A group of fifty independent physicians in a community decide to form an independent physician association ("IPA") for purposes of organizing a provider network and competing for managed care contracts and value-based arrangements. Each physician member will pay dues to participate in the network but will maintain a separate medical practice. The IPA will function only as a trade association. The IPA will not engage in the practice of medicine or have any other business purpose except for entering into payor agreements for the benefit of the IPA's physician participants, and the IPA will cover its administrative costs through the physician member dues and payments to the IPA from value-based arrangements. 4.2.1 Describe two different forms of business organization that are suitable for this purpose and what actions must be taken and documents that must be prepared to complete the organizational process. Please be specific. 4.2.2 Which form would you recommend and why? Be sure to describe your analytical criteria
