Additional 402(v) Disclosure [Text Block]

The dollar amounts reported represent the amount of "compensation actually paid," as calculated in accordance with SEC rules. The dollar amounts do not reflect the actual amounts of compensation paid to our executives during the applicable year. In accordance with SEC rules, certain adjustments were made to the "Summary Compensation Table" total compensation to determine the amount of "compensation actually paid," including adding (i) the year-end fair value of equity awards granted during the reported year, and (ii) the change in the fair value of equity awards that were unvested at the end of the prior year, measured through the date the awards vested or were forfeited, or through the end of the reported fiscal year. For purposes of calculating "compensation actually paid," the fair value of equity awards is calculated in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 (FASB ASC Topic 718) using the same assumption methodologies used to calculate the grant date fair value of awards for purposes of the "Summary Compensation Table" (see page 51 for additional information).
