Accounting Policies [Abstract]
Balance Sheet Presentation of Securitization Variable Interest Entities	Balance Sheet Presentation of Securitization Variable Interest Entities We operate investment businesses that acquire unrated, investment grade and non-investment grade rated CMBS and RMBS. These securities represent interests in securitization structures (commonly referred to as special purpose entities, or “SPEs”). These SPEs are structured as pass through entities that receive principal and interest on the underlying collateral and distribute those payments to the certificate holders. Under accounting principles generally accepted in the United States of America (“GAAP”), SPEs typically qualify as VIEs. These are entities that, by design, either (1) lack sufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties, or (2) have equity investors that do not have the ability to make significant decisions relating to the entity’s operations through voting rights, or do not have the obligation to absorb the expected losses, or do not have the right to receive the residual returns of the entity. Because we often serve as the special servicer or servicing administrator of the trusts in which we invest, or we have the ability to remove and replace the special servicer without cause, consolidation of these structures is required pursuant to GAAP as outlined in detail below. This results in a consolidated balance sheet which presents the gross assets and liabilities of the VIEs. The assets and other instruments held by these VIEs are restricted and can only be used to fulfill the obligations of the entity. Additionally, the obligations of the VIEs do not have any recourse to the general credit of any other consolidated entities, nor to us as the consolidator of these VIEs. The VIE liabilities initially represent investment securities on our balance sheet (pre-consolidation). Upon consolidation of these VIEs, our associated investment securities are eliminated, as is the interest income related to those securities. Similarly, the fees we earn in our roles as special servicer of the bonds issued by the consolidated VIEs or as collateral administrator of the consolidated VIEs are also eliminated. Finally, a portion of the identified servicing intangible associated with the eliminated fee streams is eliminated in consolidation.
Basis of Accounting and Principles of Consolidation	Basis of Accounting and Principles of Consolidation The accompanying consolidated financial statements include our accounts and those of our consolidated subsidiaries and VIEs. Intercompany amounts have been eliminated in consolidation. Entities not deemed to be VIEs are consolidated if we own a majority of the voting securities or interests or hold the general partnership interest, except in those instances in which the minority voting interest owner or limited partner can remove us as general partner without cause, dissolve the partnership without cause or effectively participate through substantive participative rights. Substantive participative rights include the ability to select, terminate and set compensation of the investee’s management, if applicable, and the ability to participate in capital and operating decisions of the investee, including budgets, in the ordinary course of business. We invest in entities with varying structures, many of which do not have voting securities or interests, such as general partnerships, limited partnerships, and limited liability companies. In many of these structures, control of the entity rests with the general partners or managing members, while other members hold passive interests. The general partner or managing member may hold anywhere from a relatively small percentage of the total financial interests to a majority of the financial interests. For entities not deemed to be VIEs, where we serve as the sole general partner or managing member, we are considered to have the controlling financial interest and therefore the entity is consolidated, regardless of our financial interest percentage, unless there are other limited partners or investing members that can remove us as general partner without cause, dissolve the partnership without cause or effectively participate through substantive participative rights. In those circumstances where we, as majority controlling interest owner, can be removed without cause or cannot cause the entity to take actions that are significant in the ordinary course of business, because such actions could be vetoed by the minority controlling interest owner, we do not consolidate the entity. When we consolidate entities other than securitization VIEs, the third party ownership interests are reflected as non-controlling interests in consolidated subsidiaries, a separate component of equity, in our consolidated balance sheet. When we consolidate securitization VIEs, the third party ownership interests are reflected as VIE liabilities in our consolidated balance sheet because the beneficial interests payable to these third parties are legally issued in the form of debt. Our presentation of net income attributes earnings to controlling and non-controlling interests.
Variable Interest Entities	Variable Interest Entities In addition to the securitization VIEs, we have financed pools of our loans through collateralized loan obligations (“CLOs”) and a single asset securitization ("SASB"), which are considered VIEs. We also hold interests in certain other entities which are considered VIEs as the limited partners of those entities with equity at risk do not collectively possess (i) the right to remove the general partner or dissolve the partnership without cause or (ii) the right to participate in significant decisions made by the partnership. We evaluate all of our interests in VIEs for consolidation. When our interests are determined to be variable interests, we assess whether we are deemed to be the primary beneficiary of the VIE. The primary beneficiary of a VIE is required to consolidate the VIE. Accounting Standards Codification (“ASC”) 810, Consolidation, defines the primary beneficiary as the party that has both (i) the power to direct the activities of the VIE that most significantly impact its economic performance, and (ii) the obligation to absorb losses and the right to receive benefits from the VIE which could be potentially significant. We consider our variable interests as well as any variable interests of our related parties in making this determination. Where both of these factors are present, we are deemed to be the primary beneficiary and we consolidate the VIE. Where either one of these factors is not present, we are not the primary beneficiary and do not consolidate the VIE. To assess whether we have the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, we consider all facts and circumstances, including our role in establishing the VIE and our ongoing rights and responsibilities. This assessment includes: (i) identifying the activities that most significantly impact the VIE’s economic performance; and (ii) identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE or have the right to unilaterally remove those decision makers are deemed to have the power to direct the activities of a VIE. The right to remove the decision maker in a VIE must be exercisable without cause for the decision maker to not be deemed the party that has the power to direct the activities of a VIE. To assess whether we have the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, we consider all of our economic interests, including debt and equity investments, servicing fees and other arrangements deemed to be variable interests in the VIE. This assessment requires that we apply judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Factors considered in assessing significance include: the design of the VIE, including its capitalization structure; subordination of interests; payment priority; relative share of interests held across various classes within the VIE’s capital structure; and the reasons why the interests are held by us. Our purchased investment securities include unrated and non-investment grade rated securities issued by securitization trusts. In certain cases, we may contract to provide special servicing activities for these trusts, or, as holder of the controlling class, we may have the right to name and remove the special servicer for these trusts. In our role as special servicer, we provide services on defaulted loans within the trusts, such as foreclosure or work-out procedures, as permitted by the underlying contractual agreements. In exchange for these services, we receive a fee. These rights give us the ability to direct activities that could significantly impact the trust’s economic performance. However, in those instances where an unrelated third party has the right to unilaterally remove us as special servicer without cause, we do not have the power to direct activities that most significantly impact the trust’s economic performance. We evaluated all of our positions in such investments for consolidation. For securitization VIEs in which we are determined to be the primary beneficiary, all of the underlying assets, liabilities and equity of the structures are recorded on our books, and the initial investment, along with any associated unrealized holding gains and losses, are eliminated in consolidation. Similarly, the interest income earned from these structures, as well as the fees paid by these trusts to us in our capacity as special servicer, are eliminated in consolidation. Further, a portion of the identified servicing intangible asset associated with the servicing fee streams, and the corresponding amortization or change in fair value of the servicing intangible asset, are also eliminated in consolidation. We perform ongoing reassessments of: (i) whether any entities previously evaluated under the majority voting interest framework have become VIEs, based on certain events, and therefore subject to the VIE consolidation framework, and (ii) whether changes in the facts and circumstances regarding our involvement with a VIE causes our consolidation conclusion regarding the VIE to change. We elect the fair value option for initial and subsequent recognition of the assets and liabilities of our consolidated securitization VIEs. Interest income and interest expense associated with these VIEs are no longer relevant on a standalone basis because these amounts are already reflected in the fair value changes. We have elected to present these items in a single line on our consolidated statements of operations. The residual difference shown on our consolidated statements of operations in the line item “Change in net assets related to consolidated VIEs” represents our beneficial interest in the VIEs. We separately present the assets and liabilities of our consolidated securitization VIEs as individual line items on our consolidated balance sheets. The liabilities of our consolidated securitization VIEs consist solely of obligations to the bondholders of the related trusts, and are thus presented as a single line item entitled “VIE liabilities.” The assets of our consolidated securitization VIEs consist principally of loans, but at times, also include foreclosed loans which have been temporarily converted into real estate owned (“REO”). These assets in the aggregate are likewise presented as a single line item entitled “VIE assets.” Loans comprise the vast majority of our securitization VIE assets and are carried at fair value due to the election of the fair value option. When an asset becomes REO, it is due to non-performance of the loan. Because the loan is already at fair value, the carrying value of an REO asset is also initially at fair value. Furthermore, when we consolidate a trust, any existing REO would be consolidated at fair value. Once an asset becomes REO, its disposition time is relatively short. As a result, the carrying value of an REO generally approximates fair value under GAAP. In addition to sharing a similar measurement method as the loans in a trust, the securitization VIE assets as a whole can only be used to settle the obligations of the consolidated VIE. The assets of our securitization VIEs are not individually accessible by the bondholders, which creates inherent limitations from a valuation perspective. Also creating limitations from a valuation perspective is our role as special servicer, which provides us very limited visibility, if any, into the performing loans of a trust. REO assets generally represent a very small percentage of the overall asset pool of a trust. In new issue trusts there are no REO assets. We estimate that REO assets constitute approximately 1% of our consolidated securitization VIE assets, with the remaining 99% representing loans. However, it is important to note that the fair value of our securitization VIE assets is determined by reference to our securitization VIE liabilities as permitted under Accounting Standard Update ("ASU") 2014-13, Consolidation (Topic 810): Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity. In other words, our VIE liabilities are more reliably measurable than the VIE assets, resulting in our current measurement methodology which utilizes this value to determine the fair value of our securitization VIE assets as a whole. As a result, these percentages are not necessarily indicative of the relative fair values of each of these asset categories if the assets were to be valued individually. Due to our accounting policy election under ASU 2014-13, separately presenting two different asset categories would result in an arbitrary assignment of value to each, with one asset category representing a residual amount, as opposed to its fair value. However, as a pool, the fair value of the assets in total is equal to the fair value of the liabilities. For these reasons, the assets of our securitization VIEs are presented in the aggregate.
Fair Value Option	Fair Value Option The guidance in ASC 825, Financial Instruments, provides a fair value option election that allows entities to make an irrevocable election of fair value as the initial and subsequent measurement attribute for certain eligible financial assets and liabilities. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings. The decision to elect the fair value option is determined on an instrument by instrument basis and must be applied to an entire instrument and is irrevocable once elected. Assets and liabilities measured at fair value pursuant to this guidance are required to be reported separately in our consolidated balance sheets from those instruments using another accounting method. We have elected the fair value option for certain eligible financial assets and liabilities of our consolidated securitization VIEs, residential loans held-for-investment, loans held-for-sale originated or acquired for future securitization and purchased CMBS issued by VIEs we could consolidate in the future. The fair value elections for VIE and securitization related items were made in order to mitigate accounting mismatches between the carrying value of the instruments and the related assets and liabilities that we consolidate at fair value. The fair value elections for residential loans held-for-investment were made in order to maintain consistency across all our residential loans. The fair value elections for mortgage loans held-for-sale were made due to the expected short-term holding period of these instruments.
Fair Value Measurements	Fair Value Measurements We measure our mortgage-backed securities, investments of consolidated affordable housing fund, derivative assets and liabilities, domestic servicing rights intangible asset and any assets or liabilities where we have elected the fair value option at fair value. When actively quoted observable prices are not available, we either use implied pricing from similar assets and liabilities or valuation models based on net present values of estimated future cash flows, adjusted as appropriate for liquidity, credit, market and/or other risk factors. As discussed above, we measure the assets and liabilities of consolidated securitization VIEs at fair value pursuant to our election of the fair value option. The securitization VIEs in which we invest are “static”; that is, no reinvestment is permitted, and there is no active management of the underlying assets. In determining the fair value of the assets and liabilities of the securitization VIEs, we maximize the use of observable inputs over unobservable inputs. Refer to Note 21 for further discussion regarding our fair value measurements. Valuation Process We have valuation control processes in place to validate the fair value of the Company’s financial assets and liabilities measured at fair value including those derived from pricing models. These control processes are designed to assure that the values used for financial reporting are based on observable inputs wherever possible. In the event that observable inputs are not available, the control processes are designed to assure that the valuation approach utilized is appropriate and consistently applied and the assumptions are reasonable. Pricing Verification—We use recently executed transactions, other observable market data such as exchange data, broker/dealer quotes, third party pricing vendors and aggregation services for validating the fair values generated using valuation models. Pricing data provided by approved external sources is evaluated using a number of approaches; for example, by corroborating the external sources’ prices to executed trades, analyzing the methodology and assumptions used by the external source to generate a price and/or by evaluating how active the third party pricing source (or originating sources used by the third party pricing source) is in the market. Unobservable Inputs—Where inputs are not observable, we review the appropriateness of the proposed valuation methodology to ensure it is consistent with how a market participant would arrive at the unobservable input. The valuation methodologies utilized in the absence of observable inputs may include extrapolation techniques and the use of comparable observable inputs. Any changes to the valuation methodology will be reviewed by our management to ensure the changes are appropriate. The methods used may produce a fair value calculation that is not indicative of net realizable value or reflective of future fair values. Furthermore, while we anticipate that our valuation methods are appropriate and consistent with other market participants, the use of different methodologies, or assumptions, to determine the fair value could result in a different estimate of fair value at the reporting date. Fair Value on a Recurring Basis We determine the fair value of our financial assets and liabilities measured at fair value on a recurring basis as follows: Loans held-for-sale, commercial We measure the fair value of our commercial mortgage loans held-for-sale using a discounted cash flow analysis unless observable market data (i.e., securitized pricing) is available. A discounted cash flow analysis requires management to make estimates regarding future interest rates and credit spreads. The most significant of these inputs relates to credit spreads and is unobservable. Thus, we have determined that the fair values of mortgage loans valued using a discounted cash flow analysis should be classified in Level III of the fair value hierarchy, while mortgage loans valued using securitized pricing should be classified in Level II of the fair value hierarchy. Mortgage loans classified in Level III are transferred to Level II if securitized pricing becomes available. Loans held-for-sale and loans held-for-investment, residential We measure the fair value of our residential loans held-for-sale and held-for-investment based on the net present value of expected future cash flows using a combination of observable and unobservable inputs. Observable market participant assumptions include pricing related to trades of residential loans with similar characteristics. Unobservable inputs include the expectation of future cash flows, which involves judgments about the underlying collateral, the creditworthiness of the borrower, estimated prepayment speeds, estimated future credit losses, forward interest rates, investor yield requirements and certain other factors. At each measurement date, we consider both the observable and unobservable valuation inputs in the determination of fair value. However, given the significance of the unobservable inputs, these loans have been classified within Level III. RMBS RMBS are valued utilizing observable and unobservable market inputs. The observable market inputs include recent transactions, broker quotes and vendor prices (“market data”). However, given the implied price dispersion amongst the market data, the fair value determination for RMBS has also utilized significant unobservable inputs in discounted cash flow models including prepayments, default and severity estimates based on the recent performance of the collateral, the underlying collateral characteristics, industry trends, as well as expectations of macroeconomic events (e.g., housing price curves, interest rate curves, etc.). At each measurement date, we consider both the observable and unobservable valuation inputs in the determination of fair value. However, given the significance of the unobservable inputs these securities have been classified within Level III. CMBS CMBS are valued utilizing both observable and unobservable market inputs. These factors include projected future cash flows, ratings, subordination levels, vintage, remaining lives, credit issues, recent trades of similar securities and the spreads used in the prior valuation. We obtain current market spread information where available and use this information in evaluating and validating the market price of all CMBS. Depending upon the significance of the fair value inputs used in determining these fair values, these securities are classified in either Level II or Level III of the fair value hierarchy. CMBS may shift between Level II and Level III of the fair value hierarchy if the significant fair value inputs used to price the CMBS become or cease to be observable. Equity security The equity security is publicly registered and traded in the U.S. and its market price is listed on the London Stock Exchange. The security has been classified within Level I. Woodstar Fund Investments The fair value of investments held by the Woodstar Fund is determined based on observable and unobservable market inputs. The initial fair value of the Woodstar Fund's investments at its November 5, 2021 establishment date was determined by reference to the purchase price paid by third party investors, which was consistent with both a recent external appraisal as well as our extensive marketing efforts to sell interests in the Woodstar Fund, plus working capital. For the properties, the third party appraisal applied the income capitalization approach with corroborative support from the sales comparison approach. The cost approach is not employed, as it is typically not emphasized by potential investors in the multifamily affordable housing sector. The income capitalization approach estimates an income stream for a property over a 10-year period and discounts this income plus a reversion (presumed sale) into a present value at a risk adjusted discount rate. Terminal capitalization rates and discount rates utilized in this approach are derived from market transactions as well as other financial and industry data. For secured financing, the third party appraisal discounted the contractual cash flows at the interest rate at which such arrangements would bear if executed in the current market. The fair value of investment level working capital is assumed to approximate carrying value due to its primarily short-term monetary nature. The fair value of interest rate derivatives is determined using the methodology described in the Derivatives discussion below. Given the significance of the unobservable inputs used in the respective valuations, the Woodstar Fund’s investments have been classified within Level III of the fair value hierarchy. Domestic servicing rights The fair value of this intangible is determined using discounted cash flow modeling techniques which require management to make estimates regarding future net servicing cash flows, including forecasted loan defeasance, control migration, delinquency and anticipated maturity defaults which are calculated assuming a debt yield at which default occurs. Since the most significant of these inputs are unobservable, we have determined that the fair values of this intangible in its entirety should be classified in Level III of the fair value hierarchy. Derivatives The valuation of derivative contracts are determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market based inputs, including interest rate curves, spot and market forward points and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. We incorporate credit valuation adjustments to appropriately reflect both our own non-performance risk and the respective counterparty’s non-performance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of non-performance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. The valuation of over the counter derivatives are determined using discounted cash flows based on Overnight Index Swap (“OIS”) rates. Fully collateralized trades are discounted using OIS with no additional economic adjustments to arrive at fair value. Uncollateralized or partially collateralized trades are also discounted at OIS, but include appropriate economic adjustments for funding costs (i.e., a LIBOR OIS basis adjustment to approximate uncollateralized cost of funds) and credit risk. For credit index instruments, fair value is determined based on changes in the relevant indices from the date of initiation of the instrument to the reporting date, as these changes determine the amount of any future cash settlement between us and the counterparty. These indices are considered Level II inputs as they are directly observable. Although we have determined that the majority of the inputs used to value our derivatives fall within Level II of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level III inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. However, as of December 31, 2021 and 2020, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined that our derivative valuations in their entirety are classified in Level II of the fair value hierarchy. Liabilities of consolidated VIEs Our consolidated VIE liabilities generally represent bonds that are not owned by us. The majority of these are either traded in the marketplace or can be analogized to similar securities that are traded in the marketplace. For these liabilities, pricing is considered to be Level II, where the valuation is based upon quoted prices for similar instruments traded in active markets. We generally utilize third party pricing service providers for valuing these liabilities. In order to determine whether to utilize the valuations provided by third parties, we conduct an ongoing evaluation of their valuation methodologies and processes, as well as a review of the individual valuations themselves. In evaluating third party pricing for reasonableness, we consider a variety of factors, including market transaction information for the particular bond, market transaction information for bonds within the same trust, market transaction information for similar bonds, the bond’s ratings and the bond’s subordination levels. For the minority portion of our consolidated VIE liabilities which consist of unrated or non-investment grade bonds that are not owned by us, pricing may be either Level II or Level III. If independent third party pricing similar to that noted above is available, we consider the valuation to be Level II. If such third party pricing is not available, the valuation is generated from model-based techniques that use significant unobservable assumptions, and we consider the valuation to be Level III. For VIE liabilities classified as Level III, valuation is determined based on discounted expected future cash flows which take into consideration expected duration and yields based on market transaction information, ratings, subordination levels, vintage and current market spread. VIE liabilities may shift between Level II and Level III of the fair value hierarchy if the significant fair value inputs used to price the VIE liabilities become or cease to be observable. Assets of consolidated VIEs The securitization VIEs in which we invest are “static”; that is, no reinvestment is permitted, and there is no active management of the underlying assets. In determining the fair value of the assets of the VIE, we maximize the use of observable inputs over unobservable inputs. The individual assets of a VIE are inherently incapable of precise measurement given their illiquid nature and the limitations on available information related to these assets. Because our methodology for valuing these assets does not value the individual assets of a VIE, but rather uses the value of the VIE liabilities as an indicator of the fair value of VIE assets as a whole, we have determined that our valuations of VIE assets in their entirety should be classified in Level III of the fair value hierarchy. Fair Value Only Disclosed We determine the fair value of our financial instruments and assets where fair value is disclosed as follows: Loans held-for-investment and loans held-for-sale We estimate the fair values of our loans not carried at fair value on a recurring basis by discounting their expected cash flows at a rate we estimate would be demanded by the market participants that are most likely to buy our loans. The expected cash flows used are generally the same as those used to calculate our level yield income in the financial statements. Since these inputs are unobservable, we have determined that the fair value of these loans in their entirety would be classified in Level III of the fair value hierarchy. HTM debt securities We estimate the fair value of our mandatorily redeemable preferred equity interests in commercial real estate companies and infrastructure bonds using the same methodology described for our loans held-for-investment. We estimate the fair value of our HTM CMBS using the same methodology described for our CMBS carried at fair value on a recurring basis. Secured financing agreements, CLOs and SASB The fair value of the secured financing agreements, CLOs and SASB are determined by discounting the contractual cash flows at the interest rate we estimate such arrangements would bear if executed in the current market. We have determined that our valuation of these instruments should be classified in Level III of the fair value hierarchy. Unsecured senior notes The fair value of our unsecured senior notes is determined based on the last available bid price for the respective notes in the current market. As these prices represent observable market data, we have determined that the fair value of these instruments would be classified in Level II of the fair value hierarchy.
Business Combinations	Business Combinations Under ASC 805, Business Combinations, the acquirer in a business combination must recognize, with certain exceptions, the fair values of assets acquired, liabilities assumed, and non-controlling interests when the acquisition constitutes a change in control of the acquired entity. As goodwill is calculated as a residual, all goodwill of the acquired business, not just the acquirer’s share, is recognized under this “full goodwill” approach. During the measurement period, a period which shall not exceed one year, we prospectively adjust the provisional amounts recognized to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized. We apply the asset acquisition provisions of ASC 805 in accounting for acquisitions of real estate with in-place leases where substantially all of the fair value of the assets acquired is concentrated in either a single identifiable asset or group of similar identifiable assets. This results in the acquired properties being recognized initially at their purchase price inclusive of acquisition costs, which are capitalized. All other acquisitions of real estate with in-place leases are accounted for in accordance with the business combination provisions of ASC 805. We also apply the asset acquisition provisions of ASC 805 for acquired real estate assets where a lease is entered into concurrently with the acquisition of the asset, such as in sale leaseback transactions.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash in banks and short‑term investments. Short‑term investments are comprised of highly liquid instruments with original maturities of three months or less. The Company maintains its cash and cash equivalents in multiple financial institutions and at times these balances exceed federally insurable limits.
Restricted Cash	Restricted CashRestricted cash includes cash and cash equivalents that are legally or contractually restricted as to withdrawal or usage and primarily includes (i) cash collateral associated with derivative financial instruments, (ii) loan payments received by our Infrastructure Lending Segment which are restricted by our lender and periodically applied, in part, to the outstanding balance of the Infrastructure Lending debt facility and (iii) funds held on behalf of borrowers and tenants.
Loans Held-for-Investment	Loans Held-for-Investment Loans that are held for investment (“HFI”) are carried at cost, net of unamortized acquisition premiums or discounts, loan fees and origination costs, as applicable, and net of credit loss allowances as discussed below, unless we have elected to apply the fair value option at purchase.
Loans Held-For-Sale	Loans Held-For-Sale Our loans that we intend to sell or liquidate in the short-term are classified as held-for-sale and are carried at the lower of amortized cost or fair value, unless we have elected to apply the fair value option at origination or purchase. We periodically enter into derivative financial instruments to hedge unpredictable changes in fair value of loans held-for-sale, including changes resulting from both interest rates and credit quality. Because these derivatives are not designated, changes in their fair value are recorded in earnings. In order to best reflect the results of the hedged loan portfolio in earnings, we have elected the fair value option for these loans. As a result, changes in the fair value of the loans are also recorded in earnings.
Investment Securities	Investment Securities We designate our debt investment securities as held-to-maturity (“HTM”), available-for-sale (“AFS”), or trading depending on our investment strategy and ability to hold such securities to maturity. HTM debt securities where we have not elected to apply the fair value option are stated at cost plus any premiums or discounts, which are amortized or accreted through the consolidated statements of operations using the effective interest method. Debt securities we (i) do not hold for the purpose of selling in the near-term, or (ii) may dispose of prior to maturity, are classified as AFS and are carried at fair value in the accompanying financial statements. Unrealized gains or losses on AFS debt securities where we have not elected the fair value option are reported as a component of accumulated other comprehensive income (“AOCI”) in stockholders’ equity. Our HTM and AFS debt securities are also subject to credit loss allowances as discussed below. Our only equity investment security is carried at fair value, with unrealized holding gains and losses recorded in earnings.
Credit Losses	Credit Losses Loans and Debt Securities Measured at Amortized Cost ASC 326, Financial Instruments – Credit Losses, became effective for the Company on January 1, 2020. ASC 326 mandates the use of a current expected credit loss model (“CECL”) for estimating future credit losses of certain financial instruments measured at amortized cost, instead of the “incurred loss” credit model previously required under GAAP. The CECL model requires the consideration of possible credit losses over the life of an instrument as opposed to only estimating credit losses upon the occurrence of a discrete loss event under the previous “incurred loss” methodology. The CECL model applies to our HFI loans and our HTM debt securities which are carried at amortized cost, including future funding commitments and accrued interest receivable related to those loans and securities. However, as permitted by ASC 326, we have elected not to measure an allowance for credit losses on accrued interest receivable (which is classified separately on our consolidated balance sheet), but rather write off in a timely manner by reversing interest income and/or cease accruing interest that would likely be uncollectible. Our adoption of the CECL model resulted in a $32.3 million increase to our total allowance for credit losses, which was recognized as a cumulative-effect adjustment to accumulated deficit as of January 1, 2020. As we do not have a history of realized credit losses on our HFI loans and HTM securities, we have subscribed to third party database services to provide us with historical industry losses for both commercial real estate and infrastructure loans. Using these losses as a benchmark, we determine expected credit losses for our loans and securities on a collective basis within our commercial real estate and infrastructure portfolios. See Note 5 for further discussion of our methodologies. We also evaluate each loan and security measured at amortized cost for credit deterioration at least quarterly. Credit deterioration occurs when it is deemed probable that we will not be able to collect all amounts due according to the contractual terms of the loan or security. If a loan or security is considered to be credit deteriorated, we depart from the industry loss rate approach described above and determine the credit loss allowance as any excess of the amortized cost basis of the loan or security over (i) the present value of expected future cash flows discounted at the contractual effective interest rate or (ii) the fair value of the collateral, if repayment is expected solely from the collateral. Available-for-Sale Debt Securities Separate provisions of ASC 326 apply to our AFS debt securities, which are carried at fair value with unrealized gains and losses reported as a component of AOCI. We are required to establish an initial credit loss allowance for those securities that are purchased with credit deterioration (“PCD”) by grossing up the amortized cost basis of each security and providing an offsetting credit loss allowance for the difference between expected cash flows and contractual cash flows, both on a present value basis. As of the January 1, 2020 effective date, no such credit loss allowance gross-up was required on our AFS debt securities with PCD due to their individual unrealized gain positions as of that date. Subsequently, cumulative adverse changes in expected cash flows on our AFS debt securities are recognized currently as an increase to the allowance for credit losses. However, the allowance is limited to the amount by which the AFS debt security’s amortized cost exceeds its fair value. Favorable changes in expected cash flows are first recognized as a decrease to the allowance for credit losses (recognized currently in earnings). Such changes would be recognized as a prospective yield adjustment only when the allowance for credit losses is reduced to zero. A change in expected cash flows that is attributable solely to a change in a variable interest reference rate does not result in a credit loss and is accounted for as a prospective yield adjustment.
Properties Held-For-Investment	Properties Held-For-Investment Properties, net, as reported on our consolidated balance sheets, consist of commercial real estate properties held-for-investment and are recorded at cost, less accumulated depreciation and impairments, if any. Properties consist primarily of land, buildings and improvements. Land is not depreciated, and buildings and improvements are depreciated on a straight-line basis over their estimated useful lives. Ordinary repairs and maintenance are expensed as incurred; major replacements and betterments are capitalized and depreciated on a straight-line basis over their estimated useful lives. We review properties for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability is determined by comparing the carrying amount of the property to the undiscounted future net cash flows it is expected to generate. If such carrying amount exceeds the expected undiscounted future net cash flows, we adjust the carrying amount of the property to its estimated fair value.
Properties Held-For-Sale	Properties Held-For-SaleProperties and any associated intangible assets are presented within properties held-for-sale on our consolidated balance sheet when the sale of the property is considered probable, at which time we cease depreciation and amortization of the property and the associated intangibles. Held-for-sale properties are reported at the lower of their carrying value or fair value less costs to sell.
Investments in Unconsolidated Entities	Investments in Unconsolidated Entities We own non‑controlling equity interests in various privately‑held partnerships and limited liability companies. Unless we elect the fair value option under ASC 825, we use the fair value practicability election described below to account for investments in which our interest is so minor that we have virtually no influence over the underlying investees. We use the equity method to account for all other non‑controlling interests in partnerships and limited liability companies. Equity method investments are initially recorded at cost and subsequently adjusted for our share of income or loss, as well as contributions made or distributions received. Our other equity investments set forth in Note 9 do not have readily determinable fair values. Therefore, we have elected the fair value practicability exception under ASC 321, Equity Securities, whereby we measure those investments within its scope at cost, less any impairment, plus or minus observable price changes from orderly transactions of identical or similar investments of the same issuer. Our former investment in Federal Home Loan Bank (“FHLB”) stock, which is not within the scope of ASC 321, was carried at cost less any impairment. We review our equity method and other investments not subject to the fair value practicability election for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. For our investments under the fair value practicability election, we perform a qualitative assessment to identify impairment at the end of each reporting period. An impairment loss is measured based on the excess of the carrying amount of an investment over its estimated fair value. Impairment analyses are based on current plans, intended holding periods, estimated fair values of underlying assets and available information at the time the analyses are prepared.
Goodwill	Goodwill Goodwill is not amortized, but rather tested for impairment annually or more frequently if events or changes in circumstances indicate potential impairment. Goodwill at December 31, 2021 represents the excess of the consideration paid over the fair value of net assets acquired in connection with the acquisitions of LNR Property LLC (“LNR”) in April 2013 and the Infrastructure Lending Segment in September 2018 and October 2018. In testing goodwill for impairment, we follow ASC 350, Intangibles—Goodwill and Other, which permits a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit is less than its carrying value including goodwill. If the qualitative assessment determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying value including goodwill, then no impairment is determined to exist for the reporting unit. However, if the qualitative assessment determines that it is more likely than not that the fair value of the reporting unit is less than its carrying value including goodwill, or we choose not to perform the qualitative assessment, then we compare the fair value of that reporting unit with its carrying value, including goodwill. ASU 2017-04, Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment, became effective for the Company on January 1, 2020. This ASU specifies that if the carrying value of a reporting unit exceeds its fair value, goodwill is considered impaired with the impairment loss measured as the excess of the reporting unit’s carrying value (inclusive of goodwill) over its fair value, eliminating the requirement that all assets and liabilities of the reporting unit be remeasured individually in connection with measurement of goodwill impairment.
Servicing Rights Intangibles	Servicing Rights IntangiblesOur identifiable intangible assets include domestic special servicing rights for which we have elected to apply the fair value measurement method, which is necessary to conform to our election of the fair value option for measuring the assets and liabilities of the securitization VIEs consolidated pursuant to ASC 810.
Lease Intangibles	Lease IntangiblesIn connection with our acquisition of properties, we recognize intangible lease assets and liabilities associated with certain noncancelable operating leases of the acquired properties. These intangible lease assets and liabilities include in-place lease intangible assets, favorable lease intangible assets and unfavorable lease liabilities. In-place lease intangible assets reflect the acquired benefit of purchasing properties with in-place leases and are measured based on estimates of direct costs associated with leasing the property and lost rental income during projected lease-up and free rent periods, both of which are avoided due to the presence of in-place leases at the acquisition date. Favorable and unfavorable lease intangible assets and liabilities reflect the terms of in-place tenant leases being either favorable or unfavorable relative to market terms at the acquisition date. The estimated fair values of our favorable and unfavorable lease assets and liabilities at the respective acquisition dates represent the discounted cash flow differential between the contractual cash flows of such leases and the estimated cash flows that comparable leases at market terms would generate. Our intangible lease assets and liabilities are recognized within intangible assets and other liabilities, respectively, in our consolidated balance sheets. Our in-place lease intangible assets are amortized to amortization expense while our favorable and unfavorable lease intangible assets and liabilities where we are the lessor are amortized to rental income. Both our favorable and unfavorable lease intangible assets and liabilities are amortized over the remaining noncancelable term of the respective leases on a straight-line basis.
Leases	Leases On January 1, 2019, ASC 842, Leases, became effective for the Company. ASC 842 establishes a right-of-use model for lessee accounting which results in the recognition of most leased assets and lease liabilities on the balance sheet of the lessee. Lessor accounting was not significantly affected by this ASC. We elected to apply the provisions of ASC 842 as of January 1, 2019 and not to retrospectively adjust prior periods presented. Such application did not result in any cumulative-effect adjustment as of January 1, 2019. We elected the “package of practical expedients” for transition purposes, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs for leases that commenced prior to January 1, 2019. We also elected not to apply the recognition provisions of ASC 842 to short-term leases, which have original lease terms of 12 months or less. As a lessor, we elected not to separate nonlease components, such as reimbursements from tenants for common area maintenance (“CAM”), from lease components for all classes of underlying assets, and continue to recognize such nonlease components ratably in rental income. We also elected to continue to exclude from rental income all sales, use and other similar taxes collected from lessees. As required by ASC 842, we no longer record as revenues and expenses lessor costs (such as property taxes) paid directly by the lessees. The application of ASC 842 has had no material effect on our consolidated financial statements, as all of our leases, as both lessor and lessee, are currently classified as operating leases, which are subject to essentially the same straight-line revenue and expense recognition as in the past.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities We record all derivatives on our consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on whether we have elected to designate a derivative in a hedging relationship and have satisfied the criteria necessary to apply hedge accounting under GAAP. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. We regularly enter into derivative contracts that are intended to economically hedge certain of our risks, even though the transactions may not qualify for, or we may not elect to pursue, hedge accounting. In such cases, changes in the fair value of the derivatives are recorded in earnings. Generally, our derivatives are subject to master netting arrangements, though we elect to present all derivative assets and liabilities on a gross basis within our consolidated balance sheets.
Convertible Senior Notes	Convertible Senior Notes Effective January 1, 2021, the Company early adopted 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), which removes certain separation models for convertible debt instruments and convertible preferred stock that require the separation into a debt component and an equity or derivative component. Consequently, our convertible senior notes (the “Convertible Notes”), which were previously accounted for as having separate liability and equity components, are now accounted for as a single liability measured at amortized cost. The standard was adopted using the modified retrospective method of transition, which resulted in a cumulative decrease to additional paid-in capital of $3.7 million, partially offset by a cumulative decrease to accumulated deficit of $2.2 million as of January 1, 2021.
Revenue Recognition	Revenue Recognition Interest Income Interest income on performing loans and financial instruments is accrued based on the outstanding principal amount and contractual terms of the instrument. For loans where we do not elect the fair value option, origination fees and direct loan origination costs are also recognized in interest income over the loan term as a yield adjustment using the effective interest method. When we elect the fair value option, origination fees and direct loan costs are recorded directly in income and are not deferred. Discounts or premiums associated with the purchase of non-performing loans and investment securities are amortized or accreted into interest income as a yield adjustment on the effective interest method, based on expected cash flows through the expected maturity date of the investment. On at least a quarterly basis, we review and, if appropriate, make adjustments to our cash flow projections. We cease accruing interest on non-performing loans at the earlier of (i) the loan becoming significantly past due or (ii) management concluding that a full recovery of all interest and principal is doubtful. Interest income on non-accrual loans in which management expects a full recovery of the loan’s outstanding principal balance is only recognized when received in cash. If a full recovery of principal is doubtful, the cost recovery method is applied whereby any cash received is applied to the outstanding principal balance of the loan. A non-accrual loan is returned to accrual status at such time as the loan becomes contractually current and management believes all future principal and interest will be received according to the contractual loan terms. For loans acquired with deteriorated credit quality, interest income is only recognized to the extent that our estimate of undiscounted expected principal and interest exceeds our investment in the loan. Such excess, if any, is recognized as interest income on a level-yield basis over the life of the loan. Upon the sale of loans or securities which are not accounted for pursuant to the fair value option, the excess (or deficiency) of net proceeds over the net carrying value of such loans or securities is recognized as a realized gain (loss). Servicing Fees We typically seek to be the special servicer on CMBS transactions in which we invest. When we are appointed to serve in this capacity, we earn special servicing fees from the related activities performed, which consist primarily of overseeing the workout of under-performing and non-performing loans underlying the CMBS transactions. These fees are recognized in income in the period in which the services are performed and the revenue recognition criteria have been met. Rental Income Rental income is recognized when earned from tenants. For leases that provide rent concessions or fixed escalations over the lease term, rental income is recognized on a straight-line basis over the noncancelable term of the lease. In net lease arrangements, costs reimbursable from tenants are recognized in rental income in the period in which the related expenses are incurred as we are generally the primary obligor with respect to purchasing goods and services for property operations. In instances where the tenant is responsible for property maintenance and repairs and contracts and settles such costs directly with third party service providers, we do not reflect those expenses in our consolidated statement of operations as the tenant is the primary obligor.
Securitizations, Sales and Financing Arrangements	Securitizations, Sales and Financing Arrangements We periodically sell our financial assets, such as commercial mortgage loans, residential loans, CMBS, RMBS and other assets. In connection with these transactions, we may retain or acquire senior or subordinated interests in the related assets. Gains and losses on such transactions are recognized in accordance with ASC 860, Transfers and Servicing, which is based on a financial components approach that focuses on control. Under this approach, after a transfer of financial assets that meets the criteria for treatment as a sale—legal isolation, ability of transferee to pledge or exchange the transferred assets without constraint, and transferred control—an entity recognizes the financial assets it retains and any liabilities it has incurred, derecognizes the financial assets it has sold, and derecognizes liabilities when extinguished. We determine the gain or loss on sale of the assets by allocating the carrying value of the sold asset between the sold asset and the interests retained based on their relative fair values, as applicable. The gain or loss on sale is the difference between the cash proceeds from the sale and the amount allocated to the sold asset. If the sold asset is being accounted for pursuant to the fair value option, there is no gain or loss.
Deferred Financing Costs	Deferred Financing Costs Costs incurred in connection with debt issuance are capitalized and amortized to interest expense over the terms of the respective debt agreements. Such costs are presented as a direct deduction from the carrying value of the related debt liability.
Acquisition and Investment Pursuit Costs	Acquisition and Investment Pursuit Costs Costs incurred in connection with acquisitions of investments, loans and businesses, as well as in pursuing unsuccessful acquisitions and investments, are recorded within acquisition and investment pursuit costs in our consolidated statements of operations when incurred. Costs incurred in connection with acquisitions of real estate not accounted for as business combinations are capitalized within the purchase price. These costs reflect services performed by third parties and principally include due diligence and legal services.
Share-Based Payments	Share‑Based PaymentsThe fair value of the restricted stock (“RSAs”) or restricted stock units (“RSUs”) granted is recorded as expense on a straight‑line basis over the vesting period for the award, with an offsetting increase in stockholders’ equity. The fair value is determined based upon the stock price on the grant date.
Foreign Currency Translation	Foreign Currency Translation Our assets and liabilities denominated in foreign currencies are translated into U.S. dollars using foreign currency exchange rates at the end of the reporting period. Income and expenses are translated at the average exchange rates for each reporting period. The effects of translating the assets, liabilities and income of our foreign investments held by entities with a U.S. dollar functional currency are included in foreign currency gain (loss) in the consolidated statements of operations or other comprehensive income (“OCI”) for debt securities available-for-sale for which the fair value option has not been elected. The effects of translating the assets, liabilities and income of our foreign investments held by entities with functional currencies other than the U.S. dollar are included in OCI. Realized foreign currency gains and losses and changes in the value of foreign currency denominated monetary assets and liabilities are included in the determination of net income and are reported as foreign currency gain (loss) in our consolidated statements of operations.
Income Taxes	Income Taxes The Company has elected to be taxed as a REIT under the Code. The Company is subject to federal income taxation at corporate rates on its REIT taxable income, however, the Company is allowed a deduction for the amount of dividends paid to its stockholders in arriving at its REIT taxable income. As a result, distributed net income of the Company is subjected to taxation at the stockholder level only. The Company intends to continue operating in a manner that will permit it to maintain its qualification as a REIT for tax purposes. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company evaluates the realizability of its deferred tax assets and recognizes a valuation allowance if, based on the available evidence, both positive and negative, it is more likely than not that some portion or all of its deferred tax assets will not be realized. When evaluating the realizability of its deferred tax assets, the Company considers, among other matters, estimates of expected future taxable income, nature of current and cumulative losses, existing and projected book/tax differences, tax planning strategies available, and the general and industry specific economic outlook. This realizability analysis is inherently subjective, as it requires the Company to forecast its business and general economic environment in future periods. We recognize tax positions in the financial statements only when it is more likely than not that, based on the technical merits of the tax position, the position will be sustained upon examination by the relevant taxing authority. A tax position is measured at the largest amount of benefit that will more likely than not be realized upon settlement. If, as a result of new events or information, a recognized tax position no longer is considered more likely than not to be sustained upon examination, a liability is established for the unrecognized benefit with a corresponding charge to income tax expense in our consolidated statement of operations. We report interest and penalties, if any, related to income tax matters as a component of income tax expense.
Earnings Per Share	Earnings Per Share We present both basic and diluted earnings per share (“EPS”) amounts in our financial statements. Basic EPS excludes dilution and is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Diluted EPS reflects the maximum potential dilution that could occur from (i) our share-based compensation, consisting of unvested RSAs and RSUs, (ii) shares contingently issuable to our Manager, (iii) the conversion options associated with our Convertible Notes (see Notes 12 and 19) and (iv) non-controlling interests that are redeemable with our common stock (see Note 18). Potential dilutive shares are excluded from the calculation if they have an anti-dilutive effect in the period. Nearly all of the Company’s unvested RSUs and RSAs contain rights to receive non-forfeitable dividends and thus are participating securities. In addition, the non-controlling interests that are redeemable with our common stock are considered participating securities because they earn a preferred return indexed to the dividend rate on our common stock (see Note 18). Due to the existence of these participating securities, the two-class method of computing EPS is required, unless another method is determined to be more dilutive. Under the two-class method, undistributed earnings are reallocated between shares of common stock and participating securities. For the years ended December 31, 2021, 2020 and 2019, the two-class method resulted in the most dilutive EPS calculation.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash investments, CMBS, RMBS, loan investments and interest receivable. We may place cash investments in excess of insured amounts with high quality financial institutions. We perform an ongoing analysis of credit risk concentrations in our investment portfolio by evaluating exposure to various counterparties, markets, underlying property types, contract terms, tenant mix and other credit metrics.
Use of Estimates	Use of Estimates The preparation of 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 at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. The most significant and subjective estimate that we make is the projection of cash flows we expect to receive on our investments, which has a significant impact on the amount of income that we record and/or disclose. In addition, the fair value of assets and liabilities that are estimated using a discounted cash flows method is significantly impacted by the rates at which we estimate market participants would discount the expected cash flows. We believe the estimates and assumptions underlying our consolidated financial statements are reasonable and supportable based on the information available as of December 31, 2021. However, uncertainty over the ultimate impact the COVID-19 pandemic, including variants and resurgences, will have on the global economy generally, and our business in particular, makes any estimates and assumptions as of December 31, 2021 inherently less certain than they would be absent the current and potential impacts of COVID-19. Actual results may ultimately differ from those estimates.
Recent Accounting Developments	Recent Accounting Developments On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and on January 11, 2021, issued ASU 2021-01, Reference Rate Reform (Topic 848) – Scope, both of which provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or other reference rates expected to be discontinued because of reference rate reform. These ASUs are effective through December 31, 2022. The Company has not adopted any of the optional expedients or exceptions through December 31, 2021, but will continue to evaluate the possible adoption of any such expedients or exceptions during the effective period as circumstances evolve.

Balance Sheet Presentation of Securitization Variable Interest Entities

We operate investment businesses that acquire unrated, investment grade and non-investment grade rated CMBS and RMBS. These securities represent interests in securitization structures (commonly referred to as special purpose entities, or “SPEs”). These SPEs are structured as pass through entities that receive principal and interest on the underlying collateral and distribute those payments to the certificate holders. Under accounting principles generally accepted in the United States of America (“GAAP”), SPEs typically qualify as VIEs. These are entities that, by design, either (1) lack sufficient equity to permit the entity to finance its activities without additional subordinated financial support from other parties, or (2) have equity investors that do not have the ability to make significant decisions relating to the entity’s operations through voting rights, or do not have the obligation to absorb the expected losses, or do not have the right to receive the residual returns of the entity.

Because we often serve as the special servicer or servicing administrator of the trusts in which we invest, or we have the ability to remove and replace the special servicer without cause, consolidation of these structures is required pursuant to GAAP as outlined in detail below. This results in a consolidated balance sheet which presents the gross assets and liabilities of the VIEs. The assets and other instruments held by these VIEs are restricted and can only be used to fulfill the obligations of the entity. Additionally, the obligations of the VIEs do not have any recourse to the general credit of any other consolidated entities, nor to us as the consolidator of these VIEs.

The VIE liabilities initially represent investment securities on our balance sheet (pre-consolidation). Upon consolidation of these VIEs, our associated investment securities are eliminated, as is the interest income related to those securities. Similarly, the fees we earn in our roles as special servicer of the bonds issued by the consolidated VIEs or as collateral administrator of the consolidated VIEs are also eliminated. Finally, a portion of the identified servicing intangible associated with the eliminated fee streams is eliminated in consolidation.

Basis of Accounting and Principles of Consolidation

The accompanying consolidated financial statements include our accounts and those of our consolidated subsidiaries and VIEs. Intercompany amounts have been eliminated in consolidation.

Entities not deemed to be VIEs are consolidated if we own a majority of the voting securities or interests or hold the general partnership interest, except in those instances in which the minority voting interest owner or limited partner can remove us as general partner without cause, dissolve the partnership without cause or effectively participate through substantive participative rights. Substantive participative rights include the ability to select, terminate and set compensation of the investee’s management, if applicable, and the ability to participate in capital and operating decisions of the investee, including budgets, in the ordinary course of business.

We invest in entities with varying structures, many of which do not have voting securities or interests, such as general partnerships, limited partnerships, and limited liability companies. In many of these structures, control of the entity rests with the general partners or managing members, while other members hold passive interests. The general partner or managing member may hold anywhere from a relatively small percentage of the total financial interests to a majority of the financial interests. For entities not deemed to be VIEs, where we serve as the sole general partner or managing member, we are considered to have the controlling financial interest and therefore the entity is consolidated, regardless of our financial interest percentage, unless there are other limited partners or investing members that can remove us as general partner without cause, dissolve the partnership without cause or effectively participate through substantive participative rights. In those circumstances where we, as majority controlling interest owner, can be removed without cause or cannot cause the entity to take actions that are significant in the ordinary course of business, because such actions could be vetoed by the minority controlling interest owner, we do not consolidate the entity.

When we consolidate entities other than securitization VIEs, the third party ownership interests are reflected as non-controlling interests in consolidated subsidiaries, a separate component of equity, in our consolidated balance sheet. When we consolidate securitization VIEs, the third party ownership interests are reflected as VIE liabilities in our consolidated balance sheet because the beneficial interests payable to these third parties are legally issued in the form of debt. Our presentation of net income attributes earnings to controlling and non-controlling interests.

Variable Interest Entities

In addition to the securitization VIEs, we have financed pools of our loans through collateralized loan obligations (“CLOs”) and a single asset securitization ("SASB"), which are considered VIEs. We also hold interests in certain other entities which are considered VIEs as the limited partners of those entities with equity at risk do not collectively possess (i) the right to remove the general partner or dissolve the partnership without cause or (ii) the right to participate in significant decisions made by the partnership.

We evaluate all of our interests in VIEs for consolidation. When our interests are determined to be variable interests, we assess whether we are deemed to be the primary beneficiary of the VIE. The primary beneficiary of a VIE is required to consolidate the VIE. Accounting Standards Codification (“ASC”) 810, Consolidation, defines the primary beneficiary as the party that has both (i) the power to direct the activities of the VIE that most significantly impact its economic performance, and (ii) the obligation to absorb losses and the right to receive benefits from the VIE which could be potentially significant. We consider our variable interests as well as any variable interests of our related parties in making this determination. Where both of these factors are present, we are deemed to be the primary beneficiary and we consolidate the VIE. Where either one of these factors is not present, we are not the primary beneficiary and do not consolidate the VIE.

To assess whether we have the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, we consider all facts and circumstances, including our role in establishing the VIE and our ongoing rights and responsibilities. This assessment includes: (i) identifying the activities that most significantly impact the VIE’s economic performance; and (ii) identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE or have the right to unilaterally remove those decision makers are deemed to have the power to direct the activities of a VIE. The right to remove the decision maker in a VIE must be exercisable without cause for the decision maker to not be deemed the party that has the power to direct the activities of a VIE.

To assess whether we have the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, we consider all of our economic interests, including debt and equity investments, servicing fees and other arrangements deemed to be variable interests in the VIE. This assessment requires that we apply judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Factors considered in assessing significance include: the design of the VIE, including its capitalization structure; subordination of interests; payment priority; relative share of interests held across various classes within the VIE’s capital structure; and the reasons why the interests are held by us.

Our purchased investment securities include unrated and non-investment grade rated securities issued by securitization trusts. In certain cases, we may contract to provide special servicing activities for these trusts, or, as holder of the controlling class, we may have the right to name and remove the special servicer for these trusts. In our role as special servicer, we provide services on defaulted loans within the trusts, such as foreclosure or work-out procedures, as permitted by the underlying contractual agreements. In exchange for these services, we receive a fee. These rights give us the ability to direct activities that could significantly impact the trust’s economic performance. However, in those instances where an unrelated third party has the right to unilaterally remove us as special servicer without cause, we do not have the power to direct activities that most significantly impact the trust’s economic performance. We evaluated all of our positions in such investments for consolidation.

For securitization VIEs in which we are determined to be the primary beneficiary, all of the underlying assets, liabilities and equity of the structures are recorded on our books, and the initial investment, along with any associated unrealized holding gains and losses, are eliminated in consolidation. Similarly, the interest income earned from these structures, as well as the fees paid by these trusts to us in our capacity as special servicer, are eliminated in consolidation. Further, a portion of the identified servicing intangible asset associated with the servicing fee streams, and the corresponding amortization or change in fair value of the servicing intangible asset, are also eliminated in consolidation.

We perform ongoing reassessments of: (i) whether any entities previously evaluated under the majority voting interest framework have become VIEs, based on certain events, and therefore subject to the VIE consolidation framework, and (ii) whether changes in the facts and circumstances regarding our involvement with a VIE causes our consolidation conclusion regarding the VIE to change.

We elect the fair value option for initial and subsequent recognition of the assets and liabilities of our consolidated securitization VIEs. Interest income and interest expense associated with these VIEs are no longer relevant on a standalone basis because these amounts are already reflected in the fair value changes. We have elected to present these items in a single line on our consolidated statements of operations. The residual difference shown on our consolidated statements of operations in the line item “Change in net assets related to consolidated VIEs” represents our beneficial interest in the VIEs.

We separately present the assets and liabilities of our consolidated securitization VIEs as individual line items on our consolidated balance sheets. The liabilities of our consolidated securitization VIEs consist solely of obligations to the bondholders of the related trusts, and are thus presented as a single line item entitled “VIE liabilities.” The assets of our consolidated securitization VIEs consist principally of loans, but at times, also include foreclosed loans which have been temporarily converted into real estate owned (“REO”). These assets in the aggregate are likewise presented as a single line item entitled “VIE assets.”

Loans comprise the vast majority of our securitization VIE assets and are carried at fair value due to the election of the fair value option. When an asset becomes REO, it is due to non-performance of the loan. Because the loan is already at fair value, the carrying value of an REO asset is also initially at fair value. Furthermore, when we consolidate a trust, any existing REO would be consolidated at fair value. Once an asset becomes REO, its disposition time is relatively short. As a result, the carrying value of an REO generally approximates fair value under GAAP.

In addition to sharing a similar measurement method as the loans in a trust, the securitization VIE assets as a whole can only be used to settle the obligations of the consolidated VIE. The assets of our securitization VIEs are not individually accessible by the bondholders, which creates inherent limitations from a valuation perspective. Also creating limitations from a valuation perspective is our role as special servicer, which provides us very limited visibility, if any, into the performing loans of a trust.

REO assets generally represent a very small percentage of the overall asset pool of a trust. In new issue trusts there are no REO assets. We estimate that REO assets constitute approximately 1% of our consolidated securitization VIE assets, with the remaining 99% representing loans. However, it is important to note that the fair value of our securitization VIE assets is determined by reference to our securitization VIE liabilities as permitted under Accounting Standard Update ("ASU") 2014-13, Consolidation (Topic 810): Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized Financing Entity. In other words, our VIE liabilities are more reliably measurable than the VIE assets, resulting in our current measurement methodology which utilizes this value to determine the fair value of our securitization VIE assets as a whole. As a result, these percentages are not necessarily indicative of the relative fair values of each of these asset categories if the assets were to be valued individually.

Due to our accounting policy election under ASU 2014-13, separately presenting two different asset categories would result in an arbitrary assignment of value to each, with one asset category representing a residual amount, as opposed to its fair value. However, as a pool, the fair value of the assets in total is equal to the fair value of the liabilities.

For these reasons, the assets of our securitization VIEs are presented in the aggregate.

Fair Value Option

The guidance in ASC 825, Financial Instruments, provides a fair value option election that allows entities to make an irrevocable election of fair value as the initial and subsequent measurement attribute for certain eligible financial assets and liabilities. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings. The decision to elect the fair value option is determined on an instrument by instrument basis and must be applied to an entire instrument and is irrevocable once elected. Assets and liabilities measured at fair value pursuant to this guidance are required to be reported separately in our consolidated balance sheets from those instruments using another accounting method.

We have elected the fair value option for certain eligible financial assets and liabilities of our consolidated securitization VIEs, residential loans held-for-investment, loans held-for-sale originated or acquired for future securitization and purchased CMBS issued by VIEs we could consolidate in the future. The fair value elections for VIE and securitization related items were made in order to mitigate accounting mismatches between the carrying value of the instruments and the related assets and liabilities that we consolidate at fair value. The fair value elections for residential loans held-for-investment were made in order to maintain consistency across all our residential loans. The fair value elections for mortgage loans held-for-sale were made due to the expected short-term holding period of these instruments.

Fair Value Measurements

We measure our mortgage-backed securities, investments of consolidated affordable housing fund, derivative assets and liabilities, domestic servicing rights intangible asset and any assets or liabilities where we have elected the fair value option at fair value. When actively quoted observable prices are not available, we either use implied pricing from similar assets and liabilities or valuation models based on net present values of estimated future cash flows, adjusted as appropriate for liquidity, credit, market and/or other risk factors.

As discussed above, we measure the assets and liabilities of consolidated securitization VIEs at fair value pursuant to our election of the fair value option. The securitization VIEs in which we invest are “static”; that is, no reinvestment is permitted, and there is no active management of the underlying assets. In determining the fair value of the assets and liabilities of the securitization VIEs, we maximize the use of observable inputs over unobservable inputs. Refer to Note 21 for further discussion regarding our fair value measurements.

Valuation Process

We have valuation control processes in place to validate the fair value of the Company’s financial assets and liabilities measured at fair value including those derived from pricing models. These control processes are designed to assure that the values used for financial reporting are based on observable inputs wherever possible. In the event that observable inputs are not available, the control processes are designed to assure that the valuation approach utilized is appropriate and consistently applied and the assumptions are reasonable.

Pricing Verification—We use recently executed transactions, other observable market data such as exchange data, broker/dealer quotes, third party pricing vendors and aggregation services for validating the fair values generated using valuation models. Pricing data provided by approved external sources is evaluated using a number of approaches; for example, by corroborating the external sources’ prices to executed trades, analyzing the methodology and assumptions used by the external source to generate a price and/or by evaluating how active the third party pricing source (or originating sources used by the third party pricing source) is in the market.

Unobservable Inputs—Where inputs are not observable, we review the appropriateness of the proposed valuation methodology to ensure it is consistent with how a market participant would arrive at the unobservable input. The valuation methodologies utilized in the absence of observable inputs may include extrapolation techniques and the use of comparable observable inputs.

Any changes to the valuation methodology will be reviewed by our management to ensure the changes are appropriate. The methods used may produce a fair value calculation that is not indicative of net realizable value or reflective of future fair values. Furthermore, while we anticipate that our valuation methods are appropriate and consistent with other market participants, the use of different methodologies, or assumptions, to determine the fair value could result in a different estimate of fair value at the reporting date.

Fair Value on a Recurring Basis

We determine the fair value of our financial assets and liabilities measured at fair value on a recurring basis as follows:

Loans held-for-sale, commercial

We measure the fair value of our commercial mortgage loans held-for-sale using a discounted cash flow analysis unless observable market data (i.e., securitized pricing) is available. A discounted cash flow analysis requires management to make estimates regarding future interest rates and credit spreads. The most significant of these inputs relates to credit spreads and is unobservable. Thus, we have determined that the fair values of mortgage loans valued using a discounted cash flow analysis should be classified in Level III of the fair value hierarchy, while mortgage loans valued using securitized pricing should be classified in Level II of the fair value hierarchy. Mortgage loans classified in Level III are transferred to Level II if securitized pricing becomes available.

Loans held-for-sale and loans held-for-investment, residential

We measure the fair value of our residential loans held-for-sale and held-for-investment based on the net present value of expected future cash flows using a combination of observable and unobservable inputs. Observable market participant assumptions include pricing related to trades of residential loans with similar characteristics. Unobservable inputs include the expectation of future cash flows, which involves judgments about the underlying collateral, the creditworthiness of the borrower, estimated prepayment speeds, estimated future credit losses, forward interest rates, investor yield requirements and certain other factors. At each measurement date, we consider both the observable and unobservable valuation inputs in the determination of fair value. However, given the significance of the unobservable inputs, these loans have been classified within Level III.

RMBS

RMBS are valued utilizing observable and unobservable market inputs. The observable market inputs include recent transactions, broker quotes and vendor prices (“market data”). However, given the implied price dispersion amongst the market data, the fair value determination for RMBS has also utilized significant unobservable inputs in discounted cash flow models including prepayments, default and severity estimates based on the recent performance of the collateral, the underlying collateral characteristics, industry trends, as well as expectations of macroeconomic events (e.g., housing price curves, interest rate curves, etc.). At each measurement date, we consider both the observable and unobservable valuation inputs in the determination of fair value. However, given the significance of the unobservable inputs these securities have been classified within Level III.

CMBS

CMBS are valued utilizing both observable and unobservable market inputs. These factors include projected future cash flows, ratings, subordination levels, vintage, remaining lives, credit issues, recent trades of similar securities and the spreads used in the prior valuation. We obtain current market spread information where available and use this information in evaluating and validating the market price of all CMBS. Depending upon the significance of the fair value inputs used in determining these fair values, these securities are classified in either Level II or Level III of the fair value hierarchy. CMBS may shift between Level II and Level III of the fair value hierarchy if the significant fair value inputs used to price the CMBS become or cease to be observable.

Equity security

The equity security is publicly registered and traded in the U.S. and its market price is listed on the London Stock Exchange. The security has been classified within Level I.

Woodstar Fund Investments

The fair value of investments held by the Woodstar Fund is determined based on observable and unobservable market inputs. The initial fair value of the Woodstar Fund's investments at its November 5, 2021 establishment date was determined by reference to the purchase price paid by third party investors, which was consistent with both a recent external appraisal as well as our extensive marketing efforts to sell interests in the Woodstar Fund, plus working capital.

For the properties, the third party appraisal applied the income capitalization approach with corroborative support from the sales comparison approach. The cost approach is not employed, as it is typically not emphasized by potential investors in the multifamily affordable housing sector. The income capitalization approach estimates an income stream for a property over a 10-year period and discounts this income plus a reversion (presumed sale) into a present value at a risk adjusted discount rate. Terminal capitalization rates and discount rates utilized in this approach are derived from market transactions as well as other financial and industry data.

For secured financing, the third party appraisal discounted the contractual cash flows at the interest rate at which such arrangements would bear if executed in the current market. The fair value of investment level working capital is assumed to approximate carrying value due to its primarily short-term monetary nature. The fair value of interest rate derivatives is determined using the methodology described in the Derivatives discussion below.

Given the significance of the unobservable inputs used in the respective valuations, the Woodstar Fund’s investments have been classified within Level III of the fair value hierarchy.

Domestic servicing rights

The fair value of this intangible is determined using discounted cash flow modeling techniques which require management to make estimates regarding future net servicing cash flows, including forecasted loan defeasance, control migration, delinquency and anticipated maturity defaults which are calculated assuming a debt yield at which default occurs. Since the most significant of these inputs are unobservable, we have determined that the fair values of this intangible in its entirety should be classified in Level III of the fair value hierarchy.

Derivatives

The valuation of derivative contracts are determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market based inputs, including interest rate curves, spot and market forward points and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves.

We incorporate credit valuation adjustments to appropriately reflect both our own non-performance risk and the respective counterparty’s non-performance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of non-performance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

The valuation of over the counter derivatives are determined using discounted cash flows based on Overnight Index Swap (“OIS”) rates. Fully collateralized trades are discounted using OIS with no additional economic adjustments to arrive at fair value. Uncollateralized or partially collateralized trades are also discounted at OIS, but include appropriate economic adjustments for funding costs (i.e., a LIBOR OIS basis adjustment to approximate uncollateralized cost of funds) and credit risk. For credit index instruments, fair value is determined based on changes in the relevant indices from the date of initiation of the instrument to the reporting date, as these changes determine the amount of any future cash settlement between us and the counterparty. These indices are considered Level II inputs as they are directly observable.

Although we have determined that the majority of the inputs used to value our derivatives fall within Level II of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level III inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. However, as of December 31, 2021 and 2020, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined that our derivative valuations in their entirety are classified in Level II of the fair value hierarchy.

Liabilities of consolidated VIEs

Our consolidated VIE liabilities generally represent bonds that are not owned by us. The majority of these are either traded in the marketplace or can be analogized to similar securities that are traded in the marketplace. For these liabilities, pricing is considered to be Level II, where the valuation is based upon quoted prices for similar instruments traded in active markets. We generally utilize third party pricing service providers for valuing these liabilities. In order to determine whether to utilize the valuations provided by third parties, we conduct an ongoing evaluation of their valuation methodologies and processes, as well as a review of the individual valuations themselves. In evaluating third party pricing for reasonableness, we consider a variety of factors, including market transaction information for the particular bond, market transaction information for bonds within the same trust, market transaction information for similar bonds, the bond’s ratings and the bond’s subordination levels.

For the minority portion of our consolidated VIE liabilities which consist of unrated or non-investment grade bonds that are not owned by us, pricing may be either Level II or Level III. If independent third party pricing similar to that noted above is available, we consider the valuation to be Level II. If such third party pricing is not available, the valuation is generated from model-based techniques that use significant unobservable assumptions, and we consider the valuation to be Level III. For VIE liabilities classified as Level III, valuation is determined based on discounted expected future cash flows which take into consideration expected duration and yields based on market transaction information, ratings, subordination levels, vintage and current market spread. VIE liabilities may shift between Level II and Level III of the fair value hierarchy if the significant fair value inputs used to price the VIE liabilities become or cease to be observable.

Assets of consolidated VIEs

The securitization VIEs in which we invest are “static”; that is, no reinvestment is permitted, and there is no active management of the underlying assets. In determining the fair value of the assets of the VIE, we maximize the use of observable inputs over unobservable inputs. The individual assets of a VIE are inherently incapable of precise measurement given their illiquid nature and the limitations on available information related to these assets. Because our methodology for valuing these assets does not value the individual assets of a VIE, but rather uses the value of the VIE liabilities as an indicator of the fair value of VIE assets as a whole, we have determined that our valuations of VIE assets in their entirety should be classified in Level III of the fair value hierarchy.

Fair Value Only Disclosed

We determine the fair value of our financial instruments and assets where fair value is disclosed as follows:

Loans held-for-investment and loans held-for-sale

We estimate the fair values of our loans not carried at fair value on a recurring basis by discounting their expected cash flows at a rate we estimate would be demanded by the market participants that are most likely to buy our loans. The expected cash flows used are generally the same as those used to calculate our level yield income in the financial statements. Since these inputs are unobservable, we have determined that the fair value of these loans in their entirety would be classified in Level III of the fair value hierarchy.

HTM debt securities

We estimate the fair value of our mandatorily redeemable preferred equity interests in commercial real estate companies and infrastructure bonds using the same methodology described for our loans held-for-investment. We estimate the fair value of our HTM CMBS using the same methodology described for our CMBS carried at fair value on a recurring basis.

Secured financing agreements, CLOs and SASB

The fair value of the secured financing agreements, CLOs and SASB are determined by discounting the contractual cash flows at the interest rate we estimate such arrangements would bear if executed in the current market. We have determined that our valuation of these instruments should be classified in Level III of the fair value hierarchy.

Unsecured senior notes

The fair value of our unsecured senior notes is determined based on the last available bid price for the respective notes in the current market. As these prices represent observable market data, we have determined that the fair value of these instruments would be classified in Level II of the fair value hierarchy.

Business Combinations

Under ASC 805, Business Combinations, the acquirer in a business combination must recognize, with certain exceptions, the fair values of assets acquired, liabilities assumed, and non-controlling interests when the acquisition constitutes a change in control of the acquired entity. As goodwill is calculated as a residual, all goodwill of the acquired business, not just the acquirer’s share, is recognized under this “full goodwill” approach. During the measurement period, a period which shall not exceed one year, we prospectively adjust the provisional amounts recognized to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized.

We apply the asset acquisition provisions of ASC 805 in accounting for acquisitions of real estate with in-place leases where substantially all of the fair value of the assets acquired is concentrated in either a single identifiable asset or group of similar identifiable assets. This results in the acquired properties being recognized initially at their purchase price inclusive of acquisition costs, which are capitalized. All other acquisitions of real estate with in-place leases are accounted for in accordance with the business combination provisions of ASC 805. We also apply the asset acquisition provisions of ASC 805 for acquired real estate assets where a lease is entered into concurrently with the acquisition of the asset, such as in sale leaseback transactions.

Cash and Cash Equivalents

Cash and cash equivalents include cash in banks and short‑term investments. Short‑term investments are comprised of highly liquid instruments with original maturities of three months or less. The Company maintains its cash and cash equivalents in multiple financial institutions and at times these balances exceed federally insurable limits.

Restricted Cash

Restricted CashRestricted cash includes cash and cash equivalents that are legally or contractually restricted as to withdrawal or usage and primarily includes (i) cash collateral associated with derivative financial instruments, (ii) loan payments received by our Infrastructure Lending Segment which are restricted by our lender and periodically applied, in part, to the outstanding balance of the Infrastructure Lending debt facility and (iii) funds held on behalf of borrowers and tenants.

Loans Held-for-Investment

Loans that are held for investment (“HFI”) are carried at cost, net of unamortized acquisition premiums or discounts, loan fees and origination costs, as applicable, and net of credit loss allowances as discussed below, unless we have elected to apply the fair value option at purchase.

Loans Held-For-Sale

Our loans that we intend to sell or liquidate in the short-term are classified as held-for-sale and are carried at the lower of amortized cost or fair value, unless we have elected to apply the fair value option at origination or purchase. We periodically enter into derivative financial instruments to hedge unpredictable changes in fair value of loans held-for-sale, including changes resulting from both interest rates and credit quality. Because these derivatives are not designated, changes in their fair value are recorded in earnings. In order to best reflect the results of the hedged loan portfolio in earnings, we have elected the fair value option for these loans. As a result, changes in the fair value of the loans are also recorded in earnings.

Investment Securities

We designate our debt investment securities as held-to-maturity (“HTM”), available-for-sale (“AFS”), or trading depending on our investment strategy and ability to hold such securities to maturity. HTM debt securities where we have not elected to apply the fair value option are stated at cost plus any premiums or discounts, which are amortized or accreted through the consolidated statements of operations using the effective interest method. Debt securities we (i) do not hold for the purpose of selling in the near-term, or (ii) may dispose of prior to maturity, are classified as AFS and are carried at fair value in the

accompanying financial statements. Unrealized gains or losses on AFS debt securities where we have not elected the fair value option are reported as a component of accumulated other comprehensive income (“AOCI”) in stockholders’ equity. Our HTM and AFS debt securities are also subject to credit loss allowances as discussed below.

Our only equity investment security is carried at fair value, with unrealized holding gains and losses recorded in earnings.

Credit Losses

Loans and Debt Securities Measured at Amortized Cost

ASC 326, Financial Instruments – Credit Losses, became effective for the Company on January 1, 2020. ASC 326 mandates the use of a current expected credit loss model (“CECL”) for estimating future credit losses of certain financial instruments measured at amortized cost, instead of the “incurred loss” credit model previously required under GAAP. The CECL model requires the consideration of possible credit losses over the life of an instrument as opposed to only estimating credit losses upon the occurrence of a discrete loss event under the previous “incurred loss” methodology. The CECL model applies to our HFI loans and our HTM debt securities which are carried at amortized cost, including future funding commitments and accrued interest receivable related to those loans and securities. However, as permitted by ASC 326, we have elected not to measure an allowance for credit losses on accrued interest receivable (which is classified separately on our consolidated balance sheet), but rather write off in a timely manner by reversing interest income and/or cease accruing interest that would likely be uncollectible. Our adoption of the CECL model resulted in a $32.3 million increase to our total allowance for credit losses, which was recognized as a cumulative-effect adjustment to accumulated deficit as of January 1, 2020.

As we do not have a history of realized credit losses on our HFI loans and HTM securities, we have subscribed to third party database services to provide us with historical industry losses for both commercial real estate and infrastructure loans. Using these losses as a benchmark, we determine expected credit losses for our loans and securities on a collective basis within our commercial real estate and infrastructure portfolios. See Note 5 for further discussion of our methodologies.

We also evaluate each loan and security measured at amortized cost for credit deterioration at least quarterly. Credit deterioration occurs when it is deemed probable that we will not be able to collect all amounts due according to the contractual terms of the loan or security. If a loan or security is considered to be credit deteriorated, we depart from the industry loss rate approach described above and determine the credit loss allowance as any excess of the amortized cost basis of the loan or security over (i) the present value of expected future cash flows discounted at the contractual effective interest rate or (ii) the fair value of the collateral, if repayment is expected solely from the collateral.

Available-for-Sale Debt Securities

Separate provisions of ASC 326 apply to our AFS debt securities, which are carried at fair value with unrealized gains and losses reported as a component of AOCI. We are required to establish an initial credit loss allowance for those securities that are purchased with credit deterioration (“PCD”) by grossing up the amortized cost basis of each security and providing an offsetting credit loss allowance for the difference between expected cash flows and contractual cash flows, both on a present value basis. As of the January 1, 2020 effective date, no such credit loss allowance gross-up was required on our AFS debt securities with PCD due to their individual unrealized gain positions as of that date.

Subsequently, cumulative adverse changes in expected cash flows on our AFS debt securities are recognized currently as an increase to the allowance for credit losses. However, the allowance is limited to the amount by which the AFS debt security’s amortized cost exceeds its fair value. Favorable changes in expected cash flows are first recognized as a decrease to the allowance for credit losses (recognized currently in earnings). Such changes would be recognized as a prospective yield adjustment only when the allowance for credit losses is reduced to zero. A change in expected cash flows that is attributable solely to a change in a variable interest reference rate does not result in a credit loss and is accounted for as a prospective yield adjustment.

Properties Held-For-Investment

Properties, net, as reported on our consolidated balance sheets, consist of commercial real estate properties held-for-investment and are recorded at cost, less accumulated depreciation and impairments, if any. Properties consist primarily of land, buildings and improvements. Land is not depreciated, and buildings and improvements are depreciated on a straight-line basis over their estimated useful lives. Ordinary repairs and maintenance are expensed as incurred; major replacements and

betterments are capitalized and depreciated on a straight-line basis over their estimated useful lives. We review properties for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. Recoverability is determined by comparing the carrying amount of the property to the undiscounted future net cash flows it is expected to generate. If such carrying amount exceeds the expected undiscounted future net cash flows, we adjust the carrying amount of the property to its estimated fair value.

Properties Held-For-Sale

Properties Held-For-SaleProperties and any associated intangible assets are presented within properties held-for-sale on our consolidated balance sheet when the sale of the property is considered probable, at which time we cease depreciation and amortization of the property and the associated intangibles. Held-for-sale properties are reported at the lower of their carrying value or fair value less costs to sell.

Investments in Unconsolidated Entities

We own non‑controlling equity interests in various privately‑held partnerships and limited liability companies. Unless we elect the fair value option under ASC 825, we use the fair value practicability election described below to account for investments in which our interest is so minor that we have virtually no influence over the underlying investees. We use the equity method to account for all other non‑controlling interests in partnerships and limited liability companies. Equity method investments are initially recorded at cost and subsequently adjusted for our share of income or loss, as well as contributions made or distributions received.

Our other equity investments set forth in Note 9 do not have readily determinable fair values. Therefore, we have elected the fair value practicability exception under ASC 321, Equity Securities, whereby we measure those investments within its scope at cost, less any impairment, plus or minus observable price changes from orderly transactions of identical or similar investments of the same issuer. Our former investment in Federal Home Loan Bank (“FHLB”) stock, which is not within the scope of ASC 321, was carried at cost less any impairment.

We review our equity method and other investments not subject to the fair value practicability election for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. For our investments under the fair value practicability election, we perform a qualitative assessment to identify impairment at the end of each reporting period. An impairment loss is measured based on the excess of the carrying amount of an investment over its estimated fair value. Impairment analyses are based on current plans, intended holding periods, estimated fair values of underlying assets and available information at the time the analyses are prepared.

Goodwill

Goodwill is not amortized, but rather tested for impairment annually or more frequently if events or changes in circumstances indicate potential impairment. Goodwill at December 31, 2021 represents the excess of the consideration paid over the fair value of net assets acquired in connection with the acquisitions of LNR Property LLC (“LNR”) in April 2013 and the Infrastructure Lending Segment in September 2018 and October 2018.

In testing goodwill for impairment, we follow ASC 350, Intangibles—Goodwill and Other, which permits a qualitative assessment of whether it is more likely than not that the fair value of a reporting unit is less than its carrying value including goodwill. If the qualitative assessment determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying value including goodwill, then no impairment is determined to exist for the reporting unit. However, if the qualitative assessment determines that it is more likely than not that the fair value of the reporting unit is less than its carrying value including goodwill, or we choose not to perform the qualitative assessment, then we compare the fair value of that reporting unit with its carrying value, including goodwill. ASU 2017-04, Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment, became effective for the Company on January 1, 2020. This ASU specifies that if the carrying value of a reporting unit exceeds its fair value, goodwill is considered impaired with the impairment loss measured as the excess of the reporting unit’s carrying value (inclusive of goodwill) over its fair value, eliminating the requirement that all assets and liabilities of the reporting unit be remeasured individually in connection with measurement of goodwill impairment.

Servicing Rights Intangibles

Servicing Rights IntangiblesOur identifiable intangible assets include domestic special servicing rights for which we have elected to apply the fair value measurement method, which is necessary to conform to our election of the fair value option for measuring the assets and liabilities of the securitization VIEs consolidated pursuant to ASC 810.

Lease Intangibles

Lease IntangiblesIn connection with our acquisition of properties, we recognize intangible lease assets and liabilities associated with certain noncancelable operating leases of the acquired properties. These intangible lease assets and liabilities include in-place lease intangible assets, favorable lease intangible assets and unfavorable lease liabilities. In-place lease intangible assets reflect the acquired benefit of purchasing properties with in-place leases and are measured based on estimates of direct costs associated with leasing the property and lost rental income during projected lease-up and free rent periods, both of which are avoided due to the presence of in-place leases at the acquisition date. Favorable and unfavorable lease intangible assets and liabilities reflect the terms of in-place tenant leases being either favorable or unfavorable relative to market terms at the acquisition date. The estimated fair values of our favorable and unfavorable lease assets and liabilities at the respective acquisition dates represent the discounted cash flow differential between the contractual cash flows of such leases and the estimated cash flows that comparable leases at market terms would generate. Our intangible lease assets and liabilities are recognized within intangible assets and other liabilities, respectively, in our consolidated balance sheets. Our in-place lease intangible assets are amortized to amortization expense while our favorable and unfavorable lease intangible assets and liabilities where we are the lessor are amortized to rental income. Both our favorable and unfavorable lease intangible assets and liabilities are amortized over the remaining noncancelable term of the respective leases on a straight-line basis.

Leases

On January 1, 2019, ASC 842, Leases, became effective for the Company. ASC 842 establishes a right-of-use model for lessee accounting which results in the recognition of most leased assets and lease liabilities on the balance sheet of the lessee. Lessor accounting was not significantly affected by this ASC. We elected to apply the provisions of ASC 842 as of January 1, 2019 and not to retrospectively adjust prior periods presented. Such application did not result in any cumulative-effect adjustment as of January 1, 2019. We elected the “package of practical expedients” for transition purposes, which permits us not to reassess under the new standard our prior conclusions about lease identification, lease classification and initial direct costs for leases that commenced prior to January 1, 2019. We also elected not to apply the recognition provisions of ASC 842 to short-term leases, which have original lease terms of 12 months or less. As a lessor, we elected not to separate nonlease components, such as reimbursements from tenants for common area maintenance (“CAM”), from lease components for all classes of underlying assets, and continue to recognize such nonlease components ratably in rental income. We also elected to continue to exclude from rental income all sales, use and other similar taxes collected from lessees. As required by ASC 842, we no longer record as revenues and expenses lessor costs (such as property taxes) paid directly by the lessees. The application of ASC 842 has had no material effect on our consolidated financial statements, as all of our leases, as both lessor and lessee, are currently classified as operating leases, which are subject to essentially the same straight-line revenue and expense recognition as in the past.

Derivative Instruments and Hedging Activities

We record all derivatives on our consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on whether we have elected to designate a derivative in a hedging relationship and have satisfied the criteria necessary to apply hedge accounting under GAAP. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. We regularly enter into derivative contracts that are intended to economically hedge certain of our risks, even though the transactions may not qualify for, or we may not elect to pursue, hedge accounting. In such cases, changes in the fair value of the derivatives are recorded in earnings.

Generally, our derivatives are subject to master netting arrangements, though we elect to present all derivative assets and liabilities on a gross basis within our consolidated balance sheets.

Convertible Senior Notes

Effective January 1, 2021, the Company early adopted 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), which removes certain separation models for convertible debt instruments and convertible preferred stock that require the separation into a debt component and an equity or derivative component. Consequently, our convertible senior notes (the “Convertible Notes”), which were previously accounted for as having separate liability and equity components, are now accounted for as a single liability measured at amortized cost. The standard was adopted using the modified retrospective method of transition, which resulted in a cumulative decrease to additional paid-in capital of $3.7 million, partially offset by a cumulative decrease to accumulated deficit of $2.2 million as of January 1, 2021.

Revenue Recognition

Interest Income

Interest income on performing loans and financial instruments is accrued based on the outstanding principal amount and contractual terms of the instrument. For loans where we do not elect the fair value option, origination fees and direct loan origination costs are also recognized in interest income over the loan term as a yield adjustment using the effective interest method. When we elect the fair value option, origination fees and direct loan costs are recorded directly in income and are not deferred. Discounts or premiums associated with the purchase of non-performing loans and investment securities are amortized or accreted into interest income as a yield adjustment on the effective interest method, based on expected cash flows through the expected maturity date of the investment. On at least a quarterly basis, we review and, if appropriate, make adjustments to our cash flow projections.

We cease accruing interest on non-performing loans at the earlier of (i) the loan becoming significantly past due or (ii) management concluding that a full recovery of all interest and principal is doubtful. Interest income on non-accrual loans in which management expects a full recovery of the loan’s outstanding principal balance is only recognized when received in cash. If a full recovery of principal is doubtful, the cost recovery method is applied whereby any cash received is applied to the outstanding principal balance of the loan. A non-accrual loan is returned to accrual status at such time as the loan becomes contractually current and management believes all future principal and interest will be received according to the contractual loan terms.

For loans acquired with deteriorated credit quality, interest income is only recognized to the extent that our estimate of undiscounted expected principal and interest exceeds our investment in the loan. Such excess, if any, is recognized as interest income on a level-yield basis over the life of the loan.

Upon the sale of loans or securities which are not accounted for pursuant to the fair value option, the excess (or deficiency) of net proceeds over the net carrying value of such loans or securities is recognized as a realized gain (loss).

Servicing Fees

We typically seek to be the special servicer on CMBS transactions in which we invest. When we are appointed to serve in this capacity, we earn special servicing fees from the related activities performed, which consist primarily of overseeing the workout of under-performing and non-performing loans underlying the CMBS transactions. These fees are recognized in income in the period in which the services are performed and the revenue recognition criteria have been met.

Rental Income

Rental income is recognized when earned from tenants. For leases that provide rent concessions or fixed escalations over the lease term, rental income is recognized on a straight-line basis over the noncancelable term of the lease. In net lease arrangements, costs reimbursable from tenants are recognized in rental income in the period in which the related expenses are incurred as we are generally the primary obligor with respect to purchasing goods and services for property operations. In instances where the tenant is responsible for property maintenance and repairs and contracts and settles such costs directly with third party service providers, we do not reflect those expenses in our consolidated statement of operations as the tenant is the primary obligor.

Securitizations, Sales and Financing Arrangements

We periodically sell our financial assets, such as commercial mortgage loans, residential loans, CMBS, RMBS and other assets. In connection with these transactions, we may retain or acquire senior or subordinated interests in the related assets. Gains and losses on such transactions are recognized in accordance with ASC 860, Transfers and Servicing, which is based on a financial components approach that focuses on control. Under this approach, after a transfer of financial assets that meets the criteria for treatment as a sale—legal isolation, ability of transferee to pledge or exchange the transferred assets without constraint, and transferred control—an entity recognizes the financial assets it retains and any liabilities it has incurred, derecognizes the financial assets it has sold, and derecognizes liabilities when extinguished. We determine the gain or loss on sale of the assets by allocating the carrying value of the sold asset between the sold asset and the interests retained based on their relative fair values, as applicable. The gain or loss on sale is the difference between the cash proceeds from the sale and the amount allocated to the sold asset. If the sold asset is being accounted for pursuant to the fair value option, there is no gain or loss.

Deferred Financing Costs

Costs incurred in connection with debt issuance are capitalized and amortized to interest expense over the terms of the respective debt agreements. Such costs are presented as a direct deduction from the carrying value of the related debt liability.

Acquisition and Investment Pursuit Costs

Costs incurred in connection with acquisitions of investments, loans and businesses, as well as in pursuing unsuccessful acquisitions and investments, are recorded within acquisition and investment pursuit costs in our consolidated statements of operations when incurred. Costs incurred in connection with acquisitions of real estate not accounted for as business combinations are capitalized within the purchase price. These costs reflect services performed by third parties and principally include due diligence and legal services.

Share-Based Payments

Share‑Based PaymentsThe fair value of the restricted stock (“RSAs”) or restricted stock units (“RSUs”) granted is recorded as expense on a straight‑line basis over the vesting period for the award, with an offsetting increase in stockholders’ equity. The fair value is determined based upon the stock price on the grant date.

Foreign Currency Translation

Our assets and liabilities denominated in foreign currencies are translated into U.S. dollars using foreign currency exchange rates at the end of the reporting period. Income and expenses are translated at the average exchange rates for each reporting period. The effects of translating the assets, liabilities and income of our foreign investments held by entities with a U.S. dollar functional currency are included in foreign currency gain (loss) in the consolidated statements of operations or other comprehensive income (“OCI”) for debt securities available-for-sale for which the fair value option has not been elected. The effects of translating the assets, liabilities and income of our foreign investments held by entities with functional currencies other than the U.S. dollar are included in OCI. Realized foreign currency gains and losses and changes in the value of foreign

currency denominated monetary assets and liabilities are included in the determination of net income and are reported as foreign currency gain (loss) in our consolidated statements of operations.

Income Taxes

The Company has elected to be taxed as a REIT under the Code. The Company is subject to federal income taxation at corporate rates on its REIT taxable income, however, the Company is allowed a deduction for the amount of dividends paid to its stockholders in arriving at its REIT taxable income. As a result, distributed net income of the Company is subjected to taxation at the stockholder level only. The Company intends to continue operating in a manner that will permit it to maintain its qualification as a REIT for tax purposes.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company evaluates the realizability of its deferred tax assets and recognizes a valuation allowance if, based on the available evidence, both positive and negative, it is more likely than not that some portion or all of its deferred tax assets will not be realized. When evaluating the realizability of its deferred tax assets, the Company considers, among other matters, estimates of expected future taxable income, nature of current and cumulative losses, existing and projected book/tax differences, tax planning strategies available, and the general and industry specific economic outlook. This realizability analysis is inherently subjective, as it requires the Company to forecast its business and general economic environment in future periods.

We recognize tax positions in the financial statements only when it is more likely than not that, based on the technical merits of the tax position, the position will be sustained upon examination by the relevant taxing authority. A tax position is measured at the largest amount of benefit that will more likely than not be realized upon settlement. If, as a result of new events or information, a recognized tax position no longer is considered more likely than not to be sustained upon examination, a liability is established for the unrecognized benefit with a corresponding charge to income tax expense in our consolidated statement of operations. We report interest and penalties, if any, related to income tax matters as a component of income tax expense.

Earnings Per Share

We present both basic and diluted earnings per share (“EPS”) amounts in our financial statements. Basic EPS excludes dilution and is computed by dividing income available to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Diluted EPS reflects the maximum potential dilution that could occur from (i) our share-based compensation, consisting of unvested RSAs and RSUs, (ii) shares contingently issuable to our Manager, (iii) the conversion options associated with our Convertible Notes (see Notes 12 and 19) and (iv) non-controlling interests that are redeemable with our common stock (see Note 18). Potential dilutive shares are excluded from the calculation if they have an anti-dilutive effect in the period.

Nearly all of the Company’s unvested RSUs and RSAs contain rights to receive non-forfeitable dividends and thus are participating securities. In addition, the non-controlling interests that are redeemable with our common stock are considered participating securities because they earn a preferred return indexed to the dividend rate on our common stock (see Note 18). Due to the existence of these participating securities, the two-class method of computing EPS is required, unless another method is determined to be more dilutive. Under the two-class method, undistributed earnings are reallocated between shares of common stock and participating securities. For the years ended December 31, 2021, 2020 and 2019, the two-class method resulted in the most dilutive EPS calculation.

Concentration of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash investments, CMBS, RMBS, loan investments and interest receivable. We may place cash investments in excess of insured amounts with high quality financial institutions. We perform an ongoing analysis of credit risk concentrations in our investment portfolio by evaluating exposure to various counterparties, markets, underlying property types, contract terms, tenant mix and other credit metrics.

Use of Estimates

The preparation of 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 at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting periods. The most significant and

subjective estimate that we make is the projection of cash flows we expect to receive on our investments, which has a significant impact on the amount of income that we record and/or disclose. In addition, the fair value of assets and liabilities that are estimated using a discounted cash flows method is significantly impacted by the rates at which we estimate market participants would discount the expected cash flows.

We believe the estimates and assumptions underlying our consolidated financial statements are reasonable and supportable based on the information available as of December 31, 2021. However, uncertainty over the ultimate impact the COVID-19 pandemic, including variants and resurgences, will have on the global economy generally, and our business in particular, makes any estimates and assumptions as of December 31, 2021 inherently less certain than they would be absent the current and potential impacts of COVID-19. Actual results may ultimately differ from those estimates.

Recent Accounting Developments

On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) – Facilitation of the Effects of Reference Rate Reform on Financial Reporting, and on January 11, 2021, issued ASU 2021-01, Reference Rate Reform (Topic 848) – Scope, both of which provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or other reference rates expected to be discontinued because of reference rate reform. These ASUs are effective through December 31, 2022. The Company has not adopted any of the optional expedients or exceptions through December 31, 2021, but will continue to evaluate the possible adoption of any such expedients or exceptions during the effective period as circumstances evolve.
