Description of Business
Description of Business	Note 1 — Description of Business Arbor Realty Trust, Inc. (“we,” “us,” or “our”) is a Maryland corporation formed in 2003. We operate through two business segments: our Structured Loan Origination and Investment Business ("Structured Business”) and our Agency Loan Origination and Servicing Business ("Agency Business”). Through our Structured Business, we invest in a diversified portfolio of structured finance assets in the multifamily and commercial real estate markets, primarily consisting of bridge and mezzanine loans, including junior participating interests in first mortgages, preferred and direct equity. We may also directly acquire real property and invest in real estate-related notes and certain mortgage-related securities. Through our Agency Business, we originate, sell and service a range of multifamily finance products through the Federal National Mortgage Association ("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac," and together with Fannie Mae, the government-sponsored enterprises, or the "GSEs"), the Government National Mortgage Association ("Ginnie Mae"), Federal Housing Authority ("FHA") and the U.S. Department of Housing and Urban Development (together with Ginnie Mae and FHA, "HUD") and conduit/commercial mortgage-backed securities ("CMBS") programs. We retain the servicing rights and asset management responsibilities on substantially all loans we originate and sell under the GSE and HUD programs. We are an approved Fannie Mae Delegated Underwriting and Servicing ("DUS") lender nationally, a Freddie Mac Multifamily Conventional Loan lender, seller/servicer, in New York, New Jersey and Connecticut, a Freddie Mac affordable, manufactured housing, senior housing and small balance loan ("SBL") lender, seller/servicer, nationally and a HUD MAP and LEAN senior housing/healthcare lender nationally. We have operated the Agency Business since July 2016 when we acquired it from Arbor Commercial Mortgage, LLC (“ACM” or our “Former Manager”). We were externally managed and advised by ACM and, effective May 31, 2017, terminated the existing management agreement with ACM to fully internalize our management team. Refer to our 2017 Annual Report for details of our acquisition of the Agency Business (the “Acquisition”) and termination of the management agreement. Substantially all of our operations are conducted through our operating partnership, Arbor Realty Limited Partnership (“ARLP”), for which we serve as the general partner, and ARLP’s subsidiaries. We are organized to qualify as a real estate investment trust (“REIT”) for U.S. federal income tax purposes. Certain of our assets that produce non-qualifying income, primarily within the Agency Business, are operated through taxable REIT subsidiaries (“TRS”), which is part of our TRS consolidated group (the “TRS Consolidated Group”) and is subject to U.S. federal, state and local income taxes. See Note 17 - Income Taxes for details.

Basis of Presentation and Significant Accounting Policies
Basis of Presentation and Significant Accounting Policies	Note 2 — Basis of Presentation and Significant Accounting Policies Basis of Presentation Our interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), for interim financial statements and the instructions to Form 10-Q. Accordingly, certain information and footnote disclosures normally included in the consolidated financial statements prepared under GAAP have been condensed or omitted. In our opinion, all adjustments considered necessary for a fair presentation of our financial position, results of operations and cash flows have been included and are of a normal and recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These financial statements should be read in conjunction with our financial statements and notes thereto included in our 2017 Annual Report. Reclassification Certain prior period amounts have been reclassified to conform to the current period presentation. See the following “Recently Adopted Accounting Pronouncements” section for the cash flows impact of the retrospective adoption of Accounting Standards Update (“ASU”) 2016-18, Statement of Cash Flows: Restricted Cash and ASU 2016-15, Statement of Cash Flows. Principles of Consolidation These consolidated financial statements include our financial statements and the financial statements of our wholly owned subsidiaries, partnerships and other joint ventures in which we own a controlling interest, including variable interest entities (“VIEs”) of which we are the primary beneficiary. Entities in which we have a significant influence are accounted for under the equity method. See Note 15 - Variable Interest Entities for information about our VIEs. All significant intercompany transactions and balances have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that could materially affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Significant Accounting Policies We describe our significant accounting policies in our 2017 Annual Report. There have been no significant changes in our significant accounting policies since December 31, 2017. Recently Adopted Accounting Pronouncements Description Adoption Date Effect on Financial Statements Since 2014, the Financial Accounting Standards Board ("FASB") has issued several amendments to its guidance on revenue recognition. The amended guidance, among other things, introduces a new framework for a single comprehensive model that can be used when accounting for revenue and supersedes most current revenue recognition guidance, including that which pertains to specific industries. The core principle states that an entity should recognize revenue to depict the transfer of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods and services. It also requires expanded quantitative and qualitative disclosures that will enable financial statement users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Most revenue associated with financial instruments, including interest and loan origination fees, along with gains and losses on investment securities, derivatives and sales of financial instruments are excluded from the scope of the guidance. First quarter of 2018 The adoption of this guidance did not have a material impact on our consolidated financial statements. This standard may impact the timing of gains on certain future sales of real estate. In November 2016, the FASB issued Accounting Standards Update ("ASU") 2016-18, Statement of Cash Flows: Restricted Cash. This ASU requires changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents to be shown in the statement of cash flows. Previous guidance required the change in cash and cash equivalents be shown on the statement of cash flows, with cash used to fund restricted cash and restricted cash equivalents shown as a component of operating, investing, or financing activities. Entities are now also required to reconcile the total of cash, cash equivalents, restricted cash, and restricted cash equivalents as presented in the statement of cash flows to the related captions in the balance sheet when these balances are presented separately in the balance sheet. First quarter of 2018 This guidance required retrospective adoption, therefore, we adjusted the cash flow statement for the comparable prior period. The following table shows the impact of the adoption of this guidance, as well as the adoption of ASU 2016-15 described below. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, which provides eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. First quarter of 2018 This guidance required retrospective adoption, therefore, we reclassified $0.5 million of net proceeds from insurance settlements from net cash provided by operating activities to net cash used in investing activities for the nine months ended September 30, 2017. We also chose the cummulative earnings approach for distributions received from equity method investees, which did not result in any changes in how we account for such distributions. The following table shows the impact of the adoption of ASU 2016-15 and ASU 2016-18. Nine Months Ended (in thousands) September 30, 2017 As previously reported under GAAP applicable at the time Cash and cash equivalents at beginning of period $ 138,645 Net decrease in cash and cash equivalents (53,894) Cash and cash equivalents at end of period 84,751 Net cash provided by operating activities: changes in operating assets and liabilities (6,252) Net cash used in investing activities (350,841) Net cash used in financing activities (90,954) As currently reported under ASU 2016-18 and ASU 2016-15 Cash, cash equivalents and restricted cash at beginning of period $ 167,960 Net increase in cash, cash equivalents and restricted cash 53,930 Cash, cash equivalents and restricted cash at end of period 221,890 Net cash (used in) provided by operating activities: changes in operating assets and liabilities (6,368) Net cash used in investing activities (350,348) Net cash provided by financing activities 16,840 In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall: Consensuses of the FASB Emerging Issues Task Force. This ASU requires that unconsolidated equity investments not accounted for under the equity method be recorded at fair value, with changes in fair value recorded through net income. The accounting principles that permitted available-for-sale classification with unrealized holding gains and losses recorded in other comprehensive income for equity securities will no longer be applicable. In addition, financial liabilities measured using the fair value option will need to present any change in fair value caused by a change in instrument-specific credit risk separately in other comprehensive income. First quarter of 2018 The adoption of this guidance did not have a material impact on our consolidated financial statements. In connection with the adoption of this ASU, we reclassified $0.2 million of unrealized gains on available-for-sale securities from accumulated other comprehensive income to accumulated deficit. Recently Issued Accounting Pronouncements The following table is not intended to represent all recently issued accounting pronouncements that are not yet effective and which have not yet been adopted by us. This table should be read in conjunction with the recently issued accounting pronouncements section included in our 2017 Annual Report. Description Effective Date Effect on Financial Statements In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with changes between hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. Early adoption is permitted upon issuance of the update. First quarter of 2020 We do not expect the adoption of this guidance to have a significant impact to our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU requires lessees to record most leases on their balance sheet through operating and finance lease liabilities and corresponding right-of-use assets, as well as adding additional footnote disclosures of key information about those arrangements. In July 2018, the FASB also issued ASU 2018-11, Leases (Topic 842) - Targeted Improvements, which provides transition releif on comparative period reporting through a cummulative-effect adjustment at the beginning of the period of adoption. First quarter of 2019 We are currently evaluating this ASU and expect the adoption to increase both our total assets and total liabilities by less than 1%. We do not currently expect the adoption to have an impact on our consolidated results of operations.

Certain loans and investments that require an additional rate of interest “Accrual Rate” to be paid at maturity are not included in the weighted average pay rate as shown in the table. (2) The “First Dollar Loan-to-Value (“LTV”) Ratio” is calculated by comparing the total of our senior most dollar and all senior lien positions within the capital stack to the fair value of the underlying collateral to determine the point at which we will absorb a total loss of our position. (3) The “Last Dollar LTV Ratio” is calculated by comparing the total of the carrying value of our loan and all senior lien positions within the capital stack to the fair value of the underlying collateral to determine the point at which we will initially absorb a loss. Concentration of Credit Risk We are subject to concentration risk in that, at September 30, 2018, the UPB related to 48 loans with five different borrowers represented 23% of total assets. At December 31, 2017, the UPB related to 42 loans with five different borrowers represented 24% of total assets. During both the nine months ended September 30, 2018 and the year ended December 31, 2017, no single loan or investment represented more than 10% of our total assets and no single investor group generated over 10% of our revenue. We assign a credit risk rating of pass, pass/watch, special mention, substandard or doubtful to each loan and investment, with a pass rating being the lowest risk and a doubtful rating being the highest risk. Each credit risk rating has benchmark guidelines that pertain to debt-service coverage ratios, LTV ratios, borrower strength, asset quality, and funded cash reserves. Other factors such as guarantees, market strength, and remaining loan term and borrower equity are also reviewed and factored into determining the credit risk rating assigned to each loan. This metric provides a helpful snapshot of portfolio quality and credit risk. All portfolio assets are subject to, at a minimum, a thorough quarterly financial evaluation in which historical operating performance and forward-looking projections are reviewed, however, we maintain a higher level of scrutiny and focus on loans that we consider “high risk” and that possess deteriorating credit quality. Generally speaking, given our typical loan profile, risk ratings of pass, pass/watch and special mention suggest that we expect the loan to make both principal and interest payments according to the contractual terms of the loan agreement, and is not considered impaired. A risk rating of substandard indicates we anticipate the loan may require a modification of some kind. A risk rating of doubtful indicates we expect the loan to underperform over its term, and there could be loss of interest and/or principal. Further, while the above are the primary guidelines used in determining a certain risk rating, subjective items such as borrower strength, market strength or asset quality may result in a rating that is higher or lower than might be indicated by any risk rating matrix. As a result of the loan review process, at September 30, 2018 and December 31, 2017, we identified eight loans and investments that we consider higher-risk loans that had a carrying value, before loan loss reserves, of $128.7 million and $126.5 million, respectively, and a weighted average last dollar LTV ratio of 92% and 93%, respectively.

Impaired Loans and Allowance for Loan Losses A summary of the changes in the allowance for loan losses is as follows (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Allowance at beginning of period $ 58,733 $ 81,256 $ 62,783 $ 83,712 Provision for loan losses 2,218 2,000 3,868 2,000 Recoveries of reserves — — (2,527) (2,456) Charge-offs — — (3,173) — Allowance at end of period $ 60,951 $ 83,256 $ 60,951 $ 83,256 During the three and nine months ended September 30, 2018, we determined that the fair value of the underlying collateral (land development project) securing six loans with a carrying value of $121.4 million was less than the net carrying value of the loans, which resulted in a provision for loan losses of $0.5 million and $2.2 million, respectively. In addition, we fully reserved a bridge loan and recorded a provision for loan loss of $1.7 million during the three and nine months ended September 30, 2018. During the nine months ended September 30, 2018, we received $31.6 million to settle a non-performing preferred equity investment in a hotel property with a UPB of $34.8 million and a net carrying value of $29.1 million, resulting in a reserve recovery of $2.5 million and a charge-off of $3.2 million. In addition, during the three and nine months ended September 30, 2018, we received payments and recorded reserve recoveries of $1.4 million and $2.3 million, respectively, related to previously written-off loans and investments. During the three and nine months ended September 30, 2017, we determined that the fair value of the underlying collateral securing a preferred equity investment with an aggregate carrying value of $34.8 million was less than the net carrying value of the investment, resulting in a $2.0 million provision for loan losses. In addition, during the nine months ended September 30, 2017, a fully reserved mezzanine loan with a UPB of $1.8 million paid off in full, which resulted in a $1.8 million reserve recovery, and we recorded a reserve recovery of $0.7 million on a multifamily bridge loan. The ratio of net recoveries to the average loans and investments outstanding was de minimus for the three months ended September 30, 2018 and 0.1% for all other periods presented. There were no loans for which the fair value of the collateral securing the loan was less than the carrying value of the loan for which we had not recorded a provision for loan loss as of September 30, 2018 and 2017. We have six loans with a carrying value totaling $121.4 million at September 30, 2018 that are collateralized by a land development project. These loans were scheduled to mature in September 2018 and were extended to September 2019. The loans do not carry a current pay rate of interest, but five of the loans with a carrying value totaling $112.0 million entitle us to a weighted average accrual rate of interest of 8.97%. In 2008, we suspended the recording of the accrual rate of interest on these loans, as they were impaired and we deemed the collection of this interest to be doubtful. At September 30, 2018 and December 31, 2017, we had cumulative allowances for loan losses of $51.2 million and $49.1 million, respectively, related to these loans. The loans are subject to certain risks associated with a development project including, but not limited to, availability of construction financing, increases in projected construction costs, demand for the development's outputs upon completion of the project, and litigation risk. Additionally, these loans were not classified as non-performing as the borrower is in compliance with all of the terms and conditions of the loans.

(2) Represents an average of the beginning and ending UPB of each asset class. At September 30, 2018, two loans with an aggregate net carrying value of $0.8 million, net of related loan loss reserves of $1.7 million, were classified as non-performing. At December 31, 2017, two loans with an aggregate net carrying value of $29.1 million, net of related loan loss reserves of $7.4 million, were classified as non-performing. Income from non-performing loans is generally recognized on a cash basis when it is received. Full income recognition will resume when the loan becomes contractually current and performance has recommenced.

There were no loan modifications, refinancing's and/or extensions during the nine months ended September 30, 2018 that were considered troubled debt restructurings. During the nine months ended September 30, 2017, there was a $34.8 million loan to a hotel property that was modified and considered a troubled debt restructuring as a result of a forbearance agreement entered into with the borrower in the second quarter of 2017. This loan was subsequently classified as non-performing. This loan was modified to increase the total recovery of the combined principal and interest. There were no other loans in which we considered the modifications to be troubled debt restructurings and no additional loans considered to be impaired as a result of our troubled debt restructuring analysis performed during the nine months ended September 30, 2018 and 2017. Given the transitional nature of some of our real estate loans, we may require funds to be placed into an interest reserve, based on contractual requirements, to cover debt service costs. At September 30, 2018, we had total interest reserves of $41.3 million on 98 loans with an aggregate UPB of $2.01 billion. At December 31, 2017, we had total interest reserves of $52.5 million on 81 loans with an aggregate UPB of $1.57 billion.

As part of the securitizations under the SBL program, we have the option to purchase the bottom tranche bond, generally referred to as the “B Piece,” that represents the bottom 10%, or highest risk, of the securitization. During the nine months ended September 30, 2018, we purchased two B Piece bonds with an initial face value of $31.2 million, at a discount, for $21.6 million. As of September 30, 2018, we retained 49%, or $72.2 million initial face value, of five B Piece bonds, which were purchased at a discount for $48.8 million, and sold the remaining 51% to a third party at par. These held-to-maturity securities are carried at cost, net of unamortized discounts, and are collateralized by a pool of multifamily mortgage loans, bear interest at an initial weighted average variable rate of 3.63% and have an estimated weighted average maturity of 5.7 years. The weighted average effective interest rate was 11.32% and 12.97% at September 30, 2018 and December 31, 2017, respectively, including the accretion of discount. Approximately $10.7 million is estimated to mature within one year, $30.6 million is estimated to mature after one year through five years, $20.0 million is estimated to mature after five years through ten years and $9.2 million is estimated to mature after ten years.

During the three and nine months ended September 30, 2018, we recorded income of $0.4 million and $1.2 million, respectively, and, during the three and nine months ended September 30, 2017, we recorded a loss of $1.3 million and $1.9 million, respectively, to (loss) income from equity affiliates in our consolidated statements of income related to our investment in this residential mortgage banking business. In addition, during the first quarter of 2018, we made a $2.4 million payment for our proportionate share of a litigation settlement related to this investment, which was distributed back to us by our equity affiliate.

(4) Represents restricted cash held for principal repayments as well as for reinvestment in the CLOs. Does not include restricted cash related to interest payments, delayed fundings and expenses. CLO X - In June 2018, we completed a collateralized securitization vehicle ("CLO X"), issuing seven tranches of CLO notes through two newly-formed wholly-owned subsidiaries totaling $494.2 million. Of the total CLO notes issued, $441.0 million were investment grade notes issued to third party investors and $53.2 million were below investment grade notes retained by us. As of the CLO closing date, the notes were secured by a portfolio of loan obligations with a face value of $501.9 million, consisting primarily of bridge loans that were contributed from our existing loan portfolio. The financing has a four-year replacement period that allows the principal proceeds and sale proceeds (if any) of the loan obligations to be reinvested in qualifying replacement loan obligations, subject to the satisfaction of certain conditions set forth in the indenture. Thereafter, the outstanding debt balance will be reduced as loans are repaid. Initially, the proceeds of the issuance of the securities also included $58.1 million for the purpose of acquiring additional loan obligations for a period of up to 120 days from the CLO closing date, which we subsequently utilized, resulting in the issuer owning loan obligations with a face value of $560.0 million, representing leverage of 79%. We retained a residual interest in the portfolio with a notional amount of $119.0 million, including the $53.2 million below investment grade notes. The notes had an initial weighted average interest rate of 1.45% plus one-month LIBOR and interest payments on the notes are payable monthly. CLO V - In June 2018, we completed the unwind of CLO V, redeeming $267.8 million of outstanding notes which were repaid primarily from the refinancing of the remaining assets within our existing financing facilities (including CLO X), as well as with cash held by CLO V, and expensed $1.3 million of deferred financing fees into interest expense on the consolidated statements of income. Luxembourg Debt Fund In November 2017, we formed a $100.0 million Luxembourg commercial real estate debt fund ("Debt Fund") and issued $70.0 million of floating rate notes to third party investors which bear an initial interest rate of 4.15% over LIBOR. The notes mature in 2025 and we retained a $30.0 million equity interest in the Debt Fund. The Debt Fund is a VIE for which we are the primary beneficiary and is consolidated in our financial statements. The Debt Fund is secured by a portfolio of loan obligations with a face value of $100.0 million, which includes first mortgage bridge loans, senior participation interests in first mortgage bridge loans, subordinate participation interest in first mortgage bridge loans and participation interests in mezzanine loans. The Debt Fund allows, for a period of three years, principal proceeds from portfolio assets to be reinvested in qualifying replacement assets, subject to certain conditions. Borrowings and the corresponding collateral under our Debt Fund are as follows ($ in thousands): Debt Collateral (3) Loans Cash Face Carrying Wtd. Avg.

Excludes restricted cash related to interest payments, delayed fundings and expenses. Senior Unsecured Notes In March 2018, we issued $100.0 million aggregate principal amount of 5.625% senior unsecured notes due in May 2023 (the "Initial Notes") in a private placement, and, in May 2018, we issued an additional $25.0 million (the "Reopened Notes" and, together with the Initial Notes, the "5.625% Notes,") which brought the aggregate outstanding principal amount to $125.0 million. The Reopened Notes are fully fungible with, and rank equally in right of payment with the Initial Notes. We received total proceeds of $122.3 million from the issuances, after deducting the underwriting discount and other offering expenses. We used the net proceeds from the Initial Notes to fully redeem our 7.375% senior unsecured notes due in 2021 (the “7.375% Notes") totaling $97.9 million and the net proceeds from the Reopened Notes to make investments and for general corporate purposes. The 5.625% Notes are unsecured and can be redeemed by us at any time prior to April 1, 2023, at a redemption price equal to 100% of the aggregate principal amount, plus a "make-whole" premium and accrued and unpaid interest. We have the right to redeem the 5.625% Notes on or after April 1, 2023, at a redemption price equal to 100% of the aggregate principal amount, plus accrued and unpaid interest. The interest is paid semiannually in May and November starting in November 2018. At September 30, 2018, the debt carrying value of the 5.625% Notes was $122.4 million, net of $2.6 million of deferred financing fees, and the weighted average note rate was 6.08%, including certain fees and costs. At December 31, 2017, the debt carrying value of our 7.375% Notes was $95.3 million, which was net of $2.6 million of deferred financing fees, and the weighted average note rate was 8.16%. Convertible Senior Unsecured Notes We issued $264.5 million in aggregate principal amount of 5.25% convertible senior notes (the "5.25% Convertible Notes”) through two separate private placement offerings during the three months ended September 30, 2018, which includes the exercised purchaser’s total over-allotment option of $34.5 million. The 5.25% Convertible Notes pay interest semiannually in arrears and are scheduled to mature in July 2021, unless earlier converted or repurchased by the holders pursuant to their terms. The initial conversion rates of the two offerings ($115.0 million issued on July 3, 2018 and $149.5 million issued on July 20, 2018) were 86.9943 shares and 77.8331 shares of common stock per $1,000 of principal, respectively, representing a conversion price of $11.50 per share and $12.85 per share of common stock, respectively. The initial conversion rates and conversion prices remain unchanged at September 30, 2018. We received proceeds totaling $256.1 million from the offerings of our 5.25% Convertible Notes, net of the underwriter’s discount and fees, which is being amortized through interest expense over the life of such notes. We used the net proceeds from the issuance primarily for the initial exchange of $127.6 million of our 5.375% convertible senior unsecured notes (the “5.375% Convertible Notes”) and $99.8 million of our 6.50% convertible senior unsecured notes (the “6.50% Convertible Notes”) for a combination of $219.8 million in cash (which includes accrued interest) and 6.8 million shares of our common stock. The remaining net proceeds were used for general corporate purposes. In the three months ended September 30, 2018, we recorded a loss on extinguishment of debt of $5.0 million in connection with these exchanges, which included an inducement charge of $1.1 million. At September 30, 2018, there were $16.2 million and $0.2 million aggregate principal amount remaining of our 5.375% Convertible Notes and 6.50% Convertible Notes, respectively. The initial conversion rates of the 5.375% Convertible Notes and 6.50% Convertible Notes were 107.7122 shares and 119.3033 shares, respectively, of common stock per $1,000 of principal, which represented a conversion price of $9.28 per share and $8.38 per share of common stock, respectively. At September 30, 2018, the 5.375% Convertible Notes and 6.50% Convertible Notes had conversion rates of 109.2211 shares and 123.2929 shares, respectively, of common stock per $1,000 of principal, which represented a conversion price of $9.16 per share and $8.11 per share of common stock, respectively. The 5.375% Convertible Notes and 6.50% Convertible Notes pay interest semiannually in arrears and have scheduled maturity dates in November 2020 and October 2019, respectively, unless earlier converted or repurchased by the holders pursuant to their terms. Our convertible senior unsecured notes are not redeemable by us prior to their maturities and are convertible into, at our election, cash, shares of our common stock or a combination of both, subject to the satisfaction of certain conditions and during specified periods. The conversion rates are subject to adjustment upon the occurrence of certain specified events and the holders may require us to repurchase all, or any portion, of their notes for cash equal to 100% of the principal amount, plus accrued and unpaid interest, if we undergo a fundamental change specified in the agreements. We intend to settle the principal balance of our convertible debt in cash and have not assumed share settlement of the principal balance for purposes of computing EPS. At the time of issuance, there is no precedent or policy that would indicate that we would settle the principal in shares or the conversion spread in cash. Accounting guidance requires that convertible debt instruments with cash settlement features, including partial cash settlement, account for the liability component and equity component (conversion feature) of the instrument separately. The initial value of the liability component reflects the present value of the discounted cash flows using the nonconvertible debt borrowing rate at the time of the issuance. The debt discount represents the difference between the proceeds received from the issuance and the initial carrying value of the liability component, which is accreted back to the notes principal amount through interest expense over the term of the notes, which was 2.72 years and 2.41 years at September 30, 2018 and December 31, 2017, respectively, on a weighted average basis. The UPB, unamortized discount and net carrying amount of the liability and equity components of our convertible notes were as follows (in thousands): Liability Equity Component Component Unamortized Debt Unamortized Deferred Net Carrying Net Carrying Period UPB Discount Financing Fees Value Value September 30, 2018 $ 280,816 $ 9,285 $ 7,878 $ 263,653 $ 9,436 December 31, 2017 $ 243,750 $ 5,742 $ 6,721 $ 231,287 $ 6,733 During the three months ended September 30, 2018, we incurred total aggregate interest expense on the notes of $5.0 million, of which $3.1 million, $1.0 million and $0.9 million related to the cash coupon, amortization of the deferred financing fees and of the debt discount, respectively. During the nine months ended September 30, 2018, we incurred total interest expense on the notes of $16.0 million, of which $9.9 million, $4.1 million and $2.0 million related to the cash coupon, amortization of the deferred financing fees and of the debt discount, respectively. During the three months ended September 30, 2017, we incurred total interest expense on the notes of $2.2 million, of which $1.6 million, $0.4 million and $0.2 million related to the cash coupon, amortization of the deferred financing fees and of the debt discount, respectively. During the nine months ended September 30, 2017, we incurred total interest expense on the notes of $6.6 million, of which $4.8 million, $1.1 million and $0.7 million related to the cash coupon, amortization of the deferred financing fees and of the debt discount, respectively. Including the amortization of the deferred financing fees and debt discount, our weighted average total cost of the notes is 7.45% per annum. Junior Subordinated Notes In the first quarter of 2017, we purchased, at a discount, $20.9 million of our junior subordinated notes with a carrying value of $19.8 million and recorded a gain on extinguishment of debt of $7.1 million. As a result, we settled our related equity investment and extinguished $21.5 million of notes. The carrying value of borrowings under our junior subordinated notes were $140.1 million and $139.6 million at September 30, 2018 and December 31, 2017, respectively, which is net of a deferred amount of $12.1 million and $12.5 million, respectively, (which is amortized into interest expense over the life of the notes) and deferred financing fees of $2.1 million and $2.2 million, respectively. These notes have maturities ranging from March 2034 through April 2037 and pay interest quarterly at a fixed or floating rate of interest based on LIBOR. The current weighted average note rate was 5.25% and 4.53% at September 30, 2018 and December 31, 2017, respectively. Including certain fees and costs, the weighted average note rate was 5.34% and 4.63% at September 30, 2018 and December 31, 2017, respectively. Related Party Financing In connection with the Acquisition, we entered into a five year $50.0 million preferred equity interest financing agreement with ACM to finance a portion of the aggregate purchase price. At December 31, 2017, the outstanding principal balance was $50.0 million. In January 2018, we paid $50.0 million in full satisfaction of this debt. During the nine months ended September 30, 2018, we recorded interest expense of $0.3 million and, during the three and nine months ended September 30, 2017, we recorded interest expense of $1.0 million and $2.9 million, respectively. Debt Covenants Credit Facilities and Repurchase Agreements. The credit facilities and repurchase agreements contain various financial covenants, including, but not limited to, minimum liquidity requirements, minimum net worth requirements, as well as certain other debt service coverage ratios, debt to equity ratios and minimum servicing portfolio tests. We were in compliance with all financial covenants and restrictions at September 30, 2018. CLOs. Our CLO vehicles contain interest coverage and asset overcollateralization covenants that must be met as of the waterfall distribution date for us to receive such payments. If we fail these covenants in any of our CLOs, all cash flows from the applicable CLO would be diverted to repay principal and interest on the outstanding CLO bonds and we would not receive any residual payments until that CLO regained compliance with such tests. Our CLOs were in compliance with all such covenants as of September 30, 2018, as well as on the most recent determination dates in October 2018. In the event of a breach of the CLO covenants that could not be cured in the near-term, we would be required to fund our non-CLO expenses, including employee costs, distributions required to maintain our REIT status, debt costs, and other expenses with (i) cash on hand, (ii) income from any CLO not in breach of a covenant test, (iii) income from real property and loan assets, (iv) sale of assets, or (v) accessing the equity or debt capital markets, if available. We have the right to cure covenant breaches which would resume normal residual payments to us by purchasing non-performing loans out of the CLOs. However, we may not have sufficient liquidity available to do so at such time. A summary of our CLO compliance tests as of the most recent determination dates in October 2018 is as follows: Cash Flow Triggers CLO VI CLO VII CLO VIII CLO IX CLO X Overcollateralization (1) Current 129.87 % 129.03 % 129.03 % 134.68 % 126.98 % Limit 128.87 % 128.03 % 128.03 % 133.68 % 125.98 % Pass / Fail Pass Pass Pass Pass Pass Interest Coverage (2) Current 208.68 % 212.40 % 268.75 % 276.05 % 236.32 % Limit 120.00 % 120.00 % 120.00 % 120.00 % 120.00 % Pass / Fail Pass Pass Pass Pass Pass (1) The overcollateralization ratio divides the total principal balance of all collateral in the CLO by the total principal balance of the bonds associated with the applicable ratio. To the extent an asset is considered a defaulted security, the asset’s principal balance for purposes of the overcollateralization test is the lesser of the asset’s market value or the principal balance of the defaulted asset multiplied by the asset’s recovery rate which is determined by the rating agencies. Rating downgrades of CLO collateral will generally not have a direct impact on the principal balance of a CLO asset for purposes of calculating the CLO overcollateralization test unless the rating downgrade is below a significantly low threshold (e.g. CCC-) as defined in each CLO vehicle. (2) The interest coverage ratio divides interest income by interest expense for the classes senior to those retained by us. Our CLO overcollateralization ratios as of the determination dates subsequent to each quarter are as follows: Determination (1) CLO VI CLO VII CLO VIII CLO IX CLO X October 2018 129.87 % 129.03 % 129.03 % 134.68 % 126.98 % July 2018 129.87 % 129.03 % 129.03 % 134.68 % 126.98 % April 2018 129.87 % 129.03 % 129.03 % 134.69 % — January 2018 129.87 % 129.03 % 129.03 % 134.68 % — October 2017 129.87 % 129.03 % 129.03 % — — (1) The table above represents the quarterly trend of our overcollateralization ratio, however, the CLO determination dates are monthly and we were in compliance with this test for all periods presented. The ratio fluctuates based on the performance of the underlying assets, transfers of assets into the CLOs prior to expiration of their respective replenishment dates, purchase or disposal of other investments, and loan payoffs. No payment due under the junior subordinated indentures may be paid if there is a default under any senior debt and the senior lender has sent notice to the trustee. The junior subordinated indentures are also cross-defaulted with each other.

The settled loss is often net of any previously advanced principal and interest payments in accordance with the DUS program, which are reflected as reductions to the proceeds needed to settle losses. At both September 30, 2018 and December 31, 2017, we had outstanding advances of $0.1 million, which were netted against the allowance for loss-sharing obligations. At September 30, 2018 and December 31, 2017, the maximum quantifiable liability associated with our guarantees under the Fannie Mae DUS agreement was $2.38 billion and $2.24 billion, respectively. The maximum quantifiable liability is not representative of the actual loss we would incur. We would be liable for this amount only if all of the loans we service for Fannie Mae, for which we retain some risk of loss, were to default and all of the collateral underlying these loans was determined to be without value at the time of settlement.

The commitments become effective when the borrower “rate locks” a specified interest rate within time frames established by us. All potential borrowers are evaluated for creditworthiness prior to the extension of the commitment. Market risk arises if interest rates move adversely between the time of the rate lock by the borrower and the sale date of the loan to an investor. To mitigate the effect of the interest rate risk inherent in providing rate lock commitments to borrowers, we enter into a forward sale commitment with the investor simultaneous with the rate lock commitment with the borrower. The forward sale contract locks in an interest rate and price for the sale of the loan. The terms of the contract with the investor and the rate lock with the borrower are matched in substantially all respects, with the objective of eliminating interest rate risk to the extent practical. Sale commitments with the investors have an expiration date that is longer than our related commitments to the borrower to allow, among other things, for the closing of the loan and processing of paperwork to deliver the loan into the sale commitment. These commitments meet the definition of a derivative and are recorded at fair value, including the effects of interest rate movements which are reflected as a component of other income, net in the consolidated statements of income. The estimated fair value of rate lock commitments also includes the fair value of the expected net cash flows associated with the servicing of the loan which is recorded as income from MSRs in the consolidated statements of income. During the three and nine months ended September 30, 2018, we recorded a net loss of $4.4 million and $2.3 million, respectively, from changes in the fair value of these derivatives in other income, net and $25.2 million and $62.8 million, respectively, of income from MSRs. During the three and nine months ended September 30, 2017, we recorded net gains of $0.2 million and net losses of $2.3 million, respectively, from changes in the fair value of these derivatives in other income, net and $18.9 million and $56.2 million, respectively, of income from MSRs. See Note 13 - Fair Value for details.

Hierarchical levels directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities are as follows: Level 1—Inputs are unadjusted and quoted prices exist in active markets for identical assets or liabilities, such as government, agency and equity securities. Level 2—Inputs (other than quoted prices included in Level 1) are observable for the asset or liability through correlation with market data. Level 2 inputs may include quoted market prices for a similar asset or liability, interest rates and credit risk. Examples include non-government securities, certain mortgage and asset-backed securities, certain corporate debt and certain derivative instruments. Level 3—Inputs reflect our best estimate of what market participants would use in pricing the asset or liability and are based on significant unobservable inputs that require a considerable amount of judgment and assumptions. Examples include certain mortgage and asset-backed securities, certain corporate debt and certain derivative instruments. Determining which category an asset or liability falls within the hierarchy requires significant judgment and we evaluate our hierarchy disclosures each quarter. The following is a description of the valuation techniques used to measure fair value and the general classification of these instruments pursuant to the fair value hierarchy. Loans and investments, net. Fair values of loans and investments that are not impaired are estimated using Level 3 inputs based on direct capitalization rate and discounted cash flow methodologies using discount rates, which, in our opinion, best reflect current market interest rates that would be offered for loans with similar characteristics and credit quality. Fair values of impaired loans and investments are estimated using Level 3 inputs that require significant judgments, which include assumptions regarding discount rates, capitalization rates, creditworthiness of major tenants, occupancy rates, availability of financing, exit plan and other factors. Loans held-for-sale, net. Consists of originated loans that are generally transferred or sold within 60 days of loan funding, and are valued using pricing models that incorporate observable inputs from current market assumptions or a hypothetical securitization model utilizing observable market data from recent securitization spreads and observable pricing of loans with similar characteristics (Level 2). Fair value includes the fair value allocated to the associated future MSRs and is calculated pursuant to the valuation techniques described below for capitalized mortgage servicing rights, net (Level 3). Capitalized mortgage servicing rights, net. Fair values are estimated using Level 3 inputs based on discounted future net cash flow methodology. The fair value of MSRs carried at amortized cost are estimated using a process that involves the use of independent third-party valuation experts, supported by commercially available discounted cash flow models and analysis of current market data. The key inputs used in estimating fair value include the contractually specified servicing fees, prepayment speed of the underlying loans, discount rate, annual per loan cost to service loans, delinquency rates, late charges and other economic factors. Securities held-to-maturity, net. Fair values are approximated using Level 3 inputs based on current market quotes received from financial sources that trade such securities and are based on prevailing market data and, in some cases, are derived from third party proprietary models based on well recognized financial principles and reasonable estimates about relevant future market conditions. Derivative financial instruments. The fair values of rate lock and forward sale commitments are estimated using valuation techniques, which include internally-developed models developed based on changes in the U.S. Treasury rate and other observable market data (Level 2). The fair value of rate lock commitments includes the fair value of the expected net cash flows associated with the servicing of the loans, see capitalized mortgage servicing rights, net above for details on the applicable valuation technique (Level 3). We also consider the impact of counterparty non-performance risk when measuring the fair value of these derivatives. Given the credit quality of our counterparties, the short duration of interest rate lock commitments and forward sale contracts, and our historical experience, the risk of nonperformance by our counterparties is not significant. Credit facilities and repurchase agreements. Fair values for credit facilities and repurchase agreements of the Structured Business are estimated at Level 3 using discounted cash flow methodology, using discount rates, which, in our opinion, best reflect current market interest rates for financing with similar characteristics and credit quality. The majority of our credit facilities and repurchase agreement for the Agency Business bear interest at rates that are similar to those available in the market currently and the fair values are estimated using Level 2 inputs. For these facilities, the fair values approximate their carrying values. Collateralized loan obligations, Debt Fund, junior subordinated notes and related party financing. Fair values are estimated at Level 3 based on broker quotations, representing the discounted expected future cash flows at a yield that reflects current market interest rates and credit spreads. Senior unsecured notes. Fair values are estimated at Level 1 when current market quotes received from active markets are available. If quotes from active markets are unavailable, then the fair values are estimated at Level 2 utilizing current market quotes received from inactive markets. Convertible senior unsecured notes, net. Fair values are estimated at Level 2 based on current market quotes received from inactive markets. We measure certain financial assets and financial liabilities at fair value on a recurring basis. The fair values of these financial assets and liabilities were determined using the following input levels as of September 30, 2018 (in thousands): Fair Value Measurements Using Fair Carrying Value Hierarchy Value Fair Value Level 1 Level 2 Level 3 Financial assets: Derivative financial instruments $ 926 $ 926 $ — $ 177 $ 749 Financial liabilities: Derivative financial instruments $ 3,406 $ 3,406 $ — $ 3,406 $ — We measure certain financial and non-financial assets at fair value on a nonrecurring basis.

(2) We recorded a $2.0 million impairment loss during the nine months ended September 30, 2018 on the office building we own. See Note 9 - Real Estate Owned for details. Loan impairment assessments. Loans held for investment are intended to be held to maturity and, accordingly, are carried at cost, net of unamortized loan origination costs and fees, loan purchase discounts, and net of the allowance for loan losses, when such loan or investment is deemed to be impaired. We consider a loan impaired when, based upon current information, it is probable that we will be unable to collect all amounts due for both principal and interest according to the contractual terms of the loan agreement. We evaluate our loans to determine if the value of the underlying collateral securing the impaired loan is less than the net carrying value of the loan, which may result in an allowance and corresponding charge to the provision for loan losses. These valuations require significant judgments, which include assumptions regarding capitalization and discount rates, revenue growth rates, creditworthiness of major tenants, occupancy rates, availability of financing, exit plan and other factors. The table above and below includes all impaired loans, regardless of the period in which the impairment was recognized. Long-lived assets. We review our real estate owned assets when events or circumstances change, indicating that the carrying amount of an asset may not be partially or fully recoverable. In the evaluation of a real estate owned asset for impairment, many factors are considered, including broker quotes, estimated current and expected operating cash flows from the asset during the projected holding period, costs necessary to extend the life or improve the asset, expected capitalization rates, projected stabilized net operating income, selling costs, and the ability to hold and dispose of the asset in the ordinary course of business. We first compare the undiscounted cash flows to be generated by the asset and broker quotes, if any, to the carrying value of such asset. If the undiscounted cash flows and/or broker quotes are less than the carrying value, we recognize an impairment loss by comparing the carrying value of the asset to its fair value.

Commitments and Contingencies	Note 14 — Commitments and Contingencies Debt Obligations. Our debt obligations have maturities of $565.9 million for the remainder of 2018, $356.2 million in 2019, $972.0 billion in 2020, $872.3 million in 2021, $244.2 million in 2022 and $401.4 million thereafter. Agency Business Commitments. Our Agency Business is subject to supervision by certain regulatory agencies. Among other things, these agencies require us to meet certain minimum net worth, operational liquidity and restricted liquidity collateral requirements, and compliance with reporting requirements. Our adjusted net worth and liquidity required by the agencies for all periods presented exceeded these requirements. As of September 30, 2018, we were required to maintain at least $12.9 million of liquid assets in one of our subsidiaries to meet our operational liquidity requirements for Fannie Mae and we had operational liquidity in excess of this requirement. We are generally required to share the risk of any losses associated with loans sold under the Fannie Mae DUS program and are required to secure this obligation by assigning restricted cash balances and/or a letter of credit to Fannie Mae. The amount of collateral required by Fannie Mae is a formulaic calculation at the loan level by a Fannie Mae assigned tier which considers the loan balance, risk level of the loan, age of the loan and level of risk-sharing. Fannie Mae requires restricted liquidity for Tier 2 loans of 75 basis points, 15 basis points for Tier 3 loans and 5 basis points for Tier 4 loans, which is funded over a 48-month period that begins upon delivery of the loan to Fannie Mae. A significant portion of our Fannie Mae DUS serviced loans for which we have risk sharing are Tier 2 loans. As of September 30, 2018, we met the restricted liquidity requirement with a $44.0 million letter of credit. As of September 30, 2018, reserve requirements for the Fannie Mae DUS loan portfolio will require us to fund $29.7 million in additional restricted liquidity over the next 48 months, assuming no further principal paydowns, prepayments, or defaults within our at-risk portfolio. Fannie Mae periodically reassesses these collateral requirements and may make changes to these requirements in the future. We generate sufficient cash flow from our operations to meet these capital standards and do not expect any changes to have a material impact on our future operations; however, future changes to collateral requirements may adversely impact our available cash. We are subject to various capital requirements in connection with seller/servicer agreements that we have entered into with secondary market investors. Failure to maintain minimum capital requirements could result in our inability to originate and service loans for the respective investor and, therefore, could have a direct material effect on our consolidated financial statements. As of September 30, 2018, we met all of Fannie Mae’s quarterly capital requirements and our Fannie Mae adjusted net worth was in excess of the required net worth. We are not subject to capital requirements on a quarterly basis for Ginnie Mae or FHA, as such requirements for these investors are only required on an annual basis. As an approved designated seller/servicer under Freddie Mac's SBL program, we are required to post collateral to ensure that we are able to meet certain purchase and loss obligations required by this program. Under the SBL program, we are required to post collateral equal to $5.0 million, which is satisfied with a $5.0 million letter of credit. We enter into contractual commitments with borrowers providing rate lock commitments while simultaneously entering into forward sale commitments with investors. These commitments are outstanding for short periods of time (generally less than 60 days) and are described in Note 12-Derivative Financial Instruments and Note 13-Fair Value. Unfunded Commitments. In accordance with certain structured loans and investments, we have outstanding unfunded commitments of $68.6 million as of September 30, 2018 that we are obligated to fund as borrowers meet certain requirements. Specific requirements include, but are not limited to, property renovations, building construction and conversions based on criteria met by the borrower in accordance with the loan agreements. Litigation. We are currently neither subject to any material litigation nor, to the best of our knowledge, threatened by any material litigation other than the following: In June 2011, three related lawsuits were filed by the Extended Stay Litigation Trust (the “Trust”), a post-bankruptcy litigation trust alleged to have standing to pursue claims that previously had been held by Extended Stay, Inc. and the Homestead Village L.L.C. family of companies (together “ESI”) (formerly Chapter 11 debtors, together the "Debtors") that have emerged from bankruptcy. Two of the lawsuits were filed in the U.S. Bankruptcy Court for the Southern District of New York, and the third in the Supreme Court of the State of New York, New York County. There were 73 defendants in the three lawsuits, including 55 corporate and partnership entities and 18 individuals. A subsidiary of ours and certain other entities that are affiliates of ours are included as defendants. The New York State Court action has been removed to the Bankruptcy Court. Our affiliates filed a motion to dismiss the three lawsuits. The lawsuits all allege, as a factual basis and background certain facts surrounding the June 2007 leveraged buyout of ESI from affiliates of Blackstone Capital. Our subsidiary, Arbor ESH II, LLC, had a $115.0 million investment in the Series A1 Preferred Units of a holding company of Extended Stay, Inc. The New York State Court action and one of the two federal court actions name as defendants, Arbor ESH II, LLC, ACM and ABT-ESI LLC, an entity in which we have a membership interest, among the broad group of defendants. These two actions were commenced by substantially identical complaints. The defendants are alleged in these complaints, among other things, to have breached fiduciary and contractual duties by causing or allowing the Debtors to pay illegal dividends or other improper distributions of value at a time when the Debtors were insolvent. These two complaints also allege that the defendants aided and abetted, induced, or participated in breaches of fiduciary duty, waste, and unjust enrichment (“Fiduciary Duty Claims”) and name a director of ours, and a former general counsel of ACM, each of whom had served on the Board of Directors of ESI for a period of time. We are defending these two defendants and paying the costs of such defense. On the basis of the foregoing allegations, the Trust has asserted claims under a number of common law theories, seeking the return of assets transferred by the Debtors prior to the Debtors' bankruptcy filing. In the third action, filed in Bankruptcy Court, the same plaintiff, the Trust, has named ACM and ABT-ESI LLC, together with a number of other defendants and asserts claims, including constructive and fraudulent conveyance claims under state and federal statutes, as well as a claim under the Federal Debt Collection Procedure Act. In June 2013, the Trust filed a motion to amend the lawsuits, to, among other things, (i) consolidate the lawsuits into one lawsuit, (ii) remove 47 defendants, none of whom are related to us, from the lawsuits so that there are 26 remaining defendants, including 16 corporate and partnership entities and 10 individuals, and (iii) reduce the counts within the lawsuits from over 100 down to 17. The remaining counts in the amended complaint against our affiliates are principally state law claims for breach of fiduciary duties, waste, unlawful dividends and unjust enrichment, and claims under the Bankruptcy Code for avoidance and recovery actions, among others. The bankruptcy court granted the motion and the amended complaint has been filed. The amended complaint seeks approximately $139.0 million in the aggregate, plus interest from the date of the alleged unlawful transfers, from director designees, portions of which are also sought from our affiliates as well as from unaffiliated defendants. We have moved to dismiss the referenced actions and intend to vigorously defend against the claims asserted therein. During a status conference held in March 2014, the Court heard oral argument on the motion to dismiss and adjourned the case pending a ruling. Subsequent to that hearing, a new judge was assigned to the case and, in November 2016, the new judge entered an order directing the parties to file supplemental briefs addressing new cases decided since the last round of briefing. Oral arguments regarding the motion to dismiss were heard at a hearing held in January 2017. The Court reserved decision at that hearing. We have not made a loss accrual for this litigation because we believe that it is not probable that a loss has been incurred and an amount cannot be reasonably estimated. Litigation Settlement . In July 2018, we received net proceeds of $10.2 million from the settlement of a litigation related to a prior investment, which was recognized as a gain in the three months ended September 30, 2018. Due to Borrowers. Due to borrowers represents borrowers’ funds held by us to fund certain expenditures or to be released at our discretion upon the occurrence of certain pre-specified events, and to serve as additional collateral for borrowers’ loans. While retained, these balances earn interest in accordance with the specific loan terms they are associated with.

Variable Interest Entities
Variable Interest Entities	Note 15 — Variable Interest Entities Our involvement with VIEs primarily affects our financial performance and cash flows through amounts recorded in interest income, interest expense, provision for loan losses and through activity associated with our derivative instruments. Consolidated VIEs. We have determined that our operating partnership, ARLP, and our CLO and Debt Fund entities, which we consolidate, are VIEs. ARLP is already consolidated in our financial statements, therefore, the identification of this entity as a VIE had no impact on our consolidated financial statements. Our CLO and Debt Fund consolidated entities invest in real estate and real estate-related securities and are financed by the issuance of debt securities. We, or one of our affiliates, are named collateral manager, servicer, and special servicer for all collateral assets held in CLOs, which we believe gives us the power to direct the most significant economic activities of those entities. We also have exposure to losses to the extent of our equity interests and also have rights to waterfall payments in excess of required payments to bond investors. As a result of consolidation, equity interests have been eliminated, and the consolidated balance sheets reflect both the assets held and debt issued by the CLOs and Debt Fund to third parties. Our operating results and cash flows include the gross amounts related to CLO and Debt Fund assets and liabilities as opposed to our net economic interests in those entities. The assets and liabilities related to these consolidated CLOs and Debt Fund are as follows (in thousands): September 30, 2018 December 31, 2017 Assets: Restricted cash $ 201,986 $ 138,736 Loans and investments, net 1,885,104 1,836,744 Due from related party 95,045 — Other assets 15,408 14,011 Total assets $ 2,197,543 $ 1,989,491 Liabilities: Collateralized loan obligations $ 1,592,089 $ 1,418,422 Debt fund 68,099 68,084 Other liabilities 3,013 2,046 Total liabilities $ 1,663,201 $ 1,488,552 Assets held by the CLOs and Debt Fund are restricted and can only be used to settle obligations of the CLOs and Debt Fund, respectively. The liabilities of the CLOs and Debt Fund are non-recourse to us and can only be satisfied from each respective asset pool. See Note 10—Debt Obligations for details. We are not obligated to provide, have not provided, and do not intend to provide financial support to any of the consolidated CLOs or Debt Fund. Unconsolidated VIEs. We determined that we are not the primary beneficiary of 23 VIEs in which we have a variable interest as of September 30, 2018 because we do not have the ability to direct the activities of the VIEs that most significantly impact each entity’s economic performance. The following is a summary of our variable interests in identified VIEs, of which we are not the primary beneficiary, as of September 30, 2018 (in thousands): Type Carrying Amount (1) Loans $ 287,166 B Piece bonds 50,520 Agency interest only strips 3,512 Total $ 341,198 (1) Represents the carrying amount of loans and investments before reserves. At September 30, 2018, $130.2 million of loans to VIEs had corresponding loan loss reserves of $59.3 million. See Note 3 - Loans and Investments for details. In addition, the maximum loss exposure as of September 30, 2018 would not exceed the carrying amount of our investment. These unconsolidated VIEs have exposure to real estate debt of approximately $3.01 billion at September 30, 2018.

Equity	Note 16 — Equity Preferred Stock. The Series A and B preferred stock became redeemable by us in February 2018 and May 2018, respectively. The Series C preferred stock may not be redeemed by us before February 2019. Common Stock.

In May 2018, we completed a public offering in which we sold 5,500,000 shares of our common stock for $8.72 per share, and received net proceeds of $47.8 million after deducting the underwriter’s discount and other offering expenses. The proceeds were used to make investments and for general corporate purposes. We have an “At-The-Market” equity offering sales agreement with JMP Securities LLC (“JMP,”) which entitles us to issue and sell up to 7,500,000 shares of our common stock through JMP. Sales of the shares are made by means of ordinary brokers’ transactions or otherwise at market prices prevailing at the time of sale, or at negotiated prices. During the nine months ended September 30, 2018, we sold 952,700 shares for net proceeds of $8.1 million. As of September 30, 2018, we had approximately 6,500,000 shares available under this agreement. In June 2018, we filed, and the SEC declared effective, a new shelf registration statement for $500.0 million of debt securities, common stock, preferred stock, depositary shares and warrants. Noncontrolling Interest. Noncontrolling interest relates to the operating partnership units (“OP Units”) issued to satisfy a portion of the Acquisition purchase price. Upon the closing of the Acquisition in 2016, we issued 21,230,769 OP Units. The value of these OP Units at the Acquisition date was $154.8 million. Each of these OP Units are paired with one share of our special voting preferred shares having a par value of $0.01 per share and is entitled to one vote each on any matter submitted for stockholder approval. In August 2018, ACM distributed 577,185 OP Units and special voting preferred shares to two of its partners in consideration for their respective membership interests, which were redeemed by us for cash totaling $6.8 million. At September 30, 2018, there were 20,653,584 OP Units outstanding, which represents approximately 21.4% of the voting power of our outstanding stock. The OP Units are entitled to receive distributions if and when our Board of Directors authorizes and declares common stock distributions. The OP Units are also redeemable for cash, or at our option, for shares of our common stock on a one-for-one basis. Distributions. Dividends declared (on a per share basis) during the nine months ended September 30, 2018 were as follows: Common Stock Preferred Stock Dividend (1) Declaration Date Dividend Declaration Date Series A Series B Series C February 21, 2018 $ 0.21 February 2, 2018 $ 0.515625 $ 0.484375 $ 0.53125 May 2, 2018 $ 0.25 May 2, 2018 $ 0.515625 $ 0.484375 $ 0.53125 August 1, 2018 $ August 1, 2018 $ $ $ (1) The dividend declared on August 1, 2018 was for June 1, 2018 through August 31, 2018, the dividend declared on May 2, 2018 was for March 1, 2018 through May 31, 2018 and the dividend declared on February 2, 2018 was for December 1, 2017 through February 28, 2018.

These amounts reflect dividends from September 1, 2018 through November 30, 2018 and are payable on November 30, 2018 to preferred stockholders of record on November 15, 2018. Deferred Compensation . In August 2018, we issued our chief executive officer 294,985 shares of performance-based restricted stock under his 2017 annual incentive agreement as a result of the Company meeting its goals related to the integration of the Acquisition. The award had a grant date fair value of $3.4 million and we recorded $0.2 million to employee compensation and benefits in our consolidated statements of income. In March 2018, we issued 265,444 shares of restricted common stock under the 2017 Amended Omnibus Stock Incentive Plan (the “2017 Plan”) to certain employees of ours with a total grant date fair value of $2.3 million and recorded $0.8 million to employee compensation and benefits in our consolidated statements of income. One third of the shares vested as of the grant date, one third will vest in March 2019, and the remaining third will vest in March 2020. In March 2018, we also issued 58,620 shares of fully vested common stock to the independent members of the Board of Directors under the 2017 Plan and recorded $0.5 million to selling and administrative expense in our consolidated statements of income. During the first quarter of 2018, we issued 63,584 shares of restricted common stock to our chief executive officer under his 2017 annual incentive agreement with a grant date fair value of $0.6 million and recorded $0.1 million to employee compensation and benefits in our consolidated statements of income. One quarter of the shares vested as of the grant date and one quarter will vest on each of the first, second and third anniversaries of the grant date. Our chief executive officer was also granted up to 381,503 performance-based restricted stock units that vest at the end of a four-year performance period based on our achievement of certain total stockholder return objectives. The restricted stock units had a grant date fair value of $0.8 million and we recorded less than $0.1 million to employee compensation and benefits in our consolidated statements of income. Earnings Per Share (“EPS”). Basic EPS is calculated by dividing net income attributable to common stockholders by the weighted average number of shares of common stock outstanding during each period inclusive of unvested restricted stock with full dividend participation rights. Diluted EPS is calculated by dividing net income by the weighted average number of shares of common stock outstanding plus the additional dilutive effect of common stock equivalents during each period using the treasury stock method. Our common stock equivalents include the weighted average dilutive effect of performance-based restricted stock units granted to our chief executive officer, OP Units and convertible senior unsecured notes. The following tables reconcile the numerator and denominator of our basic and diluted EPS computations ($ in thousands, except share and per share data): Three Months Ended September 30, 2018 2017 Basic Diluted Basic Diluted Net income attributable to common stockholders (1) $ 27,737 $ 27,737 $ 16,421 $ 16,421 Net income attributable to noncontrolling interest (2) — 7,799 — 5,662 Net income attributable to common stockholders and noncontrolling interest $ 27,737 $ 35,536 $ 16,421 $ 22,083 Weighted average shares outstanding 74,802,582 74,802,582 61,582,796 61,582,796 Dilutive effect of OP Units (2) — 21,023,735 — 21,230,769 Dilutive effect of restricted stock units (3) — 1,559,217 — 1,104,552 Dilutive effect of convertible notes (4) — 1,050,430 — — Weighted average shares outstanding Net income per common share (1) $ 0.37 $ 0.36 $ 0.27 $ 0.26 Nine Months Ended September 30, 2018 2017 Net income attributable to common stockholders (1) $ 71,093 $ 71,093 $ 43,964 $ 43,964 Net income attributable to noncontrolling interest (2) — 22,347 — 16,597 Net income attributable to common stockholders and noncontrolling interest $ 71,093 $ 93,440 $ 43,964 $ 60,561 Weighted average shares outstanding 67,490,132 67,490,132 56,602,504 56,602,504 Dilutive effect of OP Units (2) — 21,160,999 — 21,230,769 Dilutive effect of restricted stock units (3) — 1,441,264 — 1,077,178 Dilutive effect of convertible notes (4) — 1,041,212 — 32,468 Weighted average shares outstanding 67,490,132 91,133,607 56,602,504 78,942,919 Net income per common share (1) $ 1.05 $ 1.03 $ 0.78 $ 0.77 (1) Net of preferred stock dividends.

(3) Mr. Kaufman is granted restricted stock units annually, which vest at the end of a four-year performance period based upon our achievement of total stockholder return objectives. (4) The convertible senior unsecured notes impact diluted earnings per share if the average price of our common stock exceeds the conversion price, as calculated in accordance with the terms of the indenture.

Income Taxes
Income Taxes	Note 17 — Income Taxes As a REIT, we are generally not subject to U.S. federal income tax to the extent of our distributions to stockholders and as long as certain asset, income, distribution, ownership and administrative tests are met. To maintain our qualification as a REIT, we must annually distribute at least 90% of our REIT taxable income to our stockholders and meet certain other requirements. We may also be subject to certain state, local and franchise taxes. Under certain circumstances, federal income and excise taxes may be due on our undistributed taxable income. If we were to fail to meet these requirements, we would be subject to U.S. federal income tax, which could have a material adverse impact on our results of operations and amounts available for distributions to our stockholders. We believe that all of the criteria to maintain our REIT qualification have been met for the applicable periods, but there can be no assurance that these criteria will continue to be met in subsequent periods. The Agency Business is operated through our TRS Consolidated Group and is subject to U.S. federal, state and local income taxes. In general, our TRS entities may hold assets that the REIT cannot hold directly and may engage in real estate or non-real estate-related business. The Tax Cuts and Jobs Act (“Tax Reform”) was signed into law on December 22, 2017. Among numerous provisions included in the new tax law was the reduction of the corporate federal income tax rate from 35% to 21%. Our provision for income taxes in the nine months ended September 30, 2018 reflects the newly enacted corporate federal income tax rate of 21%. The final impact of the Tax Reform may differ due to, and among other things, changes in interpretations, assumptions made by us, the issuance of additional guidance and actions we may take as a result of the Tax Reform. In the three and nine months ended September 30, 2018, we recorded a tax provision of $5.4 million and $1.1 million, respectively. In the three and nine months ended September 30, 2017, we recorded a tax provision of $6.7 million and $16.2 million, respectively. The provision for income taxes recorded in the three months ended September 30, 2018 consisted of a current tax provision of $6.7 million and a deferred tax benefit of $1.3 million. The tax provision recorded in the nine months ended September 30, 2018 consisted of a current tax provision of $15.6 million and a deferred tax benefit of $14.5 million. The deferred tax benefit recorded in the nine months ended September 30, 2018 was due primarily to our payoff in January 2018 of the $50.0 million preferred equity interest entered into with ACM to finance a portion of the Acquisition purchase price. When we entered into the Acquisition, we established a deferred tax liability in connection with the $50.0 million preferred equity interest. Upon payoff in January 2018, the deferred tax liability was written off. See Note 10 - Debt Obligations for details. The provision for income taxes recorded in the three months ended September 30, 2017 consisted of a current tax provision of $7.6 million and a deferred tax benefit of $0.9 million. The provision for income taxes recorded in the nine months ended September 30, 2017 consisted of a current tax provision of $16.2 million. Current and deferred taxes are primarily recorded on the portion of earnings (losses) recognized by us with respect to our interest in the TRS’s. Deferred income tax assets and liabilities are calculated based on temporary differences between our U.S. GAAP consolidated financial statements and the federal, state, local tax basis of assets and liabilities as of the consolidated balance sheets.

Agreements and Transactions with Related Parties	Note 18 — Agreements and Transactions with Related Parties Management Agreement . Prior to May 31, 2017, we had a management agreement with ACM, pursuant to which ACM provided us with a variety of professional and advisory services vital to our operations, including underwriting, accounting and treasury, compliance, marketing, information technology and human resources. Pursuant to the terms of the management agreement, we reimbursed ACM for its actual costs incurred in connection with managing our business through a base management fee, and, under certain circumstances, an annual incentive fee. In May 2017, we terminated the existing management agreement. We incurred base management fees of $6.7 million in the nine months ended September 30, 2017. We have a shared services agreement with ACM where we provide limited support services to ACM and they reimburse us for the costs of performing such services.

Due to related party was $0.5 million at September 30, 2018 and consisted of loan payoffs, holdbacks and escrows to be remitted to our affiliated servicing operations related to real estate transactions. In August 2018, we originated a $17.7 million bridge loan to an entity owned, in part, by an immediate family member of our chief executive officer, who owns a 10.8% interest in the borrowing entity. The loan was used to purchase several undeveloped parcels of land. The loan has a fixed interest rate of 10% and matures in May 2019. Interest income recorded from this loan totaled $0.3 million for both the three and nine months ended September 30, 2018.

The loan has an interest rate of LIBOR plus 5.0%, with a LIBOR floor of 1.13%, and matures in June 2020. Interest income recorded from this loan totaled $0.6 million and $1.7 million for the three and nine months ended September 30, 2018, respectively. In the fourth quarter of 2017, we originated two bridge loans totaling $28.0 million on two multifamily properties owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owns 45% of the borrowing entity. The loans have an interest rate of LIBOR plus 5.25% with LIBOR floors ranging from 1.24% to 1.54% and mature in the fourth quarter of 2020. Interest income recorded from these loans totaled $0.5 million and $1.6 million for the three and nine months ended September 30, 2018, respectively. In July 2017, we originated a $36.0 million bridge loan on a multifamily property owned in part by a consortium of investors. The consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) own a 95% interest in the borrowing entity. The loan had an interest rate of LIBOR plus 4.5% with a LIBOR floor of 1% and was scheduled to mature in July 2020. This loan was repaid in full in August 2018. Interest income recorded from this loan totaled $0.7 million and $1.9 million for the three and nine months ended September 30, 2018, respectively, and $0.4 million for both the three and nine months ended September 30, 2017. In May 2017, we originated a $46.9 million Fannie Mae loan on a multifamily property owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers) which owns a 21.4% interest in the borrowing entity. We carry a maximum loss-sharing obligation with Fannie Mae on this loan of up to 5% of the original UPB. Servicing revenue recorded from this loan was less than $0.1 million and $0.1 million for the three and nine months ended September 30, 2018, respectively, and less than $0.1 million for both the three and nine months ended September 30, 2017. In March 2017, a consortium of investors (which includes, among other unaffiliated investors, our chief executive officer and ACM) invested $2.0 million for a 26.1% ownership interest in two portfolios of multifamily properties which has two bridge loans totaling $14.8 million originated by us in 2016. The loans had an interest rate of LIBOR plus 5.25% with a LIBOR floor of 0.5% and were scheduled to mature in November 2018. One of the loans was repaid in full in the fourth quarter of 2017 and the remaining loan paid off in June 2018. Interest income recorded from these loans totaled $0.3 million for the nine months ended September 30, 2018 and $0.3 million and $0.8 million for the three and nine months ended September 30, 2017, respectively. In January 2017, we modified a $5.0 million preferred equity investment, subsequently increasing our balance to $15.0 million, with a commitment to fund an additional $5.0 million. This investment had a fixed interest rate of 11% that was scheduled to mature in January 2020, however, the principal was repaid in full in the fourth quarter of 2017. We also entered into an agreement with a consortium of investors (which include, among other unaffiliated investors, certain of our officers and our chief executive officer) which admitted them as a member to fund the remaining $5.0 million preferred equity investment, which was generally subordinate to our investment. Interest income recorded from our investment totaled $0.2 million and $0.5 million in the three and nine months ended September 30, 2017, respectively. In January 2017, Ginkgo Investment Company LLC (“Ginkgo”), of which one of our directors is a 33% managing member, purchased a multifamily apartment complex which assumed an existing $8.3 million Fannie Mae loan that we service. Ginkgo subsequently sold the majority of its interest in this property and owned a 3.6% interest at September 30, 2018. We carry a maximum loss-sharing obligation with Fannie Mae on this loan of up to 20% of the original UPB. Upon the sale, we received a 1% loan assumption fee which was governed by existing loan agreements that were in place when the loan was originated in 2015, prior to such purchase. Servicing revenue recorded from this loan was less than $0.1 million for all periods presented. In 2016, we originated $48.0 million of bridge loans on six multifamily properties owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owns interests ranging from 10.5% to 12.0% in the borrowing entities. The loans have an interest rate of LIBOR plus 4.5% with a LIBOR floor of 0.25% and mature in September 2019. In August 2017, a $6.8 million loan on one property paid off in full and in May 2018 three additional loans totaling $23.2 million paid off in full. Interest income recorded from these loans totaled $0.3 million and $1.6 million for the three and nine months ended September 30, 2018, respectively, and $0.7 million and $2.1 million for the three and nine months ended September 30, 2017, respectively. In 2016, we originated a $12.7 million bridge loan and a $5.2 million preferred equity investment on two multifamily properties owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owns a 50% interest in the borrowing entity. The loan has an interest rate of LIBOR plus 4.5% with a LIBOR floor of 0.25% and matures in January 2019. The preferred equity investment has a fixed interest rate of 10% and a maturity extended to November 2018. Interest income recorded from these loans totaled $0.4 million and $1.0 million for the three and nine months ended September 30, 2018, respectively, and $0.3 million and $0.9 million for the three and nine months ended September 30, 2017, respectively. In 2016, we originated a $19.0 million bridge loan on a multifamily property owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owns a 7.5% interest in the borrowing entity. The loan had an interest rate of LIBOR plus 4.5% with a LIBOR floor of 0.25% and was scheduled to mature in January 2019. In January 2018, this loan paid off in full. Interest income recorded from this loan totaled $0.3 million for the nine months ended September 30, 2018 and $0.3 million and $0.8 million for the three and nine months ended September 30, 2017, respectively. In 2015, we originated a $7.1 million bridge loan on a multifamily property owned in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers and our chief executive officer) which owns a 7.5% interest in the borrowing entity. In August 2017, this loan paid off in full. The loan had an interest rate of LIBOR plus 4.5%, with a LIBOR floor of 0.25%. Interest income recorded from this loan totaled $0.1 million and $0.3 million for the three and nine months ended September 30, 2017, respectively. In 2015, we originated two bridge loans totaling $16.7 million secured by multifamily properties acquired by a third party investor. The properties were owned and were sold in part by a consortium of investors (which includes, among other unaffiliated investors, certain of our officers, our chief executive officer and certain other related parties). The loans have an interest rate of LIBOR plus 5% with a LIBOR floor of 0.25% and were scheduled to mature in October 2018. One of the loans paid off in full in September 2018 and the remaining loan was extended to November 2018. Interest income recorded from these loans totaled $0.3 million and $1.0 million for the three and nine months ended September 30, 2018, respectively, and $0.3 million and $0.8 million for the three and nine months ended September 30, 2017, respectively. In 2015, we originated a $3.0 million mezzanine loan on a multifamily property that had a $47.0 million first mortgage initially originated by ACM. The loan bore interest at a fixed rate of 12.5% and was scheduled to mature in April 2025. In January 2018, this loan paid off in full. Interest income recorded from this loan totaled $0.1 million for the nine months ended September 30, 2018 and $0.1 million and $0.3 million for the three and nine months ended September 30, 2017, respectively. In 2015, we invested $9.6 million for 50% of ACM's indirect interest in a joint venture with a third party that was formed to invest in a residential mortgage banking business. As a result of this transaction, we had an initial indirect interest of 22.5% in this entity. Since the initial investment, we invested an additional $16.1 million through this joint venture in non-qualified residential mortgages purchased from the mortgage banking business’s origination platform and we received cash distributions totaling $16.9 million (that were classified as returns of capital) as a result of the joint venture selling most of its mortgage assets (which $0.7 million was received in the nine months ended September 30, 2018). We recorded income from these investments of $0.4 million and $1.2 million in the three and nine months ended September 30, 2018, respectively, and a loss of $1.2 million and $1.8 million in the three and nine months ended September 30, 2017, respectively . In connection with a litigation settlement related to this investment, we provided a guaranty of up to 50% of any amounts payable in connection with the settlement. ACM has also provided us with a guaranty to pay up to 50% of any amounts we may pay under this guaranty. As of September 30, 2018, our maximum exposure under this guaranty totals $2.3 million. We have not accrued this amount as we do not believe that we will be required to make any nonrefundable payments under this guaranty. See Note 8-Investments in Equity Affiliates for details. In 2014, we invested $0.1 million for a 5% interest in a joint venture that owns two multifamily properties. The joint venture is comprised of a consortium of investors (which includes, among other unaffiliated investors, certain of our officers, our chief executive officer and certain other related parties) which owns a 95% interest. We had a $1.7 million bridge loan to the joint venture with an interest rate of 5.5% over LIBOR. The loan was repaid in full in the fourth quarter of 2017. Interest income recorded from this loan was less than $0.1 million and $0.1 million for the three and nine months ended September 30, 2017, respectively. In 2014, we originated a $30.4 million bridge loan for an office property owned in part by a consortium of investors (which includes, among other unaffiliated investors, our chief executive officer and his affiliates) which owns a 24% interest in the borrowing entity. The loan matured in August 2017 and was refinanced with a $43.2 million bridge loan that has an interest rate of 4% over LIBOR with a LIBOR floor of 1.23% and matures in August 2020. We also originated a $4.6 million mezzanine loan in 2016 to this entity that had a fixed interest rate of 12%, which was repaid in full at maturity in August 2017. In the fourth quarter of 2017, the consortium of investors sold their ownership interest in the borrowing entity. Interest income recorded from these loans totaled $0.8 million and $2.4 million for the three and nine months ended September 30, 2017, respectively. In 2014, ACM purchased a property subject to two loans originated by us, a first mortgage of $14.6 million and a second mortgage of $5.1 million, both with maturity dates of April 2016 and an interest rate of 4.8% over LIBOR. In 2016, the $5.1 million second mortgage was repaid in full and the $14.6 million first mortgage was extended to April 2018 and paid off at maturity. Interest income recorded from these loans totaled $0.2 million for the nine months ended September 30, 2018 and $0.2 million and $0.7 million for the three and nine months ended September 30, 2017, respectively. We, along with an executive officer of ours and a consortium of independent outside investors, hold equity investments in a portfolio of multifamily properties referred to as the Lexford Portfolio (“Lexford”), which is managed by an entity owned primarily by a consortium of affiliated investors, including our chief executive officer and an executive officer of ours. Based on the terms of the management contract, the management company is entitled to 4.75% of gross revenues of the underlying properties, along with the potential to share in the proceeds of a sale or restructuring of the debt. In June 2018, the owners of Lexford restructured part of its debt and we originated twelve bridge loans totaling $280.5 million, which were used to repay in full certain existing mortgage debt and to renovate 72 multifamily properties included in the portfolio. The loans which we originated in June 2018 have interest rates of 400 basis points over LIBOR and mature in June 2021 (with 2 one-year extension options). Interest income recorded from these loans totaled $4.4 million and $5.5 million in the three and nine months ended September 30, 2018, respectively. Further, as part of this June 2018 restructuring, $50.0 million in unsecured financing was provided by an unsecured lender to certain parent entities of the property owners. ACM owns slightly less than half of the unsecured lender entity and, therefore, provided slightly less than half of the unsecured lender financing. In addition, in connection with our equity investment, we received distributions totaling $0.7 million during both the three months ended September 30, 2018 and 2017 and $1.9 million and $2.0 million during the nine months ended September 30, 2018 and 2017, respectively, which were recorded as (loss) income from equity affiliates. Separate from loans which we originated in June 2018, we provide limited ("bad boy") guarantees for certain other debt controlled by Lexford. The bad boy guarantees may become a liability for us upon standard "bad" acts such as fraud or a material misrepresentation by Lexford or us. At September 30, 2018, this debt had an aggregate outstanding balance of $307.9 million and is scheduled to mature between 2019 and 2025. Several of our executives, including our chief financial officer, general counsel and our chairman, chief executive officer and president, hold similar positions for ACM. Our chief executive officer and his affiliated entities (“the Kaufman Entities”) together beneficially own approximately 75% of the outstanding membership interests of ACM and certain of our employees and directors also hold an ownership interest in ACM. Furthermore, one of our directors serves as the trustee and co-trustee of two of the Kaufman Entities that hold membership interests in ACM. Upon the closing of the Acquisition in 2016, we issued 21,230,769 OP Units, each paired with one share of our Special Voting Preferred Shares. In December 2017 and August 2018, ACM distributed 5,780,348 and 577,185 OP Units, respectively, to its members, which include the Kaufman Entities and certain of our officers and employees. At September 30, 2018, ACM holds 5,349,053 shares of our common stock and 14,873,236 OP Units, which represents 21.0% of the voting power of our outstanding stock. Our Board of Directors approved a resolution under our charter allowing our chief executive officer and ACM, (which our chief executive officer has a controlling equity interest in), to own more than the 5% ownership interest limit of our common stock as stated in our amended charter.

Basis of Presentation and Significant Accounting Policies
Basis of Presentation	Basis of Presentation Our interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), for interim financial statements and the instructions to Form 10-Q. Accordingly, certain information and footnote disclosures normally included in the consolidated financial statements prepared under GAAP have been condensed or omitted. In our opinion, all adjustments considered necessary for a fair presentation of our financial position, results of operations and cash flows have been included and are of a normal and recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These financial statements should be read in conjunction with our financial statements and notes thereto included in our 2017 Annual Report.
Reclassification	Reclassification Certain prior period amounts have been reclassified to conform to the current period presentation. See the following “Recently Adopted Accounting Pronouncements” section for the cash flows impact of the retrospective adoption of Accounting Standards Update (“ASU”) 2016-18, Statement of Cash Flows: Restricted Cash and ASU 2016-15, Statement of Cash Flows.
Principles of Consolidation	Principles of Consolidation These consolidated financial statements include our financial statements and the financial statements of our wholly owned subsidiaries, partnerships and other joint ventures in which we own a controlling interest, including variable interest entities (“VIEs”) of which we are the primary beneficiary. Entities in which we have a significant influence are accounted for under the equity method. See Note 15 - Variable Interest Entities for information about our VIEs. All significant intercompany transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that could materially affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements Description Adoption Date Effect on Financial Statements Since 2014, the Financial Accounting Standards Board ("FASB") has issued several amendments to its guidance on revenue recognition. The amended guidance, among other things, introduces a new framework for a single comprehensive model that can be used when accounting for revenue and supersedes most current revenue recognition guidance, including that which pertains to specific industries. The core principle states that an entity should recognize revenue to depict the transfer of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods and services. It also requires expanded quantitative and qualitative disclosures that will enable financial statement users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Most revenue associated with financial instruments, including interest and loan origination fees, along with gains and losses on investment securities, derivatives and sales of financial instruments are excluded from the scope of the guidance. First quarter of 2018 The adoption of this guidance did not have a material impact on our consolidated financial statements. This standard may impact the timing of gains on certain future sales of real estate. In November 2016, the FASB issued Accounting Standards Update ("ASU") 2016-18, Statement of Cash Flows: Restricted Cash. This ASU requires changes in the total of cash, cash equivalents, restricted cash, and restricted cash equivalents to be shown in the statement of cash flows. Previous guidance required the change in cash and cash equivalents be shown on the statement of cash flows, with cash used to fund restricted cash and restricted cash equivalents shown as a component of operating, investing, or financing activities. Entities are now also required to reconcile the total of cash, cash equivalents, restricted cash, and restricted cash equivalents as presented in the statement of cash flows to the related captions in the balance sheet when these balances are presented separately in the balance sheet. First quarter of 2018 This guidance required retrospective adoption, therefore, we adjusted the cash flow statement for the comparable prior period. The following table shows the impact of the adoption of this guidance, as well as the adoption of ASU 2016-15 described below. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, which provides eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. First quarter of 2018 This guidance required retrospective adoption, therefore, we reclassified $0.5 million of net proceeds from insurance settlements from net cash provided by operating activities to net cash used in investing activities for the nine months ended September 30, 2017. We also chose the cummulative earnings approach for distributions received from equity method investees, which did not result in any changes in how we account for such distributions. The following table shows the impact of the adoption of ASU 2016-15 and ASU 2016-18. Nine Months Ended (in thousands) September 30, 2017 As previously reported under GAAP applicable at the time Cash and cash equivalents at beginning of period $ 138,645 Net decrease in cash and cash equivalents (53,894) Cash and cash equivalents at end of period 84,751 Net cash provided by operating activities: changes in operating assets and liabilities (6,252) Net cash used in investing activities (350,841) Net cash used in financing activities (90,954) As currently reported under ASU 2016-18 and ASU 2016-15 Cash, cash equivalents and restricted cash at beginning of period $ 167,960 Net increase in cash, cash equivalents and restricted cash 53,930 Cash, cash equivalents and restricted cash at end of period 221,890 Net cash (used in) provided by operating activities: changes in operating assets and liabilities (6,368) Net cash used in investing activities (350,348) Net cash provided by financing activities 16,840 In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall: Consensuses of the FASB Emerging Issues Task Force. This ASU requires that unconsolidated equity investments not accounted for under the equity method be recorded at fair value, with changes in fair value recorded through net income. The accounting principles that permitted available-for-sale classification with unrealized holding gains and losses recorded in other comprehensive income for equity securities will no longer be applicable. In addition, financial liabilities measured using the fair value option will need to present any change in fair value caused by a change in instrument-specific credit risk separately in other comprehensive income. First quarter of 2018 The adoption of this guidance did not have a material impact on our consolidated financial statements. In connection with the adoption of this ASU, we reclassified $0.2 million of unrealized gains on available-for-sale securities from accumulated other comprehensive income to accumulated deficit. Recently Issued Accounting Pronouncements The following table is not intended to represent all recently issued accounting pronouncements that are not yet effective and which have not yet been adopted by us. This table should be read in conjunction with the recently issued accounting pronouncements section included in our 2017 Annual Report. Description Effective Date Effect on Financial Statements In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820) - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which makes a number of changes meant to add, modify or remove certain disclosure requirements associated with changes between hierarchy associated with Level 1, Level 2 and Level 3 fair value measurements. Early adoption is permitted upon issuance of the update. First quarter of 2020 We do not expect the adoption of this guidance to have a significant impact to our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU requires lessees to record most leases on their balance sheet through operating and finance lease liabilities and corresponding right-of-use assets, as well as adding additional footnote disclosures of key information about those arrangements. In July 2018, the FASB also issued ASU 2018-11, Leases (Topic 842) - Targeted Improvements, which provides transition releif on comparative period reporting through a cummulative-effect adjustment at the beginning of the period of adoption. First quarter of 2019 We are currently evaluating this ASU and expect the adoption to increase both our total assets and total liabilities by less than 1%. We do not currently expect the adoption to have an impact on our consolidated results of operations.

Schedules of Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements	Recently Adopted Accounting Pronouncements Description Adoption Date Effect on Financial Statements Since 2014, the Financial Accounting Standards Board ("FASB") has issued several amendments to its guidance on revenue recognition. The amended guidance, among other things, introduces a new framework for a single comprehensive model that can be used when accounting for revenue and supersedes most current revenue recognition guidance, including that which pertains to specific industries. The core principle states that an entity should recognize revenue to depict the transfer of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for such goods and services. It also requires expanded quantitative and qualitative disclosures that will enable financial statement users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

Summary of the company's CLO compliance tests as of the most recent determination dates	A summary of our CLO compliance tests as of the most recent determination dates in October 2018 is as follows: Cash Flow Triggers CLO VI CLO VII CLO VIII CLO IX CLO X Overcollateralization (1) Current 129.87 % 129.03 % 129.03 % 134.68 % 126.98 % Limit 128.87 % 128.03 % 128.03 % 133.68 % 125.98 % Pass / Fail Pass Pass Pass Pass Pass Interest Coverage (2) Current 208.68 % 212.40 % 268.75 % 276.05 % 236.32 % Limit 120.00 % 120.00 % 120.00 % 120.00 % 120.00 % Pass / Fail Pass Pass Pass Pass Pass (1) The overcollateralization ratio divides the total principal balance of all collateral in the CLO by the total principal balance of the bonds associated with the applicable ratio. To the extent an asset is considered a defaulted security, the asset’s principal balance for purposes of the overcollateralization test is the lesser of the asset’s market value or the principal balance of the defaulted asset multiplied by the asset’s recovery rate which is determined by the rating agencies. Rating downgrades of CLO collateral will generally not have a direct impact on the principal balance of a CLO asset for purposes of calculating the CLO overcollateralization test unless the rating downgrade is below a significantly low threshold (e.g. CCC-) as defined in each CLO vehicle. (2) The interest coverage ratio divides interest income by interest expense for the classes senior to those retained by us.
