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 Summary Compensation Table for the applicable year.
(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, 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.

For the relevant fiscal year, represents the cumulative total stockholder return of our common stock at the end of such fiscal year. In each case, assume an initial investment of $100 on December 31, 2021.
(6)
The dollar amounts reported represent the amount of net loss reflected in the Company’s audited financial statements for the applicable year. Due to the fact that the Company is not a commercial-stage company, the Company did not have any revenue during the periods presented, other than revenue primarily associated with an upfront payment under the Company’s license and collaboration agreement with GlaxoSmithKline (GSK). Consequently, the Company did not use net income (loss) as a performance measure in its executive compensation program.

Compensation Actually Paid vs. Total Shareholder Return    
Compensation Actually Paid and Cumulative Company TSR
The chart below shows the relationship between the compensation actually paid to our current and former PEO and the average compensation actually paid to our non-PEO NEOs, on the one hand, to the Company’s cumulative TSR over the years presented in the table, on the other.
   
Compensation Actually Paid vs. Net Income    
Compensation Actually Paid and Net Loss
Because the Company is a pre-commercial stage company, we had no revenue during the periods presented, other than revenue primarily associated with an upfront payment under the Company’s license and collaboration agreement with GlaxoSmithKline Intellectual Property (No. 5) Limited and Glaxo Group Limited (together, “GSK”). Consequently, we do not use net income (loss) as a performance measure in our executive compensation program. Moreover, as a pre-commercial stage company with only limited, nonrecurring revenue associated with license and collaboration agreements, we do not believe there is any meaningful relationship between our net income (loss) and compensation actually paid to our NEOs during the periods presented.
   
Total Shareholder Return Amount     $ 8.27 25.06 44.83
