Additional 402(v) Disclosure |  | Represents the total compensation reported for each PEO for each corresponding year in the “Total” column of the Summary Compensation Table. The dollar amounts reported in this column represent the amount of compensation actually paid to each of our PEOs for the applicable fiscal year, computed in accordance with Item 402(v) of Regulation S-K, which do not reflect the compensation actually earned, realized, or received by our PEOs in the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, we have made certain adjustments to each PEO’s total compensation, as reported in the Summary Compensation Table for each year, to determine the compensation actually paid, and a reconciliation of such adjustments is set forth below under “Reconciliation of Summary Compensation Table Total to Compensation Actually Paid for PEOs”. The dollar amounts reported in this column is the average compensation actually paid for our Non-PEO NEOs in each applicable year, computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual amount of compensation earned by or paid to our NEOs during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, we have made certain adjustment to the average of the Non-PEO NEO’s total compensation, as reported in the Summary Compensation Table for each applicable year, and a reconciliation of such adjustment is set forth below under “Reconciliation to Average Summary Compensation Table Total to Average Compensation Actually Paid for Non-PEO NEOs” The amounts reported represent the cumulative total shareholder return (“TSR”) calculated in accordance with Item 201(e) of Regulation S-K, assuming an initial fixed investment of $100, and that all dividends, if any, were reinvested. The metric in this column, the Company’s revenue in the Company’s audited financial statements, in our assessment, represents the most important Company financial performance measure (that is not otherwise disclosed in this table) used to link Compensation Actually Paid to the Company’s performance for our PEOs and Non-PEO NEOs for all years presented. We believe revenue is the most important financial performance measure because as a technology company, our ability to grow and expand our market is a critical element of our success, and our investors and shareholders evaluate our success by the amount of sales we make to customers. Other key financial performance measures linked to executive compensation are described in the section below titled “Financial Performance Measures”. |  |
