Carlyle Group is seeking an initial public offering (IPO) of HCR ManorCare, Reuters reports. The company may raise around $500 million through the offering, which will take place in September this year.

Carlyle acquired the healthcare company for $4.9 billion in 2007. In December 2010, it sold most of HCR ManorCare’s real estate assets to HCP in a $6.1 billion sale and leaseback deal.
