Preferred provider organization
In health insurance in the United States, a preferred provider organization (PPO), sometimes referred to as a participating provider organization or preferred provider option, is a managed care organization of medical doctors, hospitals, and other health care providers who have agreed with an insurer or a third-party administrator to provide health care at reduced rates to the insurer's or administrator's clients.
Alternative public offering
There are two parts that comprise an APO: the reverse merger and the PIPE. In the reverse merger, the private company becomes public by merging with or being acquired by a public “shell” company. The shell company is a public company that has no assets or liabilities. When the private company and public shell merge, the combined entity thereafter trades under the previously private company’s name rather than the shell company’s name as it did before.
