Principal purpose or functions.
Principal purpose or functions. An organization must be organized for the principal purpose of engaging primarily in the conduct of medical research in order to be an organization meeting the requirements of this paragraph (d)(2). An organization will normally be considered to be so organized if it is expressly organized for the purpose of conducting medical research and is actually engaged primarily in the conduct of medical research. Other facts and circumstances, however, may indicate that an organization does not meet the principal purpose requirement of this paragraph (d)(2)(iv) even where its governing instrument so expressly provides. An organization that otherwise meets all of the requirements of this paragraph (d)(2) (including this paragraph (d)(2)(iv)) to qualify as a medical research organization will not fail to so qualify solely because its governing instrument does not specifically state that its principal purpose is to conduct medical research.
