The choice of structure partly depends on what the main activities of the organization will be, on how those involved with the bulletin want to regulate decision-making, and on national laws and regulations. Many ISDB drug bulletins have chosen a structure that expresses their non-profit status, such as a foundation or association. Being a non-profit organization does not necessarily mean that the bulletin makes no profits. It means that any profits made by the organization go back towards fulfilling its aims and are not paid out to members or shareholders. As discussed above, a foundation or association may be incorporated, but this is not a requirement in many countries.
