In 2015, private equity firm KKR invested in CCM, taking a majority stake for $258 million. But relations soured last year when CCM sued KKR and other investors for fraud and gross negligence, alleging the latter had made "a deliberate attempt ... to intentionally make false and material misleading statements through the company's 2019 financials by overstating inventory values in order to conceal the fraud and mismanagement of the company. These actions ultimately led to the company restructuring the plaintiff's equity value to pennies on the dollar."
