In 2002, it was reported that Kerala government have chosen to either restructure or close the loss-making enterprises and has no plan for privatisation. As per CAG report for 2008-2009, Kerala PSUs lack accountability, and needs improvement for imbibing professionalism and efficiency. It showed an incurred loss of 589 crore.
