Rural/Metro Corp., a nationwide ambulance operator that serves that Buffalo area, has filed for Chapter 11 bankruptcy protection.
Bloomberg reports that the company will continue to provide emergency services.
Rural/Metro, which is based in Arizona, missed a mid-July interest payment on unsecured bonds. That triggered a downgrade in its Standard and Poor's debt and credit ratings.
The company listed assets and debts of more than $500 million apiece in papers filed with the U.S. Bankruptcy Court in Delaware.
