Promoters of Sterling and Wilson Renewable Energy (SWREL) have injected ₹418 crore into the company to prevent being labeled as defaulters by lenders, according to sources familiar with the matter. The company failed to make payments of ₹135 crore by September 30, and if it had not cleared these dues by December 30, lenders would have been required to categorize it as a non-performing loan (NPA) as per the Reserve Bank of India's guidelines. The ₹418 crore funds, injected on November 30, will be used to settle all outstanding payments.
