The following table compares cumulative total shareholder return (“TSR”) on our common shares against the cumulative total return of the S&P 500 Index and the S&P Mid Cap Chemicals Index over one-, three- and five-year periods ending December 31, 2017, assuming in each case a fixed investment of $100 and reinvestment of all dividends. Over a three-year time period, our TSR performance was less than the S&P 500 Index and the S&P Mid Cap Chemicals Index, primarily due to weaker performance from our DSS segment, which we subsequently divested in July 2017. These investments ultimately paid off, as 1-year TSR performance for 2017 exceeded that of the S&P indices and our peers.
