Forward-looking statements represent our intentions, plans, expectations, assumptions, and beliefs about future events. This release includes forward-looking statements concerning the expectation that the closing conditions will be satisfied and the Tres Palacios acquisition will close, the accretion expectations as a result of Tres Palacios, the availability and timing of any expansion possibilities at Tres Palacios, the expectation that the acquisition will be funded by a combination of debt and equity, the anticipated future storage capacity at storage projects as well as future demand for such capacity, and the timing of the pending simplification transaction with Inergy Holdings, L.P.

Should one or more of these risks or uncertainties materialize or any underlying assumption proves incorrect, actual results may vary materially from those anticipated, estimated, or projected. Among the key factors that could cause actual results to differ materially from those referred to in the forward-looking statements are: weather conditions that vary significantly from historically normal conditions, the demand for high deliverability natural gas storage capacity in the Northeast and in Texas, the general level of natural gas and other hydrocarbon product demand, the availability of natural gas, the price of natural gas to the consumer compared to the price of alternative and competing fuels, our ability to successfully implement our business plan for midstream expansion, our ability to generate available cash for distribution to unitholders, the outcome of certificate and rate decisions issued by the Federal Energy Regulatory Commission, and the costs and effects of legal, regulatory, and administrative proceedings against us or which may be brought against us.
