Bureau of National Affairs
Bureau of National Affairs, Inc., doing business as Bloomberg BNA, is a publisher of specialized online and print news and information for professionals in business and government, headquartered in Arlington, Virginia, USA. It is a wholly owned subsidiary of Bloomberg L.P.. The company reports on legislation, regulations, court decisions and policy.
BNA publishes more than 350 daily, weekly, monthly, and up-to-the-minute news services, in topic areas that include corporate law and business, employee benefits, employment and labor law, environment, health and safety, health care, human resources, intellectual property, litigation, and tax and accounting. BNA’s research and data division offers custom research, data and document retrieval services.
BNA customers are attorneys; accountants and CPAs; lobbyists and policy experts; elected and administrative government officials; administrators and compliance officers in a wide range of industries; and many other decision-makers in the U.S. and abroad. In 2008, BNA offered more than 300 print and electronic information products to the legal and business markets. Completely free of advertising, those products were created by more than 600 Capitol Hill reporters and legal editors and a worldwide network of correspondents. BNA has seven subsidiary companies and a national sales network.
BNA was founded in 1929 by noted newsman David Lawrence as a subsidiary of the United States Daily, now known as U.S. News & World Report. Lawrence chose in 1946 to focus his energies on that other publication and sold BNA to five of his top editors Dean Dinwoodey, John S. Stewart, Ed Donnell, Adolph Magidson, and John Taylor. They in turn opened up ownership to the rest of their colleagues. Until 2011, ownership in BNA was open to employees and retirees only. It was the oldest wholly employee-owned company in the United States.  As of 2013, it is the only major legal publisher that remains American-owned. After more than 75 years based in Washington, DC’s West End, BNA moved five miles, to Arlington, Virginia, in September 2007.
On August 25, 2011, Bloomberg L.P. announced it would be purchasing BNA for an estimated $990 million. Bloomberg offered the employee-owners $39.50 per share. The transaction closed in late September 2011. Since then, Bloomberg has integrated legal materials from BNA into its legal research platform, Bloomberg Law.
