Opinion by
Judge Kramer,
This is an appeal filed by Logan Clay Products Company (Logan) from an order of the Board of Finance and Revenue (Board) denying Logan’s petition for resettlement of Logan’s Corporate Net Income Tax for the fiscal year ending November 30, 1964. Logan had reported its Corporate Net Income Tax as $1,614.45 and had filed its tax return timely. On January 18, 1966, the Department of Revenue (Department) mailed Notice of Settlement to Logan assessing a deficiency in its [631]*631Corporate Net Income Tax for the said period in the amount of $5,031.18 (exclusive of interest and penalty). The Department settled the tax at $6,645.63, thereby creating the alleged deficiency. After the appeal was filed, the matter came up for a hearing de novo before this Court. A record was made, the matter was fully briefed and argued before the Court en Bane. It is now ripe for determination.
The basic issue before the Court is whether Logan, which operates in several states, is engaged in a unitary or multiform business for Pennsylvania Corporate Net Income Tax purposes. The determination of that issue will resolve all of the questions raised by Logan and the Board.
Findings of Faqt

88. Ninety percent of the Ohio Division’s production consisted of the manufacture of sewer pipe.
89. The Ohio Division’s unglazed sewer pipe was made using a mixture of approximately 50 percent fire clay and 50 percent shale. This is different from the mixture used in manufacturing the sewer pipe in Pennsylvania.
[640]*64090. The sewer pipe manufactured by the Ohio Division does not appear to be the same product as that manufactured in Pennsylvania. The Ohio pipe is a dull, light reddish-brown color. The clay sewer pipe manufactured at the Graff plant is “salt glazed,” which gives the product a shiny, dark brownish-red appearance. Drain tile manufactured by the Pennsylvania Division was not manufactured by the Ohio Division.
91. The Ohio Division made a reduced diameter pipe, which was not generally interchangeable with products manufactured by the Pennsylvania Division. The Pennsylvania Division made only full dimension pipe.

102. The combined company taxable federal net income for the tax year was $252,101.05.
103. The taxable net income using the Pennsylvania Corporate Net income allocation formula which treats Logan’s business as unitary, resulted in attribution of income to the Pennsylvania Division in the amount of $137,667.00. This allocated 32.88 percent of Logan’s taxable net income to Pennsylvania and 67.12 percent to Ohio.
104. For the tax year, the gross income of the Pennsylvania Division was $1,524,647.50. The gross income of the Ohio Division was $3,787,092.25 for the same year.
105. The labor costs resulting from the Pennsylvania Division operations were $851,370.26, and the labor costs for the Ohio Division operations were $1,-100,485.15.
106. It was stipulated at trial that if this Court holds the Logan operations to be multiform, the computations shown on Logan’s filed Pennsylvania Corporate Net Income tax return are correct.
Discussion
As we stated at the beginning, the issue confronting us is whether the income generated by Logan’s multi-state operation should be included in the formula computation used in determining Logan’s Corporate [642]*642Net Income Tax owed to the Commonwealth for the tax year. The statute involved is paragraph 1(b) of Section 2 of the Corporate Net Income Tax Act,1 Act of May 16, 1935, P.L. 208, 72 P.S. §3420b 2. (c)(3) (hereinafter CNI Tax Act), which reads in pertinent part: “Where a corporation in any tax year beginning on or after the first day of January, one thousand nine hundred fifty-six, engages in a separate business outside of Pennsylvania, or owns property having a situs outside of Pennsylvania, which business or property bears no relation to the exercise of the Pennsylvania franchise, the department, with the approval of the Auditor General, may determine the base for the tax imposed by this act for the tax year by excluding from the net income of such corporation as returned to and ascertained by the Federal Government, the net income from the business or property which bears no relation to the exercise of the Pennsylvania franchise.”
The Commonwealth contends that Logan has not met its burden of proving that it was entitled to a multiform tax settlement for the tax year. It argues that Logan’s operation was unitary because both the Pennsylvania and Ohio Divisions of Logan were engaged in the business of producing and selling “clay products.” Logan counters this argument by contending that the two divisions were operated independent of each other and that although they sold similar products, they were completely different operations and thereby multiform. Under the CNI Tax Act, in a multiform situation, exclusion of outj-of-state income was permitted where the taxpayer had been engaged in a separate business outside of Pennsylvania. See Commonwealth v. ACF Industries, Incorporated, 441 Pa. 129, 271 A. 2d 273 [643]*643(1970); Morewood Realty Corporation v. Commonwealth, 6 Pa. Commonwealth Ct. 244, 294 A. 2d 219 (1972).
The current state of the law concerning what is “multiform” has been set forth by our Supreme Court in Commonwealth v. ACF Industries, Incorporated, supra. In that case Mr. Justice Cohen described the multiform concept as an attempt to avoid an impermissible taxation of income by Pennsylvania; and an effort to insure that the allocation of taxable value to Pennsylvania bears a fair relation to the amount of local business done by the corporation within the Commonwealth. He delineated the principles to be applied in a multiform situation as follows:
“First, if a multistate business enterprise is conducted in a way that one, some or all of the business operations outside Pennsylvania are independent of and do not contribute to the business operations within this State, the factors attributable to the outside activity may be excluded.
“Second, in applying the foregoing principle to a particular case, we must focus upon the relationship between the Pennsylvania activity and the outside one, not the common relationships between these and the central corporate structure. Only if the impact of the latter on the operating units or activities is so pervasive as to negate any claim that they function independently from each other do we deny exclusion in this contest.
“Third, without attempting to preclude exclusion in any given case, we reiterate our statement above that the manufacturing, wholesaling and retailing (or manufacturing and selling) activities of a single enterprise are not fit subjects for division or partial exclusion. On the other hand, a truly divisionalized business, conducting disparate activities with each division internally integrated with respect to manufacturing and selling, [644]*644may well be in a position to make a valid claim for exclusion.” 441 Pa. at 142-143, 271 A. 2d at 280.
We also must note that “the burden is on the taxpayer to show by clear and cogent evidence that the taxing formula resulted in extraterritorial values being taxed.” Commonwealth v. American Telephone and Telegraph Company, 382 Pa. 509, 516, n.2, 115 A. 2d 373, 376 n.2 (1955); also see Commonwealth v. Emhart Corporation, 443 Pa. 397, 278 A. 2d 916 (1971). Furthermore, “[t]he proper standard to be utilized in evaluating whether a taxpayer has satisfied his burden as to an unrelated asset is to determine if there is clear evidence that the asset is not ‘ “a necessary part of the corporate activity” ’. Commonwealth v. The Mundy Corporation, 346 Pa. 482, 484, 30 A. 2d 878, 879 (1943). . . .” Commonwealth v. Emhart Corporation, 443 Pa. at 404, 278 A. 2d at 919.2
In most of the cases where the courts have held the business activity to be multiform, the facts of the cases disclosed a definitive difference between the out of state operation and the operation within the Commonwealth. For example, in Commonwealth v. Baker Whiteley Coal Company, 74 Pa. D. & C. 13 (1950), the court easily distinguished the difference between a tugboat operation and the mining of coal. In Commonwealth v. The Mundy Corporation, supra, the Court distinguished between the taxpayer’s real estate bus[645]*645iness and its investment in securities. In Advance Wilson Industries, Inc. v. Commonwealth, 7 Pa. Commonwealth Ct. 14, 297 A. 2d 835 (1972), this Court distinguished the manufacture and sale of ceramic tile with another operation involving the plating of parts and tools by an electrolyzing process.
The facts of this case as found by this Court present a much closer question when comparing Logan’s business interests in Ohio and Pennsylvania. It is true, as the Commonwealth contends, that both the Ohio Division and Pennsylvania Division were involved in the production and sale of clay products. However, when the principles set forth in Commonwealth v. ACF Industries, Incorporated, supra, are applied, we conclude that the two operations were independent of each other and neither contributed to the business operation of the other during the tax year in issue. We further conclude that the Ohio Division did not contribute to the business operations of the Pennsylvania Division. According to our Findings of Fact, the Pennsylvania Division did not rely on the Ohio Division for anything other than rather cursory or superficial visits by Logan officials and the annual audit, both of which are de minimis and fail to establish any interdependence.
The real test in this case is whether Logan’s business activity in Ohio contributed to or was related to or was an integral part of the business activity of the Pennsylvania Division. In other words, did the Ohio Division business operation contribute to the exercise of the franchise of Logan in Pennsylvania? From our Findings of Fact, we conclude that there was no reasonable relationship between the Ohio Division, which was sought to be included within the tax formula by the Commonwealth, and the Pennsylvania Division. In other words, Logan’s Ohio Division activities neither enhanced nor diminished its business activities in Pennsylvania. See Commonwealth v. Kirby Estates, Inc., [646]*646432 Pa. 103, 246 A. 2d 120 (1968). In Commonwealth v. L. D. Caulk Co., 11 Pa. D. & C. 2d 218 (1956), the court stated: “Multiformity in business activity exists where two separate and segregated enterprises are not related to each other and are conducted as separate and independent units, and the corporation derives benefits from each independent unit that are not related to the operation of the other units.” 11 Pa. D. & C. 2d at 223.
Conclusions of Law
1. For Pennsylvania Corporate Net Income Tax purposes in the tax year ending November 30, 1964, Logan was engaged in two separate and unrelated businesses.
2. Although both the Pennsylvania and the Ohio Divisions of Logan were involved in the business of producing clay products, the type of clay products produced by each division were significantly different and were not interchangeable to any substantial degree. Therefore, the business operation of the Ohio Division did not contribute to. the business operation of the Pennsylvania Division.
3. There was no interrelationship between the business operation of the Ohio and the Pennsylvania Division thereby negating any connection between the business operation of the Ohio Division and the privilege granted by Pennsylvania to conduct business in this Commonwealth.
4. Logan has met its burden of proving that it is entitled to a multiform tax settlement for the tax year ending November 30,1964.
5. The Commonwealth may not include Logan’s entire taxable income derived in all states in arriving at a settlement of Logan’s Corporate Net Income Tax for the tax year in issue.
Accordingly, we issue the following
[647]*647Order
And now, this 28th day of January, 1974, the appeal of Logan Olay Products Company from the decision of the Board of Finance and Revenue denying Logan’s petition for resettlement of its Pennsylvania Corporate Net Income Tax for the fiscal year ending November 30, 1964, is sustained; and unless exceptions be filed to this Order within thirty days hereof, it is ordered that judgment be entered in favor of the Commonwealth and against Logan Clay Products in the amount of $1,614.45, together with interest and costs which shall be paid accordingly and with a credit allowed to the said company for such amount, if any, as it has paid on such tax obligation. The Prothonotary is directed to notify forthwith the parties hereto or their counsel of this Order by personal service or by U. S. registered mail.
