| Pay vs Performance [Table Text Block] | Pay Versus Performance As required by Section 952(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid and our financial performance for each of the last three completed fiscal years. In determining the “compensation actually paid” to our NEOs, we are required to make various adjustments to amounts that have been previously reported in the Summary Compensation Table in previous years, as the SEC’s valuation methods for this disclosure differ from those required in the Summary Compensation Table. For our NEOs other than our Principal Executive Officer (our “PEO”), compensation is reported as an average.

The dollar amounts reported in this column are the amounts of total compensation reported for Mr. Miller in the “Total” column of the Summary Compensation Table in the applicable fiscal year. (2) Glenn Lurie served as our PEO from November 2017 to September 2020. The dollar amounts reported in this column are the amounts of total compensation reported for Mr. Miller in the “Total” column of the Summary Compensation Table in the applicable fiscal year. (3) In accordance with SEC rules, the following adjustments were made to determine the compensation actually paid to our PEO during fiscal years 2022, 2021 and 2020, which consisted solely of adjustments to the PEO’s equity awards: 2022 2021 2020 First PEO First PEO First PEO Second PEO Reported Summary Compensation Table Total ($) 2,756,085 4,647,924 1,415,614 4,572,180 Reported Summary Compensation Table Stock Award Value ($) -143,856 -3,293,156 -600,000 -3,000,000 Reported Summary Compensation Table Option Award Value ($) -485,229 -603,768 -113,857 -1,000,000 Change in fair value of Equity granted prior to covered year that Vested during covered FY ($) +1,152,298 -994,456 -632,989 -18,462,100 Change in fair value of Unvested Equity at FYE granted prior to the covered FY ($) -4,036,294 -87,114 -261,839 Fair value of Unvested Equity at FYE granted during the covered FY ($) +1,623,195 +3,273,593 +737,432 0 Fair value of Awards that were Forfeited during the Applicable FY ($) 0 0 0 -33,404,444 Compensation Actually Paid ($) -17,242,931 -1,006,157 719,085 -51,556,202 (4) For performance-based restricted cash units, the grant date fair value of awards used for Summary Compensation Table calculations assumes target performance. To determine the year-end fair values used in the Compensation Actually Paid calculations, we have updated the performance expectations to reflect the latest performance estimates for unvested and outstanding awards at each fiscal year end date. For stock options awards, updated market input assumptions (stock price, risk free interest rate, volatility, expected term, and future dividend yield expectations) have been used to determine the fair values of outstanding awards as of the identified vesting dates and the relevant fiscal year end dates using the Black Scholes Merton option pricing model. (5) The non-PEO NEOs for each year reported are as follows: Year NEOs included in Average 2022 Louis Ferraro, Christopher Hill, Patrick Doran, Christina Gabrys, Taylor Greenwald 2021 Taylor Greenwald, Christopher Hill, Patrick Doran, Louis Ferraro, Ronald Prague, David Clark 2020 David Clark, Christopher Hill, Patrick Doran, Ronald Prague, Mary Clark The dollar amounts reported in this column represent the average of the amounts reported for the non-PEO NEOs in the “Total” column of the Summary Compensation Table in the applicable fiscal year. (6) In accordance with SEC rules, the following adjustments were made to determine the compensation actually paid on average to our non-PEO NEOs during fiscal years 2022, 2021 and 2020, which consisted solely of adjustments to the non-PEO NEOs’ equity awards: 2022 2021 2020 Avg NEO Avg NEO Avg NEO Reported Summary Compensation Table Total ($) 1,143,767 1,492,555 1,414,545 Reported Summary Compensation Table Stock Award Value ($) -459,896 -697,541 -552,000 Reported Summary Compensation Table Option Award Value ($) -153,299 -151,601 -234,804 Change in fair value of Equity granted prior to covered year that Vested during covered FY ($) +115,754 -137,824 -1,995,008 Change in fair value of Unvested Equity at FYE granted prior to the covered FY ($) -8,206,868 -509,989 -66,998 Fair value of Unvested Equity at FYE granted during the covered FY ($) +491,952 +1,639,896 +542,938 Fair value of Awards that were Forfeited during the Applicable FY ($) 0 0 -1,836,937 Compensation Actually Paid ($) -7,068,589 1,635,495 -2,728,264 (7) Calculated in the same manner as required under Item 201(e) of Reg S-K, measuring the TSR from the market close on the last trading day before the earliest fiscal year in table through to and including the end of the fiscal year for which TSR is calculated.
