The Company is furnishing the presentation as Exhibit 99.1 hereto and has also made the presentation materials available on its website at www.sug.com. The presentation materials attached hereto 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 attached presentation, the Company uses pro forma earnings before interest, taxes, depreciation and amortization (EBITDA), a non-GAAP financial measure, as the performance measure 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 generally accepted accounting principles (GAAP).

The Company defines EBITDA as net earnings (loss) available for common shareholders, adjusted for: (i) items that do not impact earnings (loss) from continuing operations, such as extraordinary items, discontinued operations and the impact of accounting changes; (ii) income taxes; (iii) interest; (iv) depreciation; (v) amortization and (vi) dividends on preferred stock. EBITDA may not be comparable to measures used by other companies.
