Bankrupt Steward Health Care has put all of its 31 U.S. hospitals up for sale, hoping to finalize transactions by the end of the summer to address its $9 billion in total liabilities, its attorneys said at a Tuesday court hearing in Houston.

Steward, which filed for bankruptcy protection on Monday, hopes to keep all of its hospitals open over the long term, Steward attorney Ray Schrock told U.S. Bankruptcy Judge Chris Lopez, who is overseeing the Chapter 11 proceedings.

The privately-owned company closed a hospital in Massachusetts earlier this year, and officials in that state have criticized Steward’s management and its former private equity owners for making short-sighted financial decisions that undermined patients’ care. Massachusetts officials in particular criticized a series of transactions that sold off the company’s real estate and saddled it with long-term rent costs at its hospitals.
