Pay vs Performance Disclosure [Table] |  |  |  |  |
Pay vs Performance [Table Text Block] |  | ## Pay versus Performance Pursuant to the Dodd-Frank Act and Item 402(v) of Regulation S-K, we are required to provide the following information regarding the relationship between executive compensation paid to our named executive officers and Vericel’s financial performance for each of the last four completed calendar years. In determining the Compensation Actually Paid (or “CAP”) to our Principal Executive Officer, who is our CEO, and our other named executive officers, we are required to make various adjustments to the amounts that have been previously reported in the Summary Compensation Table, as summarized below. The CAP amounts reflected in the table below do not reflect the actual amount of compensation earned by or paid to our named executive officers during the applicable year. For information regarding decisions made by our Compensation Committee with respect to executive compensation, refer to the “Compensation Discussion and Analysis” section of this Proxy Statement.
