Importantly, the dollar amounts do not reflect the actual average amount of compensation earned by or paid to our Other NEOs as a group during the applicable year.

(9) Total shareholder return as calculated based on a fixed investment of one hundred ($100) dollars measured from the market close on December 31, 2019 (the last trading day of 2019) through and including the end of the fiscal year for each year reported in the table as required by the Rule. (10) Total shareholder return for the Bloomberg REIT Mortgage Index, which we also use for purposes of the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2022. (11) For purposes of the Rule, we have identified Distributable Earnings as our Company-Selected Metric. We define Distributable Earnings as net income (loss) attributable to our stockholders or, without duplication, owners of our subsidiaries, computed in accordance with GAAP, including realized losses not otherwise included in GAAP net income (loss) and excluding (i) non-cash equity compensation expense, (ii) depreciation and amortization, (iii) any unrealized gains or losses or other similar non-cash items that are included in net income for the applicable reporting period, regardless of whether such items are included in other comprehensive income or loss, or in net income, and (iv) one-time events pursuant to changes in GAAP and certain material non-cash income or expense items agreed upon after discussions between our Manager and our Board of Directors and after approval by a majority of our independent directors. The exclusion of depreciation and amortization from the calculation of Distributable Earnings only applies to debt investments related to real estate to the extent we foreclose upon the property or properties underlying such debt investments. Although Distributable Earnings is one important financial performance measure, among others, that the Compensation Committee considers when making compensation decisions with the intent of aligning compensation with Company performance, the Compensation Committee has not historically, and does not currently, evaluate “compensation actually paid” as calculated pursuant to Item 402(v)(2) of Regulation S-K as part of its executive compensation determinations; accordingly, the Compensation Committee does not actually use any financial performance measure specifically to link executive compensation “actually paid” to Company performance. | ||
