General principles.
(1) General principles. In determining whether trade or business from which a particular amount of gross income derives is regularly carried on, within the meaning of section 512, regard must be had to the frequency and continuity with which the activities productive of the income are conducted and the manner in which they are pursued. This requirement must be applied in light of the purpose of the unrelated business income tax to place exempt organization business activities upon the same tax basis as the nonexempt business endeavors with which they compete. Hence, for example, specific business activities of an exempt organization will ordinarily be deemed to be regularly carried on if they manifest a frequency and continuity, and are pursued in a manner, generally similar to comparable commercial activities of nonexempt organizations.
