A Virginia-based insurance broker agreed to pay more than $30 million to settle allegations it steered clients to preferred insurance companies and shared rebates with one of the nation’s largest obstetrician and gynecologist management companies.

Hilb Rogal & Hobbs Co., the nation’s eighth-largest insurance broker, announced Wednesday it had reached an agreement with Connecticut Attorney General Richard Blumenthal and the state’s insurance agency. The company was not required to admit criminal wrongdoing in the case, and its attorneys admitted only that state investigators were prepared to bring allegations.
