From December 2020 through June 2021, we granted 770,500 stock options, subject to shareholder approval of an amendment to the Incentive Plan (“Shareholder Approval”). Under GAAP, if a stock award is subject to shareholder approval, it is not considered granted for accounting purposes until that approval is received. Shareholder Approval was received at our annual meeting of shareholders on July 21, 2021. Accordingly, the accounting grant date of the 770,500 previously-awarded stock options is July 21, 2021, and no expense was recognized for stock options prior to that date.

During the second quarter of 2021, we recognized an $11.5 million reversal of stock-based compensation expense due to the forfeiture of unvested restricted stock and restricted stock units upon the retirement of our former Chief Executive Officer in May 2021.

We expect to recognize the future stock-based compensation expense as follows:
