Enterprise risk management (ERM) refers to the identification, quantification, and management of all of a company's risks within a unified framework. This approach is much more comprehensive than traditional risk management practice, where different types of risk are managed by different people using different tools. The authors evaluate the advantages and disadvantages of ERM and then describe how United Grain Growers (UGG), a major farm service provider in Western Canada, established such an approach. Extensive risk identification and measurement indicated that the volatility of UGG's earnings was driven to a large extent by changes in the volume of its grain shipments, which in turn were principally due to variation in weather. After first considering the use of weather derivatives to hedge the risk, the company ended up purchasing an insurance contract, bundled with its traditional insurance coverage, that pays UGG if its grain volume is unexpectedly low. The potential for moral hazard that can make insurance an expensive proposition was limited by basing payoffs on industry grain shipments rather than the company's shipments. The bundled approach served to expand and integrate UGG's insurance coverage, while eliminating redundant coverage. Besides economizing on insurance costs, another valuable aspect of enterprise risk management is as a source of information about the operations of the firm. By providing managers with a better understanding of their business and events that can undermine the firm's strategic objectives, ERM can lead to better operating decisions as well as a more efficient approach to risk retention and risk transfer.
