| Pay vs Performance Disclosure, Table | Pay Versus Performance Table The following table sets forth information concerning the compensation paid to our Chief Executive Officer and to our President and our Chief Operating Officer and Chief Financial Officer (who are our only other NEOs) compared to Company performance for the years ended December 31, 2023 and 2022. We have not presented information for years prior to 2022 because we did not pay our executive officers in any year prior to 2022.

Byrne. References to “Other NEOs” in this section for 2023 refer to Michael Comparato, our President and Jerome S. Baglien, our Chief Operating Officer and Chief Financial Officer, and for 2022 refers to Mr. Baglien. (2) The values reflected in this column reflect the “Total” compensation set forth in the Summary Compensation Table (“SCT”) on page 35. See the footnotes to the SCT for further detail regarding the amounts in this column. (3) Compensation actually paid (“CAP”) is defined by the SEC and is computed in accordance with SEC rules by subtracting the amounts in the “Stock Awards” column of the SCT for each year from the “Total” column of the SCT and then: (i) adding the fair value as of the end of the reported year of all awards granted during the reporting year that are outstanding and unvested as of the end of the reporting year; (ii) adding the amount equal to the change as of the end of the reporting year (from the end of the prior year) in fair value (whether positive or negative) of any awards granted in any prior year that are outstanding and unvested as of the end of the reporting year; (iii) adding, for awards that are granted and vest in the reporting year, the fair value as of the vesting date; (iv) adding the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value (whether positive or negative) of any awards granted in any prior year for which all applicable vesting conditions were satisfied at the end of or during the reporting year; (v) subtracting, for any awards granted in any prior year that are forfeited during the reporting year, the amount equal to the fair value at the end of the prior year; and (vi) adding the value of any dividends (or dividend equivalents) paid in the reporting year on unvested equity awards and the value of accrued dividends (or dividend equivalents) paid on performance awards that vested in the reporting year. The following tables reflect the adjustments made to SCT total compensation to compute CAP for our CEO and average CAP for our other NEOs.

In 2022, the Company compared its TSR to the Bloomberg REIT Mortgage Index, but decided to discontinue doing so as Bloomberg announced that the Bloomberg Mortgage Index should no longer be used for financial benchmarking purposes. The FTSE Mortgage REIT Index is comprised of companies that are similar to us in size with large market capitalizations and is historically comparable to the Bloomberg Mortgage Index. For the period from October 19, 2021, to December 31, 2023, assuming a $100 investment at the closing price on October 19, 2021, and the reinvestment of all dividends, the TSR of the Bloomberg Mortgage Index was $82.07.
