Thompson Publishing files for Chapter 11

SAN FRANCISCO — Thompson Publishing Group Inc., whose books focus on regulatory compliance advice for professionals in health care, human resources and other industries, has filed for Chapter 11 bankruptcy protection.

The company’s filing Tuesday in U.S. Bankruptcy Court for the District of Delaware lists $10 million to $50 million in assets and $100 million to $500 million in estimated liabilities.

Its biggest equity stakeholder is listed as Avista Capital Partners, a private equity firm.

Avista was in the news Tuesday for another reason: It agreed to pay $780 million to buy a division of Clorox Co. that makes the car-care brands Armor All and STP.
