. But more importantly, the added sentences were not controlling when the interest arose from transactions and activities in the regular course of the parent's business and was income from money, the acquisi-tion, management and disposition of which constitute an in­tegral part of the parent's regular business operations, unless the interest was paid by a corporation in which the recipient owned less than one-half of the stock. The two sentences add­ed brought into the scope of business income for apportion­ment purposes, any interest from a subsidiary of a parent owning more than 50% of the stock of the former when the transactions and activities from which the interest was earned were not in the regular course of the parent's busi-ness, and when the acquisition, management and disposi­tion of the money lent were not an integral part of the par-ent's business. Those sentences also covered dividends, which are not involved here. The treatment of dividends from related corporations would not necessarily fall within the basic statutory definition of business income and a deter­mination whether they did before these two sentences were added would depend upon the circumstances under which the stock was acquired. It seems to us that Ward's purpose and intent in making the loans and advances were to assure financial stability and

224 QUALLS, DIRECTOR V. MONTGOMERY WARD & CO. 1266 continued operation of its corporate relatives, most of whom are suppliers of Ward or furnishers of services. Some of these borrowers who are operating at a loss probably would be hard pressed to obtain loans from other sources. Keeping these corporations "afloat" is beneficial to Ward's regular business, conducted in 49 states.

Ward's borrowers, with one possible exception, cannot expand their operations without the approval of either Ward or Ward's parent, which is also Ward's only stockholder. Management and overhead expenses are paid to Ward by its subsidiaries in relation to these loans. This is certainly not a usual or ordinary practice where a loan is made as a tem­porary investment by the lender. And, finally, the record shows that the loans and advances actually are a part of Ward's regular business operations, if that matters. We do consider that appellee's emphasis on the fact that not more than 0.4% of its total gross income and only 6% of its interest income came from loans and advances to sub­sidiaries is not justified. That fact does not seem significant to us. However small the income may be in proportion to Ward's total income does not mean that the transactions and activities giving rise to it were not in the regular course of Ward's business or the money lent not accumulated, manag­ed or disposed of as an integral part of its regular business operations. Integral does not mean indispensable or essential. See American Smelting & Refining Co. v. Idaho State Tax Commis-sion, 99 Idaho 924, 592 P. 2d 39 (1979). Ward contends that appellant's refusal to permit Ward and its related corporations to report income on the "com-bined income" method is inconsistent with his position on those items of interest. It seems to think that requiring this in­terest to be reported as business income amounts to piercing the corporate veil and identifying all the corporations as if they were one. We cannot agree with this position. In the first place, appellant is not seeking to tax the income of any of the related corporations. It is the nature of the transactions and ' activity and the source and nature (not the location) of the funds used to make the loans and advances that control, not just the identity of the corporations paying the interest. We

ARK.] QUALLS, DIRECTOR V. MONTGOMERY WARD & Co. 225 have not treated the business of Ward and its corporate relatives as forming a single "unitary business." Only recent­ly the Supreme Court of Idaho pointed out the ap­propriateness of making this distinction in American Smelting Ce Refining Co. v. Idaho State Tax Commission, supra. That court said: * * Simply because the management, operation and activity of a corporation in which the taxpayer owns stock is not so closely connected with the management, operation and activities of the taxpayer to warrant a combined tax return, does not ipso facto mean that the dividends the taxpayer receives from that stock cannot be "income arising from transactions and activities in the regular course of the taxpayer's trade or business" and that the "acquisition, management, or disposition" of the stock does not "constitute integral or necessary parts of the taxpayer's trade or business operations." I.C. § 63-3027 (a)(1). The combined reporting provision and the business income definition serve different pur-poses, ask different questions and apply different stand-ards. The answer to one does not necessarily imply the same answer to the other. Appellee makes an attack upon the regulations adopted by the revenue department, i.e., those set out at the beginning of this opinion. It contends that they are being improperly applied retroactively, and that they have never been properly adopted. The latter contention was abandoned in the trial court. We do not base our decision upon these regulations, so we need not consider the objections made by Ward. Our decision is based upon our construction of the applicable statutory provisions. The only significance of these regulations is that they reflect the revenue department's view of the proper application of the statute at the time the assess­ment was made against Ward. Since we find the interest in question to be business in-come, it is necessary that we resolve the issue of con­stitutionality raised by appellee. Ward contends that taxation of this income is a violation of the due process clause of the Fourteenth Amendment and of the commerce clause of the

226 QUALLS, DIRECTOR V. MONTGOMERY WARD & CO. 1266 United States Constitution. We do not agree. UD1TPA, as adopted in Arkansas, enjoys the presumption of con­stitutionality common to all legislative enactments, which is that it is presumptively constitutional and all doubt as to its validity must be resolved in favor of the act-Redding v. State, 254 Ark. 317, 493 S.W. 2d 116. The constitutionality of the concept of formulary appor­tionment under both the due process and commerce clauses is now well established. See Moorman Manufacturing Co. v. Bair, 437 U.S. 267, 98 S. Ct. 2340, 57 L. Ed. 2d 197 (1978). The burden is upon the taxpayer to show that a formula such as that used in Arkansas places a burden on interstate com­merce in a constitutional sense. Northwestern States Portland Ce­ment Co. v. Minnesota, 358 U.S. 450, 79 S. Ct. 357, 3 L. Ed. 2d 421, 67 ALR 2d 1292 (1959). See also, Norfolk & Western. Railway Co. v. Missouri State Tax Commission, 390 U.S. 317,88 S. Ct. 995, 19 L.

One who attacks such a formula must show by clear and cogent evidence that its use results in extraterritorial values being taxed. Butler Bros. v. McColgan, 315 U.S. 501,62 S. Ct. 701, 86 L. Ed. 991 (1941); General Motors Corp. v. State, 181 Colo. 360, 509 P. 2d 1260 (1973). See also, Fleming v. Oklahoma Tax Commission, 157 F. 2d 888 (10 Cir., 1946). The taxpayer also bears the burden of showing that application of a formula violates due process. Hans Rees' Sons, Inc. v. North

Carolina, supra. See also, Cook v. Kansas City Southern Ry. Co., 212 Ark. 253, 205 S.W. 2d 441, cert. den. 333 U.S. 873, 68 S. Ct. 902, 92 L. Ed. 1150 (1948). Appellee concedes, in its brief, that the question of arbitrariness and unreasonableness of the three-factor formula of UDITPA is not in issue. It con­tends that inclusion of the interest in question as business in­come is an attempt at extrastate taxation, prohibited by the due process clause and the commerce clause.

Taxes are imposed on corporations doing business in a state as a pecuniary charge for the protection the state affords them in their operations within the state. Great Lakes Pipe Line Co. v.

Providing an orderly market in which the taxpayer may do business is sufficient basis. General Motors Corp. v. State, supra.

A state does not violate the Fourteenth Amendment when its legislature, faced with the practical impossibility of allocating specifically the profits earned by a corporation engaged in interstate commerce through processes conducted within the borders of that state, adopts a method of appor­tionment that reaches, and was meant to reach, only the profits earned within the state.

Not only must there be some minimal connection between the business activities generating the income and the taxing state, the income attributed to the state for taxing pur­poses must be rationally related to values connected with the taxing state. Moorman Manufacturing Co. v. Bair, 437 U.S. 267, 98 S. Ct. 2340, 57 L. Ed. 2d 197 (1978).

ComMissioner of Taxation, supra. See also, Southern Pacific Co. v. McColgan, 68 Cal. App.. 2d 48, 156 P. 2d 81 (1945). It is not necessary that a state demonstrate that an apportionment formula results in exact measure . in order to avoid transgression of the due rirocess and comMerce clauses. Norfolk & Western Railway Co. v. Missouri Tax Commission, 390 U.S. 317, 88 S. Ct. 995, 19 L. Ed. 2d 1201 (1968). See also, Hans Rees' Sons, Inc. v. North Carolina, supra. Mathematical ex­actness is impossible and any method of apportionment will contain imperfections. Fleming v. Oklahoma Tax Commission, 157 F. 2d 888 (10 Cir., 1946). In considering the validity of a state's apportionment formula in the light of the prohibition against a state's burdening interstate commerce, the United States Supreme Court has recognized the practical impossibility of a state's achieving a perfect apportionment of expansive, complex, multi-state business activities, and finds a rough approxima-tion, rather than precision, sufficient. Unless it is demonstrated that an apportionment formula which includes consideration of interstate and out-of-state transactions in relation to the intrastate.privilege of doing business produces a' palpably disproportionate result, making it patent that the "tax is levied upon interstate commerce, the state's tax law will not be nullified. International Harvester Co. v. Evan, 329 U.S. 416, 67 S. Ct. 444, 91 L. Ed. 390 (1947); Moorman Manufac­turing Co. v. Bair, supra; Gulf Oil Corp. v.

Ed. 879 (1930). In considering the questions of constitutionality, it appears that neither the overall operation of related businesses in different states ., unity of ownership of stock in . separate corporations engaged in related business, nor business transactions between related corporations, creates the required integration of business operations to justify a state claiming a proportionate share of income earned

230 QUALLS, DIRECTOR U. MONTGOMERY WARD & CO. 1266 through foreign sources. See, Square D. Co. v. Kentucky Board of Tax Appeals, 415 S.W. 2d 594 (Ky., 1967), and cases cited therein. We are dealing, however, with an entirely different situation. Income earned in Arkansas went into Ward's working capital. In the regular course of Ward's business, loans and advances to related corporations earned interest which also went into working capital, a part of which was used to carry on operations in Arkansas. The interest goes into a fund that will be used, in part, in Arkansas, and the supplies and services received from the borrowers contribute to the conduct of Ward's business in Arkansas. These facts provide the necessary nexus, not to justify taxation of the total amount of this interest income, but to justify taxing that portion attributable to Arkansas under the three-factor ap­portionment formula. A fundamental part of appellee's argument that the es­sential nexus with this state for taxation is lacking is its con­tention that the loans are the investment of temporarily idle funds. We have already disposed of that contention. It seems to us that appellee's argument must fall with the basic premise of its argument. This interest involved was earned on principal which was derived, in part, from earnings in Arkan-sas.

Arkansas is not taxing the interest income from these loans and advances as such. It is simply included in the ap­portionable business income. Neither is Arkansas seeking to tax income of Ward derived outside its regular course of business or from investments totally unrelated to its regular business operations. The income tax is not levied on the par­ticular business activity of the multi-state corporate taxpayer carried on within the borders of Arkansas. It is levied on the percentage of the taxpayer's business income from all its business activity apportioned to Arkansas under the three-factor apportionment formula. This does not violate •ue process constitutional requirements. Champion International Corporation v. Bureau of Revenue, 88 N.M. 411, 540 P. 2d 1300 (1975). See also, Southern Pacific Co. v. McColgan, 68 Cal. App. 2d 48, 156 P. 2d 81 (1945). It is quite true that there is some risk of double taxation

ARK.] 231 in the "business income" definition of UDITPA, but the for­mula is designed to avoid that risk and the risk would be eliminated if all states used the three-factor apportionment formula and applied it uniformly. GTE Automatic Electric, Inc. v. .4llphin, 68 Ill. 2d 326, 12 Ill. Dec. 134, 369 N.E. 2d 841 (1977). There seems to be no significant possibility that Illi­nois will not consider that this income is apportionable. Such minimal risks are not fatal, because neither the due process clause nor the commerce clause requires total precision in multi-state taxation. Moorman Manufacturing Co. v. Bair, 437 U.S. 267, 98 S. Ct. 2340, 57 L. Ed. 2d 197 (1978); American Smelting & Refining Co. v. Idaho State Tax Commission, supra; General Motors Corp. v. State, 181 Colo. 360, 509 P. 2d 1260 (1973). We find that the interest on Ward's loans and advances from its working capital to its corporate relatives constitutes business income, as defined by Ark. Stat. Ann. § 84-2055 (a), and that the act, as thus construed and- applied, does not violate either the due process clause or the commerce clause of the United States Constitution. The decree is reversed. We agree. HARRIS, CI, GEORGE ROSE SMITH and HOLT, JJ.
