Nortek Filing for Bankruptcy Protection

NTK Holdings Inc. (Nortek), a Providence, R.I.-based maker of ventilation, air conditioning and heating products, said that it will file for bankruptcy protection as part of a restructuring agreement with its lenders. THL Partners acquired NTK from Kelso & Co. in 2004, and held a 66.48% equity stake as of late 2007, when NTK canceled a proposed $690 million IPO.
