29 CFR § 779.213 - What is a common business purpose.
Generally, the term “common business purpose” will encompass activities whether performed by one person or by more than one person, or corporation, or other business organization, which are directed to the same business objective or to similar objectives in which the group has an interest. The scope of the term “enterprise” encompasses a single business entity as well as a unified business system which performs related activities for a common business purpose. What is a “common business purpose” in any particular case involves a practical judgment based on the facts in the light of the statutory provisions and the legislative intent. The answer ordinarily will be readily apparent from the facts. The facts may show that the activities are related to a single business objective or that they are so operated or controlled as to form a part of a unified business system which is directed to a single business objective. In such cases, it will follow that they are performed for a common business purpose. Where, however, the facts show that the activities are not performed as a part of such enterprise but for an entirely separate and unrelated business, they will be considered performed for a different business purpose and will not be a part of that enterprise. The application of these principles is considered in more detail in part 776 of this chapter.
