The following information is included for convenience only. Generally, a non-GAAP financial measure is a numerical measure of a company's performance, financial position or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles ("GAAP"). EBITDA, adjusted EBITDA, cash flow prior to working capital changes, cash flow, cash flow return, net debt, net debt to capital and consolidated net sales are not measures of financial performance (nor do they have standardized meanings) under either Canadian GAAP or US GAAP. In evaluating these measures, investors should consider that the methodology applied in calculating such measures may differ among companies and analysts.
The company uses both GAAP and certain non-GAAP measures to assess performance. Management believes these non-GAAP measures provide useful supplemental information to investors in order that they may evaluate PotashCorp's financial performance using the same measures as management. Management believes that, as a result, the investor is afforded greater transparency in assessing the financial performance of the company. These non-GAAP financial measures should not be considered as a substitute for, nor superior to, measures of financial performance prepared in accordance with GAAP.
