The prior page includes company information that does not conform with generally accepted accounting principles (GAAP). Management believes the use of these non-GAAP measures is meaningful to investors because they provide insight with respect to operating results of the company and additional metrics for use in comparison to competitors. These measures should not be viewed as an alternative to GAAP measures of performance. Furthermore, these measures may not be consistent with similar measures used by other companies. This data should be read in conjunction with previously published company reports on Forms 10-K, 10-Q, and 8-K. These reports are available on the Investor Center of www.dupont.com. Reconciliations of non-GAAP measures to GAAP are also included herein.
