| Adjustment To PEO Compensation, Footnote [Text Block] | The amounts reported represent the amount of CAP to Mr. Prince for the corresponding fiscal year, as computed in accordance with SEC rules as further described below. These amounts do not reflect the actual amount of compensation earned by or paid to Mr. Prince during the applicable year. In accordance with Item 402(v) of Regulation S-K under the Securities Act, the following adjustments were made to Mr. Prince’s total compensation for each year to determine the CAP: Year Reported Less: Reported Add: Equity Compensation Actually Paid to PEO ($) 2022 599,731 — (124,400,047) (123,800,316) 2021 400,000 — 133,249,996 133,649,996 2020 434,722 — 182,620,846 183,055,568 _______________________ (a) The grant date fair value of equity awards represents the total of the amounts reported in the “Stock Awards” and “Option Awards” columns in the 2022 Summary Compensation Table for the applicable year. For more information, see the section titled “ 2022 Summary Compensation Table .” We have never provided pension benefits to our NEOs; therefore, no adjustments to the 2022 Summary Compensation Table total for changes in pension values are necessary. (b) 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; (iii) for awards that are granted and vest in the same applicable year, the fair value as of the vesting date; (iv) 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; (v) for awards granted in prior years that are determined to fail to meet the applicable vesting conditions during the applicable year, a deduction for the amount equal to the fair value at the end of the prior fiscal year; and (vi) the dollar value of any dividends or other earnings paid on stock or option awards in the applicable year prior to the vesting date that are not otherwise reflected in the fair value of such award or included in any other component of total compensation for the applicable year. The valuation assumptions used to calculate the fair value were updated as of each measurement date and will differ from those disclosed as of the grant date. The methodology used to develop the valuation assumptions as of each applicable measurement date is consistent with those disclosed at the time of grant. The amounts deducted or added in calculating the equity award adjustments are as follows: Year Year-End Fair Value of Equity Awards Granted in the Year and that are Outstanding and Unvested ($) Year-over-Year Change in Fair Value of Equity Awards Granted in Prior Years that are Outstanding and Unvested ($) Fair Value as of Vesting Date of Equity Awards Granted and Vested in the Year ($) Year-over-Year Change in Fair Value of Equity Awards Granted in Prior Years that Vested in the Year ($) Prior Year-End Fair Value of Equity Awards that Failed to Meet Vesting Conditions in the Year ($) Value of Dividends or other Earnings Paid on Equity Awards not Otherwise Reflected in Fair Value or Total Compensation ($) Total 2022 — (64,717,501) — (59,682,546) — — (124,400,047) 2021 — 97,142,504 — 36,107,493 — — 133,249,996 2020 — 162,057,497 — 20,563,348 — — 182,620,846 | | | |

| Tabular List [Table Text Block] | The following table includes the three financial performance measures that we believe represent our most important financial performance measures we used to link CAP to company performance. As described in greater detail in the section titled “ Compensation Discussion and Analysis ,” the company’s executive compensation program reflects a pay-for-performance philosophy. The most important financial performance measure used by the company to link executive compensation actually paid to the named executive officers, for the most recently completed fiscal year, to the company’s performance is revenue. 2022 Financial Performance Measures Revenue Gross Margin Stock Price | | | |

The company has not paid dividends historically. (8) The amounts reported represent our revenue, as reflected in the company’s audited financial statements for the applicable year as included in our 2022 Annual Report. While we use several financial performance measures for purposes of our compensation programs, we have determined that revenue 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 by the company to link CAP to the named executive officers, for the most recently completed fiscal year, to the company’s performance. | | | |
