The chart illustrates the cumulative total return of the Company's stock following completion of the Merger based on a presumed investment of $100 on September 1, 2017 and a presumption that all dividends were reinvested. The historical stock prices of DuPont presented in the chart have been adjusted to reflect the impact of the Distributions and the Reverse Stock Split. The Company elected to display the closing price on May 31, 2019, the day preceding the Corteva Distribution, in order to provide the reader a more useful baseline for the Company's performance as a specialty products company after consummation of the Distributions. The chart does not reflect the Company's forecast of future financial performance.
