Equity [Abstract]
Shareholders' Equity	Shareholders’ Equity Pre-2019 Transaction In March 2017, the Company formed the Management Incentive Plan under which certain employees of the Company may be eligible to purchase shares of the Company. In exchange for each share purchase subscription, the purchaser is entitled to a fully vested right to an ordinary share. Additionally, along with a subscription, employees receive a corresponding number of options to acquire additional ordinary shares subject to five years vesting. See Note 17 - Employment and Compensation Arrangements for additional detail related to the options. There were no share subscriptions received prior to or following the close of the 2019 Transaction for the three months ended March 31, 2021. Post-2019 Transaction Immediately prior to the closing of the 2019 Transaction, there were 87,749,999 shares of Churchill ordinary stock issued and outstanding, consisting of (i) 68,999,999 public shares (Class A) and (ii) 18,750,000 founder shares (Class B). On May 13, 2019, in connection with the 2019 Transaction, all of the Class B ordinary stock converted into Class A ordinary stock of the post-combination company on a one-for-one basis, and effected the reclassification and conversion of all of the Class A ordinary stock and Class B ordinary stock into a single class of ordinary stock of Clarivate Plc. One stockholder elected to have one share redeemed in connection with the 2019 Transaction. In June 2019, the Company formed the 2019 Incentive Award Plan under which employees of the Company may be eligible to purchase shares of the Company. See Note 17 - Employment and Compensation Arrangements for additional detail related to the 2019 Incentive Award Plan. In exchange for each share subscription purchased, the purchaser is entitled to a fully vested right to an ordinary share. At March 31, 2021 there were unlimited shares of ordinary stock authorized, and 611,355,226 shares issued and outstanding, with a par value of $0.00. The Company held 6,325,860 shares as treasury shares as of March 31, 2021 and December 31, 2020. The Company’s ordinary stockholders are entitled to one vote per share. Warrants Upon consummation of the 2019 Transaction, the Company had warrants outstanding to purchase an aggregate of 52,800,000 ordinary shares. Each outstanding whole warrant of Churchill represents the right to purchase one ordinary share of the Company in lieu of one share of Churchill ordinary stock upon closing of the 2019 Transaction at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing upon the later of (i) 30 days after the completion of the 2019 Transaction and (ii) September 11, 2019. The holder does not have the right to exercise the Warrants to the extent that they would beneficially own in excess of 4.9% or 9.8% (as specified by the holder) of the shares of ordinary stock outstanding immediately after giving effect to such exercise. As of December 31, 2019, 100,114 warrants had been exercised. During the period January 1, 2020 through February 21, 2020, 24,132,666 of the Company’s outstanding public warrants were exercised for one ordinary share per whole public warrant at a price of $11.50 per share. On February 20, 2020, we announced the redemption of all of our outstanding public warrants to purchase our ordinary shares that were issued as part of the units sold in the Churchill Capital Corp initial public offering that remained outstanding at 5:00 p.m. New York City time on March 23, 2020, for a redemption price of $0.01 per public warrant. In addition, our board of directors elected that, upon delivery of the notice of the redemption on February 20, 2020, all public warrants were to be exercised only on a “cashless basis.” Accordingly, by virtue of the cashless exercise of public warrants, exercising public warrant holders received 0.4626 of an ordinary share for each public warrant, and 4,747,432 ordinary shares were issued for public warrants exercised on a cashless basis and 4,649 public warrants were redeemed for $0.01 per public warrant. As of December 31, 2020, no public warrants were outstanding. Merger Shares Upon consummation of the 2019 Transaction, there were 7,000,000 ordinary shares of Clarivate that are issuable to persons designated by Messrs. Stead and Klein, including themselves, if the last sale price of Clarivate’s ordinary shares is at least $20.00 for 40 days over a 60 consecutive trading day period on or before the sixth anniversary of the closing of the 2019 Transaction. On January 31, 2020, our Board agreed to waive all performance vesting conditions associated with the Merger Shares (as defined below). The Merger Shares were issued as ordinary shares to persons designated by Jerre Stead and Michael Klein on June 1, 2020 as part of the June 2020 underwritten public offering.
