Section 35.01.01.341 - PRINCIPLES FOR DETERMINING THE EXISTENCE OF A UNITARY BUSINESS: DETERMINATION OF A UNITARY BUSINESSSection 63-3027, Idaho Code
01.In General. Unity can be established under any one (1) of the judicially acceptable tests (Butler Brothers, Edison California Stores, Container, etc.), and cannot be denied merely because another of those tests does not simultaneously apply.02.Significant Flows of Value. A unitary business is characterized by significant flows of value evidenced by factors such as those described in Mobil Oil Corp. v. Vermont, 445 U.S. 425 (1980): functional integration, centralization of management, and economies of scale. These factors provide evidence of whether the business activities operate as an integrated whole or exhibit substantial mutual interdependence. Facts suggesting the presence of the factors mentioned above should be analyzed in combination for their cumulative effect and not in isolation. A particular business operation may be suggestive of one (1) or more of the factors mentioned above.Idaho Admin. Code r. 35.01.01.341
