Part I
Item 1.    Business
Our Company
Western Asset Mortgage Capital Corporation, a Delaware corporation, and Subsidiaries (the “Company” unless otherwise indicated or except where the context otherwise requires “we,” “us” or “our”) commenced operations in May 2012, focused on investing in, financing and managing a diversified portfolio of real estate related securities, whole loans and other financial assets, which we collectively refer to as our target assets.  We are externally managed by Western Asset Management Company, LLC (our “Manager”) pursuant to the terms of a management agreement. We conduct our operations to qualify and be taxed as a real estate investment trust, or REIT, for U.S. federal income tax purposes. Accordingly, we generally will not be subject to U.S. federal income taxes on our taxable income that we distribute currently to our stockholders as long as we maintain our intended qualification as a REIT. However, certain activities that we may perform may cause us to earn income which will not be qualifying income for REIT purposes. We have designated a subsidiary as a taxable REIT subsidiary, or TRS, to engage in such activities. We also intend to operate our business in a manner that permits us to maintain our exemption from registration under the 1940 Act, as amended, or the Investment Company Act. Our common stock is traded on the New York Stock Exchange, or the NYSE, under the symbol "WMC."

Our objective is to provide attractive risk adjusted returns to our stockholders primarily through an attractive dividend, we intend to support with sustainable core earnings, as well as the potential for higher returns through capital appreciation. Our investment strategy is based on our Manager's perspective of which mix of our target assets it believes provides us with the best risk-reward opportunities at any given time.  We also deploy leverage as part of our investment strategy to increase potential returns. 
Our Manager
We are externally managed and advised by our Manager, an SEC-registered investment advisor and a wholly-owned subsidiary of Legg Mason, Inc.("Legg Mason"), headquartered in Pasadena, California, that specializes in fixed-income asset management. From offices in Pasadena, Hong Kong, London, Melbourne, New York, São Paulo, Singapore, Tokyo and Zurich, our Manager's 835 employees provide investment services for a wide variety of global clients, including mutual funds, corporate, public, insurance, health care, union organizations and charitable foundations. In addition, two of our directors, James W. Hirschmann III and Jennifer W. Murphy, are also employees of our Manager. Our Manager is responsible for, among other duties: (i) performing all of our day-to-day functions; (ii) determining investment criteria in conjunction with our Board of Directors; (iii) sourcing, analyzing and executing investments, asset sales and financings; (iv) performing asset management duties; and (v) performing financial and accounting management.
On February 18, 2020, Franklin Resources, Inc. (“Franklin”) and Legg Mason, announced that they had entered into an agreement under which Franklin would acquire Legg Mason and its affiliates, including our Manager.   The transaction is expected to close in the third quarter of 2020 and is subject to customary closing conditions.  Upon completion of the transaction our Manager would become a wholly owned subsidiary of Franklin.
Our Competitive Advantages
Our competitive advantages in the marketplace stems from our relationship with our Manager. As of December 31, 2019, our Manager had approximately $460.1 billion in assets under management. Our Manager's scale makes it an important trading partner for many of the largest broker-dealers and banks, which provides our investment team the ability to source real estate related opportunities directly from originators as well as access attractive financing.
Our Investment Strategy
 
Our Manager’s investment philosophy, which developed from a singular focus in fixed-income asset management over a variety of credit cycles and conditions, is to provide clients with a diversified, long-term value-oriented portfolio. We benefit from the breadth and depth of our Manager’s overall investment philosophy, which focuses on a macroeconomic analysis as well as an in-depth analysis of individual assets and their relative value. In making investment decisions on our behalf, our Manager seeks to identify assets across the broad mortgage universe with attractive risk adjusted returns, which incorporates its view on the outlook for the mortgage markets, including relative valuation, supply and demand trends, the level of interest rates, the shape of the yield curve, prepayment rates, financing and liquidity, commercial and residential real estate prices, delinquencies, default rates, recovery of various segments of the economy and vintage of collateral, subject to maintaining our REIT qualification and our exemption from registration under the 1940 Act.

Our Target Assets

     Agency RMBS. — Agency RMBS, which are RMBS for which the principal and interest payments are guaranteed by a U.S. Government agency, such as the Government National Mortgage Association (“GNMA” or “Ginnie Mae”), or a U.S. Government-sponsored entity ("GSE"), such as the Federal National Mortgage Association (“FNMA” or “Fannie Mae”) or the Federal Home Loan Mortgage Corporation (“FHLMC” or “Freddie Mac”).  The Agency RMBS we acquire can be secured by fixed-rate mortgages, adjustable-rate mortgages or hybrid adjustable-rate mortgages. Fixed-rate mortgages have interest rates that are fixed for the term of the loan and do not adjust. The interest rates on adjustable-rate mortgages generally adjust annually (although some may adjust more frequently) to an increment over a specified interest rate index. Hybrid adjustable-rate mortgages have interest rates that are fixed for a specified period of time (typically three, five, seven or ten years) and, thereafter, adjust to an increment over a specified interest rate index. Adjustable-rate mortgages and hybrid adjustable-rate mortgages generally have periodic and lifetime constraints on the amount by which the loan interest rate can change on any predetermined interest rate reset date.

 Agency CMBS. — Fixed and floating rate CMBS, for which the principal and interest payments are guaranteed by a U.S. Government agency or U.S. Government-sponsored entity, but for which the underlying mortgage loans are secured by real property other than single family residences. These may include, but are not limited to Fannie Mae DUS (Delegated Underwriting and Servicing) MBS, Freddie Mac Multifamily Mortgage Participation Certificates, Ginnie Mae project loan pools, and/or CMOs structured from such collateral. These securities generally have prepayment protection in the form of defeasance, yield maintenance or points.

Non-Agency RMBS. — RMBS that are not guaranteed by a U.S. Government agency or U.S. Government-sponsored entity. The mortgage loan collateral for Non-Agency RMBS consists of residential mortgage loans that do not generally conform to underwriting guidelines issued by a U.S. Government agency or U.S. Government-sponsored entity due to certain factors, including mortgage balances in excess of Agency underwriting guidelines, borrower characteristics, loan characteristics and/or level of documentation, and therefore are not issued or guaranteed by a U.S. Government agency or U.S. Government-sponsored entity. The mortgage loan collateral may be classified as subprime, Alternative-A or prime depending on the borrower’s credit rating and the underlying level of documentation. Non-Agency RMBS collateral may also include reperforming loans, which are conventional mortgage loans that were current at the time of the securitization, but had been delinquent in the past. Non-Agency RMBS may be secured by fixed-rate mortgages, adjustable-rate mortgages or hybrid adjustable-rate mortgages.
 
Non-Agency CMBS. — Fixed and floating rate CMBS for which the principal and interest payments are not guaranteed by a U.S. Government agency or U.S. Government-sponsored entity.  We do not have an established minimum current rating requirement for such investments.

Non U.S. CMBS.   CMBS which is not guaranteed by a U.S. Government agency or U.S. Government-sponsored entity and which is secured by commercial real estate located outside of the U.S.  Although our Manager believes that these investments can provide attractive risk-reward opportunities and offer additional asset diversification, investing in international real estate has a number of additional risks, including, but not limited to, currency risk, political risk and the legal risk of investing in jurisdictions with varying laws and regulations and potential tax implications. 

GSE Risk Sharing Securities Issued by Fannie Mae and Freddie Mac. — From time to time we have and may in the future continue to invest in risk sharing securities issued by Fannie Mae and Freddie Mac.  Principal and interest payments on these securities are based on the performance of a specified pool of Agency residential mortgages. The payments due on these securities, however, are not secured by the referenced mortgages. The payments due are full faith and credit obligations of Fannie Mae or Freddie Mac respectively, but neither agency guarantees full payment of the underlying mortgages.  Investments in these securities generally are not qualifying assets for purposes of the 75% real estate asset test applicable to REITs and generally do not generate qualifying income for purposes of the 75% real estate income test applicable to REITs. As a result, we may be limited in our ability to invest in such assets.

TBAs. — We may utilize TBAs, in order to invest in Agency RMBS. Pursuant to these TBAs, we agree to purchase (or deliver), for future settlement, Agency RMBS with certain principal and interest terms and certain underlying collateral, but the particular Agency RMBS to be delivered is not identified until shortly before the TBA settlement date. Our ability to invest in Agency RMBS through TBAs may be limited by the 75% real estate income and asset tests applicable to REITs.

Mortgage pass-through certificates. — Mortgage pass-through certificates are securities representing interests in “pools” of mortgage loans secured by residential real property where payments of both interest and scheduled principal, plus pre-paid principal, on the underlying loan pools are made monthly to holders of the securities, in effect “passing through” monthly payments made by the individual borrowers on the mortgage loans that underlie the securities, net of fees paid to the issuer/guarantor of the securities and servicers of the underlying mortgages.

Interest-Only Strips or IOs. — This type of security entitles the holder only to payments of interest based on a notional principal balance. The yield to maturity of Interest-Only Strips is extremely sensitive to the rate of principal payments (particularly prepayments) on the underlying pool of mortgages. We invest in these types of securities primarily to take advantage of particularly attractive prepayment-related or structural opportunities in the MBS markets, as well as to help manage the duration of our overall portfolio.
 
Inverse Interest-Only Strips or IIOs. — This type of security has a coupon with an inverse relationship to its index and is subject to caps and floors. Inverse Interest-Only MBS entitles the holder to interest only payments based on a notional principal balance, which is typically equal to a fixed rate of interest on the notional principal balance less a floating rate of interest on the notional principal balance that adjusts according to an index subject to set minimum and maximum rates. The current yield of Inverse Interest-Only MBS will generally decrease when its related index rate increases and increase when its related index rate decreases.
 
Agency and Non-Agency CMBS IO and IIO Securities. — Interest-Only and Inverse Interest-Only securities for which the underlying collateral is commercial mortgages the principal and interest on which may or may not be guaranteed by a U.S. Government agency or U.S. Government-sponsored entity.  Unlike single family residential mortgages in which the borrower, generally, can prepay at any time, commercial mortgages frequently limit the ability of the borrower to prepay, thereby providing a certain level of prepayment protection.  Common restrictions include yield maintenance and prepayment penalties, the proceeds of which are generally at least partially allocable to these securities, as well as, defeasance.
 
Principal-Only Strips or POs. — This type of security generally only entitles the holder to receive cash flows that are derived from principal repayments of an underlying loan pool, but in the case of Non-Agency Principal-Only Strips will also include cash flows from default recoveries and excess interest.  The yield to maturity of Principal-Only Strips is extremely sensitive to the rate of principal payments (particularly prepayments) on the underlying pool of mortgages. We invest in these types of securities primarily to take advantage of structural opportunities in the MBS markets.
 
Residential Whole Loans. — Residential Whole Loans are mortgages secured by single family residences held directly by us or through consolidated trusts with us holding the beneficial interest in the trusts. Our Residential Whole Loans include conforming fixed rate mortgages and adjustable rate mortgages that do not qualify for the Consumer Finance Protection Bureau’s (or CFPB) safe harbor provision for “qualified mortgages” ("Non QM" mortgages). Our Manager’s review, relating to Non QM mortgages, includes an analysis of the loan originator’s procedures and documentation for compliance with Ability-to-Repay requirements. As discussed in Note 7 "Financing," we have and may continue to securitize whole-loan interests, selling more senior interests in the pool of loans and retaining residual portions.  The characteristics of our Residential Whole Loans may vary going forward.

Residential Bridge Loans. Residential Bridge Loans are mortgages secured by non owner occupied single family and multi-family residences, typically short-term, held directly by us or through structured Non-Agency RMBS programs crafted specifically for us and other clients of our Manager.  These loans are held in a consolidated trust with us holding the beneficial interest in the trust. 
 
Commercial Whole Loans. — Commercial Whole Loans are generally loans ranging from, $5.0 million to $125.0 million, secured by commercial real estate typically short-term loans. The collateral types may include hospitality, senior care living facilities, multifamily, office, retail and industrial properties. These loans may be held directly by us or through consolidated trusts with us holding the beneficial interest in the trust.

Commercial Mezzanine Loans. Commercial mezzanine loans are generally structured to represent a senior position in the borrower’s equity in, and subordinate to a first mortgage loan, on a property. These loans are generally secured by pledges of ownership interests, in whole or in part, in entities that directly or indirectly own the real property. At times, mezzanine loans may be secured by additional collateral, including letters of credit, personal guarantees, or collateral unrelated to the property. Mezzanine loans may be structured to carry either fixed or floating interest rates as well as carry a right to participate in a percentage of gross revenues and a percentage of the increase in the fair market value of the property securing the loan. Mezzanine loans may also contain prepayment lockouts, penalties, minimum profit hurdles and other mechanisms to protect and enhance returns to the lender. Mezzanine loans usually have maturities that match the maturity of the related mortgage loan but may have shorter

4




or longer terms. Depending on the structure of a transaction, Commercial Mezzanine loans may or may not qualify as "qualifying real estate interests" for purposes of the 1940 Act.

Collateralized Mortgage Obligations or CMOs. — These are securities, which can be Agency or Non-Agency, that are structured from residential and/or commercial pass-through certificates, which receive monthly payments of principal and interest. CMOs divide the cash flows which come from the underlying mortgage pass-through certificates into different classes of securities that may have different maturities and different weighted average lives than the underlying pass-through certificates.

ABS. — Debt and/or equity tranches of securitizations backed by various asset classes, including, but not limited to, automobiles, credit cards, equipment, franchises, recreational vehicles and student loans. Investments in ABS generally are not qualifying assets for purposes of the 75% real estate asset test applicable to REITs and generally do not generate qualifying income for purposes of the 75% real estate income test applicable to REITs. As a result, we may be limited in our ability to invest in such assets.

     Other investments. — In addition to MBS, our principal investment, and ABS from time to time, we may also make other investments in securities, which our Manager believes will assist us in meeting our investment objective and are consistent with our overall investment policies.  These investments will normally be limited by the REIT requirements that 75% our assets be real estate assets and that 75% of our income be generated from real estate, thereby limiting our ability to invest in such assets.

Our Investment Portfolio

Our investment portfolio composition at December 31, 2019.    

Investment Portfolio

CHART-8722CB306B675778835.JPG

Our Financing Strategy

We deploy leverage to increase potential returns to our stockholders and to fund the acquisition of our target assets. While we are not required to maintain any particular leverage ratio, we expect to maintain a debt-to-equity ratio of three to ten times the amount of our stockholders’ equity, depending on our investment composition. The amount of leverage we use for our portfolio depends upon a variety of factors, such as, general economic, political and financial market conditions, the anticipated liquidity and price volatility of our assets, the availability and cost of financing the assets, the credit worthiness of financing counterparties and the health of the U.S. residential and commercial mortgage markets. At December 31, 2019, our aggregate debt-to-equity

5




ratio was approximately 5.4 to 1 excluding our non-recourse debt and 8.0 to 1 including our non-recourse debt. The debt-to-equity ratio is not a comprehensive statement of overall investment portfolio leverage which is affected by any leverage embedded in TBAs and derivative instruments.

Repurchase Agreements

We primarily finance our investments through repurchase agreements for which we pledge our assets. Our repurchase agreements have maturities generally ranging from one to twelve months, but in some cases longer. Repurchase agreements involve the transfer of the pledged collateral to a counterparty at an agreed upon price in exchange for such counterparty’s simultaneous agreement to return the same security back to the borrower at a future date (i.e., the maturity of the borrowing). Under our repurchase agreements, we retain beneficial ownership of the pledged collateral, while the counterparty maintains custody of such collateral.  At the maturity of a repurchase financing, unless the repurchase financing is renewed with the same counterparty, we are required to repay the loan, including any accrued interest, and concurrently reacquire custody of the pledged collateral or, with the consent of the counterparty, we may renew the repurchase financing at the then prevailing market interest rate and terms.  The amount borrowed under our repurchase agreements is a specified percentage of the asset’s applicable fair value, which is dependent on the collateral type.  Our repurchase agreement counterparties generally require collateral in excess of the loan amount, or haircuts. As of December 31, 2019, the ranges of the haircuts on our investments were as follow:

 
 
Minimum
 
Maximum (excluding IOs and IIOs)

(1) Includes Residential Bridge Loans.
(2) Includes Securitized commercial loans.
(3) For Agency CMBS whose payment is not guaranteed by Freddie Mac haircuts can be as high as 25%.
 
A significant decrease in asset value, advance rate, or an increase in the haircut could result in us having to sell assets in order to meet additional margin calls by our repurchase agreement counterparties. Our inability to post adequate collateral for a margin call by the counterparty could result in a condition of default under our repurchase agreements. We expect to mitigate our risk to margin calls by deploying leverage at the portfolio level at amounts below our available financing under our repurchase agreements.

In order to reduce our exposure of risk associated with concentration to any one repurchase agreement counterparty, we seek to diversify our exposure by entering into repurchase agreements with multiple counterparties. At December 31, 2019, we had 34 master repurchase agreements with our counterparties and outstanding borrowings under 21 of such agreements. Our total outstanding borrowings under our repurchase agreements was $2.8 billion, with a maximum net exposure to any single repurchase agreement counterparty of $132.3 million, or 23.4% of equity.

Convertible Senior Unsecured Notes

As of December 31, 2019, we had $205.0 million of 6.75% convertible senior unsecured notes outstanding. The notes mature on October 1, 2022, unless earlier converted, redeemed or repurchased by the holders pursuant to their terms, and are not redeemable by us except during the final three months prior to maturity. We view this financing as an attractive source of longer-term capital, which we believe was more cost efficient than issuing straight equity.

Securitized Debt

As of December 31, 2019, Arroyo Mortgage Trust 2019-2 (a subsidiary) had $801.1 million securitized mortgage backed notes outstanding . The notes, excluding the Owner Certificates, issued by were four classes, with a weighted average fixed interest rate of 3.425% per annum. All of the Notes are anticipated to have a final payment date in April 2049. We view the notes as an

6




attractive source of longer-term financing for our Residential Whole Loan portfolio. We may redeem the offered notes on or after the earlier of (i) the three-year anniversary of the closing date or ii) the date on which the aggregate collateral balance is 20% of the original principal balance. The notes are redeemable at their face value plus accrued interest. The mortgage-backed notes are classified in "Securitized Debt" in the Consolidated Balance Sheets.

Separately, as of December 31, 2019, the Company had three consolidated variable interest entities that had outstanding borrowings of $681.7 million, which is classified in "Securitized Debt" in the Consolidated Balance Sheets.


 
Our Hedging and Risk Management Strategy
 
Our overall portfolio strategy is designed to generate attractive returns to our investors through various economic cycles. We believe our broad approach to investing in the real estate mortgage markets, which considers all categories of real estate assets, allows us to invest in a diversified portfolio and help mitigate our portfolio from risks that arise from investing in a single or limited collateral type. In connection with our risk management activities, we enter into a variety of derivative and non-derivative instruments. Our primary objective for acquiring these derivatives and non-derivative instruments is to mitigate our exposure to future events that are outside our control. Our derivative instruments are designed to mitigate the effects of market risk and cash flow volatility associated with interest rate risk, including prepayment risk. As part of our hedging strategy, we may enter into interest rate swaps, including forward starting swaps, interest rate swaptions, U.S. Treasury options, future contracts, TBAs, total return swaps, credit default swaps, foreign current swaps and forwards and other similar instruments.

Regulation
REIT Qualification
We elected to be taxed as a REIT under Section 856 through 860 of the Internal Revenue Code of 1986, as amended (the "Code"), commencing with our taxable year ended December 31, 2012. We will generally not be subject to corporate U.S. federal income tax to the extent that we make qualifying distributions to stockholders, and provided that we satisfy, on a continuing basis, through actual investment and operating results, the REIT requirements including certain asset, income, distribution and stock ownership tests. If we fail to qualify as a REIT, and do not qualify for certain statutory relief provisions, we will be subject to U.S. federal, state and local income taxes and may be precluded from qualifying as a REIT for the subsequent four taxable years following the year in which we lost our REIT qualification. The failure to qualify as a REIT could have a material adverse impact on our results of operations and amounts available for distribution to stockholders.
Investment Company Act Exemption
We conduct our operations so that we are not considered an investment company under the 1940 Act in reliance on the exemption provided by Section 3(c)(5)(C) of the 1940 Act. Section 3(c)(5)(C), as interpreted by the staff of the SEC, requires that: (i) at least 55% of our investment portfolio consist of "mortgages and other liens on and interest in real estate," or "qualifying real estate interests," and (ii) at least 80% of our investment portfolio consist of qualifying real estate interests plus "real estate-related assets." We have relied and intend to continue to rely on current interpretations of the staff of the SEC in an effort to continue to qualify for an exemption from registration under the 1940 Act. For more information on the exemptions that we utilize refer to Item 1A, "Risk Factors" of this annual report on Form 10-K.
Competition
Our net income depends, in part, on our ability to acquire assets at favorable spreads over our borrowing costs. In acquiring our target assets, we compete with other REITs, specialty finance companies, savings and loan associations, banks, mortgage bankers, insurance companies, mutual funds, institutional investors, investment banking firms, financial institutions, governmental bodies and other entities. In addition, other REITs with similar asset acquisition objectives, including a number that have been recently formed and others that may be organized in the future, compete with us in acquiring assets and obtaining financing. These competitors may be significantly larger than us, may have access to greater capital and other resources or may have other advantages. In addition, some competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments, and establish more relationships, than us. Current market conditions may attract more competitors, which may increase the competition for sources of financing. An increase in the competition for sources of funding could adversely affect the availability and cost of financing, and thereby adversely affect the market price of our common stock.
Employees

7




We are externally managed pursuant to the management agreement dated May 9, 2012. We have no employees. All of our officers and two of our directors, James W. Hirschmann III and Jennifer W. Murphy, are employees of our Manager. Our Manager is responsible for, among other duties: (i) performing all of our day-to-day functions; (ii) determining investment criteria in conjunction with our Board of Directors; (iii) sourcing, analyzing and executing investments, asset sales and financings; (iv) performing asset management duties; and (v) performing financial and accounting management.
Corporate Governance and Internet Address
We emphasize the importance of professional business conduct and ethics through our corporate governance initiatives. In 2014, the Board took additional steps to enhance governance by appointing a lead independent director and adding a fourth independent director so that our Board of Directors consists of two-thirds independent directors. The audit, nominating and corporate governance, risk, and compensation committees of our Board of Directors are composed entirely of independent directors. We have adopted corporate governance guidelines and a code of business conduct and ethics, which delineate our standards for our officers and directors.
Our internet address is www.westernassetmcc.com. The information on our website is not incorporated by reference in this Annual Report on Form 10-K. We make available, free of charge through a link on our site, our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to such reports, if any, as filed or furnished with the SEC, as soon as reasonably practicable after such filing or furnishing. Our site also contains our code of business conduct and ethics, corporate governance guidelines and the charters of our audit committee, nominating and corporate governance committee and compensation committee of our Board of Directors. Within the time period required by the rules of the SEC and the New York Stock Exchange, or NYSE, we will post on our website any amendment to our code of business conduct and ethics as defined in the code. Our documents filed with, or furnished to, the SEC are also available for review on the SEC's website at www.sec.gov.
Item 1A.    Risk Factors
Our business and operations are subject to a number of risks and uncertainties, the occurrence of which could adversely affect our business, financial condition, results of operations and ability to make distributions to stockholders and could cause the value of our capital stock to decline.
Risks related to our business
We may not be able to successfully operate our business or generate sufficient revenue to make or sustain distributions to our stockholders.
We cannot assure you that we will be able to continue to operate our business successfully or implement our operating policies and strategies as described herein. The results of our operations depend on several factors, including the availability of opportunities for the acquisition of assets, the level and volatility of interest rates, the availability of adequate short and long-term financing, conditions in the financial markets and economic conditions.
We may change any of our strategies, policies or procedures without stockholder consent.
We may change any of our strategies, policies or procedures with respect to investments, acquisitions, growth, operations, indebtedness, capitalization, distributions, financing strategy and leverage at any time without the consent of our stockholders, which could result in an investment portfolio with a different risk profile. A change in our investment strategy may increase our exposure to interest rate risk, default risk and real estate market fluctuations. Furthermore, a change in our asset allocation could result in our making investments in asset categories different from those described herein. These changes could adversely affect our financial condition, results of operations, the market price of our common stock and our ability to make distributions to our stockholders.
Increases in interest rates could adversely affect the value of our investments and cause our interest expense to increase, which could result in reduced earnings or losses and negatively affect our profitability as well as the cash available for distribution to our stockholders.
Our investment portfolio contains a significant allocation to MBS, as well Residential Whole Loans. The relationship between short-term and longer-term interest rates is often referred to as the “yield curve.” In a normal yield curve environment, an investment in such assets will generally decline in value if long-term interest rates increase. Declines in market value may ultimately reduce earnings or result in losses to us, which may negatively affect cash available for distribution to our stockholders. Ordinarily, short-term interest rates are lower than longer-term interest rates. If short-term interest rates rise disproportionately relative to longer-term interest rates (a flattening of the yield curve), our borrowing costs will generally

8




increase more rapidly than the interest income earned on our assets. Because our investments on average, generally bear interest based on longer-term rates than our borrowings, a flattening of the yield curve would tend to decrease our net interest margin, net income, book value and the market value of our net assets. It is also possible that short-term interest rates may exceed longer-term interest rates (a yield curve inversion), in which event our borrowing costs may exceed our interest income and we could incur operating losses. Additionally, to the extent cash flows from investments that return scheduled and unscheduled principal are reinvested, the spread between the yields on the new investments and available borrowing rates may decline, which would likely decrease our net income. A significant risk associated with our target assets is the risk that both long-term and short-term interest rates will increase significantly. If long-term rates increase significantly, the market value of these investments will decline, and the duration and weighted average life of the investments will increase. At the same time, an increase in short-term interest rates will increase the amount of interest owed on the repurchase agreements we enter into to finance the purchase of our investments.

Changes to, or the elimination of, LIBOR may adversely affect interest expense related to our loans and investments.
In July 2017, the United Kingdom Financial Conduct Authority (the authority that regulates LIBOR) announced it intends to stop persuading or compelling banks to submit rates for the calculation of LIBOR after 2021. The Alternative Reference Rates Committee (“ARRC”) has proposed that the Secured Overnight Financing Rate (“SOFR”) is the rate that represents best practice as the alternative to USD-LIBOR for use in derivatives and other financial contracts that are currently indexed to USD-LIBOR. ARRC has proposed a paced market transition plan to SOFR from USD-LIBOR and organizations are currently working on industry wide and company specific transition plans as it relates to derivatives and cash markets exposed to USD-LIBOR. We have material contracts, including agreements governing certain of our indebtedness, that are indexed to USD-LIBOR and are monitoring this activity and evaluating the related risks. In addition, approximately half of our investment portfolio pays interest at a variable rate that is tied to LIBOR. If LIBOR is no longer available, we may need to renegotiate some of our agreements to determine a replacement index or rate of interest. To the extent the replacement index or rate of interest is lower than the existing LIBOR-based rate it could have an adverse impact on the value of such investments, our financial condition and results of operations. In September 2019, the FASB proposed guidance that would help facilitate the market transition from existing reference rates to alternative rates. However, at this time, it is not possible to predict the effect of any such changes, any establishment of alternative reference rates or any other reforms to LIBOR that may be enacted in the United Kingdom or elsewhere. Uncertainty as to the nature of such potential changes, alternative reference rates or other reforms may adversely affect the trading market for LIBOR-based securities, including our material contracts that are indexed to USD-LIBOR. Furthermore, we may need to renegotiate any agreements governing our indebtedness extending beyond 2021 that utilize LIBOR as a factor in determining the interest rate to replace LIBOR with the new standard that is established. There is currently no definitive information regarding the future utilization of LIBOR or of any particular replacement rate. As such, potential effect of any such event on our business, financial condition and results of operations cannot yet be determined.

We cannot assure you that our internal controls over financial reporting will consistently be effective.
We are responsible for establishing and maintaining adequate internal control over financial reporting designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. We cannot ensure you that there will not be any material weaknesses or significant deficiencies in our internal control over financial reporting in the future.
Cybersecurity risk and cyber incidents may adversely affect our business by causing a disruption to our operations, a compromise or corruption of our confidential information and/or damage to our business relationships, all of which could negatively impact our financial results.
A cyber incident is considered to be any adverse event that threatens the confidentiality, integrity or availability of our information resources. These incidents may be an intentional attack or an unintentional event and could involve gaining unauthorized access to our information systems for purposes of misappropriating assets, stealing confidential information, corrupting data or causing operational disruption. The result of these incidents may include disrupted operations, misstated or unreliable financial data, liability for stolen assets or information, increased cybersecurity protection and insurance cost, litigation and damage to our investor relationships. As our reliance on technology has increased, so have the risks posed to both our information systems, both internal and those provided by our Manager and third party service providers. Our Manager has implemented processes, procedures and internal controls to help mitigate cybersecurity risks and cyber intrusions, but these measures, as well as our increased awareness of the nature and extent of a risk of a cyber incident, do not guarantee that our financial results, operations or confidential information will not be negatively impacted by such an incident.

Risks related to our investing strategy
Our investments in Non-Agency MBS, Residential Whole Loans, Commercial Loans and Residential Bridge Loans involve credit risks, which could materially adversely affect our results of operations.

The holder of a residential mortgages, commercial mortgages or MBS assumes the risk that the related borrowers may default on their obligations to make full and timely payments of principal and interest. Under our investment policy, we have the ability to acquire Non-Agency MBS, Residential Whole Loans, Commercial Loans and Residential Bridge Loans. In general, these investments carry greater investment risk than Agency MBS because the former are not guaranteed as to principal or interest by the U.S. Government, any federal agency or any federally chartered corporation. Higher-than-expected rates of default and/or higher-than-expected loss severities on these investments could adversely affect the value of these assets. Accordingly, defaults in the payment of principal and/or interest on our Residential Whole Loans, Commercial Loans, Residential Bridge Loans, and Non-Agency MBS and would likely result in our incurring losses of income from, and/or losses in market value relating to, these assets, which could materially adversely affect our results of operations.

In particular, our portfolio of Residential Whole Loans and Commercial Loans continued to be one of our faster growing asset class during 2019. We expect that our investment portfolio in Residential Whole Loans and Commercial Loans will continue to increase during 2020. As a holder of these loans, we are subject to the risk that the related borrowers may default or have defaulted on their obligations to make full and timely payments of principal and interest. A number of factors impact a borrower’s ability to repay including, among other things, changes in employment status, changes in interest rates or the availability of credit, and changes in real estate values. In addition to the credit risk associated with these assets, Residential Whole Loans and Commercial Loans are less liquid than certain of our other credit sensitive assets, which may make them more difficult to dispose of if the need or desire arises. If actual results are different from our assumptions in determining the prices paid to acquire such loans, particularly if the market value of the underlying properties decreases significantly subsequent to purchase, we may incur significant losses, which could materially adversely affect our results of operations.

We operate in a highly competitive market for investment opportunities and competition may limit our ability to acquire
desirable investments in our portfolio assets and could also affect the pricing of these securities.

We operate in a highly competitive market for investment opportunities. Currently, our profitability depends, in large part, on our ability to acquire our portfolio assets at attractive prices. In acquiring these assets, we compete with a variety of institutional investors, including other REITs, specialty finance companies, public and private funds (including other funds managed by our Manager), commercial and investment banks, commercial finance and insurance companies and other financial institutions. Many of our competitors are substantially larger and have considerably greater financial, technical, marketing and other resources than we do. Other REITs have recently raised, or may raise, additional capital, and may have investment objectives that overlap with ours, which may create additional competition for investment opportunities. Some competitors may have a lower cost of funds and access to funding sources that may not be available to us, such as funding from the U.S. Government. Many of our competitors are not subject to the operating constraints associated with REIT tax compliance or maintenance of an exemption from the 1940 Act. In addition, some of our competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, competition for investments in our portfolio assets may lead to the price of such assets increasing, which may further limit our ability to generate desired returns. We cannot assure you that the competitive pressures we face will not have a material adverse effect on our business, financial condition and results of operations. Also, as a result of this competition, desirable investments in these assets may be limited in the future and we may not be able to take advantage of attractive investment opportunities from time to time, as we can provide no assurance that we will be able to identify and make investments that are consistent with our investment objectives.
A lack of liquidity in our investments may adversely affect our business.
Many of the assets we acquire are not publicly traded. A lack of liquidity may result from the absence of a willing buyer or an established market for these assets, as well as legal or contractual restrictions on resale or the unavailability of financing for these assets. In addition, mortgage-related assets generally experience periods of illiquidity, especially during periods of economic stress such as the economic recession in 2008 which resulted in increased delinquencies and defaults with respect to residential and commercial mortgage loans. The illiquidity of our investments may make it difficult for us to sell such investments if the need or desire arises. In addition, if we are required to liquidate all or a portion of our portfolio quickly, we may realize significantly less than the value at which we have previously recorded our investments. Further, we may face other restrictions on our ability to liquidate an investment in a business entity to the extent that we or our Manager has or could be attributed with material, non-

10




public information regarding such business entity. As a result, our ability to vary our portfolio in response to changes in economic and other conditions may be relatively limited, which could adversely affect our results of operations and financial condition.
An economic recession and declining real estate values could impair our assets and harm our operations.
The risks associated with our business are more severe during economic recessions and are compounded by declining real estate values. The Residential Whole Loans, Residential Bridge Loans, Commercial Loans, Non-Agency RMBS and Non-Agency CMBS in which we invest a part of our capital will be particularly sensitive to these risks. Declining real estate values will likely reduce the level of new mortgage loan originations since borrowers often use appreciation in the value of their existing properties to support the purchase of additional properties. Borrowers will also be less able to pay principal and interest on loans underlying the securities in which we invest if the value of residential and commercial real estate weakens further. Further, declining real estate values significantly increase the likelihood that we will incur losses on these investments in the event of default because the value of collateral on the mortgages underlying such securities may be insufficient to cover the outstanding principal amount of the loan. Any sustained period of increased payment delinquencies, foreclosures or losses could adversely affect our net interest income from these investments, which could have an adverse effect on our financial condition, results of operations and our ability to make distributions to our stockholders
Our investments in Residential Whole Loans, Residential Bridge Loans and Commercial Loans subject us to servicing-related risks, including those associated with foreclosure and liquidation.

We rely on third-party servicers to service and manage the mortgages underlying our loan portfolio. The ultimate returns generated by these investments may depend on the quality of the servicer. If a servicer is not vigilant in seeing that borrowers make their required monthly payments, borrowers may be less likely to make these payments, resulting in a higher frequency of default. If a servicer takes longer to liquidate non-performing mortgages, our losses related to those loans may be higher than originally anticipated. Any failure by servicers to service these mortgages and/or to competently manage and dispose of REO properties could negatively impact the value of these investments and our financial performance. In addition, while we have contracted with third-party servicers to carry out the actual servicing of the loans (including all direct interface with the borrowers), for loans that we purchase together with the related servicing rights, we are nevertheless ultimately responsible, vis-à-vis the borrowers and state and federal regulators, for ensuring that the loans are serviced in accordance with the terms of the related notes and mortgages and applicable law and regulation. In light of the current regulatory environment, such exposure could be significant even though we might have contractual claims against our servicers for any failure to service the loans to the required standard.

The foreclosure process, especially in judicial foreclosure states such as New York, Florida and New Jersey, can be lengthy and expensive, and the delays and costs involved in completing a foreclosure, and then subsequently liquidating the REO property through sale, may materially increase any related loss. In addition, at such time as title is taken to a foreclosed property, it may require more extensive rehabilitation than we estimated at acquisition. Thus, a material amount of foreclosed residential mortgage loans, particularly in the states mentioned above, could result in significant losses in our Residential Whole Loan portfolio and could materially adversely affect our results of operations.
The commercial mortgage loans underlying the CMBS and our Commercial Loans we may acquire are subject to defaults, foreclosure timeline extension, fraud and commercial price depreciation and unfavorable modification of loan principal amount, interest rate and amortization of principal, which could result in losses to us.
CMBS may be secured by a single commercial mortgage loan or a pool of commercial mortgage loans. Commercial mortgage loans may be secured by multifamily or commercial property and are subject to risks of delinquency and foreclosure, and risks of loss that may be greater than similar risks associated with loans made on the security of residential property. The ability of a borrower to repay a loan secured by an income-producing property typically is dependent primarily upon the successful operation of such property rather than upon the existence of independent income or assets of the borrower. If the net operating income of the property is reduced, the borrower's ability or willingness to repay the loan may be impaired. Net operating income of an income-producing property can be affected by, among other things,
tenant mix;
success of tenant businesses;
property management decisions;
property location and condition;
competition from comparable types of properties;

11




changes in laws that increase operating expenses or limit rents that may be charged;
any need to address environmental contamination at the property or the occurrence of any uninsured casualty at the property;
changes in national, regional or local economic conditions and/or specific industry segments;
declines in regional or local real estate values;
declines in regional or local rental or occupancy rates;
increases in interest rates;
real estate tax rates and other operating expenses;
changes in governmental rules, regulations and fiscal policies, including environmental legislation; and
acts of God, terrorist attacks, social unrest and civil disturbances.
If our Manager overestimates the loss-adjusted yields of our CMBS investments, we may experience losses.
Our Manager will analyze any CMBS investments we may acquire based on loss-adjusted yields, taking into account estimated future losses on the mortgage loans included in the securitization's pool of loans, and the estimated impact of these losses on expected future cash flows. Our Manager's loss estimates may not prove accurate, as actual results may vary from estimates. In the event that our Manager underestimates the pool level losses relative to the price we pay for a particular CMBS investment, we may experience losses with respect to such investment.
If we do not control the special servicing of the mortgage loans included in the CMBS in which we invest and, in such cases, the special servicer may take actions that could adversely affect our interests.
With respect to CMBS in which we invest, overall control over the special servicing of the related underlying mortgage loans will be held by a "directing certificateholder" or a "controlling class representative," which is appointed by the holders of the most subordinate class of CMBS in such series. We may not have the right to appoint the directing certificateholder. In connection with the servicing of the specially serviced mortgage loans, the related special servicer may, at the direction of the directing certificateholder, take actions with respect to the specially serviced mortgage loans that could adversely affect our interests.
Our investments are recorded at fair value, and quoted prices or observable inputs may not be available to determine such value, resulting in the use of significant unobservable inputs to determine value.
We expect that the values of some of our investments may not be readily determinable. We measure the fair value of these investments on at least a monthly basis. The fair value at which our assets are recorded may not be an indication of their realizable value. Ultimate realization of the value of an asset depends to a great extent on economic and other conditions that are beyond the control of our Manager, our Company or our Board of Directors. Further, fair value is only an estimate based on good faith judgment of the price at which an investment can be sold since market prices of investments can only be determined by negotiation between a willing buyer and seller. If we were to liquidate a particular asset, the realized value may be more than or less than the amount at which such asset is valued. Accordingly, the value of our common stock could be adversely affected by our determinations regarding the fair value of our investments, whether in the applicable period or in the future. Additionally, such valuations may fluctuate over short periods of time.
Our determination of the fair value of our investments for GAAP includes inputs provided by third party dealers and pricing services. Valuations of certain investments in which we invest are often difficult to obtain. In general, dealers and pricing services heavily disclaim their valuations. Dealers may claim to furnish valuations only as an accommodation and without special compensation, and so they may disclaim any and all liability for any direct, incidental, or consequential damages arising out of any inaccuracy or incompleteness in valuations, including any act of negligence or breach of any warranty. Depending on the complexity and illiquidity of a security, valuations of the same security can vary substantially from one dealer or pricing service to another. Therefore, our results of operations for a given period could be adversely affected if our determinations regarding the fair market value of these investments are materially different than the values that we ultimately realize upon their disposal. Due to an overall increase in market volatility, the valuation process has been particularly challenging recently as market events have made valuations of certain assets more difficult, unpredictable and volatile.
Declines in value of the assets in which we invest will adversely affect our financial position and results of operations, and make it more costly to finance these assets.

12




We use our investments as collateral for our financings. Any decline in their value, or perceived market uncertainty about their value, would likely make it difficult for us to obtain financing on favorable terms or at all, or maintain our compliance with terms of any financing arrangements already in place. Our investments in mortgage-backed securities and Whole Loans are recorded at fair value under a fair value option election at the time of purchase with changes in fair value reported in earnings. As a result, a decline in fair values of our mortgage-backed securities and Whole Loans could reduce both our earnings and stockholders' equity. If market conditions result in a decline in the fair value of our assets, our financial position and results of operations could be adversely affected.
Interest rate mismatches between our RMBS and Whole Loans backed by ARMs or hybrid ARMs and our borrowings used to fund our purchases of these assets may cause us to suffer losses.
We may fund our RMBS and Whole Loans with borrowings that have interest rates that adjust more frequently than the interest rate indices and repricing terms of RMBS and Whole Loans backed by adjustable-rate mortgages, or ARMs, or hybrid ARMs. Accordingly, if short-term interest rates increase, our borrowing costs may increase faster than the interest rates on RMBS and Whole Loans backed by ARMs or hybrid ARMs adjust. As a result, in a period of rising interest rates, we could experience a decrease in net income or a net loss.
In most cases, the interest rate indices and repricing terms of RMBS and Whole Loans backed by ARMs or hybrid ARMs and our borrowings will not be identical, thereby potentially creating an interest rate mismatch between our investments and our borrowings. While the historical spread between relevant short-term interest rate indices has been relatively stable, there have been periods when the spread between these indices was volatile. During periods of changing interest rates, these interest rate index mismatches could reduce our net income or produce a net loss, and adversely affect the level of our dividends and the market price of our common stock.
In addition, RMBS and Whole Loans backed by ARMs or hybrid ARMs will typically be subject to lifetime interest rate caps that limit the amount an interest rate can increase through the maturity of the RMBS and Whole Loans. However, our borrowings under repurchase agreements typically are not subject to similar restrictions. Accordingly, in a period of rapidly increasing interest rates, the interest rates paid on our borrowings could increase without limitation while caps could limit the interest rates on these types of RMBS and Whole Loans. This problem is magnified for RMBS and Whole Loans backed by ARMs or hybrid ARMs that are not fully indexed. Further, some RMBS and Whole Loans backed by ARMs or hybrid ARMs may be subject to periodic payment caps that result in a portion of the interest being deferred and added to the principal outstanding. As a result, we may receive less cash income on these types of RMBS and Whole Loans than we need to pay interest on our related borrowings. These factors could reduce our net interest income and cause us to suffer a loss during periods of rising interest rates.
As of December 31, 2019, our Non-Agency RMBS and Whole Loans were secured by ARMs, Hybrid ARMS, pay option ARMs and fixed-rate mortgages. There can be no assurance that this will not change in the future.
Prepayment may adversely affect our profitability.
The RMBS assets and Residential Whole Loans we acquire are backed by pools of residential mortgage loans. We receive payments, generally, from the payments that are made on these underlying residential mortgage loans. While commercial mortgages frequently include limitations on the ability of the borrower to prepay, residential mortgages generally do not. When borrowers prepay their residential mortgage loans at rates that are faster than expected, the net result is prepayments that are faster than expected on the related RMBS and Residential Whole Loans. These faster than expected payments may adversely affect our profitability.
We may purchase RMBS assets and Residential Whole Loans that have a higher interest rate than the then prevailing market interest rate. In exchange for this higher interest rate, we may pay a premium to par value to acquire the asset. In accordance with accounting rules, we amortize this premium over the expected term of the asset. If the asset is prepaid in whole or in part at a faster than expected rate, we must expense all or a part of the remaining unamortized portion of the premium, which can adversely affect our profitability.
Prepayments generally increase when interest rates fall and decrease when interest rates rise, but changes in prepayment are difficult to predict. House price appreciation, while increasing the value of the collateral underlying our RMBS and Residential Whole Loans, may increase prepayments as borrowers may be able to refinance at more favorable terms. Prepayments can also occur when borrowers default on their residential mortgages and the mortgages are prepaid from the proceeds of a foreclosure sale of the property (an involuntary prepayment), or when borrowers sell the property and use the sale proceeds to prepay the mortgage as part of a physical relocation. Prepayments also may be affected by conditions in the housing and financial markets, increasing defaults on residential mortgage loans, which could lead to an acceleration of the payment of the related principal, general economic conditions and the relative interest rates on fixed-rate mortgages and ARMs. While we seek to manage prepayment risk, in selecting RMBS and Residential Whole Loans investments we must balance prepayment risk against other

13




risks, the potential returns of each investment and the cost of hedging our risks. No strategy can completely insulate us from prepayment or other such risks, and we may deliberately retain exposure to prepayment or other risks.
In addition, a decrease in prepayment may adversely affect our profitability. When borrowers prepay their residential mortgage loans at slower than expected rates, prepayments on the RMBS may be slower than expected. These slower than expected payments may adversely affect our profitability. We may purchase RMBS assets that have a lower interest rate than the then prevailing market interest rate. In exchange for this lower interest rate, we may pay a discount to par value to acquire the asset. In accordance with accounting rules, we accrete this discount over the expected term of the asset based on our prepayment assumptions. If the asset is prepaid at a slower than expected rate, however, we must accrete the remaining portion of the discount at a slower than expected rate. This will extend the expected life of the asset and result in a lower than expected yield on assets purchased at a discount to par.
We could be materially and adversely affected by poor market conditions where the properties securing the mortgage loans underlying our investments are geographically concentrated.

Our performance depends on the economic conditions in markets in which the properties securing the mortgage loans underlying our investments are concentrated. As of December 31, 2019, a substantial portion of our investments had underlying properties in California. Our financial condition, results of operations, the market price of our common stock and our ability to make distributions to our stockholders could be materially and adversely affected by this geographic concentration if market conditions, such as an oversupply of space or a reduction in demand for real estate in an area, deteriorate in California. Moreover, due to the geographic concentration of properties securing the mortgages underlying our investments, the Company may be disproportionately affected by general risks such as natural disasters, including major wildfires, floods and earthquakes and , severe or inclement weather, should such developments occur in or near the markets in California in which such properties are located.
We may incur losses as a result of unforeseen or catastrophic events, including the emergence of a pandemic and acts of terrorism.
The occurrence of unforeseen or catastrophic events, including the emergence of a pandemic, such as coronavirus, or other widespread health emergency (or concerns over the possibility of such an emergency) terrorist attacks could create economic and financial disruptions, and could lead to operational difficulties that could impair our ability to manage our businesses.

We may make investments in non U.S. dollar denominated securities, which will be subject to currency rate exposure and risks associated with the uncertainty of foreign laws and markets.
Some of our real estate-related securities investments may be denominated in foreign currencies, and therefore, we expect to have currency risk exposure to any such foreign currencies. A change in foreign currency exchange rates may have an adverse impact on returns on our non U.S. dollar denominated investments. Although we may hedge our foreign currency risk subject to the REIT income tests, we may not be able to do so successfully and may incur losses on these investments as a result of exchange rate fluctuations. To the extent that we invest in non U.S. dollar denominated securities, in addition to risks inherent in the investment in securities generally discussed in this Form 10-K, we will also be subject to risks associated with the uncertainty of foreign laws and markets, including, but not limited to, unexpected changes in regulatory requirements, political and economic instability in certain geographic locations, difficulties in managing international operations, currency exchange controls, potentially adverse tax consequences, additional accounting and control expenses and the administrative burden of complying with a wide variety of foreign laws.
We are highly dependent on information systems and systems failures could significantly disrupt our business, which may, in turn, negatively affect the market price of our common stock and our ability to make distributions to all stockholders.
Our business is highly dependent on communications and information systems of our Manager and other third party service providers. Any failure or interruption of our Manager's or other third party service providers' systems could cause delays or other problems in our securities trading activities, which could have a material adverse effect on our operating results and negatively affect the market price of our common stock and our ability to make distributions to our stockholders.
Loss of our exemption from regulation pursuant to the 1940 Act would adversely affect us.
We conduct our business so as not to become regulated as an investment company under the 1940 Act in reliance on the exemption provided by Section 3(c)(5)(C) of the 1940 Act. Section 3(c)(5)(C), as interpreted by the staff of the SEC, requires that: (i) at least 55% of our investment portfolio consist of "mortgages and other liens on and interest in real estate," or "qualifying real estate interests," and (ii) at least 80% of our investment portfolio consist of qualifying real estate interests plus "real estate-related assets." In satisfying this 55% requirement, based on pronouncements of the SEC staff, we may treat whole pool Agency RMBS

14




and CMBS as qualifying real estate interests. The SEC staff has not issued guidance with respect to whole pool Non-Agency RMBS. Accordingly, based on our own judgment and analysis of the SEC's pronouncements with respect to whole pool Agency RMBS, we may also treat Non-Agency RMBS issued with respect to an underlying pool of mortgage loans in which we hold all of the certificates issued by the pool as qualifying real estate interests. We currently treat partial pool Agency, Non-Agency RMBS and partial pool CMBS as real estate-related assets. We treat any ABS, interest rate swaps or other derivative hedging transactions we enter into as miscellaneous assets that will not exceed 20% of our total assets. We rely on guidance published by the SEC staff or on our analyses of guidance published with respect to other types of assets to determine which assets are qualifying real estate assets and real estate-related assets.
The SEC in 2011 solicited public comment on a wide range of issues relating to Section 3(c)(5)(C), including the nature of the assets that qualify for purposes of the exemption and whether mortgage REITs should be regulated in a manner similar to investment companies. There can be no assurance that the laws and regulations governing the 1940 Act status of REITs, including the guidance of the Division of Investment Management of the SEC regarding this exemption, will not change in a manner that adversely affects our operations. To the extent that the SEC or its staff publishes new or different guidance with respect to these matters, we may be required to adjust our strategy accordingly. In addition, we may be limited in our ability to make certain investments and these limitations could require us to hold assets we might wish to sell or to sell assets we might wish to hold. To the extent that the SEC staff provides more specific guidance regarding any of the matters bearing upon the exemption we rely on from the 1940 Act, we may be required to adjust our strategy accordingly. Any additional guidance from the SEC staff could provide additional flexibility to us, or it could further inhibit our ability to pursue the strategies we have chosen.
The mortgage related investments that we acquire are limited by the provisions of the 1940 Act and the rules and regulations promulgated thereunder. If the SEC determines that any of these securities are not qualifying interests in real estate or real estate-related assets, adopts a contrary interpretation with respect to these securities or otherwise believes we do not satisfy the above exceptions or changes its interpretation of the above exceptions, we could be required to restructure our activities or sell certain of our assets. We may be required at times to adopt less efficient methods of financing certain of our mortgage related investments and we may be precluded from acquiring certain types of higher yielding securities. The net effect of these factors would be to lower our net interest income. If we fail to qualify for an exemption from registration as an investment company or an exclusion from the definition of an investment company, our ability to use leverage would be substantially reduced. Further, if the SEC determined that we were an unregistered investment company, we could be subject to monetary penalties and injunctive relief in an action brought by the SEC, we would potentially be unable to enforce contracts with third parties which could seek to obtain rescission of transactions undertaken during the period for which it was established we were an unregistered investment company. If we were required to register as an investment company, it would result in a change of our financial statement requirements. Our business will be materially and adversely affected if we fail to qualify for this exemption from regulation pursuant to the 1940 Act. In addition, the loss of our 1940 Act exemption would also permit our Manager to terminate the Management Agreement, which could result in material adverse effect on our business and results of operations.        
Compliance with our 1940 Act exemption will limit our ability to invest in certain of our target assets.
At times the Manager may be limited in allocating equity to target that do not qualify as real estate or real estate related assets for purposes of the 1940 Act exemption. This limitation could adversely affect the performance of our portfolio if these non qualifying assets presents more attractive investment opportunities. Among the current target assets that are not real estate assets are ABS, non pool Agency and Non-Agency MBS, GSE Risk Sharing Securities and certain Commercial Mezzanine Loans.
The downgrade of the U.S. Government's or certain European countries' credit ratings and any future downgrades of the U.S. Government's or certain European countries' credit ratings may materially adversely affect our business, financial condition and results of operations.
On August 5, 2011, Standard & Poor's downgraded the U.S. Government's credit rating for the first time in history. More recently, concerns over economic recession, geopolitical issues, the ability of certain European sovereigns to honor their debt obligations and the exposure of certain European financial institutions to such debt, potential deflationary pressures in Europe, slowing growth in China, rapid decline in the price of oil and certain other commodities, the availability and cost of financing, the mortgage market, uncertainty related to political events such as the government spending and tax policy and uncertain real estate market have contributed to volatility and relatively low expectations for the world economy and domestic and international markets. Europe remains vulnerable to volatile financial and credit markets due to economic and political uncertainties, including the United Kingdom's decision to withdraw from the European Union, the ongoing refugee crisis, financial uncertainty in Greece and a lack of confidence in the European Union's banking system. Because FNMA and FHLMC are in conservatorship of the U.S. Government, downgrades to the U.S. Government's credit rating could impact the credit risk associated with Agency MBS and, therefore, decrease the value of the Agency MBS in which we invest. In addition, the downgrade of the U.S. Government's credit rating and the credit ratings of certain European countries has created broader financial turmoil and uncertainty, which has recently weighed heavily on the global banking system. Therefore, the downgrade of the U.S. Government's credit rating and the credit

15




ratings of certain European countries and any future downgrades of the U.S. Government's credit rating or the credit ratings of certain European countries may materially adversely affect our business, financial condition and results of operations.
Risks related to financing and hedging
Our strategy involves significant leverage, which may amplify losses.
Our current target leverage generally ranges between three to ten times the amount of our stockholders' equity (calculated in accordance with U.S. GAAP). We incur this leverage by borrowing against a substantial portion of the market value of our assets. By utilizing this leverage, we can enhance our returns. Nevertheless, this leverage, which is fundamental to our investment strategy, also creates significant risks.
As a result of our significant leverage, we may incur substantial losses if our borrowing costs increase. Our borrowing costs may increase for any of the following reasons:
short-term interest rates increase;
the market value of our securities decreases;
interest rate volatility increases; or
the availability of financing in the market decreases.
Fluctuations in interest rates could materially affect our financial results
In July 2017, the United Kingdom Financial Conduct Authority (the authority that regulates LIBOR) announced it intends to stop persuading or compelling banks to submit rates for the calculation of LIBOR after 2021. The Alternative Reference Rates Committee (“ARRC”) has proposed that the Secured Overnight Financing Rate (“SOFR”) is the rate that represents best practice as the alternative to USD-LIBOR for use in derivatives and other financial contracts that are currently indexed to USD-LIBOR. ARRC has proposed a paced market transition plan to SOFR from USD-LIBOR and organizations are currently working on industry wide and company specific transition plans as it relates to derivatives and cash markets exposed to USD-LIBOR. We have material contracts, including agreements governing certain of our indebtedness that are indexed to USD-LIBOR and are monitoring this activity and evaluating the related risks. In September 2019, the FASB proposed guidance that would help facilitate the market transition from existing reference rates to alternative rates. However, at this time, it is not possible to predict the effect of any such changes, any establishment of alternative reference rates or any other reforms to LIBOR that may be enacted in the United Kingdom or elsewhere. Uncertainty as to the nature of such potential changes, alternative reference rates or other reforms may adversely affect the trading market for LIBOR-based securities, including our material contract that are indexed to USD-LIBOR. Furthermore, we may need to renegotiate any credit agreements extending beyond 2021 that utilize LIBOR as a factor in determining the interest rate to replace LIBOR with the new standard that is established. There is currently no definitive information regarding the future utilization of LIBOR or of any particular replacement rate. As such, potential effect of any such event on our business, financial condition and results of operations cannot yet be determined.
There can be no assurance that our Manager will be able to prevent mismatches in the maturities of our assets and liabilities.
Because we employ financial leverage in funding our portfolio, mismatches in the maturities of our assets and liabilities can create risk in the need to continually renew or otherwise refinance our liabilities. Our net interest margins are dependent upon a positive spread between the returns on our asset portfolio and our overall cost of funding. Our Manager actively employs portfolio-wide and security-specific risk measurement and management processes in our daily operations. Our Manager's risk management tools include software and services licensed or purchased from third parties, in addition to proprietary systems and analytical methods developed internally. There can be no assurance that these tools and the other risk management techniques described above will protect us from asset/liability risks.
We may be subject to margin calls under our master repurchase agreements, which could result in defaults or force us to sell assets under adverse market conditions or through foreclosure.
We have entered into master repurchase agreements with various financial institutions and borrow under these master repurchase agreements to finance the acquisition of assets for our investment portfolio. Pursuant to the terms of borrowings under our master repurchase agreements, a decline in the value of the subject assets may result in our lenders initiating margin calls. A margin call means that the lender requires us to pledge additional collateral to re-establish the ratio of the value of the collateral to the amount of the borrowing. The specific collateral value to borrowing ratio that would trigger a margin call is not set in the master repurchase agreements and will not be determined until we engage in a repurchase transaction under these agreements.

16




Our fixed-rate securities generally are more susceptible to margin calls as increases in interest rates tend to have a greater negative affect on the market value of fixed-rate securities. If we are unable to satisfy margin calls, our lenders may foreclose on our collateral. The threat of or occurrence of a margin call could force us to sell our assets, either directly or through a foreclosure, under adverse market conditions. Because of the significant leverage we have, we may incur substantial losses upon the threat or occurrence of a margin call.
If a counterparty to our repurchase transactions defaults on its obligation to resell the underlying security back to us at the end of the transaction term, or if the value of the underlying security has declined as of the end of that term, or if we default on our obligations under the repurchase agreement, we will lose money on our repurchase transactions.
When we engage in repurchase transactions, we generally sell securities to lenders (repurchase agreement counterparties) and receive cash from these lenders. The lenders are obligated to resell the same securities back to us at the end of the term of the transaction. Because the cash we receive from the lender when we initially sell the securities to the lender will be less than the value of those securities (this difference is the haircut), if the lender defaults on its obligation to resell the same securities back to us we may incur a loss on the transaction equal to the amount of the haircut (assuming there was no change in the value of the securities). We would also lose money on a repurchase transaction if the value of the underlying securities has declined as of the end of the transaction term, as we would have to repurchase the securities based on their initial value but would receive securities worth less than that amount. Further, if we default on one of our obligations under a repurchase transaction, the lender can terminate the transaction and cease entering into any other repurchase transactions with us. Our inability to post adequate collateral for a margin call by the counterparty, in a time frame as short as the close of the same business day, could result in a condition of default under our repurchase agreements, thereby enabling the counterparty to liquidate the collateral pledged by us, which may have a material adverse effect on our financial position, results of operations and cash flows. Certain of our repurchase agreements contain cross-default provisions, such that if a default occurs under an agreement with any specific lender, that lender could also declare a default under other repurchase agreements or other financing or derivative contracts, if any, with such lender. Further, 16 of the counterparties to our repurchase agreements held, as of December 31, 2019, collateral valued in excess of 5% of our stockholders' equity as security for our obligations under the applicable repurchase agreements. Any losses we incur on our repurchase transactions could adversely affect our earnings and thus our cash available for distribution to our stockholders.
If a counterparty to one of our swap agreements or TBAs defaults on its obligations, we may incur losses.
If a counterparty to one of the bilateral swap agreements that we enter into or TBAs that we enter into defaults on its obligations under the agreement, we may not receive payments due under the agreement, and thus, we may lose any unrealized gain associated with the agreement. In the case of a swap agreement, the fact that such swap agreement hedged a liability means that the liability could cease to be hedged upon the default of a counterparty. Additionally, we may also risk the loss of any collateral we have pledged to secure our obligations under a bilateral swap agreement if the counterparty, or in the case of a cleared swap, if our clearing broker, becomes insolvent or files for bankruptcy.
Failure to procure adequate repurchase agreement financing, which generally have short terms, or to renew or replace repurchase agreement financing as it matures, would adversely affect our results of operations.
We use repurchase agreement financing as a strategy to increase the return on our investment portfolio. However, we may not be able to achieve our desired leverage ratio for a number of reasons, including if the following events occur:
our lenders do not make repurchase agreement financing available to us at acceptable rates;
certain of our lenders exit the repurchase market;
our lenders require that we pledge additional collateral to cover our borrowings, which we may be unable to do; or
we determine that the leverage would expose us to excessive risk.
We cannot assure you that any, or sufficient, repurchase agreement financing will be available to us on terms that are acceptable to us. In recent years, investors and financial institutions that lend in the securities repurchase market, have tightened lending standards in response to the difficulties and changed economic conditions that have materially adversely affected the MBS market. These market disruptions have been most pronounced in the Non-Agency MBS market, and the impact has also extended to Agency MBS, which has made the value of these assets unstable and relatively illiquid compared to prior periods. Any decline in their value, or perceived market uncertainty about their value, would make it more difficult for us to obtain financing on favorable terms or at all, or maintain our compliance with terms of any financing arrangements then in place.
As of December 31, 2019, we had amounts outstanding under repurchase agreements with 21 separate lenders and had repurchase agreements with 34 different lenders. Prior to entering into a lending relationship with any financial institution, our Manager does a thorough credit review of such potential lender. Notwithstanding the foregoing, a material adverse development

17




involving one or more major financial institutions or the financial markets in general, in addition to the regulatory changes, could result in our lenders reducing our access to funds available under our repurchase agreements or terminating such agreements altogether.
Furthermore, because we rely primarily on short-term borrowings, our ability to achieve our investment objectives will depend not only on our ability to borrow money in sufficient amounts and on favorable terms, but also on our ability to renew or replace on a continuous basis our maturing short-term borrowings. If we are unable to renew or replace our maturing short-term borrowings due to liquidity shortfalls in the repurchase agreement market and other short-term funding markets, changes in the regulatory environment or for any other reason, we will have to sell some or all of our assets, possibly under adverse market conditions which may have a material adverse effect on our financial position, results of operations and cash flows. In addition, the aforementioned changes to the regulatory capital requirements imposed on our lenders may significantly increase the cost of the financing that they provide to us. Our lenders also may revise their eligibility requirements for the types of assets they are willing to finance or the terms of such financings, based on, among other factors, the recent changes in the regulatory environment and their management of perceived risk, particularly with respect to assignee liability.
Our repurchase agreement financing may require us to provide additional collateral and may restrict us from leveraging our assets as fully as desired.
We use repurchase agreements to finance acquisitions of our investments. If the market value of the asset pledged or sold by us to a financing institution pursuant to a repurchase agreement declines, we may be required by the financing institution to provide additional collateral or pay down a portion of the funds advanced, but we may not have the funds available to do so, which could result in defaults. Posting additional collateral to support our credit will reduce our liquidity and limit our ability to leverage our assets, which could adversely affect our business. In the event we do not have sufficient liquidity to meet such requirements, financing institutions can accelerate repayment of our indebtedness, increase interest rates, liquidate our collateral or terminate our ability to borrow. Such a situation would likely result in a rapid deterioration of our financial condition and possibly necessitate a filing for bankruptcy protection.
On the date each month that principal payments are announced (i.e., the factor day for our Agency RMBS), the value of our Agency RMBS pledged as collateral under our repurchase agreements is reduced by the amount of the prepaid principal and, as a result, our lenders will typically initiate a margin call requiring the pledge of additional collateral or cash, in an amount equal to such prepaid principal, in order to re-establish the required ratio of borrowing to collateral value under such repurchase agreements. Accordingly, with respect to our Agency RMBS the announcement on factor day of principal prepayments is in advance of our receipt of the related scheduled payment, thereby creating a short-term receivable for us in the amount of such principal prepayments; however, under our repurchase agreements, we may receive a margin call relating to the related reduction in value of our Agency RMBS and prior to receipt of this short-term receivable, be required to post additional collateral or cash in an amount equal to the product of the advance rate of such repurchase agreement and the principal prepayment on or about factor day, which would reduce our liquidity during the period in which the short-term receivable is outstanding. As a result, in order to meet any such margin calls, we could be forced to sell assets in order to maintain liquidity. Forced sales under adverse market conditions may result in lower sales prices than ordinary market sales in the normal course of business.
Further, financial institutions providing the repurchase facilities may require us to maintain a certain amount of cash uninvested or to set aside non-levered assets sufficient to maintain a specified liquidity position which would allow us to satisfy our collateral obligations. As a result, we may not be able to leverage our assets as fully as we would choose which could reduce our return on equity. If we are unable to meet these collateral obligations, our financial condition could deteriorate rapidly.
Lenders may require us to enter into restrictive covenants relating to our operations.
When we obtain further financing, lenders could impose restrictions on us that would affect our ability to incur additional debt, our capability to make distributions to stockholders and our flexibility to determine our operating policies. Loan documents we execute may contain negative covenants that limit, among other things, our ability to repurchase stock, distribute more than a certain amount of our funds from operations, and employ leverage beyond certain amounts.
Our rights under repurchase agreements may be subject to the effects of the bankruptcy laws in the event of the bankruptcy or insolvency of us or our counterparties under the repurchase agreements.
In the event of our insolvency or bankruptcy, certain repurchase agreements may qualify for special treatment under the U.S. Bankruptcy Code, the effect of which, among other things, would be to allow the lender under the applicable repurchase agreement to avoid the automatic stay provisions of the U.S. Bankruptcy Code and to take possession of and liquidate the assets that we have pledged under their repurchase agreements. In the event of the insolvency or bankruptcy of a lender during the term of a repurchase agreement, the lender may be permitted, under applicable insolvency laws, to repudiate the contract, and our claim against the lender for damages may be treated simply as the claim of an unsecured creditor. In addition, if the lender is a broker or dealer subject to the Securities Investor Protection Act of 1970, or an insured depository institution subject to the Federal Deposit

18




Insurance Act, our ability to exercise our rights to recover our securities under a repurchase agreement or to be compensated for any damages resulting from the lender's insolvency may be further limited by those statutes. These claims would be subject to significant delay and, if and when received, may be substantially less than the damages we actually incur.
An increase in our borrowing costs relative to the interest that we receive on our portfolio investments may adversely affect our profitability and cash available for distribution to our stockholders.
As long as we earn a positive spread between interest and other income we earn on our leveraged assets and our borrowing costs, we believe that we can generally increase our profitability by using greater amounts of leverage. We cannot, however, assure you that repurchase financing will remain an efficient source of long-term financing for our assets. The amount of leverage that we use may be limited because our lenders might not make funding available to us or they may require that we provide additional collateral to secure our borrowings. If our financing strategy is not viable, we will have to find alternative forms of financing for our assets which may not be available to us on acceptable terms or at acceptable rates. In addition, in response to certain interest rate and investment environments or to changes in the market liquidity, we could adopt a strategy of reducing our leverage by selling assets or not reinvesting principal payments as MBS amortize and/or prepay, thereby decreasing the outstanding amount of our related borrowings. Such an action could reduce interest income, interest expense and net income, the extent of which would be dependent on the level of reduction in assets and liabilities as well as the sale prices for which assets were sold.
As our financings mature, we will be required either to enter into new borrowings or to sell certain of our investments. Since we rely primarily on borrowings under repurchase agreements to finance our assets, our ability to achieve our investment objectives depends on our ability to borrow funds in sufficient amounts and on acceptable terms, and on our ability to renew or replace maturing borrowings on a continuous basis. Our repurchase agreement credit lines are renewable at the discretion of our lenders and, as such, do not contain guaranteed roll-over terms. Our ability to enter into repurchase transactions in the future will depend on the market value of our assets pledged to secure the specific borrowings, the availability of acceptable financing and market liquidity and other conditions existing in the lending market at that time. If we are unable to renew or replace maturing borrowings, we could be forced to sell assets in order to maintain liquidity. Forced sales under adverse market conditions could result in lower sales prices than ordinary market sales in the normal course of business. Further, an increase in short-term interest rates at the time that we seek to enter into new borrowings would reduce the spread between our returns on our assets and the cost of our borrowings. This would adversely affect our returns on our assets, which might reduce earnings and, in turn, cash available for distribution to our stockholders.
Our investments in Residential and Commercial Whole Loans are difficult to value and are dependent upon the ability to finance, refinance and securitize such investments. The inability to do so could materially and adversely affect our liquidity and earnings and limit the cash available for distribution to our stockholders.
We may seek to finance and refinance our Residential Whole Loans and Commercial Whole Loans to generate greater value from such loan. However, there may be impediments to executing either a financing or refinancing strategy for these investments. The financing of these investments presents additional challenges because in general it is less available than repurchase financing for MBS, especially Agency CMBS and Agency RMBS, and likely to have less advantageous pricing and more onerous terms. Accordingly, there can be no assurance that we will be able to finance Whole Loans at all, let alone on terms we believe are advantageous.
We may enter into hedging transactions that could expose us to contingent liabilities in the future.
Subject to maintaining our qualification as a REIT and exemption from registration under the 1940 Act, part of our investment strategy may involve entering into economic hedging transactions that could require us to fund cash payments in certain circumstances (such as the early termination of the hedging instrument caused by an event of default or other early termination event, or the decision by a counterparty to request margin securities it is contractually owed under the terms of the hedging instrument). The amount due would be equal to the unrealized loss of the open swap positions with the respective counterparty and could also include other fees and charges. These economic losses will be reflected in our results of operations, and our ability to fund these obligations will depend on the liquidity of our assets and access to capital at the time, and the need to fund these obligations could adversely impact our financial condition.
Hedging against interest rate exposure may adversely affect our earnings, which could reduce our cash available for distribution to our stockholders.
Subject to maintaining our qualification as a REIT and exemption from registration under the 1940 Act, we may pursue various economic hedging strategies to seek to reduce our exposure to adverse changes in interest rates. Our hedging activity varies in scope based on the level and volatility of interest rates, the type of assets held and other changing market conditions. Interest rate hedging may fail to protect or could adversely affect us because, among other things:
interest rate hedging can be expensive, particularly during periods of rising and volatile interest rates;

19




available interest rate hedges may not correspond directly with the interest rate risk for which protection is sought;
due to a credit loss, the duration of the hedge may not match the duration of the related liability;
the amount of income that a REIT may earn from hedging transactions (other than hedging transactions that satisfy certain requirements of the Code or that are done through a taxable REIT subsidiary (a "TRS") to offset interest rate losses is limited by U.S. federal tax provisions governing REITs);
the value of derivatives used for hedging may be adjusted from time to time in accordance with accounting rules to reflect changes in fair value. Downward adjustments or "mark-to-market losses," would reduce our stockholders' equity;
the credit quality of the hedging counterparty owing money on the hedge may be downgraded to such an extent that it impairs our ability to sell or assign our side of the hedging transaction; and
the hedging counterparty owing money in the hedging transaction may default on its obligation to pay.
Our hedging transactions, which are intended to limit losses, may actually adversely affect our earnings, which could reduce our cash available for distribution to our stockholders.
While the majority of our interest rate swaps are traded on a regulated exchange, certain hedging instruments are traded over the counter and do not trade on regulated exchanges and, therefore, are not guaranteed by an exchange or a clearing house. In addition, over the counter instruments are more lightly regulated by U.S. and foreign governmental authorities. Consequently, there may be no requirements with respect to record keeping, financial responsibility or segregation of customer funds and positions. Furthermore, the enforceability of agreements underlying hedging transactions may depend on compliance with applicable statutory and commodity and other regulatory requirements and, depending on the identity of the counterparty, applicable international requirements. The business failure of a hedging counterparty with whom we enter into a hedging transaction which did not clear through a clearing house would most likely result in its default. Default by a party with whom we enter into a hedging transaction may result in the loss of unrealized profits and force us to cover our commitments, if any, at the then current market price. Although generally we seek to reserve the right to terminate our hedging positions, it may not always be possible to dispose of or close out a hedging position without the consent of the hedging counterparty and we may not be able to enter into an offsetting contract in order to cover our risk. There can be no assurance that a liquid secondary market will exist for any hedging instruments purchased or sold, and we may be required to maintain a position until exercise or expiration, which could result in losses.

Risks associated with our relationship with our Manager
Our Board of Directors has approved very broad investment guidelines for our Manager and does not approve each investment and financing decision made by our Manager.
Our Manager is authorized to follow very broad investment guidelines. Our Board of Directors periodically reviews our investment guidelines and our investment portfolio but does not, and is not required to review all of our proposed investments, except that an investment in a security structured or issued by another entity managed by our Manager must be approved by at least two-thirds (2/3) of our independent directors prior to such investment. In addition, in conducting periodic reviews, our Board of Directors may rely primarily on information provided to them by our Manager. Furthermore, our Manager may use complex strategies, and transactions entered into by our Manager may be costly, difficult or impossible to unwind by the time they are reviewed by our Board of Directors. Our Manager has great latitude within the broad parameters of our investment guidelines in determining the types and amounts of Agency and Non-Agency RMBS, CMBS, ABS and Whole Loan investments it may decide are attractive investments for us, which could result in investment returns that are substantially below expectations or that result in losses, which would materially and adversely affect our business operations and results. Further, decisions made and investments and financing arrangements entered into by our Manager may not fully reflect the best interests of our stockholders.
There are conflicts of interest in our relationship with our Manager that could result in decisions that are not in the best interests of our stockholders.
We are subject to conflicts of interest arising out of our relationship with our Manager. We do not have any employees. All of our executive officers and two of our directors, James W. Hirschmann III and Jennifer W. Murphy, are employees of our Manager. Our Management Agreement with our Manager was negotiated between related parties and its terms, including fees and other amounts payable, may not be as favorable to us as if it had been negotiated at arm's-length with an unaffiliated third party. In addition, the obligations of our Manager and its officers and personnel to engage in other business activities may reduce the time our Manager and its officers and personnel spend managing us.

20




We compete for investment opportunities directly with other client portfolios managed by our Manager. Clients of our Manager have investment mandates and objectives that target the same assets as us. A substantial number of client accounts managed by our Manager have exposure to RMBS, CMBS and other investments and may have similar investment mandates and objectives. While our Manager has only a limited number of client accounts investing in Whole loans, the supply of Whole Loan investments meeting the Manager's investment criteria is extremely limited. In addition, our Manager may have additional clients that compete directly with us for investment opportunities in the future. Our Manager has an investment allocation policy in place that is intended to ensure that no single client is intentionally favored over another and that trades are allocated in a fair and equitable manner. We may compete with our Manager or its other clients for investment or financing opportunities sourced by our Manager; however, we may either not be presented with the opportunity or have to compete with our Manager to acquire these investments or have access to these sources of financing. Our Manager and our executive officers may choose to allocate favorable investments to itself or to its or other clients instead of to us. Further, at times when there are turbulent conditions in the mortgage markets or distress in the credit markets or other times when we will need focused support and assistance from our Manager, our Manager's other clients will likewise require greater focus and attention, placing our Manager's resources in high demand. In such situations, we may not receive the level of support and assistance that we may receive if we were internally managed or if our Manager did not act as a manager for other entities. There is no assurance that our Manager's allocation policies that address some of the conflicts relating to our access to investment and financing sources will be adequate to address all of the conflicts that may arise.
We pay our Manager a management fee that is not tied to our performance. The management fee may not sufficiently incentivize our Manager to generate attractive risk-adjusted returns for us. This could hurt both our ability to make distributions to our stockholders and the market price of our common stock. Furthermore, the compensation payable to our Manager will increase as a result of future issuances of our equity securities, even if the issuances are dilutive to existing stockholders.
As of December 31, 2019, our Manager owned 1,383,865 shares of our common stock. To the extent our Manager elects to sell all or a portion of these shares in the future, our Manager's interests may be less aligned with our interests.
We are dependent on our Manager and its key personnel for our success.
We have no separate facilities and are completely reliant on our Manager. All of our executive officers and two of our directors, are employees of our Manager. Our Manager has significant discretion as to the implementation of our investment and operating policies and strategies. Accordingly, we believe that our success will depend to a significant extent upon the efforts, experience, diligence, skill and network of business contacts of the executive officers and key personnel of our Manager. The executive officers and key personnel of our Manager evaluate, negotiate, close and monitor our investments; therefore, our success depends on their continued service. The departure of any of the executive officers or key personnel of our Manager could have a material adverse effect on our performance. In addition, we offer no assurance that our Manager will remain our investment manager or that we will continue to have access to our Manager's principals and professionals. The term of our Management Agreement with our Manager expires on May 16, 2021, with automatic one-year renewals thereafter. If the Management Agreement is terminated and no suitable replacement is found to manage us, we may not be able to execute our business plan. Moreover, our Manager is not obligated to dedicate any of its personnel exclusively to us nor is it obligated to dedicate any specific portion of its time to our business, and none of our Manager's personnel are contractually dedicated to us under our Management Agreement with our Manager.
The Management Agreement with our Manager was not negotiated on an arm's-length basis, may not be as favorable to us as if it had been negotiated with an unaffiliated third party and may be costly and difficult to terminate.
All of our executive officers and two of our directors are employees of our Manager. Our Management Agreement with our Manager was negotiated between related parties and its terms, including fees payable, may not be as favorable to us as if it had been negotiated with an unaffiliated third party.
Termination of the Management Agreement with our Manager without cause is difficult and costly. Our independent directors review our Manager's performance and any fees payable to our Manager annually and the Management Agreement may be terminated annually upon the affirmative vote of at least two-thirds (2/3) of our independent directors based upon: (i) our Manager's unsatisfactory performance that is materially detrimental to us; or (ii) our determination that any fees payable to our Manager are not fair, subject to our Manager's right to prevent termination based on unfair fees by accepting a reduction of management fees agreed to by at least two-thirds (2/3) of our independent directors. We are required to provide our Manager 180 days prior notice of any such termination. Unless terminated for cause, we are required to pay our Manager a termination fee equal to three times the average annual management fee earned by our Manager during the prior 24-month period immediately preceding such termination, calculated as of the end of the most recently completed fiscal quarter before the date of termination. This provision increases the effective cost to us of electing not to renew, or defaulting in our obligations under, the Management Agreement, thereby adversely affecting our inclination to end our relationship with our Manager, even if we believe our Manager's performance is not satisfactory.

21




Our Manager is only contractually committed to serve us until May 16, 2021. The Management Agreement is automatically renewable for one-year terms; provided, however, that our Manager may terminate the Management Agreement annually upon 180 days prior notice. If the Management Agreement is terminated and no suitable replacement is found to manage us, we may not be able to execute our business plan.
Pursuant to the Management Agreement, our Manager does not assume any responsibility other than to render the services called for thereunder and is not responsible for any action of our Board of Directors in following or declining to follow its advice or recommendations. Our Manager maintains a contractual as opposed to a fiduciary relationship with us. Under the terms of the Management Agreement, our Manager, its officers, stockholders, members, managers, directors, personnel, any person controlling or controlled by our Manager and any person providing sub-advisory services to our Manager are not liable to us, our directors, our stockholders or any partners for acts or omissions performed in accordance with and pursuant to the Management Agreement, except because of acts constituting bad faith, willful misconduct, gross negligence, or reckless disregard of their duties under the Management Agreement. In addition, we indemnify our Manager, its officers, stockholders, members, managers, directors, personnel, any person controlling or controlled by our Manager and any person providing sub-advisory services to our Manager with respect to all expenses, losses, damages, liabilities, demands, charges and claims arising from acts of our Manager not constituting bad faith, willful misconduct, gross negligence, or reckless disregard of duties, performed in good faith in accordance with and pursuant to the Management Agreement.
Our Manager's management fee is payable regardless of our performance.
We pay our Manager a management fee regardless of the performance of our portfolio. Our Manager's entitlement to non-performance-based compensation might reduce its incentive to devote its time and effort to seeking assets that provide attractive risk-adjusted returns for our portfolio. This in turn could hurt both our ability to make distributions to our stockholders and the market price of our common stock.
Our Manager is subject to extensive regulation as an investment advisor, which could adversely affect its ability to manage our business.
Our Manager is subject to regulation as an investment advisor by various regulatory authorities that are charged with protecting the interests of its clients, including us. Instances of criminal activity and fraud by participants in the investment management industry and disclosures of trading and other abuses by participants in the financial services industry have led the U.S. government and regulators to the rules and regulations governing, and oversight of, the U.S. financial system, including the investment management industry and more aggressive enforcement of the existing laws and regulations. Our Manager could be subject to civil liability, criminal liability, or sanction, including revocation of its registration as an investment adviser, revocation of the licenses of its employees, censures, fines, or temporary suspension or permanent bar from conducting business, if it is found to have violated any of these laws or regulations. Any such liability or sanction could adversely affect its ability to manage our business. Our Manager must continually address conflicts between its interests and those of its clients, including us. In addition, the SEC and other regulators have increased their scrutiny of potential conflicts of interest. We believe our Manager has procedures and controls that are reasonably designed to address these issues. However, appropriately dealing with conflicts of interest is complex and difficult and if our Manager fails, or appears to fail, to deal appropriately with conflicts of interest, it could face litigation or regulatory proceedings or penalties, any of which could adversely affect its ability to manage our business.
Risks related to our common stock
The market price and trading volume of our common stock may vary substantially.
Our common stock is listed on the NYSE under the symbol "WMC." The stock markets, including the NYSE, have experienced significant price and volume fluctuations over the past several years. As a result, the market price of our common stock is likely to be similarly volatile, and investors in our common stock may experience a decrease in the value of their shares. Accordingly, no assurance can be given as to the ability of our stockholders to sell their common stock or the price that our stockholders may obtain for their common stock.
Some of the factors that could negatively affect the market price of our common stock include:
actual or anticipated variations in our quarterly operating results;
changes in our earnings estimates or publication of research reports about us or the real estate industry;
changes in market valuations of similar companies;
adverse market reaction to any increased indebtedness we incur in the future;

22




additions to or departures of our Manager's key personnel;
actions by our stockholders;
changes in our dividend policy or payments; and
speculation in the press or investment community.
Market factors unrelated to our performance could also negatively impact the market price of our common stock. One of the factors that investors may consider in deciding whether to buy or sell our common stock is our distribution rate as a percentage of our stock price relative to market interest rates. If market interest rates increase, prospective investors may seek alternative investments paying higher dividends or interest. As a result, interest rate fluctuations and conditions in the capital markets can affect the market value of our common stock. For instance, if interest rates rise, it is likely that the market price of our common stock will decrease as market rates on interest-bearing securities increase.
Investing in our common stock may involve a high degree of risk.
The investments that we make in accordance with our investment objectives may result in a high amount of risk when compared to alternative investment options and volatility or loss of principal. Our investments may be highly speculative and aggressive, and therefore an investment in our common stock may not be suitable for someone with lower risk tolerance.
Common stock eligible for future sale may have adverse effects on our share price.
We cannot predict the effect, if any, of future sales of our common stock, or the availability of shares for future sales, on the market price of our common stock. The market price of our common stock may decline significantly when the restrictions on resale (or lock up agreements), which may attach to future sales of our common stock, by certain of our stockholders lapse. Sales of substantial amounts of common stock or the perception that such sales could occur may adversely affect the prevailing market price for our common stock.
Also, we may issue additional shares in follow-on public offerings or private placements to make new investments or for other purposes. We are not required to offer any such shares to existing stockholders on a preemptive basis. Therefore, it may not be possible for existing stockholders to participate in such future share issuances, which may dilute the existing stockholders' interests in us.
We have not established a minimum distribution payment level and we cannot assure you of our ability to pay distributions in the future.
We intend to pay quarterly distributions and to make distributions to our stockholders in an amount such that we distribute all or substantially all of our net taxable income, calculated in accordance with the REIT requirements, each year. We have not established a minimum distribution payment level and our ability to pay distributions may be adversely affected by a number of factors, including the risk factors described herein. All distributions will be made at the discretion of our Board of Directors and will depend on our earnings, our financial condition, debt covenants, maintenance of our REIT qualification and other factors our Board of Directors may deem relevant from time to time. We believe that a change in any one of the following factors could adversely affect our results of operations and impair our ability to pay distributions to our stockholders:
the profitability of our existing investments and the investment of net proceeds of any subsequent offering;
our ability to make profitable investments;
margin calls or other expenses that reduce our cash flow;
decreases in the value of our portfolio or defaults in our asset portfolio; and
the fact that anticipated operating expense levels may not prove accurate, as actual results may vary from estimates.
We cannot assure you that we will achieve investment results that will allow us to make a specified level of cash distributions or year-to-year increases in cash distributions in the future. In addition, some of our distributions may include a return in capital.
Future offerings of debt or equity securities, which would rank senior to our common stock, may adversely affect the market price of our common stock.
If we decide to issue debt or equity securities in the future, which would rank senior to our common stock, it is likely that they will be governed by an indenture or other instrument containing covenants restricting our operating flexibility. Additionally,

23




any convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our common stock and may result in dilution to owners of our common stock. We and, indirectly, our stockholders, will bear the cost of issuing and servicing such securities. Because our decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus holders of our common stock will bear the risk of our future offerings reducing the market price of our common stock and diluting the value of their stock holdings in us. Furthermore, the compensation payable to our Manager will increase as a result of future issuances of our equity securities, including issuances upon exercise of the warrants, described below, even if the issuances are dilutive to existing stockholders.
Conversion of our convertible senior unsecured notes may dilute the ownership interest of existing stockholders, including holders who had previously converted their notes.
The Company has issued $205.0 million aggregate principal amount of 6.75% convertible senior unsecured notes. The notes mature on October 1, 2022, unless earlier converted, redeemed or repurchased by the holders pursuant to their terms, and are not redeemable by the Company except during the final three months prior to maturity.

The notes are convertible into, at the Company's election, cash, shares of the Company's common stock or a combination of both, subject to the satisfaction of certain conditions and during specified periods. The conversion rate is subject to adjustment upon the occurrence of certain specified events and the holders may require the Company to repurchase all or any portion of their notes for cash equal to 100% of the principal amount of the notes, plus accrued and unpaid interest, if the Company undergoes a fundamental change as specified in the agreement. The initial conversion rate was 83.1947 shares of common stock per $1,000 principal amount of notes and represented a conversion price of $12.02 per share of common stock.

To the extent we issue shares of our common stock upon conversion of the notes, the conversion of some or all of our notes will dilute the ownership interests of existing stockholders. Any sales in the public market of shares of our common stock issuable upon such conversion of the notes could adversely affect the prevailing market price.
Risks related to our organization and structure
Our authorized but unissued shares of common and preferred stock may prevent a change in our control.
Our amended and restated certificate of incorporation authorizes us to issue additional authorized but unissued shares of common or preferred stock. In addition, our Board of Directors may, without stockholder approval, amend our amended and restated certificate of incorporation to increase the aggregate number of our shares of stock or the number of shares of stock of any class or series that we have authority to issue and classify or reclassify any unissued shares of common or preferred stock and set the preferences, rights and other terms of the classified or reclassified shares. As a result, our Board of Directors may establish a series of shares of common or preferred stock that could delay or prevent a transaction or a change in control that might involve a premium price for our shares of common stock or otherwise be in the best interest of our stockholders.
Ownership limitations may restrict change of control or business combination opportunities in which our stockholders might receive a premium for their shares.
To maintain our qualification as a REIT, no more than 50% in value of our outstanding capital stock may be owned, directly or indirectly, by five or fewer individuals during the last half of any calendar year. "Individuals" for this purpose include natural persons, private foundations, some employee benefit plans and trusts, and some charitable trusts. To assist us in maintaining our qualification as a REIT, our amended and restated certificate of incorporation generally prohibits any person from directly or indirectly owning more than 9.8% in value or in number of shares, whichever is more restrictive, of the outstanding shares of our capital stock or more than 9.8% in value or in number of shares, whichever is more restrictive, of the outstanding shares of our common stock. This ownership limitation could have the effect of discouraging a takeover or other transaction in which holders of our common stock might receive a premium for their shares over the then prevailing market price or which holders might believe to be otherwise in their best interests.
Provisions in our amended and restated certificate of incorporation, our amended and restated bylaws and Delaware law may have the effect of preventing or hindering a change in control and adversely affecting the market price of our common stock.
Provisions in our amended and restated certificate of incorporation and our amended and restated bylaws and applicable provisions of the Delaware General Corporation Law may make it more difficult and expensive for a third party to acquire control of us even if a change of control would be beneficial to the interests of our stockholders. These provisions could discourage potential takeover attempts and could adversely affect the market price our common stock.
We may pay distributions from offering proceeds, borrowings or the sale of assets to the extent that distributions exceed earnings or cash flow from our operations.

24




We may pay distributions from offering proceeds, borrowings or the sale of assets to the extent that distributions exceed earnings or cash flow from our operations. Such distributions would reduce the amount of cash we have available for investing and other purposes and could be dilutive to our financial results. In addition, funding our distributions from our net proceeds may constitute a return of capital to our investors, which would have the effect of reducing each stockholder's basis in its shares of common stock.
Risks Related to REIT Status
If we do not qualify as a REIT or fail to remain qualified as a REIT, we will be subject to U.S. federal income tax as a regular corporation and could face a substantial tax liability, which would reduce the amount of cash available for distribution to our stockholders.
We believe we have operated and intend to continue to operate in a manner that allows us to qualify as a REIT. Our qualification as a REIT depends on our satisfaction of certain asset, income, organizational, distribution, stockholder ownership and other requirements on a continuing basis. Our ability to satisfy the asset tests depends upon our analysis of the characterization and fair market values of our assets, some of which are not susceptible to a precise determination, and for which we will not obtain independent appraisals. Our compliance with the annual REIT income and quarterly asset requirements also depends upon our ability to successfully manage the composition of our income and assets on an ongoing basis. Accordingly, there can be no assurance that the IRS will not contend that our interests in our subsidiaries or in securities of other issuers will not cause a violation of the REIT requirements.
If we were to fail to qualify as a REIT in any taxable year, and we do not qualify for certain statutory relief provisions, we would be subject to U.S. federal income tax, on our taxable income at regular corporate rates, and dividends paid to our stockholders would not be deductible by us in computing our taxable income. Any resulting corporate tax liability could be substantial and would reduce the amount of cash available for distribution to our stockholders, which in turn could have an adverse impact on the value of our common stock. Unless we were entitled to relief under certain Code provisions, we also would be disqualified from taxation as a REIT for the four taxable years following the year in which we failed to qualify as a REIT.
Dividends payable by REITs do not qualify for the reduced tax rates available for some dividends.
The maximum tax rate applicable to income from "qualified dividends" payable to U.S. stockholders that are individuals, trusts and estates is currently 20%, exclusive of the 3.8% investment tax surcharge. Dividends payable by REITs, however, generally are not eligible for the qualified dividend reduced rates. Stockholders that are individuals, trusts or estates generally may deduct 20% of the aggregate amount of ordinary dividends distributed by us, subject to certain limitations for taxable years beginning after December 31, 2017 and before January 1, 2026. While the qualified dividend rules do not adversely affect the taxation of REITs or dividends payable by REITs, the more favorable rates applicable to regular corporate qualified dividends could cause investors who are individuals, trusts and estates to perceive investments in REITs to be relatively less attractive than investments in the stocks of non-REIT corporations that pay dividends, which could adversely affect the value of the stock of REITs, including our common stock.
REIT distribution requirements could adversely affect our ability to execute our business plan.
We generally must distribute annually at least 90% of our net taxable income, determined without regard to the dividends paid deduction and excluding net capital gains, in order for U.S. federal corporate income tax not to apply to earnings that we distribute. To the extent that we satisfy this distribution requirement, but distribute less than 100% of our REIT taxable income, we will be subject to U.S. federal corporate income tax on our undistributed REIT taxable income. In addition, we will be subject to a nondeductible 4% excise tax if the actual amount that we pay out to our stockholders in a calendar year is less than a minimum amount specified under U.S. federal tax laws. We intend to continue to make distributions to our stockholders to comply with the REIT requirements of the Code and avoid corporate income tax and the 4% annual excise tax.
From time to time, we may generate taxable income greater than our income for financial reporting purposes prepared in accordance with U.S. GAAP, or differences in timing between the recognition of taxable income and the actual receipt of cash may occur. For example, the Code limits our ability to use capital losses to offset ordinary income, thereby requiring us to distribute such ordinary income. If we do not have other funds available in these situations we could be required to borrow funds on unfavorable terms, sell investments at disadvantageous prices or distribute amounts that would otherwise be invested in future acquisitions to make distributions sufficient to enable us to pay out enough of our taxable income to satisfy the REIT distribution requirement and to avoid corporate income tax and the nondeductible 4% excise tax in a particular year. These alternatives could increase our costs or reduce our equity. Thus, compliance with the REIT requirements may hinder our ability to grow, which could adversely affect the value of our common stock.
Even if we remain qualified as a REIT, we may face other tax liabilities that reduce our cash flow.

25




Even if we remain qualified for taxation as a REIT, we may be subject to certain U.S. federal, state and local taxes on our income and assets, including taxes on any undistributed income, tax on income from some activities conducted as a result of a foreclosure, excise taxes, state or local income, property and transfer taxes, such as mortgage recording taxes, and other taxes. In addition, to meet the REIT qualification requirements, prevent the recognition of certain types of non-cash income, and to avert the imposition of a 100% tax that applies to certain gains derived by a REIT from dealer property or inventory, we may hold some of our assets through TRSs or other consolidated entities that will be subject to corporate-level income tax at regular corporate rates. We may also incur a 100% excise tax on transactions with a TRS if they are not conducted on an arm's-length basis. The payment of any of these taxes would decrease cash available for distribution to our stockholders.
Complying with REIT requirements may cause us to liquidate or forgo otherwise attractive opportunities.
To qualify as a REIT, we must ensure that at the end of each calendar quarter, at least 75% of the value of our assets consists of cash, cash items, government securities and qualified real estate assets, including certain mortgage loans and securities. The remainder of our investments in securities (other than government securities, qualified real estate assets and securities issued by a TRS) generally cannot include more than 10% of the outstanding voting securities of any one issuer or more than 10% of the total value of the outstanding securities of any one issuer. In addition, in general, no more than 5% of the value of our total assets (other than government securities, qualified real estate assets and securities issued by a TRS) can consist of the securities of any one issuer, and no more than 20% of the value of our total assets can be represented by securities of one or more TRSs. If we fail to comply with these requirements at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain statutory relief provisions to avoid losing our REIT qualification and suffering adverse tax consequences. As a result, we may be required to liquidate otherwise attractive investments from our investment portfolio. These actions could have the effect of reducing our income and amounts available for distribution to our stockholders.
In addition to the asset tests set forth above, to qualify as a REIT we must continually satisfy tests concerning, among other things, the sources of our income, the nature and diversification of our assets, the amounts we distribute to our stockholders and the ownership of our stock. We may be required to make distributions to stockholders at disadvantageous times or when we do not have funds readily available for distribution and may be unable to pursue investments that would be otherwise advantageous to us in order to satisfy the source-of-income or asset-diversification requirements for qualifying as a REIT. Thus, compliance with the REIT requirements may hinder our ability to make and, in certain cases, to maintain ownership of, certain attractive investments.
We may be required to report taxable income for certain investments in excess of the economic income we ultimately realize from them.
We have acquired and may acquire in the future mortgage-backed securities and other portfolio instruments in the secondary market for less than their face amount. In addition, pursuant to our ownership of certain mortgage-backed securities, we may be treated as holding certain debt instruments acquired in the secondary market for less than their face amount. The discount at which such securities or debt instruments are acquired may reflect doubts about their ultimate collectability rather than current market interest rates. The amount of such discount will nevertheless generally be treated as "market discount" for U.S. federal income tax purposes. Under general tax rules, accrued market discount is reported as income when, and to the extent that, any payment of principal of the mortgage-backed security or debt instrument is made. If we collect less on the mortgage-backed security or debt instrument than our purchase price plus the market discount we had previously reported as income, we may not be able to benefit from any offsetting capital loss deductions to the extent we do not have offsetting capital gains.
In addition, pursuant to our ownership of certain mortgage-backed securities or debt instruments, we may be treated as holding distressed debt investments that are subsequently modified by agreement with the borrower. If the amendments to the outstanding debt are "significant modifications" under applicable Treasury regulations, the modified debt may be considered to have been reissued to us at a gain in a debt-for-debt exchange with the borrower. In that event, we may be required to recognize taxable gain to the extent the principal amount of the modified debt exceeds our adjusted tax basis in the unmodified debt, even if the value of the debt or the payment expectations have not changed.
Moreover, some of the mortgage-backed securities or debt instruments that we acquire may have been issued with original issue discount. Under general tax rules, we are required to report such original issue discount based on a constant yield method and will be taxed based on the assumption that all future projected payments due on such mortgage-backed securities will be made. If such mortgage-backed securities turn out not to be fully collectable, an offsetting loss deduction will become available only in the later year that uncollectability is provable.
Finally, in the event that mortgage-backed securities or any debt instruments we are treated as holding pursuant to our investments in mortgage-backed securities are delinquent as to mandatory principal and interest payments, we may nonetheless be required to continue to recognize the unpaid interest as taxable income as it accrues, despite doubt as to its ultimate collectability. Similarly, we may be required to accrue interest income with respect to subordinate mortgage-backed securities at the stated rate

26




regardless of whether corresponding cash payments are received or are ultimately collectable. In each case, while we would in general ultimately have an offsetting loss deduction available to us when such interest was determined to be uncollectable, the utility of that deduction could depend on our having taxable income in that later year or thereafter.
Certain apportionment rules may affect our ability to comply with the REIT asset and gross income tests.
The Code provides that a regular or a residual interest in a real estate mortgage investment conduit, or REMIC, is generally treated as a real estate asset for the purpose of the REIT asset tests, and any amount includible in our gross income with respect to such an interest is generally treated as interest on an obligation secured by a mortgage on real property for the purpose of the REIT gross income tests. If, however, less than 95% of the assets of a REMIC in which we hold an interest consist of real estate assets (determined as if we held such assets), we will be treated as holding our proportionate share of the assets of the REMIC for the purpose of the REIT asset tests and receiving directly our proportionate share of the income of the REMIC for the purpose of determining the amount of income from the REMIC that is treated as interest on an obligation secured by a mortgage on real property.
The "taxable mortgage pool" rules may increase the taxes that we or our stockholders may incur, and may limit the manner in which we effect future securitizations.
Securitizations could result in the creation of taxable mortgage pools for U.S. federal income tax purposes. As a REIT, so long as we own 100% of the equity interests in a taxable mortgage pool, we generally would not be adversely affected by the characterization of the securitization as a taxable mortgage pool. Certain categories of stockholders, however, such as foreign stockholders eligible for treaty or other benefits, stockholders with net operating losses, and certain tax-exempt stockholders that are subject to unrelated business income tax, could be subject to increased taxes on a portion of their dividend income from us that is attributable to the taxable mortgage pool. In addition, to the extent that our stock is owned by tax-exempt "disqualified organizations," such as certain government-related entities and charitable remainder trusts that are not subject to tax on unrelated business income, we may incur a corporate level tax on a portion of our income from the taxable mortgage pool. In that case, we may reduce the amount of our distributions to any disqualified organization whose stock ownership gave rise to the tax. Moreover, we would be precluded from selling equity interests in these securitizations to outside investors, or selling any debt securities issued in connection with these securitizations that might be considered to be equity interests for tax purposes. These limitations may prevent us from using certain techniques to maximize our returns from securitization transactions.
Our ability to invest in and dispose of "to be announced" securities could be limited by our election to be subject to tax as a REIT.
We may purchase Agency RMBS through "to-be-announced" forward contracts, or TBAs. In certain instances, rather than take delivery of the Agency RMBS subject to a TBA, we may dispose of the TBA through a dollar roll transaction in which we agree to purchase similar securities in the future at a predetermined price or otherwise, which may result in the recognition of income or gains. We account for dollar roll transactions as purchases and sales of securities. The law is unclear regarding whether TBAs will be qualifying assets for the 75% asset test and whether income and gains from dispositions of TBAs will be qualifying income for the 75% gross income test. Accordingly, our ability to purchase Agency RMBS through TBAs and to dispose of TBAs, through dollar roll transactions or otherwise, could be limited.
The failure of securities subject to repurchase agreements to qualify as real estate assets could adversely affect our ability to qualify as a REIT.
We enter into financing arrangements that are structured as sale and repurchase agreements pursuant to which we nominally sell certain of our securities to a counterparty and simultaneously enter into an agreement to repurchase these securities at a later date in exchange for a purchase price. Economically, these agreements are financings which are secured by the securities sold pursuant thereto. We believe that we will be treated for REIT asset and income test purposes as the owner of the securities that are the subject of any such sale and repurchase agreement notwithstanding that such agreement may transfer record ownership of the securities to the counterparty during the term of the agreement. It is possible, however, that the IRS could assert that we did not own the securities during the term of the sale and repurchase agreement, in which case we could fail to qualify as a REIT.
Liquidation of assets may jeopardize our REIT qualification or create additional tax liability for us.
To continue to qualify as a REIT, we must comply with requirements regarding the composition of our assets and our sources of income. If we are compelled to liquidate our investments to repay obligations to our lenders, we may be unable to comply with these requirements, ultimately jeopardizing our qualification as a REIT, or we may be subject to a 100% tax on any resulting gain if we sell assets that are treated as dealer property or inventory.
Complying with REIT requirements may limit our ability to hedge effectively and may cause us to incur tax liabilities.

27




The REIT provisions of the Code substantially limit our ability to hedge our assets and liabilities. Any income from a hedging transaction we enter into to manage risk of interest rate changes with respect to borrowings made or to be made to acquire or carry real estate assets does not constitute "gross income" for purposes of the 75% or 95% gross income tests, provided that certain identification requirements are met. To the extent that we fail to properly identify such transactions as hedges, or enter into other types of hedging transactions, the income from those transactions is likely to be treated as non-qualifying income for purposes of both of the gross income tests. As a result of these rules, we limit our use of advantageous hedging techniques, and we may implement those hedges through a domestic TRS. This could increase the cost of our hedging activities because our TRS would be subject to tax on gains or expose us to greater risks associated with changes in interest rates than we would otherwise want to bear. In addition, losses in our TRS will generally not provide any tax benefit, except for being carried forward against future taxable income in the TRS.
Qualifying as a REIT involves highly technical and complex provisions of the Code.
Qualification as a REIT involves the application of highly technical and complex Code provisions for which only limited judicial and administrative authorities exist. Even a technical or inadvertent violation could jeopardize our REIT qualification. Our qualification as a REIT will depend on our satisfaction of certain asset, income, organizational, distribution, stockholder ownership and other requirements on a continuing basis. In addition, our ability to satisfy the requirements to qualify as a REIT depends in part on the actions of third parties over which we have no control or only limited influence.
New legislation or administrative or judicial action, in each instance potentially with retroactive effect, could make it more difficult or impossible for us to qualify as a REIT
The U.S. federal income tax treatment of REITs may be modified, possibly with retroactive effect, by legislative, judicial or administrative action at any time, which could affect the U.S. federal income tax treatment of an investment in us. The U.S. federal income tax rules dealing with REITs constantly are under review by persons involved in the legislative process, the IRS and the U.S. Treasury Department, which results in statutory changes as well as frequent revisions to regulations and interpretations. Revisions in U.S. federal tax laws and interpretations thereof could affect or cause us to change our investments and commitments and affect the tax considerations of an investment in us.

In order to maintain our qualification as a REIT, we must make annual distributions to our stockholders of at least 90% of our taxable income (not including net capital gains). We have adopted a policy of paying regular quarterly dividends on our common stock. Refer to Note 12- "Stockholders' Equity" to our Consolidated Financial Statements included in Item 8 of this annual report on Form 10-K for details on the tax characterization of our dividend.
A combination of cash and stock dividends has been paid on our common stock since our initial public offering. Dividends are declared at the discretion of the Board of Directors and depend on actual and anticipated cash from operations, our financial condition, capital requirements, the annual distribution requirements under the REIT provisions of the Internal Revenue Code and other factors the Board of Directors may consider relevant.
As of March 3, 2020, we had 6 registered holders of our common stock and 53,523,876 shares outstanding.
Securities Authorized for Issuance Under Equity Compensation Plans
In conjunction with our IPO and concurrent private placement, our Board of Directors approved the Western Asset Mortgage Capital Corporation Equity Plan (the "Equity Plan") and the Western Asset Manager Equity Plan (the "Manager Equity Plan" and collectively the "Equity Incentive Plans"). For further details, see Note 11- "Share-Based Payments" to the Consolidated Financial Statements included under Item 8 in this Form 10-K.

Stockholder Return Performance
The following graph is a comparison of the cumulative total stockholder return on the Company's common stock, the Standard & Poor's 500 Index (the "S&P 500 Index"), the Russell 2000 Index (the "Russell 2000") and the FTSE NAREIT Mortgage REITs Index (the "FTSE Mortgage REIT"), a peer group index for a five-year period from December 31, 2014 to December 31, 2019, and accordingly does not take into account the dividend the Company declared on December 19, 2019 and paid on January 24, 2020. The graph assumes that $100 was invested on December 31, 2014 in the Company's common stock, the S&P 500 Index, the Russell 2000 and the FTSE Mortgage REIT and that all dividends were reinvested without the payment of any commissions. There can be no assurance that the performance of the Company's shares will continue in line with the same or similar trends depicted in the graph below.

ITEM 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion provides the reader a narrative from the perspective of management and should be read in conjunction with our consolidated financial statements and related notes included in Item 8, "Financial Statements and Supplementary Data" of this annual report on Form 10-K.
Overview
The size and composition of our portfolio depend on investment strategies implemented by our Manager, the accessibility to capital and overall market conditions, including availability of attractively priced target assets and financing. Our objective is to provide an attractive risk adjusted return to our stockholders over the long term. Our Manager has built a diversified portfolio of our target assets to better enable us to deliver attractive returns through market cycles. Our portfolio is mainly comprised of Agency CMBS, Non-Agency CMBS, Residential Whole loans and Commercial Loans. To a lesser extent, we have investments in Agency RMBS, Residential Bridge Loans, Non-Agency RMBS, GSE Risk Sharing Securities and ABS investments secured by a portfolio of private student loans. In addition, our holdings include four securitized commercial loans from the three consolidated CMBS VIEs.
We use leverage as part of our business strategy in order to increase potential returns to our stockholders. We accomplish this by borrowing against existing investments primarily through repurchase agreements. We may also change our financing strategy and leverage without the consent of our stockholders.
We operate and elected to be taxed as a REIT, commencing with our taxable year ended December 31, 2012. We generally will not be subject to U.S. federal income taxes on our taxable income to the extent that we annually distribute, in accordance with the REIT regulations, all of our net taxable income to stockholders and maintain our intended qualification as a REIT. Certain of our non-qualifying investments were held in our taxable REIT subsidiary or "TRS." Net income generated in our TRS is taxable and subject to federal, state and local income tax at the applicable corporate tax rates.
We also intend to operate our business in a manner that will permit us to maintain our exemption from registration under the 1940 Act.
Factors Impacting Our Operating Results
Our business is affected by general U.S. residential and commercial real estate fundamentals and the overall U.S. and international economic environment. In particular, our strategy is influenced by the specific characteristics of these markets, including, but not limited to, interest rate levels and credit spreads.

Our operating results can be affected by a number of factors and primarily depend on, among other things, the size of our investment portfolio, our net interest income, changes in the market value of our investments, derivative instruments and to a lesser extent realized gains and losses on the sale of our investments and termination of our derivative instruments. Our overall performance is also impacted by the supply and demand for our target assets in the market, the terms and availability of financing for such assets, general economic conditions, the impact of U.S Government actions that affect the real estate and mortgage sectors, and the unanticipated credit events experienced by borrowers whose loans are included in our MBS, as well as our Residential Whole Loans, Residential Bridge Loan and Commercial Loan borrowers.
 
Our net interest income, which includes the amortization of purchase premiums and accretion of discounts, will vary primarily as a result of changes in interest rates, defaults and loss severity rates, borrowing costs, and prepayment speeds on our MBS and other Target Assets (as defined herein) investments.  Similarly, the overall value of our investment portfolio will be impacted by these factors as well as changes in the value of residential and commercial real estate and continuing regulatory changes.

See the Item 1A. "Risk Factors" in this annual report on Form 10-K for additional factors that may impact our operating results.
Recent Market Conditions
Our business is affected by general U.S. residential real estate fundamentals, domestic and foreign commercial real estate fundamentals and the overall U.S. and international economic environment. In particular, our strategy is influenced by the specific characteristics of these markets, including, but not limited to, prepayment rates and interest rate levels. We expect the results of our operations to be affected by various factors, many of which are beyond our control.


32




Our Manager's outlook for 2020, is as follows; i) Coronavirus will cause growth setbacks in the global recovery . ii) U.S. and global inflation will continue to be subdued, iii) sustained monetary policy accommodation by the Federal Reserve and European Central Bank suggests "low for long", and iv) spread products should outperform government bonds.
Against this backdrop, we remain constructive on housing fundamentals and expect modest home price growth over the coming years. Credit underwriting standards are historically high, making the quality of new loan production strong. We remain positive on the credit risk of GSEs (Fannie Mae and Freddie Mac) and recently issued non-agency loans as well as re-performing loans and securities. We also remain constructive on the CMBS market, due to broadly positive commercial real estate fundamentals and a favorable economic outlook. Here, we are positive on short-duration, well-structured single-borrower securitizations and loans; in conduit deals we see better value in AAA rated bonds.
During the fourth quarter of 2019, the Federal Reserve continued monetary easing, reducing the fed funds rate a quarter point in October 2019. They also significantly increased liquidity in the repurchase agreement market through its Open Market Operations. The yield curve steepened during the quarter, with 2-year Treasury yields declining five basis points and 10-year yields increasing 25 basis points. We saw credit spreads and spreads on Agency MBS tighten. Although there was a modest benefit from declining interest rates, the spread widening on our Agency CMBS portfolio overshadowed this benefit resulting in a slight decline in our book value of 0.5%.
    
    
    
    
Critical Accounting Policies
The consolidated financial statements include our accounts, those of our consolidated wholly-owned TRS and certain variable interest entities (“VIEs”) in which we are the primary beneficiary.  All intercompany amounts have been eliminated in consolidation.  In accordance with GAAP, our consolidated financial statements require the use of estimates and assumptions that involve the exercise of judgment and use of assumptions as to future uncertainties.  In accordance with SEC guidance, the following discussion addresses the accounting policies that we currently apply. Our most critical accounting policies will involve decisions and assessments that could affect our reported assets and liabilities, as well as our reported revenues and expenses. We believe that all of the decisions and assessments upon which our consolidated financial statements have been based were reasonable at the time made and based upon information available to us at that time. For a review of recent accounting pronouncements that may impact our results of operations, refer Note 2 - “Summary of Significant Accounting Policies” contained in this annual report on Form 10-K.
Valuation of Financial Instruments
 
We disclose the fair value of our financial instruments according to a fair value hierarchy (Levels I, II, and III, as defined below). ASC 820 "Fair Value Measurements and Disclosures" establishes a framework for measuring fair value and expands financial statement disclosure requirements for fair value measurements. ASC 820 further specifies a hierarchy of valuation techniques, which is based on whether the inputs into the valuation technique are observable or unobservable. The hierarchy is as follows:
Level I — Quoted prices in active markets for identical assets or liabilities.
 
Level II — Quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
 
Level III — Prices are determined using significant unobservable inputs. In situations where quoted prices or observable inputs are unavailable, for example, when there is little or no market activity for an investment at the end of the period, unobservable inputs may be used.
 
The level in the fair value hierarchy within which a fair value measurement in its entirety falls is based on the lowest level input that is significant to the fair value measurement in its entirety. Transfers between levels are determined by us at the end of the reporting period.

Mortgage-Backed Securities and Other Securities

Our mortgage-backed securities and other securities portfolio primarily consists of Agency RMBS, Non-Agency RMBS, Agency CMBS, Non-Agency CMBS, ABS and other real estate related assets. These investments are recorded in accordance with

33




ASC 320, “Investments - Debt and Equity Securities,” ASC 325-40, “Beneficial Interests in Securitized Financial Assets” or ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” We have chosen to make a fair value election pursuant to ASC 825, “Financial Instruments” for our mortgage-backed securities and other securities portfolio. Electing the fair value option allows us to record changes in fair value in the Consolidated Statements of Operations as a component of “Unrealized gain (loss), net.”

If we purchase securities with evidence of credit deterioration, we will analyze to determine if the guidance found in ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality” is applicable.

We evaluate securities for other-than-temporary impairment (“OTTI”) on at least a quarterly basis. The determination of whether a security is other-than-temporarily impaired involves judgments, estimates and assumptions based on subjective and objective factors. As a result, the timing and amount of an OTTI constitutes an accounting estimate that may change materially over time.

When the fair value of an investment security is less than its amortized cost at the balance sheet date, the security is considered impaired, and the impairment is designated as either “temporary” or “other-than-temporary.” When a security is impaired, an OTTI is considered to have occurred if (i) if we intend to sell the security (i.e., a decision has been made as of the reporting date) or (ii) it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis. If we intend to sell the security or if it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis, the entire amount of the impairment loss, if any, is recognized in earnings as OTTI and the cost basis of the security is adjusted to its fair value. Additionally, for securities accounted for under ASC 325-40 an OTTI is deemed to have occurred when there is an adverse change in the expected cash flows to be received and the fair value of the security is less than its carrying amount. In determining whether an adverse change in cash flows occurred, the present value of the remaining cash flows, as estimated at the initial transaction date (or the last date previously revised), is compared to the present value of the expected cash flows at the current reporting date. The estimated cash flows reflect those a “market participant” would use and are discounted at a rate equal to the current yield used to accrete interest income. Any resulting OTTI adjustments are reflected in “Other than temporary impairment” in our Consolidated Statements of Operations.

Increases in interest income may be recognized on a security on which we have previously recorded an OTTI charge if the cash flow of such security subsequently improves.

In addition, unrealized losses on our Agency securities, with explicit guarantee of principal and interest by the governmental sponsored entity ("GSE"), are not credit losses but rather were due to changes in interest rates and prepayment expectations. These securities would not be considered other than temporarily impaired provided we did not intend to sell the security.

Residential Whole Loans

Investments in Residential Whole Loans are recorded in accordance with ASC 310-20, "Nonrefundable Fees and Other Costs." We have chosen to make the fair value election pursuant to ASC 825 for our entire Residential Whole-Loan portfolio. Residential Whole Loans are recorded at fair value with periodic changes in fair market value being recorded in earnings as a component of "Unrealized gain (loss), net." All other costs incurred in connection with acquiring Residential Whole Loans or committing to purchase these loans are charged to expense as incurred.

On a quarterly basis, we evaluate the collectability of both interest and principal of each loan, if circumstances warrant, to determine whether such loan is impaired. A loan is impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the existing contractual terms. When a loan is impaired, we do not record an allowance for loan loss as we have elected the fair value option. However, income recognition is suspended for loans at the earlier of the date at which payments become 90-days past due or when, in the opinion of management, a full recovery of income and principal becomes doubtful. When the ultimate collectability of the principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the principal of an impaired loan is not in doubt, contractual interest is recorded as interest income when received, under the cash basis method until an accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. A loan is written off when it is no longer realizable and/or legally discharged.

Residential Bridge Loans

For the Bridge Loans acquired prior to October 25, 2017, we did not elect the fair value option pursuant to ASC 825 and accordingly these loans are recorded at their principal amount outstanding, net of any premium or discount in the Consolidated

34




Balance Sheets. Commencing with purchases subsequent to October 25, 2017, we decided to elect the fair value option pursuant to ASC 825 to be consistent with the accounting of our other investments, which are all carried at fair value. These loans are recorded at fair value with periodic changes in fair market value being recorded in earnings as a component of "Unrealized gain (loss), net". All other costs incurred in connection with acquiring the Residential Bridge Loans or committing to purchase these loans are charged to expense as incurred.

A loan is impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the existing contractual terms. We evaluate each of Residential Bridge Loans on a quarterly basis. These loans are individually specific as they relate to the borrower, collateral type, interest rate, LTV and term as well as geographic location. We evaluate the collectability of both principal and interest of each loan. When a loan is impaired, the impairment is then measured based on fair value of the collateral, since these loans are collateral dependent. Upon measurement of impairment, we record an allowance to reduce the carrying value of the loan with a corresponding charge to net income for those loans that we did not elect the fair value option. Significant judgments are required in determining impairment, including assumptions regarding the value of the loan, the value of the underlying collateral and other provisions such as guarantees. We will not record an allowance for loan loss for the Residential Bridge Loans that Company has elected the fair value option.

Income recognition is suspended for loans at the earlier of the date at which payments become 90-days past due or when, in the opinion of management, a full recovery of income and principal becomes doubtful. When the ultimate collectability of the principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the principal of an impaired loan is not in doubt, contractual interest is recorded as interest income when received, under the cash basis method until an accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. A loan is written off when it is no longer realizable and/or it is legally discharged.

Securitized Commercial Loans

Securitized commercial loans are comprised of commercial loans of consolidated variable interest entities which were sponsored by third parties. These loans are recorded in accordance with ASC 310-20, "Nonrefundable Fees and Other Costs." We have chosen to make the fair value election pursuant to ASC 825. Accordingly, these loans are recorded at fair value with periodic changes in fair value being recorded in earnings as a component of "Unrealized gain (loss), net."

The securitized commercial loans are typically collateralized by commercial real estate. As a result, we regularly evaluate the extent and impact of any credit migration associated with the performance and/or value of the underlying collateral property as well as the financial and operating capability of the borrower on a loan by loan basis. On a quarterly basis, we evaluate the collectability of both interest and principal of each loan, if circumstances warrant, to determine whether such loan is impaired. A loan is impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the existing contractual terms. When a loan is impaired, we do not record an allowance for loan loss as we have elected the fair value option.  However, income recognition is suspended for loans at the earlier of the date at which payments become 90-days past due or when, in the opinion of management, a full recovery of income and principal becomes doubtful. When the ultimate collectability of the principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the principal of an impaired loan is not in doubt, contractual interest is recorded as interest income when received, under the cash basis method until an accrual is resumed. Interest income accrual is resumed when the loan becomes contractually current and performance is demonstrated. A loan is written off when it is no longer realizable and/or legally discharged.

Commercial Loans

Investments in Commercial Loans, which are comprised of commercial mortgage loans and commercial mezzanine loans, are recorded in accordance with ASC 310-20, "Nonrefundable Fees and Other Costs." We have chosen to make the fair value election pursuant to ASC 825 for our Commercial Loan portfolio. Accordingly, these loans are recorded at fair value with periodic changes in fair value being recorded in earnings as a component of "Unrealized gain (loss), net." All other costs incurred in connection with acquiring the Commercial Loans or committing to purchase these loans are charged to expense as incurred.

Our loans are typically collateralized by commercial real estate. As a result, we regularly evaluate the extent and impact of any credit migration associated with the performance and or value of the underlying collateral property as well as the financial and operating capability of the borrower on a loan by loan basis. On a quarterly basis, we evaluate the collectability of both interest and principal of each loan, if circumstances warrant, to determine whether such loan is impaired. A loan is impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the existing contractual terms. When a loan is impaired, we do not record an allowance for loan loss as we have elected the fair value option.  However, income recognition is suspended for loans at the earlier of the date at which payments become 90-days past due or when,

35




in the opinion of management, a full recovery of income and principal becomes doubtful. When the ultimate collectability of the principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. When the ultimate collectability of the principal of an impaired loan is not in doubt, contractual interest is recorded as interest income when received, under the cash basis method until an accrual is resumed. Interest income accrual is resumed when the loan becomes contractually current and performance is demonstrated to be resumed. A loan is written off when it is no longer realizable and/or legally discharged.
 
Interest Income Recognition
 
Agency MBS, Non-Agency MBS and other securities, excluding Interest-Only Strips, rated AA and higher at the time of purchase
 
Interest income on mortgage-backed and other securities is accrued based on the respective outstanding principal balances and corresponding contractual terms. We record interest income in accordance with ASC subtopic 835-30 "Imputation of Interest," using the effective interest method. As such premiums and discounts associated with Agency MBS, Non-Agency MBS and other securities, excluding Interest-Only Strips, rated AA and higher at the time of purchase, are amortized into interest income over the estimated life of such securities. Adjustments to premium and discount amortization are made for actual prepayment activity.  We estimate prepayments at least quarterly for our securities and, as a result, if the projected prepayment speed increases, we will accelerate the rate of amortization on premiums or discounts and make a retrospective adjustment to historical amortization. Alternatively, if projected prepayment speeds decrease, we will reduce the rate of amortization on the premiums or discounts and make a retrospective adjustment to historical amortization.
 
Non-Agency MBS and other securities that are rated below AA at the time of purchase and Interest-Only Strips that are not classified as derivatives
 
Interest income on Non-Agency MBS and other securities that are rated below AA at the time of purchase and Interest-Only Strips that are not classified as derivatives are also recognized in accordance with ASC 835, using the effective yield method.  The effective yield on these securities is based on the projected cash flows from each security, which is estimated based on our observation of the then current information and events, where applicable, and will include assumptions related to interest rates, prepayment rates and the timing and amount of credit losses.  On at least a quarterly basis, we review and, if appropriate, make adjustments to our cash flow projections based on input and analysis received from external sources, internal models, and our judgment about interest rates, prepayment rates, the timing and amount of credit losses, and other factors. Changes in cash flows from those originally projected, or from those estimated at the last evaluation, may result in a prospective change in the yield/interest income recognized on such securities. Actual maturities of the securities are affected by the contractual lives of the underlying collateral, periodic payments of scheduled principal, and prepayments of principal. Therefore, actual maturities of the securities will generally be shorter than stated contractual maturities.
 
Based on the projected cash flow of such securities purchased at a discount to par value, we may designate a portion of such purchase discount as credit protection against future credit losses and, therefore, not accrete such amount into interest income.  The amount designated as credit discount may be adjusted over time, based on the actual performance of the security, its underlying collateral, actual and projected cash flow from such collateral, economic conditions and other factors. If the performance of a security with a credit discount is more favorable than forecasted, a portion of the amount designated as credit discount may be accreted into interest income prospectively.

Loan Portfolio
 
Interest income on our residential loan portfolio and commercial loan portfolio is recorded using the effective interest method based on the contractual payment terms of the loan. Any premium amortization or discount accretion will be reflected as a component of "Interest income" in our Consolidated Statements of Operations.
 
Variable Interest Entities (“VIEs”)
 
VIEs are defined as entities that by design either lack sufficient equity for the entity to finance its activities without additional subordinated financial support or are unable to direct the entity’s activities or are not exposed to the entity’s losses or entitled to its residual returns. We evaluate all of our interests in VIEs for consolidation. When the interests are determined to be variable interests, we assess whether we are deemed the primary beneficiary. The primary beneficiary of a VIE is determined to be the party that has both the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance and the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE.
 

36




To assess whether we have the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, we consider all facts and circumstances, including our role in establishing the VIE and our ongoing rights and responsibilities. This assessment includes first, identifying the activities that most significantly impact the VIE’s economic performance; and second, identifying which party, if any, has power over those activities. In general, the parties that make the most significant decisions affecting the VIE or have the right to unilaterally remove those decision makers is deemed to have the power to direct the activities of a VIE.

To assess whether we have the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, we consider all of our economic interests. This assessment requires that we apply judgment in determining whether these interests, in the aggregate, are considered potentially significant to the VIE. Factors considered in assessing significance include: the design of the VIE, including its capitalization structure; subordination of interests; payment priority; relative share of interests held across various classes within the VIE’s capital structure; and the reasons why the interests are held by us.
 
In instances where the Company and its related parties have variable interests in a VIE, we consider whether there is a single party in the related party group that meets both the power and losses or benefits criteria on its own as though no related party relationship existed.  If one party within the related party group meets both these criteria, such reporting entity is the primary beneficiary of the VIE and no further analysis is needed.  If no party within the related party group on its own meets both the power and losses or benefits criteria, but the related party group as a whole meets these two criteria, the determination of primary beneficiary within the related party group requires significant judgment. The analysis is based upon qualitative as well as quantitative factors, such as the relationship of the VIE to each of the members of the related-party group, as well as the significance of the VIE's activities to those members, with the objective of determining which party is most closely associated with the VIE.
 
     Ongoing assessments of whether an enterprise is the primary beneficiary of a VIE is required.
 
Derivatives and Hedging Activities
 
Subject to maintaining our qualification as a REIT for U.S. federal income tax purposes, as part of our hedging strategy, we may enter into interest rate swaps, including forward starting swaps, interest rate swaptions, U.S. Treasury options, futures contracts, TBAs, Agency and Non-Agency interest only strips total return swaps, credit default swaps and foreign current swaps and forwards. Derivatives, subject to REIT requirements, are used for hedging purposes rather than speculation. We determine the fair value of our derivative positions and obtain quotations from third parties, including the Chicago Mercantile Exchange or CME, to facilitate the process of determining such fair values. If our hedging activities do not achieve the desired results, reported earnings may be adversely affected.
 
GAAP requires an entity to recognize all derivatives as either assets or liabilities on the balance sheet and to measure those instruments at fair value.  The accounting for changes in the fair value of derivatives depends on the intended use of the derivative. The fair value adjustment will affect either other comprehensive income in stockholders' equity until the hedged item is recognized in earnings or net income depending on whether the derivative instrument is designated and qualifies as a for hedge for accounting purposes and if so, the nature of the hedging activity. We have elected not to apply hedge accounting for our derivative instruments.  Accordingly, we record the change in fair value of our derivative instruments, which includes net interest rate swap payments/receipts (including accrued amounts) and net currency payments/receipts (including accrued amounts) related to interest rate swaps and currency swaps, respectively in "Gain (loss) on derivative instruments, net" in our Consolidated Statements of Operations. 

Proceeds and payments on settlement of swaptions, mortgage put options, futures contracts credit default swaps and TBAs are included in cash flows from investing activities.  Proceeds and payments on settlement of forward contracts are reflected in cash flows from financing activities in our Consolidated Statements of Cash Flows. For Agency and Non-Agency Interest-Only Strips accounted for as derivatives, the purchase, sale and recovery of basis activity is included with MBS and other securities under cash flows from investing activities in our Consolidated Statements of Cash Flows.

We evaluate the terms and conditions of our holdings of Agency and Non-Agency Interest-Only Strips, interest rate swaptions, currency forwards, futures contracts and TBAs to determine if these instruments have the characteristics of an investment or should be considered a derivative under GAAP.  In determining the classification of our holdings of Interest-Only Strips, we evaluate the securities to determine if the nature of the cash flows has been altered from that of the underlying mortgage collateral. Interest-Only Strips, for which the underlying mortgage collateral has been included into a structured security that alters the cash flows from the underlying mortgage collateral, are accounted for as derivatives. The carrying value of our Agency and Non-Agency Interest-Only Strips, accounted for as derivatives, is included in "Mortgage-backed securities and other securities, at fair value" in our Consolidated Balance Sheets.  The carrying value of interest rate swaptions, currency forwards, futures contracts and TBAs

37




is included in "Derivative assets, at fair value" or "Derivative liability, at fair value" in our Consolidated Balance Sheets. Interest earned or paid along with the change in fair value of these instruments accounted for as derivatives is recorded in "Gain (loss) on derivative instruments, net" in our Consolidated Statements of Operations.
 
We evaluate all of our financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. An embedded derivative is separated from the host contact and accounted for separately when all of the guidance criteria are met.  Hybrid instruments that are remeasured at fair value through earnings, including the fair value option, are not bifurcated.  Derivative instruments, including derivative instruments accounted for as liabilities are recorded at fair value and are re-valued at each reporting date, with changes in the fair value together with interest earned or paid (including accrued amounts) reported in "Gain (loss) on derivative instruments, net" in our Consolidated Statements of Operations.

2019 Activity

Investment Activity

We continually evaluate our investment portfolio, focusing on expected future prepayment trends, supply of and demand, costs of financing, costs of hedging, expected future interest rate volatility and the overall shape of the U.S. Treasury and interest rate swap yield curves. We utilized the proceeds from our May secondary equity offering, our two convertible note issuances and net proceeds from sales and paydowns, along with related borrowing to acquire $3.6 billion of investments.

During 2019, due to favorable risk adjusted returns, we opportunistically increased our exposure to Agency RMBS. We continued to see favorable risk-adjusted returns in credit sensitive investments, particularly Residential Whole Loans, Commercial Loans and Non-Agency CMBS. As a result, we continue to deploy capital into these investments. At December 31, 2019, we held $3.1 billion in credit sensitive investments, primarily consisting of 43.8% in Residential Whole Loans, 29.0% in securitized commercial loans (our risk is limited to only our direct ownership interest in the trust), 11.8% in Commercial Loans, 10.1% in Non-Agency CMBS, 1.5% in Non-Agency RMBS, 1.2% in Residential Bridge Loans, and 2.6% in GSE credit risk transfer and ABS securities. We work to mitigate the credit risk on our credit sensitive holdings by developing relationships with originators that adhere to our investment guidelines for our Residential Whole Loans. For our Commercial Loans and other investments, we perform a detailed credit analysis on the underlying collateral at the time of purchase.
