Non-GAAP Financial Information This presentation may use the non-gaap financial measures of free cash flow, earnings per share (EPS) on an ongoing basis, EBIT and EBITDA on an ongoing basis, EBITDA on an as reported basis, and net debt. We define free cash flow as the total of cash flows from operating activities and investing activities. A non-gaap EPS financial measure, which we refer to as ongoing EPS, excludes certain after-tax items that we do not consider part of ongoing operations, which are identified in the reconciliation. EBIT is defined as earnings (loss) before interest and taxes, ongoing EBITDA is defined as earnings (loss) before interest, taxes, depreciation and amortization and excludes certain after-tax items that we do not consider part of ongoing operations, as defined in the reconciliation, and as reported EBITDA is defined as earnings (loss) before interest, taxes, depreciation and amortization. Earnings (loss) is intended to mean net income (loss) attributable to Monsanto Company as presented in the Statements of Consolidated Operations under GAAP. Net debt is defined as the sum of both short-term debt and long-term debt, less cash and cash equivalents. Our presentation of non-gaap financial measures is intended to supplement investors understanding of our operating performance, not replace net income (loss) attributable to Monsanto Company, cash flows, financial position, or comprehensive income (loss), as determined in accordance with GAAP. Furthermore, these non-gaap financial measures may not be comparable to similar measures used by other companies. The non-gaap financial measures used in this presentation are reconciled to the most directly comparable financial measures calculated and presented in accordance with GAAP.
