The table below represents some of our critical metrics (in thousands except for per ton data):

--------------------------------

EBITDA, adjusted EBITDA, and adjusted free cash flow should not be considered alternatives to net income, income from operations, cash flows from operating activities or any other measure of financial performance presented in accordance with GAAP.  Our method of computing EBITDA, adjusted EBITDA, and adjusted free cash flow may not be the same method used to compute similar measures reported by other companies.

Management believes that the presentation of such additional financial measures provides useful information to investors regarding our performance and results of operations because these measures, when used in conjunction with related GAAP financial measures, (i) provide additional information about our core operating performance and ability to generate and distribute cash flow, (ii) provide investors with the financial and analytical framework upon which management bases financial, operation, compensation, and planning decisions, and (iii) present measurements that investors, rating agencies, and debt holders have indicated are useful in assessing our results.
