Private equity investment funds have been liquidated for more than 6 months. How long it takes for private equity companies to liquidate depends on the actual situation. If the people's court appoints a liquidation group, the liquidation period is 6 months. If the execution of unconfirmed liquidation plan causes losses to the company or creditors, and the company, shareholders, directors, other interested parties of the company or creditors claim that the members of the liquidation group shall be liable for compensation, the people's court shall support it according to law. If the liquidation cannot be completed within six months due to special circumstances, the liquidation group shall apply to the people's court for an extension.
