When classifying a joint arrangement, the criteria to be considered include the rights and obligations that each party has with respect to the assets and liabilities of the arrangement. The correct classification depends on whether the parties have rights to the assets and obligations for the liabilities, rather than just distribution terms or the legal form of the separate vehicle. Therefore, the factor that is not considered when classifying a joint arrangement as a joint venture or a joint operation is:
A. Whether the terms of the contractual arrangement specify that annual distributions to the parties are required.
