The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” and “Option Awards” columns in the Summary Compensation Table for the applicable year.
(b)
The equity award adjustments for each applicable year include the addition (or subtraction, as applicable) of the following: (i) the year-end fair value of any equity awards granted in the applicable year that are outstanding and unvested as of the end of the year; (ii) the amount of change as of the end of the applicable year (from the end of the prior fiscal year) in fair value of any awards granted in prior years that are outstanding and unvested as of the end of the applicable year; (iii) for awards that are granted and vest in same applicable year, the fair value as of the vesting date; (iv) for awards granted in prior years that vest in the applicable year, the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value; (v) for awards granted in prior years that are determined to fail to meet the applicable vesting conditions during the applicable year, a deduction for the amount equal to the fair value at the end of the prior fiscal year; and (vi) the dollar value of any dividends or other earnings paid on stock or option awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant.

Compensation Actually Paid vs. Total Shareholder Return
Analysis of the Information Presented in the Pay Versus Performance Table
While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay Versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s 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, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.
Compensation Actually Paid and Cumulative TSR
As demonstrated by the following graph, the amount of compensation actually paid to Mr. Shelton and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Shelton) is generally aligned with the Company’s cumulative TSR over the last four completed fiscal years presented in the graph. The graph also compares the Company’s cumulative TSR to the TSR of our peer group. The alignment of compensation actually paid with the Company’s cumulative TSR over the period presented is because a significant portion of the compensation actually paid to our NEOs is comprised of equity awards. As described in more detail in the section “Compensation Discussion and Analysis,” the Company’s executive compensation program is primarily performance-based, for both short-term incentives (annual cash bonuses) and long-term incentives (equity awards).

     
Compensation Actually Paid vs. Net Income
Analysis of the Information Presented in the Pay Versus Performance Table
While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay Versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s 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, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.
Compensation Actually Paid and Net Loss
The amount of compensation actually paid to Mr. Shelton and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Shelton) is compared to the Company’s Net Loss over the last four completed fiscal years presented in the following graph.

     
Compensation Actually Paid vs. Company Selected Measure
Analysis of the Information Presented in the Pay Versus Performance Table
While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay Versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s 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, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.
Compensation Actually Paid and Adjusted EBITDA
The amount of compensation actually paid to Mr. Shelton and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Mr. Shelton) is compared to the Company’s Adjusted EBITDA over the four completed fiscal years in the following graph. As described in more detail in the section “Compensation Discussion and Analysis,” the Company uses Adjusted EBITDA as one of the Base Financial Goals under the Bonus Plan.

Tabular List, Table
Financial Performance Measures
As described in greater detail in “Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a variable pay-for-performance philosophy. The metrics that the Company uses for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our business for our stockholders. The most important financial performance measures used by the Company to link executive compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to the Company’s performance are as follows:
