[1] The expected volatility and correlation coefficient of our peer companies for the August 2, 2018 grant date were based on the Russell 2000 Index, which was approved by the Compensation Committee of our board of directors as the benchmark for determining the market-based total shareholder return component. Since the Russell 2000 Index was the only benchmark for determining the market-based total shareholder return component, no ranges were disclosed for these assumptions.
