Redeemable Series A-1 Preferred Stock	16. REDEEMABLE SERIES A-1 PREFERRED STOCK On October 19, 2018, the Company issued 12,000 shares of Redeemable Series A-1 Preferred Stock with a par value of $0.0001 per share and a detachable warrant to purchase 534,240 shares of the Company’s common stock. Each preferred share was issued as part of a unit, which consisted of one share of the Redeemable Series A-1 Preferred Stock at $0.01 million per share. On April 13, 2020, the Company amended and restated the certificate of designation of the Company’s Redeemable Series A-1 Preferred Stock. The most significant changes in the amendment included (i) the Redeemable Series A-1 Preferred Stock became pari passu with the Convertible and Redeemable Series A-2 Preferred Stock (Note 17), (ii) the maturity was extended to October 2024; (iii) the Company could use up to $50.0 million of indebtedness or cash on hand to redeem the Redeemable Series A-1 Preferred Stock, and (iv) upon an IPO, up to 50.0% of accumulated dividends could be paid in shares of common stock and (v) the Company could elect to reduce the three year make whole penalty to a two year make whole penalty if the warrant issued in connection with the issuance of the Redeemable Series A-1 Preferred Stock was redeemed in full at a share price of no less than $31.60. Following a partial redemption of outstanding Redeemable Series A-1 Preferred Stock, the dividend rate of the remaining Redeemable Series A-1 Preferred Stock would be reduced proportionally (between 15.0% and 9.0%) in relation to the proportion of Redeemable Series A-1 Preferred Stock redeemed, with the rate increasing by an additional 1.0% for dividends that are accrued versus paid in cash. Based on a qualitative assessment performed by the Company, the Redeemable Series A-1 Preferred Stock amendments did not represent a significant long-term change to the original terms of the instrument and, therefore, there was no change in the accounting of the instrument. On July 27, 2020, the Company redeemed in full the Redeemable Series A-1 Preferred Stock, including the guaranteed minimum two-year dividend. The Redeemable Series A-1 Preferred Stock contained restrictive covenants. Prior to its redemption, the Company was subject to a consolidated total leverage ratio (including the outstanding principal and accrued dividend on the Redeemable Series A-1 Preferred Stock) limit of less than 10.0 times as of the end of any fiscal quarter ending until maturity. Before redemption, the Redeemable Series A-1 Preferred Stock accrued dividends quarterly at an annual rate of 15.0% with respect to dividends that were paid in cash and at an annual rate of 14.2% with respect to dividends that were accrued. At issuance the Company determined that the detachable warrant (Note 12) and the contingent put option were required to be accounted for separately. The contingent put option change in value of $26.3 million and $19.2 million for the three and nine months ended September 30, 2020 was recorded to other expense.
