(1)	The dollar amounts reported are the amounts of total compensation reported in the Summary Compensation Table (“SCT”) for our CEO (“Principal Executive Officer” or “PEO”).

(2)

The dollar amounts reported represent the amount of CAP for the PEO, as computed in accordance with SEC rules. The dollar amounts do not reflect the actual amount of compensation earned by or paid to an executive during the applicable year. CAP includes year-over-year changes in the value of unvested equity awards and therefore may not reflect the value ultimately realized upon vesting of the awards. In accordance with SEC rules, the following adjustments were made to total compensation to determine the CAP:

The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” column in the Summary Compensation Table for the applicable year.

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; and (iii) 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. The amounts deducted or added in calculating the equity award adjustments are as follows:


		Year-End		Year Over Year Change in		Change
