The accuracy of the Company’s assumptions, expectations, beliefs and projections depend on events or conditions that change over time and are thus susceptible to change based on actual experience, new developments and known and unknown risks. The Company gives no assurance that the forward-looking statements will prove to be correct and does not undertake any duty to update them. The Company’s actual future results might differ from the forward-looking statements made in this press release for a variety of reasons, which include the impact that Hurricane Gustav has had on the Company’s assets, employees, customers and business operations. Should one or more of the foregoing reasons materialize, or should the Company’s underlying assumptions prove incorrect, the Company’s actual results may vary materially from those anticipated in its forward-looking statements, and the Company’s business, financial condition and results of operations could be materially and adversely affected.
