(1) We define Adjusted EBITDA as income (loss) attributable to stockholders before interest expense (net of interest income), income taxes, depreciation and amortization, non-controlling interests, equity method income, stock compensation, gain or loss on disposal of assets, monitoring and management fees and expenses, realized and unrealized gains or losses on investments, acquisition related expenses, debt extinguishment costs, impairment losses, pension expense, regulatory settlement expense and discontinued operations, net of taxes. Adjusted EBITDA is not intended as a substitute for net income (loss) attributable to stockholders, operating cash flows or other cash flow statement data determined in accordance with accounting principles generally accepted in the United States (“GAAP”). Adjusted EBITDA, as presented, may not be comparable to similarly titled measures of other companies due to varying methods of calculation.
