Genesis Healthcare Inc. — an operator of skilled nursing and assisted living facilities — and its subsidiaries have filed for Chapter 11 bankruptcy.

Genesis Healthcare, which operates approximately 175 nursing facilities throughout the U.S., filed for bankruptcy Thursday after struggling to overcome financial burdens including legal costs from personal-injury and wrongful-death claims.

Affiliates of Genesis’ investor ReGen Healthcare, a private equity firm, have entered into a deal to acquire Genesis, according to bankruptcy court documents.
