A total of 55 small and mid-size companies in South Korea, mostly manufacturers and property developers, were found to have bad financial health that may put them under a debt workout program or a court receivership, industry data showed Wednesday. Local banks completed an assessment of 899 companies with loans of below 50 billion won (US$41.9 million) last month and classified them in four categories of A, B, C, D based on their financial soundness.
