OPINION
Tannenwald, Judge:
Respondent determined that petitioners’ transfer of stock to a Canadian corporation was "in pursuance of a plan having as one of its principal purposes the avoidance of Federal income taxes,” within the meaning of section 367,1 arid that the transaction thus fails to qualify for nonrecognition treatment under section 351 or 368(a)(1)(B). Having met all jurisdictional prerequisites,2 petitioners timely filed their petition for a declaratory judgment with this Court pursuant to section 7477(a).3 The issue presented for our decision is whether respondent’s determination was reasonable.
The case was submitted for decision on the stipulated administrative record under Rule 122. This reference incorporates the administrative record herein. We assume the facts as represented therein to be true for the purposes of this proceeding. Rule 217(b)(1).
At the time they filed their petition, petitioners Millard F. Trask and M.K. Jones resided in Billings, Montana; petitioner Robert G. Pitcher resided in Red Lodge, Montana; and petitioner Mary Jane Westermark resided in Shelby, Montana. Each is experienced in the oil and gas business, and none of the petitioners is related to the others in any way. Petitioners are each considered U.S. shareholders.
Before completion of the transaction in issue, petitioners held approximately 63 percent of the 1,622,800 issued and outstanding shares of Yellowstone Petroleums, Inc. (YPI).4 YPI, a Montana corporation engaged in the oil and gas exploration business, owned property in Montana, North Dakota, and Colorado; all of its business activities have taken place in the United States. The remaining 37 percent of the YPI shares was held by Canadian corporations and individuals,5 i.e., not "U.S. shareholders.”
In 1980, YPI had lease interests in numerous oil and gas properties in the United States, but found itself with insufficient cash to commence drilling on these properties. Under the typical lease agreements, YPI was required to commence drilling in order to retain its interest in the properties; if these drilling obligations were not met, YPI faced a substantial risk of losing potentially profitable property interests. Moreover, YPI needed capital to acquire additional properties. The management of YPI found that a public stock offering would be the most rapid and cost-effective method with which to raise the requisite capital. A domestic public offering would have entailed excessive expenditures of time and money because of the necessity of registration of the offering with the U.S. Securities and Exchange Commission (SEC). Thus, management decided upon a foreign public offering. Canada was chosen as the optimal location for the offering because of the geographic location of YPI, prior joint venture dealings and business contacts with Canadian investors, the relation of one of the Canadian shareholders with a brokerage firm in Calgary, and the belief that the Canadian market would be more receptive to the offering than would the U.S. market.
Initially, management considered offering YPI stock on a Canadian exchange. However, the SEC became aware of this plan and expressed its concern about the fact that YPI had not registered its offering. To avoid problems with U.S. securities laws, attorneys for YPI advised the SEC that severe restrictions would be placed on the offered YPI shares, namely, a legend stating that transfers were to be made in Canada, only, and that no transfers were to be made to any citizen or resident of the United States, or to any agent of U.S. citizens or residents.
However, these restrictions so impaired the marketability of the YPI shares that the transfer agent and underwriter would not accept the YPI stock so legended. Thus, management decided to form a Canadian corporation — Yellowstone Petroleums, Ltd. (YPL) — to act as a holding company with its only assets being all the outstanding stock of YPI, and to offer the shares of YPL on the Canadian exchange. The transaction to which petitioners’ ruling request referred, entailed (1) an exchange by the eight YPI shareholders of all their outstanding YPI shares for an equal number of YPL shares, and, shortly thereafter, (2) a public offering on a "best efforts” basis6 for between 500,000 and 1 million shares of YPL on a Canadian exchange. After the first step of the transaction, YPI would become a wholly owned subsidiary of YPL, the former shareholders of YPI would own 84.6 percent of the 1,942,800 YPL shares issued and outstanding, and petitioners (the former YPI shareholders who were "U.S. shareholders”) would own 52.6 percent of the YPL shares. After the second step, the former YPI shareholders would own between 55.8 percent and 67.3 percent of YPL, and petitioners would own between 34.8 percent and 41.9 percent of the YPL shares.7
On February 3, 1981, in order to accomplish their stated business purpose, petitioners effected the proposed transaction with the sale of 1 million shares of YPL on the Alberta Stock Exchange (ASE) for $2.60 (Canada) per share. After completion of the transaction, the former YPI shareholders owned 55.8 percent of the YPL shares, and petitioners owned 34.8 percent. As of the date of the transaction, petitioners held three of the six positions on the YPL board of directors and held the offices of president, chairman of the board, vice president, chief financial officer, and secretary/treasurer of YPL. All of the former YPI shareholders then held four YPL positions. The directors and senior officers of YPL together held options to purchase a total of 175,000 additional common shares of YPL.
YPL and YPI represented to respondent that petitioners had no intention of disposing of their stock in YPL, and that YPL had no intention of disposing of its YPI stock or to liquidate YPI or otherwise to have YPI or YPL abandon the oil and gas business. Petitioners’ transfer of their YPL shares would require, pursuant to a legend inscribed on their YPL share certificates in accordance with Alberta law, (1) filing a prospectus with the Alberta Securities Exchange Commission (ASC), or (2) filing a statement of material facts with the ASC and ASE, or (3) obtaining an order from the ASC, or (4) following Canadian procedures for a transfer pursuant to a consolidation, amalgamation, merger, or reorganization. Under Canadian law, the last of these would require approval of three-fourths of the YPL shareholders, disclosure to the ASE, and acceptance by the ASE. A transfer by YPL of all of its YPI shares would, under Canadian law, require approval by the board, majority shareholder approval, and acceptance for filing of a notice to the ASE.
Petitioners requested a ruling from respondent on the proposed transaction on July 15, 1980. Respondent issued an initial adverse ruling letter with respect to the transaction on February 27,1981.8 In their protest9 to this ruling, dated April 11, 1981, petitioners offered to enter into a closing agreement with respondent "whereby [petitioners] would recognize any inherent gain not recognized under any other provisions of the Internal Revenue Code if at any time prior to January 1,1985, YPL should dispose of any YPI stock.” On June 3, 1982, respondent issued a final adverse ruling on the transaction and declined to enter the proposed closing agreement.10
Section 36711 provides that for certain exchanges and reorganizations in which property is transferred by a U.S. person to a foreign corporation, the corporation will not be considered to be a "corporation” for tax purposes unless the taxpayer establishes to respondent’s satisfaction that the exchange is not in pursuance of a plan having as one of its principal purposes the avoidance of Federal income taxes. Because corporate status is essential to nonrecognition treatment under sections 351 and 368(a)(1), section 367 requires that taxpayers obtain a favorable ruling in order to qualify incorporations and reorganizations involving transfers to foreign corporations for nonrecognition treatment. The present case falls within the requirements of section 367 due to the coverage of petitioners’ two-step transaction by section 351.12
Section 367 initially appeared in the Code as section 112(k) of the Revenue Act of 1932, Pub. L. 72-154, 47 Stat. 169. Congress’ purpose in enacting section 112(k) was to close a "serious loophole” in existing tax law that allowed taxpayers to avoid taxation of the capital gain on the sale of appreciated securities by transferring the securities to corporations "organized in countries imposing no tax upon the sale of capital assets.” S. Rept. 665, 72d Cong., 1st Sess. (1932), 1939-1 C.B. (Part 2) 496, 515 (hereinafter cited as 1932 Senate Report); H. Rept. 708, 72d Cong., 1st Sess. (1932), 1939-1 C.B. (Part 2) 457, 471 (hereinafter cited as 1932 House Report). Until 1976, the core substantive concept in section 112(k) (and later section 367) — whether the transaction in question was "in pursuance of a plan having as one of its principal purposes the avoidance of Federal income taxes” — remained unchanged. See Aidinoff & Mosley, "Section 367(a) — Janus Revisited,” 36 Tax Law. 629, 630 (1983).
In 1968, in order to make clear the circumstances under which an advance ruling would be granted under section 367, the Service published detailed guidelines describing when a favorable ruling would or would not ordinarily be issued. Rev. Proc. 68-23, 1968-1 C.B. 821 (the Guidelines). For purposes of this case, the relevant general rule is that "a favorable ruling under section 367 of the Code will not be issued for an exchange described in section 351 of the Code where the property to be transferred to the foreign corporation is * * * stock or securities.” Guidelines, sec. 3.02(1)(a)(iii). However, respondent recognized in another section of the Guidelines, section 3.03(1)(d), a specific exception to the general rule in section 3.02(1)(a). This exception provides that a favorable ruling will ordinarily be given—
Where the stock of a domestic corporation is acquired in exchange for stock of a foreign corporation and immediately after the exchange the shareholders of the acquired domestic corporation do not own directly or indirectly, within the meaning of section 958 of the Code, more than 50 percent of the total combined voting power of all classes of stock entitled to vote of the acquiring foreign corporation, unless the assets of the acquired domestic corporation consist principally of stock or securities. [Guidelines, sec. 3.03(l)(d).]
Notwithstanding the foregoing specific rules, Guidelines section 2.02 sets forth an overall test as follows:
In reviewing each request, for ruling to determine whether a favorable section 367 ruling should be issued under the guidelines, the Service reserves the right to issue an adverse ruling if, based on all the facts and circumstances of a case, it is determined that the taxpayer has not established that tax avoidance is not one of the principal purposes of the transaction. Similarly, a taxpayer shall be free to establish that based on all the facts and circumstances of the taxpayer’s case a favorable ruling under section 367 of the Code should be issued, notwithstanding a contrary statement or implication contained in the guidelines. [Emphasis added.]
Thus, under the Guidelines, failure to fit a transaction within a specific guideline is not necessarily fatal on the question of principal purpose. See Kaiser Aluminum & Chemical Corp. v. Commissioner, 76 T.C. 325, 343-344 (1981); Dittler Bros., Inc. v. Commissioner, 72 T.C. 896, 913 (1979), affd. without published opinion 642 F.2d 1211 (5th Cir. 1981).13
In 1976, as part of the Tax Reform Act of 1976, Pub. L. 94-455, 90 Stat. 1520, Congress restructured section 367 and provided for declaratory judgment jurisdiction of this Court to give taxpayers a forum in which to protest respondent’s adverse rulings under that section. The restructuring did not change the "principal purposes” language carried forward from section 112(k), and it is this portion of the statute that is essentially at issue in the present case.14 Petitioners contend that, because the transaction fits within the mold of Guidelines section 3.03(l)(d), and the facts and circumstances indicate that business reasons primarily motivated the transaction,15 respondent’s conclusion that tax avoidance was one of the principal purposes of the transaction in issue is not supported by substantial evidence. Further, petitioners argue that respondent’s refusal to enter into an appropriate agreement demonstrates the unreasonableness of respondent’s ruling.
Respondent, claiming that the appropriate standard of review is whether his determination was arbitrary and capricious, asserts that section 3.03(1)(d) does not cover this transaction, that the purpose for the transaction was deferral and avoidance of U.S. tax, and that the facts and circumstances thus indicate that respondent’s ruling is reasonable.
Section 7477(a)(2), as noted above, requires this Court to declare, inter alia, "whether or not [respondent’s] determination is reasonable.” In the three cases decided by this Court to date under section 7477, we have consistently held that the proper standard of review under this statute is the "substantial evidence” standard. See Kaiser Aluminum & Chemical Corp. v. Commissioner, supra at 343; Hershey Foods Corp. v. Commissioner, 76 T.C. 312, 317 n. 7 (1981); Dittler Bros., Inc. v. Commissioner, supra at 909-910. Respondent argues that the "mood” of Congress, as expressed in the enactment of sections 112(k), 367, and 7477, indicates that we are to give respondent almost unlimited discretion in ruling on section 367 transactions. We do not agree. As we held in Dittler Bros., by directing the Court to determine the reasonableness of respondent’s section 367 determinations, Congress, in 1976, withdrew the unbridled discretion that respondent perhaps was once given.16 The proper test, falling "somewhere between the arbitrary and capricious test and a simple redetermination” (72 T.C. at 910), is the substantial evidence test, under which we are to determine whether respondent’s ruling is supported by " 'such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.’ ” 72 T.C. at 909 (citation omitted). We reject respondent’s plea that we reconsider our prior decisions, abandon the "substantial evidence” test, and adopt an "arbitrary and capricious” test.17
After a careful review of the entire administrative record, we conclude that respondent’s determination that one of petitioners’ principal purposes was the avoidance of Federal income taxes is not supported by substantial evidence, and is thus unreasonable.
Our analysis begins with the Guidelines, which were followed by respondent at the time of his adverse determination regarding petitioners’ transaction. See Rev. Proc. 77-5, sec. 3.03, 1977-1 C.B. 536, 538. Petitioners argue that, because their transaction fits section 3.03(1)(d) of the Guidelines as they interpret it, upholding respondent’s ruling would constitute subversion of their reasonable reliance on the Guidelines in structuring their affairs. Respondent claims that, because the transaction is covered by section 3.02(1)(a) of the Guidelines as he interprets it, the unfavorable ruling is reasonable. In interpreting the Guideline provisions, both parties expend much effort arguing whether "the shareholders of the acquired domestic corporation,” i.e., the group under section 3.03(1)(d) that must own 50 percent or less of the acquiring foreign corporation immediately after the exchange, encompasses only the U.S. shareholders of YPI (petitioners) or all the former shareholders of YPI. Moreover, the parties are in dispute over whether the control test in section 3.03(1)(d) includes a determination of "effective, practical control” where the 50-percent control test is not met. Although these issues are interesting, they are subsidiary to the basic issue in this and other cases under section 367, namely, whether the transaction had, as one of its principal purposes, tax avoidance. In light of our conclusion on that issue, we do not reach the "shareholder” definition issue or the issue of "effective, practical control” posed by the parties.
The Guidelines are not positive law, but were promulgated to give taxpayers guidance regarding respondent’s ruling policy under the statutory "principal purposes” standard (Dittler Bros., Inc. v. Commissioner, 72 T.C. at 914) — a standard never elucidated by Congress or by respondent, see Himmel, "The Section 367 Toll-Charge Requirement: Impact of the Gerli Case,” 8 International Tax J. 276, 284 (1982). Although Congress, as respondent maintains, did generally approve of the Guidelines in 1976, it clearly indicated that declaratory judgment relief for taxpayers issued adverse rulings under section 367 was necessary because "there may be cases where these standards are inappropriate or are not being correctly applied.” H. Rept. 94-658 (1975), 1976-3 C.B. (Vol. 2) 695, 933; S. Rept. 94-938 (1976), 1976-3 C.B. (Vol. 3) 49, 301. Hereinafter cited as 1975 House Report and 1976 Senate Report. It is section 367, itself, and not the specific Guidelines provisions, that is the positive law which respondent must follow in issuing rulings; the Guidelines serve only to implement the principal purposes test in section 367.18 Indeed, the Guidelines, themselves, reflect this fact in section 2.02 (see supra p. 91), which overrides the application of specific provisions of the Guidelines by allowing either the Service or a taxpayer to argue principal purposes from all the facts and circumstances. Accordingly, this Court has consistently rejected a rigid, mechanical application of the Guidelines. Kaiser Aluminum, & Chemical Corp. v. Commissioner, supra at 343-344, 346-347; Dittler Bros., Inc. v. Commissioner, supra at 912-914; see generally Johnson, "A Criticism of the Internal Revenue Service Standards Used in Evaluating Section 367(a)(1) Ruling Requests,” 61 Taxes 749, 752-753 (1983).19
Thus, we direct our attention not to whether petitioners’ transaction fits the detailed requirements for a favorable ruling under Guidelines section 3.03(l)(d), but, instead, to whether, given all the facts and circumstances disclosed in the administrative record, respondent’s determination that the transaction had tax avoidance as one of its principal purposes is supported by substantial evidence.
As we held in Dittler Bros., Inc. v. Commissioner, supra, the proper test for whether tax avoidance was a principal purpose is not, as respondent urges, whether a tax-avoidance purpose "figures prominently as a reason for the plan,” or whether business reasons are "so overwhelming as to make tax avoidance a negligible concern,” but, rather, whether the transaction had "as one of its 'first-in-importance’ purposes the avoidance of Federal income taxes.” 72 T.C. at 915.
Respondent argues that petitioners’ transaction was precisely the type which Congress had in mind when it enacted section 367 — "the classic avoidance transaction.” Acknowledging that the "concept of tax avoidance is not always an easy one to grasp or define,” respondent finds tax avoidance in the fact that YPL could have sold its appreciated YPI stock free of U.S. tax at any time before the date on which section 89720 overrides the treaty between the United States and Canada exempting the gain from tax,21 and thus avoided U.S. income tax on the appreciation accruing in YPI. According to respondent, petitioners’ business purpose arguments are "weak” in light of what he claims to be substantial evidence of tax avoidance and petitioners’ effective control of YPL — the instrument through which the tax on YPI’s appreciation could be avoided. Pointing to the fact that the delayed effective date of section 897 gives the foreign YPL shareholders an incentive to avoid taxes causing the YPI shares to be sold quickly, respondent concludes that "the facts here do not lead one to an inevitable conclusion that tax avoidance played an immaterial role.”
Petitioners, citing the "first in importance” standard, claim that they adequately demonstrated that business, not tax, considerations dominated their thinking. They point to the need for capital, the relative efficiency and effectiveness of a Canadian public offering to obtain the capital, the need to form YPL in order to make the offered shares marketable, and the restrictions on the sale of the YPI shares by YPL. Noting that they remain willing to agree to recognize any inherent gain not otherwise recognized on the sale of the YPI shares, petitioners conclude that respondent’s determination ignores "both a business purpose for the transaction and a lack of interest on the part of Petitioners to avoid tax.”
We agree with petitioners. Respondent’s argument that one of the principal purposes here was tax avoidance really breaks down into two parts — that there was a potential for tax avoidance inherent in the transaction, and that taxes were deferred as a consequence of the transaction. Respondent argues that potential avoidance was within the scope of Congress’ aim in passing the predecessor to section 367. Describing an example of the kind of transaction to be covered by section 112(k), the committee reports stated—
For example, A, an American citizen, owns 100,000 shares of stock in Corporation X, a domestic corporation, which originally cost him $1,000,000 but now has a market value of $10,000,000. Instead of selling the stock outright A organizes a corporation under the laws of Canada to which he transfers the 100,000 shares of stock in exchange for the entire capital stock of the Canadian company. This transaction is a nontaxable exchange. The Canadian corporation sells the stock of Corporation X for $10,000,000 in cash. The latter transaction is exempt from tax under the Canadian law and is not taxable as United States income under the present law. The Canadian corporation organizes Corporation Y under the laws of the United States and transfers the $10,000,000 cash received upon the sale of Corporation X’s stock in exchange for the entire capital stock of Y. The Canadian corporation then distributes the stock of Y to A in connection with a reorganization. By this series of transactions, A has had the stock of X converted into cash and now has it in complete control. [1932 Senate Report, supra, 1939-1 C.B. (Part 2) at 515; 1932 House Report, supra, 1939-1 C.B. (Part 2) at 471.]
Respondent argues that regardless of the fact that, in this example, the appreciation in the value of the X stock, represented by corporation Y’s cash, will be taxed if and when there is an eventual distribution to A, Congress enacted the predecessor to section 367 so as to attack the potential avoidance resulting from A’s control over the distribution. This Court has applied this rationale and held that a potential for tax avoidance "should be an element to be considered” in determining whether a tax-avoidance purpose pervaded the transaction. Dittler Bros., Inc. v. Commissioner, 72 T.C. 896, 917 (1979), affd. without published opinion-642 F.2d 1211 (5th Cir. 1981); cf. Hershey Foods Corp. v. Commissioner, 76 T.C. 312, 318 (1981) (if no tax-avoidance potential exists, tax avoidance cannot be a principal purpose).
However, Congress has also stated that this potential, alone, is not enough. Enumerating the problems with the pre-1976 enforcement of section 367, the committee reports mention as an area of difficulty "situations where the IRS requires a U.S. shareholder to include certain amounts in income as a toll charge even though there is no present tax-avoidance purpose but, rather, only the existence of a potential for future tax avoidance.” 1975 House Report, supra, 1976-3 C.B. (Vol. 2) at 932; 1976 Senate Report, supra, 1976-3 C.B. (Vol. 3) at 301.22 A potential for avoidance, then, is not dispositive, but is only one of the "facts and circumstances” to be considered, and the actual likelihood of the future actions that will result in avoidance is highly relevant. See Kaiser Aluminum & Chemical Corp. v. Commissioner, 76 T.C. 325, 347 (1981).23 The example given in the 1932 House Report, supra, and 1932 Senate Report, supra, is devoid of any reference to business purpose, which has always been a critical element in finding the proscribed purpose contained in section 367. We reject respondent’s attempt to persuade us to convert a distinguishable example in a legislative committee report into a mandate which establishes an inflexible rule — a status not even adopted by respondent in his own Guidelines.
In the instant case, future tax avoidance could result only if YPL sells its YPI shares before the date on which section 897 becomes effective.24 There is indeed a potential for avoidance of U.S. taxes on the appreciation in YPI if this occurs. The question, however, is whether substantial evidence supports respondent’s determination that, on all the facts and circumstances, tax avoidance was a principal purpose of this transaction.
YPI clearly needed capital in order to continue profitable operations, and the management of YPI decided that a public offering was the optimal approach. A foreign offering avoided the time and money involved with the SEC registration needed for a domestic offering. Management chose Canada due to prior dealings with Canadian investors, geographic proximity, and a favorable market outlook. YPL was formed to avoid marketability problems which, due to SEC restrictions, would accompany a U.S. offering or, indeed, a Canadian offering, of YPI stock. These restrictions would not only have been imposed on the’ subsequent transfers of YPI stock offered to the public, but would have operated directly on the offering of the shares, themselves. They appear to be far more onerous than those involved in the YPL offering, where the restrictions seem to have been imposed only on the subsequent transfers of the YPL shares in the hands of former YPI shareholders. If the restrictions accompanying the Canadian offering had not been less onerous, it would seem that the Canadian underwriter and transfer agent would have been as unwilling to undertake an offering of YPL shares as they were in respect of an offering of YPI shares in Canada. Finally, we think it significant that the initial plan was to offer YPI shares, in which case section 367 would have had no relevance. It was only after the SEC voiced its concern, and after the restrictions proposed to be attached to the offering of YPI shares were found to be unacceptable by the Canadian underwriter and transfer agent, that the decision to offer shares of YPL was made and section 367 came into play.25
We are unimpressed by respondent’s argument that petitioners, because of their board positions and offices and their options to purchase YPL stock, had practical control of YPL sufficient to enable them to force a tax-avoiding sale of YPI shares, and that the grace period effected by section 897 would give the Canadian YPL shareholders a motive to see YPI sold prior to the override date in order to avoid a U.S. tax. We think respondent is grasping at straws in an effort to persuade us to hold that tax avoidance was one of the principal purposes of the exchange involved herein. The fact of the matter is that the petitioners are four unrelated persons. Their common interest was to stay in the oil and gas business, an interest which would have been subverted, if not defeated, by a sale of the YPI shares. As far as the Canadian shareholders of YPL were concerned, any tangential incentive to avoid a future U.S. tax was clearly subordinated to the necessity of compliance with the restrictions imposed by Canadian law on the sale of the YPI shares by YPL. Moreover, any doubts relating to the significance of any tax-avoidance purpose during the section 897 grace period26 are further minimized by the offer of a closing agreement by petitioners — a matter to which we now turn our attention in connection with respondent’s attempt to equate deferral of tax with avoidance of tax.
Respondent argues that the deferral component of petitioners’ transaction warrants his adverse determination. As respondent puts it, "In modern tax parlance, a tax deferred is a tax saved.” In fact, given petitioners’ willingness to enter into a closing agreement to recognize any inherent gain on an eventual sale of the YPI shares not otherwise recognized prior to the expiration of the grace period,27 it would seem that it is only the deferral of taxation that respondent can be arguing as the present tax avoidance in this case.28 The problem, however, with equating deferral with section 367 avoidance is that every transaction that qualifies for a section 367 ruling request is a nonrecognition transaction. By definition, income tax is deferred when a transaction qualifies as a nonrecognition incorporation, reorganization, or liquidation, until the stock or assets involved are transferred in a recognition transaction. Thus, if deferral alone were enough, there could never be a favorable ruling under section 367 — a result that Congress obviously did not intend. See generally Aidinoff & Mosley, "Section 367(a) — Janus Revisited,” 36 Tax Law. 629, 640, 655 (1983).29 Certainly, the Commissioner has a legitimate interest in taxpayers’ deferrals of taxes (see Sitrick, "Section 367 and Tax Avoidance: An Analysis of the Section 367 Guidelines,” 25 Tax L. Rev. 429, 432 (1970)), but deferral, alone, cannot be equated with avoidance under section 367.
Respondent’s all-or-nothing approach to proposed closing agreements — noted in Kaiser Aluminum & Chemical Corp. v. Commissioner, 76 T.C. 325, 349-351 (1981), and apparently still followed today (see H. Rept. 98-432 (Part 2) 1311 (1984); 61 J. Taxation 268, 269 (1984)) — is no less unreasonable on the facts of the instant case than it was in Kaiser Aluminum. Where adoption of a proposed closing agreement would reduce the tax-avoidance possibilities to the level of those that would exist in any domestic incorporation transaction (i.e., deferral), respondent’s refusal to enter the agreement or even to negotiate it is an element that ought to be considered in determining the reasonableness of his determination that avoidance of Federal income taxes was one of the principal purposes of the transaction. In light of Congress’ approval in 1976 of a standard that permits nonrecognition treatment of transfers of liquid or passive investment assets outside the United States when the tax on the potential earnings from these assets "is paid or is preserved for future payment” (1975 House Report, supra, 1976-3 C.B. (Vol. 2) at 932; 1976 Senate Report, supra, 1976-3 C.B. (Vol. 3) at 300 (emphasis added); see also H. Rept. 98-432 (Part 2), supra at 1316 (generally reapproving this standard)), respondent’s arguments about the enforceability and allegedly undue flexibility of closing agreements are simply unpersuasive. See Kaiser Aluminum & Chemical Corp. v. Commissioner, supra at 349-350. Indeed, we note that the policing difficulties to which respondent points in connection with the proposed closing agreement with respect to a transfer of YPI stock by YPL taking place before the override date seem to be no different from those which will exist after the grace period contained in section 897 expires.30
Because the administrative record fails to disclose substantial evidence of a principal purpose, of tax avoidance, either in the way of potential avoidance or tax deferral, we conclude that respondent’s adverse determination is unreasonable within the meaning of section 7477(a)(2)(A) and that YPL will thus qualify for corporate status under section 367.
An appropriate decision will be entered.
