Note regarding non-GAAP financial measures The company reports its financial results in accordance with U.S. generally accepted accounting principles (GAAP). Management believes that EBITDA, adjusted EBITDA, adjusted net earnings, adjusted net earnings per diluted share, controllable cost of sales, controllable cost of sales per ton, and, on a segment basis, adjusted gross margin and adjusted gross margin per nutrient ton, which are non-GAAP financial measures, provide additional meaningful information regarding the company's performance and financial strength. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the company's reported results prepared in accordance with GAAP. In addition, because not all companies use identical calculations, EBITDA, adjusted EBITDA, adjusted net earnings, adjusted net earnings per diluted share, controllable cost of sales, controllable cost of sales per ton, adjusted gross margin, and adjusted gross margin per nutrient ton included in this presentation may not be comparable to similarly titled measures of other companies. Reconciliations of EBITDA, adjusted EBITDA, adjusted net earnings, adjusted net earnings per diluted share, controllable cost of sales, controllable cost of sales per ton, adjusted gross margin, and adjusted gross margin per nutrient ton to the most directly comparable GAAP measures are provided in the tables accompanying this presentation. EBITDA is defined as net earnings/(loss) attributable to common stockholders plus interest expense (income)-net, income taxes, and depreciation and amortization. Other adjustments include the elimination of loan fee amortization that is included in both interest and amortization, and the portion of depreciation that is included in noncontrolling interests. The company has presented EBITDA because management uses the measure to track performance and believes that it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in the industry. Adjusted EBITDA is defined as EBITDA adjusted with the selected items included in EBITDA as summarized in the tables accompanying this presentation. The company has presented adjusted EBITDA because management uses adjusted EBITDA, and believes it is useful to investors, as a supplemental financial measure in the comparison of year-over-year performance. Adjusted net earnings is defined as net (loss) earnings attributable to common stockholders adjusted with the impacts of the selected items included in net (loss) earnings as summarized in the tables accompanying this presentation. The company has presented adjusted net earnings and adjusted net earnings per diluted share because management uses these measures, and believes they are useful to investors, as supplemental financial measures in the comparison of year-over-year performance. Adjusted gross margin is defined as gross margin excluding depreciation and amortization and unrealized net mark-to-market (gain) loss on natural gas derivatives. The company has presented adjusted gross margin because management uses this measure, and believes it is useful to investors, as a supplemental financial measure in the comparison of year-over-year performance. Controllable cost of sales is defined as cost of sales adjusted for natural gas costs, realized and unrealized losses (gains) on natural gas derivatives, and depreciation and amortization. The company has presented controllable cost of sales and controllable cost of sales per ton because management uses these measures, and believes they are useful to investors, as supplemental financial measures in the comparison of year-over-year performance.
