In accordance with Item 402(v) of Regulation S-K, we are providing the following graphical descriptions of the relationships between information presented in the Pay Versus Performance table on compensation actually paid and each of total shareholder return (“TSR”) or net income (loss). We do not utilize TSR and net income (loss) in our executive compensation program. As described in more detail above in the section “Compensation Discussion and Analysis,” part of the compensation our named executive officers are eligible to receive consists of annual cash bonuses that are designed to provide appropriate incentives to our executives to achieve defined annual corporate goals and to reward our executives for achievement towards these goals. Additionally, we view premium-priced stock options, which are part of our executive compensation program, as related to company performance although not directly tied to TSR, because they provide value only if the market price of our common stock increases, and if the executive officer continues in our employment over the vesting period. These stock option awards intend to align our executive officers’ interests with those of our stockholders by providing a continuing financial incentive to maximize long-term value for our stockholders and by encouraging our executive officers to continue in our employment for the long-term.
