Use of Non - GAAP Measures 16 This presentation includes disclosures regarding “EBITDA,” “adjusted EBITDA,” and “total net debt to last twelve month adjusted EBITDA coverage ratio,” all of which are non - GAAP financial measures and described in this section as not being in compliance with Regulation S - X. Accordingly, they should not be construed as alternatives to net cash from operating or investing activities, cash and cash equivalents, cash flows from operations, net income or net income per share as defined by GAAP and are not, on their own, necessarily indicative of cash available to fund cash needs as determined in accordance with GAAP. In addition, not all companies use identical calculations, and the non - GAAP financial measures may not be comparable to other similarly titled measures of other companies. A reconciliation of the differences between these non - GAAP financial measures and the most directly comparable financial measures presented in accordance with GAAP is included in the tables that follow. Adjusted EBITDA is comprised of EBITDA, adjusted for certain items as permitted or required by the lenders under our credit agreement in place at the end of each quarter in the periods presented. The tables that follow include an explanation of how adjusted EBITDA is calculated for each of the periods presented with the reconciliation to net income. EBITDA is defined as net earnings before interest expense, income taxes, depreciation and amortization on a historical basis. Management believes adjusted EBITDA is useful as a means to evaluate our ability to fund our estimated uses of cash (including interest on our debt). In addition, we have presented adjusted EBITDA, in the past because they are frequently used by investors, securities analysts and other interested parties in the evaluation of companies in our industry, and management believes presenting them here provides a measure of consistency in our financial reporting. Adjusted EBITDA is also a component of the restrictive covenants and financial ratios contained in our credit agreement that requires us to maintain compliance with these covenants and limit certain activities, such as our ability to incur debt. The definitions in these covenants and ratios are based on adjusted EBITDA. We present the related “total net debt to last twelve month adjusted EBITDA coverage ratio” principally to put other non - GAAP measures in context and facilitate comparisons by investors, security analysts and others; this ratio differs in certain respects from the similar ratio used in our credit agreement. These measures differ in certain respects from the ratios used in our senior notes indenture. These non - GAAP financial measures have certain shortcomings. In particular, adjusted EBITDA does not represent the residual cash flows available for discretionary expenditures, since items such as debt repayment and interest payments are not deducted from such measure. In addition, the ratio of total net debt to last twelve month adjusted EBITDA is subject to the risk that we may not be able to use the cash on the balance sheet to reduce our debt on a dollar - for - dollar basis. Management believes these ratios are useful as a means to evaluate our ability to incur additional indebtedness in the future. We present the non - GAAP measures adjusted diluted net income per share and adjusted diluted net income attributable to common stockholders because our net income and net income per share are regularly affected by items that occur at irregular intervals or are non - cash items. We believe that disclosing these measures assists investors, securities analysts and other interested parties in evaluating both our company over time and the relative performance of the companies in our industry.

Other, net includes income attributable to non - controlling interests, cash distributions less equity earnings from our investments, dividend income, acquisition and non - recurring related costs, gain on the extinguishment of debt and certain miscellaneous items. 3. Represents compensation expenses in connection with our Restricted Share Plan, which because of the non - cash nature of the expenses are excluded from adjusted EBITDA. To enhance the information in our outlook with respect to non - GAAP metrics, we are providing a range for certain GAAP measures that are components of the reconciliation of the non - GAAP metrics. The provision of these ranges is in no way meant to indicate that we are explicitly or implicitly providing an outlook on those GAAP components of the reconciliation. In order to reconcile the non - GAAP financial metric to GAAP, we have used ranges for the GAAP components that arithmetically add up to the non - GAAP financial metric. While we feel reasonably comfortable about the outlook for the non - GAAP financial metrics, we fully expect that the ranges used for the GAAP components will vary from actual results. We will consider our outlook of non - GAAP financial metrics to be accurate if the specific non - GAAP metric is met or exceeded, even if the GAAP components of the reconciliation are different from those provided in an earlier reconciliation. 12 Months Ended December 31, 2019 Low High Net loss $ ( 22 ) $ ( 12 ) Add (subtract): Income tax benefit ( 11 ) ( 6 ) Interest expense, net 138 133 Depreciation and amortization 390 385 EBITDA 495 500 Adjustments to EBITDA (1): Other, net (2) 12 12 Pension/OPEB expense 6 6 Non - cash compensation (3) 7 7 Adjusted EBITDA $ 520 $ 525
