KKR & Co., Davidson Kempner Capital Management LP and York Capital Management Global Advisors LLC are among the most heavily invested bondholders in Quorum Health Corp., the bankrupt hospital operator that plans to turn itself over to creditors, WSJ Pro Bankruptcy reported. Five investment firms belong to a bondholder committee in the chapter 11 reorganization of the publicly traded company, according to court papers filed on Thursday. Quorum entered bankruptcy with an agreement in hand with most of its lenders and bondholders that would help it cut its roughly $1.3 billion in debt by about $500 million, pending approval from the U.S. Bankruptcy Court in Wilmington, Del. KKR owns or manages funds that hold Quorum bonds with a face value of $124.9 million. Davidson Kempner and York Capital own $114.2 million and $40 million in Quorum bonds, respectively, according to court papers.
