Factors that could cause actual results to differ materially from management's projections, forecasts, estimates and expectations may include factors that are beyond the company's ability to control or estimate precisely, such as fluctuations in energy-related commodity prices, including changes in the cost of fuel for our regulated electric business, the timing of the closing dates of acquisitions or divestitures (including any divestiture of our natural gas and oil assets), additional risk exposure associated with the termination of business interruption and offshore property damage insurance related to our exploration and production operations and our inability to replace such insurance on commercially reasonable terms, estimates of future market conditions, estimates of proved and unproved reserves, the company’s ability to meet its natural gas and oil production forecasts, the behavior of other market participants, and the effects of hurricanes on our operations, gas and oil production and realized prices. Other factors include, but are not limited to, weather conditions, governmental regulations, economic conditions in the company's service area, risks of operating businesses in regulated industries that are subject to changing regulatory structures, changes to regulated gas and electric rates collected by Dominion, risks associated with the realignment of our operating assets (including the potential dilutive effect on earnings in the near term and costs associated with any sale of our exploration and production business and the redeployment of proceeds from any sale), changes to rating agency requirements and ratings, changing financial accounting standards, trading counter-party credit risks, risks related to energy trading and marketing, and other uncertainties.
