In June 2015, the U.S. Department of Justice and State of Michigan alleged that Allegiance Health agreed with its horizontal competitors, including Hillsdale Community Health Center, to allocate territories for the marketing of their services in Hillsdale County, Michigan. According to Plaintiffs, the challenged agreement was a customer allocation agreement that resulted in harm to competition and consumers. Allegiance Health was the last Defendant to settle. In early 2018, weeks before trial, Allegiance Health agreed not to communicate with competitors about their respective marketing activities and not to enter into agreements to allocate customers.
