Incentive-plan design — the Compensation Discussion & Analysis

The compensation committee targets a general competitive position based on independent third-party benchmark analytics to inform the mix of base salary, bonus, and long-term incentives. The program is designed to motivate employees to achieve short- and long-term results in the best interests of stockholders, align executive interests with stockholders through equity grants, and promote retention.
