Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	ORGANIZATION References herein to “Blackstone Mortgage Trust,” “Company,” “we,” “us” or “our” refer to Blackstone Mortgage Trust, Inc., a Maryland corporation, and its subsidiaries unless the context specifically requires otherwise. Blackstone Mortgage Trust is a real estate finance company that originates senior loans collateralized by commercial real estate in North America, Europe, and Australia. Our portfolio is composed primarily of loans secured by high-quality, institutional assets in major markets, sponsored by experienced, well-capitalized real estate investment owners and operators. These senior loans are capitalized by accessing a variety of financing options, including borrowing under our credit facilities, issuing CLOs or single-asset securitizations, and corporate financing, depending on our view of the most prudent financing option available for each of our investments. We are not in the business of buying or trading securities, and the only securities we own are the retained interests from our securitization financing transactions, which we have not financed. We are externally managed by BXMT Advisors L.L.C., or our Manager, a subsidiary of Blackstone Inc., or Blackstone, and are a real estate investment trust, or REIT, traded on the New York Stock Exchange, or NYSE, under the symbol “BXMT.” Our principal executive offices are located at 345 Park Avenue, 24th Floor, New York, New York 10154. We conduct our operations as a REIT for U.S. federal income tax purposes. We generally will not be subject to U.S. federal income taxes on our taxable income to the extent that we annually distribute all of our net taxable income to stockholders and maintain our qualification as a REIT. We also operate our business in a manner that permits us to maintain an exclusion from registration under the Investment Company Act of 1940, as amended. We are organized as a holding company and conduct our business primarily through our various subsidiaries.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, and include, on a consolidated basis, our accounts, the accounts of our wholly-owned subsidiaries, majority-owned subsidiaries, and variable interest entities, or VIEs, of which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications have been made in the presentation of the prior period statements of changes in equity related to restricted class A common stock and in the loans receivable disclosures related to risk ratings, property type, and geography in Note 3 to conform to the current period presentation. Principles of Consolidation We consolidate all entities that we control through either majority ownership or voting rights. In addition, we consolidate all VIEs of which we are considered the primary beneficiary. VIEs are defined as entities in which equity investors (i) do not have an interest with the characteristics of a controlling financial interest and/or (ii) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The entity that consolidates a VIE is known as its primary beneficiary and is generally the entity with (i) the power to direct the activities that most significantly affect the VIE’s economic performance and (ii) the right to receive benefits from the VIE or the obligation to absorb losses of the VIE that could be significant to the VIE. In 2017, we entered into a joint venture, or our Multifamily Joint Venture, with Walker & Dunlop Inc. to originate, hold, and finance multifamily bridge loans. Pursuant to the terms of the agreements governing the joint venture, Walker & Dunlop contributed 15% of the venture’s equity capital and we contributed 85%. We consolidate the Multifamily Joint Venture as we have a controlling financial interest. The non-controlling interests included on our consolidated balance sheets represent the equity interests in our Multifamily Joint Venture that are owned by Walker & Dunlop. A portion of our Multifamily Joint Venture’s consolidated equity and results of operations are allocated to these non-controlling interests based on Walker & Dunlop’s pro rata ownership of our Multifamily Joint Venture. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may ultimately differ materially from those estimates. Revenue Recognition Interest income from our loans receivable portfolio is recognized over the life of each investment using the effective interest method and is recorded on the accrual basis. Recognition of fees, premiums, and discounts associated with these investments is deferred and recorded over the term of the loan as an adjustment to yield. Income accrual is generally suspended for loans at the earlier of the date at which payments become 90 days past due or when, in our opinion, recovery of income and principal becomes doubtful. Interest received is then recorded as income or as a reduction in the amortized cost basis, based on the specific facts and circumstances, until accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. In addition, for loans we originate, the related origination expenses are deferred and recognized as a reduction to interest income, however expenses related to loans we acquire are included in general and administrative expenses as incurred. Cash and Cash Equivalents Cash and cash equivalents represent cash held in banks and liquid investments with original maturities of three months or less. We may have bank balances in excess of federally insured amounts; however, we deposit our cash and cash equivalents with high credit-quality institutions to minimize credit risk exposure. We have not experienced, and do not expect, any losses on our cash or cash equivalents. As of both December 31, 2023 and 2022, we had no restricted cash on our consolidated balance sheets. Through our subsidiaries, we have oversight of certain servicing accounts held with third-party servicers, or Servicing Accounts, which relate to borrower escrows and other cash balances aggregating $640.6 million and $459.6 million as of December 31, 2023 and 2022, respectively. This cash is maintained in segregated bank accounts, and these amounts are not included in the assets and liabilities presented in our consolidated balance sheets. Cash in these Servicing Accounts will be transferred by the respective third-party servicer to the borrower or us under the terms of the applicable loan agreement upon occurrence of certain future events. We do not generate any revenue or incur any expenses as a result of these Servicing Accounts. Loans Receivable We originate and purchase commercial real estate debt and related instruments generally to be held as long-term investments at amortized cost. Current Expected Credit Losses Reserve The current expected credit loss, or CECL, reserve required under the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 326 “Financial Instruments – Credit Losses,” or ASC 326, reflects our current estimate of potential credit losses related to our loans included in our consolidated balance sheets. Changes to the CECL reserves are recognized through net income on our consolidated statements of operations. While ASC 326 does not require any particular method for determining the CECL reserves, it does specify the reserves should be based on relevant information about past events, including historical loss experience, current portfolio and market conditions, and reasonable and supportable forecasts for the duration of each respective loan. In addition, other than a few narrow exceptions, ASC 326 requires that all financial instruments subject to the CECL model have some amount of loss reserve to reflect the GAAP principal underlying the CECL model that all loans and similar assets have some inherent risk of loss, regardless of credit quality, subordinate capital, or other mitigating factors. We estimate our CECL reserves primarily using the Weighted-Average Remaining Maturity, or WARM method, which has been identified as an acceptable loss-rate method for estimating CECL reserves in FASB Staff Q&A Topic 326, No. 1. The WARM method requires us to reference historic loan loss data across a comparable data set and apply such loss rate to each of our loans over their expected remaining term, taking into consideration expected economic conditions over the relevant timeframe. We apply the WARM method for the majority of our loan portfolio, which consists of loans that share similar risk characteristics. In certain instances, for loans with unique risk characteristics, we may instead use a probability-weighted model that considers the likelihood of default and expected loss given default for each such individual loan. Application of the WARM method to estimate CECL reserves requires judgment, including (i) the appropriate historical loan loss reference data, (ii) the expected timing and amount of future loan fundings and repayments, and (iii) the current credit quality of our portfolio and our expectations of performance and market conditions over the relevant time period. To estimate the historic loan losses relevant to our portfolio, we have augmented our historical loan performance, with market loan loss data licensed from Trepp LLC. This database includes commercial mortgage-backed securities, or CMBS, issued since January 1, 1999 through November 30, 2023. Within this database, we focused our historical loss reference calculations on the most relevant subset of available CMBS data, which we determined based on loan metrics that are most comparable to our loan portfolio including asset type, geography, and origination loan-to-value, or LTV. We believe this CMBS data, which includes month-over-month loan and property performance, is the most relevant, available, and comparable dataset to our portfolio. Our loans typically include commitments to fund incremental proceeds to our borrowers over the life of the loan. These future funding commitments are also subject to the CECL model. The CECL reserve related to future loan fundings is recorded as a component of other liabilities on our consolidated balance sheets. This CECL reserve is estimated using the same process outlined above for our outstanding loan balances, and changes in this component of the CECL reserve will similarly impact our consolidated net income. For both the funded and unfunded portions of our loans, we consider our internal risk rating of each loan as the primary credit quality indicator underlying our assessment. The CECL reserves are measured on a collective basis wherever similar risk characteristics exist within a pool of similar assets. We have identified the following pools and measure the reserve for credit losses using the following methods: • U.S. Loans : WARM method that incorporates a subset of historical loss data, expected weighted-average remaining maturity of our loan pool, and an economic view. • Non-U.S. Loans : WARM method that incorporates a subset of historical loss data, expected weighted-average remaining maturity of our loan pool, and an economic view. • Unique Loans : a probability of default and loss given default model, assessed on an individual basis. • Impaired Loans : impairment is indicated when it is deemed probable that we will not be able to collect all amounts due to us pursuant to the contractual terms of the loan. Determining that a loan is impaired requires significant judgment from management and is based on several factors including (i) the underlying collateral performance, (ii) discussions with the borrower, (iii) borrower events of default, and (iv) other facts that impact the borrower’s ability to pay the contractual amounts due under the terms of the loan. If a loan is determined to be impaired, we record the impairment as a component of our CECL reserves by applying the practical expedient for collateral dependent loans. The CECL reserves are assessed on an individual basis for these loans by comparing the estimated fair value of the underlying collateral, less costs to sell, to the book value of the respective loan. These valuations require significant judgments, which include assumptions regarding capitalization rates, discount rates, leasing, creditworthiness of major tenants, occupancy rates, availability and cost of financing, exit plan, loan sponsorship, actions of other lenders, and other factors deemed relevant by us. Actual losses, if any, could ultimately differ materially from these estimates. We only expect to charge-off the impairment losses in our consolidated financial statements prepared in accordance with GAAP if and when such amounts are deemed non-recoverable. This is generally at the time a loan is repaid or foreclosed. However, non-recoverability may also be concluded if, in our determination, it is nearly certain that all amounts due will not be collected. Contractual Term and Unfunded Loan Commitments Expected credit losses are estimated over the contractual term of each loan, adjusted for expected repayments. As part of our quarterly review of our loan portfolio, we assess the expected repayment date of each loan, which is used to determine the contractual term for purposes of computing our CECL reserves. Additionally, the expected credit losses over the contractual period of our loans are subject to the obligation to extend credit through our unfunded loan commitments. The CECL reserve for unfunded loan commitments is adjusted quarterly, as we consider the expected timing of future funding obligations over the estimated life of the loan. The considerations in estimating our CECL reserve for unfunded loan commitments are similar to those used for the related outstanding loans receivable. Credit Quality Indicator Our risk rating is our primary credit quality indicator in assessing our current expected credit loss reserve. We perform a quarterly risk review of our portfolio of loans, and assign each loan a risk rating based on a variety of factors, including, without limitation, origination LTV, debt yield, property type, geographic and local market dynamics, physical condition, cash flow volatility, leasing and tenant profile, loan structure and exit plan, and project sponsorship. Based on a 5-point scale, our loans are rated “l” through “5,” from less risk to greater risk, relative to our loan portfolio in the aggregate, which ratings are defined as follows: 1 - Very Low Risk 2 - Low Risk 3 - Medium Risk 4 - High Risk/Potential for Loss: A loan that has a risk of realizing a principal loss. 5 - Impaired/Loss Likely: A loan that has a very high risk of realizing a principal loss or has otherwise incurred a principal loss. Estimation of Economic Conditions In addition to the WARM method computations and probability-weighted models described above, our CECL reserves are also adjusted to reflect our estimation of the current and future economic conditions that impact the performance of the commercial real estate assets securing our loans. These estimations include unemployment rates, interest rates, expectations of inflation and/or recession, and other macroeconomic factors impacting the likelihood and magnitude of potential credit losses for our loans during their anticipated term. In addition to the CMBS data we have licensed from Trepp LLC, we have also licensed certain macroeconomic financial forecasts to inform our view of the potential future impact that broader economic conditions may have on our loan portfolio’s performance. We generally also incorporate information from other sources, including information and opinions available to our Manager, to further inform these estimations. This process requires significant judgments about future events that, while based on the information available to us as of the balance sheet date, are ultimately indeterminate and the actual economic condition impacting our portfolio could vary significantly from the estimates we made as of December 31, 2023. Derivative Financial Instruments We classify all derivative financial instruments as either other assets or other liabilities on our consolidated balance sheets at fair value. On the date we enter into a derivative contract, we designate each contract as (i) a hedge of a net investment in a foreign operation, or net investment hedge, (ii) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability, or cash flow hedge, (iii) a hedge of a recognized asset or liability, or fair value hedge, or (iv) a derivative instrument not to be designated as a hedging derivative, or non-designated hedge. For all derivatives other than those designated as non-designated hedges, we formally document our hedge relationships and designation at the contract’s inception. This documentation includes the identification of the hedging instruments and the hedged items, its risk management objectives, strategy for undertaking the hedge transaction and our evaluation of the effectiveness of its hedged transaction. On a quarterly basis, we also formally assess whether the derivative we designated in each hedging relationship is expected to be, and has been, highly effective in offsetting changes in the value or cash flows of the hedged items. If it is determined that a derivative is not highly effective at hedging the designated exposure, hedge accounting is discontinued and the changes in fair value of the instrument are included in net income prospectively. Our net investment hedges are assessed using a method based on changes in spot exchange rates. Gains and losses, representing hedge components excluded from the assessment of effectiveness, are recognized in interest income on our consolidated statements of operations over the contractual term of our net investment hedges on a systematic and rational basis, as documented at hedge inception in accordance with our accounting policy election. All other changes in the fair value of our derivative instruments that qualify as hedges are reported as a component of accumulated other comprehensive income (loss) on our consolidated financial statements. Deferred gains and losses are reclassified out of accumulated other comprehensive income (loss) and into net income in the same period or periods during which the hedged transaction affects earnings, and are presented in the same line item as the earnings effect of the hedged item. For cash flow hedges, this is typically when the periodic swap settlements are made, while for net investment hedges, this occurs when the hedged item is sold or substantially liquidated. To the extent a derivative does not qualify for hedge accounting and is deemed a non-designated hedge, the changes in its fair value are included in net income concurrently. Proceeds or payments from periodic settlements of derivative instruments are classified on our consolidated statement of cash flows in the same section as the underlying hedged item. Secured Debt and Asset-Specific Debt We record investments financed with secured debt or asset-specific debt as separate assets and the related borrowings under any secured debt or asset-specific debt are recorded as separate liabilities on our consolidated balance sheets. Interest income earned on the investments and interest expense incurred on the secured debt or asset-specific debt are reported separately on our consolidated statements of operations. Loan Participations Sold In certain instances, we have executed a syndication of a non-recourse loan interest to a third-party. Depending on the particular structure of the syndication, the loan interest may remain on our GAAP balance sheet or, in other cases, the sale will be recognized and the loan interest will no longer be included in our consolidated financial statements. When these sales are not recognized under GAAP we reflect the transaction by recording a loan participation sold liability on our consolidated balance sheet, however this gross presentation does not impact stockholders’ equity or net income. When the sales are recognized, our balance sheet only includes our remaining loan interest, and excludes the interest in the loan that we sold. Term Loans We record our term loans as liabilities on our consolidated balance sheets. Where applicable, any issue discount or transaction expenses are deferred and amortized through the maturity date of the term loans as additional non-cash interest expense. Senior Secured Notes We record our senior secured notes as liabilities on our consolidated balance sheets. Where applicable, any issue discount or transaction expenses are deferred and amortized through the maturity date of the senior secured notes as additional non-cash interest expense. Convertible Notes Convertible note proceeds, unless issued with a substantial premium or an embedded conversion feature, are classified as debt. Additionally, shares issuable under our convertible notes are included in diluted earnings per share in our consolidated financial statements, if the effect is dilutive, using the if-converted method, regardless of settlement intent. Where applicable, any issue discount or transaction expenses are deferred and amortized through the maturity date of the convertible notes as additional non-cash interest expense. Deferred Financing Costs The deferred financing costs that are included as a reduction in the net book value of the related liability on our consolidated balance sheets include issuance and other costs related to our debt obligations. These costs are amortized as interest expense using the effective interest method over the life of the related obligations. Underwriting Commissions and Offering Costs Underwriting commissions and offering costs incurred in connection with common stock offerings are reflected as a reduction of additional paid-in capital. Costs incurred that are not directly associated with the completion of a common stock offering are expensed when incurred. Fair Value of Financial Instruments The “Fair Value Measurements and Disclosures” Topic o f the FASB, or ASC 820, defines fair value, establishes a framework for measuring fair value, and requires certain disclosures about fair value measurements under GAAP. Specifically, this guidance defines fair value based on exit price, or the price that would be received upon the sale of an asset or the transfer of a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a fair value hierarchy that prioritizes and ranks the level of market price observability used in measuring financial instruments. Market price observability is affected by a number of factors, including the type of financial instrument, the characteristics specific to the financial instrument, and the state of the marketplace, including the existence and transparency of transactions between market participants. Financial instruments with readily available quoted prices in active markets generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. Financial instruments measured and reported at fair value are classified and disclosed based on the observability of inputs used in the determination, as follows: • Level 1: Generally includes only unadjusted quoted prices that are available in active markets for identical financial instruments as of the reporting date. • Level 2: Pricing inputs include quoted prices in active markets for similar instruments, quoted prices in less active or inactive markets for identical or similar instruments where multiple price quotes can be obtained, and other observable inputs, such as interest rates, yield curves, credit risks, and default rates. • Level 3: Pricing inputs are unobservable for the financial instruments and include situations where there is little, if any, market activity for the financial instrument. These inputs require significant judgment or estimation by management of third-parties when determining fair value and generally represent anything that does not meet the criteria of Levels 1 and 2. Certain of our other assets are reported at fair value, as of quarter-end, either (i) on a recurring basis or (ii) on a nonrecurring basis, as a result of impairment or other events. Our assets that are recorded at fair value are discussed further in Note 17. We generally value our assets recorded at fair value by either (i) discounting expected cash flows based on assumptions regarding the collection of principal and interest and estimated market rates, or (ii) obtaining assessments from third-parties. For collateral-dependent loans that are identified as impaired, we measure impairment by comparing our estimation of the fair value of the underlying collateral, less costs to sell, to the book value of the respective loan. These valuations require significant judgments, which include assumptions regarding capitalization rates, discount rates, leasing, creditworthiness of major tenants, occupancy rates, availability and cost of financing, exit plan, loan sponsorship, actions of other lenders, and other factors. As of December 31, 2023, we had an aggregate $417.7 million asset-specific CECL reserve related to 13 of our loans receivable with an aggregate amortized cost basis of $1.9 billion, net of cost-recovery proceeds. The CECL reserve was recorded based on our estimation of the fair value of the loans' aggregate underlying collateral as of December 31, 2023. These loans receivable are therefore measured at fair value on a nonrecurring basis using significant unobservable inputs, and are classified as Level 3 assets in the fair value hierarchy. We estimated the fair value of these loans receivable by considering a variety of inputs including property performance, market data, and comparable sales, as applicable. The significant unobservable inputs used include the exit capitalization rate assumption used to forecast the future sale price of the underlying real estate collateral, which ranged from 5.25% to 8.00%, and the unlevered discount rate, which ranged from 7.28% to 11.00%. We are also required by GAAP to disclose fair value information about financial instruments, which are not otherwise reported at fair value in our consolidated balance sheet, to the extent it is practicable to estimate a fair value for those instruments. These disclosure requirements exclude certain financial instruments and all non-financial instruments. The following methods and assumptions are used to estimate the fair value of each class of financial instruments, for which it is practicable to estimate that value: • Cash and cash equivalents: The carrying amount of cash and cash equivalents approximates fair value. • Loans receivable, net: The fair values of these loans were estimated using a discounted cash flow methodology, taking into consideration various factors including capitalization rates, discount rates, leasing, credit worthiness of major tenants, occupancy rates, availability and cost of financing, exit plan, loan sponsorship, actions of other lenders, and other factors. • Derivative financial instruments: The fair value of our foreign currency and interest rate contracts was estimated using advice from a third-party derivative specialist, based on contractual cash flows and observable inputs comprising foreign currency rates and credit spreads. • Secured debt, net: The fair value of these instruments was estimated based on the rate at which a similar credit facility would currently be priced. • Securitized debt obligations, net: The fair value of these instruments was estimated by utilizing third-party pricing service providers. In determining the value of a particular investment, pricing service providers may use broker-dealer quotations, reported trades, or valuation estimates from their internal pricing models to determine the reported price. • Asset-specific debt, net: The fair value of these instruments was estimated based on the rate at which a similar agreement would currently be priced. • Loan participations sold, net: The fair value of these instruments was estimated based on the value of the related loan receivable asset. • Term loans, net: The fair value of these instruments was estimated by utilizing third-party pricing service providers. In determining the value of a particular investment, pricing service providers may use broker-dealer quotations, reported trades, or valuation estimates from their internal pricing models to determine the reported price. • Senior secured notes, net: The fair value of these instruments was estimated by utilizing third-party pricing service providers. In determining the value of a particular investment, pricing service providers may use broker-dealer quotations, reported trades, or valuation estimates from their internal pricing models to determine the reported price. • Convertible notes, net: Each series of the convertible notes is actively traded and their fair values were obtained using quoted market prices. Income Taxes Our financial results generally do not reflect provisions for current or deferred income taxes on our REIT taxable income. We believe that we operate in a manner that will continue to allow us to be taxed as a REIT and, as a result, we generally do not expect to pay substantial corporate level taxes other than those payable by our taxable REIT subsidiaries. If we were to fail to meet these requirements, we may be subject to federal, state, and local income tax on current and past income, and penalties. Refer to Note 15 for additional information. Stock-Based Compensation Our stock-based compensation consists of awards issued to our Manager, certain individuals employed by an affiliate of our Manager, and certain members of our board of directors that vest over the life of the awards, as well as deferred stock units issued to certain members of our board of directors. Stock-based compensation expense is recognized for these awards in net income on a variable basis over the applicable vesting period of the awards, based on the value of our class A common stock. Refer to Note 16 for additional information. Earnings per Share Basic earnings per share, or Basic EPS, is computed in accordance with the two-class method and is based on (i) the net earnings allocable to our class A common stock, including restricted class A common stock and deferred stock units, divided by (ii) the weighted-average number of shares of our class A common stock, including restricted class A common stock and deferred stock units outstanding during the period. Our restricted class A common stock is considered a participating security, as defined by GAAP, and has been included in our Basic EPS under the two-class method as these restricted shares have the same rights as our other shares of class A common stock, including participating in any gains or losses. Diluted earnings per share, or Diluted EPS, is determined using the if-converted method, and is based on (i) the net earnings, adjusted for interest expense incurred on our convertible notes during the relevant period, net of incentive fees, allocable to our class A common stock, including restricted class A common stock and deferred stock units, divided by (ii) the weighted-average number of shares of our class A common stock, including restricted class A common stock, deferred stock units, and shares of class A common stock issuable under our convertible notes. Refer to Note 13 for additional discussion of earnings per share. Foreign Currency In the normal course of business, we enter into transactions not denominated in United States, or U.S., dollars. Foreign exchange gains and losses arising on such transactions are recorded as a gain or loss in our consolidated statements of operations. In addition, we consolidate entities that have a non-U.S. dollar functional currency. Non-U.S. dollar denominated assets and liabilities are translated to U.S. dollars at the exchange rate prevailing at the reporting date and income, expenses, gains, and losses are translated at the average exchange rate over the applicable period. Cumulative translation adjustments arising from the translation of non-U.S. dollar denominated subsidiaries are recorded in other comprehensive income (loss). Recent Accounting Pronouncements In December 2023, the FASB issued Accounting Standards Update, or ASU, 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” or ASU 2023-09. ASU 2023-09 requires additional disaggregated disclosures on the entity’s effective tax rate reconciliation and additional details on income taxes paid. ASU 2023-09 is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2024 and early adoption is permitted. We do not expect the adoption of ASU 2023-09 to have a material impact on our consolidated financial statements. In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” or ASU 2023-07. ASU 2023-07 enhances the disclosures required for reportable segments on an annual and interim basis. ASU 2023-07 is effective on a retrospective basis for annual periods beginning after December 15, 2023, for interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. We do not expect the adoption of ASU 2023-07 to have a material impact on our consolidated financial statements. In March 2022, the FASB issued ASU, 2022-02 “Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures,” or ASU 2022-02. ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings and requires disclosure of current-period gross write-offs by year of loan origination. Additionally, ASU 2022-02 updates the accounting for credit losses under ASC 326 and adds enhanced disclosures wi

Loans Receivable, Net	LOANS RECEIVABLE, NET The following table details overall statistics for our loans receivable portfolio ($ in thousands): December 31, 2023 December 31, 2022 Number of loans 178 203 Principal balance $ 23,923,719 $ 25,160,343 Net book value $ 23,210,076 $ 24,691,743 Unfunded loan commitments (1) $ 2,430,664 $ 3,806,153 Weighted-average cash coupon (2) + 3.37 % + 3.44 % Weighted-average all-in yield (2) + 3.71 % + 3.84 % Weighted-average maximum maturity (years) (3) 2.4 3.1 (1) Unfunded commitments will primarily be funded to finance our borrowers’ construction or development of real estate-related assets, capital improvements of existing assets, or lease-related expenditures. These commitments will generally be funded over the term of each loan, subject in certain cases to an expiration date. (2) The weighted-average cash coupon and all-in yield are expressed as a spread over the relevant floating benchmark rates, which include SOFR, USD LIBOR, SONIA, EURIBOR, and other indices, as applicable to each loan. As of December 31, 2023 99% of our loans by principal balance earned a floating rate of interest, primarily indexed to SOFR, and the remaining 1% of our loans earned a fixed rate of interest. As of December 31, 2022, substantially all of our loans by principal balance earned a floating rate of interest, primarily indexed to SOFR and USD LIBOR. Floating rate exposure as of December 31, 2023 includes an interest rate swap we entered into with a notional amount of $229.9 million that effectively converts certain of our fixed rate loan exposure to floating rate exposure. In addition to cash coupon, all-in yield includes the amortization of deferred origination and extension fees, loan origination costs, and purchase discounts, as well as the accrual of exit fees. Excludes loans accounted for under the cost-recovery method. (3) Maximum maturity assumes all extension options are exercised by the borrower, however our loans may be repaid prior to such date. As of December 31, 2023, 14% of our loans by principal balance were subject to yield maintenance or other prepayment restrictions and 86% were open to repayment by the borrower without penalty. As of December 31, 2022, 50% of our loans by principal balance were subject to yield maintenance or other prepayment restrictions and 50% were open to repayment by the borrower without penalty.

(3) As of December 31, 2023, the weighted-average index rate floor of our loans receivable principal balance was 0.56%. Excluding 0.0% index rate floors and loans with no floor, the weighted-average index rate floor was 1.00%. As of December 31, 2022, the weighted-average index rate floor of our loans receivable principal balance was 0.36%.

Loan Risk Ratings As further described in Note 2, we evaluate our loan portfolio on a quarterly basis. In conjunction with our quarterly loan portfolio review, we assess the risk factors of each loan, and assign a risk rating based on several factors. Factors considered in the assessment include, but are not limited to, risk of loss, origination LTV, debt yield, collateral performance, structure, exit plan, and sponsorship. Loans are rated “1” (less risk) through “5” (greater risk), which ratings are defined in Note 2.

During the year ended December 31, 2023, we recorded an aggregate increase of $250.8 million in the CECL reserves against our loans receivable portfolio, bringing our total loans receivable CECL reserve to $576.9 million as of December 31, 2023. These CECL reserves reflect certain impaired loans in our portfolio, as well as an additional increase in our CECL reserves due to macroeconomic conditions. During the three months ended December 31, 2023, we recorded an aggregate net increase of $95.1 million in the asset-specific CECL reserve related to our impaired loans. The increase was primarily driven by three additional loans that were impaired during the three months ended December 31, 2023. As of December 31, 2023, the income accrual was suspended on these loans as recovery of income and principal was doubtful. During the three months ended December 31, 2023, we recorded $5.9 million of interest income on these three loans. As of December 31, 2023, we had an aggregate $417.7 million asset-specific CECL reserve related to 13 of our loans receivable, with an aggregate amortized cost basis of $1.9 billion, net of cost-recovery proceeds. This CECL reserve was recorded based on our estimation of the fair value of each of the loan's underlying collateral as of December 31, 2023. No income was recorded on our impaired loans subsequent to determining that they were impaired. As of December 31, 2023, one of these loans with an amortized cost basis of $140.0 million, was past its current maturity date. This loan was less than 30 days past due on its interest payment and had a risk rating of “5”. As of December 31, 2023, all other borrowers were compliant with the contractual terms of each respective loan, including any required payment of interest. During the year ended December 31, 2023, we received an aggregate $53.0 million of cash proceeds from such loans that were applied as a reduction to the amortized cost basis of each respective loan. Refer to Note 2 for further discussion of our policies on revenue recognition and our CECL reserves. As of December 31, 2022, we had a $189.8 million CECL reserve specifically related to five of our loans receivable, with an amortized cost basis of $929.1 million. This CECL reserve was recorded based on our estimation of the fair value of each of the loan’s underlying collateral as of December 31, 2022. Our primary credit quality indicator is our risk ratings, which are further discussed above.

Loan Modifications Pursuant to ASC 326 During the year ended December 31, 2023, we entered into five loan modifications that require disclosure pursuant to ASC 326. Four of these loans were collateralized by office assets and one was collateralized by a hospitality asset. Three of the loan modifications included other-than-insignificant payment delays, specifically the option to pay interest in-kind. For one of the loans the maximum maturity date was extended by one year, the borrower contributed $2.0 million of additional reserves, and the interest rate increased by 5.11%. The second modification included an additional 4.00% exit fee. The third modification included an additional 2.00% exit fee and the interest rate increased by 2.00%. As of December 31, 2023, the aggregate amortized cost basis of these loans was $546.3 million, or 2.3% of our aggregate loans receivable portfolio, with an aggregate $10.0 million of unfunded commitments. The loans were performing pursuant to their contractual terms as of December 31, 2023, had risk ratings of “5” as of December 31, 2023, and have asset-specific CECL reserves. The other two loan modifications included a combination of changes to the contractual terms of the loans, including term extensions, other-than-insignificant payment delays, and/or interest rate reductions. The first loan modification included a term extension of 19 months, a rate reduction of 2.74% and conversion to fixed rate, with a portion of the interest paid in-kind. The borrower repaid $4.9 million of the loan at the time of modification, with an additional $2.5 million of repayment due during the initial maturity period. The second loan modification included a term extension of 4.5 years, a rate increase of 8.50% with interest paid in-kind, a borrower contribution of $2.0 million of additional reserves, and a $50.0 million increase in our total loan commitment. As of December 31, 2023, the aggregate amortized cost basis of these loans was $434.5 million, or 1.8% of our aggregate loans receivable portfolio, with an aggregate $40.0 million of unfunded commitments. The loans were performing pursuant to their contractual terms as of December 31, 2023. As of December 31, 2023, one of these loans had a risk rating of “4”, and its modified terms were included in the determination of our general CECL reserve, and the other loan had a risk rating of “5” and has an asset-specific CECL reserve. Loan modifications that allow the option to pay interest in-kind increase our potential economics and the size of our secured claim, as interest is capitalized and added to the outstanding principal balance for applicable loans. As of December 31, 2023, all of our loans with a risk rating of “5” are accounted for using the cost-recovery method and no income has been recorded on such loans subsequent to determining that they were impaired.

Secured Credit Facilities Our secured credit facilities are bilateral agreements we use to finance diversified pools of senior loan collateral with sufficient flexibility to accommodate our investment and asset management strategy. The facilities are uniformly structured to provide currency, index, and term-matched financing without capital markets based mark-to-market provisions. Our credit facilities are diversified across 15 counterparties, primarily consisting of top global financial institutions to minimize our counterparty risk exposure.

Therefore, the weighted-average maturity is generally allocated based on the maximum maturity date of the collateral loans, assuming all extension options are exercised by the borrower. In limited instances, the maturity date of the respective secured credit facility is used. (3) Represents the principal balance of the collateral assets. (4) Maximum maturity assumes all extension options are exercised by the borrower, however our loans may be repaid prior to such date.

The availability of funding under our secured credit facilities is based on the amount of approved collateral, which collateral is proposed by us in our discretion and approved by the respective counterparty in its discretion, resulting in a mutually agreed collateral portfolio construction. Certain structural elements of our secured credit facilities, including the limitation on recourse to us and facility economics, are influenced by the specific collateral portfolio construction of each facility, and therefore vary within and among the facilities.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	DERIVATIVE FINANCIAL INSTRUMENTS The objective of our use of derivative financial instruments is to minimize the risks and/or costs associated with our investments and/or financing transactions. These derivatives may or may not qualify as net investment, cash flow, or fair value hedges under the hedge accounting requirements of ASC 815 – “Derivatives and Hedging.” Derivatives not designated as hedges are not speculative and are used to manage our exposure to interest rate movements and other identified risks. Refer to Note 2 for additional discussion of the accounting for designated and non-designated hedges. The use of derivative financial instruments involves certain risks, including the risk that the counterparties to these contractual arrangements do not perform as agreed. To mitigate this risk, we only enter into derivative financial instruments with counterparties that have appropriate credit ratings and are major financial institutions with which we and our affiliates also have other financial relationships. Net Investment Hedges of Foreign Currency Risk Certain of our international investments expose us to fluctuations in foreign interest rates and currency exchange rates. These fluctuations may impact the value of our cash receipts and payments in terms of our functional currency, the U.S. dollar. We use foreign currency forward contracts to protect the value or fix the amount of certain investments or cash flows in terms of the U.S. dollar.

Credit-Risk Related Contingent Features We have entered into agreements with certain of our derivative counterparties that contain provisions where if we were to default on any of our indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, we may also be declared in default on our derivative obligations. In addition, certain of our agreements with our derivative counterparties require that we post collateral to secure net liability positions. As of December 31, 2023, we were in a net liability position with our counterparties. As of December 31, 2023, we had $103.5 million collateral posted with our counterparties. As of December 31, 2022, we were in a net liability position with one of our counterparties and in a net asset position with our other counterparty. As of December 31, 2022 we had collateral posted with our counterparties of $103.1 million.

Equity [Abstract]
Equity	EQUITY Stock and Stock Equivalents Authorized Capital As of December 31, 2023, we had the authority to issue up to 500,000,000 shares of stock, consisting of 400,000,000 shares of class A common stock and 100,000,000 shares of preferred stock. Subject to applicable NYSE listing requirements, our board of directors is authorized to cause us to issue additional shares of authorized stock without stockholder approval. In addition, to the extent not issued, currently authorized stock may be reclassified between class A common stock and preferred stock. We did not have any shares of preferred stock issued and outstanding as of December 31, 2023 and 2022. Class A Common Stock and Deferred Stock Units Holders of shares of our class A common stock are entitled to vote on all matters submitted to a vote of stockholders and are entitled to receive dividends authorized by our board of directors and declared by us, in all cases subject to the rights of the holders of shares of outstanding preferred stock, if any. We did not issue any class A common stock in underwritten public offerings during the year ended December 31, 2023. The following table details our issuance of class A common stock during the years ended December 31, 2022 and 2021.

(3) Represents the gross price per share issued, as well as the net proceeds per share after underwriting or sales discounts and commissions. (4) Net proceeds represent proceeds received from the underwriters less applicable transaction costs. We also issue restricted class A common stock under our stock-based incentive plans. Refer to Note 16 for additional discussion of these long-term incentive plans. In addition to our class A common stock, we also issue deferred stock units to certain members of our board of directors for services rendered. These deferred stock units are non-voting, but carry the right to receive dividends in the form of additional deferred stock units in an amount equivalent to the cash dividends paid to holders of shares of class A common stock. The following table details the movement in our outstanding shares of class A common stock, including restricted class A common stock and deferred stock units: Year Ended December 31, Common Stock Outstanding (1) 2023 2022 2021 Beginning balance 172,106,593 168,543,370 147,086,722 Issuance of class A common stock (2) 6,587 2,311,711 20,363,592 Issuance of restricted class A common stock, net (3)(4) 1,402,329 1,204,476 1,036,175 Issuance of deferred stock units 53,888 47,036 56,881 Ending balance 173,569,397 172,106,593 168,543,370 (1) Includes 359,464, 410,608, and 363,572 deferred stock units held by members of our board of directors as of December 31, 2023, 2022, and 2021, respectively. (2) Includes 6,587, 8,242, and 2,184 shares issued under our dividend reinvestment program during the years ended December 31, 2023, 2022, and 2021, respectively.

Dividend Reinvestment and Direct Stock Purchase Plan We have adopted a dividend reinvestment and direct stock purchase plan under which we registered and reserved for issuance, in the aggregate, 10,000,000 shares of class A common stock. Under the dividend reinvestment component of this plan, our class A common stockholders can designate all or a portion of their cash dividends to be reinvested in additional shares of class A common stock. The direct stock purchase component allows stockholders and new investors, subject to our approval, to purchase shares of class A common stock directly from us. During the years ended December 31, 2023, 2022, and 2021, we issued 6,587 shares, 8,242 shares, and 2,184 shares, respectively, of class A common stock under the dividend reinvestment component of the plan. As of December 31, 2023, a total of 9,974,961 shares of class A common stock remained available for issuance under the dividend reinvestment and direct stock purchase plan. At the Market Stock Offering Program As of December 31, 2023, we are party to seven equity distribution agreements, or ATM Agreements, pursuant to which we may sell, from time to time, up to an aggregate sales price of $699.1 million of our class A common stock. Sales of class A common stock made pursuant to our ATM Agreements may be made in negotiated transactions or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act of 1933, as amended. Actual sales depend on a variety of factors including market conditions, the trading price of our class A common stock, our capital needs, and our determination of the appropriate sources of funding to meet such needs. During the year ended December 31, 2023, we did not issue any shares of our class A common stock under ATM Agreements. During the year ended December 31, 2022, we issued and sold 2,303,469 shares of class A common stock under ATM Agreements, generating net proceeds totaling $70.7 million. During the year ended December 31, 2021, we issued and sold 296,901 shares of class A common stock under ATM Agreements, generating net proceeds totaling $9.9 million. As of December 31, 2023, sales of our class A common stock with an aggregate sales price of $480.9 million remained available for issuance under our ATM Agreements. Dividends We generally intend to distribute substantially all of our taxable income, which does not necessarily equal net income as calculated in accordance with GAAP, to our stockholders each year to comply with the REIT provisions of the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code. Our dividend policy remains subject to revision at the discretion of our board of directors. All distributions will be made at the discretion of our board of directors and will depend upon our taxable income, our financial condition, our maintenance of REIT status, applicable law, and other factors as our board of directors deems relevant. On December 15, 2023, we declared a dividend of $0.62 per share, or $107.4 million in aggregate, that was paid on January 16, 2024 to stockholders of record as of December 29, 2023. The following table details our dividend activity ($ in thousands, except per share data): Year Ended December 31, 2023 2022 2021 Dividends declared per share of common stock $ 2.48 $ 2.48 $ 2.48 Percent taxable as ordinary dividends 100.00 % 100.00 % 100.00 % Percent taxable as capital gain dividends — % — % — % 100.00 % 100.00 % 100.00 % Class A common stock dividends declared $ 427,862 $ 423,568 $ 383,929 Deferred stock unit dividends declared 878 945 812 $ 428,740 $ 424,513 $ 384,741 Earnings Per Share We calculate our basic and diluted earnings per share using the two-class method for all periods presented as the unvested shares of our restricted class A common stock qualify as participating securities, as defined by GAAP. These restricted shares have the same rights as our other shares of class A common stock, including participating in any dividends, and therefore have been included in our basic and diluted net income per share calculation. The shares issuable under our Convertible Notes are included in dilutive earnings per share using the if-converted method. The following table sets forth the calculation of basic and diluted net income per share of class A common stock based on the weighted-average of both restricted and unrestricted class A common stock outstanding ($ in thousands, except per share data): Year Ended December 31, 2023 2022 2021 Net income (1) $ 246,555 $ 248,642 $ 419,193 Weighted-average shares outstanding, basic and diluted (2) 172,672,038 170,631,410 151,521,941 Per share amount, basic and diluted (2) $ 1.43 $ 1.46 $ 2.77 (1) Represents net income attributable to Blackstone Mortgage Trust. (2) For the years ended December 31, 2023 and 2022, our Convertible Notes were not included in the calculation of diluted earnings per share, as the impact is antidilutive. For the year ended December 31, 2021, prior to the adoption of ASU 2020-06 “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” our convertible notes were not assessed for dilution as we had the intent and ability to settle the convertible notes in cash. Our Convertible Notes could dilute earnings per share in future periods. Refer to Note 11 for further discussion of our convertible notes. Other Balance Sheet Items Accumulated Other Comprehensive Income As of December 31, 2023, total accumulated other comprehensive income was $9.5 million, primarily representing $183.9 million of net realized and unrealized gains related to changes in the fair value of derivative instruments offset by $174.4 million of cumulative unrealized currency translation adjustments on assets and liabilities denominated in foreign currencies. As of December 31, 2022, total accumulated other comprehensive income was $10.0 million, primarily representing $259.8 million of net realized and unrealized gains related to changes in the fair value of derivative instruments offset by $249.8 million of cumulative unrealized currency translation adjustments on assets and liabilities denominated in foreign currencies. Non-Controlling Interests The non-controlling interests included on our consolidated balance sheets represent the equity interests in our Multifamily Joint Venture that are not owned by us. A portion of our Multifamily Joint Venture’s consolidated equity and results of operations are allocated to these non-controlling interests based on their pro rata ownership of our Multifamily Joint Venture. As of December 31, 2023, our Multifamily Joint Venture’s total equity was $132.0 million, of which $112.2 million was owned by us, and $19.8 million was allocated to non-controlling interests. As of December 31, 2022, our Multifamily Joint Venture’s total equity was $169.4 million, of which $144.0 million was owned by us, and $25.4 million was allocated to non-controlling interests.

Other Income and Expenses [Abstract]
Other Expenses	OTHER EXPENSES Our other expenses consist of the management and incentive fees we pay to our Manager and our general and administrative expenses. Management and Incentive Fees Pursuant to a management agreement between our Manager and us, or our Management Agreement, our Manager earns a base management fee in an amount equal to 1.50% per annum multiplied by our outstanding equity balance, as defined in the Management Agreement. In addition, our Manager is entitled to an incentive fee in an amount equal to the product of (i) 20% and (ii) the excess of (a) our Core Earnings (as defined in our Management Agreement) for the previous 12-month period over (b) an amount equal to 7.00% per annum multiplied by our outstanding Equity, provided that our Core Earnings over the prior three-year period is greater than zero. Core Earnings, as defined in our Management Agreement, is generally equal to our GAAP net income (loss), including realized gains and losses not otherwise recognized in current period GAAP net income (loss), and excluding (i) non-cash equity compensation expense, (ii) depreciation and amortization, (iii) unrealized gains (losses), (iv) net income (loss) attributable to our legacy portfolio, (v) certain non-cash items, and (vi) incentive management fees. During the years ended December 31, 2023, 2022 and 2021, we incurred $74.8 million, $73.0 million and $64.2 million respectively, of management fees payable to our manager. In addition, during the years ended December 31, 2023, 2022 and 2021, we incurred $44.2 million, $37.3 million and $24.3 million respectively, of incentive fees payable to our Manager. As of December 31, 2023 and 2022 we had accrued management and incentive fees payable to our Manager of $26.3 million and $33.8 million, respectively.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES We have elected to be taxed as a REIT under the Internal Revenue Code for U.S. federal income tax purposes. We generally must distribute annually at least 90% of our net taxable income, subject to certain adjustments and excluding any net capital gain, in order for U.S. federal income tax not to apply to our earnings. To the extent that we satisfy this distribution requirement, but distribute less than 100% of our net taxable income, we will be subject to U.S. federal income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible excise tax if the actual amount that we pay out to our stockholders in a calendar year is less than a minimum amount specified under U.S. federal tax laws. Our qualification as a REIT also depends on our ability to meet various other requirements imposed by the Internal Revenue Code, which relate to organizational structure, diversity of stock ownership, and certain restrictions with regard to the nature of our assets and the sources of our income. Even if we qualify as a REIT, we may be subject to certain U.S. federal income and excise taxes and state and local taxes on our income and assets. If we fail to maintain our qualification as a REIT for any taxable year, we may be subject to material penalties as well as federal, state, and local income tax on our taxable income at regular corporate rates and we would not be able to qualify as a REIT for the subsequent four full taxable years. As of December 31, 2023 and 2022, we were in compliance with all REIT requirements. Securitization transactions could result in the creation of taxable mortgage pools for federal income tax purposes. As a REIT, so long as we own 100% of the equity interests in a taxable mortgage pool, we generally would not be adversely affected by the characterization of the securitization as a taxable mortgage pool. Certain categories of stockholders, however, such as foreign stockholders eligible for treaty or other benefits, stockholders with net operating losses, and certain tax-exempt stockholders that are subject to unrelated business income tax, or UBTI, could be subject to increased taxes on a portion of their dividend income from us that is attributable to the taxable mortgage pool. We have not made UBTI distributions to our common stockholders and do not intend to make such UBTI distributions in the future. During the years ended December 31, 2023, 2022 and 2021, we recorded a current income tax provision of $5.4 million, $3.0 million, and $423,000, respectively, primarily related to activities of our U.S. and foreign taxable subsidiaries and various state and local taxes. We did not have any deferred tax assets or liabilities as of December 31, 2023 or December 31, 2022. We have net operating losses, or NOLs, generated by our predecessor business that may be carried forward and utilized in current or future periods. As a result of our issuance of 25,875,000 shares of class A common stock in May 2013, the availability of our NOLs is generally limited to $2.0 million per annum by change of control provisions promulgated by the Internal Revenue Service with respect to the ownership of Blackstone Mortgage Trust. As of December 31, 2023, we had estimated NOLs of $159.0 million that will expire in 2029, unless they are utilized by us prior to expiration. Previously, we recorded a full valuation allowance against such NOLs as we expected that they would expire unutilized. However, although uncertain, we may utilize a portion of NOLs prior to expiration. We do not expect the utilization of NOLs to have a material impact on our consolidated financial statements. We have recorded a full valuation allowance against such NOLs as it is probable that they will expire unutilized.

Stock-Based Incentive Plans	STOCK-BASED INCENTIVE PLANS We are externally managed by our Manager and do not currently have any employees. However, as of December 31, 2023, our Manager, certain individuals employed by an affiliate of our Manager, and certain members of our board of directors were compensated, in part, through our issuance of stock-based instruments. Under our two current stock incentive plans, a maximum of 10,400,000 shares of our class A common stock may be issued to our Manager, our directors and officers, and certain employees of affiliates of our Manager. As of December 31, 2023, there were 7,754,648 shares available under our current stock incentive plans. Prior to the adoption and shareholder approval of our new stock incentive plans in June 2022, we had stock-based incentive awards outstanding under nine stock incentive plans. In connection with the adoption of our new stock incentive plans, we consolidated all outstanding deferred stock units, or DSUs, under the new plans and retired the seven remaining historical plans. As such, no new awards may be issued under these expired plans, although our 2018 plans will continue to govern outstanding awards, other than DSUs, previously issued thereunder until such awards become vested or expire. The following table details the movement in our outstanding shares of restricted class A common stock and the weighted-average grant date fair value per share: Restricted Class A Common Stock Weighted-Average Grant Date Fair Value Per Share Balance as of December 31, 2021 1,706,121 $ 31.19 Granted 1,244,131 26.92 Vested (1,026,813) 32.06 Forfeited (39,655) 30.76 Balance as of December 31, 2022 1,883,784 $ 27.90 Granted 1,417,806 22.07 Vested (1,105,932) 27.35 Forfeited (15,477) 24.55 Balance as of December 31, 2023 2,180,181 $ 24.41 These shares generally vest in installments over a period of three years, pursuant to the terms of the respective award agreements and the terms of our current benefit plans.

As of December 31, 2023, total unrecognized compensation cost relating to unvested share-based compensation arrangements was $51.2 million based on the grant date fair value of shares granted. This cost is expected to be recognized over a weighted-average period of 1.2 years from December 31, 2023.

Related Party Transactions [Abstract]
Transactions With Related Parties	TRANSACTIONS WITH RELATED PARTIES We are managed by our Manager pursuant to the Management Agreement, the current term of which expires on December 19, 2024, and will be automatically renewed for a one-year term upon such date and each anniversary thereafter unless earlier terminated. As of December 31, 2023 and 2022, our consolidated balance sheets included $26.3 million and $33.8 million of accrued management and incentive fees payable to our Manager, respectively. During the years ended December 31, 2023, 2022, and 2021, we paid aggregate management and incentive fees of $126.6 million, $104.8 million, and $79.3 million, respectively, to our Manager. In addition, during the years ended December 31, 2023, 2022, and 2021, we incurred expenses of $3.4 million, $896,000, and $601,000, respectively, that were paid by our Manager and will be reimbursed by us. As of December 31, 2023, our Manager held 1,311,056 shares of unvested restricted class A common stock, which had an aggregate grant date fair value of $32.2 million, and vest in installments over three years from the date of issuance. During the years ended December 31, 2023, 2022, and 2021, we recorded non-cash expenses related to shares held by our Manager of $14.6 million, $16.6 million, and $15.3 million respectively. Refer to Note 16 for further details on our restricted class A common stock. As of December 31, 2023, our Manager, its affiliates, Blackstone employees, and our directors held an aggregate 12,531,542 shares, or 7.2%, of our class A common stock, of which 7,582,044 shares, or 4.4%, were held by subsidiaries of Blackstone, including our Manager. Additionally, our directors held 359,464 of deferred stock units as of December 31, 2023. CT Investment Management Co., LLC, or CTIMCO, an affiliate of our Manager, is the special servicer of the CLOs. CTIMCO did not earn any special servicing fees related to the CLOs during the years ended December 31, 2023, 2022, and 2021. During the year ended December 31, 2021, we originated three loans whereby the respective borrowers engaged an affiliate of our Manager to act as title insurance agent in connection with these transactions. We did not incur any expenses or receive any revenues as a result of these transactions. There were no similar transactions during the years ended December 31, 2023 and 2022. We have engaged Revantage Corporate Services, LLC and Revantage Global Services Europe S.à r.l., portfolio companies owned by Blackstone-advised investment vehicles, to provide, as applicable, corporate support services, operational services, and management services. These services are provided on an allocated cost basis. Additionally, we have engaged an affiliate of our Manager to provide internal audit services. During the years ended December 31, 2023, 2022 and 2021, we incurred $658,000, $524,000, and $385,000, respectively, of expenses for various administrative and operations services to these service providers that are affiliates of our Manager. Affiliates of our Manager own an interest in the controlling entity of BTIG, LLC, or BTIG. We utilized BTIG as a broker to engage third-parties to facilitate our repurchase of our Senior Secured Notes. During the year ended December 31, 2023, we repurchased $500,000 of our Senior Secured Notes utilizing BTIG as a broker. BTIG received aggregate fees of $1,000 in such capacity. The fees were on terms equivalent to those of other brokers under similar arrangements. BTIG did not act as a broker to engage third-parties to repurchase our Senior Secured Notes during the years ended December 31, 2022 or 2021. Additionally, we engaged BTIG as a sales agent to sell shares of our class A common stock under our ATM Agreements. During the year ended December 31, 2022, BTIG received aggregate fees of $191,000 in such capacity. The fees paid were on terms equivalent to those of other sales agents engaged to sell shares under our ATM agreements. BTIG did not sell any shares under our ATM agreements in the years ended December 31, 2023 or 2021. In the first quarter of 2019, we originated £240.1 million of a total £490.0 million senior loan to a borrower that is wholly owned by a Blackstone-advised investment vehicle. The loan terms were negotiated by our third-party co-lender, and we forgo all non-economic rights under the loan, including voting rights, so long as a Blackstone-advised investment vehicle controls the borrower. In the second quarter of 2023, the loan was modified to include, among other changes, an extension of the loan's maturity date, an additional borrower equity contribution and partial repayment, and an increase in the loan’s contractual interest rate (a portion of which is paid-in-kind). The terms of the modification were negotiated by our third-party co-lender, and we agreed to the modification on such terms. In the second quarter of 2022, we participated in A$1.3 billion, or 24.5%, of an aggregate A$5.4 billion senior loan that was originated by an unaffiliated third party to a borrower that is wholly-owned by Blackstone-advised investment vehicles. Another Blackstone-advised investment vehicle participated in an additional A$1.3 billion, or 24.5%, of the loan. We will forgo all non-economic rights under the loan, including voting rights, so long as we are an affiliate of the borrower. The senior loan terms were negotiated by a third-party without our involvement and our 24.5% interest in the senior loan was made on such market terms. In the second quarter of 2022, we co-originated £250.0 million of an aggregate £500.0 million senior loan to an unaffiliated third-party. A Blackstone-advised investment vehicle co-originated the additional pari passu £250.0 million of the loan. In the second and fourth quarters of 2022, a Blackstone-advised investment vehicle acquired an aggregate $33.0 million participation, or 4%, of the aggregate B-4 Term Loan as a part of a broad syndication lead-arranged by JP Morgan. Blackstone Securities Partners L.P., an affiliate of our Manager, was engaged as a book-runner for the transaction and received aggregate fees of $825,000 in such capacity. Both of these transactions were on terms equivalent to those of unaffiliated parties. In the fourth quarter of 2021, we issued $400.0 million aggregate principal amount of 3.75% Senior Secured Notes. The Senior Secured Notes were issued at par and have a maturity date of January 15, 2027. Blackstone Securities Partners L.P., an affiliate of our Manager, participated in the offering of the Senior Secured Notes and received compensation of $400,000 in connection therewith. This transaction was on terms equivalent to those of unaffiliated parties. In the second quarter of 2021 and 2020, certain Blackstone-advised investment vehicles acquired an aggregate $20.0 million participation, or 15%, of the initial aggregate B-3 Term Loan as a part of a broad syndication lead-arranged by JP Morgan. Blackstone Securities Partners L.P., an affiliate of our Manager, was engaged as a book-runner for the transaction and received aggregate fees of $350,000 in such capacity. Both of these transactions were on terms equivalent to those of unaffiliated parties. In the first quarter of 2021, a Blackstone-advised investment vehicle acquired an aggregate $5.5 million participation, or 3%, of the $200.0 million increase to our B-1 Term Loan as a part of a broad syndication lead-arranged by JP Morgan. Blackstone Securities Partners L.P., an affiliate of our Manager, was engaged as a book-runner for the transaction and received aggregate fees of $200,000 in such capacity. Both of these transactions were on terms equivalent to those of unaffiliated parties.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Unfunded Commitments Under Loans Receivable As of December 31, 2023, we had aggregate unfunded commitments of $2.4 billion across 99 loans receivable, and $1.3 billion of committed or identified financings for those commitments, resulting in net unfunded commitments of $1.2 billion. The unfunded loan commitments comprise funding for capital expenditures and construction, leasing costs, and interest and carry costs. Loan funding commitments are generally subject to certain conditions, including, without limitation, the progress of capital projects, leasing, and cash flows at the properties securing our loans. Therefore, the exact timing and amounts of such future loan fundings are uncertain and will depend on the current and future performance of the underlying collateral assets. We expect to fund our loan commitments over the remaining term of the related loans, which have a weighted-average future funding period of 2.6 years. Principal Debt Repayments Our contractual principal debt repayments as of December 31, 2023 were as follows ($ in thousands): Year Secured Debt (1) Asset-Specific Debt (1) Term Loans (2) Senior Secured Notes Convertible Notes (3) Total (4) 2024 $ 2,445,576 $ — $ 21,997 $ — $ — $ 2,467,573 2025 1,577,980 825,687 21,997 — — 2,425,664 2026 4,298,806 — 1,302,575 — — 5,601,381 2027 3,153,609 — 8,258 366,090 300,000 3,827,957 2028 500,105 — 8,256 — — 508,361 Thereafter 720,982 178,410 772,138 — — 1,671,530 Total obligation $ 12,697,058 $ 1,004,097 $ 2,135,221 $ 366,090 $ 300,000 $ 16,502,466 (1) Our secured debt and asset-specific debt agreements are generally term-matched to their underlying collateral. Therefore, the allocation of payments under such agreements is generally allocated based on the maximum maturity date of the collateral loans, assuming all extension options are exercised by the borrower. In limited instances, the maturity date of the respective debt agreement is used. (2) The Term Loans are partially amortizing, with an amount equal to 1.0% per annum of the initial principal balance due in quarterly installments. Refer to Note 9 for further details on our Term Loans. (3) Reflects the outstanding principal balance of Convertible Notes, excluding any potential conversion premium. Refer to Note 11 for further details on our Convertible Notes. (4) Total does not include $2.5 billion of consolidated securitized debt obligations, $1.1 billion of non-consolidated senior interests, and $337.7 million of loan participations sold, as the satisfaction of these liabilities will not require cash outlays from us. Board of Directors’ Compensation As of December 31, 2023, of the ten members of our board of directors, our six independent directors are entitled to annual compensation of $210,000 each, of which $95,000 is paid in cash and $115,000 is paid in the form of deferred stock units or, at their election, shares of restricted common stock. As of December 31, 2023, the other four board members, including our chairman and our chief executive officer, are not compensated by us for their service as directors. In addition, (i) the chairs of our audit, compensation, and corporate governance committees receive additional annual cash compensation of $20,000, $15,000, and $10,000, respectively and (ii) the members of our audit and investment risk management committees receive additional annual cash compensation of $10,000 and $7,500, respectively.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2023
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, and include, on a consolidated basis, our accounts, the accounts of our wholly-owned subsidiaries, majority-owned subsidiaries, and variable interest entities, or VIEs, of which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation.
Principles of Consolidation	Principles of Consolidation We consolidate all entities that we control through either majority ownership or voting rights. In addition, we consolidate all VIEs of which we are considered the primary beneficiary. VIEs are defined as entities in which equity investors (i) do not have an interest with the characteristics of a controlling financial interest and/or (ii) do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The entity that consolidates a VIE is known as its primary beneficiary and is generally the entity with (i) the power to direct the activities that most significantly affect the VIE’s economic performance and (ii) the right to receive benefits from the VIE or the obligation to absorb losses of the VIE that could be significant to the VIE.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may ultimately differ materially from those estimates.
Revenue Recognition	Revenue Recognition Interest income from our loans receivable portfolio is recognized over the life of each investment using the effective interest method and is recorded on the accrual basis. Recognition of fees, premiums, and discounts associated with these investments is deferred and recorded over the term of the loan as an adjustment to yield. Income accrual is generally suspended for loans at the earlier of the date at which payments become 90 days past due or when, in our opinion, recovery of income and principal becomes doubtful. Interest received is then recorded as income or as a reduction in the amortized cost basis, based on the specific facts and circumstances, until accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. In addition, for loans we originate, the related origination expenses are deferred and recognized as a reduction to interest income, however expenses related to loans we acquire are included in general and administrative expenses as incurred.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents represent cash held in banks and liquid investments with original maturities of three months or less. We may have bank balances in excess of federally insured amounts; however, we deposit our cash and cash equivalents with high credit-quality institutions to minimize credit risk exposure. We have not experienced, and do not expect, any losses on our cash or cash equivalents. As of both December 31, 2023 and 2022, we had no restricted cash on our consolidated balance sheets. Through our subsidiaries, we have oversight of certain servicing accounts held with third-party servicers, or Servicing Accounts, which relate to borrower escrows and other cash balances aggregating $640.6 million and $459.6 million as of December 31, 2023 and 2022, respectively. This cash is maintained in segregated bank accounts, and these amounts are not included in the assets and liabilities presented in our consolidated balance sheets. Cash in these Servicing Accounts will be transferred by the respective third-party servicer to the borrower or us under the terms of the applicable loan agreement upon occurrence of certain future events. We do not generate any revenue or incur any expenses as a result of these Servicing Accounts.
Loans Receivable	Loans Receivable
Current Expected Credit Losses Reserve	Current Expected Credit Losses Reserve The current expected credit loss, or CECL, reserve required under the Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 326 “Financial Instruments – Credit Losses,” or ASC 326, reflects our current estimate of potential credit losses related to our loans included in our consolidated balance sheets. Changes to the CECL reserves are recognized through net income on our consolidated statements of operations. While ASC 326 does not require any particular method for determining the CECL reserves, it does specify the reserves should be based on relevant information about past events, including historical loss experience, current portfolio and market conditions, and reasonable and supportable forecasts for the duration of each respective loan. In addition, other than a few narrow exceptions, ASC 326 requires that all financial instruments subject to the CECL model have some amount of loss reserve to reflect the GAAP principal underlying the CECL model that all loans and similar assets have some inherent risk of loss, regardless of credit quality, subordinate capital, or other mitigating factors. We estimate our CECL reserves primarily using the Weighted-Average Remaining Maturity, or WARM method, which has been identified as an acceptable loss-rate method for estimating CECL reserves in FASB Staff Q&A Topic 326, No. 1. The WARM method requires us to reference historic loan loss data across a comparable data set and apply such loss rate to each of our loans over their expected remaining term, taking into consideration expected economic conditions over the relevant timeframe. We apply the WARM method for the majority of our loan portfolio, which consists of loans that share similar risk characteristics. In certain instances, for loans with unique risk characteristics, we may instead use a probability-weighted model that considers the likelihood of default and expected loss given default for each such individual loan. Application of the WARM method to estimate CECL reserves requires judgment, including (i) the appropriate historical loan loss reference data, (ii) the expected timing and amount of future loan fundings and repayments, and (iii) the current credit quality of our portfolio and our expectations of performance and market conditions over the relevant time period. To estimate the historic loan losses relevant to our portfolio, we have augmented our historical loan performance, with market loan loss data licensed from Trepp LLC. This database includes commercial mortgage-backed securities, or CMBS, issued since January 1, 1999 through November 30, 2023. Within this database, we focused our historical loss reference calculations on the most relevant subset of available CMBS data, which we determined based on loan metrics that are most comparable to our loan portfolio including asset type, geography, and origination loan-to-value, or LTV. We believe this CMBS data, which includes month-over-month loan and property performance, is the most relevant, available, and comparable dataset to our portfolio. Our loans typically include commitments to fund incremental proceeds to our borrowers over the life of the loan. These future funding commitments are also subject to the CECL model. The CECL reserve related to future loan fundings is recorded as a component of other liabilities on our consolidated balance sheets. This CECL reserve is estimated using the same process outlined above for our outstanding loan balances, and changes in this component of the CECL reserve will similarly impact our consolidated net income. For both the funded and unfunded portions of our loans, we consider our internal risk rating of each loan as the primary credit quality indicator underlying our assessment. The CECL reserves are measured on a collective basis wherever similar risk characteristics exist within a pool of similar assets. We have identified the following pools and measure the reserve for credit losses using the following methods: • U.S. Loans : WARM method that incorporates a subset of historical loss data, expected weighted-average remaining maturity of our loan pool, and an economic view. • Non-U.S. Loans : WARM method that incorporates a subset of historical loss data, expected weighted-average remaining maturity of our loan pool, and an economic view. • Unique Loans : a probability of default and loss given default model, assessed on an individual basis. • Impaired Loans : impairment is indicated when it is deemed probable that we will not be able to collect all amounts due to us pursuant to the contractual terms of the loan. Determining that a loan is impaired requires significant judgment from management and is based on several factors including (i) the underlying collateral performance, (ii) discussions with the borrower, (iii) borrower events of default, and (iv) other facts that impact the borrower’s ability to pay the contractual amounts due under the terms of the loan. If a loan is determined to be impaired, we record the impairment as a component of our CECL reserves by applying the practical expedient for collateral dependent loans. The CECL reserves are assessed on an individual basis for these loans by comparing the estimated fair value of the underlying collateral, less costs to sell, to the book value of the respective loan. These valuations require significant judgments, which include assumptions regarding capitalization rates, discount rates, leasing, creditworthiness of major tenants, occupancy rates, availability and cost of financing, exit plan, loan sponsorship, actions of other lenders, and other factors deemed relevant by us. Actual losses, if any, could ultimately differ materially from these estimates. We only expect to charge-off the impairment losses in our consolidated financial statements prepared in accordance with GAAP if and when such amounts are deemed non-recoverable. This is generally at the time a loan is repaid or foreclosed. However, non-recoverability may also be concluded if, in our determination, it is nearly certain that all amounts due will not be collected. Contractual Term and Unfunded Loan Commitments Expected credit losses are estimated over the contractual term of each loan, adjusted for expected repayments. As part of our quarterly review of our loan portfolio, we assess the expected repayment date of each loan, which is used to determine the contractual term for purposes of computing our CECL reserves. Additionally, the expected credit losses over the contractual period of our loans are subject to the obligation to extend credit through our unfunded loan commitments. The CECL reserve for unfunded loan commitments is adjusted quarterly, as we consider the expected timing of future funding obligations over the estimated life of the loan. The considerations in estimating our CECL reserve for unfunded loan commitments are similar to those used for the related outstanding loans receivable. Credit Quality Indicator Our risk rating is our primary credit quality indicator in assessing our current expected credit loss reserve. We perform a quarterly risk review of our portfolio of loans, and assign each loan a risk rating based on a variety of factors, including, without limitation, origination LTV, debt yield, property type, geographic and local market dynamics, physical condition, cash flow volatility, leasing and tenant profile, loan structure and exit plan, and project sponsorship. Based on a 5-point scale, our loans are rated “l” through “5,” from less risk to greater risk, relative to our loan portfolio in the aggregate, which ratings are defined as follows: 1 - Very Low Risk 2 - Low Risk 3 - Medium Risk 4 - High Risk/Potential for Loss: A loan that has a risk of realizing a principal loss. 5 - Impaired/Loss Likely: A loan that has a very high risk of realizing a principal loss or has otherwise incurred a principal loss. Estimation of Economic Conditions
Derivative Financial Instruments	Derivative Financial Instruments We classify all derivative financial instruments as either other assets or other liabilities on our consolidated balance sheets at fair value. On the date we enter into a derivative contract, we designate each contract as (i) a hedge of a net investment in a foreign operation, or net investment hedge, (ii) a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability, or cash flow hedge, (iii) a hedge of a recognized asset or liability, or fair value hedge, or (iv) a derivative instrument not to be designated as a hedging derivative, or non-designated hedge. For all derivatives other than those designated as non-designated hedges, we formally document our hedge relationships and designation at the contract’s inception. This documentation includes the identification of the hedging instruments and the hedged items, its risk management objectives, strategy for undertaking the hedge transaction and our evaluation of the effectiveness of its hedged transaction. On a quarterly basis, we also formally assess whether the derivative we designated in each hedging relationship is expected to be, and has been, highly effective in offsetting changes in the value or cash flows of the hedged items. If it is determined that a derivative is not highly effective at hedging the designated exposure, hedge accounting is discontinued and the changes in fair value of the instrument are included in net income prospectively. Our net investment hedges are assessed using a method based on changes in spot exchange rates. Gains and losses, representing hedge components excluded from the assessment of effectiveness, are recognized in interest income on our consolidated statements of operations over the contractual term of our net investment hedges on a systematic and rational basis, as documented at hedge inception in accordance with our accounting policy election. All other changes in the fair value of our derivative instruments that qualify as hedges are reported as a component of accumulated other comprehensive income (loss) on our consolidated financial statements. Deferred gains and losses are reclassified out of accumulated other comprehensive income (loss) and into net income in the same period or periods during which the hedged transaction affects earnings, and are presented in the same line item as the earnings effect of the hedged item. For cash flow hedges, this is typically when the periodic swap settlements are made, while for net investment hedges, this occurs when the hedged item is sold or substantially liquidated. To the extent a derivative does not qualify for hedge accounting and is deemed a non-designated hedge, the changes in its fair value are included in net income concurrently.
Secured Debt and Asset-Specific Debt	Secured Debt and Asset-Specific Debt We record investments financed with secured debt or asset-specific debt as separate assets and the related borrowings under any secured debt or asset-specific debt are recorded as separate liabilities on our consolidated balance sheets. Interest income earned on the investments and interest expense incurred on the secured debt or asset-specific debt are reported separately on our consolidated statements of operations.
Loan Participations Sold	Loan Participations Sold
Term Loans and Senior Secured Notes	Term Loans We record our term loans as liabilities on our consolidated balance sheets. Where applicable, any issue discount or transaction expenses are deferred and amortized through the maturity date of the term loans as additional non-cash interest expense. Senior Secured Notes We record our senior secured notes as liabilities on our consolidated balance sheets. Where applicable, any issue discount or transaction expenses are deferred and amortized through the maturity date of the senior secured notes as additional non-cash interest expense.
Convertible Notes	Convertible Notes Convertible note proceeds, unless issued with a substantial premium or an embedded conversion feature, are classified as debt. Additionally, shares issuable under our convertible notes are included in diluted earnings per share in our consolidated financial statements, if the effect is dilutive, using the if-converted method, regardless of settlement intent. Where applicable, any issue discount or transaction expenses are deferred and amortized through the maturity date of the convertible notes as additional non-cash interest expense.

Fair Value of Financial Instruments	Fair Value of Financial Instruments The “Fair Value Measurements and Disclosures” Topic o f the FASB, or ASC 820, defines fair value, establishes a framework for measuring fair value, and requires certain disclosures about fair value measurements under GAAP. Specifically, this guidance defines fair value based on exit price, or the price that would be received upon the sale of an asset or the transfer of a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a fair value hierarchy that prioritizes and ranks the level of market price observability used in measuring financial instruments. Market price observability is affected by a number of factors, including the type of financial instrument, the characteristics specific to the financial instrument, and the state of the marketplace, including the existence and transparency of transactions between market participants. Financial instruments with readily available quoted prices in active markets generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. Financial instruments measured and reported at fair value are classified and disclosed based on the observability of inputs used in the determination, as follows: • Level 1: Generally includes only unadjusted quoted prices that are available in active markets for identical financial instruments as of the reporting date. • Level 2: Pricing inputs include quoted prices in active markets for similar instruments, quoted prices in less active or inactive markets for identical or similar instruments where multiple price quotes can be obtained, and other observable inputs, such as interest rates, yield curves, credit risks, and default rates. • Level 3: Pricing inputs are unobservable for the financial instruments and include situations where there is little, if any, market activity for the financial instrument. These inputs require significant judgment or estimation by management of third-parties when determining fair value and generally represent anything that does not meet the criteria of Levels 1 and 2. Certain of our other assets are reported at fair value, as of quarter-end, either (i) on a recurring basis or (ii) on a nonrecurring basis, as a result of impairment or other events. Our assets that are recorded at fair value are discussed further in Note 17. We generally value our assets recorded at fair value by either (i) discounting expected cash flows based on assumptions regarding the collection of principal and interest and estimated market rates, or (ii) obtaining assessments from third-parties. For collateral-dependent loans that are identified as impaired, we measure impairment by comparing our estimation of the fair value of the underlying collateral, less costs to sell, to the book value of the respective loan. These valuations require significant judgments, which include assumptions regarding capitalization rates, discount rates, leasing, creditworthiness of major tenants, occupancy rates, availability and cost of financing, exit plan, loan sponsorship, actions of other lenders, and other factors. As of December 31, 2023, we had an aggregate $417.7 million asset-specific CECL reserve related to 13 of our loans receivable with an aggregate amortized cost basis of $1.9 billion, net of cost-recovery proceeds. The CECL reserve was recorded based on our estimation of the fair value of the loans' aggregate underlying collateral as of December 31, 2023. These loans receivable are therefore measured at fair value on a nonrecurring basis using significant unobservable inputs, and are classified as Level 3 assets in the fair value hierarchy. We estimated the fair value of these loans receivable by considering a variety of inputs including property performance, market data, and comparable sales, as applicable. The significant unobservable inputs used include the exit capitalization rate assumption used to forecast the future sale price of the underlying real estate collateral, which ranged from 5.25% to 8.00%, and the unlevered discount rate, which ranged from 7.28% to 11.00%. We are also required by GAAP to disclose fair value information about financial instruments, which are not otherwise reported at fair value in our consolidated balance sheet, to the extent it is practicable to estimate a fair value for those instruments. These disclosure requirements exclude certain financial instruments and all non-financial instruments. The following methods and assumptions are used to estimate the fair value of each class of financial instruments, for which it is practicable to estimate that value: • Cash and cash equivalents: The carrying amount of cash and cash equivalents approximates fair value. • Loans receivable, net: The fair values of these loans were estimated using a discounted cash flow methodology, taking into consideration various factors including capitalization rates, discount rates, leasing, credit worthiness of major tenants, occupancy rates, availability and cost of financing, exit plan, loan sponsorship, actions of other lenders, and other factors. • Derivative financial instruments: The fair value of our foreign currency and interest rate contracts was estimated using advice from a third-party derivative specialist, based on contractual cash flows and observable inputs comprising foreign currency rates and credit spreads. • Secured debt, net: The fair value of these instruments was estimated based on the rate at which a similar credit facility would currently be priced. • Securitized debt obligations, net: The fair value of these instruments was estimated by utilizing third-party pricing service providers. In determining the value of a particular investment, pricing service providers may use broker-dealer quotations, reported trades, or valuation estimates from their internal pricing models to determine the reported price. • Asset-specific debt, net: The fair value of these instruments was estimated based on the rate at which a similar agreement would currently be priced. • Loan participations sold, net: The fair value of these instruments was estimated based on the value of the related loan receivable asset. • Term loans, net: The fair value of these instruments was estimated by utilizing third-party pricing service providers. In determining the value of a particular investment, pricing service providers may use broker-dealer quotations, reported trades, or valuation estimates from their internal pricing models to determine the reported price. • Senior secured notes, net: The fair value of these instruments was estimated by utilizing third-party pricing service providers. In determining the value of a particular investment, pricing service providers may use broker-dealer quotations, reported trades, or valuation estimates from their internal pricing models to determine the reported price. •
Income Taxes	Income Taxes Our financial results generally do not reflect provisions for current or deferred income taxes on our REIT taxable income. We believe that we operate in a manner that will continue to allow us to be taxed as a REIT and, as a result, we generally do not expect to pay substantial corporate level taxes other than those payable by our taxable REIT subsidiaries. If we were to fail to meet these requirements, we may be subject to federal, state, and local income tax on current and past income, and penalties. Refer to Note 15 for additional information.
Stock-Based Compensation	Stock-Based Compensation Our stock-based compensation consists of awards issued to our Manager, certain individuals employed by an affiliate of our Manager, and certain members of our board of directors that vest over the life of the awards, as well as deferred stock units issued to certain members of our board of directors. Stock-based compensation expense is recognized for these awards in net income on a variable basis over the applicable vesting period of the awards, based on the value of our class A common stock. Refer to Note 16 for additional information.
Earnings per Share	Earnings per Share Basic earnings per share, or Basic EPS, is computed in accordance with the two-class method and is based on (i) the net earnings allocable to our class A common stock, including restricted class A common stock and deferred stock units, divided by (ii) the weighted-average number of shares of our class A common stock, including restricted class A common stock and deferred stock units outstanding during the period. Our restricted class A common stock is considered a participating security, as defined by GAAP, and has been included in our Basic EPS under the two-class method as these restricted shares have the same rights as our other shares of class A common stock, including participating in any gains or losses.

Recent Accounting Pronouncements	Recent Accounting Pronouncements In December 2023, the FASB issued Accounting Standards Update, or ASU, 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” or ASU 2023-09. ASU 2023-09 requires additional disaggregated disclosures on the entity’s effective tax rate reconciliation and additional details on income taxes paid. ASU 2023-09 is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2024 and early adoption is permitted. We do not expect the adoption of ASU 2023-09 to have a material impact on our consolidated financial statements. In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” or ASU 2023-07. ASU 2023-07 enhances the disclosures required for reportable segments on an annual and interim basis. ASU 2023-07 is effective on a retrospective basis for annual periods beginning after December 15, 2023, for interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. We do not expect the adoption of ASU 2023-07 to have a material impact on our consolidated financial statements. In March 2022, the FASB issued ASU, 2022-02 “Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures,” or ASU 2022-02. ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings and requires disclosure of current-period gross write-offs by year of loan origination. Additionally, ASU 2022-02 updates the accounting for credit losses under ASC 326 and adds enhanced disclosures with respect to loan refinancings and restructurings in the form of principal forgiveness, interest rate concessions, other-than-insignificant payment delays, or term extensions when the borrower is experiencing financial difficulties. ASU 2022-02 is effective for fiscal years beginning after December 15, 2022 and early adoption is permitted. The amendments should be applied prospectively, however for the recognition and measurement of troubled debt restructurings, the entity has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. The adoption of ASU 2022-02 on January 1, 2023 did not have a material impact on our consolidated financial statements.

Overall Statistics for Loans Receivable Portfolio	The following table details overall statistics for our loans receivable portfolio ($ in thousands): December 31, 2023 December 31, 2022 Number of loans 178 203 Principal balance $ 23,923,719 $ 25,160,343 Net book value $ 23,210,076 $ 24,691,743 Unfunded loan commitments (1) $ 2,430,664 $ 3,806,153 Weighted-average cash coupon (2) + 3.37 % + 3.44 % Weighted-average all-in yield (2) + 3.71 % + 3.84 % Weighted-average maximum maturity (years) (3) 2.4 3.1 (1) Unfunded commitments will primarily be funded to finance our borrowers’ construction or development of real estate-related assets, capital improvements of existing assets, or lease-related expenditures. These commitments will generally be funded over the term of each loan, subject in certain cases to an expiration date. (2) The weighted-average cash coupon and all-in yield are expressed as a spread over the relevant floating benchmark rates, which include SOFR, USD LIBOR, SONIA, EURIBOR, and other indices, as applicable to each loan. As of December 31, 2023 99% of our loans by principal balance earned a floating rate of interest, primarily indexed to SOFR, and the remaining 1% of our loans earned a fixed rate of interest. As of December 31, 2022, substantially all of our loans by principal balance earned a floating rate of interest, primarily indexed to SOFR and USD LIBOR. Floating rate exposure as of December 31, 2023 includes an interest rate swap we entered into with a notional amount of $229.9 million that effectively converts certain of our fixed rate loan exposure to floating rate exposure. In addition to cash coupon, all-in yield includes the amortization of deferred origination and extension fees, loan origination costs, and purchase discounts, as well as the accrual of exit fees. Excludes loans accounted for under the cost-recovery method. (3)
