• changes in laws and other governmental actions, including monetary, fiscal, and tax policies;
• changes in laws or regulations that adversely affect the ability of electric distribution companies and other purchasers of wholesale electricity to pay their suppliers, including Ameren Missouri;
• the effects of increased competition in the future due to, among other things, deregulation of certain aspects of Ameren Missouri's business at both the state and federal levels, and the implementation of deregulation;

• the impact of current environmental regulations on utilities and power generating companies and new, more stringent or changing requirements, including those related to greenhouse gases, other emissions, cooling water intake structures, coal combustion residuals, and energy efficiency, that are enacted over time and that could limit or terminate the operation of certain of Ameren Missouri's generating units, increase its costs, result in an impairment of its assets, reduce its customers' demand for electricity or natural gas, or otherwise have a negative financial effect;
• the impact of complying with renewable energy portfolio requirements in Missouri;
