Tabular List, Table | Financial Performance Measures As described in the Compensation Philosophy and Objectives section contained in this Proxy Statement, our executive compensation program is designed to directly link a significant portion of the compensation of our named executive officers to individual performance and our overall performance, with the goals of aligning our executives’ long-term interests with those of our stockholders and attracting, retaining and motivating key executives who are essential to the implementation of our strategic growth and development strategy. Our Compensation Committee evaluates individual and company performance in a qualitative fashion and does not utilize specific financial or operating performance goals or targets in setting executive compensation, but it considers the following financial measures to be the most important financial measures used by the Company to link CAP for the Company’s named executive officers for the most recently completed fiscal year, to Company performance:
• | Adjusted income before income taxes.
• | Adjusted pre-tax profit margin.
• | 3-year adjusted net revenue growth.
