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 2017年12月31日, 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.

Additional Criteria • Total heat release (MJ/m²) • pHRR (kW/m²) • Time of Ignition (s) • Smoke production • Acidity • Flaming droplets This example demonstrates the need to consider the complete cable design, as using XLPE for the insulation layer would not give the required Euroclass.

The following chart compares cumulative TSR on our common shares against the cumulative total return of the S&P 500 Index and the S&P Mid Cap Chemicals Index for the five-year period 2010年12月31日 to 2015年12月31日, assuming in each case a fixed investment of $100 and reinvestment of all dividends. Our performance has exceeded the S&P 500 Index as well as the S&P Mid Cap Chemicals Index. The $1 million deduction limit generally does not apply to compensation that satisfies Section 162(m)’s requirements for qualified performance-based compensation.
