The linchpin of the government’s argument is the application of the step transaction doctrine. Unquestionably, if these transactions are amalgamated and viewed in their entirety, the continuity of interest requirement is not satisfied. In order to evaluate properly the government’s argument, we therefore turn to an exposition of the step transaction doctrine.
B. The Step Transaction Doctrine
1. Articulating the Standards
The step transaction doctrine is a corollary of the general tax principle that the incidence of taxation depends upon the substance of a transaction rather than its form. See Kuper v. Commissioner, 533 F.2d 152, 155 (5th Cir.1976) (citing cases). Under the step transaction doctrine, “the tax consequences of an interrelated series of transactions are not to be determined by viewing each of them in isolation but by considering them together as component parts of an overall plan.” Crenshaw v. United States, 450 F.2d 472, 475 (5th Cir.1971). When considered individually, each step in the series may well escape taxation. The individual tax significance of each step is irrelevant, however, if the steps when viewed as a whole amount to a single taxable transaction. Id. at 476. “[Taxpayers] cannot compel a court to characterize the transaction solely upon the basis of a concentration on one facet of it when the totality of circumstances determines its tax status.” Id. at 477.
The types of step transactions are as varied as the choreographer’s art: there are two steps, waltzes, fox trots, and even Virginia reels. As a consequence, the courts’ applications of the step transaction doctrine have been enigmatic. As the Seventh Circuit observed:
The commentators have attempted to synthesize from judicial decisions several tests to determine whether the step transaction doctrine is applicable to a ■particular set of circumstances in order to combine a series of steps into one transaction for tax purposes. Unfortunately, these tests are notably abstruse — even for such an abstruse field as tax law. Redding v. Commissioner, 630 F.2d 1169, 1175 (7th Cir.1980), cert. denied, 450 U.S. 913, 101 S.Ct. 1353, 67 L.Ed.2d 338 (1981). Although no test seems to be universally accepted, it is possible to articulate several standards used by the courts in determining when and how to apply the step transaction doctrine. See B. Bittker & J. Eustice, supra, ¶ 14.51 (suggesting that different tests are applicable in different contexts).
The test most often invoked in connection with the application of the step transaction doctrine is the “end result” test. Under this test, “purportedly separate transactions will be amalgamated into a single transaction when it appears that they were really component parts of a single transaction intended from the outset to be taken for the purpose of reaching the ultimate result.” King Enterprises, Inc. v. United States, 418 F.2d 511, 516 (Ct.Cl.1969). As the Fifth Circuit has noted, when cases involve “a series of transactions designed and executed as parts of a unitary plan to achieve an intended result,” the plans will be viewed as a whole “regardless of whether the effect of doing so is imposition of or relief from taxation.” Kanawha Gas & Utilities Co. v. Commissioner, 214 F.2d 685, 691 (5th Cir.1954) (emphasis added). See also Kuper, 533 F.2d at 155-56; Crenshaw, 450 F.2d at 476; Redwing Carriers, Inc. v. Tomlinson, 399 F.2d 652, 658 (5th Cir.1968).
A second test for determining whether the step transaction doctrine applies is la-belled the “interdependence” test. This test focuses on whether “the steps were so interdependent that the legal relations created by one transaction would have been fruitless without a completion of the series.” Paul & Zimet, Step Transactions, in Selected Studies in Federal Taxation 200, 254 (2d Ser.1938), quoted in King Enterprises, 418 F.2d at 516. See also Redding, 630 F.2d at 1177; American Bantam Car Co. v. Commissioner, 11 T.C. 397 (1948), aff’d per curiam, 177 F.2d 513 (3d Cir.1949), cert. denied, 339 U.S. 920, 70 S.Ct. 622, 94 L.Ed. 1344 (1950); 3 J.
