Financial Performance Measures

As described in greater detail in the section entitled “Compensation Discussion and Analysis,” our executive compensation program reflects a variable compensation philosophy. The metrics that we use for both our annual cash incentive awards and long-term, equity-based incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our stockholders. The most important financial performance measures used by the Company to link “compensation actually paid” to the Company’s NEOs, for the most recently completed fiscal year, to the Company’s performance are as follows:

• earnings per share;

• revenues; and

• income before income taxes.
