Blackstone |Blackstone Mortgage Trust, Inc. DEFINITIONS 15 Distributable Earnings: Blackstone Mortgage Trust, Inc. (“BXMT”) discloses Distributable Earnings in this presentation. Distributable Earnings is a financial measure that is calculated and presented on the basis of methodologies other than in accordance with generally accepted accounting principles in the United States of America (“GAAP”). Distributable Earnings is a non-GAAP measure, which we define as GAAP net income (loss), including realized gains and losses not otherwise included in GAAP net income (loss), and excluding (i) non-cash equity compensation expense, (ii) depreciation and amortization, (iii) unrealized gains (losses), and (iv) certain non-cash items. Distributable Earnings may also be adjusted from time to time to exclude one-time events pursuant to changes in GAAP and certain other non-cash charges as determined by our Manager, subject to approval by a majority of our independent directors. We believe that Distributable Earnings provides meaningful information to consider in addition to our net income and cash flow from operating activities determined in accordance with GAAP. This adjusted measure helps us to evaluate our performance excluding the effects of certain transactions and GAAP adjustments that we believe are not necessarily indicative of our current loan portfolio and operations. We believe Distributable Earnings is a useful financial metric for existing and potential future holders of our class A common stock as historically, over time, Distributable Earnings has been a strong indicator of our dividends per share. Distributable Earnings mirrors the terms of our management agreement between our Manager and us for purposes of calculating our incentive fee expense. Distributable Earnings does not represent net income or cash generated from operating activities and should not be considered as an alternative to GAAP net income, or an indication of our GAAP cash flows from operations, a measure of our liquidity, or an indication of funds available for our cash needs. In addition, our methodology for calculating Distributable Earnings may differ from the methodologies employed by other companies to calculate the same or similar supplemental performance measures, and accordingly, our reported Distributable Earnings may not be comparable to the Distributable Earnings reported by other companies. Non-Consolidated Senior Interests: Senior interests in loans originated and syndicated to third parties. These non-recourse loan participations, which are excluded from the GAAP balance sheet, constitute additional financing capacity and are included in discussions of the loan portfolio.
