Performance-Contingent Awards

In 2016, the Compensation Committee of the Company’s board of directors (“Compensation Committee”) approved the grant of 1,575,000 performance-contingent restricted share awards (“RSAs”) and 135,000 performance-contingent restricted share units (“RSUs”) to senior management. The vesting of such awards is dependent on the Company meeting its

critical operating goals and objectives during the five-year period from 2016 to December 31, 2020, as well as, continued employment. The goals that must be met in order for the performance-contingent RSAs and RSUs to vest are strategically important for the Company, and the Compensation Committee believes the goals should increase shareholder value. The awards have dual triggers of vesting based upon the achievement of these goals and continued employment.

Expense associated with these awards may be recognized during the years 2016 to 2020 depending on the probability of meeting certain performance conditions. Compensation expense relating to awards subject to performance conditions is recognized if it is considered probable that the performance goals will be achieved. The probability of achievement is reassessed at each quarter-end reporting period. Previously recognized expense is reversed in the period in which it becomes probable that the requisite service period will not be rendered. The awards are broken into three separate tranches.

As of June 30, 2020, there were 414,000 of these performance-contingent RSAs and 54,000 of these performance-contingent RSUs outstanding, and as of June 30, 2019, there were 877,500 of these performance-contingent RSAs and 101,250 of these performance-contingent RSUs outstanding. The performance conditions associated with the first tranche of these awards were completed in the second quarter of 2018, and the expense associated with the first tranche was fully recognized in 2018.

The performance conditions associated with the second tranche of these awards were completed in the first quarter of 2019, and as of March 31, 2020, the expense associated with this second tranche was fully recognized. For the six months ended June 30, 2020, the Company recognized $0.4 million of share-based compensation expense related to the second tranche of these awards. For three and six months ended June 30, 2019, the Company recognized ($0.3) million and $0.5 million, respectively, of share-based compensation expense related to the second tranche of these awards.

In the first quarter of 2020, the performance conditions associated with the remaining third tranche were completed and, as a result, the Company recognized $0.6 million and $1.3 million of share-based compensation expense related to these awards for the three and six months ended June 30, 2020, respectively. As of June 30, 2020, the maximum remaining expense associated with the third tranche is $1.7 million (allocated as $0.6 million for research and development expense and $1.1 million for selling, general and administrative expense) and will be amortized through the first quarter of 2021.

Separate from the performance-contingent awards described above, the Company periodically grants performance-contingent RSUs to individual employees. For the three and six months ended June 30, 2020, the Company recognized $0.5 million and $0.7 million, respectively, of share-based compensation expense related to such awards. As of June 30, 2020, there were 120,000 shares of these performance-contingent RSUs outstanding that have a maximum remaining share-based compensation expense of $1.8 million with performance expiration dates ranging from December 2020 to June 2022.
