Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies 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, an allocable portion of the identified servicing intangible associated with the eliminated fee streams is eliminated in consolidation. Refer to the segment data in Note 22 for a presentation of our business segments without consolidation of these VIEs. Basis of Accounting and Principles of Consolidation The accompanying condensed consolidated financial statements include our accounts and those of our consolidated subsidiaries and VIEs. Intercompany amounts have been eliminated in consolidation. In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows have been included. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (our “Form 10-K”), as filed with the Securities and Exchange Commission (“SEC”). The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the operating results for the full year. Refer to our Form 10-K for a description of our recurring accounting policies. We have included disclosure in this Note 2 regarding principles of consolidation and other accounting policies that (i) are required to be disclosed quarterly, (ii) we view as critical, (iii) became significant since December 31, 2018 due to a corporate action or increase in the significance of the underlying business activity or (iv) changed upon adoption of an Accounting Standards Update (“ASU”) issued by the Financial Accounting Standards Board (“FASB”). Variable Interest Entities In addition to the securitization VIEs, certain other entities in which we hold interests are considered VIEs as the limited partners of these 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, an allocable portion of the identified servicing intangible asset associated with the servicing fee streams, and the corresponding allocable 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 condensed consolidated statements of operations. The residual difference shown on our condensed 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 condensed 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 nonperformance 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 2% of our consolidated securitization VIE assets, with the remaining 98% 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 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 eligible financial assets and liabilities of our consolidated securitization VIEs, 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 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, 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 19 for further discussion regarding our fair value measurements. Loans Held-for-Investment Loans that are held for investment are carried at cost, net of unamortized acquisition premiums or discounts, loan fees, and origination costs as applicable, unless the loans are deemed impaired. Loan Impairment We evaluate each loan classified as held-for-investment for impairment at least quarterly. Impairment 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. If a loan is considered to be impaired, we record an allowance through the provision for loan losses to reduce the carrying value of the loan to the present value of expected future cash flows discounted at the loan’s contractual effective rate or the fair value of the collateral, if repayment is expected solely from the collateral. There may be circumstances where we modify a loan by granting the borrower a concession that we might not otherwise consider when a borrower is experiencing financial difficulty or is expected to experience financial difficulty in the foreseeable future. Such concessionary modifications are classified as troubled debt restructurings (“TDRs”) unless the modification solely results in a delay in payment that is insignificant. Loans classified as TDRs are considered impaired loans for reporting and measurement purposes. 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. 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. As a lessee, our only significant long-term lease as of January 1, 2019 resulted in the recognition of a $12.0 million lease liability and corresponding right-of-use asset, which are classified within “Accounts payable, accrued expenses and other liabilities” and “Other assets”, respectively, in our condensed consolidated balance sheet as of June 30, 2019. 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 restricted stock (“RSAs”) and restricted stock units (“RSUs”), (ii) shares contingently issuable to our Manager, (iii) the conversion options associated with our outstanding convertible senior notes (the “Convertible Notes”) (see Notes 10 and 17), and (iv) non-controlling interests that are redeemable with our common stock (see Note 16). 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 16). 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 three and six months ended June 30, 2019 and 2018, the two-class method resulted in the most dilutive EPS calculation. 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. Actual results could differ from those estimates. The most significant and subjective estimate that we make is the projection of cash flows we expect to receive on our loans, investment securities and intangible assets, which has a significant impact on the amounts of interest income, credit losses (if any) and fair values that we record and/or disclose. In addition, the fair value of financial 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. Recent Accounting Developments On June 16, 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments, which mandates use of an “expected loss” credit model for estimating future credit losses of certain financial instruments instead of the “incurred loss” credit model that current GAAP requires. The “expected loss” 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 in accordance with the current “incurred loss” methodology. This ASU is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2019. Though we have not completed our assessment of this ASU, we expect this ASU to result in our recognition of higher levels of allowances for loan losses. Our assessment of the estimated amount of such increases remains in process. On January 26, 2017, the FASB issued ASU 2017-04, Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment, which simplifies the method applied for measuring impairment in cases where goodwill is impaired. This ASU specifies that goodwill impairment will be 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. This ASU is effective for annual periods, and interim periods therein, beginning after December 15, 2019 and is applied prospectively. Early application is permitted. We do not expect the application of this ASU to materially impact the Company. On August 28, 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) – Disclosure Framework, which adds new disclosure requirements and modifies or eliminates existing disclosure requirements of ASC 820. This ASU is effective for annual periods, and interim periods therein, beginning after December 15, 2019. Early application is permitted. We do not expect the application of this ASU to materially impact the Company, as it only affects fair value disclosures. On October 31, 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810) – Targeted Improvements to Related Party Guidance for Variable Interest Entities, which requires reporting entities to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety for determining whether a decision-making fee is a variable interest. This ASU is effective for annual periods, and interim periods therein, beginning after December 15, 2019. Early application is permitted. We are in the process of assessing the impact this ASU will have on the Company, but do not expect it to be material.

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, an allocable portion of the identified servicing intangible associated with the eliminated fee streams is eliminated in consolidation.

Refer to the segment data in Note 22 for a presentation of our business segments without consolidation of these VIEs.

Basis of Accounting and Principles of Consolidation

The accompanying condensed consolidated financial statements include our accounts and those of our consolidated subsidiaries and VIEs. Intercompany amounts have been eliminated in consolidation. In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations, and cash flows have been included.

These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 (our “Form 10-K”), as filed with the Securities and Exchange Commission (“SEC”). The results of operations for the three and six months ended June 30, 2019 are not necessarily indicative of the operating results for the full year.

Refer to our Form 10-K for a description of our recurring accounting policies. We have included disclosure in this Note 2 regarding principles of consolidation and other accounting policies that (i) are required to be disclosed quarterly, (ii) we view as critical, (iii) became significant since December 31, 2018 due to a corporate action or increase in the significance of the underlying business activity or (iv) changed upon adoption of an Accounting Standards Update (“ASU”) issued by the Financial Accounting Standards Board (“FASB”).

Variable Interest Entities

In addition to the securitization VIEs, certain other entities in which we hold interests are considered VIEs as the limited partners of these 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, an allocable portion of the identified servicing intangible asset associated with the servicing fee streams, and the corresponding allocable 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 condensed consolidated statements of operations. The residual difference shown on our condensed 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 condensed 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 nonperformance 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 2% of our consolidated securitization VIE assets, with the remaining 98% 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 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 eligible financial assets and liabilities of our consolidated securitization VIEs, 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 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, 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 19 for further discussion regarding our fair value measurements.

Loans Held-for-Investment

Loans that are held for investment are carried at cost, net of unamortized acquisition premiums or discounts, loan fees, and origination costs as applicable, unless the loans are deemed impaired.

Loan Impairment

We evaluate each loan classified as held-for-investment for impairment at least quarterly. Impairment 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. If a loan is considered to be impaired, we record an allowance through the provision for loan losses to reduce the carrying value of the loan to the present value of expected future cash flows discounted at the loan’s contractual effective rate or the fair value of the collateral, if repayment is expected solely from the collateral.

There may be circumstances where we modify a loan by granting the borrower a concession that we might not otherwise consider when a borrower is experiencing financial difficulty or is expected to experience financial difficulty in the foreseeable future. Such concessionary modifications are classified as troubled debt restructurings (“TDRs”) unless the modification solely results in a delay in payment that is insignificant. Loans classified as TDRs are considered impaired loans for reporting and measurement purposes.

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.

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. As a lessee, our only significant long-term lease as of January 1, 2019 resulted in the recognition of a $12.0 million lease liability and corresponding right-of-use asset, which are classified within “Accounts payable, accrued expenses and other liabilities” and “Other assets”, respectively, in our condensed consolidated balance sheet as of June 30, 2019.

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 restricted stock (“RSAs”) and restricted stock units (“RSUs”), (ii) shares contingently issuable to our Manager, (iii) the conversion options associated with our outstanding convertible senior notes (the “Convertible Notes”) (see Notes 10 and 17), and (iv) non-controlling interests that are redeemable with our common stock (see Note 16). 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 16). 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 three and six months ended June 30, 2019 and 2018, the two-class method resulted in the most dilutive EPS calculation.

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. Actual results could differ from those estimates. The most significant and subjective estimate that we make is the projection of cash flows we expect to receive on our loans, investment securities and intangible assets, which has a significant impact on the amounts of interest income, credit losses (if any) and fair values that we record and/or disclose. In addition, the fair value of financial 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.

Recent Accounting Developments

On June 16, 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326) – Measurement of Credit Losses on Financial Instruments, which mandates use of an “expected loss” credit model for estimating future credit losses of certain financial instruments instead of the “incurred loss” credit model that current GAAP requires. The “expected loss” 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 in accordance with the current “incurred loss” methodology. This ASU is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2019. Though we have not completed our assessment of this ASU, we expect this ASU to result in our recognition of higher levels of allowances for loan losses. Our assessment of the estimated amount of such increases remains in process.

On January 26, 2017, the FASB issued ASU 2017-04, Goodwill and Other (Topic 350) – Simplifying the Test for Goodwill Impairment, which simplifies the method applied for measuring impairment in cases where goodwill is impaired. This ASU specifies that goodwill impairment will be 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. This ASU is effective for annual periods, and interim periods therein, beginning after December 15, 2019 and is applied prospectively. Early application is permitted. We do not expect the application of this ASU to materially impact the Company.

On August 28, 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) – Disclosure Framework, which adds new disclosure requirements and modifies or eliminates existing disclosure requirements of ASC 820. This ASU is effective for annual periods, and interim periods therein, beginning after December 15, 2019. Early application is permitted. We do not expect the application of this ASU to materially impact the Company, as it only affects fair value disclosures.

On October 31, 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810) – Targeted Improvements to Related Party Guidance for Variable Interest Entities, which requires reporting entities to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety for determining whether a decision-making fee is a variable interest. This ASU is effective for annual periods, and interim periods therein, beginning after December 15, 2019. Early application is permitted. We are in the process of assessing the impact this ASU will have on the Company, but do not expect it to be material.
