Additional 402(v) Disclosure

Cumulative TSR is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between our share price at the end and the beginning of the measurement period by our share price at the beginning of the measurement period.The dollar amounts reported represent the amount of net income reflected in our audited financial statements for the applicable year.

8.While we use numerous financial and non-financial performance measures for the purpose of evaluating performance for our compensation programs, for the most recently completed fiscal year, we have determined that revenue growth is the financial performance measure that, in our assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) linking compensation actually paid to company performance. The dollar amounts reported in this column represent the amount of revenue reflected in our audited financial statements for the applicable year.

Financial Performance Measures

As described in greater detail in “Executive Compensation – Compensation Discussion and Analysis,” our executive compensation program reflects a pay-for-performance philosophy. The compensation and talent committee determines financial performance measures for our Bonus Plan and equity incentive awards to incentivize our named executive officers to align payouts with our financial success and creation of long-term value for our stockholders. For the most recently completed fiscal year, the most important financial performance measures used by us to link executive compensation actually paid to our named executive officers to our performance are as follows:

Analysis of the Information Presented in the Pay versus Performance Table

As described in more detail in the section “Executive Compensation – Compensation Discussion and Analysis,” our executive compensation program reflects a pay-for-performance philosophy. While we utilize several performance measures to align executive compensation with our performance, all of those measures are not presented in the Pay versus Performance table. Moreover, we generally seek to incentivize long-term performance and, therefore, do not specifically align our performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, we are providing the following descriptions of the relationships between the information presented in the Pay versus Performance table.
