Pay vs Performance Disclosure [Table] |  |  |  |  |
Pay vs Performance [Table Text Block] |  |  | Pay Versus Performance In accordance with Item 402(v) of SEC Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid (“CAP”) to our principal executive officer (“PEO”) and non-PEO Named Executive Officers (“Non-PEO NEOs”) and certain aspects of our financial performance. The Compensation Committee does not utilize CAP as the basis for making compensation decisions. For further information concerning our compensation philosophy and how we align executive compensation with our performance, please see our Compensation Discussion & Analysis. The following table summarizes compensation paid to our PEO as set forth in our Summary Compensation Table, compensation actually paid to our PEO, average compensation paid to our Non-PEO NE Os as set forth in our Summary Compensation Table, and average compensation actually paid to our Non-PEO NEOs, each as calculated in accordance with SEC rules, and certain Company and peer group performance measures for the periods indicated:

(1) | Mr. Levin succeeded Mr. Trojan as PEO on September 1, 2021. Mr. Trojan served as the PEO for the entirety of fiscal year 2020. Our Non-PEO NEOs for the applicable fiscal years were as follows:
| • |  | FY 2022: Mr. Houdek, Mr. Lynds, Ms. Miller, and Mr. Krakower

(3) | Amounts reported in these columns represent CAP; adjustments were made to the amounts reported in the Summary Compensation Table for the applicable fiscal year. A reconciliation of the adjustments for our PEOs, Messrs. Levin and Trojan, and for the average of the Non-PEO NEOs is set forth in the following table, which describes the adjustments, each of which is prescribed by the SEC rules, to calculate the CAP amounts from Summary Compensation Table amounts.
(4) | Total Shareholder Return (“TSR”) is cumulative for the measurement periods beginning on December 31, 2019 and ending on the last day in fiscal year 2022, 2021 and 2020, respectively, calculated in accordance with Item 201(e) of Regulation S-K.

(6) | We have determined that operating income is the financial performance measure that, in our assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used to link compensation actually paid to our named executive officers, for the most recently completed fiscal year, to company performance.
