[1] The number of shares of common stock issuable upon the vesting of the remaining outstanding PUs as of December 31, 2023 was reduced by 14,365 shares as a result of a book value impairment event that occurred pursuant to the terms of the long term equity incentive compensation plans (the “Plans”) established under the Company’s Incentive Plans. The book value impairment event occurred when the Company's book value per share declined by more than 15% during the quarter ended September 30, 2023 and the Company’s book value per share decline from July 1, 2023 to December 31, 2023 was more than 10%. The Plans provide that if such a book value impairment event occurs, then the number of outstanding PUs that are outstanding as of the last day of such two quarter period shall be reduced by 15%.
