Frost & Sullivan conducted an extensive ratio analysis to rank the companies in the power sector on the basis of different financial and risk management parameters. The ratios of the leading companies ranked within the top 33 percent, indicating that sound financial management plays a key role in the success of a business. "High-performance enterprises diminish uncertainty in demand recovery and risks in customer refinancing through operative measures and customer partnerships," said Frost & Sullivan Business and Financial Services Analyst K. Vinod Cartic. "They follow supply chain management best practices to leverage the economies of scale and minimize raw material price volatility and procurement risks." Successful utilities use commodity derivatives to hedge raw material risks, and also reduce currency exchange fluctuation liabilities through local production. In addition, they employ derivative-based hedging to mitigate the risks of converting receivables and liabilities, as well as purchases and sales, in foreign currencies.
