Settlement agreement, term	with the United States Department of Justice to civilly resolve the investigation of certain marketing practices. We finalized the settlement in December 2019, and announced it in January 2020 on terms that were consistent with our prior reserve. The settlement amount consisted of the payment to the United States and to various states that joined the action, as well as attorneys’ fees and other costs to the private litigants that filed the suits that the Department of Justice pursued. We also entered into a corporate integrity agreement with the Office of the Inspector General of the U.S. Department of Health and Human Services with accompanying oversight of our sales and marketing practices in the United States for five years.
