Share-Based Compensation
Share-Based Compensation	8. Share-Based Compensation Performance-Contingent Awards The Company periodically grants performance-contingent share-based awards to employees. For the three months ended March 31, 2022, the Company recognized $0.1 million of share-based compensation expense related to these types of awards. As of March 31, 2022, there were 305,000 shares of performance-contingent restricted share units (“RSUs”) outstanding that have a maximum remaining share-based compensation expense of $2.6 million with performance expiration dates through December 2025. For the three months ended March 31, 2021, the Company recognized $0.5 million of share-based compensation expense related to performance-contingent share-based awards. Share-Based Compensation Modification Due to Corporate Restructuring As a result of the Company’s corporate restructuring announcement in September 2021 (see “Note 10. Corporate Restructuring”), the Board of Directors’ Compensation Committee approved the acceleration of certain equity awards for employees affected by the restructuring. The Company accounted for this acceleration as a Type III modification (improbable to probable) which resulted in a fair value of $1.6 million, as of the modification date, that was recorded in “Restructuring and related expenses” within the condensed consolidated statements of operations. The total cumulative compensation cost previously recognized for these awards of $0.3 million within “Research and development” and “Selling, general and administrative” through the modification date, was reversed. The acceleration resulted in a net incremental share-based compensation expense of $1.3 million for the three months ended March 31, 2022 and impacted approximately 40 terminated employees who met the conditions of the acceleration and departed the Company at the end of February 2022.
