Item 7.01 Regulation FD Disclosure

Southern Union Company (the “Company”) today posted an investor presentation to its web-site related to its 2011 financial outlook. The presentation focuses on an overview of the Company’s operations, 2011 financial and operational guidance and proposed organic growth projects.

The Company is furnishing the updated presentation as Exhibit 99.1. The 2011 outlook information presented herein under Item 7.01 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such a filing.

In the presentation, the Company uses earnings before interest, taxes, depreciation and amortization (EBITDA) and adjusted EBITDA, as well as adjusted earnings per share, all non-GAAP financial measures, as performance measures to evaluate segment performance. As defined in Regulation G, "Conditions for Use of Non-GAAP Financial Measures," a non-GAAP financial measure is a numerical measure of a company's historical or future performance, financial position or cash flow that excludes (includes) amounts, or is subject to adjustments that have the effect of excluding (including) amounts, that are included (excluded) in the most directly comparable measure calculated and presented in accordance with GAAP. The Company provides a full Regulation G reconciliation of the non-GAAP financial measures used to evaluate Company and segment performance in the financial outlook materials.

EBITDA, adjusted EBITDA and adjusted net earnings per share may not be comparable to measures used by other companies.  Additionally, EBITDA, adjusted EBITDA and adjusted net earnings per share should be considered in conjunction with net earnings and other performance measures such as operating income or operating cash flow.
